Send the ISS To the Moon

jmichaelg writes "Michael Benson is proposing that NASA send the ISS to the moon instead of leaving it in low earth orbit. (While we're at it, we should re-brand it as the 'International Space Ship.') He points out that it's already designed to be moved periodically to higher orbits so instead of just boosting it a few miles, strap on some ion engines and put it in orbit around the moon instead of the earth. That would provide an initial base for the astronauts going to the moon and give the ISS a purpose other than performing yet more studies on the effect of micro gravity on humans. Benson concludes: 'Let's begin the process of turning the ISS from an Earth-orbiting caterpillar into an interplanetary butterfly.'"

    I like this idea on he face of it, but we are talking about a lot of work. The ISS, as presently configured, is in no way designed to stand on its own without regular re-supply... and we are a very long way from the moon in the sense of the energy it takes to keep punting supplies out to a lunar orbit.

    Right now, in LEO, getting a new toilet up there is still an effort that can take quite a bit of time and co-ordination. Food and other sundries depend upon lifting resources that cannot be generalized into getting a lot further out of our gravity well; we'd need a new generation of lifters to get that done (and, I suspect, more efficient and hopefully at least somewhat less polluting and poisonous propulsion methods.)

    Think over the ISS-related news of the last few years. The oxygen generator failure. The toilet failure. The bad elbow joint on the arm. The computer failures. Solar panel problems. All of these, and more, would have been that much more serious at lunar distances and energy requirements.

    Honestly, I get the very strong impression that the ISS is a piecemeal effort, not up to the quality required to exist at a significant distance from resupply and service; more than once there has been talk of having to abandon it. And that doesn't even factor in the dithering support at the political level — at lunar distances, we're talking huge increases in costs, and that will tend to amplify the politician's waffling in support, if indeed one could gain it in the first place.

    I would much rather see a serious effort put into a large enough work that it would have some chance at self-sustaining operation; a large hollow globe with cultivation, running water, and a manufacturing base. It'd be hugely expensive, but the vast majority of that would come up front, thus reducing the vulnerability to failed re-supply or loss of political support to kill it outright.

    Sadly, I don't see us doing that. We're a lot more likely to commit a trillion dollars or two (of our descendant;s money and interest) to reducing Iran to rubble than we are to seriously attempt to create a viable lunar space station.

    Don't get me wrong, I would love to see us actually get the heck off this planet and start populating the solar system, but the realities aren't just daunting, they're outright Godzilla-like.

Serious gravity at both foci means a narrow, fast elliptical orbit that keeps both foci occupied won't be possible without constant fuel consumption (a powered orbit), and history bears this out (the Apollo lunar insertion orbit looked more like a twisty figure eight, and if the craft didn't burn fuel at both ends, would have pointed well away from the Moon on the next pass). A big ellipse encompassing both points is effectively stable as you point out, but doesn't get close enough to be of any real use.
              The bigger problem is, the natural period of any such tight orbit doesn't precess at the same speed the Moon orbits the Earth. The Apollo orbit certainly didn't have a period of 28 days, nor did it precess so that the far end of it followed the Moon's motion. If it had, we could easily have sent supplies for a multi-month or multi-year stay on the Moon - anything that the astronauts in lunar orbit missed on the first pass would be back around again and again until they managed to recover it on some orbit, and it would have effectively accompanied them on their trip, at almost no relative velocity.

      Yes it would, if the container was not traveling at the same speed and direction as the ISS, but it happens at the moment of capture, not during the reeling-in period.

      If the container is moving slower than the ISS (which it would be, I'll get to the speeds in a second), then at the moment of capture the wire would impart an impulse force on the ISS, due solely to the inertia of the container. This would slow the ISS down, and would require a reboost burn to get it back up to transfer speed. Once the container and the ISS have reached equal speeds (some speed less than the original ISS speed and greater than the original container speed, proportional to the ratio of masses), then the ISS-container combination are now in orbit as a single object. The line of the orbit is technically at the barycenter of the two object system, and that barycenter will shift slightly as the container is reeled in, but we can safely assume that since the ISS is many orders of magnitude more massive than the container, the barycenter will be very close to the center of the ISS and will not shift an appreciable amount during reel-in.

