WASHINGTON, August 7 – There could be life on the moon: thousands of nearly indestructible creatures that withstand extreme radiation, boiling heat, the coldest temperatures in the universe, and decades without food.  These terrifying-sounding creatures are not aliens, but microscopically small earthlings known as Tardigrades, who probably made it through the Israeli Beresheet probe in April after a crash landing on the lunar surface, said the travel agency responsible for their trip. Organization with yesterday.
Based on an analysis of the trajectory of the spacecraft and the composition of the device in which the microtians were stored, "we believe that the survival chances for the tardigrades … are extremely high," said Nova Spivack, co-founder and chairman of the Arch Mission Foundation, said AFP.
The nonprofit association is dedicated to disseminating backups of human knowledge and biology of the earth throughout the solar system, a search that it likes This has led to the creation of an "Encyclopedia Galactica", first published by science-fiction author Isaac Asimov was mentioned.
"Tardigrades are ideal because they are microscopic, multicellular and one of the most enduring life forms on planet Earth," said Spivack.
He added that the tiny creatures, which are less than one millimeter (0.04 inches) in size, had been dehydrated to give them a floating animation, and then "enclosed in an artificial amber epoxy resin The future should be revivable.
The Tardigrads were kept in a "Lunar Library", a nanotechnology device resembling a DVD containing a 30 million page human history archive that can be viewed under the microscope, as well as human DNA.
Spivack is confident that these effects have also survived – but they are not the first genetic code or the first forms of life deposited on the barren celestial body.
This distinction belongs to the DNA and microbes contained in nearly 100 excrement bags and urine left by American astronauts during the Apollo moon landings of 1969-1972.
No rescue mission
Also known as water bears or moose pigs, tardigrades can live in water or on land. and are able to withstand temperatures of up to 150 degrees Celsius and down to minus 272 degrees Celsius, albeit for a few minutes.
The maggot-shaped eight-legged animals can return from dehydration to an inanimate shell for decades to withstand zero pressure in space and the shred depths of the mariana trench.
If they do not burn in an explosion, they can theoretically survive the tiny pressure on the moon's surface and the extremes of William Miller, a Tardigrade expert at Baker University, told AFP, "But to get active, to grow 'To eat and multiply, they need water, air and food.' multiply and form a colony, he added.
Nasa Astrob iologin Cassie Conley said that her exact survival time would depend on the state of the impact and the temperatures to which they are exposed.
"If they do not get too hot, they can survive for quite a long time (many years)," she told AFP.
"I would be more worried that the animals are being attacked by poisonous chemicals made of epoxy or glue", with which they were stored, in contrast to the conditions in outer space, she added.
Even though the creatures lived for several years, no manned mission to the moon is planned until the Nasas Artemis program at the South Pole in 2024 – far from Beresheet's Serenity Crash Site, you make it home.
"It is unlikely that they will be rescued in time, so my assumption is that even if they have survived, they are doomed to fail," Rafael Alves Batista, a physicist at the University of Sao Paulo, said in a 2017 report on the extreme resilience of Tardigrades, AFP said. – AFP
