Suspended Animation Could Be The Boost For The Mission-To-Mars

in #technology6 years ago

Introduction

After man's amazing feat in space travel which was indicated by the moon-landing of July 20th 1969 by the Apollo II crew (Neil Armstrong, Michael Collins, and Buzz Aldrin), there have been considerable plans over the years to surpass this feat. And in the bid to do this, propositions have been made for another manned stellar travel, and this time, it has been termed "Mission-To-Mars". In this survey, we will be looking at a specific technology that would be a boost for astronauts to survive such a long distant and brutal journey; and this is the Suspended Animation (Cryo-Hibernation).

Before discussing in details the concept of suspended animation in space travel, we will briefly look at the proposed NASA's Mission-To-Mars to understand the need for this kind of technology for the astronauts.

Mission-To-Mars

There have been some plans to put humans on the red planet. Before now, it was considered a progression in futility, but like you may know, this is no longer a question of "if it is possible", but "how will it be done".

In furtherance of this proposition, a contender for this space mission has arisen; the young teenager Alyssa Carson (Yes! She has indicated interest for the journey). And no doubt, this journey comes with risks, just like you'll see shortly. But according to Alyssa:

If the option was to go to Mars and die, I would still be part of the mission. - Alyssa Carson [culled from the video source]

Hey!! You ain't gonna die, kid. Just hang on; technology has got your back

Some may ask, when is the proposed date for the Martian trip? According to NASA, this has been pegged around 2033 for some obvious reasons; among others; is the fact that, in that year, the distance between Earth and Mars will be closer than it has ever been in the last 2millennia.

But even at this, taking this journey is not like any other journey here on Earth. Now, how long; on average; can this journey last? Actually, this is where the major challenge lies. An exposition made by Mars One has indicated that this journey can take an average of 6-8months (assuming that the journey is undergone in one of the fastest spacecraft ever; which is the NASA's Juno; having a top speed of 165,000mph).

Okay! Truth be told; how can humans endure such journey? Well, a technology has emerged to give a boost to this.  Now we will be looking at the concept of Suspended Animation (Cryo-Hibernation) as it relates to space trips.

Concept of Suspended Animation

Have you ever observed the "lungfish" and their ability to pass through the unfavorable condition in a rather sleep-like state (even outside water) for months? Okay, what if humans can be made to also pass through harsh conditions in an inactive state? That is the idea behind suspended animation.

Suspended Animation is a process in which a living creature (humans; in this contest) are put in a virtually inactive state for a period of time without degradation or mutilation of the person's body. This is just like sleeping through time; but in a rather different manner. There are ways to achieve suspended animation, but we will be focusing on the Cryo-Hibernation (I.e, the temperature-induced hibernation). I know someone could ask: "How would it be possible to cryogenically hibernate humans and revive them successfully?". Okay, let me use this real life case as reported by bbc.co.uk to buttress the possibility before I continue.

In the year 2016, a particular man; Mitsutaka Uchikoshi; who was on a mountain-climbing expedition in the cold mountains of Japan, fell off and went missing. He was later discovered after about 24days frozen. But amazingly enough, he didn't die, but was cocooned in ice, in a kind of suspended animation. His internal organs were momentarily suspended too, which left him in a condition described as "apparent death". When he was found, he was resuscitated and he has been leading a fairly normal life.

Though it has not been proven scientifically how he was able to survive this for these number of day, but it is worthy to note that; if someone can achieve this without any technological help; I believe with the help of emerging technology, we can replicate this; even better.

But in the case of the proposed Martian trip, you can't just put astronauts inside a freezer and send them to Mars. So how does this hope to be achieved?

A research was heralded by a team of researchers from the SpaceWorks Inc, led by Dr John Bradford as seen in their publication. This research proposes the use of "Therapeutic Hypotemia" as a means to achieving this suspended animation.

This is a kind of procedure that has been employed in some surgical interventions like heart and brain surgery, in which the person's temperature is reduced so as to slow down metabolism, decrease the heart rate, and consequently slowing down the blood pressure. Medically, people have been seen to be put in this state for days and were able to survive. But with cutting-edge technology, propositions have been made to further extend this.

How will this work? Dr John Bradford has proposed a Spaceworks Statis Chamber, which he hopes to use in achieving "Deep Space Sleep". But unlike what we may have been made to believe from our sci-fi, this chamber will only work intermittently like a kind of shift. In which the astronauts would be hibernated and resuscitated intermittently (maybe in weeks) and repeating the same process, instead of a straight hibernation. This process would be automated with a passage of a robotic transnasal tubes into the person's body. The function of these tubes would be to provide warming mechanisms to resuscitate the astronauts from the stasis and also to provide a cooling mechanism for the hibernation process.

