The Mars One Mission
Embrace
The Spirit, Alter The Plan
The Mars
One Mission overall should be seen as a positive endeavour. In a
world where human exploration of deeper space is not possible in the
near future due to shear cost, any genuine and inspirational plan to
do so should be welcomed no matter how unrealistic. While its Mars
attempt in about a decade will fail probably sooner than later for
one of multiple reasons, it will benefit Mars exploration in various
ways.
- It will inspire some people to focus more personal attention towards a future landing and to obtain the skills and training they will need to play a future role in progressing the endeavour. It may also inspire industry members with no aerospace connection to develop relevant sub-technologies and bid for aerospace sub-contracts thus gaining experience and a foothold in the aerospace door. The pool of aerospace resources available to develop a future Mars mission would thus be increased.
- The crew training planned by the Mars One foundation will include comprehensive simulations related to an isolated crew travelling to Mars and setting up a base and the lessons and experience gained from this should benefit an actual future mission. Also if they go about it correctly they should develop some realistic and better thought out numbers relating to the sizing and logistics of the space craft and consumable resources needed to get the crew to Earth orbit, to Mars and then down to the surface. On a negative note obtaining the result of these calculations is one of the more likely stages that the Mars One mission will flop.
- If the group maintains a highly publicised existence for a significant number of years then it can be expected to foster industry ties with a great many similarly interested organisations and aerospace members and to a certain extent form a connectivity hub that more strongly links those other organisations to each other. This networking will naturally benefit a future Mars endeavour. Many of these networked personnel including some from Mars One are likely to play actual roles in a future mission.
- (Its high profile flop rationally ought to encourage future plans to be more realistic)
With
qualified private aerospace companies scrambling in the coming years
to push tourists up above 100 km altitude and collaborate with a
national space agency to launch humans just into orbit, then the fact
that Mars One a non-aerospace organisation propose to bypass the moon
and land on Mars clearly shows that their communication lines with
reality are currently down. Indeed they publicly proclaimed ten
years to do so. While their relative small print acknowledged the
possibility of delays, one year on they had already failed as per
their publicity claims with the first of many predictable delays
adding two years.
How far
the attempted endeavour goes remains to be seen. In global
economically difficult times who will actually finance the endeavour
and with what rational expectation of results. The organisation
indicates that the technology required to make it possible already
exists. This is mostly true but is utterly misleading. Many
discreet chunks of existing sub-technology do not make a Mars
mission. They have to be further developed, integrated, tested,
upgraded and retested repeatedly to meet rigorous human space flight
standards. In practical terms they collectively would take a lot
longer than a decade to reach technological maturity. In the
particular case of the rover for example, the technology does not
remotely exist in a flight worthy developed manner and the
preparatory surface operation of everything else is utterly dependent
on it.
Mars
One talks about how eight landers will already have touched down by
the time a crew attempt to do so and there is certainly a relevant
argument here in terms of safety. What they grossly under emphasise
is that seven of those landers are vital prerequisites to a human
landing with five of their cargoes having to successfully carry out
complex operations after landing in preparation. The latter six are
to transit to Mars in chronological proximity meaning that they can
benefit relatively little from previous experience. Sending six
landing craft in unison is itself unprecedented and distinctly risky.
There is a prominent statistical risk that at least some of these
prerequisite cargoes will not launch on schedule or fail to land
successfully or fail to function properly. That immediately leads to
mission schedule delays occurring in approximately 26 month time
segments. Most notably the second lander is to include a rover with
final positioning of the next six cargo landers entirely dependent on
its functionality. It is doubtful that any near-future rover will be
physically capable of performing the tasks assigned to it. Yet it is
supposedly going to be designed, built and then launched
in 2020.
Being optimistic, a schedule slip of several years can be added just
for it alone although frankly two decades might be more realistic.
