Spacesuits optional for 'water bears'

Tiny invertebrates are the first animals to withstand the vacuum and radiation of space.

It's one small step for water bears, one giant leap for animal-kind. Tiny animals called tardigrades — better known as water-bears — have become the first animals to survive the cruel vacuum, intense cold and radiation of space without a spacesuit.

  • The pup fish in Death Valley may be another specimen that could similarily survive. They go into hybernation during the summer months in heats that reach over 100F. They get a good dose of UV.

  • The Genome of these animals, water bears and others such as pup fish and microbes living in extreme conditions should be sequenced. It would reveal a lot about disease and environmental resistance that would be useful for human health
