General News Thousands Of Water Bears May Be Stranded On The Moon

On the moon there may be thousands of tardigrades, also known as water bears, due to a space accident. 

Last April, the Israeli spacecraft Beresheet crashed into the Moon during a failed landing attempt. In doing so, he could have spread thousands of tardigrades on the lunar surface.

Beresheet was a robotic lander. It transported samples of human DNA, tardigrades, and millions of pages of digitized books about the human species.

IT WOULD BE THE FIRST MISSION OF PRIVATE LAND ON THE MOON.

DNA samples and tardigrades were sealed in a resin layer next to the digital file.

Although, so far, it is unknown whether the archive and the water bears survived the explosive impact.

DO TARDIGRADES TO THE MOON?

The tardigrads are micrometric creatures (the thousandth of a millimetre) with robust bodies and eight legs with small hands.

They are mostly known for their near indestructibility, as they would survive cataclysmic events, such as the explosion of a nuclear bomb or the fall of a meteorite.

They can withstand conditions that would be fatal to any other life form, resisting extreme temperatures of less than 200 to more than 149 degrees Celsius.

Another superpower is its ability to dehydrate their bodies in a state known as cryptobiosis. They retract their heads and legs, expel the water and wrinkle.

Scientists have discovered that late-grads can relive cryptobiosis 10 years or more after initiation. And when they wake up, they can reproduce again, without any problem.

For this reason, it is very likely that they have survived a forced landing in space, and are present at the arrival of the next manned lunar mission.