      Now, speeds. The apogee speed of a lunar transfer orbit is approximately 11 km/s (24,600 mph). This is the speed the ISS would be traveling at close approach to the Earth, and also the maximum speed and minimum altitude of the orbit. The shuttle is capable of launching to an altitude of 217 nautical miles, which in a circular orbit is a speed of about 7.7 km/s (17,160 mph). The ISS would have to catch a wire traveling at a relative speed of 3.3 km/s (7,440 mph), and the rebound in the cable alone would doom the ISS, not to mention the tremendous stresses placed on both objects to essentially accelerate the container to that speed in the space of a second or so. Capture from two different orbits is simply not feasible; it's much safer to have both objects traveling at the same speed in the same direction for capture, and if you have to boost the container to a lunar transfer orbit speed, you have just used the same amount of energy as simply sending it to the moon.

The shuttle & ISS fire their engines to alter their orbits and nudge themselves around, but once the shuttle is in orbit, it ALREADY has to be going in the right direction at the right speed to eventually rendezvous with the ISS. If there were another space station at a higher altitude, the current shuttle couldn't visit the ISS, then go visit space station #2... at least, not without refueling somehow, because it doesn't carry enough fuel to radically alter its orbit to a higher destination.

Think of it as driving up a road along the side of a mountain in a car with mostly-empty gas tank, with *just* enough fuel to make it to the top... then using that final bit of gas to turn around, and coast all the way back down the mountain. If the shuttle encounters a serious problem en route to Hubble, it doesn't have enough fuel to reach the ISS, and no spacecraft already docked at the ISS has enough fuel left to reach the imperiled shuttle, so there's no metaphorical "tow truck" to rescue them.

      It's also the reason why spacecraft have to rapidly accelerate to multiple Gees, instead of taking off like a jet and just circling the Earth over and over, getting a little higher each time. When the solid rocket boosters are ignited, they burn in a predictable way, but there's no way to gracefully throttle them "up".

      if you're doing it from an asteroid you capture then you have to have a refining capacity on the station as well

      You'd want refining to be done on the moon, regardless of where the raw materials were obtained from. Once refined, again, up by mass driver. Refining is messy, power hungry, and space-consuming, but essentially simple, such that it doesn't require a lot of sophisticated support. Just large structures and large material moving machines. What you want on the space station is manufacturing, not refining.

      a telescope probe alone would require the ability to manufacture high precision lenses, propellants, batteries, computer parts, not to mention the frame itself). Chances are you wouldn't be able to do all of that realistically and you'd have to ship most of the raw materials up from Earth, but if you're doing that you might as well just manufacture the thing on Earth and launch it from there.

      I don't think batteries in the classic sense have much of a future. You're looking at little fission reactors, solar accumulators, ultracaps, that sort of thing. No reason to think this stuff can't be manufactured in a hollow shell. There are *many* reasons to do this, not the least of which is the elimination of the gravity wells, but others include ease of handling large components in a low-G environment, unlimited storage space, zero environmental concerns, unlimited energy supplies, zero weather concerns, ease of shielding in a hollow rock, the ability to have loose and flowing water, agriculture, trivial flying machines... it's really quite a list. Also, making lenses in space has many advantages, likewise in lower gravity. Also (sorry), in space, one can take advantage of many (relatively) small lens designs which have huge advantages over single large lenses. Same thing for radio telescopes. There's a lot to be said for a design that can take advantage of dispersion over a few million square miles without getting in anyone's way.

      Maybe if you had some sort of big mass driver to reduce the amount of propellant needed to get the satellites started on their journey, but you could put that in Earth orbit

      Well, mass drivers need something to push against. You put one in orbit, it sends a payload one way, it'll go the other way; you'd have to shoot in alternate directions or you'd be in deep trouble pretty fast. You also need a *huge* power supply, something much easier to put together on the lunar surface where the raw materials abound.

ISS orbits at 7.68km/s, so an off-the-cuff calculation would be 2*sin(28.1/2)*7.68km/s = 3.73km/s of delta-V about half the energy of launching it all in the first place. If my assumption is wrong that at some point of the year ISS is only off 28.1 degrees from the ecliptic, and you have to go the full 51.6 degrees, that's 2*sin(51.6/2)*7.68km/s = 6.68km/s - almost as much energy as launching it all. This also assumes that you can do the course correction ballistically - with an ion engine it'd take dozens or hundreds of orbits instead of a partial one, so the math would be completely different. With a 4500m/s exhaust speed chemical engine (f.e. the SSME), 3.73km/s delta-V requires a 2.26 fuel-to-final-mass ratio. If you didn't need to increase the mass of the ISS at all for the rocket engines and fuel tanks, then you'd only need 1070000kg of fuel. A Saturn V can lift 118000kg to low earth orbit, so you'd only need 9-10 successful lifts for the fuel itself. Should be a piece of cake.

