Tardigrade Moon


On April 11, 2019 unmanned Israeli spacecraft Beresheet crashed into the Moon during a failed landing. Historians will mark this day as first unintentional Moon crash in 48 years, learn more at https://www.livescience.com/65218-moon-crash-beresheet.html

That said, Beresheet might be credited with depositing life on the Moon. Robotic lander Beresheet carried a payload of 30 million digitized pages of information about human culture and society, human DNA samples and Tardigrades. Human DNA and Tardigrade were locked in resin, held in place by sticky tape onto which thousands more Tardigrade were placed.

Tardigrade, aka “water bear”, are the only known life form capable of surviving airless vacuums of space and lethal radiation levels. Remarkable yes, mind blowing when considered with additional facts – Tardigrade can survive six times the pressure of our deepest ocean, frozen to absolute zero (-273 C) or boiled above 150 C. Dehydrate a Tardigrade for years then add water, voila – business as usual. Eventually they succumb to old age, but don’t hold your breath, life expectancy is 200 years.

In the wake of Beresheet’s fiery demise, indestructible Tardigrade litter the lunar surface. Did they vaporize on impact? I care to think not – Tardigrade are the definition of extremophile, if anything can survive crash landing on the Moon, it’s a Tardigrade.

Tardigrade


Did life on Earth emerge spontaneously from primordial pools, or fall from the cosmos with meteoric fanfare? Not sure? Ponder the Tardigrade.

Tardigrade or “water bear” are the only known life form capable of surviving the airless vacuum of space and lethal radiation levels. Remarkable yes, mind blowing when considered with additional facts – they can survive six times the pressure of our deepest ocean, frozen to absolute zero (-273 C) or boiled above 150 C. Dehydrate a Tardigrade for years then add water, voila – business as usual. Eventually they do succumb to old age, but don’t hold your breath, life expectancy is 200 years.

Discovered by Italian Lazarro Sapallanzani in 1773, water bears are thought to have inhabited Earth for 530 million years. Measuring 0.5 mm – 1.2 mm in length, they can be found anywhere on Earth.

The Tardigrade begs evolution to explain why. Evolution adapts species for life on our planet, why would a species need to withstand ravages of time and space?
