In the Las Vegas slider, the Lake Mead before/after difference is startling.

I'm more intrigued at the increased green of the landscape at large, did the water supply actually improve to encourage more plant growth?

The diminishing quantities of blue stuff got put on the brown stuff to turn it into green stuff.

It seems like a lot of these government-owned space things last a lot longer than they're made for. There's Landsat, Spirit, Opportunity, Hubble, the Voyagers, et cetera. It seems to be a pretty steep curve - either they fail on launch or landing or very early, or they far outlast expectations. There seems to be little that meets expectations. I can see lots of failures - space stuff is hard - but why so many things exceeding it?

The engineering to get it to last a year probably isn’t significantly different from five years, etc.
