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

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Sunday evening, heading due east over the Atlantic Ocean to deliver the Intelsat 35e communications satellite into orbit 32 minutes later.

NASA’s Transiting Exoplanet Survey Satellite has arrived at the Kennedy Space Center in Florida for final testing, fueling and attachment to a Falcon 9 launcher for liftoff in mid-April, a delay of nearly one month to allow SpaceX additional time to prepare the rocket for the mission.

This is the pre-launch news conference held Dec. 2 at NASA’s Kennedy Space Center for liftoff of the Orbital ATK commercial Cygnus cargo ship aboard a United Launch Alliance Atlas 5 rocket for the International Space Station.
