Debunking the Trillion-Dollar Space Myth

jfoust writes "When the President and NASA announced the agency's new space initiative, including sending humans back to the Moon and on to Mars, many news reports claimed that the plan could cost as much as $1 trillion. According to this Space Review article, that trillion-dollar price tag is a myth: it was based on erroneous data and analysis, in large part by a single Associated Press reporter, and propagated by many other reporters too busy -- or too lazy -- to check on the facts. Could this kill the plan before it has a chance to start?"

      I have always wondered, where/how exactly is all that money spent? Why does it cost so much?

      There's a story from the 60s, where a NASA technician wrote to his senator complaining about the bolts being used for the Apollo program costing something like $20 each when he knew he could go down to the hardware store and buy the same bolt for a tiny fraction of that. The senator raised hell and called in a bunch of NASA guys higher up in the food chain to answer before a committee why they were getting swindled on the bolts.

      The explanation goes like this:

      Early on in the Apollo program someone decided on what chance of failure would be acceptable- I think they chose something like 1 in a million. If your spacecraft has thousands or millions of parts, then even the tiniest probability of failure in the tiniest parts can really accumulate into something unacceptable. A random bolt from a random bin has a certain chance of failure- but if you knew exactly where the bolt was made, how it was made (and the quality control processes used), where the metal came from (or even which mineshaft of which mine it camer from), you could make sure you had a higher quality bolt with a lower chance of failure. Figuring all that information out, testing it anew once it comes in the door, and keeping track of that component from its manufacture to its installation on the space hardware (making sure someone doesn't just replace it with something from the local hardware store, or that it hasn't been exposed to anything that would degrade its performance) doesn't come free. It costs near $20 per bolt.

    Not really. You have to remember that Apollo was creating technology on the way. WE ALREADY HAVE THE TECHNOLOGY TO DO IT TODAY. What we need is the following:

    1. Heavy lifters for putting 100+ tons per launch into Low Earth Orbit. Energia Vulkan can do 200 metric tons. The Space Shuttle's engines can lift ~150 metric tons. We just need to remove the 117 metric ton shuttle out of the equation.

    2. A cheap method for taking people and light cargo (read: only a few tons) into LEO. A nuclear thermal powered space plane would do nicely here. If 100% of the hardware that goes up comes back down, we'll be in good shape. It's okay if it exhausts radiation as long as it doesn't exhaust radioactive isotopes. (The radiation will disperse within seconds, but radioisotopes hang around for years.)

    3. Space only, nuclear thermal rockets for missions to the moon and Mars.

    Here's the plan:

    Use your heavy lifters to throw a *useful* space station into Low Earth Orbit. This station should act as a construction yard and staging point. Construction crews can be ferried up via space plane.

    The space plane should only be launched over the ocean to prevent accidentally raining down debris on people. On return flight, it should come down over the ocean, then make a controlled flight back to the coast.

    At the station, the crews should construct the Moon/Mars craft and ready it for departure. The moon would be easy for an NTR rocket. A trip of a day or less would be feasible. If we've got our heads screwed on straight, we can use these craft to start mining the moon and nearby asteroids. This will allow us to return expensive materials to LEO for a very low cost.

    Once a Mars craft is built and successfully deployed to Mars (with its own NTR spaceplane on board for landing maneuvers), the station and other hardware should be rented out to commercial enterprises. These guys can then look at making a business out of the infrastructure in place and create a new space economy

    Cost figures:

    Engergia Vulkan Factory Retooling: 10-15 million

    Energia Launch: ??? (probably ~20-50 million per)

    Station Construction: 3-7, 100-200 metric ton modules built of traditional building materials. (No expensive composites!!!) ~$10 Million per module.

    Construction Equipment: ??? Fill in with standard metalworks and fab costs

    Nuclear Thermal Spaceplane: This should use as much proven technology as possible. Development would be expensive (Let's say $1-3 billion) but the cost savings per flight would more than make up for those costs.

    Nuclear Thermal Interplatery Craft: Depends on how large you want it. The bigger it is, the more costly it is. You could probably splurge and build it for $10 billion.

    If you add up the worst case figures, you're still not even approaching 100 billion. And once the infrastructure is in place, you now have a new economic frontier to explore.

    FWIW, this is not science fiction. We have all these technologies today. Unfortunately, fear of nuclear power combined with several non-space administrations (Nixon, Carter, and Clinton) have stopped us from making it a reality. Arguably, Apollo happened before we had mature technology, so that was a factor in things taking so long.

