NASAs Perseverance probe landed safely and on time on Mars, at 3:55 p.m. EST, Thursday, marking another success for the U.S. space agency.

The nuclear-powered probe made its way through a harrowing landing process, deemed by some engineers as seven minutes of terror because it involves parachutes, powered descent and a sky crane that gently lowers Perseverance onto a challenging, rocky area of Martian surface.

After a confirmed safe landing, members of the probes Mission Control erupted in applause and cheers.

NASA has now successfully landed nine of 10 probes sent to the Red Planet.

Minutes after touching down, Perseverance beamed back a black-and-white image from the surface as more applause broke out at Mission Control.

The probe is equipped with a microphone, which should have recorded its descent.

Later Thursday, President Joe Biden sent a congratulatory tweet, saying: "Today proved once again that with the power of science and American ingenuity, nothing is beyond the realm of possibility."

Perseverance, and its helicopterlike companion drone, Ingenuity, began the 300-million-mile journey in July. Ingenuity will test if powered flight can be done in Mars thin atmosphere.

The six-wheeled Perseverance, which looks like the other four rover probes that have landed on Mars, set down in Jezero Crater, which is believed to be an ancient lakebed and a potential source for remnants of ancient life.

Determining if Mars once hosted life is the primary goal of the probes two-year mission.

During its search, the probe will take samples from the Red Planets surface and store them in its 43 sample tubes. NASA plans to send another mission to Mars to retrieve the tubes sometime in the early 2030s.

Before collecting samples, NASA will spend the next weeks making sure Perseverances systems are all working.

Perseverance Probe Successfully Lands on Mars - Voice of America

Editors Note: NASA's Perseverance rover successfully landed on Mars on February 18 just before 4 p.m. eastern time. Read more about the mission here.

After a seven-month, nearly 300-million-mile journey to Mars, NASAs Perseverance rover is poised to undertake one of the most challenging engineering feats in human history: touchdown on the red planet.

At 3:55 p.m. eastern time today, the 2,260-pound roverthe heaviest object ever sent to the surface of another planetshould set its wheels in the ruddy dirt of Jezero Crater to begin its search for signs of past life. But to get to the ground, the rover must endure what NASA calls the seven minutes of terror. The spacecraft carrying the rover has been hurtling from Earth to Mars and will slam into the atmosphere at high speed. So in the span of about seven minutes, the spacecraft must slow its descent and settle gently on the surface.

Landing on Mars is really all about finding a way to stop, says Allen Chen, the lead engineer for Perseverances entry, descent, and landing (EDL) system. Perseverance will hit the atmosphere going over 12,000 miles per hour, but it needs to touch down at about two miles per hour.

To land, Perseverance will use a sky crane, a system devised by NASA and used in 2012 to successfully deposit the Curiosity rover in Marss Gale Crater. And, for the first time, video cameras and microphones will capture the full descent of a spacecraft as it lands on Mars. We really want to take people along for the ride this time and see what its like to land on another planet, Chen says.

You can watch live coverage of the landing on NASA TV starting at 2:15 p.m. eastern time, as the mission control team at the Jet Propulsion Laboratory in California track the spacecrafts descent. But the video and audio of Perseverances landing will take more time to transmit to Earth. Due to the current distance between the two planets, sending even a basic radio signal to Earth will take about 11 and a half minutes. And before it can transmit audio or video, the rover must first indicate that it is safe. It will then have several other tasks to perform during its first days on Mars, such as starting up its surface operations software and deploying a mast with its primary science cameras.

If everything goes according to plan, the rover will send back an image tomorrow that will show the view looking down on Perseverance from above. By Monday, the team hopes to release video from the same view. The data for high-quality footage will take longer to transmit and process, so NASA should release high-resolution footage of the entire landing sequence in the coming weeks.

But first, the spacecraft has to make it safely to the surface.

Tucked behind a heat shield, the rover will begin to slow when it hits the atmosphere, like a meteor going across the sky, Chen says. Thrusters will direct the spacecraft toward its landing site as its body produces lift, kind of like an airplane in some ways.

Once it slows to about twice the speed of sound, Perseverance will deploy a 70-foot-wide parachute. You fire this parachute pack out of the back of the vehicle with basically a cannon, Chen says. A new technology called the range trigger will fire the parachute according to how close the spacecraft is to the landing site, allowing Perseverance to target a smaller landing zone than Curiosity, which deployed its parachute once it hit a certain velocity. The spacecraft will then jettison its heat shield and get its first look at the ground using radar and another new system called terrain-relative navigation.

Terrain-relative navigation gives the system eyes, almost literally, Chen says. By snapping photos of the surface and comparing them to onboard maps, which were created from photos taken by spacecraft orbiting Mars, Perseverance can land with enough precision to touch down in an area scattered with boulders and sloped inclines.

The Jezero landing site that were going to was actually rejected as a landing site for Curiosity because it was too unsafe, Chen says. But with terrain-relative navigation and the range trigger system, Perseverance can go where no Mars rover could go before.

Even after the chute has slowed the rover, it will still be hurtling toward the ground at about 160 miles an hour. Thats about as fast as a skydiver would be going, diving straight at the ground without a parachute, here on Earth, Chen says. In the wispy Martian atmosphere, where the air is less than one percent as thick as Earths, a parachute cannot slow the craft any further.

About 1.3 miles above the surface, the spacecraft will release from the parachute and then fire up rocket engines on its descent stage, slowing to about 1.7 miles an hour. At 70 feet above the ground, the descent stage will perform the sky crane maneuver: the landing system will lower the rover to the surface on tethers, then cut the cords and fly off to crash away from the rover.

Perseverance will lower itself from that rocket-powered jetpack thats called the descent stage, deploy its wheelsthats our landing gearand touch down, you know, slower than I can walk, Chen says.

As part of the mission, NASA is planning to capture a Mars landing like never before. A camera on the Curiosity rover filmed some of the missions landing in 2012, but the Perseverance landing will be recorded from all angles. At various stages, and sometimes simultaneously, multiple cameras will be looking up from the descent stage at the parachute, looking down from the descent stage at the rover, looking up from the rover at the sky crane, and looking down from the rover at the ground.

