Curiosity's Secrets: The Hidden Features of NASA's Mars Rover

NASAs newest Mars rover, Curiosity, is an awesome scientific machine. By now, you probably know all about its rock-blasting laser and its 17 amazing cameras.

But here and there, Curiosity is hiding a few secrets. Scattered around its body are little mostly unknown bits and pieces. You might have noticed them in images and said, like we did, Huh, I wonder what that is.

Well, here we take a very close-up and detailed look at the rover to answer some of those questions. Some of these features helped Curiosity pull off a flawless landing on the Martian soil. Other bits are there to assist in the day-to-day science collecting that will allow the rover to figure out the history of water on Mars and whether the planet was ever capable of sustaining life.

Curiositys engineers seem to love pyrotechnics even more than Burning Man enthusiasts do. During the spacecrafts harrowing entry, descent, and landing sequence, it fired off 76 blasts to separate the pieces of the plummeting probe. Some of the pyrotechnics (which are essentially very controlled fireworks) had the energy of a box of matches while others contained the explosive force of a dynamite stick.

Just before Curiosity entered the Martian atmosphere it fired 10 pyrotechnics within five milliseconds Pow! Pow! Pow! some of which released miniature guillotines to cut connecting cables while the rest actually separated the entry capsule and the cruise stage. Other blasts released the spacecrafts tungsten ballast weights (which were later spotted by the Mars Reconnaissance Orbiter satellite). The biggest boom was responsible for unfurling the rovers supersonic parachute, the largest ever used on an interplanetary mission.

Even on the ground, the rover still had a few more bangs to go. Engineers needing to remove the cameras dust-blocking lens caps turned to -- what else? -- small pyrotechnic devices.

Nasa's Mars rover zaps first rock

20 August 2012 Last updated at 07:32 ET By Jonathan Amos Science correspondent

Nasa's Curiosity rover has zapped its first Martian rock.

The robot fired its ChemCam laser at a tennis-ball-sized stone lying about 2.5m away on the ground.

The brief but powerful burst of light from the instrument vaporised the surface of the rock, revealing details of its basic chemistry.

This was just target practice for ChemCam, proving it is ready to begin the serious business of investigating the geology of the Red Planet.

It is part of a suite of instruments on the one-tonne robot, which landed two weeks ago in a deep equatorial depression known as Gale Crater.

Over the course of one Martian year, Curiosity will try to determine whether past environments at its touchdown location could ever have supported life.

The US-French ChemCam instrument will be a critical part of that investigation, helping to select the most interesting objects for study.

The inaugural target of the laser was a 7cm-wide rock dubbed "Coronation" (previously N165).

It had no particular science value, and was expected to be just another lump of ubiquitous Martian basalt, a volcanic rock.

NASA's 'Mighty Eagle' lander passes test

NASA's "Mighty Eagle" a robotic prototype for new landers to explore the moon and beyond has passed a major test with its first successful free flight, the space agency announced this week.

Without using a tether (a first for the vehicle), the lander took off, hovered at about 33 feet (10 meters), flew sideways, and landed safely on its prescribed target, video of the the Aug. 8 test flight shows. The entire flight lasted 34 seconds and took place at NASA's Marshal Space Flight Center in Huntsville, Ala.

NASA plans to use the Mighty Eagle to develop new robotic landers to send to the moon, near-Earth asteroids and other airless celestial bodies

The three-legged spacecraft is 4 feet (1.2 m) tall and 8 feet (2.4 m) in diameter. It weighs 700 pounds (317 kilograms) when filled with its fuel, which is made up of 90 percent pure hydrogen peroxide, according to NASA.

After the lander's previous round of testing in 2011, engineers upgraded the guidance controls on the lander's camera, improving its autonomous capabilities, NASA officials said. In tests scheduled through September, engineers plan to get the lander flying and hovering autonomously at up to 100 feet (30 m).

