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

Virgin Orbit and Rocket Lab teams are gearing up for their first missions of the year in the coming days, with Virgin’s air-launched rocket set for its second demonstration flight and Rocket Lab’s Electron booster poised to launch a small German-owned communications satellite.

A twin-engine Northrop Grumman Antares rocket climbed into orbit Saturday from Virginia’s Eastern Shore carrying a Cygnus supply ship bound for the International Space Station with a compact electron microscope, a flame combustion experiment, a range of biological investigations, fresh cheese, fruit and vegetables for the research lab’s three-person crew.

With lingering uncertainty about when new U.S. commercial vehicles can regularly carry crews to the space station, NASA said Tuesday it will pay the Russian space agency more than $90 million for a round-trip ticket to the International Space Station on a Soyuz spacecraft later this year.