Its the kind of stuff Ive always been trying to imagine, Chen says. The first video, showing the rover touch down as seen from above, could be released as early as Monday, and high-resolution video from all of the cameras will be released in the following weeks.

Perseverance will also record audio of the descent using one of two microphones. Attached to the left side of the vehicle above the middle wheel, one mic is expected to capture sounds of the engines firing, pyrotechnic devices on the EDL system blowing bolts and severing cables, the rush of the wind, and hopefully those wheels actually crunching down onto the surface of Mars, says David Gruel, the assembly, test, and launch operations manager for Perseverance.

And then, for the first time in history, people will be able to listen to what it sounds like on another planet. The microphone will be sitting there on the surface of Mars, attached to the rover, listening to the ambient noises, Gruel says. It will remain on for about a minute after landing, and it could be switched on again for brief recording sessions as long as its temperature-sensitive parts survive the frigid Martian nights.

A second microphone is attached to the rovers SuperCam, an instrument equipped with a laser to vaporize rocks and determine their composition. That mic will listen to rocks being zapped and maybe even the wheels of Perseverance crunching against the desiccated dirt as it rolls across an alien world.

We use a lot of imagery, but weve never used sound to take part or participate as if youre on another planet, Gruel says. Who knows what exciting discoveries we might have with it.

NASAs Perseverance Mars rover set down on an ancient lakebed after a flawless plunge into the Martian atmosphere Thursday, achieving an unprecedented pinpoint landing while delivering the most sophisticated suite of science payloads ever flown to another planet.

The $2.4 billion Perseverance rover arrived at Jezero Crater, a basin that scientists say was once flooded with liquid water, after a nail-biting descent to the Red Planets rust-colored surface.

Wow! We have a science mission, said Ken Farley, Perseverance project scientist from NASAs Jet Propulsion Laboratory.

The nuclear-powered mobile robot capped a seven-month journey from a launch pad at Cape Canaveral with a high-speed dive into the Martian atmosphere. A heat shield cocooned the rover as it streaked through the rarefied air at more than 12,100 mph (19,500 kilometers per hour).

After surviving temperatures near 2,400 degrees Fahrenheit (1,300 degrees Celsius), the rover deployed a supersonic parachute, which billowed open to slow the spacecraft to subsonic speed. Perseverance next jettisoned its heat shield, allowing a landing radar and cameras to scan the Martian surface for a safe touchdown site.

The rovers aerodynamic backshell then released Perseverances rocket-powered descent stage to do the rest of the braking before landing. Eight throttleable engines on the rocket pack slowed the crafts speed to nearly 0 mph, and Nylon cords lowered the one-ton rover to the surface.

Once Perseverances wheels contacted Mars, the descent stage cut the cords and diverted to crash a safe distance away, leaving the rover safely on the ground at Jezero Crater.

We arrived at Mars moving at about 12,000 mph roughly, and just in seven short minutes, we had to slow down and gently put Perseverance down in Jezero Crater, said Matt Wallace, Perseverances deputy project manager at JPL. The system just performed flawlessly, getting through 10 or 12 Gs of deceleration, the supersonic parachute deployment, eight big main engines had to fire ,our terrain relative navigation hazard avoidance system had to perform the way it was designed. Its never easy.

Within minutes, the rover beamed back two low-resolution black-and-white images from its hazard cameras, providing the first-ever views of Jezeros landscape. The images are a taste of whats to come, and scientists expect to have high-definition video, color panoramas, and the first sound recordings from Mars beginning as soon as Friday.

In a post-landing press conference, Wallace said Perseverance is in great shape after arriving on Mars, and is ready for the next phase of a mission packed with firsts.

Ground teams were along for the ride Thursday. With Mars positioned some 127 million miles (204 million kilometers) from Earth, the one-way travel time for radio signals Thursday was more than 11 minutes.

That meant Perseverance followed pre-programmed commands and employed control software to land itself.

The vehicle is going on a roller coaster ride, and you are, too, said Allen Chen, Perseverances entry, descent, and landing lead at JPL.

Things seem to be working the way you want them to go, and you start feeling good then your stomach drops, then things are OK again, Chen said.

Its an emotional roller coaster ride all the way down, and youre second-guessing yourself as you go, even though its already happened, Chen said, referring to the 11-minute time way. Its kind of crazy.

Ground teams at JPL were physically distanced across multiple control rooms due to the effects of the coronavirus pandemic. Many members of the science team monitored the landing remotely.

But the engineers gathered at JPL let out a roar of applause, cheers, and exchanged fist bumps as telemetry confirmed Perseverances successful landing at 3:55 p.m. EST (2055 GMT).

Perseverance reused the same landing architecture demonstrated by NASAs Curiosity rover when it landed on Mars in August 2012. But with nearly a decade of innovation since Curiosity, engineers upgraded Perseverances navigation algorithms to enable a more precise landing.

The rover Thursday navigated to a safe landing site free of steep slopes and boulders. Past Mars landers, without the new terrain relative navigation capability, could have not even attempted a landing on the rugged topography at Jezero Crater, according to NASA.

Chen said the rover ended up about 1.1 miles (1.7 kilometers) from the center of the landing zone.

President Joe Biden called Steve Jurczyk, NASAs acting administrator, to congratulate the Perseverance team after the landing Thursday afternoon. The White House also tweeted a picture of Biden watching the landing from the White House.

Perseverance is the ninth U.S. spacecraft to successfully land on Mars since the Viking missions in 1976. Two international Mars missions the Hope orbiter from the United Arab Emirates and the Tianwen 1 orbiter, lander, and rover from China arrived at the Red Planet earlier this month.

The Chinese Tianwen 1 mission will release its lander and rover to descend to the Martian surface in May or June.

But NASAs Perseverance rover, also known as Mars 2020, has the most ambitious goals of any Mars mission to date.

The rovers primary objective is to search for signs of past life and gather rock samples for return to Earth by future spacecraft in development by NASA and the European Space Agency.

