"Russian specialists are continuing to look at the data and discussing what may have triggered the leak." "The cause of this leak not known at this time," NASA spokesperson Rob Navias said during live commentary. 21 to deliver the two cosmonauts and NASA astronaut Frank Rubio to the space station and was due to return to Earth size months later. The Soyuz spacecraft launched to the space station on Sept. 15 GMT) as cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing to exit the space station for a 7-hour spacewalk outside the station. Russia's space agency Roscosmos has called off a spacewalk by two cosmonauts at the International Space Station today after an apparent coolant leak on a Soyuz MS-22 crew capsule spewed coolant around its docking port on the orbiting lab. The coolant leak appears as frozen white mist around the spacecraft.

"During engine start, the fluid then flows to the engines for ignition. Flow into the catch tank is one of several parameters used to determine that the fluid has been properly bled into the system."Ī clogged ground filter reducing the flow to a TEA-TEB catch tank caused the issue and that filter has been replaced. SpaceX and NASA found a problem with ignition fluid, called triethylaluminum triethylboron or TEA-TEB, that sparks the oxidizer for the engines to turn on. 27) to the International Space Station (ISS) had been called off 2.5 minutes before T-0 due to a ground-system issue, but NASA said the issue has been addressed.
