Decade-Old Rover Adventure Continues on Mars and Earth

Eighth graders didn’t have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning’s Channel One news in her Fredericksburg, Texas, classroom caught her eye.

“I wasn’t particularly interested in space at the time,” she recalled last week inside the spacecraft operations facility where she now works at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “I remember I was talking with friends, and out of the corner of my eye I noticed this thing bouncing and rolling on a red surface. I watched as it stopped and opened up, and it had this rover inside.” (more…)

Martian Crater May Once Have Held Groundwater-Fed Lake

PASADENA, Calif. — A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet’s early evolution.

The new information comes from researchers analyzing spectrometer data from NASA’s Mars Reconnaissance Orbiter, which looked down on the floor of McLaughlin Crater. The Martian crater is 57 miles (92 kilometers) in diameter and 1.4 miles (2.2 kilometers) deep. McLaughlin’s depth apparently once allowed underground water, which otherwise would have stayed hidden, to flow into the crater’s interior. (more…)

Carbon from Martian Meteorites Not Evidence of Life

The findings provide insight into the chemical processes taking place on Mars and will help aid future quests for evidence of ancient or modern Martian life.

Carbon in some Martian meteorites came from Mars but not from life on Mars, according to new research from an international team that includes a University of Arizona geoscientist.

Molecules containing large chains of carbon and hydrogen – the building blocks of all life on Earth – have been the targets of missions to Mars from Viking to the present day.

Scientists have disagreed about how the organic carbon found in meteorites from Mars was formed and whether or not it came from Mars. (more…)