NASA says it spent more than $2.4 billion to design, build and prepare the Mars 2020 mission for launch. With the money budgeted to operate the rover during the trip to Mars, and for around two Earth years (one Mars year) after landing, the total mission will cost around $2.7 billion.

The 2,260-pound (1,025-kilogram) Perseverance rover is about 10 feet (3 meters) long, 9 feet (2.7 meters wide), and 7 feet (2.2 meters) tall.

Jezero Crater, Perseverances landing site, was home to an ancient river delta and a lake the size of Lake Tahoe some 3.5 billion to 3.9 billion years ago. Scientists hope to find signatures of ancient life in the rocks and sediments deposited in the dried-up delta.

This is our first mobile astrobiologist, said Lori Glaze, head of NASAs planetary science division. One of its main purposes is to seek out those signs of past life on Mars.

Perseverance was designed to land as close to the delta deposits as possible. Farley said Thursday the rover ended up near the intersection of two geologic units, and the missions scientific targets will likely be the rocks visible in Perseverances first post-landing images.

The rover was expected to downlink sharper images from its hazard cameras Thursday night through a communications relay with the European ExoMars Trace Gas Orbiter, along with the first views from cameras that recorded high-resolution views throughout the spacecrafts descent. Perseverance carried 25 cameras to Mars, more than any previous mission to the Red Planet.

Wallace said NASA aims to release the new imagery during a press conference Friday.

For the first time, were going to be able to see ourselves, in high-definition video, land on another planet, Wallace said Thursday.

Commercial ruggedized cameras were pointing up at the rovers supersonic parachute, and one on the descent stage looked down at the rover as it prepared for touchdown suspended under Nylon bridles. Other cameras mounted on the rover were programmed to record views looking up and down during the landing.

We think we have captured some pretty spectacular video, and they come with a microphone as well, Wallace said. Perseverance has the first microphones flown to Mars.

I think thats really going to be something to see, he said.

Ground teams have mapped out a carefully-choreographed activation and test sequence for Perseverance over the next several weeks. The rover opened lens covers and released its high-gain communications antenna soon after landing Thursday. If all goes well, the high-gain antenna could obtain a lock with NASAs Deep Space Network as soon as Friday to enable faster data transfers between Earth and Mars, according to Jennifer Trosper, Perseverances deputy project manager at JPL.

Trosper said engineers will spend the first five days known as sols on Mars after landing to stabilize the rovers power, thermal, and communications systems before loading a software update into the spacecrafts computers next week.

A remote sensing mast with the rovers panoramic cameras, science instruments, and a Martian weather station will be raised Saturday, according to Trosper. In parallel with the rover checkouts, controllers will run the rovers seven scientific payloads through health tests and recharge Perseverances battery, fed by a radioactive plutonium power source.

Perseverance will take its first color panoramas this weekend.

After uploading updated software next week, ground teams at JPL will unlimber the rovers robotic arm and send commands for Perseverance to perform its first test drive, likely by rolling about 16 feet (5 meters) forward and background.

One of Perseverances first tasks after completing post-landing checkouts will be to drive to a nearby location to release NASAs Ingenuity helicopter from the rovers belly pan. The rover will drive away to a distance of at least 330 feet (100 meters) before the helicopter flies for the first time.

That moment will be historic. The tiny 4-pound (1.8-kilogram) robot will try to become the first aircraft to fly through the atmosphere of another planet.

Human beings have never flown a rotorcraft outside of our own Earths atmosphere, so this will be very much a Wright Brothers moment, except at another planet, said MiMi Aung, project manager for the Ingenuity helicopter at JPL, in an interview before Perseverances launch last July.

Trosper said Perseverance might be ready to start moving to the helicopter test site in about three weeks, and it might take about 10 days to reach the flight location, depending on the site selected by NASA managers.

Ground controllers will program the helicopter to perform a series of test flights during a planned 30-day campaign, beginning with a relatively simple up-and-down flight lasting less than 30 seconds, Aung said. Then the team will attempt more daring test flights.

The helicopter will fly autonomously, without real-time input from ground controllers millions of miles away. The drone carries two cameras, and telemetry from the helicopter will be routed through a base station on the rover. The Perseverance rover also might be able to take pictures of the helicopter in flight.

NASA officials approved adding the helicopter to the Mars 2020 mission in 2018. The mission cost around $80 million to design and develop, and will cost another $5 million to operate. Agency officials hope the helicopter will prove out aerial reconnaissance as a new method of interplanetary exploration.

Wallace, Perseverances deputy project manager, said this week the Ingenuity helicopter is much like NASAs Sojourner rover, which became the first mobile scout on Mars in 1997 and paved the way for future rovers.

I worked on Sojourner, and there was a lot of uncertainty at the time as to whether or not wed ever really be able to utilize this technology, and we found very quickly that having a mobile capability on the surface of Mars was incredibly valuable, Wallace said. When you look at Ingenuity, it looks very much the same. Its a technology demonstration. Its objective is not tied into the science of this mission. But the potential for aerial reconnaissance and exploration in the future, using this type of technology, is is terrific. Its not just on Mars, but other places as well.

Trosper said Perseverance could be in position for the helicopter test flights this spring, then will move into the missions science campaign to begin examining the geology and ancient habitability of Jezero Crater.

That will lead to the first use of the rovers drill to extract core samples from rocks in the summer, she said.

Members of Perseverances team say the hardware necessary to collect the rock samples and seal them inside ultra-clean tubes was the most complex undertaking of NASAs Mars program to date. The rover has 43 sample tubes on-board, each sheathed in a gold-colored cylindrical enclosure, providing an extra layer of contamination protection. The tubes rode to Mars inside the housings, and they will be returned to their sheaths once filled with Martian rock samples.

The tubes are about the size and shape of a slim cigar, and the 43 cylinders include witness tubes or blanks,which will allow scientists to cross-check rock and sediment specimens returned to Earth for contamination.

Those samples tubes are part of a Sample and Caching System, which is one of our biggest engineering developments for this mission, said Adam Steltzner, chief engineer on the Mars 2020 mission, before the launch last year. We get to Mars largely like the Curiosity rover got to Mars, but we need to do something very different once were on Mars. We must take these core samples, seal them hermetically and sterilely, and then produce a cache of samples for eventual return to Earth.

