I read this article in the daily newspaper a few days ago and found it very interesting. It is titled “After 9 months in space, mouse sperm yield healthy mice “. It concludes that “Besides looking ahead to long-term space crews and societies, the researchers see other reasons for saving sperm in space, including in the event of disasters on Earth. The moon would be ideal for underground sperm storage, they noted, in particular lunar lava tubes because of their very low temperatures, protection from space radiation by thick bedrock layers, and complete isolation from any disasters on Earth.”
So, what do you think? To me it seems like they are just outright telling us that human sperm can be sent into space without being damaged critically. So, therefore it is plausible that humans could be “planted” on other planets! Would you send your sperm or eggs into space??
