House Outlaws Obama's NASA Intervention

TopSpin writes "NASA's Constellation Program and Ares rockets appear to have strong support in Congress. An appropriations bill passed by the House includes language that bars 'any efforts by NASA to cancel or change the current Constellation program without first seeking approval of Congress.' The Administration's appointed NASA leadership is being publicly hostile towards its traditional aerospace affiliations. As Charles Bolden put it to industry execs, 'We are going to be fighting and fussing over the coming year,' and 'Some of you are not going to like me because we are not going to do the same kind of things we've always done.'"

      and releases a similar amount of energy per unit mass?

      Ah, but on this part, you're wrong. Hydrogen has more than 2 times the density of oil-based fuels, meaning that it takes up roughly 4-5 times as much volume per unit of energy. In which case, if we go with my original estimates, the space shuttle carries about twice as much energy as a jetliner.

      Really, I was being generous with the estimates - very few airliners actually carry 200,000 liters of fuel, and even those that do certainly don't burn through every single drop (it tends to make the landings rather bumpy). So I guess the energy expenditure to get the shuttle into orbit is the same as, say, 3 transcontinental flights. Which really isn't as bad as I thought - and thanks for the info about hydrogen density - but still isn't nearly as good as you originally claimed.

      As it turns out, I based the cost of the rocket on cost of fuel consumed per kilogram of payload. That naturally takes into account the inefficiency of having to bring your own oxidizer with you (which increases overall propellant consumption considerably) as well as any other such inefficiencies that consume more propellant.

      Yep, I've got no problem with that part of your comment.

Me and my luggage together probably weigh 120kg+, and last time I checked I wasn't paying between between $12,000 and $36,000 to fly anywhere on the earth.

      If I recall correctly, Jerry Pournelle estimated that the energy requirement to get mass into orbit is similar to the energy requirement to fly the mass around the world twice. But as you noted, the shuttle takes a whole lot of fuel. What's up with that?

      First, let me rant for a moment. The major cost of the space shuttle is not in fact fuel, but the cost of all the man-hours of service required. A 747 can land, unload passengers and luggage, load fuel, more passengers and more luggage, and take off again. A 747 spends much more time flying than being maintained. The shuttle, on the other hand, requires a standing army of 10,000 people to service it, with months of labor-intensive work to prep for the next flight. Henry Spencer observed that it takes over a million signatures to launch a shuttle flight: as in, run down the checklist, doing the observations/maintenance/whatever, then sign that the checklist is done, times a million.

      Okay, back to fuel costs. Let's compare the biggest version of the 747 and the shuttle:

      http://en.wikipedia.org/wiki/Boeing_747-8

      http://en.wikipedia.org/wiki/Space_Shuttle

      Empty and unfueled, the 747-8 is 214,500 kg. It can carry somewhere around 240,000 liters of fuel (the only exact number in the article is for a passenger version of the 747). The maximum liftoff weight is 442,000 kg. The maximum zero-fuel weight is given as 291,000 kg, so the maximum cargo weight possible is 76,500 kg. If you load max cargo and fuel it up to just under maximum liftoff weight (let's say 185,000 liters of fuel) you have a payload mass fraction of 76,500 kg / (442,000 - 76,500) kg == 0.209 or 20.9 percent.

      The gross liftoff weight of the shuttle is given as 2,000,000 kg (obviously a rounded-off number). The payload to orbit is 25,060 kg. The payload mass fraction is 25,060 kg / (2,000,000 - 25,060) kg == 0.0127 or 1.27 percent.

      In short, the shuttle is freaking huge and freaking heavy, which is why it needs a freaking giant load of fuel to get to orbit and back. You need the fuel to carry the payload, plus the fuel to carry all the other stuff, plus the fuel to carry the fuel off the ground. (And the fuel to carry the fuel to carry the fuel... it does end up as a finite amount of fuel, but I guess you need calculus to calculate how much it would be.)

