That's damn impressive! Especially using the gravity assists that way. I rather assumed we just needed the rover to be able to land & return under its own steam - you might have hit some kind of super-Val-level there...

Hahaha, Thanks 
I would not be able to make it back without the gravity assist. At the end, I only had 8m/s dv left. I used too much fuel climbing up the mountains

How do we earn it? by doing the challenge?

Here's my Primary Level entry.  Bill needed to get to Minmus really fast.  As in, under 3 hours from launch to the surface.  The engineers said, "No problem."  Bill managed to safely reach the surface of Minmus in 2 hours, 32 minutes, 11 seconds.

Just after liftoff.  The lower stage is powered by a bunch of Vector engines.  A lot of them.

Flight profile is basically launch when Minmus is overhead, then burn straight for it.  When the DV remaining is equal to my speed, I stop burning and coast.  I leave myself a little DV  to correct for errors.

Coasting to Minmus at about 6,000 m/s.  DV counter says I should have enough to get stopped at Minmus.

Slowing down.

Close to touchdown.

Landed.  Total flight time- 2 hours, 32 minutes, 11 seconds.

 

Decided to go fast, because I had really enjoyed doing a KSP1 challenge by @physius a few months ago.  Here's a link to that challenge:

My best time in KSP1 was just a little under 2 hours, but that isn't even close to the time some other players achieved.
