Russian flight controllers have given up attempting to salvage a Progress cargo ship loaded with 3 tons of supplies and equipment intended for the International Space Station. Astronaut Scott Kelly, on board the lab for a year-long mission, said Wednesday the Progress will not be docking and instead will plunge back into the atmosphere.

The Starlink 17-5 mission will add another 24 broadband satellites to the company’s constellation of more than 8,100 currently in orbit. SpaceX is targeting liftoff from pad 4E at 9:26 a.m. PDT (12:26 p.m. EDT / 1626 UTC).

Boeing said Tuesday the first orbital test flight of its commercial crew capsule, named the Starliner, will be delayed until August “in order to avoid unnecessary schedule pressure” and give priority on the Atlas 5 rocket’s manifest to a U.S. Air Force communications satellite. NASA confirmed Wednesday that officials have approved an extension of the Starliner’s first crewed mission to last up to several months.
