The Return of Apollo? 653

hpulley writes "Bell bottoms are back, the Stones are still touring and Time has a piece on how NASA's _new_ space vehicle may actually be the return of a very old friend, a highly modified and modernized version of the Apollo Space Capsule. Manned spacecraft might actually leave low earth orbit again! Initially they'd fly with Delta and Atlas but more powerful boosters could be developed. We could go to the Moon again, and perhaps to Mars but I'm getting ahead of myself. Does that mean the last 30 years of space flight have been for naught? Expensive steps backward?"

    I'm a big fan of capsules to go into space. There's no reason why a capsule can't be reusable. They sit on top of the rocket, the best place for a payload. A rocket can be attached to the top for an escape option. They are a lot cheaper. On and on. NASA can still work on reusable boosters, without having to change the basic capsule design.

        Its a SHUTTLE, not a spacefaring craft. The point of the shuttle is to get into orbit and come back safely and reliably. How you you rather land back on Earth: parachuting into the ocean or landing smoothly like an airplane? The shuttle may not be the end all, be all for payload but it is a very good way to get HUMANS into and back from space. NASA invisioned taking a shuttle to a space station and from there boarding a SPACECRAFT to travel to the Moon or Mars or whatever.

          Those aren't the only two options. Russian and Chinese spacecraft parachute onto land. One could land smoothly like an airplane, without the ridiculous wings, by using a parafoil (indeed, such was seriously studied -- well, a similar idea Rogallo wing -- for the Gemini program). Or one could land smoothly yet vertically like a helicopter, Harrier jet, or Bell rocket pack.

            The real issue is not capsule vs. winged, the issue is whether or not you want to be able to accomplish a controlled, low-impact landing at a precise location. If you want to be able to re-use your spacecraft you pretty much have to be able to avoid bodies of water, large boulders, cliffs etc etc. A low-impact landing is important so that you don't break things when you land. As shown by the Shuttle, extensive refurbishment before every flight is a good way to make this too expensive. Almost as importantly, you want to be able to put down close to recovery facilities so you can get back to flying again quickly.

            Now, to get such a precise landing requires mass. If you use wings, they are heavy. If you insist on a capsule then you'll either have to have a big para-wing (heavy, complex to deploy, perhaps not so reliable), or landing rockets (heavy, and definitiely complex). Either way, you pay a mass penalty.

            The point I want to make is that you shouldn't be arguing over wings (at this point in the deisgn process), you should be deicing whether or not you need controlled landings.

              Clearly the most informed and intelligent post this far and deserves to be modded up. That IS the entire issue that many of the armchair aerospace engineers here seem to be missing. There was a MISSION REQUIREMENT to build something reusable and something that could with more assurance could be brought to very specific landing fields. There was also a requirement to be able to payload thing into space and BRING THEM BACK. This mandates pretty much everything that's in the shuttle right now.

              But as with most things, people aren't looking at how to design a different craft to meet those requirements, they are instead saying that the requirements arn't what they'd have done. Well see - that's why they're called requirements. If you have a mission that requires something, you have to build a vehicle that does that. To do otherwise would be like saying 'well helicopters are too slow so they get shot a lot so instead of making a helicopter we made a jet'.

              If you're going to debate things, at least debate within the parameters of the original requirements - not just your own desire to orbit the moon. While I would certainly argue that the shuttle and the saturn/titan programs should have been pursued in parallel, to suggest that only one of them makes sense defies reason.

                Actually, some of the current shuttle design came out of military dictates. They wanted to be able to access high-inclination orbits normally useful for spy satellites, as well as Vandenberg launch/return. These requirements drove the delta-wing design, specifically.

                The Vandenberg requirement went away. Spy satellites go up on expendables. Most science is close enough to equatorial that a simpler shuttle design would have sufficed.

        To land in a specific place? The Apollo capsules had a whole fleet spread across the Pacific to retrieve it and the crew.

        The problem with the Shuttle that flies today is simple -- the specifications, part NASA, part DOD, specifiy a mission that requires the use of attached booster rockets. Namely...

        1) The cargo bay is too large, and,

        2) The cross range capability is extreme.

