ESA’s Mars Express has returned new images of an elongated impact crater in the southern hemisphere of Mars. Located just south of the Huygens basin, it could have been carved out by a train of projectiles striking the planet at a shallow angle…
The moon was bombarded by two distinct populations of asteroids or comets in its youth, and its surface is more complex than previously thought, according to new results from NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft featured in three…
Orcus Patera is an enigmatic elliptical depression near Mars’s equator, in the eastern hemisphere of the planet. Located between the volcanoes of Elysium Mons and Olympus Mons, its formation remains a mystery.
Often overlooked, this well-def…
Research by a University at Buffalo planetary geologist suggests that generally accepted estimates about the geologic age of surfaces on Mars — which influence theories about its history and whether or not it once sustained life — could be way off. Funded by the National Aeronautics and Space Administration, the research eventually could overturn principles about the relative ages of different areas on the Red Planet that have not been questioned for nearly 20 years.