Also what if some cargo landers successfully land and are properly
placed but some do not, meaning that the latter have to be replaced
26 months later with the replacements possibly needing replacements
and additional time slips. The ones that are successfully landed and
placed will be sitting maintenance free for at least an additional
two year plus interval leaving them additionally prone to failure.
Mars One hardly mention the fact that launch delays and landing
failures would cleanly knock the schedule backwards. Objectively
looking at the seven prerequisite landings and the general lack of
Mars landing experience among the likely aerospace contractors, then
at least two such 26 month knock backs would seem likely due to post
launch failings. That's just to get the landers sitting intact on
the Martian surface but not trailered to the outpost location and
started up.
Mars One place
clear emphasis on how they will not launch the crew until green light
status is received for all systems on Mars. They place little
emphasis on the risks thereafter. Coming from nowhere, even putting
humans into orbit inside a decade is a challenge. They may be
contracting out to established aerospace companies but any human
spaceflight involvement those companies have or will have with say
NASA is overseen by that experienced administration. They are
without experience to set off on a committed several month journey
with limited redundancy. There is no prior human precedence for this
when considering the hazardous environment, system dependency and
non-availability of close support or any external resources besides
solar power. If there is a problem with a primary system or resource
early in flight, then redundancy will come into play. For a safety
margin in this unprecedented isolated duration, the redundancy itself
would need redundancy or else advanced and complex in-flight repair
skills that are unlikely to exist. During this several month transit
there is also a conceivable risk that one or more systems at the
unsupported Mars outpost suffer a serious failure. Worse still, what
if the outposts generated water or oxygen supplies leak? That would
be catastrophic. Assume the outpost systems remain operational. On
arrival at Mars the crew lander must undergo a hazardous direct
entry. Although to have been verified by eight previous unmanned
landings, the risk is what it is. Direct entry is arguably best left
to unmanned landers or crewed vehicles returning from the moon and
targeting a general region of the Earth surface with full recovery
services at the ready and also a breathable atmosphere. The Mars
crew vehicle from solar orbit approach speed, must accurately enter
and soft-impact land within survivable range of the outpost and rover
and with its environmental control continuing to function. It is
noted that a more realistic mission concept includes some of the same
risk elements but that does not negate them.
They basically
intend to finance this permanent endeavour through public interest of
one form or another. They do not account for the fickle factor of
the human attention span. Even if they somehow succeeded in
financing and landing four persons at a functioning outpost, they
then assume the responsibility and cost of keeping them alive. They
indicate that as more and more crew members arrive every two years
they will eventually be able to self produce complex components but
this leaves a gap of at least a couple of decades at the optimistic
end of the scale. During this significant number of years and for
the increasing crew complement, they must for example provide
replacement technology either as foreseen or for components that in
practical terms were not as maintainable and repairable as inferred.
This is in addition to the the cost of supplying additional life
support, living and supply units for additional crew. The supply
missions as always will face the risk of a post launch pad failure.
Mars One like to compare the business plan to the sponsorship and
broadcasting rights arising from the public interest in the Olympics.
A monolithically more obvious comparison that they curiously missed
for analysing long term viability is the Apollo program. In contrast
to the eyes of the world being transfixed by the Apollo 11 endeavour,
the later Apollo landings were cancelled primarily because dwindling
public interest meant that the tax dollars could not be justified.
People had even tuned out to a significant extent by the time of the
Apollo 13 problem such that some early 13 broadcasts were not aired
live. Mars One who of course reference only the first moon landing,
have basically indicated that public interest in the ongoing
pioneering adventures of the Mars settlers will keep the projects
finances rolling. Apollo proclaims otherwise. It would soon become
the day to day tedium of survival and repetitive panoramas with
limited adventures further afield being of more interest to trained
geologists. Of course a psychological crisis might perk viewer
numbers. Also with national or regional superpowers needing to show
off their prowess, it is inevitable that one or other of them would
high tail it to Mars within an additional decade or two and they will
broadcast their accomplishment for free. With such superpower plans
afoot anyway then the more years of many predictable delays before
Mars One could first make footprints, the less years they could
monopolise broadcasting rights. Indeed if they somehow did finally
succeed in landing persons on Mars, they might have the additional
risk of squishing an earthling.
