As of tomorrow morning, there will be five space vehicles parked at the International Space Station.
The SpaceX Dragon space freighter, the Northrop Grumman Cygnus resupply ship, and Russia’s Soyuz MS-13 and MS-15 crew ships are already there. The Russian Progress 74 that launched Friday at 4:34 a.m. is expected to dock to the Pirs compartment on the station’s Russian segment at 5:38 a.m. Monday, Dec. 9.
NASA TV and the agency’s website will provide live coverage of Progress rendezvous and docking at 4:45 a.m.
Dragon and Progress are two of four robotic spaceships that currently fly resupply missions to the ISS. The other two are Japan’s H-II Transfer Vehicle and Cygnus, which is operated by Virginia-based Northrop Grumman.
