Colony on Mars in 2020s is Unfeasible
The Mars One
project, is an ambitious plan to establish a permanent human settlement on the
planet beginning in 2025. It is the brainchild of Dutch entrepreneur Bas
Landorp. The $6 billion project calls for the use of existing technology and
will be funded through sponsors and private investors. Many have also
criticized the project's US$ 6 billion budget as being far too low to
successfully transport humans to Mars. A similar project study by NASA
estimated the cost of such a feat at US$100 billion.
There was a global search for the first humans
to set foot on Mars and make it their permanent home. More than 200,000 men and
women from around the world responded to the first call for astronauts. Last December, the organization, which is based in Amersfoort, the
Netherlands, picked 1,058 candidates to enter the second round of its selection
progress. One-third of those potential Mars settlers have been eliminated after
a review of their personal and health profiles, leaving 705 candidates,
including 54 Canadians, moving to the next round. After the interview round,
candidates will be narrowed down to several international teams consisting of
two women and two men each who will take part in an extensive training program.
The current plan is for a crew of four to depart and arriving on Mars in
2025. On its website, the Mars One
group says the first four settlers would be followed by more groups, every two
years. At first, the home base would be limited to provisions, oxygen and
water, but would eventually expand to everything the settlers might need,
including solar panels.
In an extensive
training period, the chosen ones will have to learn the skills they will need
on Mars and their journey there. The combined skill set of each astronaut team
member will cover a very wide range of disciplines. Obviously there would have
to be a doctor in the selection, along with a communications technician. There
would also have to have a geologist who would conduct tests with respect to finding
the water hidden below the surface. Also a qualified astronaut will be needed
to fly the one-way rocket to Mars. And naturally, there will also have to be a
biologist in that small community.
In my opinion, it is much too early to seriously
consider human settlement on Mars at this time in history. The proposed one-way
trip that is planned for the beginning of the next decade is pure folly for a
number of reasons.
Air
The air on Mars is extremely thin so without
earth-like air for them to breathe, the space travellers will be doomed and
their deaths by suffocation will be horrible. Of course they will bring oxygen
with them but that won’t last long and then what?
Any humans on
Mars would have to contend with the lack of oxygen that is only about 0.1%
compared to Earth’s 20%. Water vapor in the upper atmosphere of Mars could break into
hydrogen and oxygen by incoming ultraviolet and extreme ultraviolet rays from
our sun. Researchers investigated water photolysis, which happens when a water
molecule is torn apart by high-energy photons from the sun. Usually the water
(two hydrogen atoms and an oxygen atom) is broken into two parts, OH and H. The
H escapes to space because it is so light. Over time, more oxygen molecules would
build up until eventually O2 (molecular oxygen) form as well. Oxygen and Hydrogen combine to form
water. These are probably the most critical element required in large
quantities to sustain human life such as oxygen to breath and hydrogen to form
with the Oxygen to make drinking water.
Most of Mars's carbon dioxide is actually not in
the atmosphere, but instead it is locked up in the polar caps in the form of
dry ice. There is considerable
quantities of water-ice permafrost that may be present in the subsurface of the
polar regions just a few tens of centimeters down—permafrost that was finally
discovered in 2002 by JPL's Mars Odyssey
mission.
The habitants would have to bring equipment that
can extract oxygen and carbon dioxide from the air and the dry ice from the
surface respectively and then pump the oxygen into the pods. With the right equipment, it is possible to extract
breathable air into the pods but how long it would take to do that, I have no
idea.
However humans cannot simply live on
oxygen alone. Oxygen
only makes up about 21% of air. About 78% of the air you breathe is made
up of another gas called nitrogen. There are also tiny amounts of other
gases like argon, carbon dioxide and methane. The latter is a gas that emanates
from humans and animals.
Argon is the third most common gas in the Earth's atmosphere, at 0.93% (9,300 ppm),
making it approximately 23.8 times as abundant as the next most common
atmospheric gas, carbon dioxide (390 ppm). Nearly all of this argon is radiogenic
argon-40
derived from the decay of potassium-40
in the Earth's crust. I don`t know if it exists in the
crust of Mars. The Martian atmosphere contains 1.6% of 40 Argon
which is 5 ppm of Argon.
