NASA Hedges Their Bets On Return To Moon

With budget cuts in the works for everyone these days, NASA has decided to float an alternate plan for returning to the moon that is just a little bit cheaper than the current proposal. Of course, the new option would be very reminiscent of the old Apollo space capsule instead of the tricked out shuttle currently planned. "Officially, the space agency is still on track with a 4-year-old plan to spend $35 billion to build new rockets and return astronauts to the moon in several years. However, a top NASA manager is floating a cut-rate alternative that costs around $6.6 billion. This cheaper option is not as powerful as NASA's current design with its fancy new rockets, the people-carrying Ares I and cargo-lifting Ares V. But the cut-rate plan would still get to the moon."

NASA is *always* looking at *all* the options and the DIRECT people are just, simply, wrong; that's why no-one is interested in their shit. Not because there is some great big conspiracy to quash their option.. but because the mission requires a Saturn class or bigger vehicle.

You're not going to land an outpost on the Moon with a 70mt launcher, and you're definitely not going to go to Mars with that.

      Sure it does. My bet is that you can't find a single fatal accident in a manned space vehicle (in space or on the ground) where the deaths of people were the most significant loss. When you start getting into missions that are assembled with multiple launches by two or more different vehicle types, one of the things that stands out is that crews are replaceable. If a crew dies in a launch accident with one vehicle, you can switch to a second launch platform and a second crew and keep the mission going. With a single vehicle and NASA's traditional couple years of soul searching after fatal accidents, that mission would automatically be scuttled (unless you have a mission that can survive two years in space unattended until NASA resumes the launching of crews). This is why we still have an International Space Station in space. The Soyuz and Proton were able to take over from the Shuttle and keep the ISS supplied and crewed during the 2003-2005 downtime.

      http://forum.nasaspaceflight.com/index.php?topic=12379.msg349945#msg349945

      The second reason is a highly flawed NASA analysis of Direct created in October 2007 but only made public in July 2008 after its existence was revealed by Wired.com:

      http://www.nasa.gov/pdf/257003main_NASA%20Performance%20Assessment%20of%20(DIRECT%202)%20Compiled.0702.pdf

        The Rebuttal created by the Direct Team states that NASA's conclusions in the analysis are "suspect because of the flawed inputs that informed the analysis" and that "the launch vehicle that was the subject of the analysis was not the launch vehicle that was proposed by DIRECT":

      http://www.launchcomplexmodels.com/Direct/documents/DIRECT_Analysis_Rebuttal_Final_090518.pdf

      http://blogs.orlandosentinel.com/news_space_thewritestuff/2009/05/is-ares-i-adequate-obama-administration-or-order-a-new-study.html

      One can only conclude from this that there is concerted opposition to Direct that is not based on technical merit.

      As for John Shannon not being afraid to speak out, that's because he has nothing to fear. A switch to "Not-Shuttle-C" would require Congress to alter the Vision for Space Exploration, which dictates how NASA projects are funded. This would face significant opposition from NASA contractors, some of whom would stand to loose a lot of money if Constellation is canceled or significantly scaled back. Not to mention that Shannon himself said that he only has a team of about three people and that they haven't done even a basic analysis of the safety of a crewed version of Not-Shuttle-C.

      I'd like to also point out that if NASA switches to Shannon's shuttle, it would actually make it easier to switch to Direct 3.0. Assuming an upper stage is developed for Not-Shuttle-C, all the engines needed for the Jupiter rocket would have already been developed and human rated. Furthermore, the external tank tooling is also needed to build the Jupiter core, so all the necessary tooling for the Jupiter-130 will be in place. That means that switching to Jupiter rockets will be significantly easier than switching back to Ares I/V.

