Q&A with George Ricker, principal investigator for the TESS mission (members only)

SpaceX launched a Falcon 9 rocket from Cape Canaveral Air Force Station at 6:24 p.m. EST (2324 GMT) Thursday with the U.S. military’s next GPS navigation satellite. The mission was delayed more than a month after a previous countdown was aborted seconds before liftoff.

NASA and Northrop Grumman are “suspending integration and testing operations” on the James Webb Space Telescope in response to the coronavirus pandemic, a decision that officials said is likely to delay the mission’s scheduled launch date in March 2021.

United Launch Alliance chief executive Tory Bruno spoke with Spaceflight Now’s Stephen Clark at the 32nd Space Symposium in Colorado Springs.
