Is suspended animation possible for space travel?

Even with better torpor-including technology, it may not be possible (or advisable) to keep crews in suspended animation for the entire trip. Instead, it’s more likely that astronauts will need to be woken on regular schedules to ensure they’re still healthy and address any issues that emerge on the spacecraft itself.

How will suspended animation help us?

Like CPR, suspended animation could delay the onset of cell death (necrosis) in seriously injured or ill patients, providing them with more time to receive definitive medical treatment.

Is long term stasis possible?

There’s evidence that even longer periods of stasis may be possible: a Japanese man once survived 24 days in a hypothermic state after a fall off a mountain ledge in Japan.

Is human stasis possible?

Typically, a patient stays in stasis for 2-4 days, though there have been instances where doctors chose to keep their patient in this state for as long as two weeks—without any complications. And the Uchikoshi case showed it’s possible to survive an even longer cooling procedure.

Is Cryosleep possible?

Interestingly, NASA, in partnership with SpaceWorks Enterprises, has been developing a cryogenic sleep chamber for astronauts. The “cryosleep” technology works by lowering the astronaut’s body temperature to 89-93°F (32-34°C), causing them to slip into a sort of hibernation.

How long can you be in suspended animation?

Normally, doctors would expect somebody with no blood reaching the brain to die or suffer irreversible brain damage within five minutes, but with EPR patients can potentially be kept alive for upwards of two hours.

How long can suspended animation?

Do we have Cryosleep?

There are now nearly 300 cryogenically frozen individuals in the US, another 50 in Russia, and a few thousand prospective candidates signed up. There are even more than 30 pets at Alcor’s chambers, the largest cryonics organization in the world in Arizona, that has been around since 1972.

Can you wake up from Cryosleep?

Are You Going To Wake Up From Cryosleep? More than 300 people let their bodies have cooled down to -200 Celsius and preserved in liquid nitrogen in the hope that someday in the future, science will be able to cheat death and make them wake up from their Sleeping Beauty state.

Would you age in Hypersleep?

One of the central conceits is that hypersleep massively retards the aging process. A year in hypersleep is equivalent to centuries in realtime. At the end of Alien, Ripley enters one of these pods and enters a state of cryogenic suspension. This is how she is able to survive 50+ years without (much) visible aging.