Mars
One are acting like the endeavour is child's play, as if the worlds
reputable space organisations already have people on Mars and the aim
is just to be the first private organisation to send private
citizens. The worlds experienced space faring nations by a massive
margin, currently do not have the development and experience to
safely put people on Mars in a decade even if they were given a
magical money tree. It would be amazing if they could even do a Mars
flyby in that time frame. Nobody has that prerequisite experience
level in practical terms although a great many people imagine it to
exist. Mars One are completely out of sync with this reality and pay
it scant regard. Above some small unpainted reality signposts they
flash a large neon illuminated air of “can do”. A
“can do” attitude sounds great in principle but requires a
baseline level of realism. On less complex successful endeavours,
that baseline realism may tend to go unnoticed and therefore not be
identified as a prerequisite. It
is however always there quietly playing its role.
They
make a point of quoting a USA Mars landing mission success rate of
87.5% with an implication of it being a relevant comparison for their
project. Mars One are not NASA. Ignoring failure to leave Earth
orbit, the lander international success to failure ratio is actually
7 to 8 or 46.7% success. (Successes:
Viking 1, Viking 2, [ 1990 ], Mars Pathfinder, Mars Exploration Rover
Spirit, Mars Exploration Rover Opportunity, Phoenix Mars Lander,
Curiosity. Failures:
Mars 3, Mars 6, Mars 7, Phobos 1, Phobos 2, [ 1990 ], Mars Polar
Lander, Beagle 2, Phobos/Grunt.) ESA and Russia/Soviet Union have
vastly more aerospace experience at their disposal than Mars One and
their Mars lander success rate is 0%. Note the post-1990 lander
success rate increases to 62.5% internationally. Particularly note
how unreliable it is just to get an unmanned lander safely on the
ground although attempts have clearly improved. Even their
misleading 87.5% figure infers an unacceptable 12.5% chance of
fatality and they state it as if it's a confidence building fact.
As for
the crew candidates themselves the intention is apparently to filter
the many entrants down to about 24 (to 40) people comprising 6 (to
10) teams of four. It is to be expected that these people are all
individually intelligent, apt and psychologically healthy. Therein
lays the potential dilemma. If they are sufficiently intelligent and
apt then they have to realise the Mars landing is not possible
without vast resources of expert knowledge and skills and is
certainly not possible in about a decade. If they don't realise this
then unfortunately they really do not have the intelligence and
aptitude to be a competent crew member on such a demanding permanent
mission. It is in a sense something of a catch twenty two.
It may
come about that many of those with higher technical and survival
aptitudes assuming they even applied and stuck around, do demonstrate
a lack of belief in mission success due to their better understanding
of the challenges. This might occur through clever psychological
interviewing rather than them stating it directly. Since it is
natural to not invest time, money and effort in someone with a
likelihood of opting out of the mission close to launch day, then it
may come about that the final selected candidates do not have a
particularly high average aptitude. Even having higher aptitude
persons in a position where they might spread doubt over time would
be problematic. They themselves are likely to bow out of the
selection process anyway after having concertedly given Mars Ones due
opportunity to produce a developed and responsible mission plan
backed up by intermediate progress. Such a suboptimal aptitude level
in the candidate pool would tend to raise an additional red flag over
the project. Given the higher self sufficiency demanded of them
compared with a typical space mission, then aptitude is absolutely
vital. Absurdly in this case a belief in the viability of the
proposed mission design ought to be a disqualifier. A comparison
could be made with say NASA astronaut selection where in addition to
good personality and mentality, the selected crew will have suitably
high intelligence and aptitude for their specific roles but also a
rational belief in the ability of that experienced administration.
