Deep Freeze - long a main stain of scifi movies, NASA is getting serious about suspended animation for long duration spaceflight. If successful, the work has profound implications not just for space exploration, but the possibility of prolonging your life span here on Earth (although, it’s more like time skipping than true longevity). It is however, not for the squeamish, requiring some serious plumbing between man and machine.
Flying people to another planet poses a ton of technical and logistical challenges. One of the largest hurdles is figuring out how to fit a crew on a spaceship with enough food, entertainment, and amenities to last for the estimated 180-day journey to Mars.
NASA is bankrolling research into the technology necessary to put people to sleep for months at a time via SpaceWorks. According to the company, inducing torpor in a crew of astronauts would eliminate the need for space-wasting accommodations like food galleys, exercise equipment, and large living quarters. Robots that electrically stimulate key muscle groups and intravenously-delivered sustenance will take care of all that.
Check out the original post for all the gory details (literally) of how the system might work. Considering all the prodding and probing astronaut candidates have to go through as part of the selection process, I guess this additional bit of discomfort is just a splash in the ocean anyway.
