Building a lunar ark is no small assignment, but based totally on a few “quick, lower back-of-the-envelope calculations,” Thanga stated it’s no longer as overwhelming as it could sound. Transporting approximately 50 samples from every 6.7 million species might require approximately 250 rocket launches. It took forty rocket launches to construct the International Space Station.

“It’s now not loopy big,” Thanga stated. “We had been a touch bit surprised about that.”

Cryogenics and Quantum Levitation

The mission idea builds on another undertaking Thanga and his group previously proposed, in which miniature flying and hopping robots known as SphereX enter a lava tube in teams. There, they could accumulate samples of regolith or dust and lose rock and gather data about the layout, temperature and makeup of the lava tubes. These records may want to tell the construction of the lunar base.

The team’s model for the underground ark consists of a set of solar panels at the moon’s surface that might provide power. Two or more elevator shafts might lead down into the facility, where Petri dishes would be housed in a series of cryogenic preservation modules. An extra items elevator shaft might be used to transport construction cloth so that the base can be extended within the lava-tubes.

To be cryopreserved, the seeds should be cooled to minus one hundred eighty C (minus 292 F) and the stem cells saved at minus 196 C (minus 320 F). As a reference for just how bloodless that is, the Pfizer COVID-19 vaccine ought to be stored at minus 70 C or minus ninety-four F. The fact that the lava tubes are so cold, and the samples have to be even less warm, and way there’s a chance the steel components of the base ought to freeze, jam or even cold-weld collectively. On Earth, commercial airlines forestall operating when floor temperatures attain minus forty-five to minus 50 C (minus forty-nine to minus fifty-eight F).

However, there’s a manner of taking benefit of the extreme temperatures by way of the use of an otherworldly phenomenon called quantum levitation (see video below). In this manner, a cryo-cooled superconductor material – or a material that transfers power without dropping any heat, as a conventional cable does – floats above a powerful magnet. The two pieces are locked collectively at a fixed distance, so anywhere the magnet is going, the superconductor follows.

“It’s like they’re locked in the region by means of strings, however invisible strings,” Thanga said. “When you get to cryogenic temperatures, odd matters manifest. Some of it simply seems like magic but is based totally on tried and laboratory-tested physics principles at the threshold of our understanding.”

The team’s ark design makes use of this phenomenon to make the cabinets of samples glide above metal surfaces and feature robots navigate via the ability above magnetic tracks.

There is a lot of extra research to be carried out on how to construct and function the ark, from investigating how the preserved seeds are probably affected by a loss of gravity to fleshing out a plan for base communications with Earth.
