Lazy Orbit is a simple KSP2 mod for settings a vessel's orbit altitude. Open the GUI with ALT+H, select a body and an altitude, and press Set Orbit. Great for testing and modding, don't use it for anything nefarious!
First you need to patch KSP2 using the Space Warp mod loader, you can download that here: https://github.com/X606/SpaceWarp/releases
Then you need to place the extracted 'LazyOrbit' mod folder here:
