![]() Details vary slightly (antenna(s), probe cores, swivel/reliant/skiff, optional separatons on the boosters), but it's proven useful enough for 100+ launches in my careers.įrom that 120 km Ap/72 km Pe orbit, it was a simple matter to rendevous with each bit of space debris, dropping the first one to aerobrake, restoring a stable orbit, then docking and landing the last bit of space debris. Here is an example, using my usual low Kerbin orbit recovery rocket. Originally posted by andylaugel:Please excuse the 3 posts in a row, but I do find this topic interesting. When I separate the second stage I just take control and fly it back into the atmosphere, while my satellite goes on its merry way. Unforunately, KSP doesn't seem to like two unmanned control modules on the same craft. I was hoping I could avoid going that route. It should not be too difficult to put together a small unmanned probe with a grappling hook and enough fuel to reenter the atmosphere with whatever it has attached. The second stage could end up going anywhere. ![]() I tried using bigger boosters, but after a second or two of firing in the desired direction they don't really have any control. That is usually enough to slow the second stage so that it will eventually deorbit in one or two orbits.įor higher orbits (above 100 km) something else is required. ![]() I placed small boosters on them so when I separate the second stage the boosters fire in retrograde. When putting satellites into orbit between 80 km and 100 km I have no problem with the second stage re-entering the atmosphere. If you've done a gradual gravity turn, it shouldn't take too much more dV for your final stage to circularize your orbit. The atmosphere is 70 km high, but I tend to aim for 45 km for aerobraking. Watch your trajectory from the map screen, and drop your second stage before your Pe gets too high. Originally posted by andylaugel:Okay, if you want to design a ship that doesn't leave behind space debris with its second stage, then there is a simple way of doing it. For LKO rendevous like this, it helps to know right-clicking a maneuver node toggles its mode, and the '+' button in the new configuration advances the maneuver an orbit. I then completed the burn, getting a 72 km Pe.įrom that 120 km Ap/72 km Pe orbit, it was a simple matter to rendevous with each bit of space debris, dropping the first one to aerobrake, restoring a stable orbit, then docking and landing the last bit of space debris. No space debris generated during the launch. I waited, and then used up my last droppable stage with 350 m/s left on that burn, discarding it while the Pe was still below ground level. I then planned the circularization burn, which the navball told me would take 37 seconds. I burned from launchpad, nosing down gently to the east until my Ap was 120 km at 2 minutes 20 seconds away. I don't claim to be the most efficient pilot, but here is how it went. I launched one of these in my most recent career to remove 2 pieces of space debris left over from before I got the Klaw for crew rescues.