      If you're going somewhere else with the ISS, then you wouldn't do that change at low earth orbit - higher orbits are slower, so it takes less delta-V up there.

If you got to the point where you needed any kind of facility to support significant space based fabrication, you'd need it because you're putting a lot of stuff into orbit.

    A fast boost would stress the system. A slow boost would put astronauts in the Van Allen belts for extended periods, which dangerous to astronauts and probably also to onboard electronics. If the slow boost is manned, there is danger, if unmanned, there would be no one to fix any problems.

    Oh, and the inclined orbit for the ISS is not the same as the inclination of the Lunar orbit, so it will take more energy to get the ISS there than a simple 2-D calculation would indicate.

    As a space physicist and engineer, I praise Mr. Benson's enthusiasm for space exploration. However, I feel compelled to explain to him and the millions of Post readers he was allowed to mislead why his idea to send the International Space Station (ISS) on interplanetary jaunts is wholly unrealistic, and frankly, impossible.

    For one thing, the shielding, wall thicknesses, and many other design aspects of the ISS were chosen to protect crews from the worst-case radiation environment known to exist throughout its present orbital environment. The ISS spends its entire time wholly within the protective cocoon of the Earth's magnetosphere, a complex electromagnetic structure generated within the Earth which also happens to protect the Earth from most forms of high energy cosmic rays and other ionizing particles. The ISS design is wholly unsuitable for long-duration jaunts outside this region and could not easily or practically be changed at this point to accommodate a different environment.

    Secondly, Mr. Benson's proposal to simply connect engines to the ISS and launch it away from Earth and onto interplanetary trajectories completely ignores the fact that every source of propulsion he cites would impart accelerations, even small ones for certain scenarios, that the ISS structure, joints, and arrays simply cannot accommodate -- the structure would simply exceed design tolerances under any source of thrust sufficient to launch it out of Earth orbit and on a transfer trajectory around the Sun to another Solar System body. Moreover, even the low-thrust ion engines Mr. Benson cites (actually, low "specific impulse," but that's another lesson...) would be unable to launch the ISS onto a transfer orbit to another solar system body, and certainly not on any reasonable timescale. It would be, perhaps, years before Mr. Benson's hypothetically-suitable ion engines could impart enough added velocity ("delta-V" to engineers) to move the ISS into an appreciably higher orbit, much less on a suitable trajectory to another planet in our Solar System. The ISS would require thousands of miles per hour of additional velocity to be placed onto such an orbit, regardless of the engine type used.

    Thirdly, Mr. Benson's essay completely ignores the fundamental fact that even the most efficient transfer orbit between Earth and, say, Mars, requires at least 8-9 months each way, not to mention the time spent actually DOING anything once there. The ISS is simply unable to hold enough food, water, air, and other "consumables" for any sized crew for the duration of any mission of the type Mr. Benson has in mind. And "direct" trajectory missions that ignore the more efficient transfer trajectories require so much acceleration that the ISS would simply flex and buckle were an attempt made.

    Forth, the amount of power the ISS solar arrays can generate is fundamentally tied to the solar energy received on their surfaces. Some of the interplanetary bodies Mr. Benson proposes visiting are at locations too far from the Sun for the arrays to generate enough power to operate systems on board. For example, the ISS solar arrays at Mars would receive only about half as much solar energy per square meter as they do at Earth. The ISS simply cannot accommodate hanging enough "extra" solar panels on its structure to make up for the difference, and wiring in new, additional power sources would require wholesale redesign of the ISS.

    There are about a dozen other significant reasons why sending the ISS on interplanetary missions is completely unfeasible from a technical perspective, and which time an space prohibit me from addressing here.

    Mr. Benson's claim that "...there are good answers to all these objections..." and his attempt at preemptive criticism of "skeptics" -- as well his claim that NASA is not "particularly welcoming to outside ideas" -- does not obviate the laws of physics, engineering limitations, much less the laws of astrodynamics and the hostile environment of our solar system.

      You wouldn't necessarily have to move it in one piece. You could break it down in to its original pieces and reassemble it in lunar orbit. I wager you could even land some of the modules on the moon if you had a transfer vehicle and a lander with the volume and power to handle them. All those pieces were designed to withstand a shuttle launch with multiple G's though you are correct assembled they weren't designed for that.

