They will setup a small reactor near their base and a much larger on will be setup miles from their base for a refinery.

      After construction of alpha base they will start constructing a larger habitat, soil and hydroponics farms from a slow trickle of refined metals being produced. Everything will be very modular and all metal will be recycled. We can expect chicken and fish farms for mean. They will also have pressure and heating units to produce oil from human, animal and plant waste; this will provide the material to produce plastics and a limited amount of fossil fuel for miscilaneous applications such as rocket fuel.

      But the main function of the base for years to come would be to produce massive amounts of metal and raw resources for construction of subsequent commercial colonies.

Add to that the fact that in his approach he clearly acknowledge? his limitations and based the designs on real current assumptions about the mission, and you have the result described in the article:

      I said, 'Look, this is our proposal for what a Hab would look like, and what a pressurized rover would look like, and we made certain assumptions based on how we operate deep submersibles, for example, in terms of how the manipulators would work taking samples and so on.' And [scientists from the human exploration and development group] said, 'Hey, this is neat! Thanks! If you ever want to get out of filmmaking, come here and hang with us.'


      As for the title "Doctor", it generally says nothing about the person. Cameron is not a Doctor, but he is a son of an engineer and he has a major in physics. The fact that he chose to pursue a career in filmmaking does not preclude him from being knowledgeable enough to make a reference design for human mission to Mars. On the other hand, his background in filmmaking actually makes him more qualified (I hope you won't deny the quality and realism of the sets and machines in Aliens, Terminator and Titanic).

It could easily cost $10 billion to design and build such a setup, plus a billion more to get it to Mars.

    The heat shields would also have to be pretty heavy-duty, since unlike Apollo or the Shuttles, these Mars vehicles are going to be traveling at interplanetary velocities. Because we'll want to minimize the astronauts' exposure to lethal doses of interplanetary radiation, as well as the amount of food and water needed to sustain them (costs a fortune to haul that stuff into orbit), their spacecraft is going to have to be traveling fast, and their landers are going to have to rely on the Martian atmosphere to slow them down.

    Their rovers would also need to be far more durable than the moonbuggy used by the Apollo astronauts, since most plans call for the astronauts to remain on Mars for weeks at least, if not a year or more. The Marsbuggy could itself cost in excess of a billion to design, and another billion to build.

    And since these guys are going to be there longer, in the hard radiation environment of Mars, they're going to need spacesuits that are far more durable, far better shielded against radiation, and far less susceptible to damage (from abrasive or chemically-reactive dust in particular) than the Apollo or Shuttle-era suits. Again, you could be talking a billion or more just to design and develop such suits, and heaven knows how much to build them. And with all that radiation shielding they're likely to be heavy as heck, too. Add millions more just to transport them to Mars.

    I haven't even touched on all the other tech needed to get the astronauts there and back again safely and quickly. Large, powerful nuclear reactors will be needed to supply them with electrical power and probably power their engines. I can't see doing this practically or reliably with chemical rockets

    I can answer that with a simple quote from Larry Niven: The dinosaurs went extinct because they didn't have a space program.

    Its a silly quote but its very true. The probability of humanity being destroyed or anhillating itself will drop dramatically once we have a self-sustaining colony on an extraterrestial object. Its like insurance for humanity in a way.

    The missions are incredibly complex. If any part of the mission fails, the chances of survival for the crew will be slim. Given the 50% success rate of Mars missions to date, this doesn't look so good.

    That's not true. The key trick with these plans is that you send the return vehicle first, and let it land and produce the propellant for the return trip before you ever launch the human crew. If you lose the return vehicle as it lands on Mars, it's a setback for the program, but nobody dies.

    The combined effects of low gravity and inadequate radiation shielding (space craft can't carry the extra mass requred) may mean that astronauts will be physically very weak or even ill by the time they reach Mars.

    Solar storms are a real concern, but best as I understand things there's little risk of prompt radiation sickness from the cosmic ray dosage on a Mars mission. Zero-g is a concern, but they could always use artificial gravity by spinning the craft.

    A two year mission to Mars will require that astronauts recycle almost all of the resources aboard, including oxygen, food, and human waste. To date, such technology has never worked well enough for a two year mission. Biosphere 2, for example didn't work for still undetermined reason and it was right here on Earth.

    I dunno about oxygen and water, but as I understand they plan to take all their food with them. While on Mars, there will be surplus oxygen available from the propellant production, so air recycling shouldn't be an issue there, and you can take a little extra hydrogen along to make lots of water.

You do things differently, your spacecraft are configured differently, your surface mission looks different, the time you spend on the planet looks different. So a certain set of fundamental assumptions had to be made and then we had to design everything for what it was going to look like."

    On top of that, you have not done your homework. On anything. Your post is so ignorant, you ought to do something really drastic to expiate your shame. I would suggest learning to study, and not posting on any subject that you have not studied.

