With lingering uncertainty about when new U.S. commercial vehicles can regularly carry crews to the space station, NASA said Tuesday it will pay the Russian space agency more than $90 million for a round-trip ticket to the International Space Station on a Soyuz spacecraft later this year.

A Falcon 9 rocket carrying the heaviest payload ever launched by SpaceX took off Monday morning from Cape Canaveral with 60 satellites for then company’s Starlink broadband network.

A day after a timing error caused it to enter the wrong orbit and miss its objective of meeting up with the International Space Station, Boeing’s unpiloted Starliner crew capsule prepared for its next major test Sunday, when it will plunge back into the atmosphere and target a predawn landing at White Sands Space Harbor in New Mexico.
