If RCS propellent was not to be used until re-eentry anyways, why would they have not completed docking and then re-entered using the remaining propellant, as it was evidently sufficient enough to maintain attitude during re-entry? | |

| May 3, 2019 at 15:44 | comment | added | Organic Marble | It didn't have much to do with the earth's gravity (although that is what holds it in orbit). A spacecraft in orbit will accelerate (start to move or rotate) when a force pushes on it. It will continue to accelerate as long as the force acts on it. If the mass of the spacecraft suddenly gets smaller, the acceleration gets bigger. The famous equation F=ma describes this. In this case, the force was the jet firing. They couldn't stop the ship from accelerating because they couldn't shut the jet off. | |
| May 3, 2019 at 15:39 | comment | added | penguin99 | Why did the roll over continue for a really long time? Is it because the earth's gravity was causing it to revolve that way without any opposing friction? Like a never ending car drift on a smooth road? | |
| May 3, 2019 at 15:36 | comment | added | Organic Marble | Redundant in spacecraft design is not a bad thing. It simply means that there is a backup system. If the primary system never fails, the 'redundant' system may never be used. | |
