The processing area for the Nitrogen Oxygen Recharge System (NORS) for the International Space Station, is in view in the high bay of the Space Station Processing Facility (SSPF) at NASA's Kennedy Space Center in Florida, on May 16, 2019. NORS are tanks that are used to fill the oxygen and nitrogen tanks that supply the needed gases to the station’s airlock for spacewalks and also are used as a secondary method to replenish the atmosphere inside the space station. The center is celebrating the SSPF’s 25th anniversary. The SSPF was built to process elements for the space station. Now it is providing support for current and future NASA and commercial provider programs, including Commercial Resupply Services, Artemis 1, sending the first woman and next man to the Moon, and deep space destinations including Mars.

Inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on June 25, 2021, commercial off-the-shelf air tanks – normally used by divers – are filled with breathing air for use on the International Space Station. Using expendable air tanks for this purpose increases the efficiency of supplying air to the orbital laboratory. It also will supplement the reusable Nitrogen Oxygen Recharge System (NORS) tanks that NASA currently uses.

Technicians prepare to unpack and inspect a Nitrogen/Oxygen Recharge System (NORS) tank inside the Space Station Processing Facility high bay at NASA’s Kennedy Space Center in Florida on July 16, 2020. The NORS tanks and their support fixtures are designed to connect to the International Space Station’s existing air supply network to refill the previous generation of tanks installed during construction of the space station. These reusable tanks measure 3 feet long and 21 inches in diameter, and weigh about 200 pounds when filled. Once onboard, the tanks will be used to fill the oxygen and nitrogen tanks that supply the needed gases to the space station’s airlock for spacewalks. They could also be used to replenish the atmosphere inside the station. The NORS tanks will launch to the station later in the year on a commercial resupply mission.

iss052e004913 (June 19, 2017) --- The aurora and the night sky above Earth’s atmosphere are pictured from the space station. A portion of the station’s solar arrays and a pair of nitrogen/oxygen recharge system tanks are pictured in the foreground.

iss049e002733 (09/14/2016) --- Expedition 49 crew member and NASA astronaut Kate Rubins works with a Nitrogen/Oxygen Recharge System (NORS) tank aboard the International Space Station. The tanks are designed to be plugged into the station's existing air supply network to refill the crew’s breathable air supply. Each tank is pressurized up to 10,000 pounds per square inch to giving the station an atmosphere of nitrogen and oxygen like that of Earth, the system provides the pure oxygen astronauts breathe before beginning a spacewalk. The gases also are used in the station's ammonia-based cooling system and for other secondary uses.
