Astronauts Face Bleak Odds For Spaceflight

Abhishek writes "According to a Space.com report, Astronauts at NASA fear that they won't be able to fly until 2015 and that, for some, would be too late. The space shuttles that NASA have are almost at the end of their lifetimes and any shuttle can take years to be built. Though almost everybody is involved in some way or another in looking after a shuttle, only a lucky few actually gets the chance for a ride."

To go into orbit you need to achieve a speed of about Mach 25 (Spaceship 1 was nowhere even close to orbital velocity). Rocket technologies today make sense in accomplishing this by minimizing the weight of the spacecraft and maximizing the weight of the fuel.

      I can think of a number of advantages.

      The first is that you don't have to plow through the atmosphere. Air pressure increases with speed and decreases with density as you rise, which means that the shuttles have to throttle back their speed until they are high in the atmosphere to avoid having the shuttle come apart. Then they accelerate as fast as possible. This point is called max q. (q=dynamic pressure) Basically your shuttle is idling along until it reaches this height. If you take the craft up to this height first using a plane instead of a booster, you're avoiding a tremendous amount of fuel wasting drag and are able to dramatically increase your thrust to weight ratio, increasing efficiency.

      The second major advantage is that you don't need to use liquid oxygen until you launch your rocket from the "booster plane". You can just use atmospheric oxygen. There is a tremendous weight (and thus fuel) savings right there.

      I'm going to quote someone more educated in this than myself for my third point:
      ...and this might be the best reason, is due to launch site azimuth restrictions. Currently, if designers want to place a spacecraft into orbit, they must hope that they can reach an orbit allowed by the azimuths permitted from a given launch site. (For example, Kennedy Space Center can launch to 29 - 57 degrees inclination.) If designers want to attain other inclinations, the must force the launch vehicle to perform doglegs, carry on-board propellant for plane changes, or choose a different launch site. By launching from an airbreathing vehicle, the launch platform can basically attain any inclination desired and avoid population centers. Allowing a spacecraft to direct inject to a desired inclination would either save major amounts of mass or allow much larger, more capable spacecraft.

      Now, you may not consider existing technologies "dumb", but anyone with half a brain should be able to figure out that they couldn't find a more inefficient method of getting that thing to the edge of the atmosphere if they tried. They've been running with the same design for how long now? This stuff was obvious to me when I was 15 years old! What were they waiting for?

      They've got an absolutely retarded budget, and are "supposed" to be among our very best and brightest.

      And ramjets would be great; unfortunately, we cancelled the program because of the premature Mars mission spending

      Err... no. The program was cancelled because scramjets are useless for launching cargo into orbit. The problem is, as you pointed out earlier in your post, the majority of the energy you need to get to orbit is in the "horizontal" direction. Most orbital flight profiles expend only 10% of energy getting into space and 90% gathering enough speed for orbit.

      What that means, in practical terms, is you lose too much energy to drag friction to make accelerating in the atmosphere worthwhile. You're better off just bringing the oxidizer with you.

      And there are three more practical problems to deal with. The first is all the extra complexity you need to get up to speed. A scramjet doesn't work until the craft is already moving reasonably fast (OK, that's weaseling, but "reasonably" depends on the design). So you'll need some kind of rocket booster to get it going even if you're at altitude. No big deal, right? Well, it turns out separating from a booster in the atmosphere is a big deal (I believe that's what caused the first scramjet test failure). This would be a major source of complexity (and thus cost).

      The second problem is materials. All that drag is gonna create a lot of heat, and your craft had better be able to deal with it. On top of that can you imagine going through an air pressure differential at mach 20? So your ship has to be able to withstand plasma temperatures and it has to be incredably tough.

      Also, the intake configuration of your scramjet is heavily dependent on air density. So it only works in a very narrow range altitude range. Too high and you don't have enough oxygen for combustion, too low and you burn up from the air friction.

      As near as I can figure, scramjets have only one application: long range, high altitude air-to-air missiles.

      And the point here is what? To build a smaller rocket. Why not just build a bigger rocket? The price of the fuel is just a tiny fraction of your launch cost, so just use more of it. The cost driver for rockets is complexity, not materials.

      The best solution would be a reusable VTOL rocket (not rebuildable, like the shuttle) It would require a very large rocket, since the ratio of fuel to cargo is large. But that would allow you to use the same rocket over and over without rebuilding it, since landing is virtually stress-free (from an engineering perspective) compared to the shuttle. See here for details.

