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

Working under physical distancing requirements and other precautions against the coronavirus pandemic, range teams at Cape Canaveral are preparing for launches of Atlas 5 and Falcon 9 rockets from neighboring pads this weekend.

Four unidentified Russian military satellites rode a modified Soyuz booster into orbit Wednesday from a remote space base north of Moscow.

The mission, dubbed USSF-124, was the eighth National Security Space Launch using a SpaceX Falcon 9 rocket. Liftoff occurred at the start of a four-hour launch window that opened at 5:30 p.m. EST (2230 UTC) on Wednesday.
