The rate of air leaking from the hole increased around a week before the February 14 launch of the Progress MS-26 cargo spacecraft, which docked to the aft end of Zvezda. The hatch that connects the module to the ISS remained open for five days as the crew offloaded the cargo from Progress MS-26 onto the space station, but was closed shut afterwards.
NASA and Roscosmos are currently monitoring the leak and preparing to close the hatch to the service module when access is not required in order to minimize the amount of air lost and isolate the leak itself from the rest of the space station. If required, the space agencies are prepared to permanently shut off the hatch should the leak rate became unmanageable. The ISS would function normally, but there would be one less docking port for spacecraft delivering cargo to the space station.
