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

A European Vega rocket deployed six commercial satellites in orbit, including a new Airbus-built eye-in-the-sky for high-resolution Earth-imaging, on a successful launch from French Guiana on Wednesday night after two of the last three Vega missions failed.

Taking off and landing in the middle of the night at Cape Canaveral, a SpaceX Falcon 9 rocket successfully delivered a Dragon supply ship to orbit for the International Space Station as the launcher’s first stage booster swooped to a spectacular touchdown.

Something went wrong with a Russian Progress cargo spacecraft moments before it deployed into orbit Tuesday on the way to the International Space Station, and investigators are analyzing whether the stricken supply ship may have lost control after a botched separation from its Soyuz rocket booster.