      The DC-X project was our best hope for cheap access to space. The project had demonstrated the technology involved with vertical landing, and would have evolved into a vehicle you could use over and over with only minor inspections between flights (as opposed to tearing it all apart, inspecting everything, and putting it back together).

      But NASA killed it because they couldn't fund both it and the shuttle, and the shuttle was already proven technology in the sense you could already fly it to orbit and land it, while DC-X would have required a few iterations to make it work properly.

      It's no coincidence Carmack chose the design he did, and he could probably get to orbit reasonably soon if he wasn't trying to fund the whole thing out-of-pocket.

There is no airframe design out there capable of performing all of the following: horizontal takeoff, lift, flight and successful separation at supersonic speeds while in the atmosphere. You either separate at subsonic speeds like the Pegasus and similar Russian efforts or you do the full monty and get out of the lower layers of the atmosphere and separate there the way all missile launchers do (first stage is usually to 20km at least).

      If someone designs a separable airframe the technology to achieve Mach 3+ and 20km+ altitude is already there. Mig 31 in the reconnaissance version can do it, BlackBird can do it and these are 20 year old designs. While there is 22 Mach to go, if you look at the fuel expenditure doing 22 Mach from 20+ km altitude is likely to be about 10% of the fuel compared to doing 25 Mach from 0.

      And anyway, methinks that spaceplane booster stages are the wrong idea. I think it will be cheaper to build a rail launcher somewhere at 4-5 km altitude that fires a missile payload at 10-20 degrees up. Accelerating a few hundred tons to 600km+ for a very short trip is no big deal by modern technical standards.

      I wasn't talking about thrust at all - I was talking about efficiency. I've no doubt you can get enough thrust from a scramjet. The question is can you build a real spacecraft with a low enough drag that you'll use less fuel than you would by including the oxidizer and having no drag. I haven't seen even pipe-dream type designs that work on paper.

      And you seem not to be aware of how much of a propellant mass benefit you get; it's around a fourfold reduction in propellant if using hydrogen (ignoring drag), which gets multiplied many times over in terms of payload fraction.

      I'm aware - this is the purpose of using an airbreathing engine. It's just that I don't think it's enough to make up for the energy you lose to drag plus the extra weight of the engines. Also, let's say you actually get up to a high enough speed to get into orbit. Wouldn't you end up in an elypical orbit? So you'd need a rocket engine to put yourself into a circular orbit, plus you need some way to deorbit. You're going to build a ship with rockets and scramjets with low enough weight and drag to be more efficient than just rockets?

      It better be able to deal with it anyways, or you'll burn up on reentry. The only difference is that you need a different distribution - you need more on the leading edges.

      But it's not the same. Look at the shuttle's angle of attack when it enters the atmosphere. They try to get as much heat over the "belly" as they can, so it's not all concentrated on the leading edges. You wouldn't be able to do that with a scramjet. "more on the leading edges" is quite a thorny materials problem.

      No - too low, and you don't accelerate up to speed. What, are you picturing the scramjet climbing up, and then suddenly dipping down 10km after it's gained speed higher up? It's a flight trajectory; this is nothing new. Conventional rockets have to follow proper flight trajectories as well.

      As I understand it the physical configuration of the intake is relatively specific to a speed/altitude combination. In other words, you'll need different engines at different phases of the flight or an engine that can reconfigure the shape of the intake.

      It's not about fuel - at all. It's about structural integrity. The larger you make your rocket, the harder it is for it to bear its own weight. As rockets are build larger, you have to add more and more structural supports, which are really bad for your payload fraction. It's the same sort of problems that you encounter when building a skyscraper: the larger you make it, after a point it starts to become more expensive per square foot.

