Astronaut Group Endorses Commercial Spaceflight

FleaPlus writes "Buzz Aldrin and twelve other astronauts have published a joint endorsement of commercial human spaceflight, stating that 'while it's completely appropriate for NASA to continue developing systems and the new technologies necessary to take crews farther out into our solar system, [the astronauts] believe that the commercial sector is fully capable of safely handling the critical task of low-Earth-orbit human transportation.' They are confident that commercial systems (which NASA already relies on for launching multibillion-dollar science payloads) can provide a level of safety equal to the Russian Soyuz and higher than the Space Shuttle, while strengthening US economic competitiveness. They also support the expected endorsement of the White House's Augustine Commission regarding NASA's use of commercial spaceflight — the Commission's final report will be released today." And here's the Augustine report itself (PDF).

      http://www.spacepolitics.com/2009/10/22/a-question-of-safety/

      The topic of safety same up Wednesday as well in a talk by Augustine committee member Jeff Greason at the International Symposium for Personal and Commercial Spaceflight in New Mexico. In the Q&A session after his speech, he was asked why the committee didn't endorse Constellation as the "most viable" option "even though from a safety and mission assurance standpoint it's clearly the best option." Greason said that safety and mission assurance was considered by the Augustine committee, but that goes beyond simply the choice of launch vehicles.

      "Launch is a relatively small contributor to the safety and mission assurance" of human missions to the Moon and beyond. "It is not negligible, it is not something you want to forget about, but it does not dominate the loss of crew probabilities." Therefore, he said, it was a mistake to focus on further increasing the reliability of a relatively small aspect of overall mission risk, particularly if those choices lead you to take out safety systems in other components that because of mass restrictions. "These are false economies in terms of safety and mission assurance."

      Greason was also skeptical about the probabilistic risk assessments used to estimate the safety of various proposed systems. Most launch failures are not from random types of events, he said, but instead failures of design, testing, procedure, and the like. "If it was built wrong, it doesn't work a lot of the time, no matter what you thought the probabilistic failure was." The only way to "buy down" those failures, he said, is though flight experience, which is why "real boosters" have lower reliabilities than estimated when they were "paper boosters" still in the design phase.

      "And the truth is, Ares 1 is, right now, a paper booster," Greason continued. "And the further truth is, its projected launch rate is extremely low, so it will never get out of 'infant mortality,'" that initial phase of non-probabilistic failures. "Even if Ares 1 were built exactly as planned, we would never find out whether its mature probabilistic risk assessment was or was not achievable as planned, because we would never get through the phase of life where we're supposed to work out all the teething problems."

      The first means that they simply refuse any plan that can't be done with a strong expectation of safety.

      The second means that its impossible to analyze the initial safety of a paper rocket, and personally I'd love to see the Senator try. You can analyze safety from a PRA perspective (analyzing likelihood of failed components), as opposed to unexpected failure modes, but the report points out that PRA failures have never brought down a manned spacecraft. Unexpected failure modes are just that, unexpected, and as such can't be analyzed properly.

      Actually, the nastiest safety issues with the Ares I are a direct result of the design decision by former administrator Mike Griffin to use a single gigantic solid rocket motor as the first stage. It turns out there's a really good reason (or rather, many good reasons) that nobody's used such a design for a manned rocket before.

      None that wouldn't have turned up in any other new rocket design.

      There are three big safety issues that appear precisely because of the choice of an solid rocket motor (SRM) derived from the Shuttle solid rocket boosters (SRB). First, thrust oscillation is a problem with solid rocket motors because of their design. The SRM has a chamber prior to ejection through the nozzle. Certain vorticies resonate with this chamber and this vibration is then transmitted to the rest of the vehicle.

      Now you may ask, if all solid rocket motors have thrust oscillation and the SRM is Shuttle-derived, why isn't the Shuttle affected? The answer is that it would be except for the clever way in which the SRBs are attached to the rest of the Shuttle stack. Effectively, both SRBs are attached to each end of a giant bar. The external tank only connects to this bar at two points which as I understand it are null points of the thrust oscillation vibration (which is very predictable). So as a result, little of the vibration is actually transmitted to the rest of the Shuttle. This only works because we have a pair of boosters that are attached only in a couple of spots to the rest of the vehicle. It doesn't work for the Ares I because the second stage has to be mounted on top of the SRM. End result is a great deal of vibration (how much we'll see in a few days). There are various solutions for dampening the vibration, but these cost mass or thrust. Neither is a problem with liquid propellant rockets like the EELVs.

      Moving on, the second problem is the aspect of the Ares I. It has a wide second stage and a narrow first stage. This is precisely a consequence of the choice of the SRM as the first stage. The problem is that since SRMs have to go through a railroad tunnel when they're being shipped from Utah, they cannot be wider than they currently are. So the Ares I has an increased chance of bumping the launch tower at launch due to wind gusts. The limited width of the first stage also limits the performance of the vehicle leading to the third problem.