      The saddest part is that NASA was actually well on its way to doing things in a sane fashion, and in 2004-2005 was soliciting multiple proposals from companies for the CEV. The plan is that the top two proposals would be selected, in 2008 there would be a competitive flight test between the two vehicles, and the best vehicle would be chosen. Unfortunately, when Michael Griffin became administrator in 2005 he threw out all the proposals and instituted his personal design as the One True Way that would be faster and cheaper, even though it's actually been slower and an order of magnitude more expensive:

      http://www.astronautix.com/craftfam/cev.htm

      By the time the final CEV proposals were received, Mike Griffin had been appointed the new NASA Administrator. He saw that the CEV plan would realistically leave NASA with a half-decade gap between the retirement of the shuttle and the commencing of CEV flights. Griffin obtained White House backing to reject all of the contractor's proposals abandon the long, expensive, 'spiral' development process, and plunge ahead using existing technology and NASA's best judgment. On June 13, 2005, NASA announced the down-select of two contractors: Lockheed Martin and the team of Northrop Grumman and Boeing. However the selected contractors would only build a CEV to NASA's own design. Phase 1 was now accelerated so that a single contractor would be selected without prototyping or flight-test in 2006, so that the spacecraft could be available by 2010 as a shuttle replacement. ...

      Incredibly, NASA made the same mistake again, fifty years later. The same approach was used. First, proposals from industry were solicited. In both the Apollo and CEV cases these were imaginative, innovative, and incorporated all of the lessons of hundreds of millions of dollars of advanced research funded not just by NASA, but also by industry and the US Air Force. Superior contractor designs using the Soyuz-type separate orbital module or a winged spaceplane approach were made in both cases. In both cases the contractors were thanked, and NASA then proceeded with its own in-house government design. This was then suitably tweaked until it will passed the Congressional pork test.

      Just look at the Explorations Systems Architecture Study for an example of NASA looking at problems in a blinkered and myopic way. Recently, they finally released most of the appendices that described the reasoning and data that they used for justifying the Ares I. There were numerous biases. For example, the ULA people couldn't correct NASA's mistakes about the Delta IV Heavy and Atlas V Heavy vehicles. Assumptions were made about those two vehicles' performance (namely upper stage performance, IIRC) that fell well short of existing counterparts that the ULA launches today. Bogus safety numbers were used to inflate the Ares I loss of crew and loss of mission number (namely, that the failure rate of the solid rocket motor is something like 1 in 3700, which doesn't mesh with what it historically is). They ignored thrust oscillation which is a well known property of solid rocket motors. And the Ares I wouldn't even qualify, if it had to meet the same requirements as the Delta IV Heavy and Atlas V Heavy. As I dimly recall, either max acceleration or max Q (the point of maximum force from air resistance) requirements had to be relaxed significantly in order to let in any vehicle which used a solid rocket motor as first stage.

      And to top this all, speculation has it that Shannon introduced the Shuttle C study merely to divide support for the DIRECT option (another Shuttle derived rival to the Ares I/V platforms which is a bit less Shuttle derived than the Shuttle C option). There's the possibility that NASA still is going on in its blinkered and myopic way.

But it's worth keeping in mind that in the case of the Ares I/V mess, NASA decided the objectives to be just out of reach of the Delta IV Heavy, they stacked the study (whether it was intentional or not remains unknown) in favor of the Ares I, and they decided the Ares I was safer and would deliver the overall objectives even though no such vehicle will come about till some time in 2015 (when the Ares 1-Y finally launches).

There are also limitations on mass, which have required additional engineering on the Orion and a cut in the number of people carried to LEO. A single booster, while it generates a lot of thrust, has insufficient capability to carry a heavy manned vehicle to LEO. I'm aware that the current Ares V design requires the booster; and, that cutting Ares 1 development moves some of the booster development cost to Ares V. For what it's worth, this applies to your previous suggestion to use SpaceX COTS capability as well. I'm suggesting that using the booster in the Ares I configuration to launch people to LEO is a poor plan.

    2. During the lunar program, there were supposed to be 20 Apollos. Only 14 flew. The reason was that, once Armstrong landed, the public lost interest. When that happened, the political currency of the program evaporated.

    3. Humans are huge consumers of resources. Flying those resources to the moon is very expensive.

    The concept should revolve around devising robots to establish a human habitable base. This should be the way that we explore Mars. If we can do this on the moon, then we will learn something for Mars exploration. At that time, and only at that time should we consider sending astronauts to the moon (once the station is built for them).

  30. No one's going to the moon by Simonetta · · Score: 1

    Every time the NASA topic comes up on Slashdot, there are several hundred technical comments about the nature of the rockets and environment of space. And every time the subject appears it is necessary for someone to point out the reality of the situation.

