At Ceres, NASA's Dawn spacecraft reemerging into the light

Posted on by

Its almost showtime, Ceres. NASAs Dawn spacecraft has sent back the first images of the dwarf planet after spending about a month approaching from the mysterious little worlds dark side, officials at Jet Propulsion Laboratory said Friday.

They are on the ground, Dawns deputy principal investigator, Carol Raymond, said in an email, adding that the images will be released early next week.

Ceres is one of five dwarf planets in the solar system, and the largest member of the asteroid belt that lies between Mars and Jupiter. Scientists think that studying this icy little world will shed light on the early evolution of our solar system.

Until Dawns arrival March 6, little had been known about this frigid protoplanet. Fridays images, taken from about 20,500 miles from the surface, are roughly 9.5 times better than images taken by NASAs Hubble Space Telescope in 2003 and 2004, which were once the best available shots of the dwarf planet.

Even with this improved resolution, Fridays snapshots may not be quite as impressive as earlier images taken during Dawn's approach, because they'll only show Ceres in partial daylight and will be used only for navigation purposes, scientists said.

We want to see exactly where Ceres is relative to ourselves and the star background, said UCLA planetary scientist Christopher Russell, the missions principal investigator.

A few more navigation images will be taken next week, but the high-quality images that will signal the start of the science mission will come late this month, the scientists said.

We are expecting to resolve the bright spots with the next set of images, Russell said, referring to the mysterious, luminous areas on the surface that have piqued the interest of scientists and lay folk alike.

The bright spotsmay be filled with relatively fresh material perhaps rich in water ice or salts, Russell said. But until they get a better look, theres no way to say for sure.

In the meantime, Hubbles blurry, decade-old snapshots may also still prove useful, because they will allow scientists to pick out any major changes over time.

NASA: We'll find alien life by 2025

Story highlights NASA chief scientist Ellen Stofan believes we're close to finding alien life Indications within a decade; definitive evidence within "20 to 30 years," she said Finding water on other celestial bodies is key to determination

"I think we're going to have strong indications of life beyond Earth within a decade, and I think we're going to have definitive evidence within 20 to 30 years," NASA chief scientist Ellen Stofan said Tuesday during a panel discussion on water in the universe.

"We know where to look. We know how to look," she said. "In most cases, we have the technology, and we're on a path to implementing it. And so I think we're definitely on the road."

NASA released a graphic noting that scientists have found evidence or indications of water on a number of celestial bodies, including the dwarf planet Ceres and Jupiter's moon Europa.

The Hubble Space Telescope has been key to the discoveries, NASA said in a news release.

"Scientists using NASA's Hubble Space Telescope recently provided powerful evidence that (Jupiter's moon) Ganymede has a saltwater, sub-surface ocean, likely sandwiched between two layers of ice," the agency noted.

There are some caveats involved, of course. NASA isn't talking about intelligent alien civilizations from the Alpha Quadrant; it's referring to microorganisms.

"We are not talking about little green men," Stofan said at the panel. "We are talking about little microbes."

Still, former astronaut John Grunsfeld said it's an exciting time -- and he thinks it's just a matter of time before we find life outside our solar system as well.

"I think we're one generation away in our solar system, whether it's on an icy moon or on Mars, and one generation on a planet around a nearby star," he said.

NASA has selected UT Arlington as one of four U.S. institutions to develop improved methods for oxygen recovery and reuse aboard human spacecraft, a technology the agency says is crucial to "enable our human journey to Mars and beyond."

NASA's Game Changing Development Program awarded $513,356 recently to the UT Arlington team. UT Arlington and three other teams are charged with the goal of increasing oxygen recovery to 75 percent or more.

Principal investigators on the UT Arlington project are Brian Dennis, associate professor of mechanical and aerospace engineering in the College of Engineering; Krishnan Rajeshwar, distinguished professor of chemistry and biochemistry in the College of Science; and Norma Tacconi, a research associate professor of chemistry and biochemistry.

They will design, build and demonstrate a "microfluidic electrochemical reactor" to recover oxygen from carbon dioxide that is extracted from cabin air. The prototype will be built over the next year at the Center for Renewable Energy Science and Technology, CREST, at UT Arlington.

"At the end of this 15 month Phase I project, we will demonstrate the prototype to NASA officials. If we are selected to move to Phase II, we plan to build a full-scale unit. We hope the technology will be flight tested on the International Space Station sometime in the future," Dennis said. "That's what we're really excited about and what we'll be aiming for."

Dennis said the design uses water and carbon dioxide as reactants and produces oxygen and hydrocarbon gases, such as methane. The gases can be vented into space and the oxygen is used for breathing.

"We have developed a nanocomposite electrode that speeds oxygen evolution at lower potential. That basically means it can produce more oxygen in a shorter time with less power and less reactor volume," said Dennis. "This is important since power on a spacecraft is limited because it comes from solar panels and spacecraft capacity also is limited. Things should be as compact and lightweight as possible."

Current methods of oxygen recovery used on the International Space Station, or ISS, achieve only about a 50 percent recovery rate. A better recovery rate means less oxygen needs to be stored and would free up precious cargo space on prolonged missions. With current technology, a trip to Mars would take about eight months, though scientists are working to shorten that time.

NASA's MAVEN Probe Hits Milestone

ABC Breaking US News | US News VideosCopy

NASA's MAVEN orbiter has completed its 1,000th lap around Mars, where it has been stationed for the past few months studying the Red Planet's upper atmosphere.

