Scientists believe there may be life on the Moon - that travelled there from Earth
There may well be life on the Moon, according to scientists - and it may have got there from Earth.
Scientists believe unmanned Israeli spacecraft the Beresheet was carrying a few thousand tiny tardigrades, supposedly the hardiest creatures on our planet, when it lost control and crashed on the Moon.
The US-based Arch Mission Foundation sponsored the tardigrades' off-planet exploration and thinks the millimetre-long animals may have survived.
Nova Spivack, the organisation's founder, told Wired magazine: "Our payload may be the only surviving thing from that mission”.
Also known as water bears or moss piglets, tardigrades look like eight-legged maggots with puckered mouths.
Tardigrades were discovered in the 18th century by the German zoologist and pastor Johann August Ephraim Goeze, and have since been found on mountain tops, in scorching deserts and in Antarctica's subglacial lakes.
Karl Shuker, in his book The Hidden Powers of Animals, claimed Tardigrades survived being frozen in liquid helium and being boiled at 149C.
The little creature's secret is its ability to shrivel into a seed-like pod, expelling nearly all of its water and drastically slowing its metabolism.
Lukasz Kaczmarek, a tardigrade expert and astrobiologist at the Adam Mickiewicz University in Poland, said the animals could have survived the crash landing.
"Tardigrades can survive pressures that are comparable to those created when asteroids strike Earth, so a small crash like this is nothing to them," he told The Guardian.
Mr Kaczmarek added that they could survive for years on the Moon.
Dehydrated tardigrades have been revived after years in an inactive state by being placed in water.
The animals then became active again and fed and reproduced as normal.
