Competition to Build the Space Shuttle's Successor

Neil Halelamien writes "The competition for the prime contract to build the Crew Exploration Vehicle, the successor to the Space Shuttle, is ramping up. Currently, 11 different companies are creating preliminary designs for systems and vehicles which could be useful in implementing NASA's Vision for Space Exploration. By the end of the year, NASA will select two teams to independently develop and build a CEV design. The two teams will launch competing unmanned prototypes in 2008, at which point NASA will award a final winning contract. Aerospace giants Boeing and Northrop Grumman have formed one team. Another "all-star" team, announced a couple of days ago, is headed by Lockheed Martin. A third team in the running is underdog t/Space, a company with a free enterprise approach to space exploration, which includes notable figures from the commercial spaceflight arena, such as Burt Rutan and Gary Hudson. There is concern that a NASA budget boost to help pay for the exploration program could draw some opposition, as most other government programs are anticipating budget cuts."

If you could leave those off, with a capsule design, you could either save a whole lot of fuel and get a cheaper launch, or use the same amount of fuel and carry a much larger payload.

      BTW, the real problem with a space plane is in the aerodynamics. To avoid superheating on reentry (compared to which the space shuttle would be freezing during renetry), all leading surfaces must be big round things. That's why the shuttle looks so un-sexy compared to fighter jets. The wings leading edges cannot be sharp - no known material would survive at 50,000 C. By making the leading edges round, they lower the temperature baring within range of Carbon-Carbon - but that makes the wing have a terrible L/D ratio. In addition, instead of a nice sleek body which could be lightweight, you now have a ponderous blob which must be reinforced at every point.

      Taking aerodynamics into consideration, the best design is really like a sphere. The closer you are to a sphere, the better. Apollo took a cone and made a good aproximation of a sphere.

      I disagree. Spaceplanes may be inherently inefficient *per mission* compared to a disposable capsule design, but if maintainance costs were lower, they would easily outshine capsules with disposable rockets.

      And maintainance doesn't *need* to be high. If the shuttle had the budget for its initial design plan (a titanium frame, no solid boosters), it never would have had any of the problems that it's had that led to high maintainence costs and its 2% failure rate.

      A couple of things about your list:

      * A hugely increased heat shield: Not really hugely increased. An optimal shape for reentry is a large, slowly curved surface, and the further from that shape, the larger amount of shielding you need for a given size and density. However, the shuttle manages relatively well given its size and density compared to what an equivalent capsule would be by turning its bottom side into the direction of incoming air.

      * Hydraulic motors for flaps: Not necessarily. Hydraulics in space are problematic because of temperature regulation (in the tanks, in the cylinders, in the lines, etc). However, it is possible to use electric actuators to replace them for most, if not all, tasks. Electric actuators are increasingly being used in high force tasks.

      However, the key issue is reusability. Reusable capsules have never really come into their own - they tend to have a pretty rough landing. The more payload return you want them to be able to bring back, the rougher it is.

Utah Senators Jake Garn and Frank Moss have been active supporters of the Space Program, particularly when it benefits Utah-based industries. There is nothing wrong with this; Representatives of Congress are expected to be interested in furthering the activities of their constituents. The real cloud of suspicion hung over former Morton Thiokol employees who worked for NASA at the time of the contract award, and the head of NASA itself, Dr. James Fletcher [4]. Dr. Fletcher served as the President of the University of Utah from 1964 through 1971. His connections with the state and its industries were numerous and far reaching, but he denied that these connections had any influence on his decision to award the SRB contract to Morton Thiokol. However, many people who observed the contract award process remained unconvinced. Fletcher's inability to provide solid reasons for the selection of Morton Thiokol over Aerojet did nothing to ease the controversy surrounding the decision; his reasons were vague and referred to minor points in the advisory committee's study. NASA's refusal to discuss whether former Morton Thiokol employees had been part of the advisory committee simply fueled speculation of wrong-doing. Whether Morton Thiokol used political influence to secure the SRB contract has never been determined, but lack of clear answers caused many to conclude that the contract may have been awarded improperly[1].p/)

This is sad because China apparently understand economics better than current US leaders do. It might seem that the Apollo program was just a big expensive government program but the truth is that all the expensive science generated far more money that it spent. Science is good for the economy for it provides people with technology that lifts the economy and increases growth in the country. As complicated as going to the Moon and Mars and expensive as it seems might be, it is good for the economy. All the new technologies generate new industries which will further the economic growth. Our leaders in the US have forgotten that by limiting science funding and cancelling things like the particle accelerator in Texas. Second and most important, it is too expensive to think of old ways to get out of this planet. The best and most efficient way is to build the SPACE ELEVATOR. Fund nanotechnologies to get the cable for the elevator built.

Just the other day I was reading about a cheap nozzle throat that Lockheed patented made of a ceramic that has shown almost zero erosion - a critial step in lowering engine maintainence. They just cast it and fit it - a whole lot easier than carbon-carbon.

    Just because you see a column of flame belching out of the back of an engine doesn't mean that what's "under the hood" is at all the same. Modern engines far outperform their 1960s counterparts. Modern propellant tanks (which more and more are based on lightweight alloys, such as lithium-aluminum) also far outperform their 1960s counterparts.