        Why? The Air Force insisted that the Shuttle be able to, in one orbit, take off from Vandenburg AFB, put a KH-11 or similar sat into orbit (or retrive one) and land back at Vandeburg. The problem with this is that in one orbit, Vandeburg moves quite a way, since the earth is rotating.

        So, the huge bay was needed to handle the KH-11s, and the very large OMS engines were needed to get the Shuttle back to Vandenburg in one orbit.

        Drop these two requirements, and you can cut the OMS system by a half, the payload bay by at least a third, and, suddenly, you don't *need* the SRBs anymore. Indeed, the flyaway liquid fueled boosters become a possibility. You can drop one of the SSMEs off the craft, as well -- and lose the structure needed to hold it. And so forth -- or, even better, ride flyaways almost all the way up, and just have one SSME take you to orbit. Less OMS means less fuel tankage to deal with. And so forth.

        NASA wanted about 10 Billion in 1975 to build the Shuttle. They were told that they were getting 5. They said that they weren't even going to try -- it wouldn't work. DOD said that they'd be interested in the Shuttle as a military craft, with a few modifications and a couple of extra mission requirements, and wouldn't protest the extra budget money. So, the deal was made -- DOD got the huge cargo bay and the cross range capability, and NASA got the money to build it. Alas, they ended up with an impossible spec to build to -- and were only able to make it work with the SRBs and 3 SSMEs.

        NASA's biggest mistake with the Shuttle was taking that deal.

          I have in front of me NASA SP-2000-4029, Apollo By The Numbers by Richard W Orloff.

          From pp 305, Entry, Splashdown and Recovery table

          Mission - Distance to landing target point - Distance to recovery ship
          (distances in nautical miles)
          Apollo 7 - 1.9 mi - 7.0 mi
          Apollo 8 - 1.4 mi - 2.6 mi
          Apollo 9 - 2.7 mi - 3.0 mi
          Apollo 10 - 1.3 mi - 2.9 mi
          Apollo 11 - 1.7 mi - 13 mi
          Apollo 12 - 2.0 mi - 3.9 mi
          Apollo 13 - 1.0 mi - 3.5 mi
          Apollo 14 - 0.6 mi - 3.8 mi
          Apollo 15 - 1.0 mi - 5.0 mi
          Apollo 16 - 3.0 mi - 2.7 mi
          Apollo 17 - 1.0 mi - 3.5 mi

          Not one Apollo landed more than 3 miles from its landing target point, including Apollo 13 which had such troubles even getting home safely.

          Even if you double that miss distance to 6 miles, there are plenty of bays and lakes in the US which you could safely land in (12 mile diameter or more). San Pablo Bay or San Francisco Bay, any of the Great Lakes, 6 miles offshore basically anywhere, etc.

          The precision landing question is validly "Do I land on a runway or do I need a 5-10 mile wide open space?". But that's very different than "needing an ocean full of recovery ships". If it's accurate enough that I can land it in San Francisco Bay and recover it with a coast guard boat or tug, and Apollo was, then there's no big deal at all unless there's an emergency urgent deorbit away from the usual landing zone (a problem which Shuttle shares, and if it lands mid-ocean is SOL).

      Cramped quarters would be the least of their concerns:

      Getting back into space would be impossible with anything the size of the landers we used on the Moon. Anything like the Apollo hardware would be a one-way trip.

      Spending a year weightless would probably be cripling without some kind of exercise.

      I've read someplace that any Mars mission craft will need some sort of shielded "safe room" to protect the crew from bursts of radiation. That room alone would have to be atleast the size of an Apollo capsule. Also, while space is nearly empty, if you do hit something the damage to the hull could be massive, necessitating some sort of internal sealed room as well.

      Then, of course, there's the issue of food. A year there and back would be quite a payload on its own.

      Correct me if I am wrong, but the design plans were lost for the Saturn V rockets that powered the Apollo mission and none of the designers are alive anymore.

      I remember watching a documentary on Discovery Channel about how the design of the rockets were lost and the only thing left is a rocket or two on display at Kennedy Space Center (or some other Nasa Branch).

      That being said, this is why they completely abandoned the rocket for any future use, even though it was the most powerful one ever made, they simply didn't have the schematics to replicate it and I guess reverse engineering the ones on display isn't an option since they were of course hollowed and setup for display purposes.

