Endurance

OK, I guess this is technically off-topic - but a quote from a NASA press release this week really caught my attention:

This week, during the 779th Martian day of what was originally planned as a 90-Martian-day mission…

That’s right - the two rovers are stll carrying out good science, having already functioned for well over 8 times their planned mission duration.

I recall that NASA was willing to consider the mission a success if they got 30 days science out of each rover.

If 30 days are “success”, then what are 779 days (and counting)?

I should be so lucky as to work on a project that successful!
