The air leak rate in the Russian Zvezda module of the International Space Station has halved after the crack in the intermediate compartment was sealed with tape, according to the crew's communication with Earth, broadcast by NASA.

The air leak rate in the Russian Zvezda module of the International Space Station has halved after the crack in the intermediate compartment was sealed with tape, according to the crew's communication with Earth, broadcast by NASA.

On Friday, cosmonaut Anatoly Ivanishin informed the Moscow-based Mission Control Centre that the pressure in the compartment had declined by 52 mm Hg to 681 mm Hg over 11.5 hours, while the leak rate had fallen to 4 mm per hour from 7-9 mm per hour.

The cosmonaut noted that the pressure continued to fall, but at a slower pace. He also suggested trying US patches to seal the crack.

Russian space agency Roscosmos earlier told Sputnik that the air leak posed no threat to the crew.

Earlier, Russian cosmonauts sealed the source of the air leak. On Thursday night, they once again closed the hatch to the "leaking" compartment to control pressure.

Thomas prepares for Time in space
Houston TX (ESA) Oct 14, 2020
ESA astronaut Thomas Pesquet trains for the Time experiment at NASA's Johnson Space Center in Houston, USA ahead of his Alpha mission to the International Space Station in 2021. This European experiment on the International Space Station investigates the hypothesis that time subjectively speeds up in microgravity and was first run in space in 2017. Whether an activity takes seconds or hours depends on your point of view. For astronauts living off-planet and experiencing roughly 16 sunrises a ... read more
