The "Progress MS-29" cargo ship is undergoing a series of tests before its dispatch to the ISS. It will be checked for leaks.
The ship will be placed in a helium-air environment. This way, engineers will find out if there are any problems with the pneumatic-hydraulic systems of the ship and whether the compartments are airtight. "Progress MS-29" has already been transported to a vacuum chamber, but the tests have not yet started.
Note that last week, radio equipment was tested. A special anecoic chamber was used for this.
As a reminder, "Progress MS-29" will be launched from the Baikonur Cosmodrome on November 21. The ship was created to service orbital stations. It delivers cargo to the ISS, and it is also used to adjust the station's orbit.
