How does it have enough Delta-V to get into that distant of an orbit? Is it able to maneuver to different orbits and inclination? Is it able to return to earth?

How does it have enough Delta-V to get into that distant of an orbit? Is it able to maneuver to different orbits and inclination? Is it able to return to earth? Or, is it more of a satellite than a “plane”? This is my first time learning about this space plane, so apologies if my questions are naive.

- DocTomoe 2y agoIt has been to space several times, and there are photos and videos of it returning, shuttle-style on a runway. By carefully timing boosting burns at different points in the orbit, you can change the orbit to become highly inclined - go prograde at the periapsis, and your raise the apogee. From the image, I guess they are in a Molniar orbit [1]. [1] https://en.wikipedia.org/wiki/Molniya_orbit https://en.wikipedia.org/wiki/Molniya_orbit
- brylie 2y agoWow, thanks for sharing! I've never heard of Molniya orbit. Very interesting indeed.
- appointment 2y agoThis flight was launched with a Falcon Heavy, that is why it has more energy to reach high orbit than the previous launches with an Atlas V booster. When you are in a highly eccentric orbit (meaning the point in the orbit farthest from Earth (apogee) is much higher than the lowest point (perigee)) like this one there are several maneuvers you can do to significantly change your orbit with relatively little energy. The article describes some of the things they are testing. A small breaking burn at apogee will lower the perigee into the upper atmosphere and they can then do aerobreaking (use atmospheric drag to lose energy) to slow down enough to land.
- brylie 2y agoThanks for the great response! It's been a while since I played KSP, and I completely forgot about the apoapsis maneuvers :-) As an aside, it's sad about KSP2. We need a good, open-source space simulator in the spirit of KSP, which has incredible enthusiasm in the modding community.