      As someone who designs next gen systems for a living perhaps some additional thoughts: 1) As rockets grow their structural weight does not balloon like a skyscraper. All rockets are mostly propellant ( if they are well made) and that propellant ( talking liquids here) has a vapor pressure associated with its temperature. Since it has to fill a tank at sea level this generally means that the O2 or H2 must have a vapor pressure around 15 psia- unless the propellants are subcooled. Otherwise the empty space above the liquid (the ullage) is pressurized with a gas of some sort. Maximum loads are not generally at liftoff- they are at max Q- roughly 40,000 to 60,000 ft where the ambient pressure is 5 psia or less. This means generally that you get 10 psid of internal pressure for free which acts to alleviate axial loads. Check out how much upforce is available in a cylinder that is 27 feet in diameter as on ET @ 10 psi. It is....large. Want more? Increase pressure. Also remember liquid head effects. SO! all modern vehicle designs make extensive use of internal pressure to stabilise primary structures. Also the tank diameter directly bears on the bending stiffness of the vehicle which is essentially a beam in bending - the main force being lateral aeroloads. We have not reached any sort of limit on rocket size - but transporting these massive structures does get costly and tedious. Anything over 18 ft is a pain due to transport issues. 2) Although ramjet/scramjet systems are certainly interesting their total operational time in an efficient trajectory will be measured in small numbers of seconds and the total impulse delivered by them will be small. And they are not zero weight. They want to fly at high Q for extended periods- just what the rest of the vehicle does not want- you are intensifying loads on everything else. 3) It is important to recognize that there are really two parts to a launch trajectory. The first is all about THRUST- getting the thing off the deck with at least 1.2 to 1.8 Gs. Otherwise you are accelerating too slow and pay a big penalty. You want to get up quickly to 5-6 G acceleration and HOLD it for some time. The optimal solution for this is fairly obvious by now- it is Lo2/kerosene and/or solids. With this big thrust and modern Isp's you can heave a high Isp upper stage up to around 1/3 to 1/2 of orbital velocity. THAT stage must strike a balance between thrust, dry weight and Isp. That balance is different depending on whether you are going to LEO or to the moon. Suffice it to say that BURNOUT WEIGHT is KING. Notice that this is not just dry weight- residuals are super important. Bungle those are your performance will suck. 4) Systems for getting tourists to LEO using PRACTICAL methods at reasonable cost ( might be a bit more than a million though) have been evaluated and can be executed if someone wanted them for real. Suffice it to say that they are unlike anything yet proposed- very cool. The real key to prices normal people can afford is RATE production. And there has to be a "THERE" there.

      Enough drag to offset a *fourfold* increase in ISP? Again, there's a reason why X-43 program was launched: Simulations have shown it performing exceedingly well. And I'm confused as to what led you to think otherwise.

      I haven't seen even pipe-dream type designs that work on paper.

      The X-43A worked on paper. It worked the same in real-world testing (actually slightly better). The X-43C works on paper. Undoubtedly, it would work equally well in the real world. Compressible flow simulations have gotten pretty darn good with modern turbulence models - and they show scramjets as performing quite nicely.

      Scramjets, *on paper*, show great performance (They were about on par with conventional rockets before the waverider concept was developed; the waverider has given a major boost to their predicted performance. You do know how waveriders work, right?)

      Also, let's say you actually get up to a high enough speed to get into orbit. Wouldn't you end up in an elypical orbit?

      Yes. Most designs I've seen call for 1/2 to 2/3 of the delta-V being provided by the scramjet. However, you've already got a rocket engine onboard the craft to accelerate it in the first place; most designs, therefore, call for either leaving the rocket on or having it restartable. Remember: a scramjet is a much simpler engine in design. It doesn't have oxidizer turbopumps or injectors, it only has half of the surface area, it works in a less corrosive mixture (because of the nitrogen), etc. Being able to use a simpler rocket engine at the expense of additionally having a scramjet would be a blessing on its own accord.

      plus you need some way to deorbit.

      You always need some way to deorbit if you want to get back ;) That's why, for example, the shuttle has the OMS.

      But it's not the same. Look at the shuttle's angle of attack when it enters the atmosphere.

      As I stated, the distribution is different. However, it's not as different as you're thinking, as the "belly" of a scramjet is one-half of the compressor, combustion chamber, and nozzle (the other half being the craft's own shockwave). It *needs* to be shielded just like the belly of the shuttle. Just like in the shuttle during reentry, the leading edges take the most intensive punishment (the scramjet attacks more head-on, but at lower speed, and heating is generally proportional to velocity squared). The tops are screamlined and relatively unscathed. The underside needs shielding almost, but not quite, as good as the leading edges. Etc.

      As I understand it the physical configuration of the intake is relatively specific to a speed/altitude combination.

      It is; that's what a flight trajectory is for, as I stated previously.

