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

A United Launch Alliance Delta 4-Heavy rocket is awaiting liftoff with a classified U.S. government spy satellite at Vandenberg Air Force Base’s historic Space Launch Complex-6, a picturesque rocket facility that was once intended to support launches of military astronauts and space shuttles.

The first launch of a Russian Proton rocket since June has been delayed until at least January to conduct additional checks on the three-stage booster and its Breeze M upper stage, Russian space officials said.
