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

Debris from SpaceX’s Falcon 9 rocket booster returned to shore in Southern California late Monday after it tipped over on touchdown on a landing platform in the Pacific Ocean following liftoff with a ocean study satellite.

Two days after lifting off aboard a SpaceX Falcon 9 rocket from the Complex 40 launch pad at Cape Canaveral Air Force Station, a commercial Dragon supply ship loaded with more than 4,800 pounds of supplies and experiments arrived Sunday at the International Space Station. Capture of the robotic cargo craft occurred at 5:57 a.m. EST (1057 GMT).

Managers aborted liftoff of a commercial Antares cargo launcher Saturday when an aircraft strayed into restricted airspace near the rocket’s planned flight path east from Virginia’s Eastern Shore.
