ESA’s Mars Express has spotted a rare case of a crater once filled by a lake, revealed by the presence of a delta. The delta is an ancient fan-shaped deposit of dark sediments, laid down in water. It is a reminder of Mars’ past, wetter climate.

The delta is in the Eberswalde crater, in the southern highlands of Mars. The 65 km-diameter crater is visible as a semi-circle on the right of the image and was formed more than 3.7 billion years ago when an asteroid hit the planet.

NASA Invites 150 Lucky Twitter Followers to Launch of Lunar Spacecraft

September 2, 2011 Leave a comment

NASA has invited 150 followers of the agency’s Twitter account to a two-day launch Tweetup Sept. 7-8. The Tweetup is expected to culminate in the launch of the twin lunar-bound GRAIL spacecraft aboard a Delta II rocket from Cape Canaveral Air Force Station in Florida.

The launch is targeted for 8:37 a.m. EDT on Sept. 8. The two GRAIL spacecraft will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail from crust to core. The mission also will answer longstanding questions about the moon and provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.

NASA will host a media teleconference at 1 p.m. EDT on Wednesday, Sept. 7, to discuss new observations about solar flares that can impact communication and navigation systems.

NASA’s Solar Dynamics Observatory, or SDO, is providing new data and images for scientists to better understand the sun’s dynamic processes, which can affect Earth. The spacecraft launched in February 2010.

The initial work of NASA’s Mars rover Opportunity at its new location on Mars shows surface compositional differences from anything the robot has studied in its first 7.5 years of exploration.

Opportunity arrived three weeks ago at the rim of a 14-mile-wide (22-kilometer-wide) crater named Endeavour. The first rock it examined is flat-topped and about the size of a footstool. It was apparently excavated by an impact that dug a crater the size of a tennis court into the crater’s rim. The rock was informally named “Tisdale 2.”