The
rational assumption is that the mission crew would die prematurely
even if they made it as far as the Martian surface but if the
individual members were shown to be sane and rational then why should
they not be allowed to set off on a probable suicide mission. They
exist, therefore they are dying anyway and it can readily be said
that exploring part of the greater universe is an ideal that
surpasses any judged value of their personal existence here on Earth.
Simply make sure that they sincerely acknowledge the risk of their
near future death.
In all
likelihood it will come to pass that the final selected crew members
while entirely willing and able to go to Mars will not truly expect
it to happen. Don't expect to hear them say so. Probably their
motivation will instead be to spend a part of their life actively
living out the spirit of exploration beyond Earth, be it without ever
leaving. That spirit of exploration is one thing about the Mars One
plan that is entirely true and realistic. They will relish the
prospect of moving in the same circles as like minded people and
spending a number of years at a headquarters and training locations
while additionally having responsibilities to help promote and
develop the missions they are intended to be a crew member on. If
the endeavour continues for enough years, some members will naturally
step aside. They may encounter age or health barriers. They may
become disillusioned with the potential of the organisation to
advance space exploration. They may simply choose an Earth bound
commitment that will forfeit their crew status. Some, previously
steadfast about their willingness to forego earthly freedoms will
come to the true realisation about what it would mean to
hypothetically never again enter an ocean under a blue sky even after
the subsided trill of stretching their legs for a Martian year in
highly limited living conditions.
The
availability of potential launch capability is not in doubt. A
different question is whether the relevant reputable aerospace
companies would
without reservation
actually involve themselves with providing the capability given
the likelihood of crew fatality prior to Mars footprints if they
actually set off. What country would enthusiastically allow them to
launch from within their international boundary or otherwise aid them
in their endeavour. Just because the crew are judged rational does
not automatically mean that they should be helped. The potential
suppliers might discreetly bow out when Mars One starts looking for
signed launch contracts.
However given the significance of the endeavour it seems likely that
they would indeed receive the logistics but under stipulated
conditions that would effectively force many years of delays to
attempt to meet developmental
and safety standards. This could extend
to the point where the whole plan becomes redundant because existing
capable space organisations are initiating Mars mission countdowns.
Additional delays might even be added along the way by some well
spoken opposition groups kicking up a controversy about deluded crew
members being taken advantage of and being sent to their deaths.
But
scrutinising that far ahead is jumping orbit without a spacecraft.
Realistically the project will probably flop long before. Donations
generated by publicity will not successfully summit the Mount Olympus
of escalating costs and potential serious backers are liable to be
invaded by sense. Realistic design calculations are likely to
mathematically prove that those involved are dreamers who dream a few
too many hours each day.
At that
point the Mars One foundation might disband completely.
Alternatively if it has made a proper impact on future exploration to
the extent it is capable of, then it might reduce in size to
back-burner status with core advocates promoting future endeavours
and maintaining industry connections. It would be doing good and
worthwhile things if it continues to inspire. Then at some bright
point in two or three decades it might re-spawn its Mars intentions
and play a part in a proper international Mars project spearheaded by
the worlds existing and experienced space faring agencies.
Then
again right now why not an entirely different initial goal embracing
the spirit
and a new name. “Moon Base One”, a permanent and expanding base
on the moon with full time highly trained residents. It is an
entirely worthy objective in the outward exploration of space and a
realistic one. No one resides there now. No one has been there in
more than forty years. The moon has not been conquered. Beyond the
talk, actually going there is a challenge. Residing there
permanently is a far greater one. No one else can actually do it
right now which in itself definitively proves how unrealistic Mars
One is. Humans must competently reside for long term periods on the
moon as a responsible training step for outward exploration to Mars
and beyond. (See main article: Between The Moon And Mars)
One of the reasons
why many people generally are not excited about establishing a
permanent presence on the moon is that certain Mars advocates as per
their own agenda proactively downplay the usefulness of returning
there. People need to be enlightened about the relevance of a moon
base not just as a training and exploration ground but as an amazing
feat in its own right. It is literally out of this world with no
other current comparison. Anyone born after 1972 does not know what
it means to stand on Earth with the knowledge that there are humans
simultaneously standing on another celestial body. Mars One would
need with humility to close down their Mars plan as an active
project. To switch to Moon Base One they would need to explain
clearly to Mars supporters all the reality conforming reasons.
