STS-104 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Atlantis. Its primary objectives were to install the Quest Joint Airlock and help perform maintenance on the International Space Station. It launched on 12 July 2001 at 09:04 UTC, and returned to Earth without incident after successful docking ...
The Quest Joint Airlock is the primary airlock for the International Space Station. Quest was designed to host spacewalks with both Extravehicular Mobility Unit (EMU) spacesuits and Orlan space suits. The airlock was launched on STS-104 on July 14, 2001. It was attached to the starboard CBM of the Unity during STS-104. The four external HP ...
The STS-88 Space Shuttle mission followed two weeks after Zarya was launched, bringing Unity, the first of three node modules, and connecting it to Zarya. This bare 2-module core of the ISS remained uncrewed for the next one and a half years, until in July 2000 the Russian module Zvezda was launched by a Proton rocket, allowing a maximum crew ...
The spacewalkers change a grapple fixture so the airlock can be used as a base point for the arm, broke torque on bolts that secure the airlock and radiator to Rassvet, removed launch restraints from the radiator, vented nitrogen jumpers, replaced a retainer on Strela 2 with one that has a stop, and transferred a MLM outfitting work platform ...
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
The 7A crew will install, activate, and perform the first space walk from the Joint Airlock. The Joint Airlock will enable crews to perform space walks in either United States or Russian spacesuits while recovering over 90 percent of the gases that were previously lost when airlocks were vented to the vacuum of space.
The plate is located on the back of the PCBM's outboard flange by a pair of dowel pins (5). As the bolt nudges the nut during acquisition, motion of the nut is constrained by tabs on the Floating Washer (6) inside the plate's rectangular hole and by a Spherical Washer (7). A Castellated Nut (8), locked with a Cotter Pin (9), holds the stack ...
The arm was also necessary to attach a new airlock to the station on the subsequent shuttle flight, mission STS-104. The final component of the Canadarm is the Mobile Base System (MBS), which was installed on board the station during the STS-111 flight.
