The 4-year old MAVEN mission will start making elliptical orbits closer to Mars' surface and prepare for its role as a future data-relay system for NASA's upcoming Mars 2020 rover.
NASA's MAVEN mission is investigating the mystery of how ancient Mars went from being a wet world to the cold, dry desert it is now. The MAVEN (short for Mars Atmosphere and Volatile Evolution) probe will investigate the Red Planet's thin atmosphere, searching for signs of how the planet became what it is today.

A new type of aurora has been spotted on Mars, and thieving streams of solar wind may be to blame, a new study shows.
NASA's Planetary Science Division Director, Jim Green, talks to the MAVEN mission's Principal Investigator Brice Jakosky and NASA's leading Mars scientist, Michael Meyer.
Dust storms that take over the Martian globe play a key role in promoting gas escape from the Red Planet's atmosphere, according to a new study.
A strong solar storm recently sparked a whole-planet aurora on Mars more than 25 times brighter than any seen before on the Red Planet, researchers say.
The annual Perseid meteor shower may be great, but it's got nothing on the brief sky show that Comet Siding Spring gave Mars in October 2014.
On Oct. 14, 2014 the Sun blew off a coronal mass ejection (CME) and was detected by the Solar and Heliospheric Observatory (SOHO) and other NASA/ESA probes.
Metal detected in the sky of Mars may come from meteors streaking through the Red Planet atmosphere, a new study finds.
Mars is dry as a bone today, but the Red Planet once had raindrops bigger than the ones we're used to here on Earth, a new study suggests.
NASA's MAVEN spacecraft has spotted iron, magnesium and sodium ions — electrically charged atoms — high up in the Red Planet's atmosphere over the past two years, a new study reports.
Close call! NASA's Mars-orbiting spacecraft shifted course this week to avoid a future collision with Mars' dark moon Phobos.
NASA's newest Mars orbiter has now been on the job for two Earth years, investigating how the Red Planet lost its atmosphere in the ancient past.
The first detailed look at Martian "nightglow" has been revealed, thanks to the work of NASA's newest Red Planet orbiter.
The red planet could provide insight into how the atmospheres are stripped off of distant, comet-like exoplanets.
A bombardment of asteroids on a once-icy ancient Mars may have created vast oceans of liquid water, which persisted for 200 million years.