      While pressure is used to a great extent, it is unfair to pretend that structural integrity does not remain a critical component. In fact, it isn't rare to find somewhat tapered or staged tank thicknesses, such that if you were to take the rocket when full and turn it upside down, it would fall apart under its own weight.

      Increasing pressure doesn't necessarily help. Namely, because if you increase pressure, you have to build heavier tanks, and even pressure can only go so far. If we could just solve all of our problems by pumping in more helium, it would have been done long ago ;) Rockets have scale-up problems just like skyscrapers do - they're just different, because you're looking at a pressurized structure.

      If things were as you portray them, we could keep taking rockets and stacking more and more stages on top of them. We can't. In general, structural issues keep you from even just tacking more boosters onto an extant rocket unless it were either designed for it or you make modifications to the rocket to help support force of the boosters. Sticking new stages on top of extant rockets that weren't designed for it is, in general, right-out without significant modifications; the same goes for adding new fuel tanks. You simply can't bear the weight; the lower tanks or other load-bearing structures will fail.

      BTW, I'll second what you stated about desired thrust: You want high thrust during the first part of the launch, and high ISP during the second. Not only does a lower ISP not penalize you as much during the earlier stages as in the latter stages, but high ISP engines like LOX/LH have more problems with burnthrough when trying to operate in ground effect. I'm not too fond of solids because your whole rocket is your combustion chamber (imposing large-scale materials and pressure requirements) and you can't just turn the engine off, but you certainly don't need a staged pure LOX/LH rocket to get to space.

      Also, one issue that you didn't mention is that you can't just hold at a high G force. When running simulations, I'm always struck at how hard it is to keep a relatively constant G-force rating as high as you'd feel comfortable subjecting humans to, without going so low that your gravity losses become significant. Because most engines don't operate well at reduced power, as your mass reduces you accelerate unless you start turning off engines, which leads to significant thrust discontinuities.

      BTW - what were you referring to when you said "Suffice it to say that they are unlike anything yet proposed"? I've seen some interesting designs, mind you, and I'd be interested in anything you've seen.

      If you don't mind, I'd like to run a concept that I've been toying around with by you. Are you familiar with Black Horse/Black Colt? The idea was to have craft take off from the ground with minimal fuel, meet a refuelling tanker in the upper atmosphere, onload its oxidizer, and then head out to space. By taking off with a light load, they reduce structural and landing gear requirements, and by fuelling midair, they have the bulk of their oxidizer carried up on airbreathing power (it doesn't get much delta-V, but it gets out of most of the atmosphere).

      My concept was to take this one step further: Have an empty craft towed up to altitude (with fuelling lines attached) to it by a large, common commercial airplane. Some of the bigger ones can carry over 100,000kg cargo, and modifying a craft to tow isn't hard at all. At altitude, you fuel, detach the fuelling lines and tow lines, and it launches. That way, your whole craft is brought up to altitude on airbreathing power, and you can use a simpler aircraft to lift you up.

      Another concept that I've seen is to have your craft carried up, fully fuelled, inside the cargo hold, and dropped out of the back with a drogue chute attached to keep it stable until it launches.

X-43C was to accelerate from Mach 5 to Mach 7 (by the same models that correctly predicted the X-43A's flight), in its first flight, and possibly more in later flights. The followup to that, the X-43D, would accelerate to Mach 15 on its own power. At speeds up to Mach 12, it should be notably more efficient, in terms of thrust vs. drag, than conventional rockets.

However to make my point about scaling - the key thing is not the total dry mass of a particular stage but instead the mass fraction of the propellant compared to total mass. This flows directly into the rocket equation which relates the change in mass of a stage to delta V. In general the greater the capacity of a tank the greater its mass fraction if the design rules it followed are consistent. You can, of course, create poor designs with excessive L/D ratios and choose crummy manufacturing and materials to undermine this. My point is that scaling up volumes and masses is not in any way exhausted as of today. Most designers would agree that even further significant reductions will be available in the next ten years. There are a multitude of manufacturing and materials technologies that will aid this. Booster Engine throttling is commonly done on modern rockets and in general you can get around a 50% turn down on most engines before bad things happen.

      Here, let me give you a starter as to why these things cost so much.. does that sound good? Lets just cover a single small aspect of rocketry: Getting the fuel and oxidizer into the engine.

