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

The next three-man crew to launch on a Soyuz rocket — comprising two Russian cosmonauts and a veteran NASA astronaut — is training to have the International Space Station to themselves after their arrival at the orbiting research outpost in April, at least until new U.S. commercial crew ships enter service.

A Russian Progress cargo ship glided to a smooth docking with the International Space Station early Sunday, bringing more than 3 tons of supplies and equipment to the lab complex.

A Northrop Grumman Antares rocket launch April 17 from Virginia’s Eastern Shore marked the start of the 11th Cygnus resupply mission to the International Space Station.
