well we were made to live on earth. human beings trying to exist in outer space can only lead to problems. simple as that, but NASA and silly people will keep wasting money trying.
Trying space travel and other explorations like inner space maybe outside of our capabilities but it also points out vulnerabilities we may be able to conquer. NASA has a huge budget (we pay for it) They may be able to use information to cure viruses instead of driving them to dormancy to come back later. I doubt it but killing viruses is a good goal. Inhabiting Mars I’m not sold on, but heck I’m an old fart.
