| High-Pressure Gas Tanks |
| Overview |
|
In addition to the airlock, the High-Pressure Gas Assembly also is being delivered by Atlantis. The assembly includes four high-pressure gas tanks -- two oxygen and two nitrogen. Each tank is just over 3 feet (.9 meter) in diameter. A meteor debris shield and a multi-layer insulation blanket to protect them from the harsh elements of space cover each tank. For the STS-104 flight, the tanks are on an adaptor that is mounted on the double Spacelab pallet in the shuttle cargo bay. The tanks and adapters also were designed and built by Boeing at MSFC. The Russian Service Module "Zvezda" has been supplying these gases for the ISS. The High-Pressure Gas Assembly will augment the Service Module gas re-supply system.
