Gregory's Server@BenHouston3D looks like it is going incredibly fast when it smashes back into the earth!

@BenHouston3D @jamesjefferies Similar re-entry speed to Apollo and about 1.5x re-entry speed of a shuttle. I wouldn't fancy it myself. Strictly ground crew! @BenHouston3D @jamesjefferies The atmosphere will gradually slow it down. Apollo missions had similar reentry speeds.  @BenHouston3D @jamesjefferies Not sure they are doing that but aerobreaking seems an option to decrease apogee. A quick dive into the thinnest upper atmosphere can save a lot of delta v. And if time is no issue, you can repeat this as much as needed to decrease speed for safe (final) reentry. @jamesjefferies @BenHouston3D That's what retrorockets are for. They basically have to undo what the booster rockets did. |
@jamesjefferies Interesting, you are correct, according to the speed in the bottom left, it will be doing 10km/s when it comes back to earth. Maybe it does another gravity type encounter, this time with earth, that kills its forward speed? Probably information on this somewhere onlineβ¦