The rover has a 7-foot-long (2-meter) robotic arm with a coring drill fixed on a 99-pound (45-kilogram) turret on the end. The longer robotic arm will work in concert with a smaller 1.6-foot-long (0.5-meter) robotic manipulator inside the belly of the rover, which will pick up sample tubes for transfer to the main arm for drilling.

Steltzner said the rovers sampling system actually consists of three different robots.

Out at the end of our robotic arm thats the first robot is a coring drill that uses rotary percussive action like we have used similarly and previously on Mars with the Curiosity mission, except rather just generating powder, this creates an annular groove in the rock and breaks off a core sample, Steltzner said.

During each sample collection, the core sample will go directly into the tube attached to the drill.

That bit and the sample tube are brought back by the robotic arm our first robot into the second robot, our bit carousel, which receives the filled sample tube and delivers it to a very fine and detailed robot, the sample handling arm inside the belly of the beast, in which the sample is then assessed, its volume is measured, images are taken, and it is sealed and placed back into storage for eventually being placed in a cache on the surface.

The portion of the caching system inside the rover is called the Adaptive Caching Assembly, which consists of more than 3,000 parts alone.

The design of the drill and sample tubes is intended to preserve the distribution minerals cored from Martian rocks. The system is also intended to collect samples directly from softer soils.

Besides the sampling system, Perseverance hosts seven scientific instruments.

Two of the instruments, named PIXL and SHERLOC, are located alongside the coring drill on the robotic arms turret. Theywill scan Martian rocks to determine their chemical composition and search for organic materials, providing key inputs into decisions by ground teams on which rocks to drill.

The Perseverance rover also carries the SuperCam instrument,an intricate suite of sensors, including a camera, laser and spectrometers, designed to zap Martian rocks from more than 20 feet (6 meters) away to measure their chemical and mineral make-up, with the ability to identify organic molecules.

Developed by an international team in the United States, France and Spain, the SuperCam instrument is an upgraded version of the ChemCam instrument currently operating on NASAs Curiosity Mars rover.

The instruments mounted inside the rovers main body include MOXIE, whichwill demonstrate the production of oxygen from carbon dioxide in the atmosphere of Mars, a capability that future astronaut explorers could use on the Red Planet. A Norwegian-developed ground-penetrating radar on the rover named RIMFAX will study the planets underground geologic structure, yielding data on subsurface layers and soil strength which could help designers of larger landers designed to carry people to Mars.

The mission also carries a weather station and the first camera on Mars with a zoom function. That camera system, located on top of Perseverances remote sensing mast to be raised this weekend, is named Mastcam-Z and will record video and 360-degree panoramas.

The differences between Perseverance and NASAs predecessor Curiosity rover do not stop at the science payload or the Ingenuity helicopter.

The Perseverance roveralso features aluminum wheels with thicker skin and modified treads to avoid damage observed on Curiositys wheels on Mars.NASAs new Mars rover weighs about 278 pounds (126 kilograms) more than Curiosity.

The benefit of another decade of technological advancement since Curiositys launch, and the budding fruits of NASAs partnership with ESA on a Mars Sample Return program, moves scientists closer to addressing the question of whether life took hold elsewhere in the solar system.

Assuming Perseverances mission is a success, and funding and technical plans remain on track, NASA and ESA could launch missions as soon as 2026 with a European-built Mars rover to retrieve the specimens collected by the Mars 2020 mission. The rover will deliver the material to a U.S.-supplied solid-fueled booster to shoot the samples from Mars into space, a feat never before attempted on another planet.

A separate spacecraft provided by ESA will link up with the samples in orbit around Mars, then head for Earth before releasing a NASA re-entry capsule containing the Martian material to complete the first round-trip interplanetary mission no earlier than 2031.

Then scientists will get to work analyzing the samples. They will look for chemical signatures in the core samples that might suggest life once existed on Mars.

Among other objectives, NASAs two Viking landers carried instruments to search for signs of life on Mars when they landed on the Red Planet in 1976. But the robotic landers did not produce any verifiable confirmation of life, andMars missions since Viking have followed the trail of water, seeking evidence that the Red Planet once harbored environments that could have supported basic life forms.

Two other NASA robots are still exploring the surface of Mars. Curiosity has been surveying Mount Sharp in Gale Crater since 2012, and the stationary InSight seismic station landed on Mars in 2018.

NASA rover reaches Mars on mission in search for signs of past life Spaceflight Now - Spaceflight Now

Legendary Apollo 11 astronaut Edwin "Buzz" Aldrin on Saturday hailed "all the folks" at NASA and its Jet Propulsion Laboratory (JPL) on the successful landing of the Perseverance rover on the surface of Mars.

Aldrin, the second man to walk on the moon, following Neil Armstrong, during the Apollo 11 mission in July 1969, shared his observations during a call-in interview on Fox News "Cavuto Live."

The New Jersey native, who turned 91 in January, has long been an advocate of efforts by the U.S. space program to explore Mars, the next planet after Earth in the direction away from the Sun.

Fox host Neil Cavuto began the segment by sharing the latest video images from Mars that were captured by Perseverance, the fifth rover that NASA has sent to the planet and ninth overall NASA landing there, according to The Associated Press.

HOW WILL NASAS PERSEVERANCE ROVER ENGINEERS PILOT FIRST HELICOPTER ON MARS?

He then asked Aldrin for his reaction to the Marslanding.

"I think its a great tribute to all the folks at NASA, led by Jim Bridenstine and all the other people, especially those in the control room at JPL," Aldrin said.

Bridenstine, the NASA administrator who was appointed by former President Donald Trump, left the agency Jan. 20, as President Biden took office.

Cavuto later asked Aldrin to estimate what year humans will be able to reach the surface of Mars.

"About 10, 20 years ago, my estimate was around 2030, 2033, and that was earlier than most other people were figuring," Aldrin responded.

"Weve got to do a good number of things in Artemis, our manned program to the moon ," he continued. "So its gonna take the first one at the moon and then the public is going to be ready to see the next, which will be a sophisticated improvement on manned missions."