        Simply google for "saturn v blueprints" and you'll find any number of sources debunking that "the Saturn V blueprints were destroyed" nonsence.

        The difficulty with reviving the Saturn V is not in the absence of the plans... those are safe and sound; but in the fact that the Saturn V was built with 1960's technology, most of the parts aren't made anymore, and many of the companies that made parts of the Saturn V don't even exist anymore. Furthermore, the production facilities that made said parts have long since been either shut down, or retooled. And NASA's own facilities, including the all-important Launch Complex 39, have long since been modified from Saturn V specs, for use with the shuttle.

        With all of the modifications to the design that would be necessary to start production on a new run of Saturn V's, on modern production lines, with modern manufactureing techniques, with modern components and electronics; it'd be easier just keep the basic math, but design an entirely new rocket. Certianly, it'd be a damn sight easier than finding vendors to recreate the '60's era parts to build new examples of the original design.

        But not a whit of the Saturn V design or data is "gone".

It has always been more expensive than the rockets it replaced and now with no more Soviet Russia (no jokes) we may be able to co-develop better booster technology. Russia has always had more powerful rockets and seem to be able to hit orbits more accurately than the US.

    Also, I honestly think this Single Stage to Orbit (SSTO) idea is foolish and stupid. Most of what I have read seems to indicate that a dual stage system would lower the cost per pound from USD 100k to about $6k and one could have two pieces that are reusable. To me that makes a lot more sense and by all acounts more doable.

    If we are serious about keeping the ISS up there, the next generation of space craft could save space to be a delivery and construction/repiar work on satelites and the ISS, then save expiraments for the ISS.

    • Hey, serious question - do you have something to back up that comment about the Soviets being able to hit orbits better than American rockets? It's something I've never even thought about, and it would be interesting to read more about that particular issue. Thanks!

    Not at all. Look at how much we've learned. The experience we've gained has been enormous. We learned that building a reusable winged spaceship is doable, but doing so on less-than-shoestring budget isn't the smart way to go. Once we've established a real infrastructure in orbit, in another hundred years or so, I think a reusable shuttle will again make sense. Right now it doesn't. It was supposed to be cheap. It's not. It was supposed to be safe. It's not as good as it could be. When you think about it, both Challenger and Columbia were doomed by the Rube Goldberg contraption that boosts the orbiter into space. The original design called for a reusable flyback booster as well. That was scrapped early in the program to save money.

    Not quite.

    We're finally seeing an admission from the aerospace establishment that the shuttle has failed as an experiment. Wings on space craft are essentially a burden. Mercury-Gemini-Apollo demonstrated that you could come back to earth -- even in a controlled fashion -- without wings. Shuttle had wings to meet an Air Force requirement on cross range capability. Now the Air Force doesn't even use the shuttle.

    So, the immediate future of vehicles intended to reach orbit looks like something that's been proven to work for both the United States and Russia. It's good to see people actually looking for something that works well.

    In other ways, though, this development is a further criticism of the NASA culture. Much has been reported about the suppression of dissent in the safety culture. This is one aspect of a larger suppression of independent thinking in aerospace culture. The lack of new ideas shows another aspect. The unwillingness to examine things outside the industry (the "not invented here" syndrome) demonstrates still another.

    New ideas and technologies thrive in free atmospheres. People are more willing to try new things. Good ideas get promoted. Faulty ones, even if held by people with power, are more likely to be challenged. For the aerospace industry to succeed, such a model must be embraced, not shunned.

      As mentioned briefly in the article, I would say that a *rocket-propelled* spacecraft with wings is a burden - it just doesn't make sense. However, if they could get something that takes off like a plane, then has a weaker rocket stage once it gets into the thinner upper atmosphere, that could be doable. Similarly, it could fly upon a very shallow re-entry, potentially preventing heat buildup, allowing it to land quite normally.

      Ultimately, I think something

      As Edison would put it, we did not fail. We found another way to not make a launch system.

      The shuttle was a good experiment, it was good to do it. However, it went on far too long.

