Time-lapse: The Falcon 9 and Crew Dragon roll to the launch pad (members only)

An impromptu repair job Thursday appears to have stopped a leak in a Russian Soyuz spacecraft docked to the International Space Station, and the crew was back on its normal schedule Friday carrying out research and making preparations for the arrival of a Japanese cargo ship next month.

The four astronauts will spend three to five days in a free-flier Dragon mission that will see them orbit over the north and south poles. The crew arrived in Florida on Monday for their final week of quarantine before launch.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Monday, heading due east over the Atlantic Ocean to deliver the Telstar 18 VANTAGE communications satellite into orbit around 32 minutes later.