    None of the components you listed in your message do us much good for a manned Mars exploration program. Take the Shuttle engines you list as one component. Only they aren't. They're needed in the (remaining) Shuttles. We'd have to build more of them to make a Mars mission possible before the end of the next decade - many, many more of them.

    Let's see, 1 launch window every 2 years, 2 vehicles per launch window, 4 engines per vehicle = 4 engines per year. Manufacture of High Pressure Fuel Turbopumps: "Production rate > 1 unit / month since first flight in July 2001 (STS-104)[1]. At the rate of 1 unit per month, you could have enough engines to fly a Shuttle every month and replace engines every 5 flights, send 4 vehicles to Mars every launch window instead of 2, and have about 3 brand-spanking new engines left over.

    It would take several launches just to get the gadgets to Mars to make liquid water and oxygen and hydrogen and everything else for the astronauts to use once they finally arrived.

    It would take one launch, carrying about 50 tons on a trans-Mars orbit.[2] The Shuttle orbiter weighs about 100 tons fully loaded; its engines are around 10 tons, leaving 90 tons for vehicle, payload and trans-Mars injection fuel. The required delta-V to get from LEO to TMI is roughly 4.3 km/sec. [3] Vacuum-specific impulse of an SSME is 452 seconds [4], or exhaust velocity of 4430 m/sec; the required TMI mass-ratio is 2.64 by the rocket equation. If you retained one SSME (modified to be restartable in flight) for the trans-Mars injection, you would need to start with ~53 tons * 2.64, or roughly 140 tons. This appears to be well within the capacity of a vehicle using 4 SSMEs and 3 SRBs to put into LEO.

    Then there are the cargo / habitat landers, which also cannot fail.

    Yes they can. You send them first, perhaps several of them, one launch window before you send people. If they don't land and work correctly, you hold the manned mission off for another launch window. If you send 3 and only 1 of them lands and works, you have one usable landing site; if 2 or 3 of them land and work, you have your choice of options. You can use the unused landers later, or for supply depots for long surveys.

    In-situ propellant production may have been demonstrated in the lab here on earth, but we don't know yet if it would even work on Mars. Right now we're having trouble getting simple robot rovers to function correctly, at $400 million a pop.

    You have some serious misconceptions about price tags here. The cost is almost entirely for research, development and engineering; manufacturing is a drop in the bucket. You could probably crank out rovers for a few million apiece now that we have the design.

    A small chemical plant is much, much simpler than a rover. The biggest issue might be filtering dust to keep it out of the machinery, and you would have a lot of trouble claiming that we don't have any applicable experience with filters.

    What you're proposing is that we drop a small chemical factory on Mars, along with an automated tractor and bulldozer to haul it icy rock for processing.

    No, that's your proposal. I'm proposing Zubrin's scheme of carrying LH2 to the site and processing it into methane and LOX via the reactions

    CO2 + 4 H2 -> CH4 + 2 H2O + heat

    H2O + energy -> 2H2 + O2

      That's nice. But that doesn't address my point. I didn't say it couldn't be done. I said it would take a lot of engines, unless you plan on somehow diverting the remaining Shuttles from their ISS missions to a Mars mission, or you plan to continue flying them long after they're scheduled to be decommissioned.

      Or unless you plan on using those Shuttle engines in some other launcher. Which is probably a good idea - the Shuttle engines are arguably the best part of the Shuttle program - but the R&D on a new launcher large enough to hoist those Mars payloads into orbit / off to Mars could eat up $10 billion or more. Much more if you want to build something that can haul those Shuttle engines back to earth so they can be recycled. Otherwise, you have to eat the cost of 4 Shuttle engines with every launch. How many flights will this adventure take?

      Wait a minute. You're telling us that this Martian contraption to manufacture hydrogen and oxygen and liquid water and everything else the astronauts are gonna need once they get to Mars is only gonna weigh 50 tons? An Apollo spacecraft at departure from earth orbit only weighed about 45 tons, and most of that weight was fuel. The LEM and capsule were tiny and fairly lightweight in comparison. It took a giant Saturn V to haul Apollo into orbit. Now you're saying that a rocket fuel / oxygen factory / storage facility and a bulldozer for Mars are only going to weigh 50 tons. I don't buy it. The Viking probe weighed 4 tons, not including fuel, and it didn't bulldoze rock and ice to manufacture and store rocket fuel. The Zarya module on the ISS weighs around 20 tons I think, and it didn't have to carry the equipment and fuel to slow it down and land successfully on Mars.

      > The Shuttle orbiter weighs about 100 tons fully loaded;
      >its engines are around 10 tons, leaving 90 tons for vehicle, payload

      So are you saying we'd launch on the Shuttle, or on some as-yet-to-be-developed vehicle. Because if you're launching on the Shuttle, it can only haul around 30 tons of cargo into LEO, if memory serves. So now we're talking at least two flights just to get your Mars rocket fuel factory into orbit and on its way. And if you're launch on some as-yet-to-be-developed vehicle employing Shuttle-derived technology, add at least another $10 billion to the cost of t
