1
00:00:00,590 --> 00:00:06,350
Astronauts could benefit from the survival skills of one of Earth's toughest animals.

2
00:00:06,350 --> 00:00:11,700
Tardigrades are found on every continent.

3
00:00:11,700 --> 00:00:17,340
The microscopic organisms can tolerate a range of extreme environments.

4
00:00:17,340 --> 00:00:22,610
But how do they respond to life in space?

5
00:00:22,610 --> 00:00:29,300
Astronauts will help conduct a study aboard the International Space Station.

6
00:00:29,300 --> 00:00:34,340
The tiny creatures will live in special hardware developed at NASA's Ames Research Center.

7
00:00:34,340 --> 00:00:40,100
DNA analysis will be used to understand how tardigrades adapt to the stresses of spaceflight.

8
00:00:40,100 --> 00:00:45,250
The results may lead to future treatments that promote astronaut health...
