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

NASA, United Launch Alliance and Air Force officials hold the pre-launch news conference for the Delta 2 rocket with the agency’s SMAP environmental satellite from Vandenberg Air Force Base on Jan. 27.

Something went wrong with a Russian Progress cargo spacecraft moments before it deployed into orbit Tuesday on the way to the International Space Station, and investigators are analyzing whether the stricken supply ship may have lost control after a botched separation from its Soyuz rocket booster.

These additional views of the Falcon Heavy’s maiden liftoff from the Kennedy Space Center, and landing of its two side boosters at nearby Cape Canaveral Air Force Station, come from locations across the Florida spaceport.