This is an emerging technology, and hence, there are many challenges that need to be circumvented. For example; after resuscitating someone from cryostasis, he/she could temporarily be paralysed. I mean, staying in one place for weeks would do the same to you. But hey!! Solution has been found for this, and that is using a "Neuromuscular Electrical Stimulator" to artificially induce the contraction of the muscles. Boom!! That would take care of the temporal paralysis.

With advances in this and other emerging technologies, the Mission-To-Mars would not be an impossibility after all. History is about to be made yet again.

Conclusion

As plans are underway to send humans to Mars, some possible options to sustain the astronauts in the course of the journey have been raised, and one of them is to employ the technology of suspended animation. No doubt, with the advances in this; in the not-so-distant future; Martian trips would be comparable to any other journey on Earth. Maybe this could, one day, lead to the establishment of an extraterrestrial colony (Martian Colony). But until then, let's keep an open mind as we watch what the future holds.

Haha I won't go to mars oo My question is will the trip be one way? I mean will the individuals return ?

Lol. The sincere truth is; there is no guaranteed return. But hey! You would make history :)

I guess my dislike for anywhere below freezing point has put me out a Mars trip. Good post and Keep our flag flying high.

Lol. Maybe they'll figure out another way to send you to Mars without hibernating you :)

Thanks for coming around baba

I didn't the story from this guy called Mitsutaka Uchikoshi, it is amazing the fact that he could survive those harsh conditions for so long.

It is just a matter of time for space exploration to become more common than ever.

By the way, the technology you are discussing is like the technology in the movie Passengers, a very nice movie I recommend you to check out in case you haven't check it.

Cheers!

It is just a matter of time for space exploration to become more common than ever.

Truism. And ultimately, humankind could finally become interplanetary species.

By the way, the technology you are discussing is like the technology in the movie Passengers

I guess I should go get the movie.
Thanks a lot buddy

With the advancement on space technology, this kind of outer universe environment simulator is much needed. If its practically possible to train humans in these simulators, this would a great milestone for the goal of colonizing the red planet!
Another great article bro. Cheers!

You're right. Very soon, humankind could become interplanetary.
Thanks for coming around

wow, what a wonderful write up. if and if i have chance, i would have to travel to mars. nice post.
looking forward to more of your post.

if and if i have chance, i would have to travel to mars

Lol. Hope you're willing to subject yourself to the strains involved in the Martian trip? It's not as easy as it sounds, and it could be a one-way ticket :p

Thanks for dropping by

Travel time to mars probably takes less than a year. So it not really necessary to put all the colonist in suspended animation.

Thanks for dropping by. Actually, it's between 6-8months, but there are many things to consider; food supply for the crew members (what if they run out of food supply?), and other harsh conditions, etc. But putting them intermittently in cryostasis would lower their metabolism rate, and hence they would pass through some period in a sleep-like state.
This is an emerging technology, however, and is subject to reservations

Yeah I guess if there are a lot of crew on board it makes sense to freeze them. But if there are only a few it seems more efficient to have a space vegetable garden. The advance with space gardening seem to greater than in suspended animation -> https://en.wikipedia.org/wiki/Plants_in_space

Space vegetable garden, wow.. That makes a lot of sense. Thanks for providing this link. I guess I'll bookmark it and read it up later

https://steemitimages.com/DQmPArbT348pPh2Apc6haChk8KfZZJod33KLYGaPrAxGbUw/download%20(2).jpg)its a really nice post... gravity of mars is less than the earth.. but the ship have to cross both of it... it is possible but not so easy... NASA try its best...
i can give some information... at first some flies travel the space.... the dog named laika who died for the mission...

but gravity of mars is more than the earth

Hi @kumilla, you're misplacing some details. The surface gravity of Mars is far less than that of the earth. The Martian surface has a gravity of 3.711m/s^2, while that of the earth is 9.807m/s^2

P.S: Laika didn't go to Mars, it stopped at space. It was the first animal in space

sir. again read the comment pls... I add laikas topics in space traveling.. not for mars.... thanks for replying... i will happy if u visit my blog.... i am new here... i love science... more contant i wrote according to nasa... if u incourse me i will write more....

i am sorry... i told that about gravity.... there is a long distance between earth and the mars.... but moon is closer to earth..... the ship have to cross earths gravity and mars gravity....

Lol. Thanks for coming around

Please what am I looking for in the space

Nice work @samminator
Followed you

Please what am I looking for in the space

Lol, maybe aliens :)