      You could win big if you had a small, one-piece vehicle that could carry a small payload (say, 1,000 kg) into orbit and not need man-centuries of labor to overhaul it between flights. It's important for cheap operations that pieces not fall off during flight, needing to be replaced (or recovered and refurbished). Such a vehicle could theoretically routinely fly into orbit with fuel costs dominating, just as fuel costs dominate aircraft flights. This is the "space pickup truck" often mentioned in space discussions.

      Also, for supplies like dried food that can handle horrible accelerations, theoretically you could build a super-cannon that would launch a capsule into orbit. It turns out that the capsule would need to have onboard engines that would fire and alter the trajectory, causing the capsule to stay in orbit instead of returning to the ground; there is no trajactory at which you can fire an inert payload such that it stays in orbit and doesn't return to hit the ground. But if you could make such a cannon and capsule, that ought to be the cheapest way to use fuel to put things into orbit. (I mean cheapest operationally; I'm not estimating R&D costs, or the costs of building the cannon. And if you could build a "space elevator" that should be the cheapest way to put things into orbit, short of new physics such as teleportation.)

Neither Barack Hussein Obama nor John McCain is Hispanic or Asian. So, Hispanics and Asian-Americans used only non-racial criteria in selecting a candidate and, hence, serve as the reference by which we detect a racist voting pattern. Only about 65% of Hispanics and Asian-Americans supported Obama. In other words, a maximum of 65% support by any ethnic or racial group for either McCain or Obama is not racist and, hence, is acceptable. (A maximum of 65% for McCain is okay. So, European-American support at 55% for McCain is well below this threshold and, hence, is not racist.)

      ... in light of the national budget, I can hardly see how everyone on here can say that Ares is a waste. NASA gets roughly 18 billion of a budget of 3 TRILLION dollars. That is a fraction of a percent. For technological advancement in basic sciences, it is hard to get a better bang for the buck.

      We've figured out a lot of ways to get good science "bang" for the buck. Ares isn't one of those things. First, it does no science. That's not the purpose of Ares. Second, there's little reason to expect that we'll get anything other than a 20-25 ton launch vehicle out of Ares. The heavy lift vehicle, Ares 5 is just a vapid promise right now. There's no concrete work being done on it aside from the commonalities that it has with Ares 1. In particular, given the time (2018 or beyond) I consider it likely that Ares 5 will be canceled.

      Third, Ares competes directly with commercial launch vehicles. My view is that we should be stoking commercial endeavors, if for no other reason, than because they are self-funding activities in space that on their own justify the US's decades of massive spending on space exploration, science, etc. Instead, NASA proposed to go, yet again, with its own design. I feel the difference between NASA using Ares and using the EELVs is decades of progress in space. Encouraging private investment in space is in my view one of the most important things NASA ever does.

      Finally, Ares has consistently underperformed in numerous ways and NASA has grossly exaggerated both the performance and safety of the vehicle. It is in fact creating risk in the rest of space exploration. Even if the overblown estimates of Ares's safety were correct, the choice of the vehicle forces mass cutting in the lunar program which IMHO increases the overall mission risk more than if a more capable but riskier vehicle were used.

      While it's always possible for a project to get canceled (in both the public and private sectors), I really doubt it's probable for the Ares V. First, while they haven't started construction, the Ares V is really an extrapolation from the existing Shuttle stack. The main differences are the liquid rocket engines are on the bottom of the liquid fuel tank (instead of bolted on the side via the Orbiter) and the payload is riding on the top (again versus the Orbiter being on the side in the current stack). All the other differences, e.g. more liquid fuel engines and SRBs, come about because of the increase in scale. So unlike the Ares I, the Ares V can directly apply the majority of the experience with currently existing hardware.

      If by "Ares" you mean "Ares I", I can agree with you to a large extent. While there aren't currently any human-rated EELVs at this moment, there are some existing models that could be modified to launch people safely, arguably using less time and money than would take to finish developing the "Ares I". However, unless and until an extraterrestrial industrial infrastructure is developed we will need heavy lifters to do more than we are currently doing in space exploration/exploitation. At present there really aren't any existing heavy lift launch vehicles available from the private sector; so NASA will have to commission the design of one, be it Ares V or some other design.

