Surprised they don't have a computer do this.

They do, Dragon 2 docking is fully automated. The manual controls are a backup.

Did they get approved for full auto? Last I looked, only Kurs-equipped were allowed, everyone else got moved with Canadarm.

I've flown enough "flight assist off" in Elite Dangerous so this worked exactly like I expected it to :)

I hope someone makes a game like Elite Dangerous without care for actual gameplay, and even more realism. For example, with FA off in ED, there's still a speed limit that varies from ship to ship.

It is quite difficult to control with the mouse. It's basically impossible to kill rotation or velocity along a given axis. So one ends up with bang-bang control, constantly oscillating around the target. I am also somewhat horrified to learn that manual flight might be like this to, through the touchscreen[0]. Although there do appear to be some joysticks the astronauts can use, so hopefully this is just training fo…

RCS is always bang-bang, bang-bang means you input like PWM or PDM for rate and not like a throttle or a yoke for force.

I think the thrusters are a bit too powerful even at fine mode and numbers needs more precision.

This shows the value of training and realistic simulations. The first time I gave this a go, I completely failed. If I had really been in space the mission would have failed and potentially lives lost. But I learnt a lot and the next attempt was successful. The reality is that on-the-job training is best where the cost of failure is low. But where failures are costly or dangerous simulations are incredibly useful.

You can control it with the keyboard too, though that's not in the help. For rotation control use the numeric keypad, for translation the QWEASD region (and maybe ZXC). Experiment a bit since I don't know exactly which key does what.

It's still bang-bang control, that's the nature of RCS thrusters, but the keyboard makes it easier than the mouse.

much easier with the keyboard controls - wasd + qe and 8456 + 79

This is pretty cool! But I found little challenge in this simulation. Basically just correct your roll, pitch and yaw, then steer towards the target. Slow down at the end.

The easter eggs are fun though!

This was a lot of fun, on the first attempt had no idea even what the controls did and of course failed. But on the second go was able to get it all lined up and dock perfectly. Ready for NASA.
