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

A sharp-eyed French military surveillance spacecraft is set for launch aboard a Soyuz rocket Monday from French Guiana into a 300-mile-high orbit, where it will collect the highest-resolution imagery ever produced by a European reconnaissance satellite.

NASA astronaut Mark Vande Hei and two Russian cosmonauts will ride a Soyuz ferry ship to the International Space Station early Friday, the first step in a record crew rotation requiring two launches and two landings with four different spacecraft in just three weeks.

For the second time in seven weeks, SpaceX, Telesat and SSL teamed up for a commercial satellite launch from Cape Canaveral early Monday, this time successfully deploying into orbit a high-power telecom payload developed in a joint venture with a Hong Kong-based company.