    Chem rockets can't achieve the efficiency of jet engines because they carry their own fuel and oxidizer. Jets only carry fuel and thus need to propel less weight. Rockets also must generate enough thrust to support the entire vehicle weight. Jets normally fly at thrust-to-weight ratios below one, by having wings that rest on the surrounding medium (air, lift). Rockets must also propel their payloads under these conditions to ~330,000 ft. Commercial airliners reach cruising altitude at 35-40,000 ft. The climb gulps fuel, but the following cruise sips it; rockets are climbing the entire time. This is all scraped from undergrad propulsion, but I think it's right.

    One solution is to combine propulsion methods, to use airbreathing propulsion for atmospheric flight and rockets beyond. This could be either a combined-cycle engine (turbine with a rocket in the spindle), or something like SpaceShipOne/White Knight, where a jet-powered platform brings a rocket-ship to altitude. Chemical rocket costs aren't just limited by rocket makers trying to maximize profits on limited launches. They're inherently less efficient than airbreathing propulsion, but aren't limited by the atmosphere.

      You are confusing cost effectiveness with efficiency. Thermally the Space Shuttle Main Engines are about as efficient as you are going to get, so the engines themselves are not the problem. Yes they have to carry both oxidizer and fuel, however the application is different.

      Your first solution implies that you need to carry two engine systems, two fuel delivery systems, etc... which may negate any oxidizer weight savings.

      Your second solution has size limits (how big a vehicle can be safely sent into orbit using this mechanism.

      Another issue related to cost is that if the vehicle is completely reusable (and using hydrogen as a fuel), then your vehicle will have to be much heavier as the hydrogen tankage and supply system will have to be built to withstand landing and reuse.

      Another cost issue is with the limited number of launches. A lot of NASA's costs are related to supporting the program itself, and not specifically launches. Those costs don't go up when the number of flights increase (they don't go down when you lower flights either). If NASA can only justify 3 Ares I flights per year as an example, then those fixed costs are spread over the 3 launches, making the cost astronomical.

    Yeah, and still only 9 judges for 330,000,000 people and they never have time to hear many important cases and decide those cases as narrowly as possible? FAIL.

    Actually, that bit actually makes sense. The courts of appeals (and of course the district courts) are supposed to get it right the first time.

    What else can you do, have 14 "supreme courts"? And what happens when various ones of those issue conflicting rulings? Now do we have a "super-supreme" court? At best we could have an extra layer, but that makes things even more astronomically expensive for anybody who actually has a case that needs to go through all the appeals.

    One thing that would help is if the court could issue general guidances to the lower courts before a case reaches it. Those should be kept simple, and wouldn't have the full weight of actual decisions. However, if they can see that half the appeals courts are doing it one way and half are doing it another, they could just say - do it like these guys are doing it.

    The problem with the current system is that in order to even get an argument before the court you need to be involved in a suit or charged with a crime. That is a huge risk to get yourself into.

    Suppose congress passes some unconstitutional law that says I can't do X, but I'd rather do X anyway. Suppose I even think that the supreme court will rule that X is unconstitutional. If I do X and get caught I'll space time in prison, I'll spend money on bail, I'll spend a fortune on lawyers, and I'll spend half of my life for a few years in courtrooms. As soon as the first court rules against me I might be filing appeals from prison, or I'll have paid fines that I don't get interest back on if the ruling is reversed. And, there is a risk that the court will uphold my sentence and I'll get nothing back. So, everybody just keeps their heads down and follows the unconstitutional law.

    Then think about how much work goes into creating the perfect "test case" that some special interest wants to go to the court, so that a ruling comes out that is most skewed in their direction. Why not just have the court issue guidances in the absence of a specific case, and then they can still hear appeals if they need to refine things?
