Roscosmos to carry out ‘profound analysis’ to prevent future thermal system problems

According to Sergey Krikalev, executive director of Roscosmos for manned space programs, this is now the main task

MOSCOW, February 11. /TASS/. Russian state-run space corporation Roscosmos will perform a ‘profound analysis’ to make sure that thermal control systems of its spacecraft do not carry any systemic errors, Roscosmos executive director for manned space programs Sergey Krikalev said on Saturday.

"We need to carry out a profound analysis to make sure that similar systems do not experience the same problem during future launches," he said. "This is the main task that we are facing now."

According to the space official, experts will carefully examine launch preparation sequences, as well as materials and technologies used when the thermal control system was assembled. The same kind of analysis was carried out in the wake of a pressure leak from a radiator of the Soyuz MS-22 spacecraft.

"Making sure that this was not a systematic error of any kind is what matters most," Krikalev added.

A commission tasked with analyzing all possible causes of the breakdown began its work on Saturday.

A drop in pressure was detected aboard the Progress MS-21 freighter, which was expected to end its mission at the International Space Station (ISS) on February 18. The spacecraft has been isolated from the ISS. Roscosmos said the causes of depressurization were being investigated, and emphasized that it had no effect on either the docking of the Progress MS-22 cargo spacecraft to the ISS or the schedule of space activities aboard the ISS.
