Lunar Ark

Although we have the so-called “Doomsday Vault” that stores seed samples from every plant we'd need to feed ourselves in case of emergency, a plan funded by NASA hopes to build a cryogenic vault on the moon. It would store plant seeds and DNA samples of Earth life as a backup to the backup plan. University of Arizona aerospace engineering assistant professor Jekan Thanga is working on this plan that they're calling the lunar ark. (Originally aired: March 30th, 2021)
