Mars may be home to some of the oldest volcanoes in the solar system. New evidence suggests the Red Planet has been home to volcanic activity for at least 2 billion years.
Opportunity celebrated her 13th birthday on Sol 4623 (January 24, 2017 PST). She spent it as she has most recent sols - heading south along the rim of Endeavour Crater.
The spacecraft, rockets and associated systems in development for NASA's Commercial Crew Program are critical links in the agency's chain to send…
Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA's Mars Reconnaissance Orbiter.
The presence of water on ancient Mars is a paradox. There's plenty of geographical evidence that rivers periodically flowed across the planet's surface.
An orbital manoeuvres was performed on Mars Orbiter Mission (MOM) spacecraft to avoid the impending long eclipse duration for the satellite.
Opportunity is located on the rim of Endeavour Crater, heading south along the rim.
Microbes that rank among the simplest and most ancient organisms on Earth could survive the extremely thin air of Mars, a new study finds.
Scientists used NASA's Curiosity Mars rover in recent weeks to examine slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud.
Opportunity is located on the rim of Endeavour Crater, heading south along the rim.
The crew has been selected, and research studies confirmed for the 2017 mission of the University of Hawai?i at Manoa's Hawai?i Space Exploration Analog…
Opportunity is located on the rim of Endeavour crater, heading south along the rim.
Impact craters expose the subsurface materials on the steep slopes of Mars. However, these slopes often experience rockfalls and debris avalanches that keep…
Three-dimensional subsurface images are revealing structures within the Martian polar ice caps, including previously obscured layering, a larger volume of…
NASA's Mars Odyssey orbiter, which has been in service at Mars since October 2001, put itself into safe mode - a protective standby status - on Dec.
NASA engineers temporarily powered down most of the Mars Odyssey orbiter's systems earlier this week after an anomaly was detected.
