"Water Bears" First Animals to Survive Trip Into Space Naked
Adam Korbitz writes "New Scientist and Science Daily are reporting the results of an intriguing experiment in which scientists launched tardigrades or 'water bears' — tiny invertebrates about one millimeter long — into space onboard the European Space Agency's FOTON-M3 spacecraft. After 10 days in the vacuum of space, the satellite returned to Earth and the tardigrades were recovered. The tardigrades survived the vacuum just fine, but exposure to the Sun's ultraviolet radiation proved deadly for most of the water bears. However, some did survive. The tardigrades are the first animals to have survived such an experiment, a feat previously achieved only by lichens and bacteria."
After RTFA /shock, the focus seems to be not on the fact they survived in space but more the fact that they survived being dosed repeteadly with huge amounts of radiation, without any apparent damage to the DNA structure.
I don't see any reason why a lifeform that has evolved to survive in space should necessarily be better equipped to then survive elsewhere - any species that suddenly transitions from one environment to a vastly different one is going to have a hard time surviving. When a species adapts it doesn't necessarily keep all of its old abilities as well as the new ones, otherwise we'd all be able to breathe underwater!
which is totally what she said
Suggested list of headlines that do not suck:
"Tardigrades First Animals to Survive the Vacuum of Space"
"'Water Bears" First Animals to Withstand Exposure to Naked Space"
"First Animal to Survive the Vacuum of Space"
Come on, Timothy -- Naked tardigrades? I trust you can do better than that...
It should be noted that just becuase this species can SURVIVE exposure to space doesn't mean they can THRIVE in it.
This species is capable of entering a state of suspended animation that renders it rather resistant to extreme heat and cold, dehydration and hard radiation.
It's been a long time.