      There are traditionally two ways to get fuel into the engines: pressurized tanks, and/or turbopumps. Highly pressurized tanks are heavy, and are thus avoided for large rockets (there's usually a small amount of pressure to help maintain structural integrity). So, we need to look at turbopumps.

      Do you accept the cost of jet engines? You know, they're mass produced, and there are many producers and bidders, so they're quite competitive. Yet, new large commercial passenger jets engines still cost millions of dollars each.

      High performance turbopumps, like used in the shuttle have two stages; the top stage is a compressor similar to a jet engine, except of a performance level that makes a 747's engines look practically weak. The bottom stage is even more impressive; the high pressure turbopump is a centrifugal pump that spins at 37,000 RPM. Everything has to be incredibly lightweight, strong at cryogenic temperatures, reliable, and highly corrosion-resistant in the presence of incredibly reactive chemicals and at high vibrational loads. Making a jet engine isn't easy, but making a reliable turbopump is a truly massive engineering project, with a complex production process.

      However, it gets more complicated when you look at how they're powered. They use a network of feedback systems from the engine itself to spin additional turbines to run and to preheat the fuel and oxidizer. The turbopumps don't just spin themselves, but because performance is so critical, you can't just do what a jet engine does and stick a small turbine in the output stream to run your compressor. You can find some diagrams of the mechanism they use to do this online.

      The net result is a device many times the complexity of a jet engine *just to pump the fuel* (and another for the oxidizer), which is not mass produced. And you need several of these pairs of turbopumps (one for each engine) to launch a craft like the shuttle. Now, we're just talking about the *pumps* here. Want to get into more systems?

      If the Shuttle is a research program as you maintain then it has no business being used as a cargo hauler for ISS. You don't fly passengers and cargo in an X plane. Killing the Shuttle and forcing NASA to instead spend that money on a new vehicle would be a lot more useful than keeping it flying meaningless missions to ISS or useless orbital missions where they raise worms.

      Not really. Even if they had gotten pictures, the craft still couldn't have reentered. Besides, the concept of calling NRO was only established *after* the accident. Pieces of insulation fell off the tanks frequently, and had never done damage before; not just in the US, but in the USSR, too. And not only does it not "look" dangerous, but from an energy standpoint, it doesn't look that bad either. The problem was an unexpected property of the foam: that it tended to not compress at high speeds and thus delivered its energy in a single sharp impact.

      We have the Challenger disaster, which would have been preventable if NASA hadn't been in such a hurry to give Ronnie Reagan something to talk about in his State of the Union address (he got it)

      Pressure was part of it, but the engineers in charge of the call had the problem of insufficient data. They never would have launched if they thought the craft would blow up as soon as it took off. They did not have access to all of the studies conducted on all parts of the craft (of which there were *many*); one of the numerous studies conducted mentioned the O-ring temperature issue. O-rings had problems before, mind you - the problem was that they thought they had solved the problem by adding a redundant ring, when it turns out that at low temperatures the extra ring becomes ineffective. The last problem was statistical: one of the charts plotted all O-ring failures by temperature, but did not include successes. While there was no visible correlation in the chart, when you add in successes, you find out that every single low-temperature launch had at least one failure, while very few high temperature launches did.

Having so many Scout I & II missions over the decades, made it cost effective vehicle. Note, I'm not dissing the Scout, it was a truely diamond of a vehicle for NASA.

      Wrong. An insulin hexamer called T6 was developed in 1982. Real insulin in the human body, however, has three different hexamers. While we had been able to haphazardly produce the others (T3R3 and R6), we were unable to understand why it flipped forms (and thus how to control this). Of the three forms, T3R3 was the most desirable. In the body, it is carefully regulated by a series of proteins that control what form it takes. Because of the ability of insulin to slightly shift forms, its crystals tend to be rather disordered. The crystals brought back on STS-60, however, were large enough (over 30 times larger) that X-ray crystallography provided accurate structural representations.

      Modern insulin sold for diabetics is a more natural mix. They now use two zinc ions per hexamer to encourage and stabilize the T3R3 form. This provides a much longer time release and much more stable levels of insulin; while the old form was unlike what is normally found in the pancreas, the new form is a much closer analogue. Brand names are humulin, novolin, lletin, velosulin; it's also called lente insulin, NPH insulin, regular insulin, semilente insulin, ultralente insulin, buffered human insulin, extended insulin zinc, and a number of other names.

