The hatches between the International Space Station and the newly arrived Soyuz MS-22 spacecraft officially opened at 3:34 p.m. EDT. The arrival of three new crew members to the existing seven people already aboard for Expedition 67 temporarily increases the station’s population to 10. NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin joined Expedition …

Launch controllers have reached the replenish phase of liquid hydrogen loading operations for the interim cryogenic propulsion stage of the Space Launch System rocket and are continuing operations to load liquid oxygen into the upper stage. Teams are moving into operations to conduct a pre-pressurization test, in which engineers will bring the core stage liquid …

The Space Launch System’s core stage liquid hydrogen tank is now full and is being replenished as some of the supercold propellant boils off. Since resuming liquid hydrogen fast fill operations, the rate of the hydrogen leak at the tail service mast umbilical quick disconnect has remained within allowable rates. The core stage liquid oxygen …

NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin on the Soyuz MS-22 spacecraft docked to the International Space Station at 1:06 p.m. EDT. Coverage of hatch opening will air at 3:30 p.m. on NASA Television, the NASA app, and the agency’s website. Once on station, the trio will join Expedition 67 Commander Oleg Artemyev, …

Fast fill continues for the Space Launch System (SLS) rocket’s core stage liquid hydrogen (LH2) tank at a reduced pressure as teams monitor the area where the hydrogen leak was detected. Fast fill is complete for the core stage liquid oxygen (LOX) tank and engineers have completed the engine bleed test, which flows supercold LH2 …

Teams have resumed the flow of liquid hydrogen into the core stage after warming up the quick disconnect, or interface where the fuel feed line connects to the rocket, to reseat the connection as part of their troubleshooting plan to fast fill the propellant.

NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin are safely in orbit on the Soyuz MS-22 spacecraft after launching at 9:54 a.m. EDT from the Baikonur Cosmodrome in Kazakhstan (6:54 p.m. Baikonur time).  The Soyuz will dock to the space station’s Rassvet module at 1:11 p.m. About two hours after docking, …

Launch controllers have detected a hydrogen leak in a cavity in the tail service mast umbilical and have stopped flowing the propellant to the rocket while they troubleshoot the issue. Engineers will warm up the quick disconnect, or interface where the fuel feed line connects to the rocket, to attempt to reseat it.

Fast fill is underway for the Space Launch System (SLS) rocket’s core stage liquid oxygen (LOX) tank. Next, teams will transition from slow fill to fast fill for the liquid hydrogen (LH2) tank and initiate, or “kick start,” the engine bleed, which will begin flowing supercold LH2 to start cooling the four RS-25 engines down …

NASA TV coverage now is underway for the launch of a crewed Soyuz spacecraft to the International Space Station with NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin. The Soyuz MS-22 spacecraft will launch from the Baikonur Cosmodrome in Kazakhstan at 9:54 a.m. EDT (6:54 p.m. Baikonur time). Launch and docking activities …
