Live coverage: Proton blasts off on return-to-flight mission

Ground crews took steps this week to prepare for the next Falcon 9 launch, set for no earlier than Jan. 30 with a telecom satellite for SES and the Luxembourg government, as SpaceX officials stressed their rocket was not to blame for the rumored loss of a mysterious U.S. government payload after liftoff Sunday.

A Soyuz rocket is scheduled for liftoff Friday from the Vostochny Cosmodrome, Russia’s newest launch site, with 33 satellites from 12 countries on-board to collect weather data and test new space technology.

A United Launch Alliance Delta 4 rocket lifted off from Cape Canaveral on Wednesday night with the U.S. Air Force’s eighth Wideband Global SATCOM communications satellite, lighting up the sky in these images taken from the nearby Kennedy Space Center press site.
