Live coverage: Proton rocket launches with two U.S.-built satellites

Liftoff of a previously-flown Falcon 9 rocket from NASA’s Kennedy Space Center with a European-built television broadcast satellite has been pushed back from Saturday until at least next Wednesday night, officials said.

A SpaceX Falcon 9 rocket soared into orbit Monday from Cape Canaveral with nearly three tons of hardware and supplies for the International Space Station.

SpaceX scrubbed the first test launch of its huge new rocket Monday due to a frozen valve in the pressurization system on the 33-engine Super Heavy booster, delaying the widely-anticipated flight from South Texas until at least Thursday.
