Update and first images from NASA’s MAVEN spacecraft (Mars Atmosphere and Volatile Evolution), which is orbiting Mars.
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars, produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen, and carbon coronas surrounding the Red Planet, and yielded a comprehensive map of highly-variable ozone in the atmosphere underlying the coronas.
“All the instruments are showing data quality that is better than anticipated at this early stage of the mission,” said Bruce Jakosky, MAVEN Principal Investigator at the University of Colorado, Boulder. “All instruments have now been turned on — although not yet fully checked out — and are functioning nominally. It’s turning out to be an easy and straightforward spacecraft to fly, at least so far. It really looks as if we’re headed for an exciting science mission.”
