2009年7月12日 · The International Space Station (ISS) requires stores of Oxygen (O2) and Nitrogen (N2) to provide for atmosphere replenishment, direct crew member usage, and payload operations. Currently, supplies of N2/O2 are maintained by transfer from the Space Shuttle.

Space Shuttle retirement in 2011 removes the primary source of N2 and O2 for ISS. NASA’s replacement for the Space Shuttle for O2/N2 logistics is termed the Nitrogen Oxygen Recharge System (NORS). There are 4 main elements in NORS: – Recharge Tank Assembly (RTA) - A transportable tank assembly

2009年7月12日 · The International Space Station (ISS) requires stores of Oxygen (O2) and Nitrogen (N2) to provide for atmosphere replenishment, direct crew member usage, and payload operations. Currently, supplies of N2/O2 are maintained by transfer from the Space Shuttle.

Stores of Oxygen and Nitrogen are maintained on the ISS in two locations. The first is in the High Pressure Gas Tanks (HPGTs) located around the Airlock module. There are currently three Oxygen HPGTs and two Nitrogen HPGTs. A final HPGT will be delivered on STS-134, but will be maintained as an on-orbit spare.

2023年2月22日 · The original ISS design called for High Pressure Gas Tanks (HPGTs) to be delivered by the shuttle. With the cessation of shuttle flights, a system called Nitrogen Oxygen Resupply System (NORS) was installed.
