solved the problem, the rocket was very big and without enough reaction wheels or rcs it was evident that with so much speed it could not maintain its course. I have discovered that with small or medium rockets it is not necessary to have rcs or many reaction wheels since they only move with electricity. I don't know if it's true I just came to this conclusion

yes thank you all for your advice, on the third try i barely managed to land and i did a little jump which made my lander spin and crash (all kerbals are alive, well...i hope so) but i just have to practice and figure out where to start the engines to save deltav but still make a safe landing. There is only one other unknown: if I will be able to go back to Kerbin, the DeltaV is super tight and the image is very, very small, so if you can recommend an engine for this situation, that would be nice.

Basically what happened is that I braked to close an orbit in Dune and see if that made it easier for me to brake, when I started to have contact with the atmosphere the speed was around 1000ms. when I stopped having resistance I was going a little fast and neither the engines nor the parachutes (for emergencies) saved me and everything ended in an incredible explosion against the ground. I use "cheetah" motors for maximum efficiency during takeoff, the lander weighs about 30T in just necessities, plus it's the same one that should get me back to Kerbin

Yes, I made a new orbit but I added more aerodynamic surfaces and set a periapsis of 20km. This time it went well but I have to improve the landing. I did a burn at 1km height to reduce the speed since the motor I use is not very powerful and it can hardly lift-off

I tried with periapsis of 10km but the resulting speed reaching the lower atmosphere was very high (it ended very badly) the lander is quite small and I thought it wouldn't end up going very fast more or less like 750m/s and the speed before the descent was around 1000m/s

I also thought the same thing but the electrical load is full and the 3 "vector" motors have free gimbal. my rocket is similar to the Starship but without flaps and consists of 3 stages, it also has a reaction wheel to minimize the use of monopropellant or fuel in space maneuvers. I did a test flight of DeltaV for a mission to Duna, but this happens and affects orbit accuracy and wastes fuel.

I have a problem, when my rocket is about to reach a perfect orbit and leaves the atmosphere behind and enters the vacuum almost immediately, the SAS begins to lose control of the ship, this leaves it spinning around and around without stopping, of time to make my planned maneuver to orbit the rocket is too far from the maneuver point and this affects the entire orbit. Also, the rocket feels very unstable in a vacuum when I start the engines, help!

Im new in interplanetary travels and i sent multiple probes and satellites to Duna... and i will send my first crewed mission to the red planet. I want to know if the aereobraking is possible in Duna and how to get a succesfully braking.
