68 Soyuz Launch/Dock: 68S successfully launched at 8:54 AM CT this morning from the Baikonur Cosmodrome. Roscosmos cosmonauts Sergey Prokopyev and Dmitry Petelin launched alongside NASA astronaut Frank Rubio, who is participating on his first spaceflight to the Space Station. The trio docked to Mini-Research Module 1 at 12:07 PM CT beginning their six-month Space …
New Crew Enters Station and Begins Six-Month Mission
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 …
ICPS Liquid Hydrogen in Replenish, Teams Moving Ahead with Pre-Press Test
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 …
Liquid Hydrogen in Replenish, Teams Move Ahead with ICPS Loading
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 …
Three New Crew Members Dock Soyuz Crew Ship to Station
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, …
Artemis Cryogenic Test: Core Stage LH2 Underway; LOX Fill and Engine Bleed Test Complete
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 …
Liquid Hydrogen Filling Operations Resume
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.
Astronaut, Two Cosmonauts Launch to Join Station Crew
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, …
Hydrogen Leak Detected During Slow Fill Operations
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.
