Mars' mantle may be more complicated than previously thought. In a new study published today in the Nature-affiliated journal Scientific Reports, researchers at LSU document geochemical changes over time in the lava flows ...
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. 26, while remaining in communication with Earth.
Long before the space age, Earthlings were already in hot pursuit of life on Mars, using primitive telescopes and even psychic mediums to seek evidence of sentient beings.
Researcher Don Hood from LSU and colleagues at collaborating universities studied an unusual region on Mars—an area with high elevation called Thaumasia Planum. They analyzed the geography and mineralogy of this area they ...
The NASA spacecraft that was launched 15 years ago this week carried the name 2001 Mars Odyssey and the hopes for reviving a stymied program of exploring the Red Planet.
True to its purpose, the big NASA spacecraft that began orbiting Mars a decade ago this week has delivered huge advances in knowledge about the Red Planet.
Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.
Next week, a visual and infrared camera designed at Arizona State University will pass 60,000 orbits of the Red Planet.
In June 2015, Mars will swing almost directly behind the sun from Earth's perspective, and this celestial geometry will lead to diminished communications with spacecraft at Mars.