Current Mars One followers ought to listen and support not criticise.
Negativity will not conquer realism. More than this they ought in
advance to encourage Mars One to become Moon One or Moon Base One.
Any Mars One training infrastructure already in place could be
restructured for moon simulation. The settlers must include the
right balance of aptitude and qualifications especially early on.
With earth return available then personality type will not be as
important.
If the public are
properly informed of its significance then the mission could be
funded in a partially similar manner to Mars One. Serious backers
need not mistrust the far fetched. Reputable aerospace companies
need not fear potential embarrassment. Let there still be a
downgraded reality TV element to it that is mindful of the human
attention span and respectful to the potential risks but concentrate
on serious backers. In additional to Moon Base One settlers, think
ahead to outsourcing peripheral lunar facilities to aerospace
companies. Think further ahead to collaboration with international
hotel chains to provide guest facilities. Clearly they would be
guests with deep deep pockets. To begin with there might be a
maximum of ten of them at any given time for stays of at least a
month. For them riskier elements like EVA's could be excluded with
day trips requiring small advanced lunar vehicles.
In keeping with the
Mars One mind set, a starting challenge of an extended duration
simple habitation module located in an equatorial region and visited
within a decade could be set. Contrary to common perception this
would not be easy to achieve for a private jump start organisation.
In practical reality even NASA would find it tricky although they
could absolutely do it if they had the funding. It's a big big
challenge but unlike Mars it's a potentially realistic one if full
scale resources and a “can do” attitude are thrown at it in a
strictly safety conscious manner. Realistic financing is vital. Also
there must be a specified aerospace company responsible for managing
any and all technical matters. A more grounded time frame would
extend the challenge to 15 years.
Analysis
of the Mars One “Intelligent Rover”
Mars One
claim the rover will be able to
- Autonomous travel to locate the most suitable location for settlement.
- Measure the amount of water in the soil.
- Prepares the surface for arrival of the Cargo missions
- Clear large areas where solar panels will lie.
- Move the 6 cargo landers to the chosen location on a trailer from up to 10 km away from the outpost.
- Unroll and lay down the thin film solar panels.
- Rely on own solar panels to recharge batteries up to and including first lander, a Life Support unit positioned in place with its solar panels deployed.
- Remove protective panels from the landers.
- Extract from a lander and assist with inflation of the Inflatable sections of the Living Units.
- Connect a hose that can transport water, air and electricity between the Life Support Unit and the Living Unit.
- Deposit soil in the Life Support System for water extraction and remove the dry soil.
- Deposits Martian soil on top of the inflatable sections of the habitat for Radiation Shielding.
- Transport the crew from their lander to the settlement.
The
proposed ability to physically perform these tasks is disconnected
from fact. In reality the integrated technology is not sufficiently
developed to create a rover that by Martian one third gravity
standards (38%) is robust, powerful but lightweight enough to be sent
there and pull heavy landers over realistic terrain and with
dexterity carry out its other assigned roles. Although it would
certainly be better than the recent Curiosity and tailored for
utility, its required technological state is simply too far beyond
for a mass constrained deep space rover. Such a design could
potentially end up taking a couple of decades of background
development and be the Mars rover equivalent of a expensive weighty
tractor. They plan to launch it in 2020. In short the rover concept
is a bust and by knock-on effect the entire near future mission
design concept is a complete bust. It would make no difference for
example if the technology is sufficiently mature to allow the Life
Support Units to slowly cook enough soil to stockpile enough water
and oxygen if the rover is incapable of gathering and delivering all
that soil to begin with. It would not be a bulldozer on a sandy
beach. Collecting the soil would likely be a heavy duty and
mechanical wearing task relative to its capability and the distance
to available deposits would only increase.
