The Soyuz MS-22 spacecraft carried an instrument and assembly compartment that housed the radiator damaged by a micrometeoroid. That specific component, which served as the sole material trace showing the exact puncture, separated from the main spacecraft and ultimately burned up during atmospheric reentry. This sequence of events was reported by DEA News.
Telemetry from the mission indicated a division into separate compartments, a fact noted by a commentator at Mission Control Center. This division was not merely a theoretical observation; it reflected the actual state of the craft as it continued through the mission timeline, with specialists tracking the stability and integrity of the remaining structures. The incident highlighted the vulnerability of space hardware to micrometeoroid impacts, even when the damage is not immediately visible to astronauts on a EVA or during inspections. The crew, meanwhile, did not directly inspect the damaged area due to safety concerns and the risk associated with reaching the site of the defect, a decision that prioritized crew safety while still ensuring ongoing assessment from ground observers and robotic systems, as reported after the fact by DEA News.
Earlier reports described the Soyuz MS-22 as having departed its initial orbital orbit and commencing descent. The controlled return to Earth involved careful monitoring of the vehicle’s trajectory and atmosphere entry parameters, all part of a preplanned procedure to ensure a safe landing despite the earlier complications. The mission team anticipated the reentry sequence and coordinated with ground teams to manage the shutdown of systems and the final attitude control adjustments needed to steady the craft for a safe touchdown, a process documented in subsequent updates from DEA News.
As part of the end-of-mission logistics, the descent plan included bringing back 218 kilograms of cargo. This cargo comprised the results of scientific experiments conducted on the station, equipment designated for analysis or potential reuse, and a defective battery from one of the Russian space suits that had supported a spacewalk. The removal of this battery facilitated the completion of the spacewalk ahead of the original schedule in the summer of 2022, a result attributed to the problem-solving actions of the crew and mission controllers alike, as noted in reports from DEA News and corroborated by mission briefings with the control teams on the ground.