        The reality is that the USA is broke. Not only broke but trillions of dollars in debt. Not just trillions in debt but facing unprecedented challenges in energy resource depletion, over-population, financial collapse of the world banking institutions, climate change, permanent governmental grid-lock, and near-universal hostility from the other countries with growing economies.

        Priorities are going to be set. The things that were important in the 1960s are not important any more. What this means is that there is going to be a lot of talk about man's destiny to travel to the moon and some superficial funding. But there is going to be no real effort made to return to the moon. The programs are going to be cut year after year.

        The reason is obvious. There are real problems on the earth. They can't be ignored. There are no real solutions to these problems on the moon. Actually there is nothing on the moon. Going there is essentially a symbolic gesture:it's an act of engineering masturbation. Back when the USA was rich and powerful in the 1960s, these kind of symbolic projects could be supported and funded.

        Those days are gone. We live in a different era. Accept it; because it's reality. And as engineers, reality is the most important consideration.

        Man will return to the moon, it's true. But it won't happen in our lifetimes. It will happen in two or three hundred years from now. Learn to think long term.

        The same thing applies to Mars exploration. You've seen the photos from the robot landers. It's a desert. No plants, no water, no nothing, just rocks and dust. Given the problems of the USA and Earth at the present time, there is no moral, physical, military, or political justification for spending hundreds of billions of dollars on space projects of this magnitude.

        Please understand, it is in your best interest as technocrats and engineers to not support such projects of no social import such as manned interplanetary travel. If billions are spent on projects of this nature, and the economy continues to collapse, then you will be presented to the angry public as a scapegoat by the politicians. Lost your 401K, no health care for your children, living in your car because your underwater home foreclosed? The politicians will claim that it is all the fault of the engineers who pissed away billions of dollars for Mars/Moon landings.

        Believe me, you don't want to be in the position where the massive social unrest of the 2020s is going to be blamed on the projects like moon landings that you publicly supported in 2009.

        Please consider the political reality of this situation. Space engineers are being set up like fools to take the blame for situations that they had nothing to with creating.

  31. The problem with that viewpoint, Simonetta by Xaedalus · · Score: 1

    Is that once you start going down that road, it is enormously difficult, if not impossible to come back to exploration again. I give you the Ming Dynasty as an example. Prior to the first Ming Emperor, China ruled the seas with its ships the size of our WWII aircraft carriers. They explored beyond the limits of the known world and kept going (granted, they did it because it was very profitable - I will readily concede that point). It was also a point of national pride. Then the first Ming Emperor came to the throne, a xenophobic agoraphobe who turned his entire nation inward to 'solve' the problem of foreign contamination. And it took China 1500 years to recover from that. I could come up with more examples offhand but I'm going to summarize: The problems you have listed are ENDEMIC to humanity. They will NEVER be solved, not in my lifetime, not in anyone's lifetime. There is no hope of solving them because if we start down that path, all we do is end up chasing our own tail. Humanity's progress and solutions have only occured when we pushed beyond our familiar boundaries into the unknown. So to make any real and effective attempt at solving the problems you named (while embracing the paradox that we will never be able to solve them completely), we HAVE to go to the moon, and we have to go to Mars. If we give up our Explorer spirit, we give up everything else and fall into a cycle of stagnation from which there is little hope of recovery.

    Thank you for your interesting response. But you are missing the entire point of my post.

        The point is that the global problems are unprecedented and very real. They can only be solved and dealt with by focused application of resources directly on the problems themselves. Exploration is a general approach to problem solving. Exploration itself doesn't solve problems. These 21st century problems that we face must be solved or humanity will either die or enter another period of dark age that will last hundreds of years.

        The absolute last thing that we need to do to address 21st century problems is go to the moon.

        Politicians are not equiped to solve engineering problems. They are good at directing public anger away from the institutions and corporations that fund their political campaigns. If the current problems continue to grow, and there is no reason to believe that they won't get worse, then the politicians will need an easy target to redirect public anger away from institutions and corporations. The moon/Mars exploration crowd is an easy target to direct public anger towards. The space engineers have no political consciousness. They are essentially naive fools when presented with situations outside of their technical specialities.