The Mars
Exploration Rovers used Solar
photovoltaic panels. Curiosity, 5 times as heavy as them with about
a 0.9 tonne mass needed a radioisotope thermoelectric generator. The
Mars One rover towing cargo landers with loaded masses of easily
several
tonnes over terrain is proposing
to use batteries recharged by solar power. For bad measure the light
intensity reaching Mars is about a quarter of that reaching Earth.
Based on illustrations it is expected to be not much bigger than
Curiosity.
At
best it could only be intentionally targeted to get the cargo landers
within 100m of each other at the chosen site assuming they have the
capability proposed by Space X Dragon V2 and aided by a Rover beacon
signal as specified. They may be mere meters from each other but
this does not mean a thing if they cannot be brought close enough for
umbilical connections. The strength and dexterity the rover would
need for this is a far cry from current technology even assuming the
site is as clean and level as could be hoped. Further away and the
rover starts running into terrain navigation difficulties.
Curiosity
for comparison has a specified top speed on flat hard ground of about
4 centimeters per second. Moving autonomously (no back/forth
telemetry delay) with hazard avoidance, it has an average speed of
less than 2cm/sec (NASA). Call it 2cm/sec which equates to 0.072
km/h. To move 1 km would therefore take it around 13.9 hours.
If the six cargo landers averaged 1 km distances from the
chosen site, that's 12 km of travel. Likewise if one lander was 6 km
away and the others were bang on target. Curiosity moving
autonomously say 16 hours a day would need about 10.4 days on flat
hard ground to cover that distance. In reality Curiosity has been
engineered by the Jet
Propulsion Laboratory to travel up to about 200 meters per day on
Martian terrain (NASA) so the 12 km trip would take at least 60 days.
Assume a
faster rover with better autonomous capability than Curiosity but at
the same time take into account intermittent solar power supply and
recharging, towing an awkward trailer (possibly self powered) and a
return journey laden with a several tonne mass landing capsule and
the same uneven terrain and perhaps soft terrain. Just because a
chosen path is not bolder strewn or over hills does not make it
simplified for a heavily laden vehicle of limited capability. It
would reasonably be expected to take at least the time that Curiosity
would need to autonomously cover the distance. That is ample
opportunity for a mechanically loaded rover and awkward heavy trailer
to get seriously stuck or bogged down or develop a mechanical
breakdown under stress. The low gravity will partially help by
reducing rolling resistance although it will equally reduce traction
force. The inertia acceleration forces are exactly the same for what
would probably be a very start-stop journey.
Mars One
actually state a landing accuracy of up to 10km. Averaging that at 5
km with 6 return journeys gives 60km which Curiosity would
autonomously need more than 300 days to cover on good ground. It
might arguably be better to replace any significantly off target
landers 26 months later rather than put the vital rover at risk
during expeditions to collect them. Although they are proposing to
use a next generation spacecraft like Dragon V2 that Space X claims
will have helicopter landing accuracy, that accuracy is really about
re-entry into the denser Earth atmosphere and not the approximate 1%
density of the Mars atmosphere. The entry would probably have to be
augmented by aerodynamic retardation devices which would be
consistent with the stated 10km accuracy.
The
rover is supposed to transport the crew from their lander to the
settlement. If they landed 5km away, the unloaded rover by Curiosity
standards might still take 2 or 3 weeks to autonomously reach them
followed by a slow return journey. Obviously they would need to walk
if possible.
Another
role of the rover that can be readily poked at is that of depositing
Martian soil on top of the inflatable sections of the habitat for
radiation shielding in preparation to crew arrival. This would
presumably mean a relatively small scoop at the end of the rover arm
to reach on top of the inflatables. It amounts to a notably large
volume of soil built up around them to start with. This requires a
countless amount of scooping that would have to be predominantly
autonomous. Besides from an excessive long term time requirement, it
is also liable to mechanically wear out the rover before the job is
done.
