The information is now available on NASA’s online planetary data archive.

Undergraduate paves way for NASA Mars mission

Tabatha Heet, a junior earth and planetary sciences major and Pathfinder student, shows Ray Arvidson, earth and planetary sciences department chair, a potential landing site for the Phoenix mission to Mars.Earth and planetary scientists at Washington University in St. Louis are paving the way for a smooth landing on Mars for the Phoenix Mission scheduled to launch in August this year by making sure the set-down literally is not a rocky one. A team led by Raymond E. Arvidson, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, has been analyzing images taken from a NASA instrument to make sure that the Phoenix spacecraft lands in a spot on the Red planet’s northern plains that is relatively rock-free. Video included.

NASA spacecraft read layered clues to changes on Mars

NASA/JPL-Caltech/Univ. of Arizona.Polar layered deposits exposed in a scarp at the head of Chasma Boreale, a large canyon on Mars.Mars climate history, recorded in ice-rich deposits near the poles, on crater-wall cliffs and ancient sand dunes, is being revealed by a trio of NASA instruments now flying over and rolling across the planet, suggest Washington University in St. Louis researchers playing key roles in the mission.

Two other Mars missions heating up

The Mars Reconnaissance Orbiter (above) is poised to go into orbit around Mars in March, then spend about six months aerobraking to place the spacecraft in a low circular orbit by this fall.Two Mars orbiter missions — one from NASA, the other from the European Space Agency (ESA) — will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, providing international researchers with the first direct clues about the Red Planet’s subsurface structure. Roger Phillips, Ph.D., Washington University in St. Louis Professor of Earth and Planetary Sciences in Arts & Sciences, is participating in both the Mars Express (ESA) and NASA’s Mars Reconnaissance Orbiter (MRO) missions by lending his expertise in radar. Phillips says that the combination of the radars on the two missions will provide important and unique data sets that will directly map the structure of the upper portions of the interior of Mars.

Popular site sheds light on meteorites

Randy Korotev with a sample meteorite found in Siberia.The mysterious orb you find in your backyard that wasn’t there just the day before has to be a meteorite, right? Wrong. Overwhelmingly the chances are it’s a meteorwrong, says Randy Korotev, Ph.D., research associate professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis. He says that 998 out of 1,000 meteorites are from asteroids, one out of 1,000 is from the Moon, and one out of 1,000 is from Mars. Of the hundreds of meteorites that have been found in the United States, none has been a lunar meteorite, and only one has been a Mars meteorite.

Water detection at Gusev crater described

Map of life on Earth could be used on Mars

Carinne Blank has a method she uses to date ancient life forms that could be helpful for specimens from Mars.A geologist from Washington University in St. Louis is developing new techniques to render a more coherent story of how primitive life arose and diverged on Earth – with implications for Mars.

Despite hurdles, human missions to Mars are in the works

Mars Exploration Rover mission scientists remind us that the amazing success of the rovers *Spirit* and *Opportunity* is a harbinger for the day when humans inhabit the Red Planet.The major drawback to a human mission to Mars is preparing for the one to two years of radiation and microgravity exposure that astronauts must endure. While that is a large hurdle, enabling technologies are emerging that should be able to make this goal a reality over the next couple of decades, and America should go for it. That’s the theme of a report from NASA’s 2002 Astrobiology Academy appearing soon as a paper in Acta Astronautica.