      We kept throwing good money after bad, trying to salvage something from it, and we lost the gamble. In hindsight, it was a bad choice, but at the time (the 80s, early 90s), there was good reason to think it would work and we could salvage the program. It turns out the detractors were right. Now, let's move on. Back to the drawing

    The Russians have had to do space on the cheap for years, and their response was to stick with the Soyuz capsule, which has now been in service for nearly 40 years, and is one of the most reliable launch vehicles available, and certainly far less expensive than the shuttle.

    The last fatal Soyuz accident was in 1971. In 1983, a Soyuz rocket exploded on the pad, but the crew was whisked to safety thanks to an escape rocket, which is lacking on the shuttle. Given the choice, I would fly to space on a Soyuz any day over the shuttle.
    • Overall, the safety record of Soyuz is just fractionally better than the Shuttle, but it's not statistically significant.

      However, as noted, the Soyuz has not had a failure in over 20 years, and the current design has had no fatalities in at all.

      However, there have been some injuries during landing; sooner or later a fatality is not unreasonable.

      I don't see much to choose right now, although there are theoretical reasons for thinking that Soyuz could be somewhat safer.

    Now, a capsule alone might not make it to mars, but I doubt ANYTHING launched in one piece from earth would make it that far. Thus, the space station, the robotic arm - all that stuff is tech we needed (and still need) to prepare us. So what if we use a small capsule to go back and forth? You think we could have done what we did with Hubble using one of those lead kettles the FSU uses to shuttle people back and forth?

    The capsule system was inherently "modular" thus the inspiration for this bit of classic SF []. The only irony I find in all this is how accurate SF may have once again proven to be.

    Just don't tell anyone in Hollywood. After seeing what they did with Lost In space, I don't want even a chance of them getting hold of my fave SF series for one of their ticky-tacky plotless rehashes.

    The biggest problem with the US Space Program is that ever since we got to the moon they've been thinking small. Nothing really works well, or does much for you, until you scale it up to a decent level. Imagine if post-Columbus the various European nations had sent out a couple of row boats every few years...

    As with so much in life an investment is necessary to get the returns. To really benefit from space we must spend tens of billions on basic infrastructure. The ROI will be worth it. Big projects. A catapult for bulk loads would be a good start and possible with off the shelf technology.

    Even better would be a genuine attempt to build a space plane. All the half-assed three or four million dollar projects to date were nothing more than a waste of time.

    Best would be to immediately begin work on an elevator. Current best estimates say that an elevator could be built in about ten years, with a budget of six billion. Considering that the US is spending more than $8 billion per month in Iraq, I'd say we obviously have $6 Billion to spend over the course of ten years...

    When you think small, you get small results. I don't care if its NASA, or a private corporation, or a group of various space agencies and corporations, but we must begin thinking big or else nothing will ever happen.

    I'm really glad this is getting political room. The shuttle was a waste of money, material and lives from the day it was conceived, and the really sad thing was that everyone involved knew it.

    The Russian space industry is doing things right in a way that NASA have never managed. The Russians have focused on making spaceflight boring: so boring, in fact, that the last accident in a Soyuz capsule was in 1971. That's a safety record that makes the shuttle look a bit sick. It also helps that the cost is a tiny fraction of the shuttle; I worked out once that you for the price of a single shuttle launch, you could get the Russians to lift about four times the amount of cargo, plus people, in five seperate vehicles and still have change.

    From an engineering point of view, the lesson is painfully obvious: generalisation means compromises. The shuttle is trying to be a heavylifter and a man-rated lifter and a space station and a reentry vehicle, so no wonder it sucks. Much better to focus on small, simple vehicles that do one thing very well.

    The Russians have the best man-rated lifter in the world: the Soyuz. It doesn't do much, just takes people from the ground to LEO and back again, but it does it cheaply and reliably. They have the Progress, which I believe is the world's only orbital tug; it can launch, rendezvous with a vehicle, dock, undock and ditch safely, all by remote control. No-one else has anything like it. They have a whole selection of reliable heavylifters, although they are beginning to get competition in that area.

    If the Russians with their, ah, mostly broken economy can do it, why are the Americans having so much trouble?

    I just wish it were politically feasible for someone with money to just buy the entire Russian space industry, lock stock and barrel, and do some decent investment...

