Crew Dragon commander Mike Hopkins, pilot Victor Glover, and mission specialists Shannon Walker and Soichi Noguchi flew to the Kennedy Space Center on a NASA-chartered private jet Sunday, ready for a final week of training, refresher courses, and some time off before their launch to the International Space Station.

An electrical problem on SpaceX’s drone ship parked just off the coast of Cape Canaveral prompted SpaceX to scrub a Falcon 9 launch attempt early Friday, delaying the start of a resupply mission to the International Space Station by 24 hours.

Veteran Russian cosmonaut Oleg Kononenko, flanked by Canadian flight engineer David Saint-Jacques and NASA astronaut Anne McClain, launched toward the International Space Station at 6:31 a.m. EST (1131 GMT) Monday from the Baikonur Cosmodrome in Kazakhstan, the first crew launch for Russia’s space program since a Soyuz booster failure led to the emergency landing of a two-man crew in October. The Soyuz MS-11 spacecraft docked with the station at 12:33 p.m. EST (1733 GMT).