Other planned missions to Mars include the landing of a smaller rover by China, scheduled for late spring, and a spacecraft from the United Arab Emirates that went into Martian orbit last week, the AP reported.

Aldrin was previously in the news in January when he received his first coronavirus vaccine shot, just days ahead of his 91st birthday.

"I urge everyone to sign up for a vaccination as soon as possible when eligible to do, so that life can return to normal soon," Aldrin wrote on Twitter.

Buzz Aldrin reacts to NASAs Perseverance rover landing on Mars - Fox News

Mars rover Perseverance has landed on the surface of Mars after a white-knuckle descent involving picking a landing spot just moments before making a rocket-powered sky-crane landing. The rover immediately sent back its first image of Jezero Crater, which it will be exploring over the course of its mission.

A clearly tense but optimistic team watched as Perseverance made its final approach to Mars a few hours ago, confirming it was on track to hit the bullseye of Jezero Crater, the ancient delta where the rover will soon be roving.

Except for a few brief but expected communications blackouts caused by the superheated air around the craft as it entered the thin Martian atmosphere, the lander sent back a continuous stream of updates to the team on Earth considerably delayed, of course, by the distance to the other planet.

The team, and charmingly the on-screen hosts at mission HQ audibly gasped, whispered yes! and made other signs of their excitement as news trickled in that atmosphere entry had occurred on time, that the craft hadnt broken up during the 10-G braking maneuver, that the parachute had deployed, that a landing site was found by the ground-facing radar, that the powered descent and sky crane had commenced and, at last, finally that the rover had safely touched down on the surface.

Cheering but, in accordance with COVID-19 precautions not (as they normally would) hugging each other, the team celebrated the landing and soon were treated to the first images sent back from the rover.

These initial pictures are low-quality ones sent just seconds after landing by the hazard camera, a fisheye used for navigation. As the dust settles (literally) and the rover initiates its more powerful devices and cameras, well have new, color images probably within an hour or two.

For a more complete look at the mission and its remarkable landing method, you can read yesterdays profile of the Perseverance mission. The next few days will probably be less exciting than the terror-inducing landing, but soon the rover will be up and running around Jezero, looking for evidence of life on Mars and testing technology that could be used by human visitors in the future.

Were not ready to go there with astronauts yet, but the robots are ready, said JPL director Michael Watkins on the broadcast. We start by sending, you know, our eyes and arms there in the form of a robot. It is just fantastic to be able to do that, and to learn from each rover, learn from the science and the engineering, and make the next one better, and make more and more discoveries. Every time we do one of these missions, we make fabulous discoveries and you know, each one is more exciting than the last.

The exciting thing everyone is looking forward to, Mars helicopter Ingenuity, will hopefully take flight soon as well.

We have a series of major milestones between now and the first flight. Tomorrow, well turn on the helicopter, and the space station could confirm its health. The next major milestone will be when the rover deploys the helicopter on the surface, and that marks the first moment that Ingenuity operates on its own in a standalone manner, said MiMi Aung, project manager and engineering lead for Ingenuity. Surviving that first cold frigid night of Mars will be a major milestone, then well execute a series of checkouts, and then we will perform that very important first flight. And if the first flight is successful, we have up to four more flights in the 30 Martian days that we have set aside for our flight experiments.

The helicopter project will definitely be novel, but its not just about recording a first for the sake of NASA being able to say they did it; Ingenuity will hopefully lay a firm technical foundation for future exploration.

A helicopter flying far ahead of rovers and astronauts in the future can provide high-definition reconnaissance information for the rovers and the astronauts before they take long journeys, Aung said. And as importantly, being able to fly will enable us to get to places that we cannot get to with rovers and astronauts, like sides of steep cliffs, deep inside crevices, all areas of high scientific interest. It will be game changing.

Perseverance lands safely on Mars and sends back its first images of the surface - TechCrunch

NASAs newest robotic explorer has landed safely on Mars after a nearly 300-million-mile journey that began on a Florida launch pad.

The agencysPerseverance rovertouched down on the Red Planet at 3:55 p.m. EST Thursday, bringing an end to the seven minutes of terror that saw a fiery atmospheric entry and parachute-assisted descent. The rovers landing mechanism then firedeight retrorockets to slow down and guide it to a proper landing spot before using nylon cords to lower it onto the surface.

"Touchdown confirmed! Perseverance is safely on the surface of Mars, ready to begin seeking the signs of past life," exclaimedNASA engineer Swati Mohan.

All told, the unique landing maneuver successfully decelerated Perseverance from thousands of miles an hour to just 1.7 mph at touchdown. And because ofan 11-minute delay in transmissions from Earth to Mars, the rover did it all on its own no human input was possible.

Mission managers at NASA's Jet Propulsion Laboratory in California quickly received data from Mars satellites and the rover itself confirming a good touchdown, including the first images from Perseverance: scenes of a desolate, dusty landscape that looks dangerous to humans but full of potential for this scientist-explorer.

"We got it. We're there," JPL Chief Engineer Rob Manning, who has worked on Mars landings for decades,said after landing."This is so exciting and the team is beside themselves. This is so surreal. So much has been riding on this."

Just minutes after the landing, Perseverance continued sending imagesfrom its hazard-detecting navigational cameras.

Manning also confirmed teams knew exactly where the rover landed well ahead of schedule.

"This is a sign that NASA works," Manning said."When we put our arms together and our hands together and our brains together, we can succeed. This is what NASA does and this is what we can do as a country."

The Red Planet's newcomer now finds itself in Jezero Crater, a region of Mars once believed to harbor a massive lake fed by rivers of running water. The regolith and rocks here will be prime targets for Perseverance's suite of instruments designed to hunt for past or present signs of life.

Live video was made possible by NASA during Perseverance's approach, entry, descent, and landing.

Perseverance is our robotic astrobiologist, and it will be the first rover NASA has sent to Mars with the explicit goal of searching for signs of ancient life, said Thomas Zurbuchen, associate administrator of NASAs Science Mission Directorate.

Though Perseverance isn't the first rover on Mars the U.S. and other countries have been targeting the Red Planet for decades it's the most advanced and fastest, and it will likely survive longer than its predecessors in this harsh, dustyenvironment.