      The third problem is that the launch of the Ares I has been made safer at the expense of the rest of the mission. This doesn't have much consequence for LEO missions since there is some performance margin to use up. But lunar missions are very tight on mass. So the performance loss from thrust oscillation mitigation or other problems comes by taking weight away from the payload, here the Orion vehicle. Further, the first stage is already as large as it can be, so there's no additional performance to be gained from the first stage. That means in turn that compromise of the safety of the Orion vehicle, namely removal of some redundancy of the vehicle, has to occur in order for the Ares I to lift it. Since for lunar missions, most of the risk is in the mission not in the launch, this means that we're increasing the overall risk of the mission merely to continue to use the Ares I.

      The Launch Abort System didn't even exist on the Shuttle or Saturn rockets. It may not be 100% effective, but it doesn't need to be to at least provide a measure of additional safety.

      This reminds me that there is a fourth safety advantage of other rockets than solids. In case of full rupture and conflagration of the first stage, a liquid rocket burns slower than a solid. That means lower heat on the escape vehicle and a greater chance of survival for the crew.

      There are much better arguments against the Ares I. Like why it needs to be done at all when it has similar capabilities to the Delta IV, Falcon 9, or one of the number of shuttle-derived concepts out there.

      This is my primary objection to the Ares I as well. There are two near future commercial rockets, the "EELVs", Delta IV Heavy, which flies now, and Atlas V Heavy (which would be based on a modification of the Atlas V which flies now). So we're ignoring rockets which fly now in exchange for paper rockets which as we've seen don't work as advertised. NASA should never be in direct competition with private launch services. It gives them too much incentive to undermine the competition.

      Oversimplifying a bit... Suppose combustion-chamber pressure surges a bit for some reason. That increases back pressure against the fuel coming in, which slows fuel flow. That reduces chamber pressure, which lets the flow pick up again, etc. There are also less direct interactions, e.g. greater chamber pressure means greater thrust and higher acceleration, which boosts hydrostatic head of fuel coming down from the tanks and tends to increase flow. Lots of feedback loops that might oscillate.

      Now, if the natural frequency of one of those potential oscillations happens to match a resonant frequency of the vehicle or the fuel-feed system... you get oscillation, potentially violent (several Gs), at relatively low frequencies, typically a few Hz. That's Pogo.

      The way to cure Pogo is to add some damping to the cycle, typically by adding a surge absorber to the plumbing -- just a chamber with liquid in the bottom and gas in the top, connected to the plumbing, so surges in pressure push liquid in and out against the gas pressure rather than being communicated to the engine. Modern rockets typically have such Pogo suppressors built in from the start; for example, the SSME has a Pogo suppressor in its LOX feed (LH2 is too light and too compressible to be much of a problem -- it supplies its own damping), and has never had a Pogo problem.

    For some reason the link for the Augustine Report seems to be going to a download for Windows 7 (Huh?!?), so here's the actual link (mirror).

    Here's the main report findings from the PDF:

    Summary of Principal Findings

    The Committee summarizes its principal findings below. Additional findings are included in the body of the report.

    The right mission and the right size: NASA's budget should match its mission and goals. Further, NASA should be given the ability to shape its organization and infrastructure accordingly, while maintaining facilities deemed to be of national importance.

    International partnerships: The U.S. can lead a bold new international effort in the human exploration of space. If international partners are actively engaged, including on the "critical path" to success, there could be substantial benefits to foreign relations and more overall resources could become available to the human spaceflight program.

    Short-term Space Shuttle planning: The remaining Shuttle manifest should be flown in a safe and prudent manner without undue schedule pressure. This manifest will likely extend operation into the second quarter of FY 2011. It is important to budget for this likelihood.

    The human-spaceflight gap: Under current conditions, the gap in U.S. ability to launch astronauts into space will stretch to at least seven years. The Committee did not identify any credible approach employing new capabilities that could shorten the gap to less than six years. The only way to significantly close the gap is to extend the life of the Shuttle Program.

    Extending the International Space Station: The return on investment to both the United States and our international partners would be significantly enhanced by an extension of the life of the ISS. A decision not to extend its operation would significantly impair U.S. ability to develop and lead future international spaceflight partnerships.

    Heavy lift: A heavy-lift launch capability to low-Earth orbit, combined with the ability to inject heavy payloads away from the Earth, is beneficial to exploration. It will also be useful to the national security space and scientific communities. The Committee reviewed: the Ares family of launchers; Shuttle-derived vehicles; and launchers derived from the Evolved Expendable Launch Vehicle family. Each approach has advantages and disadvantages, trading capability, life-cycle costs, maturity, operational complexity and the "way of doing business" within the program and NASA.

