Soyuz MS-22 spacecraft leaking coolant as seen on NASA TV livestream. December 14: Soyuz MS-22 spacecraft sprung a leak in external cooling loop of the service module. The leak was determined to be caused by a micrometeoroid impact. The spacecraft stayed docked as an emergency rescue vehicle but was deemed not viable for a normal crew return.
A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...
On 2 January 2004, a minor air leak was detected on board the ISS. [2] At one point, five pounds of air per day were leaking into space and the internal pressure of the ISS dropped from nominal 14.7 psi down to 14.0 psi, although this did not pose an immediate threat to Michael Foale and Aleksandr Kaleri, the two astronauts on board.
He instead logged 371 days in space following the discovery of a coolant leak coming from his original ride — a Russian Soyuz capsule — while docked to the orbiting outpost.
The incident follows recent coolant leaks from Russian spacecraft parked at the station. Those leaks were blamed on tiny meteoroids. The lab — named Nauku, which means science — arrived at the ...
Core plugs can also sometimes prevent freeze damage to the motor. During the early stages of the freezing of the engine coolant a freeze plug will sometimes burst or pop out, and thus allow the coolant to exit the engine, before it might expand within the engine during the freezing process and potentially crack the engine block.