Unlike older rovers that relied on solar power, for example, Perseverance runs on nuclear power. This is especially important on a planet where massive, global dust storms can render solar panels useless.

"It's the biggest and best rover that we've ever sent to Mars," said NASA's Director of theJet Propulsion Laboratory Mike Watkins. "It can really do amazing things in terms of its own scientific exploration of this habitable environment at Jezero."

NASA expects Perseverance's surface mission to last about one Martian year, or two Earth years.

The 2,200-pound rover, nearly identical though slightly larger than its 2012 Curiosity predecessor, has several suites of onboard instruments that will be used to find, analyze, and store rock samples. A drill on the end of its "arm" is designedto grab core samples, while systems that use X-rays and ultraviolet spectrometers can conduct scientific investigations right there on the surface.

There's some forward-thinking, too: Perseverance can not only store its core samples in tubes and put those in its "body," but it can later remove and scatter them around the surface of Jezero Crater for a yet-to-be-scheduledsample return mission. Though Perseverance is no slouch with its onboard instruments, scientists hope to use their own tools and equipment on samples obtained directly from Mars.

Manasvi Lingam, a professor of astrobiology, aerospace, physics and space sciences at Florida Tech, said bringing samples back to Earth hastwo advantages for scientists: the breadth and number of instruments available on Earth vastly outclass whats available on Perseverance; and despite technological advances, having a human eye looking at samples is still the preferred method.

Any sign of life will of course be one of the most momentous discoveries in the entire history of humanity, Lingam said. Even if it is extinct life, just knowing that there was something out there is certainly Nobel Prize-level.

Nicknamed "Percy" by her Jet Propulsion Laboratory mission managers, NASA's latest rover isn't alone in Jezero Crater. A small, 4-pound helicopter named Ingenuity hitched a ride down to the surface on the rover's "belly."

Ingenuity's mission is simple and unrelated to the larger science objectives: conduct the first-ever flight on another world. To accomplish this in an atmosphere just 1% as dense as Earth's, NASA had to build a small vehicle with large carbon fiber blades and make it light enough to lift off.

Using two cameras, the small helicopter will attempt the first test flights over a yet-to-be-determined 30-day period.Ingenuity could offer robotic and human explorers of the future a critical high-level view of the planet.

Perseverance began its journey to Mars in July 2020 on a United Launch Alliance Atlas V rocket, which vaulted the payload on a complicated trajectory from Cape Canaveral Space Force Station in Florida.

"We or our heritage rockets have done every U.S. mission to Mars, so it's something that's really special to us," Tory Bruno, CEO of ULA, told Florida Today, part of the USA TODAY Network. "We're really excited and honored to be trusted with a mission like this to Mars."

Bruno said all missions are important, but science-focused ones like Perseverance have a special place in his company, which is focused on its next-generation Vulcan Centaur rocket for flights of all types.

"The missions we launch are always important," Bruno said. "This is some group of people's life's work. The research they have done leading up to this and the work on the spacecraft itself is a career all alone."

"If you lose that spacecraft or you don't deliver it the way it needs to be delivered in order for it to do its mission, sometimes there's no recovering from that. Their whole career culminated in this mission and they don't have a second career to do another one," Bruno said.

"We take that very, very seriously."

Perseverance rover successfully lands on Mars, a key step in NASAs search for signs of life - USA TODAY

Just minutes after NASA's Perseverance rover stuck its landing on Mars, it sent back two historic images our first-ever views of the red planet from the elusive Jezero Crater.

Percy, as the rover is nicknamed, got through the "seven minutes of terror" on Thursday a series of make-or-break events to land. A successful landing was announced just before 4 p.m. ET from NASA's Jet Propulsion Laboratory (JPL) in California.

"Touchdown confirmed! Perseverance is safely on the surface of Mars, ready to begin seeking the signs of past life!" Swati Mohan, a guidance, navigation and control officer monitoring telemetry at JPL, called out as the rover landed. Socially-distanced flight engineers burst into cheers and applause as they breathed a collective sigh of relief.

Just moments later, scientists received the rover's first two pictures, showing a rocky view of the rover's new home.

One of the rover's Hazard Avoidance Cameras, which primarily help with driving, snapped the black-and-white shots. The camera is partially obscured by a clear protective cover. Later images from the rover will be higher-resolution.

Percy itself can also be seen in the first image its large shadow announcing its arrival.

The photos mark one of the rover's first successes, and show the team on Earth that it made it to Mars safely.

"Hello, world. My first look at my forever home," the rovertweeted upon arrival.

President Joe Biden watched the rover landing live from the White House.

"Congratulations to NASA and everyone whose hard work made Perseverance's historic landing possible," he tweeted. "Today proved once again that with the power of science and American ingenuity, nothing is beyond the realm of possibility."

Scientists said they hope to view "pretty spectacular" video and audio footage, as well as additional photos, within the next few days.

The rover, NASA's most sophisticated to date, will soon begin its hunt for signs of ancient life. Billions of years ago, the Jezero Crater was home to a large lake, and Percy will collect samples that will be the first to make the trek back to Earth for scientists to examine.

During the first month, they also plan to test a small 4.5-pound, $80 millionhelicopter named Ingenuity. It will attempt the first powered flight in the thin Martian air, a "Wright brothers' moment" on another world.

NASA reveals first two photos of Mars taken by the Perseverance rover - CBS News

The possibility of life on Mars has excited the imagination. Among the scientific community, the current thinking is that life may have existed on the earths ruddy planetary neighbour a long time ago. Understanding this will enrich our studies of evolution and nurture of life outside the earth. The recent NASA mission, Mars 2020, that was launched from Cape Canaveral, Florida on July 30, 2020, landed on the Jezero Crater in Mars on February 18, to much celebration. Of special magnificence was the entry, descent and landing of the missions Perseverance rover, described as the shortest and most intense part. Entering the Martian atmosphere at about 20,000 km per hour, the mission had to bring the Perseverance rover to a halt on the surface in just seven minutes. Also, since it takes 11 minutes for a radio signal to reach the earth from Mars, the mission control could not really guide the landing, and the rover had to complete this process by itself. During the complicated landing process, using a camera eye, the rover checked the ground below to avoid hazardous terrain, all in a few breathtaking minutes.

