(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19.
On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away—which would be like a comet passing about 1/3 of the distance between Earth and the Moon.
(PhysOrg.com) -- Scientists at Arizona State University's Mars Space Flight Facility are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a new dust storm that has erupted on the ...
(Phys.org) -- NASA's Mars Odyssey spacecraft has successfully adjusted its orbital location to be in a better position to provide prompt confirmation of the August landing of the Curiosity rover.
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.
(Phys.org) —Eighth graders didn't have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning's ...
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.
(Phys.org) —NASA's Mars Reconnaissance Orbiter, which has overhauled understanding of the Red Planet since 2006, has passed 200 terabits in the amount of science data returned. The data returned by the mission alone is ...
(PhysOrg.com) -- By the middle of next week, NASA's Mars Odyssey orbiter will have worked longer at Mars than any other spacecraft in history.
