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

SpaceX is seeking approval to add up to 30,000 more satellites to its Starlink broadband network, on top of 12,000 spacecraft already authorized by U.S. government regulators, according to filings submitted to the International Telecommunication Union.

A sophisticated combat-ready U.S. military missile warning satellite moved to its launch pad at Cape Canaveral Space Force Station Saturday on top of a United Launch Alliance Atlas 5 rocket, ready for liftoff Monday afternoon.

United Launch Alliance teams began stacking an Atlas 5 rocket inside a vertical hangar at Cape Canaveral Monday in preparation for an early February launch with the Solar Orbiter spacecraft, a joint U.S.-European probe that will take the first pictures of the sun’s poles.
