Latest Geology of Mars Stories
New analysis of Mars' terrain using NASA spacecraft observations reveals what appears to be by far the largest impact crater ever found in the solar system.
Brown University researchers have found compelling evidence of thick, recurring glaciers on Mars, a discovery that suggests that the Red Planetâ€™s climate was much more dynamic than previously believed â€“ and could change again. Results are published on the cover of Geology magazine.
A new analysis of impact cratering data from Mars reveals that the planet has undergone a series of global volcanic upheavals. These violent episodes spewed lava and water onto the surface, sculpting the landscape that ESAâ€™s Mars Express looks down on today.
Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice.
Mars is showing scientists its older, craggier face buried beneath the surface, thanks to a pioneering sounding radar co-sponsored by NASA aboard the European Space Agency's Mars Express orbiter.
By ALICIA CHANG LOS ANGELES - A provocative new study of photographs taken from orbit suggests that liquid water flowed on the surface of Mars as recently as several years ago, raising the possibility that the Red Planet could harbor an environment favorable to life.
Liquid water has flowed on the surface of Mars within the past few years, leaving behind new deposits in gullies monitored by the now-lost Mars Global Surveyor. The results seem to boost the chances that Mars could harbour life.
European scientists have now used a high-resolution imaging spectrometer aboard the orbiting spacecraft Mars Express to construct a new picture of the planet's geologic history.
To learn if Mars ever supported life, researchers should look underground, a scientist presenting results of the Mars Express mission said at a conference this week.
Substantial quantities of liquid water must have been stably present in the early history of Mars. The findings of OMEGA, on board ESA's Mars Express, have implications on the climatic history of the planet and the question of its 'habitability' at some point in its history.
