Meteorite may represent 'bulk background' of Mars' battered crust
NWA 7034, a meteorite found a few years ago in the Moroccan desert, is like no other rock ever found on Earth. It's been shown to be a 4.4 billion-year-old chunk of the Martian crust, and according to a new ...
Curiosity rover finds active, ancient organic chemistry on Mars
(Phys.org)—NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by ...
Martian meteorite yields more evidence of the possibility of life on Mars
(Phys.org) —The finding of a 'cell-like' structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are published ...
Meteorites yield clues to Martian early atmosphere
(Phys.org) —Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published ...
Team uncovers secrets of Mars' birth from unique meteorite
As NASA prepares to launch a new Martian probe, a Florida State University scientist has uncovered what may be the first recognized example of ancient Martian crust.
Research says Mars had oxygen-rich atmosphere 4000 million years ago
Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4000 million years ago—well before the rise of atmospheric oxygen on Earth ...
Remaining Martian atmosphere still dynamic
(Phys.org) —Mars has lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate. Rover team members reported diverse findings today ...
First meteorite linked to Martian crust
After extensive analyses by a team of scientists led by Carl Agee at the University of New Mexico, researchers have identified a new class of Martian meteorite that likely originated from the Mars's crust. ...
Curiosity rover finds clues to changes in Mars' atmosphere
