Why We Need A ‘Moon Ark’ To Store Frozen Seeds, Sperm And Eggs From 6.7 Million Earth Species:

Species or planets[sic] could be wiped off the face of the Earth any minute—so we need a “Moon Ark” to safely store frozen eggs, sperm, seeds and other DNA matter from all 6.7 million Earth species.

That’s according to students and staff at the University of Arizona, who at the IEEE Aerospace Conference last weekend divulged details of an ambitious “modern global insurance policy” for our planet.

Their daring plan is to build a complex in the Moon’s lava tubes staffed by robots and fuelled by solar panels on the lunar surface.

[...] The incredible plan to build a lunar base that includes an underground ark goes something like this:

• Ball-like SphereX robots—each weighing about 11lbs/5kg and able to fly and hop—to enter, explore and map the Moon’s recently discovered (in 2013) network of underground lava tubes, each about 328ft./100 meters in diameter.
• Design, and then construct, underground ark in the lava tubes, with solar panels on the lunar surface and elevator shafts that access the facility.
• Launch 250 rockets to the Moon, each taking 50 samples from each of 6.7 million species (it took about 40 to build the International Space Station).
• Store the petri dishes of seeds in cryogenic preservation modules inside the lava tubes, which would shield the seeds from solar radiation, meteorites and temperature fluctuations.
• The seeds would be kept at around -292ºF/180ºC, temperatures that would likely cold-weld together metal parts of the base. Cue “floating shelves” made from cryo-cooled superconductor materials that enable quantum levitation above a powerful magnet.
• Staff the facility with robots that navigate through it above magnetic tracks. Robots that can operate under cryo-conditions don’t yet exist—though the proposers admit that new technologies will be needed to make the “Moon Ark” a reality.
