When I watch videos of probes landing on Mars after cutting the parachutes off, they show the lander doing final orientation adjustments before touching down.
The engines don't seem to have a vectoring range, but I don't know if that's an omission of the animation or it reflects reality.
So I am wondering how does the probe correct its pitch, yaw and roll.
note: My question is about attitude control of recent Mars landers post-parachute, not about various animations that are out there. There have been many landing schemes on Mars, it's not necessary to go through every one, but if it's possible to focus on the more recent ones that would be most helpful.
They are operated in pulse mode to arrest the craft’s horizontal and vertical velocity and also keep it in the proper orientation for landing, achieved through differential pulsing of the thrusters to actively control the pitch, yaw and roll of the lander.
but it's not at all clear how that actually works.
