NASA will host a media teleconference at 9 a.m. PST (noon EST) on Friday, Nov. 7, to provide initial science observations of comet C/2013 A1 Siding Spring's close flyby of Mars and the impact on the Martian atmosphere.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, Mars Reconnaissance Orbiter (MRO), and a radar instrument aboard the European Space Agency's Mars Express spacecraft provided the first close-up studies of the comet that originated from the distant, outer reaches of our solar system.
Briefing participants include:
- Jim Green, director, Planetary Science Division, NASA Headquarters, Washington
- Nick Schneider, instrument lead for MAVEN's Imaging Ultraviolet Spectrograph, University of Colorado, Boulder
- Mehdi Benna, instrument scientist for MAVEN's Neutral Gas and Ion Mass Spectrometer, NASA Goddard Space Flight Center, Greenbelt, Maryland
- Don Gurnett, lead investigator on the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument on Mars Express, University of Iowa, Iowa City
