The Progress's cargo bay, besides the XC4 sports car, also contained some space exploration equipment. It was scheduled to remain in space for 24 hours before being remotely commanded to return, with an expected landing at Ulanha Mountain Airport.
During this period, the ground center was to conduct complete tests on the Progress's cabin airtightness, air circulation system, and other aspects.
The H1 type space shuttle has two configurations: the Progress is the cargo version with a smaller crew cabin that can accommodate a maximum of 4 people. The rear half is widened to carve out a larger cargo bay. The second craft, the Unity, is the manned version, able to carry up to 6 people with a much more spacious crew cabin. The trade-off is a smaller cargo bay that can only accommodate 2100 kilograms of cargo.