"These lander tests provide the data necessary to expand our capabilities to go to other destinations," Greg Chavers, engineering manager at the Marshall Center, said in an Aug. 13 statement. "It also furthers our knowledge of the engineering components needed for future human and robotic missions."

The Mighty Eagle's successful untethered flight came one day before another NASA lander prototype's fiery test failure at the agency's Kennedy Space Center in Florida. In that Aug. 9 test flight, engineers with NASA's Project Morpheus based at the Johnson Space Center in Houston attempted to make the first untethered flight of the Morpheus lander over a mock moonscape.

A failure caused the Morpheus lander to flip over and explode shortly after liftoff. Project Morpheus officials are studying the failure and plan to upgrade a second Morpheus lander for future tests.

Scientists plan to blast a Martian rock called N165 with Curiosity's laser, which is part of the rover's remote-sampling ChemCam instrument. The 3-inch-wide (7.6 centimeters) stone sits just 9 feet (2.7 meters) from Curiosity, well within ChemCam's 25-foot (7.6 m) range, scientists said.

"Our team has waited eight long years to get to this date, and we're happy that everything is looking good so far," ChemCam principal investigator Roger Wiens, of Los Alamos National Laboratory in New Mexico, told reporters today (Aug. 17). "Hopefully we'll be back early next week and be able to talk about how Curiosity's first laser shots went."

Curiosity, which landed in Mars' huge Gale Crater on Aug. 5, is also gearing up to move its six wheels for the first time. The rover's handlers have said a short test drive could take place around Sol 15 mission lingo for Curiosity's 15th full day on the Red Planet which corresponds to Monday or Tuesday (Aug. 20 or 21) Earth time.

Also today, scientists announced the target destination for Curiosity's first big trek a spot 1,300 feet (400 m) or so east of the rover's landing site that the mission team has dubbed Glenelg. Researchers chose it because Glenelg harbors three different geological units for Curiosity to study. [Photos: Glenelg on Mars - Latest Curiosity Rover Views]

"This was a natural target to pick up," said Curiosity chief scientist John Grotzinger, a geologist at Caltech in Pasadena. "It looks really obvious."

ChemCam, which is short for Chemistry and Camera, fires a laser at Mars rocks and then determines their chemical makeup by analyzing the vaporized bits. It's one of 10 instruments designed to help Curiosity determine if Mars has ever been capable of supporting microbial life.

NASA: Mars Curiosity Ready to Roam, Shoot Lasers

With the Mars Curiosity rover's science instruments working well, NASA engineers are getting ready for two big tests of their robotic rover -- blasting a rock with a laser beam and getting the rover moving.

Curiosity's first drive will be a very short one. Before the rover starts any meaningful trek across the Martian surface, scientists will first simply drive it forward and back in the landing area, to test the wheels and motor system, according to John Grotzinger, a project scientist with NASA's Jet Propulsion Laboratory and a geology professor at the California Institute of Technology.

"The excitement from the science team is that all the instruments continue to check out," he said during a press call Friday. "If we continue down the nominal path, it's probably going to be a couple of days. Sometime next week you'll hear about successful tests of the first wheel motions."

Once the wheels are successfully tested, scientists will continue to plot out Curiosity's first real trek, which will take it west toward an area NASA has dubbed Glenelg.

"The Glenelg area -- it simply looks distinctive and interesting," said Grotzinger. "It looks cool. Let's go there and see what's there."

It is expected to take the rover three to four weeks to reach Glenelg unless the rover encounters rocks or soil that scientists want it to stop and analyze. Once it reaches its first destination, Grotzinger said the rover will probably spend about two months analyzing that area.

Toward the end of the year, NASA engineers will begin to have Curiosity move toward Mount Sharp, a three-mile high mountain in the middle of Gale Crater, where the rover landed. Mount Sharp is a primary area of interest for the scientists who are hoping to discover if Mars has ever been able to support microbial life.

However, before the rover begins heading to Glenelg, scientists want to test its laser.
