Q&A with Keith Gendreau, principal investigator of the first X-ray space communications experiment (members only)

NASA’s small Lunar Flashlight spacecraft, sent to the moon last year to search for water ice deposits at the lunar south pole, will not be able to complete its science mission after a problem with the probe’s propulsion system.

A Soyuz rocket and Fregat upper stage lifted off Saturday from the Baikonur Cosmodrome in Kazakhstan, delivering 34 more satellites to orbit for OneWeb’s space-based Internet network in the company’s second launch this year.

SpaceX’s Dragon supply ship departed the International Space Station on Wednesday, fired rocket thrusters to brake out of orbit, and parachuted to a picture-perfect splashdown in the Pacific Ocean with approximately 3,461 pounds of experiment samples and equipment.
