Talk:Quest Joint Airlock

Needs updating
needs updating - states that something will happen in April 2006. Scatterkeir 21:48, 9 September 2006 (UTC)


 * I suspect it also needs updating as the airlock was installed and put into service in July 2001 and yet this article claims "The airlock is designed to contain equipment that can work with both types of spacesuits, however, it is currently only able to host American spacewalks because the equipment necessary to work with Russian space suits has not been launched yet." 14 years later, are we still waiting for the fittings or whatever so that Orlan space suits can be used in this airlock? --Marc Kupper&#124;talk 04:07, 27 September 2015 (UTC)

We could say when it was first used by astronauts, and when the Russian/Orlan equipment was fitted, and used. - Rod57 (talk) 19:17, 16 February 2022 (UTC)

What ports and hatches
Can spec section have details of ports and hatches. It has CBM on one end, to mate to ISS. Is the EVA exit hatch also based on, and as wide as, a CBM ? (lloks smaller),and what are dimensions of the IV hatch between the two segments ? - Rod57 (talk) 23:41, 16 February 2022 (UTC)

Specification - diameter - of what ?
Article says "diameter 4.4 m" but presumably this is of the equipment lock without any attached HP gas tanks. - Rod57 (talk) 10:42, 7 July 2021 (UTC)

How shipped
Was Quest shipped up in Shuttle with the two EVA tool boxes attached ? or were they attached later ? - Rod57 (talk) 10:42, 7 July 2021 (UTC)

How much gas lost on each EVA

 * How much gas (mass) is lost on each EVA ? Is entire airlock exhausted when hatch opens or has gas from airlock been compressed into tanks before hatch opens ?
 * Even Homes in Space Need a Door says "most" saved : "Air loss is further reduced by pumping most of the air in the lock back into the ISS before the astronauts begin their EVA." and "the remaining air in the Crewlock (about 5 psi or 345 mbar) is vented overboard "
 * SPCE says 70% of air in crew lock is saved. - Rod57 (talk) 18:47, 16 February 2022 (UTC)


 * How many EVAs can the 4 attached tanks cope with ? - Rod57 (talk) 10:42, 7 July 2021 (UTC)

More on the camp-out process - does it avoid the need to pre-breathe pure oxygen

 * Does the camp-out process described, avoid the need to pre-breathe pure oxygen ?
 * makes it sound like the camp-out replaces the 10 minutes exercise (and 50 minutes at reduced pressure), in the normal pre-breathe routine ? - Rod57 (talk) 14:03, 16 February 2022 (UTC)


 * Do the astronauts normally sleep during the camp-out ? (Yes, says another article)
 * Is the oxygen percentage increased when the pressure is reduced during the camp-out ?
 * Why was camp-out replaced by the light exercise procedure ?