    Commercial launch of crew to low-Earth orbit: Commercial services to deliver crew to low-Earth orbit are within reach. While this presents some risk, it could provide an earlier capability at lower initial and life-cycle costs than government could achieve. A new competition with adequate incentives to perform this service should be open to all U.S. aerospace companies. This would allow NASA to focus on more challenging roles, including human exploration beyond low-Earth orbit based on the continued development of the current or modified Orion spacecraft.

    Technology development for exploration and commercial space: Investment in a well-designed and adequately funded space technology program is critical to enable progress in exploration. Exploration strategies can proceed more readily and economically if the requisite technology has been developed in advance. This investment will also benefit robotic exploration, the U.S. commercial space industry, the academic community and other U.S. government users.

    Pathways to Mars: Mars is the ultimate destination for human exploration of the inner solar system; but it is not the best first destination. Visiting the "Moon First" and following the "Flexible Path" are both viable exploration strategies. The two are not necessarily mutual

    1. Re:Summary of Augustine Report by FleaPlus · · Score: 1

      I really, really like the "Flexible Path Towards Mars" proposed by the Augustine Committee, which is detailed on page 40 of the report. For those unfamiliar with it, it stresses near-term exploration of a variety of targets in shallow gravity wells, ranging from Lagrangian points to the moons of Mars. I also rather like the table on page 41 of the report which describes the 8 different categories of destinations for Flexible Path (Lunar orbit, Earth-Moon L1, Earth-Sun L2, Earth-Sun L1, Near-Earth Objects, Mars Flyby, Mars Orbit, Martian Moons), and describes both possible ways to engage the public about each destination and possible scientific goals at each location.

      The quick summary of Flexible Path, from the report PDF (bolding inserted by me):

      3.5 THE FLEXIBLE PATH TO MARS

      3.5.1 Overview. In addition to Mars First and Moon First, there is a third possibility for initial exploration beyond low-Earth orbit: visiting a series of locations and objects in the inner solar system, which the Committee calls the Flexible Path. (See Figure 3.5.1-1.) The goal is to take steps toward Mars, learning to live and work in free space and near planets, under the conditions humans will meet on the way to Mars. We must learn to operate in free space for hundreds of days, beyond the protective radiation belts of the Earth, before we can confidently commit to exploring Mars. Human exploration along the Flexible Path would also support science, create new industrial opportunities, and engage the public through progressively more challenging milestone accomplishments.

      On this path, sites would be visited that humans have never reached before. Astronauts would learn to service spacecraft beyond low-Earth orbit, much as crews successfully serviced the Hubble Space Telescope in low-Earth orbit. Humans could visit small bodies in space, such as near-Earth objects (asteroids and spent comets that cross the Earth's path, some of which could someday collide with the Earth - Figure 3.5.1-2) and the scientifically interesting moons of Mars, return samples, and understand their structure and composition. When humans would come close to the Moon or Mars, they could deploy probes and coordinate with or control robotic assets on the surface. They could even bring home samples from Mars that were launched from the surface by robotic spacecraft. In this way we could achieve the scientific "first" of a Mars sample return.

      These destinations require the smallest energy expenditure beyond low-Earth orbit, but are of increasing distance and duration from Earth. The missions could include a full dress-rehearsal for a Mars mission, consisting of traveling to Mars orbit and returning hundreds of days later. The essential concept is that humans would first visit points in space and rendezvous with small bodies and orbit larger ones, without initially descending into the deep gravity wells of Mars or the Moon.

      The Flexible Path is a road toward Mars, with intermediate destinations. At several points along the way, the off-ramp from the Flexible Path to a Moon exploration program could be taken. Alternatively, if new discoveries drew us to Mars, the lunar stop could be bypassed, leading directly to a Mars landing.

Why develop and fly a new huge expensive rocket, putting all your payload eggs in one basket, rather than use a greater number of smaller, cheaper, existing rockets?

      Simple engineering - the more chunks you split your payload into, the more complex the resulting assembly becomes (because now you need interfaces between the chunks), the heavier the resulting assembly becomes (because of the connectors between chunks and docking/berthing assemblies), and the greater the chance of fucking something up during building, testing, and on orbit assembly. Then there's simply math - if your rocket has a 98% chance of flight success (about average nowadays), then each launch you add to the manifest means the greater chance one will go awry.
       
      As far as expense goes, you're way off base - rocket costs scale very weakly with size, and very strongly with complexity and the number of man hours required to prep it for launch. (Which is why the Pegasus, despite it's small size and modest payload, is somewhat above the middle of the pack in $/kg to orbit.)
       
       

      The more rockets you fly, the more you have to build, and you can begin to take advantage of economies of scale and reduce the dollars per kg cost to orbit.

