I once got stuck on a blow-up-able tank and had to blow it up to unstick myself ^_^
I have all the upgrades I can get so far and a good 150k of each thing, except for element zero... so now, I still go and scan planets, but only quickly to see if there are anomalies or if the planet is rich or if it's heavy in element zero. So I can go through a solar system in a good minute or two if nothing good comes up.
