Live coverage: Debut flight of Astra’s satellite launcher scrubbed
Astra was gearing up for the first orbital test flight of its small satellite launcher, named Rocket 3.0, from Alaska on Monday, but officials scrubbed the launch after detecting a problem with a guidance, navigation and control system in the final minute of the countdown. Poor weather at the launch site also prevented liftoff over the weekend on the first of two missions under the auspices of DARPA’s Launch Challenge.