The Space Shuttle is one of the most efficient lift systems (but the Russians and US have done quite well with big dumb rockets--it just takes a lot more fuel). It takes approximately 3 million pounds of fuel to lift the very efficient 200,000 pound Shuttle into orbit. That is a fuel/payload ratio of about 15 to 1. To accelerate the Shuttle to escape velocity it would take another 3 million pounds of fuel, but it would take 45 million pounds of fuel to lift that 3 million pound to LEO. In other words, it would 15 SHUTTLE BOOSTER launches to get that escape fuel into orbit (assuming you lifted only the escape fuel and did not use the Shuttle ). Different design and fuel arrangements can reduce the fuel requirements a little, but this gives you an idea of why it took such a huge rocket to go to the moon. The Apollo Saturn 5 was the most powerful machine ever built. During launch, the Saturn 5 generated as much power per second as all the powerplants in America at that time! If you are planning a return trip, then you must also lift to Earth LEO and Earth escape velocity: 1) fuel for deceleration to orbit around the other world, 2) fuel to decelerate to the surface of the other world, 3) fuel to lift from the other world to low orbit, 4) fuel for escape velocity from the other world for the transit ferry , 5) fuel for deceleration upon return to Earth, either in one stage or two, that is to LEO and then to Earth. If you do it in two stages you can lift the landing fuel and vehicle to LEO without carrying it all the way to Mars, i.e., use the shuttle or a Russian lander to bring the Martianauts home from Earth orbit. Either way the return vehicle is going to be going 30,000 to 60,000 mph when it reaches Earth after falling 30-40 million miles into the solar gravity well. In other words, it is going to take more fuel per unit vehicle mass to slow the vehicle back down to Earth orbit velocity than it did to to escape from Earth going out! 6) and maneuvering fuel going and coming. That is why some are proposing to manufacture the return fuel on the Moon or Mars, so you don't have to lift the off-world return fuel all the way from Earth to Mars and then back. Of course it would take huge amounts of fuel to get the manufacturing equipment to Mars or the Moon to begin with. You can use modules and reduce the amount of fuel for each step: small Mars lander, small return vehicle to Mars low orbit, but I'll bet the Earth-Mars transit ferry will have to be at least 200,000 pounds. You can't expect the astronauts to sit in a telephone booth for four to six months. There are other design proposals to reduce the amount of fuel needed: ion drives, solar sails, aero-braking for Mars, etc., but IT IS GOING TO TAKE A SATURN 5-CLASS PROPULSION SYSTEM PARKED IN EARTH LOW ORBIT TO GET THE CREW TO MARS AND BACK. You save a lot of fuel with a nuke powered Earth-Mars transit vehicle, but it is no magic bullet. Nuke engines are heavy and only double the specific impulse over the the Shuttle LHLO. The limiting factor is the temperature tolerance of your propulsion system materials, not the energy contained in a fission reaction. It is still going to take huge amounts of fuel.

They can walk around and look at the terrain, and carry out tests on rocks, looking for signs of water or life, but all that can be done by robots. They can bring back rock samples, as the Apollo astronauts did from the moon, but that too can be done by robots. Samples of rocks from the moon were also brought back to Earth by unmanned Soviet lunar missions. It is sometimes said that the great disadvantage of using robots in a mission to Mars is that they can only be controlled by people on Earth with a long wait (at least four minutes) for radio signals to travel each way between the Earth and Mars. That would indeed be a severe problem if the robots were being sent to Mars to play tennis with Martians, but not much is happening there now, and I don't see why robots can't be left to operate with only occasional intervention from Earth. Any marginal advantage that astronauts may have over robots in exploring Mars would be more than canceled by the great cost of manned missions. For the cost of putting a few people in a single location on Mars, we could have robots studying many different landscapes all over the planet."

    This means that the Saturn 5 can carry 280,000 pounds into low earth orbit.

    So, one Saturn 5 launch is equivalent to SEVEN Space Shuttle launches. You only have to launch one Saturn 5 to carry the same payload to low earth orbit (say, in order to build the international space station) as SEVEN Shuttle launches.

The number of missions, originally predicted to be more than fifty a year, quickly fell to about eight while the operational and development costs rose as quickly as the vehicle leaving the launch pad.

    You either have to take your supplies along with the manned mission (*very* expensive), send them along in resupply payloads (not so expensive, but now you have a new class of failure modes) or make more during the mission (experimental, may not be appropriate for all classes of supplies).

    Furthermore the crew are going to have to be self-supporting for the duration of the mission. This means their vessel is expected to last for several years and the crew will need to have the capability to repair or replace failing components without calling back to base for special resources (resupply could be possible, but we are talking a lead time of at least several months so the crew would have to be able to improvise something to last them that long).

    Fault-tolerant, failsafe and reduntant systems, spares (or feedstock for spares plus manufacturing kit) all add mass and might well add new mission specialists (remember the 'Janitor' character from one of those crappy Mars movies a few years back?) to your mission profile.

    More mass means more fuel or more non-manrated resupply loads or more automated supply manufactories (if you adopt Zubrin's philosophy of 'living off the land'). All these things increase your logistical tail, which either cuts in to your scientific/flag-planting payload or increases the overall budget.

    Of course there are a bunch of infrastructure or basic capability costs to a mission which are pretty much fixed and which wouldn't change much between a Mars mission and (say) a Jupiter Moons mission or an Asteroid rendevous mission. But distance translates into time, time translates into logistics and logistics translates into money.

    Actually it occurs to me that this sort of problem-domain would make a good computer game - has anyone done something like this?