The carbon dioxide can be extracted from the dry ice and the atmosphere.
Water
Water on Mars exists today almost exclusively as ice, with a small
amount present in the atmosphere as vapour. Current knowledge
suggests there is plenty of
frozen ice at the Martian poles. This means that the habitat will
have to be very close to the frozen ice. It gets cold enough at the poles for
carbon dioxide to freeze out of the thin air. Abundant
water ice is also present beneath the permanent carbon
dioxide ice cap at the
Martian South Pole and in the shallow subsurface at more temperate
latitudes. More than five million cubic
kilometers of ice have been identified at or near the surface of modern Mars,
enough to cover the whole planet to a depth of 35 meters. Equipment can be brought to Mars to extract
the water from the dry ice and pump it into a large tank that is connected to
the pods.
Low
Atmospheric Pressure
The most
serious immediate effect on the humans on Mars would be from the low
atmospheric pressure that is nearly a vacuum compared to Earth. Chris
Webster from NASA's Jet Propulsion Laboratory, which manages the Curiosity rover roaming Mars, said in an
email, “Within minutes the skin
and organs would rupture, outgas, and produce a quick, painful death.” That is
why they would always have to wear space suits when they are outside of their
living quarters or any other structures that contain air.
The criticism
Mars One has
received a variety of criticism, mostly relating to those going on that Martian
venture, medical and technical feasibility.
People
What kinds of
people are prepared to leave Earth and spend the rest of their lives on a
planet that is bare and environmentally hostile? According to Norbert Kraft, the chief medical officer and
head of the astronaut selection program, the aspiring Martians should have five
qualities—resilience, adaptability, curiosity, empathy, and creativity. But
there has to be more than that. I think
they would have to be adventurers, risk takers, have the desire to be the first
humans to live on another planet and most importantly, to leave their mark in
history.
Here is a real contentious question. What
kind of person would leave his or her spouse and children forever simply in
order to leave his or her mark in history? Such persons could say that they are
sacrificing themselves in the name of progress but the truth is; they are sacrificing
their families in the name of fame.
I don’t believe that any of these people wishing to go on that trip who are already
married should be selected for that venture. Think about it for a moment. There
will be the same number of woman as men flying to and living on Mars at this
initial venture. Naturally they will pair up and have sex together and no
doubt, eventually have children. Those Martian pilgrims who are married on
Earth will in effect be committing adultery.
And surely, the love of their spouses on Earth will fade as they
gradually grow more attached to their spouses
on Mars. That in my opinion, is not
treating their spouses on Earth fairly and in essence, is a depraved way to
begin Man`s exploration into space.
Cabin
fever is an idiomatic term, first
recorded in 1918, for a claustrophobic reaction that takes place when a person or group is isolated
and/or shut in a small space, with nothing to do for an extended period. Cabin
fever describes the extreme irritability and restlessness a person may feel in
these situations.
The first team of Martian
pilgrims will comprise of only four persons—two men and two women. I don’t know
if the women will live in a different pod than the men or if the four will pair
up as couples living in the two pods.
Imagine if you will, you
and your spouse are sharing a cabin that comprises of only two small rooms in a
desert. The four of you cannot meet in
any of the rooms since the rooms are not large enough.
Now I know what you are
thinking. The four Martial pilgrims can meet in the lander that landed on the
planet. But if they do that, they will have to always wear their space suits
since the oxygen brought with them will have to be used for the pods, the
narrow enclosed walkway that connects the pods with one another and their space
suits. Quite frankly, I don’t believe
that they will be socializing in the lander even though there would be space
enough for them to do it as the various items such as food, water, building material
are gradually removed from the lander.
I suppose there would be some form of
socializing between the two couples as they work together and even when the
couples are in their own pods but each couple would only be able to communicate
by onsite radio if they are in their own pod. On couple could stand in the
hallway outside the other couple’s pod and further, the women could temporarily
share a pod as so could the men. By doing this, it would increase the communications
potential between the four of them.
One thing you would have to be
sure of and that is that the four of you get along well with each other and
more importantly, you and your Martian spouse get along with each other. If
there was friction between any of you,
Hell on Earth will seem like Heaven compared to Hell on Mars since on Mars,
there is nowhere else where you could go to get away from the person you hate.
