The use of tardigrades in space, first proposed in 1964 because of their extreme tolerance to radiation, began in 2007 with the FOTON-M3 mission in low Earth orbit, where they were exposed to space's vacuum for 10 days, and reanimated, just by rehydration, back on Earth.
Tardigrades have survived exposure to space. In 2007, dehydrated tardigrades were taken on the FOTON-M3 mission and exposed to vacuum, or to both vacuum and solar ultraviolet, for 10 days. [20] Back on Earth, more than 68% of the subjects protected from ultraviolet were reanimated by rehydration, and many produced viable embryos. [20]
The tested tardigrades were able to survive impacts of up to 3,000 km/h and momentary shock pressures of up to 1.14 GPa. The results suggest the tardigrades were unlikely to survive the crash because the shock pressure of the lander's metal frame hitting the surface would have been well above 1.14 GPa. [16] [14]
Tardigrades are one such creature, as you discover in the above video. They can endure boiling water, freezing cold, and even the vacuum of space by employing some very special survival strategies.
An Israeli spacecraft carrying tardigrades crashed into the moon. Whether they will survive is irrelevant. Tardigrades: we're now polluting the moon with near indestructible little creatures
The space vacuum did not much affect egg-laying in either R. coronifer or M. tardigradum, whereas UV radiation reduced egg-laying in M. tardigradum. [17] In 2011, tardigrades went on the International Space Station STS-134, [18] showing that they could survive microgravity and cosmic radiation, [19] [20] and should be suitable model organisms ...
Panarthropoda is a proposed animal clade containing the extant phyla Arthropoda, Tardigrada (water bears) and Onychophora (velvet worms). [3] Panarthropods also include extinct marine legged worms known as lobopodians ("Lobopodia"), a paraphyletic group where the last common ancestor and basal members of each extant panarthropod phylum are thought to have risen.
Dsup (contraction of damage suppressor) is a DNA-associating protein, unique to the tardigrade, [1] that suppresses the occurrence of DNA breaks by radiation. [2] [3] When human HEK293 cells were engineered with Dsup proteins, they showed approximately 40% more tolerance against X-ray radiation.
