How Does the Tiny Waterbear Survive In Outer Space?
DevotedSkeptic sends this excerpt from SmithsonianMag:
"The humble tardigrade, also known as a 'waterbear' or 'moss piglet,' is an aquatic eight-legged animal that typically grows no longer than one millimeter in length. Most tardigrades (there are more than 1,000 identified species) have a fairly humdrum existence, living out their days on a moist piece of moss or in the sediment at the bottom of a lake and feeding on bacteria or plant life. In 2007, a group of European researchers pushed the resilience of this extraordinary animal even further, exposing a sample of dehydrated tardigrades to the vacuum and solar radiation of outer space for 10 full days. When the specimens were returned to earth and rehydrated, 68 percent of those that were shielded from the radiation survived, and even a handful of those with no radiation protection came back to life and produced viable offspring. How do the little tardigrades survive such a harsh environment? Although amateur tardigrade enthusiast Mike Shaw recently made waves by postulating that the animals may be equipped to survive in outer space because they originally came from other planets, scientists are certain that the creatures developed their uncommon toughness here on earth."
I meant that in a nice way.

Tardigrade Captain: Okay over there, bring the ship down in that clearing, it looks like there's some specimens there on that asphalt path. ... apparently dead organic material ... ... ... but sir, this colony may be lacking light speed travel but our sensors show a plethora of cultural phenomena -- aggregates of which exist right here in this very metropolis! ...
*the Tardigrade craft lands in Time Square and the well armed two meter tall Tardigrades disembark*
Tardigrade Captain: Oh, for the love of Ursa Major! How ugly these specimens turned out! Look at that one!
*the Tardigrade captain gestures toward an Earth female with her jaw agape*
Tardigrade Captain: Ewww, what is this on top of them?
*the Tardigrade captain reaches for the girls hair with his second set of appendages while the first set rubs saliva down his mouth onto his chest and his tertiary set scratches himself*
Tardigrade Officer: *runs a device over the woman* Some sort of fibrous material sir
*the Tardigrade captain withdraws his appendages in terror*
Tardigrade Captain: Oh for fuck's sake, another experiment ruined. Gross. GROSS. All of them just gross as all hell! Alright, everybody back on the ship, you know the drill, take off and nuke 'er from orbit
Tardigrade Officer: But
Tardigrade Captain: You know Jerry, it's always something with you, isn't it? 'Mew mew mew, this civilization has eliminated all evil. Blah blah blah this civilization is one million years old, isn't that worth something?' Now this is the 174th failed experiment we've checked up on and I
*just then an advertisement for Here Comes Honey Boo Boo blares across the Times Square display -- the stupefied Tardigrades watch*
Tardigrade Officer: I'll push the button this time.
My work here is dung.
I hear you. And most worrisome is that we may have endowed them with super powers by exposing them to cosmic radiation in outer space!
- "What's the status on those wriggly buggers?"
- "Tardigrades? Well, sir, against all odds and expectations, some of them managed to survive. They're even breeding!"
- "Really? Even the ones exposed to cosmic radiation?"
- "Even the ones exposed to cosmic radiation, yes."
- "Wow! They're even more resilient than we thought!"
- "You could even say, indestructible..."
- "Amazing."
- "Sir, what should we do with them now?"
- "We bring them back to Earth and watch them breed and see what happens from there...
- "Aye! Aye! What could possibly go wrong?"
