![]() Try to use the body drag and lift to slow your decent. Then, try to tilt your craft sideways so the side of it is facing your velocity vector. hopefully youre only going 500-800/ms at this point. Then, wait until youre in the thickest part of the atmosphere, and youre just seeing mach effects. It doesnt always work and kinda relies on luck, but try to come in as shallow as possible. I had something like this not too long ago. ![]() (apoaxis relatively high - some 150,000, deploy airbrakes after periaxis at 55,000, burn retrograde and slightly anti-radial at 60,000, turn prograde and airbrake again. ![]() If you want to really be sure, add A.I.R.B.R.A.K.E.S. When your speed drops below 400m/s open the parachute. Wait through all the flames and fancy effects, keeping the capsule retrograde (parachute tip back).ĥ. When about to enter the atmosphere, burn off the rest of your fuel (retrograde), drop the last stage, and rotate the capsule retrograde.Ĥ. Once your apoaxis is less than 200,000m (less is better) bring your periapsis to 45,000m.ģ. ![]() Allow several circles of the orbit, possibly performing some retrograde burns at periapsis to speed things up if you have spare fuel but aerobraking while less efficient is free.Ģ. On return enter an elliptical orbit that goes at some 48-55,000m periapsis, rather more than less. My guess is OP is opening too early, or possibly entering at a too steep trajectory.ġ. It seems an opened parachute is far less heat-durable than a closed one. The faster you go the higher your periapsis have to be. This 36km alt of periapsis is what works for me, but it depends from your speed. If you get to hot you need to go up, if you stop loosing horizontal speed then you need to go down, or make another orbit if you dont have enough deltaVs. You just have to use your engines (or to some degree shape of your craft) to adjust your vertical speed. The horizontal speed would be decreasing rapidly by the drag. This way you will reduce your vertical speed, so you won't be sinking into denser atmosphere. When your craft begin to overheat don't youse your engines to reduce your horizontal speed, burn upward instead. Before entering atmosphere set your periapsis to around 36km. Would they both get destroyed at same time ?Īlso how much deltaV do you have left ? You can use that deltaVs to help you a lot. Do you have one or more chutes ? If more than one, try deploying one as soon as you enter atmosphere, leave other as it is. Otherwise it would just blow up and disappear completely. I think that you get this message only if the chute is deployed. "parachute destroyed due to heat and drag". I try to remember to do a staging checklist before launching any vehicles (I simply had forgotten this time, and fortunately a cheap mistake that didn't wind up killing the mission) going over the major "oops" possibilities (like launch clamp releases before igniting the first stage - this is something that KSP usually does, and if not corrected, can easily destroy a mission on the pad). You can fix this by adjusting the atmospheric pressure it will deploy at as another poster above noted (I think you may be able to do this on the fly, but not sure - if not, you will have to wait for a rescue mission to come up and get your Kerbals and science out). Please note though, the parachute does not actually deploy until it goes below a certain atmospheric level, so it visually looks like the parachute is still packed, but by default it will deploy itself quite high up while you are still moving very fast, so it is instantly destroyed by the airspeed and heat if it has already been staged. My Duna probe wound up with the parachutes on the same stage as my rendevous (final) engine, so when I fired that engine to fine tune my Duna approach, it also deployed my parachutes (fortunately, my Duna entry was cool enough and slow enough that it didn't actually destroy my chutes, but if the same mistake had been made on a Kerbin re-entry vehicle, it would have been bye-bye parachutes at about 15000 ft). Sometimes KSP, particularly if you're adding and removing engines, makes mistakes in how it sets up staging.
