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

Seattle-based Spaceflight Industries has purchased a SpaceX Falcon 9 rocket for launch in 2017 with a mash-up of satellites in the first such commercial arrangement for a rideshare mission on a U.S. launcher, the company announced Wednesday.

A faulty support strut inside the Falcon 9 rocket’s second stage liquid oxygen tank likely broke free during a June 28 space station resupply launch, destroying the booster minutes after liftoff in a cloud of debris over the Atlantic Ocean, SpaceX chief Elon Musk said Monday.

The launch of a Japanese X-ray telescope and robotic lunar lander has been delayed to no earlier than August, and the launch schedule for another Japanese mission to return samples from a moon of Mars is in doubt as engineers investigate the failure of Japan’s first H3 rocket last month.