MAVEN, an acronym for the Mars Atmosphere and Volatile EvolutioN, became acquainted with Mars on Nov. 16 and ever since then has been orbiting the Red Planet trying to help scientists unlock some of the mysteries of Mars.

A high-altitude dust cloud and an aurora stretching deep into the Martian atmosphere have been two of the biggest mysteries MAVEN has observed during its time in orbit.

Since the probe has only been at work for four months, researchers said it remains unclear if it the dust cloud is temporary or a long-lasting phenomenon.

Mars' two moons, Phobos and Deimos, may be the possible culprits for the clouds, according to NASA. Other possibilities include a collection of dust from the atmosphere or particles carried by solar wind away from the sun.

NASA said the aurora was likely caused by energetic particles from the sun. The particles were able to strike deeper into Mars' atmosphere since the Red Planet lost its protective magnetic field billions of years ago.

"The spacecraft and instruments continue to work well," Bruce Jakosky, MAVEN's principal investigator, said in a statement. "Were building up a picture of the structure and composition of the upper atmosphere, of the processes that control its behavior, and of how loss of gas to space occurs."

NASA satellite sees a rooster in Tropical Cyclone Solo

Tropical Cyclone Solo looks like a rooster in visible and infrared imagery taken from NASA's Aqua satellite on April 10. Solo formed in the Coral Sea and is giving several islands something to crow about, because it has triggered watches already in Solomon Islands.

In the Solomon Islands today, April 10, a tropical disturbance watch was in effect for Rennell and Bellona, Temotu, Makira, Central, Guadalcanal and Malaita. For additional information visit the Solomon Islands Meteorological Services website at: http://www.met.gov.sb/. There are currently no warnings in effect for New Caledonia, but because Solo is expected to move toward the island, warnings are expected. For additional forecast updates in New Caledona, visit the Meteo France web page: http://www.meteo.nc/cyclone/phenomene-en-cours.

On April 10, when Aqua passed over the Southwestern Pacific Ocean, two instruments aboard gathered data on the newborn tropical cyclone. In visible imagery from the MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard Aqua, the center of the storm was circled by powerful thunderstorms, and a band of thunderstorms extended from the southeast out from the storm to the northeast, resembling a neck and head of a rooster. Another band of thunderstorms wrapping into the center from the northwest to the northern quadrant of the storm resembled a feathered tail.

The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite saw cloud top temperatures as cold as 210 kelvin (-63.1F/-81.6C) in powerful thunderstorms circling Solo's center and in bands of thunderstorms east and northwest of the center. Previous NASA research has shown that thunderstorms that high (and that cold) have the ability to generate heavy rainfall.

On April 10 at 1500 UTC (11 a.m. EDT), Solo's maximum sustained winds had already reached 45 knots (51.7 mph/83.3 kph). It was centered near 16.4 south latitude and 160.6 east longitude, about 484 nautical miles (557 miles/896 km) northwest of Noumea, New Caledonia. It is moving to the south at 13 knots (15 mph/24 kph) and is expected to turn to the southeast.

Solo's winds are expected to peak near 55 knots (63.2 mph/102 kph) on April 11, before weakening as a result of increasing vertical wind shear when it interacts with a deep mid-latitude trough (elongated area) of low pressure and cooler sea surface temperatures. The Joint Typhoon Warning Center expect those two factors to dissipate the storm by April 14.

From space, Tropical Cyclone Joalane's beauty is beyond compare. NASA's Aqua satellite captured a near-visible image of the storm moving east of Rodrigues Island in the Southern Indian Ocean.

On April 10 at 09:20 UTC (5:20 a.m. EDT), the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument aboard NASA's Aqua satellite captured a beautiful image of Tropical Cyclone Joalane that showed a tightly wound tropical cyclone, still at hurricane-strength. Strong thunderstorms circled the cloud-filled eye and extended in a band of thunderstorms south of the center.

At the same time from Aqua, another instrument called the Atmospheric Infrared Sounder, or AIRS, gathered temperature data on the storm using infrared light. The AIRS instrument revealed that the thunderstorms circling the eye and in a band south of the center were high in the troposphere with cloud top temperatures as cold as 210 kelvin (-63.1F/-81.6C). Previous NASA research has shown that thunderstorms that high (and that cold) have the ability to generate heavy rainfall.

As Aqua passed overhead, Tropical Cyclone Joalane's maximum sustained winds were near 75 knots (86 mph/139 kph). Joalane's eye was centered near 18.2 south latitude and 66.3 east longitude. That put the center of the storm about 247 miles (397.5 km) east of Rodrigues and 595 miles (957.5 km) east of Port Louis, Mauritius. Rodrigues Island is about 348 miles (560 kilometers) east of Mauritius.

Joalane was generating rough seas with maximum significant wave heights to 30 feet (9.1 meters). As a result, there was a "Strong wind and high wave warning" in effect for Rodrigues Island. According to the Mauritius Meteorological Services, the Lemongrass weather station on the island had received 15.6 mm (0.6 inches) of rainfall since April 9, and the Advanced Canon weather station received 14.3 mm (0.5 inches). For updates, visit: http://metservice.intnet.mu/cyclone-bulletin-french-rodrigues.php

The Joint Typhoon Warning Center (JTWC) forecast calls for Joalane to move in a southerly direction over the next several days and weaken. JTWC expects the storm will become extra-tropical by April 14.
