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

A Soyuz spacecraft carrying a three-man crew parachuted to the flat grasslands of Kazakhstan on Saturday, returning home from the International Space Station with cosmonaut Yuri Malenchenko, NASA astronaut Tim Kopra and British flight engineer Tim Peake.

SpaceX launched two Falcon 9 rockets in a span of a little more than four hours Friday, a record-setting day that began with the launch of 52 Starlink internet satellites from California and ended with the sunset liftoff of two SES television broadcast payloads from Florida.

Signs that a launch to the International Space Station is approaching are obvious this week at Cape Canaveral, with the Atlas 5 booster rocket beginning to take shape and the commercial resupply ship heading to its propellant depot.