    Very shortly after the Columbia accident, a handful of old veteran astronauts, including Buzz Aldrin (likely the smartest engineer of the original astronaut groups) and John Young (first pilot of Columbia and the only astronaut from the original groups to fly Gemini, Apollo, and the Shuttle) were consultants to determine if Apollo technology could be used for a low budget to-and-fro human transport, as well as a rescue vehicle that could be mated as lifeboats to the International Space Station.

    This, I thought, was a great idea. After the Apollo 1 fire of 1967, the Command Module (CM) was drastically redesigned for safety and was a winning design throughout the program. It especially showed its toughness during Apollo 13. The CM was completely powered down after the accident, and, 3 days later, was restarted on its reentry batteries (with a tiny bit of juice from the Lunar Module), and no electrical shorts occurred despite the heavy condensation in the spacecraft.

    The Apollo CM design is tried and true. I prefer it as a lifepod, and NASA should reconsider the viablity of a combined vehicle that launches (with an orbiter atop) like a heavy plane to high altitude, where it serves as the launcher for the orbiter, which can use conventional and disposable boosters for the return trip. I still believe that glider vehicles make more sense and provide more abort options. Consider that Columbia and her sisters still have more ways to bail or return than a typical airliner.

    No aerodynamic vehicle can survive with a damaged wing, in any case, which is why a CM-style rescue vehicle and parachutes are appealing. I just don't like the use of old ballistics like the Atlas (which have a nice record of exploding). Man-rating rockets like these is a pain in the ass.

    Remember this? []

    The people here who bellyache about cost and danger and whether it should look like a plane or not, should look at this. It was a very serious contender for the X-33 program. It is a SSTO vehicle which is far more manueverable than the shuttle and far safer. And until an unfortuneate accident in 1997, the US had an actual working model. It is used to carry people into orbit. You want payload? Use a Detla V or an Arriane. You want a reusable work horse for people? Strongly consider reserecting this.

    Oh and BTW
    Space travel will be dangerous for the forseeable future. People will die. Maybe less people would die if we are more concerned about discovery and science and exploration than about cost. It's going to be expensive, but as one earlier poster pointed out, we are likely to get more out of a few billion spent on space exploration than we do out of the 8 Billion per MONTH spent in Iraq.

    The space shuttle was originallt speced out to be a REUSABLE spacecraft, just check the tires, top off the fluids, and it's good to go again.

    In part, that changed during it's design when it turned out that reusable in that sense just wouldn't work out for some of the parts.

    In other cases, we found out that in practice, various other componants were not really reusable.

    Instead, the shuttle was actually REBUILDABLE though it was mostly designed to be reusable.

    It probably would have worked a lot better had it been designed to be rebuildable from the start, and it certainly would have been cheaper than rebuilding a craft that wasn't designed to be rebuilt.

    For an example, replace the very expensive and fragile (as it turns out, too fragile) heat tiles and carbon panels with a cheap ablative resin. On landing, sandblast the char away and re-apply. Instead, since it had to be reusable, they went with the much more expensive and risky tiles and panels.

    Another interesting idea might be to leave parts of the thing in orbit. Each flight could dock with the service module and use it for the duration of their mission, then disconnect and leave it for the next crew. The part that returns would need to carry the expendibles, and have the self contained capability to return should something go wrong. That may or may not be useful (after all, space is a hostile environment, so unpowered equipment may not be durable enough to use again without serious work and time that is not available or worth it), but it's an interesting concept to consider.

    That would also shift the burden of redundancy somewhat since it would no longer be necessary to trade off capacity vs. more redundancy. In theory, the entire service module could be replaced in orbit if it came to that. Even life support provisions could be provided. At the end of a mission, just before seperation, any reserves that were not used in the mission could be transferred to the SM for use on a later mission.

    Another interesting option after further research is to actually use tethers to transfer momentum from the returning capsule to the SM in order to get what amounts to a boost for nothing.

    I don't think that NASA has done absolutely NOTHING in the last few decades, it's just that by sticking with the shuttle as-is, it hasn't been able to take much advantage of the things it's learned. A more modular system is in order so that they don't get stuck again with an all or nothing technology update. Capsule, booster and SM should be seperate projects which are updated and improved more or less seperatly.
