Astra launch just scrubbed due to a problem with the water deluge system on the pad. They'll try again tomorrow.
In other news, SpaceX made a successful 150m hop with its prototype starship SN5 test article at Boca Chica on Tues. There's a nice youtube video of the hop here
. There were some spectacular explosions of earlier test items this spring. Nice to see it actually fly, although it looks like someone's grain silo flew the coop! The engine used here is the new Raptor
, which burns methane rather than kerosene.
