How long did it take to prepare it for the next flight
Criticism_of_the_Space_Shuttle_program 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)

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)
 * Oppose for now, will keep track of the discussion. The page indicates that the system was Space Shuttle specific, so using the present name seems a more accurate encyclopedic descriptor. Randy Kryn (talk) 03:42, 23 January 2020 (UTC)
 * Oppose as the name "Orbital Maneuvering System" is used in relation to other spaceflight systems, like the ESPA and Buran. Also keeps the title in line Space Shuttle Solid Rocket Booster. -- Netoholic @ 10:59, 23 January 2020 (UTC)
 * Oppose Overly generic proposed title that could potentially exist on any spacecraft.ZXCVBNM (TALK) 21:05, 24 January 2020 (UTC)

Data mismatch dv/isp/mass
The figures, despite from seemingly reliable sources, don't add up.

This means:

What am I missing?

Why even have the OMS?
I feel this article should answer the question of why there was even a need to fit a separate OMS instead of using the main engines to perform its functions.--Cancun (talk) 11:50, 9 August 2020 (UTC)
 * eg. Main engines had no propellant after the External Tank was jettisoned. - Rod57 (talk) 12:39, 27 September 2020 (UTC)

Other things to add
Other things to add - eg ref the OMS workbook :
 * propellants could be cross-fed between OMS pods
 * OMS propellant could feed the RCS
 * OMS pods had separate He tanks for the OMS and RCS systems
 * OMS pods had N2 tanks, for post-firing engine purge, (and maybe other things)
 * OMS engines could not be used under 70,000 ft (or nozzles might collapse)
 * OMS engines could gimbal (and had two redundant sets of gimbaling actuators)
