NASA Science Briefing: Comet Siding Spring at Mars

Lowell Observatory in Flagstaff, Arizona is famous as the place where dwarf planet Pluto was discovered by Clyde Tombaugh in 1930, but it has an illustrious 121-year-old record of astronomical research and discovery. After a 20-month-long restoration project, Lowell’s historic 24-inch Alvan Clark refractor is poised to reopen for public observing sessions.

NASA has released the first high-resolution aerial colour image of the Opportunity rover’s landing site on a sprawling Martian plain, where the airbag-cushioned robot fortuitously rolled into a Eagle Crater in January 2004, putting its scientific instruments face-to-face with a block of sedimentary rock that gave ground teams confirmation Mars was once a warmer, wetter, and habitable planet.

NASA’s longest-lived mission to Mars has gained its first look at the Martian moon Phobos, pursuing a deeper understanding by examining it in infrared wavelengths.
