Q&A with Tory Bruno, ULA’s chief executive

Continuing a dizzying series of rescheduled launches from Florida’s Space Coast, poor weather at the Kennedy Space Center forced SpaceX to keep a Falcon 9 rocket and 60 Starlink broadband satellites on the ground Monday. The Starlink launch is expected to be delayed until Thursday, after a pair of national security missions are set to blast off from Cape Canaveral Tuesday.

The revised Atlas 5 rocket firing order includes two national security missions this summer before launching NASA’s daring asteroid sampler mission in September as originally planned.

U.S. military officials said Tuesday the launch of the next satellite for the GPS navigation network — planned for April 29 on a SpaceX Falcon 9 rocket — has been delayed to no earlier than June 30 to avoid exposing launch crews to the COVID-19 viral disease. However, the next launch of the military’s X-37B spaceplane remains on track for liftoff in May on a United Launch Alliance Atlas 5 rocket, officials said.