      You would just need an orbital transfer vehicle with a cargo hold similar to the shuttles.

      "For one thing, the shielding, wall thicknesses, and many other design aspects of the ISS were chosen to protect crews from the worst-case radiation environment known to exist throughout its present orbital environment."

      You could in theory build bricks on the lunar surface, send them up to the ISS and bolt them on the outside of the habitable module. Someone with better math and physics skills than me would need to tell us how thick they would need to be to shield from the solar wind and cosmic rays.

      It would be a major engineering challenge to design a way to bolt them on the ISS and there are probably all kind of corners where you couldn't bolt the necessary thickness of material without running in to things or covering over important items that need servicing. Also not sure how the structures and gyros would hold up to increasing the mass by a huge multiples. It would be an interesting exercise to solve the same shielding problems you will have going to Mars.

      If you actually landed them on the surface you could bury them, which I assume they are going to do for the lunar station modules anyway though again reaching things that need service would be a problem if they were buried.

      It would be a lot easier to lift the necessary shielding from the moon than it would be Earth.

      It would make more sense to recycle the ISS instead of letting it burn up and having to lift new modules from Earth for a moon station. Certainly some engineering thought would be required on the numerous issues you would encounter. Another concern is how much life the components have left in them. Some of the pieces are designed to only last a few more years (2015? I forget). It sure would be nice to reuse those big solar arrays if nothing else.

      Wrong. Ion engines are characterised by being low thrust high specific impulse. Specific impulse being the thrust that an engine can provide per unit of propellant. Ion thrusters do staggeringly well here because they have such high exhaust velocity, but low exhaust volume.

      "Mr. Benson's hypothetically-suitable ion engines could impart enough added velocity ("delta-V" to engineers)"
      Again you are making the mistakes you claim others are, you are trying to sound smart and failing. Velocity and delta-v are indeed 2 different concepts; however there's either a language or concept problem you have here. Delta-v is a measure of the change in velocity needed. Mission parameters are often discussed in terms of this delta-v because it is a handy measure. e.g. it might take a delta-v of 20km/s to stage a mission to mars; and this tells you a lot about the performance requirements of your spacecraft and the amount of fuel it needs without telling you about its velocity at any moment. The velocity in this case simply dictating the travel time, which may be of less interest.
      However it is perfectly valid to talk about an engine adding extra velocity, just and it is valid and more normal to specify an engine/propulsion system/spacecraft in terms of delta-v. However velocity is more comprehensible to the layman and no less correct for this case. I welcome pedants of poorly informed science articles - this one being a cracker - but the strength of your arguments against this article are undermined by your malformed attempts to pointlessly and incorrectly nitpick.

      "Secondly, Mr. Benson's proposal to simply connect engines to the ISS and launch it away from Earth and onto interplanetary trajectories completely ignores the fact that every source of propulsion he cites would impart accelerations, even small ones for certain scenarios, that the ISS structure, joints, and arrays simply cannot accommodate"
      This is one I am unsure of: How is the ISS going to be imparted stresses beyond that imposed by the thrusters? How is this thrust going to be of a magnitude or vector it wasn't designed for (bear in mind that the ISS was designed to support the stresses of the re-boost procedure, an Ion engine will be significantly less thrust than this procedure, all be it occurring over a longer time frame).

    A lunar orbiting ISS would, even if we can't use it today, be an investment in the future.

    Thank you for pointing this out plainly. One of the aspects of space exploration/development that always seems to get pushed to the side is concept of recycling. The sheer expense of getting mass out of our gravity well, even if not very far out, seems to dictate to me that once it's there we should be making every effort to keep it there.

    I don't necessarily agree that the ISS belongs in Lunar orbit. I think we are still a lot further out from doing anything useful on the moon than it's politically expedient for anyone involved with the space program or running for office to admit. Talk of a Lunar base is quite frankly silly at this point. When we can actually build and run a self-sustaining habitat or at least one that is nearly so, that's when it becomes time to look at a lunar base. In the mean time though, I can see the ISS still being put to other uses that would be preferable to just mothballing it because it has fulfilled its original mission.

    How many satellites are currently in orbit that have ceased functioning? How many are allowed or even directed to re-enter the atmosphere to burn or crash? Even if the only thing that they are useful for is raw materials, it seems downright wasteful to me to expend the resources to get them into orbit only to later let them indefinitely lie dormant or be destroyed. I think a better use than moving the ISS to a Lunar orbit would be to re-purpose it as a management base for a satellite graveyard/repair station.

