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.
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.
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.
NASA has beefed up a process of traffic monitoring, communication and maneuver planning to ensure that Mars orbiters do not approach each other too closely.
This week 15 years ago, NASA launched a spacecraft with the name 2001 Mars Odyssey, and onboard was the Thermal Emission Imaging System (THEMIS), a multi-wavelength camera designed at Arizona State University.
NASA's next Mars space probe, a lander named InSight, is due to touch down on the Red Planet in September 2016 with a mission focused on the planet's internal properties. Its landing place has been chosen with help from a ...
A research team led by LSU Geology and Geophysics Assistant Professor Suniti Karunatillake reveals a spatial association between the presence of sulfur and hydrogen found in martian soil. The work by this multi-institutional ...