NASAs exploration of Mars has focused on finding traces and trails of water that may have existed, and relate it to finding evidence of ancient life. Its earlier Mars expedition which carried the Curiosity rover, landed on August 5, 2012. It identified regions that could have hosted life. Expected to last at least the duration of one Mars year, or about 687 earth days, the science goals this time are to look for signs of ancient life and collect rock and soil samples. Perseverance will take the inquiry made by Curiosity to the next level and search for signs of past life by studying the Jezero Crater. The crater was chosen for study as based on an earlier aerial survey, it was found to be home to an ancient delta. Clay minerals and carbonates were seen, making the crater a good place to search for lifes existence. Further, the rover will study the geology here and store samples in a place that can be accessed by a future mission which would return them to the earth. The rover will test out technologies that could help sustain the presence of humans there in the future. This includes an instrument to extract oxygen from the atmospheric carbon dioxide. The rover also carries a helicopter named Ingenuity that is specially designed to fly in Marss thin atmosphere; its sole purpose would be to demonstrate flight on Mars. Finally, to the question whether little green microbes did inhabit Mars in the distant past only time and Perseverance can answer that.

Time and perseverance: On NASAs rover on Mars - The Hindu

In his Healy home on Thursday, 10-year-old Kyler Frazier, dressed in a blue NASA shirt, cheered as the federal space agencys new Mars rover landed on the red planet.

The 2,260-pound rover touched down in the bowl of a dried-out crater lake and carried with it unusual cargo: a minuscule, stenciled copy of a short essay written by the fourth grader.

I was so excited, I clapped with all the Mission Control people. And my baby brother clapped with me, Kyler said.

He is one of three students in Alaska who were chosen as semifinalists in a contest to name the new rover. The contest received more than 28,000 entries. The winner, seventh grade student Alex Mather of Virginia, gave the rover its name: Perseverance.

But essays written by all 155 semifinalists were carried on a 293-million-mile journey by the spacecraft to the planet. The essays are stenciled onto a tiny silicon chip mounted to the top of the rover.

It was really exciting to find out that I was one of those 155 people, and I thought I was the luckiest kid in the world, Kyler said.

Arabella Batori of Cantwell and Katelyn Stiles of Juneau were also semifinalists. Arabella, a junior at Cantwell School, turned 17 on Thursday.

Im just excited that it happened on my birthday and I was able to be a part of that. And now Ill always remember it, she said.

The rover is seeking signs of past microbial life and will document the planets climate and geology. The rover is also collecting samples that will be returned to Earth.

Kylers mother, Samantha Frazier, said the family heard about the contest through a Facebook group for their small Interior Alaska community.

Kyler said, I really like space, and Mars is probably my favorite planet and I like robots so I thought, space robot why dont I try to name it?

Kyler, who was a third grader at Tri-Valley School when he submitted his essay, chose the name Wonderment.

The word wonderment means respected and admired and wondering means when you want to know something, Kyler wrote in his essay. I chose this name because the Rover should be both respected and admired. The Rover will be trying to discover something that it doesnt already know. Not everyone or anything can go to space so thats a pretty good goal and something to look up to.

Frazier said her son has always been fascinated by space.

When he found out Pluto isnt a planet anymore, I think he cried for a solid hour. He must have been in preschool, she said. But he just always loved it. Hes had a passion that hes taught me to love.

Arabella said that she suggested the name CMAR, which stands for Cantwell Mars Alaska Rover a creative acronym to honor her beloved community.

I wanted to maybe promote Cantwell a little bit because even though were really small, were a really wonderful place, she said. There are only about 10 students in her school, she said.

Arabella said she was encouraged to submit an essay by teacher Marie Gore, who she said likes to get the students to try to recognize that they have just as much of a chance of winning as a student from a bigger school.

At first, Arabella couldnt think of any names for the rover, she said. But then she thought about how much she loves her hometown.

We are super, super small, she said. Still, with that comes a great sense of community, she said.

So I like that I have a lot of family here. And I like that we have such beautiful lands where we can go hiking and fishing and hunting, she said.

Arabella also watched the landing, which was broadcast live, on her phone with her fellow students cheering during class Thursday.

I could hear people in the next classroom, the elementary, they were all excited because they were watching it live too, she said.

In Juneau, Katelyn, 14, said that she learned about the contest as an assignment in a middle school computer class and suggested the name Perception.

I was also super competitive, so I just kind of put it there. I didnt think it would actually get anywhere, though, she said.

Katelyn thought Perception would be an apt name because it describes the rovers mission and follows the theme of previous rovers, which have been named Sojourner, Spirit, Opportunity and Curiosity.

Now a freshman at Thunder Mountain High School, Katelyn was surprised to learn during an interview with the Daily News that her essay had made it all the way to Mars.

It feels weird, she said of the idea that her written words are now on Mars. She said she was worried that there was a mistake in her essay. (There is not.)

Even the aliens will facepalm, she said.

Still, I have bragging rights now, she said.

Perseverances mission is part of NASAs Moon to Mars program, which aims to pave the way for human exploration of the red planet and the moon.

Kyler said he hopes to someday explore Mars himself as an astronaut and perhaps find that the stencil of his essay still remains.

Lori Glaze, director of NASAs Planetary Science Division, said that the lines of text on the silicon chip are smaller than one-thousandth the width of a human hair, according to the Fairbanks Daily News Miner.

I hope to go there and see it one day, but I probably need a magnifying glass, Kyler said.

3 Alaska students' essays have landed on Mars, carried by NASA's Perseverance rover - Anchorage Daily News

Perseverance is not just another Rover Mission. Perseverance is the most advanced, most expensive and most sophisticated mobile laboratory sent to Mars. The results of the experiments on Perseverance will likely define the next couple of decades of Mars exploration it will determine the course of search for life and a future manned mission to Mars.

