Here’s my submission 
Didn’t turn out quite as ambient as I expected, but it was quite fun to make.
The unaltered sample is some of the quake on Mars, low rumbling the whole time. There’s a repetitive click and bass (pretty buried) that’s chopped up from the Mars rover. The synth sound is a SCW from the solar winds on Mars that I turned into a synth on the Deluge. Rest of the sounds come from my Nord Drum
[Creatively, I stole this progression from Bill & Miles]
