I feel this article should andwer the question of why there was even a need to fit a separate OMS instead of using the main engines to perform its functions.--[[User:Cancun|Cancun]] ([[User talk:Cancun|talk]]) 11:50, 9 August 2020 (UTC) |

This should be redirected in the opposite direction. There is no reason for caps. Ksnow 09:33, 7 July 2006 (UTC)Ksnow[reply]
Criticism_of_the_Space_Shuttle_program#Costs says "The toxic propellants used for the OMS/RCS thrusters required special handling, during which time no other activities could be performed in areas sharing the same ventilation system. This increased turn-around time" - Rod57 (talk) 22:26, 16 April 2017 (UTC)[reply]
Hello fellow Wikipedians,
I have just modified one external link on Space Shuttle Orbital Maneuvering System. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Space Shuttle Orbital Maneuvering System → Orbital Maneuvering System – Unnecessary disambiguation, as "Orbital Maneuvering System" is enough and more widely used than "Space Shuttle Orbital Maneuvering System". Requesting to withdraw the nomination because of the unanimous opposition. Soumyabrata (talk • subpages) 17:52, 22 January 2020 (UTC)[reply]
The figures, despite from seemingly reliable sources, don't add up.
Isp of 316 s | ve of 3100 m/s | ve = Isp*g0 |
dv | 300 m/s | |
Orbiter dry mass | 78,000 kg | |
Orbiter wet mass, or gross take-off weight | 100-110,000 kg | depending on source |
OMS fuel capacity | 21,660 kg | |
Payload | 29,500 kg |
This means:
wet mass | 129,000 kg | dry mass + payload + fuel |
dry mass | 59,000 kg | wet mass - payload - fuel |
dv | 565-750 m/s | dv = Isp * g0 * ln(m0/(m0-fuel)), for m0=129 and 100 tons, respectively |
What am I missing?