We have come a very long way in understanding Mars from the time of the first generation missions in the 1960s. The Viking missions in the mid-seventies carried out the first chemical analysis of Martian soil, as well as four biology experiments to detect biological activity. The experiments did not yield any conclusive evidence of life.

In the early 1980s, scientists hypothesised, based on mineralogic composition and rock texture, that certain meteorites might have a source region in Mars, in contrast to the asteroid belt. In 1984, a study showed that the isotopic composition of rare gases (Xenon, Krypton, Neon and Argon) matched the isotopic ratios of the Martian atmosphere measured by the Viking spacecraft. This discovery provided a way for geochemists to study Martian samples and provided a huge boost to our understanding of the geochemical evolution of Mars.

Mars was considered to be a dry planet in the 20th century. This changed in 2001, when the Gamma Ray Spectrometer on board the Mars Odyssey spacecraft detected a fascinating hydrogen signature that seemed to indicate the presence of water ice. But there was ambiguity this was because hydrogen can be part of many other compounds as well, including organic compounds.

To test for the presence of water, NASA sent a spacecraft to land near the Martian South Pole in 2007. The spacecraft studied the soil around the lander with its robotic arm and was able to establish, without any ambiguity, the presence of water on Mars for the first time.

The Curiosity rover carries an instrument called SAM (or Sample Analysis at Mars), which contains a suite of spectrometers with the goal of detecting organic compounds on Mars. SAM has a mass spectrometer that can measure not just the elements, but the isotopes as well. This instrument has made the fascinating discovery of large chain organic compounds on Mars. It is not known how these organics form on Mars: the process would likely be inanimate, but there is a fascinating possibility that such complex molecules were formed by processes associated with life.

Mars Insight is creating history right now, by monitoring seismic activity and heat flow on Mars this will help understand the composition of the Martian interior.

Dr Amitabha Ghosh is a NASA Planetary Scientist based in Washington DC. He has worked for multiple NASA Mars Missions starting with the Mars Pathfinder Mission in 1997. He served as Chair of the Science Operations Working Group for the Mars Exploration Rover Mission, and was tasked with leading tactical Rover Operations on Mars for more than 10 years. He helped analyse the first rock on Mars, which incidentally happened to be the first rock analysed from another planet.

Why is Mars so interesting to scientists? And to the explorer-adventurer in all of us? There are two primary reasons.

First, Mars is a planet where life may have evolved in the past. Life evolved on Earth 3.8 billion years ago. Conditions on early Mars roughly around 4 billion years ago were very similar to that of Earth. It had a thick atmosphere, which enabled the stability of water on the surface of Mars. If indeed conditions on Mars were similar to those on Earth, there is a real possibility that microscopic life evolved on Mars.

Second, Mars is the only planet that humans can visit or inhabit in the long term. Venus and Mercury have extreme temperatures the average temperature is greater than 400 degree C, or hotter than a cooking oven. All planets in the outer solar system starting with Jupiter are made of gas not silicates or rocks and are very cold. Mars is comparatively hospitable in terms of temperature, with an approximate range between 20 degrees C at the Equator to minus 125 degrees C at the poles.

Perseverance addresses both the critical themes around Mars the search for life, and a human mission to that planet.

Sample Return Mission: Is there life on Mars?

Perseverance is the first step in a multi-step project to bring samples back from Mars. The study of the returned rock samples in sophisticated laboratories all over the world will hopefully provide a decisive answer on whether life existed on Mars in the past.

Here are the steps in the Sample Return:

As the first step, Perseverance will collect rock and soil samples in 43 cigar-sized tubes. The samples will be collected, the canisters will be sealed, and left on the ground.

The second step is for a Mars Fetch Rover (provided by the European Space Agency) to land, drive, and collect all samples from the different locations, and return to the lander.

The Fetch Rover will then transfer the canisters to the Ascent Vehicle. The Mars Ascent Vehicle will meet with an Orbiter after which the Orbiter will carry the samples back to Earth.

This long-term project is called MSR or Mars Sample Return. MSR will revolutionise our understanding of the evolutionary history of Mars. If MSR is successfully executed, we will have a reasonable answer of whether there was microscopic life on Mars.

But MSR does have its risks. If one of the components fails, like the Fetch Rover or the Mars Ascent Vehicle, MSR is doomed. A hidden risk is strategic. At the cost of MSR, there could be 5-10 spacecraft missions to different parts of the solar system: so hence, by choosing MSR, NASA forecloses the option to undertake those other missions.

Producing oxygen on Mars: A critical requirement

For a human mission to Mars to materialise, the cost needs to be reasonable. For costs to be reasonable, there needs to be a technology and infrastructure in place to manufacture oxygen on Mars using raw materials available on Mars.

Without a robust way to manufacture oxygen on Mars, human missions to Mars will be very expensive, and unrealistic. Without a reliable oxygen production plan on Mars, Elon Musks plan to provide commercial transportation to Mars will be at risk of failure.

Perseverance will have an instrument MOXIE, or Mars Oxygen In-Situ Resource Utilisation Experiment that will use 300 watts of power to produce about 10 grams of oxygen using atmospheric carbon dioxide.

Should this experiment be successful, MOXIE can be scaled up by a factor of 100 to provide the two very critical needs of humans: oxygen for breathing, and rocket fuel for the trip back to Earth.

Looking for underground water on Mars

Perseverance will carry the Radar Imager for Mars Subsurface Experiment (RIMFAX). RIMFAX will provide high resolution mapping of the subsurface structure at the landing site. The instrument will also look for subsurface water on Mars which, if found, will greatly help the case for a human mission or the cause of a human settlement on Mars.

Testing a helicopter to fly on Mars

The Mars Helicopter is really a small drone. It is a technology demonstration experiment: to test whether the helicopter can fly in the sparse atmosphere on Mars.

The low density of the Martian atmosphere makes the odds of actually flying a helicopter or an aircraft on Mars very low. Long-distance transportation on Mars has to rely on vehicles that rely on rocket engines for powered ascent and powered descent.

We are perhaps a decade from two milestones in the exploration of Mars: a human mission to Mars, and a decisive answer to the question of whether Mars harboured or still harbours microscopic life. Perseverance is expected to provide significant insight on both questions.
