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

A commercial satellite to broadcast television programming to millions of homes in Brazil and a multipurpose communications craft to beam high-definition video and Internet signals across Indonesia are awaiting a half-hour ride into orbit on an Ariane 5 rocket Tuesday.

The SpaceX Dragon cargo ship loaded with supplies, crew provisions, new science experiments and an experimental expandable module for the International Space Station arrived Sunday morning for rendezvous, capture and berthing.

This will be the second hearing for the commercial astronaut, billionaire and entrepreneur following his first go around in April. This hearing is scheduled for Dec. 3 beginning at 10 a.m. EST (1500 UTC).