    One of the key factors to progress in space exploration and development, at least in my opinion, is to make it profitable at least a lot less expensive. Make it feasible for technicians to not just make minor repairs but outright rebuilt satellites already in orbit. Once again the concept of recycling becomes key, but at some point the ROI of sending a team of engineers up to work in a satellite repair station exceeds that of simply throwing more material at the sky.

    I'm sure I'll get flamed now over my ignorance of the actual intricacies of what I am suggesting and I'll admit a distinct lack of hard information regarding the costs and probably many of the secondary and tertiary issues as well. What I do know for certain though is that any significant space development will involve recycling and re-use on a level that we don't even approach right now and that being able to actually manufacture things in space will be fundamental.

    This is one of the stupidest ideas I've read. I don't know how it made it to be news.

        The ISS is designed for one thing, to float around the earth.

        It isn't designed for radiation. It's doubtful if the electronics or the crew would survive through the Van Allen belt.

        It isn't designed for sustained flight. It's designed to be bumped around very (very) slowly between orbital altitudes, not pushed for long distances.

        It isn't designed for long term flight. It doesn't carry sufficient supplies to have a crew that far away.

        In an emergency, they'd be screwed. Their evacuation plan involves the Russian resupply modules, which are fine to drop from the ISS in orbit, not push out from the moon and pray. Their reentry velocity would be WAY over what it is coming from the ISS, since they'd be falling towards the earth the whole way. The resupply modules don't carry enough fuel to do the complicated maneuvers that would be required to decrease their velocity enough to survive.

        Resupply would be virtually impossible. Sure, we send things up to the ISS now. The ISS flies at between 278km to 425km. The iner Van Allen belt extends from 700km to 10,000km from the earth's surface. The outer Van Allen belt extends from 20,000km to 65,000km. The moon is at approximately 384,000km (average) from the earth's surface . So, the resupply ships would be flying 1000x the distance.
    With the moon landings, they targeted an object 3,400km wide. To resupply, they'd be targeting an object 58 meters wide. While I'm not going to suggest it's impossible, it's just not within the abilities of the infrastructure that we have right now. By the time we had just the resupply infrastructure built, the ISS would be ready to retire (or have already been retired).

        And lets not forget pesky things like solar flares. The ISS does over 15 orbits of the earth per day. With a little good solar forecasting, they can put the earth between the ISS and the sun to avoid the radiation burst. Lounging around between the earth and the sun on a direct course for the moon, they don't have that luxury.

        All the ISS navigation is done based on it's gyroscopes and earth based telemetry. If you're not near the earth, all of the Earth based stuff is pretty much worthless. They'd need to establish moon based tracking systems.

        I'm sure I missed a few finer points there. I'm not an astronaut, nor do I work for NASA. I've just been paying a lot of attention for the last 30 years or so. It's something about being able to see launches from the front door of my house that may have gotten my attention.

        I like the idea as something to do in the future. They *SHOULD* put a platform in a wide orbit around the earth and moon, which would be a significantly better way to not only move crew and supplies between the earth and moon, but give a nice neutral launch site mid trip for further exploration. The platform should have a much higher mass, better shielding, room to process sustainable supplies (plants to grow food and process air), and enough mass so it could tote along other craft, rather than being pushed long by other ships on occasion.

        A future platform would be an awesome (like invoking awe, not like totally rad) feat, which would help guide us towards future longer range space travel.

        Unfortunately, I don't see that ever happening. All the space agencies are a politically wrapped money pit, that spend more money talking, and less time doing. A well focused, unburdened effort would do us wonders. And yes, I volunteer to run NASA, if they can specifically block it from ALL political and government intervention. :)

    The whole concept of manned space flight is one of romantic appeal. There's no compelling reason other than that for us being out there. Probes, landers, and rovers can do the science bit far more cheaply than sending a manned mission. The concept of an off planet outpost so that humanity can survive the next planet killer asteroid/comet strike is laughable. We can't even get a stable artificial biosphere happening on our own planet. The only reason for us being in space is to prove to ourselves that we can.

    Having said that, the ISS should have been tasked as an assembly facility from the start. It is, in my opinion, a major planning flaw that it cannot serve that function. As was mentioned elsewhere, the ISS has the Dextre robotic arms, the capability for EVA, and a fairly roomy plain clothes environment. All it's missing is floodlights.
