Explained NASA How Deep Sleep will work to take crew to Mars

Explained NASA How Deep Sleep will work to take crew to Mars

SpaceWorks Enterprise is the company that is being funded by NASA to further explore the effects of human stasis that reduces the amount of pressurized volume required for a hibernating crew by five-fold.

SpaceWorks’ study, which was funded by NASA, shows a five-fold reduction in the amount of pressurized volume need for a hibernating crew and a three-fold reduction in the total amount of mass required, including consumables like food and water.

Putting astronauts into a deep sleep would make reaching the red planet easier and cheaper

Is human HIBERNATION idea is the cheapest way to reach Mars?

A NASA-backed study explores an innovative way to decrease the cost of a human expedition to Mars put the crew in stasis.

The deep sleep, called torpor, would reduce astronauts’ metabolic functions with existing medical procedures.
Torpor also can occur naturally in cases of hypothermia.
This is a form of deep sleep, also referred to as a type of 'hibernation' 

Therapeutic torpor has been around, in theory, since the 1980s and since 2003 it has been a staple for critical care trauma patients in hospitals.

Torpor reduces the metabolic needs for a human, essentially placing them in 'hibernation'.

How deep sleep will work in Mission to Mars?

The proposed stasis program for astronauts will involve a system divided in two parts.

The first stage will require astronauts inhale a coolant similar to that used in medical applications of torpor.

The next stage will involve assigning a crew member to stay awake for a period of two to three days and then hibernating for two weeks.

The crew would be put to sleep for the 180-day journey to Mars by lowering their body temperature through their nose
They would then be woken by stopping the flow of coolant at the red planet.
Once mission was complete, they'd be put to sleep again for the return trip.

The proposal would see a crew ‘hibernate’ for up to 180 days, allowing them to make the journey of 350 million miles (560 million km) with a reduced need for food and water.

The crew would be kept alive through intravenous feeding, before being woken at their destination by inhalation of a coolant gas.

To put astronauts in stasis, a system called RhinoChill would be used, which reduces body temperature by about one degree per hour by supplying coolant through the nose.

At a temperature of between 32°C (89°F and 93°F), which takes six hours to reach, the crew would enter stasis.

Stopping the flow of coolant would then wake the crew when they arrive at their destination.

This means that on the journey to Mars, they could be placed in a fairly small capsule.

From Movies to Real Science  one more scientific idea towards reality

In past similar concept has been shown the movies or you will find them in books.

Example is 
Movie - 2001: A Space Odyssey which is based on the book
Release Date - Year 1968
2001: A Space Odyssey — film and novel — produced concurrently and released in 1968
The screenplay was written by Kubrick and Arthur C. Clarke, and was partially inspired by Clarke's short story "The Sentinel".
Clarke concurrently wrote the novel 2001: A Space Odyssey which was published soon after the film was released.

In 1991, it was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress and selected for preservation in the National Film Registry.

The film is structured into four distinct acts.
Daniel Richter plays the character "Moonwatcher" in the first act, and William Sylvester plays Dr. Heywood R. Floyd in the second.
Keir Dullea (as Dr. David Bowman) and Gary Lockwood
(as Dr. Frank Poole) star in the third act as the two astronauts on their voyage to Jupiter on board the spacecraft Discovery One, with Douglas Rain as the voice of the sentient computer HAL 9000 who has full control over their spacecraft.
The fourth and final act of the film follows the journey of astronaut David Bowman "beyond the infinite".

The U.S. spacecraft Discovery One is bound for Jupiter. On board are mission pilots and scientists Dr. David Bowman (Keir Dullea) and Dr. Frank Poole (Gary Lockwood), and three other scientists who are in cryogenic hibernation. Most of Discovery's operations are controlled by the ship's computer, HAL 9000 (voiced by Douglas Rain), referred to by the crew as "Hal".

The Space Odyssey series is a series of science fiction novels by the writer Arthur C. Clarke. Two of the novels have been made into feature films, released in 1968 and 1984 respectively. Two of Clarke's early short stories may also be considered part of the series.

Short stories:
"The Sentinel" — short story written in 1948 and first published in 1951 as "Sentinel of Eternity"
Encounter in the Dawn" — short story first published in 1953 (re-titled "Encounter at Dawn" or "Expedition to Earth" in some later collections)

Novels/Films:
2001: A Space Odyssey — film and novel — produced concurrently and released in 1968

2010: Odyssey Two — 1982 novel, adapted as the 1984 film 2010 with screenplay by Peter Hyams
2061: Odyssey Three — 1987 novel
3001: The Final Odyssey — 1997 novel