      The private sector still has a lot of work to do before it can really play with the big boys (in this case, government space agencies). It will catch up, but it's kinda like saying you're ready to start carrying passengers between New York and Tokyo because you can fold a piece of paper and make it fly. You may have re-discovered for yourself the principles of flight, but it takes a bit more expertise and experience than that to do anything meaningful with it. You're not quite ready to challenge Boeing or Airbus if all you've got are paper airplanes.

      A lot of people fail to appreciate the difference between what Rutan has done and what world government space agencies (not just NASA) do every day. It's not just about rocketing a guy to the edge of space and back again. It's about getting meaningful work done, which means the ability to carry large payloads to precise areas in orbit, then make it back again to a precise area on the ground. When you start talking about orbiting the Earth 100 miles up with a payload of 40,000 pounds, then you've got all sorts of issues to deal with. The private sector hasn't even started tackling those issues yet.

      Luckily, NASA and other space agencies have done most of the work for them already. But that doesn't mean they won't have to re-learn and experience everything for themselves - it just hopefully won't take quite as long to do it.

      (btw, this is not to take away from what Rutan has done - it was a great accomplishment. But it needs a sense of perspective - there is still a ton of work to do, and what NASA does is different by an order of magnitude.)

      2. the political winds change, and suddenly some new concept is the one and only true future of manned spaceflight

      The X-33/Venturestar program is a poster-child for the first outcome. NASA sunk 8 years and $200M+ into that program, and never even managed to get a flying half-scale demonstrator. Why? Because at the outset of the program they selected a vaporware Lockheed Martin concept that involved all sorts of sporty technology, rather than go with a more conervative design that might have actually stood a chance of working (like, for example, the Delta-Clipper program, which had already managed to produce a flying half-scale demonstrator in 2 years, on a 1/4 of the X-33's budget).

      The Orbital Space Plane is a good example of the second outcome. Everyone was excited about it for a while, and then all of a sudden capsules are the rage and OSP gets replaced with the CEV.

      It'll be interesting to see which way the CEV ends up going.

    So a few elite government employees will not be able to make it into space? Well, welcome to the world of the rest of us!

    You can mark this a Troll, but this is not. Why should we feel bad about the ambitions of government employees that are supposed to be serving us? Especially when they have taken so much of our money, and failed us so badly?

    The answer is: Yes, we're supposed to feel some sympathy for people who spend their lives training for an extraordinary and meaningful experience, but who may not see their dream fulfilled. No, we're not supposed to be completely callous to their aspirations.
    The blunt fact is this; the current astronauts aren't really in any different boat than any other astronaut over the last forty years. They knew the score going in.

    Chemical propulsion engines are not efficient enough for solar system exploration. They may be good for puting sattelites on the orbit, but certanly not usable for manned exploration of the solar system. Flying nuclear reactor with hydrogen used as reactive body is dangerous. But still it is possible to assemble it on orbit and start it from there (or from moon). In my opinion a greater obstacle, besides engineering efforts, is the radiation emitted by Sun. It will probably make it very hard to maintain chain reaction bellow critical point. Shielding with lead probably will solve that, though.

    The world ain't black and white. Back in the days when the shuttle was being promoted, Walter Mondale was one of the people saying it wasn't worth the money. Doesn't fit the stereotype, does it?

    History's more complex than the stuff we're fed on the evening news. Kennedy's hardly my favorite president -- I think his recklessness with the Bay of Pigs was just about as stupid as Bush II's Iraq blunder, and let's hope Iraq doesn't lead to something on the scale of the Missile Crisis -- but he chose the space program shrewdly, partly because it was a good crossover issue hand-in-hand with his "missile gap" militarism.

    Here's a tip back: Putting yourself in other people's shoes isn't a waste or a nuisance, it's a strength.

    I'm never going to go on the Lewis and Clark expedition, but having some sympathy for Meriwether Lewis, or understanding the guy a little, isn't going to make my life any poorer. Not even at this distance in time.

    Spending energy resenting astronauts for wanting to do something amazing, though -- now that'll only leave you diminished.

    Okay. I'm not sure why that means we shouldn't sympathize.

    We sympathize with amputees coming back from Iraq, don't we? They knew they were joining the military. (If they joined under Bush II, they sure should've known what that meant, too.) Somehow putting myself in other people's shoes has never seemed like a waste of energy -- whereas resenting people who aspire to something seems like it'll only diminish everyone involved.