      That's the handwaving-and-smokescreen theory. The reality is that economies of scale in manufacturing don't begin to provide significant advantage until you're talking dozens of launches a year. Costs still really don't drop much until you tackle the problem of the standing army required to integrate, checkout, and launch the vehicle - multiple smaller launches can actually cost more in total than one big launch.
       
       

      Another advantage is that if your rocket does encounter some calamity, you don't lose your entire (much more expensive than the rocket itself) payload, but rather just a piece of it.

Well, any Mars craft could be a blank sheet design taking the lessons learned from ISS and putting them to good use. And as for delays due to the shuttle, you again make my point. If NASA designs another heavy lift vehicle, it will be the only way to get a Mars craft (or pieces thereof) into orbit. What happens if that launch system goes down to a failure? You have the exact same situation you had with the shuttle. However, if you design your Mars craft from the beginning to use existing medium lift, you'll have multiple options to get stuff into orbit (Atlas V, Delta IV, Falcon 9, Ariane, etc).

      Finally, while being able to put everything together as one big piece and launch it may simplify some aspects of the design, if we're going to really do worthwhile things in space (colonies, stations, mining) there will have to be piecemeal launches. Habitats and the like will simply need to be too big to be able to launch on a single rocket. Why not start getting really good at putting stuff together in orbit (or on the lunar surface) now?

Maybe if its bulk stuff like fuel, water or oxygen it wouldn't be so much of a problem to lose one but for those the launch is the expensive thing.

      I'm pretty sure the Apollo people thought all this out and they came up with a pretty good solution that is known to work. I wager they figured it was best to launch everything at once where possible. As prone as launches are to being aborted for technical problems and weather in Florida if you had to do many launches it could take a long and unpredictable amount of time to get everything you need in to orbit. Just hope you don't need to hit a window, to go to Mars for example.

So far they are more custom built by craftsmen than an assembly line where economy of scale would really pay off.

Most of the parts are built to very exact electronic specifications, they go through all sorts of tolerances testing, stress testing, radiation testing and so I really can't imagine them being that costly to produce exact replicas. Yes, sometimes they use highly experimental materials in these things but say for example the Mars rovers is mostly an aluminum structure with scientific equipemnt. Lithium-ion batteries are in every laptop. It's not really the materials driving up most costs.

      Where I'm guessing the big blocker is would be the modularization itself. If you build it as one "thing", you can just weld it or glue it or whatever they do together and you can do that with tons of external equipment and QA here on earth or use larger parts and don't have a assembly point at all. Also all the cables and wires and tubes that ought to go from one module to another, it all gets much harder. One thing is research robots that we can slowly send off on a space trajectory, minimal acceleration also means minimal stress. Building something like a Mars expedition craft that will assemble in orbit and reliably not have structural failure when you turn on the engines to get going is a different matter.

      The two models considered by Apollo were "Earth rendezvous" and "Lunar rendezvous". In the first model, multiple launches were used to assemble a large lunar spacecraft in Earth orbit, a true space ship, not just a coracle like the CM/LM combination. That ship would go to the Moon, land, take off and return to Earth orbit.

      Lunar rendezvous was what was selected (over von Braun's objections): a one-shot mission that would go directly to the Moon, detach a small lunar lander that would return to lunar orbit. There is no doubt this produced the lowest cost and shortest time-line for reaching the Moon for the first time. But it is equally pretty likely that we'd be a decade or two ahead in our exploration of space if we'd gone with Earth rendezvous, and at relatively trivial cost (if by "relatively" you mean "relative to what the US spends daily on killing people to ineffectually pursue poorly-thought-out foreign policy goals".)

      You couldn't be much more wrong if you tried. NASA originally proposed flying the Shuttle purely as a passenger and light cargo transport, with the Saturn V being used for the heavy lifting role. The Administration and Congress however shut the door on that plan and refused to fund resumed production of the Saturn V. NASA's 'fixation' on the Shuttle was a cause. Not an effect.

The claim that heavy-lift is truly necessary is somewhat hard for me to buy, although my suspicion is that suggesting otherwise would just be too big of a mindset change for NASA to handle. If they do have a heavy-lift system, I do hope they pick the EELV-derived heavy-lift, even if it'll be nigh-impossible politically -- congressmen have already started defensive maneuvers to try to protect the status quo. The main benefit of an EELV-derived system is that it minimizes the amount of specialized infrastructure you'd have to maintain, and since the EELV infrastructure is used for many medium-lift commercial launches you also wouldn't have to maintain a standing army of personnel specifically for the heavy-lift launcher. If it does indeed turn out that heavy-lift is unnecessary, you can simply scale back the number of heavy-lift launches; with the shuttle-derived heavy-lift, you have the pay the standing support army (the biggest part of the lifecycle cost) no matter how many launches you actually have.