        The fact that they continue to insist that space exploration is absolutely critical to mankind's survival only confirms this. Humans have lived on earth for 50,000 years without having the means to go into space: space travel is not essential to human survival. Don't present metaphorical horseshit in public as scientific fact: it doesn't reflect kindly on your reputation or profession.

        The Chinese did not have aircraft carrier sized ships 1500 years ago. They had large treasure ships that explored the east African coast and traded with India 600 years ago. There is some evidence that they reached the Americas in 1421/1423 as presented in Garvin Mendes' books on pre-Columbian explorations. These ships were nowhere as large as a modern aircraft carrier.
    They explored lands that was basically the same as those that they came from. They didn't go into places that had no land, no water, no air, and no hope of finding any resources or trade that would justify the cost of their explorations. The Chinese empire was rich at that time. They were not trillions of dollars in debt and dependent upon foreign capital to support their government expenses. Their situation had nothing in common with our current situation.

    I appreciate the alternate design as a neat hack. But I'm becoming frustrated with NASA's goal-only orientation. Just getting to the moon does nothing to promote or assist other programs. The stepping stone approach would make it possible achieve the same goal plus many more. It'd take longer and cost more at first, but in the end far more could be achieved with less money. Instead of getting to the moon in 5 years, spend that time and money turning ISS into a construction and fueling facility. In 10 years we could be sending as many vehicles to the moon each year as they'd plan to send on any of their presently considered designs in total. In 20 we could be sending the same amount of traffic to Mars. And in 40 years, rather than celebrating "One Small Step" with plans so have another small step and little else to follow, we could be sending mail on supply rockets to the colonies on the moon and Mars, and building Clarke's Jupiter (or Saturn in you read the book instead) mission vehicle Discovery. And during all this, building more orbital stepping stones, which would require long term or even permanent residents to carry out the work, and we'd be on track for O'Neil's vision of orbital habitats. So some are orbiting Boeing or Lockheed factories. At least they'd be there.

  40. Solid Rocket Booster agenda of NASA by twosat · · Score: 1

    The main reason why NASA is so eager to use the Sold Rocket Boosters (SRB) of the shuttle is that the military uses a lot of solid rocket engines in their missiles. The manufacturers of the solid rocket engines would lose a lot of business when the shuttles are retired, reducing their economies of scale for the rest of their products. The SRBs cause a lot of stress on the shuttle because they accelerate at full power, vibrate a lot, and cause heavy air resistance at low altitudes. On the first flight of the shuttle, the SRBs thrust over-stressed the shuttle's tail and the hydraulic system of some control surfaces. The pilots have said that had they known what had happened they would not have had confidence in the shuttle to safely return and would have ejected at low level. Columbia could easily have been destroyed on the first flight!

Thing is, we don't have to impress the russians anymore and show how big anICBM launcher we can build, so the missile paradigm is really not necessary. Besides, it cuts down on the sound generated as the craft goes through space, and doesn't annoy the aliens. Shuttle has exceeded its original operational lifetime by 17 years. It was supposed to be retired in 1990 after flying through the 1980's to the "Skylab" based Space Station. Trouble is congress, even with money grabbing power like Ted "Keg" Kennedy, can't reach into space and embezzle, so the money stays on earth. It is easier to promote graft and corruption when you can keep your grubby hands on it instead of watching it fly out of reach. We should have had a moon colony 20 years ago. a space station years earlier. We can't even put up a two bit space station ourselves. We have to rely on the French, russians, and the EU. Let alone the type envisioned by people like Sir Arthur C. Clarke. The key to space exploration is establishment of an orbital platform at one of the La Grange Points between Earth and Moon, and launching from there with much less fuel requirements. Also provides a very stable and long life orbit with very little chance of decay. Good jump off point for Mars as well as you are not fighting Earth's gravity as much. Use the remaining shuttle launch vehicles (tanks and boosters) to heavy lift materials into orbit, and then assemble in orbit and ferry to the LaGrange point of choice.

As one of the children of the 60's and 70's, the bright dream of a future of space travel has turned into a very dim nightmare of R/C cars on Mars, and the inability to even return to the Moon.
