@pete Reminds me of an undergrad astro course I once took. Prof explains the US used to sterilize everything we sent to Mars, but it cost 10x as much since the whole probe had to then survive autoclave temps.
Meanwhile the USSR didn't do likewise for lack of funding.
As a result, there's now an agreement among the astro community, that no one *has* to sterilize anything bound for Mars as it's been "contaminated" at this point.
No idea if that's true, but the story stuck with me.
It was a bright cold day in April, and the clocks were striking thirteen. Welcome to 13 Bells, a respite from the commercial social media platforms.