When experiencing cabin
fever, a person may tend to sleep and have distrust of anyone they are with.
This means that in order for the couples to live harmoniously, they would have
to pair up for at least a year before they leave Earth to go to Mars. That would
be a real problem if they are already married to someone else. There was a
married couple who were considered for the trip but later it was determined
that one of them wasn’t eligible.
One therapy for cabin fever
may be as simple as getting out and interacting with nature. Research has
proven that even brief interactions with nature can promote improved cognitive functioning and overall well-being. However, it is one thing to wander about in a
beautiful forest with a lake close at hand and quite another thing to wander around
a desert in a space suit. If anything, it would increase the symptoms of cabin fever.
Cosmic radiation
The radiation environment
of deep space is very different from that on the Earth's surface or in low Earth
orbit, due to the much larger flux of high-energy galactic cosmic rays along with radiation
from solar proton events and the radiation
belts. Mars lacks a thick
atmosphere, ozone layer,
and magnetic field, allowing solar and cosmic
radiation to strike the surface unimpeded.
Galactic cosmic rays create
a continuous radiation dose throughout the Solar System
that increases during solar minimum and decreases during solar maximum (solar
activity). The inner and outer radiation belts are two regions of
trapped particles from the solar wind that are later accelerated by dynamic
interaction with the Earth's magnetic field. While always high, the radiation
dose in these belts can increase dramatically during geomagnetic storms and substorms.
Solar proton events are bursts of energetic protons
accelerated by the Sun. They occur relatively rarely and can produce extremely
high radiation levels. The damaging effects of
ionizing radiation on cellular structure is another one of the prime limiting factors
on the survival of life on the surface.
Astronauts on Apollo
and Skylab missions received on average 1.2 mSv/day and
1.4 mSv/day respectively. (measure of the health effect of low levels of
radiation on every human body each day) Since the durations of the Apollo and
Skylab missions were days and months, respectively, rather than years, the
doses involved were smaller than would be expected on future long-term missions
such as the one scheduled to go to Mars.
Because humans have not
been on Mars so far, the only known pathology associated with space radiation
exposure is a higher risk for radiation
cataract among the astronauts.
It has been known for many years that large doses of
ionizing radiation, (very much larger than background levels) can cause a
measurable increase in cancers and leukemia’s (cancer of the blood) after some
years delay. Therefore,
the best potential locations for discovering life on Mars may be in subsurface environments. But Mars One hasn’t planned for that.
Further, they don’t even have the tunneling equipment to build subsurface
environments. And if they did, who would be qualified to handle such equipment?
Summary
In January 2014, German
former astronaut Ulrich Walter
strongly criticized the project for ethical reasons. Speaking with Berlin's Tagesspiegel, he estimated the probability of reaching Mars alive at
only thirty percent, and that of surviving there more than three months at less
than twenty percent. He said about those backers and leaders of the Mars One project, “They don't care what
happens to those people in space.”
It is my sincerest belief that this
venture is doomed to failure. And what makes the Mars One project really obscene is that those who fly to Mars on
this futile mission will have no way of returning home if they realize that
they are going to have an early death if they remain on that barren planet. The
project leaders and backers know this.
It is conceivable that some
day, perhaps near the middle of this
century, a team of construction workers
will go to Mars and work in 30-day shifts before returning permanently to Earth
and build subterranean housing units so that pilgrims going to Mars can work
and live there and do so without suffering from any harm to their health. If
that happens, it will cost hundreds of billions of dollars to do this.
S
hould Mankind enter such a
venture? Well we all know that Mankind
on Earth will finally be wiped out when the sun expands but that won’t happen
for several million years from now.
Quite frankly, I think we as mature thinking human beings should work on
much more important endeavors in this era that we are currently in.
Our human race is ever expanding and
more living space where vegetation can grow is in my opinion more pressing than
attempting to colonize another planet. I think that the financial backers of Mars One should donate their money
towards turning some deserts into living areas. They did it in Nevada when they
turned desert land into Las Vegas.
Folly loves those who martyr
themselves for fame. If those chosen to
go to Mars do so and die shortly thereafter, the fame they will be remembered
in history will be that of their folly.
