I had almost forgotten about these guys. Designed to last 90 days and going for 6 yrs.
Out of the missions I think spirit got the short end of the stick. The roughest terrain, the worst weather, but yet still kept going.
Enjoy your nap Spirit, it's well earned.

In 1873, the British somewhat refined the idea, by taking the intestine out of the goat first.
