NASA Mars Orbiter Examines Dramatic New Crater

A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter on Nov. 19, 2013.

Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as [...]

Comet ISON Appears In Tact As it Plunges Toward Perihelion Next Month

NASA’s Hubble Space Telescope captured this image of Comet ISON on Oct. 9, 2013. The image suggests that the comet is intact, a good sign that it will survive perihelion next month when it dives to within one million miles of the Sun’s surface.

Much talk of Mars these days seems to focus almost exclusively upon the multi-faceted Curiosity rover, as it unravels the mysterious geological past of Gale Crater, or upon the Opportunity [...]

Four Decades After It Landed on the Red Planet, Mars 3 Found

NASA’s Mars Reconnaissance Orbiter has discovered what could be segments of the Soviet Union’s Mars 3 spacecraft, which disappeared on the Red Planet in 1971. Image Credit: NASA/JPL-Caltech

On May 28, 1971, the Soviet Mars 3 spacecraft blasted off from Baikonur atop a Proton-K rocket, just nine days after its sister probe Mars 2. [...]

NASA MRO Video Highlights Mars’ Dynamic Environment

NASA’s MRO mission has determined that the Red Planet goes through seasonal changes just like Earth does. The changes, however, are very different than what we experience on our home world. Image Credit: NASA/JPL-Caltech/Univ. of Arizona

A recent video compiled of imagery from NASA’s Mars Reconnaissance Orbiter (MRO) shows that—far from the dead planet [...]

Distant Mars Has Some Similarities to Hawaii, Curiosity Finds
