Q&A with Mark Mulqueen, Boeing’s space station program manager

SES has selected United Launch Alliance and SpaceX to launch up to five new commercial C-band communications satellites from Cape Canaveral in 2022 aboard Atlas 5 and Falcon 9 rockets, officials announced Wednesday.

The launch of a European Ariane 5 rocket was aborted moments after its main engine ignited Tuesday. The dramatic last-second hold was the first time an Ariane rocket launch was aborted after engine start since March 2011. Arianespace has not set a new target launch date for the mission, which will loft two U.S.-built communications satellites for Intelsat and B-SAT.

The U.S. Government Accountability Office has denied a protest filed by Sierra Nevada Corp. challenging NASA’s selection of competitors Boeing and SpaceX to build commercial human-rated space capsules to fly astronauts to the International Space Station.
