What Do Animals Need To Survive On Mars

As NASA prepares to transport astronauts to Mars in the future, scientists are looking for new ways to help them survive.

Chris Bricklayer, a geneticist and associate professor from Cornell University in New York, has come up upwardly with a new idea to genetically change human cells with Dna from micro-animals known as tardigrades to aid astronauts endure the long distance flight to Mars.

Tardigrades, commonly known as water bears, are a blazon of eight-legged micro-animal. They were get-go discovered by a German zoologist in 1773; only evidence from fossils shows that this living creature tin can exist dated back at least 530 meg years.

Dissimilar other bears, water bears are tiny, just measuring around 0.5 millimeters. Nigh of time they tin can only be observed nether a microscope.

For astronauts going to Mars, one major problem is high radiation exposure. Water bears could assist solve this problem.

The organisms can survive in farthermost atmospheric condition without any protection, and that includes infinite. In 2007, some dried upwardly h2o bears were sent to space past scientists. After 10 days of exposure to high radiation and a vacuum environs, scientists rehydrated the water bears and plant that they were still live. Afterward researching, the scientists discovered that at that place is a poly peptide in water bear'due south torso known as Dsup that protects them from the radiation. As a result, the scientists have called water bear's Dna as a genetic source.

Past transferring this power of the water bears to astronauts, it is possible they could survive nether loftier radiation in the space.

H2o bears, every bit one of the hardiest living creatures in the world, take played an important role in many areas of scientific research. Mayhap this tiny animal can assistance astronauts survive space in the future.

Micro world

People often find it difficult to understand the presence and office of microbes in their daily lives. They are hard to run across, merely they are everywhere. In this series, CGTN focuses on some of the smallest organisms in nature, and explores how these powerful organisms can either salvage or destroy us.
