    I have had a quick search on internet and found some information about the Russian Space Shuttle, the more I look in to it appears that the Russian Space Shuttle is a more practical Shuttle compared to the American Shuttle.

    Some information found:

    Taken from http://www.buran.ru/htm/molniya.htm has the main differences of Buran and Shuttle as follows:

    The main differences between the space airplane the automatic landing of Buran from orbit onto airdrome;

    The absence of the main rocket engine on the orbital airplane. The main engine was placed onto a central block of a carrier-rocket ENERGIA which is able to launch into an orbit 120 tons of payload against 30 tons for Space Shuttle;

    The height lift-drag ratio of the space airplane is 6.5 against 5.5 for Space Shuttle;

    The space airplane Buran returned 20 tons of payloads against 15 tons for Space Shuttle orbiter from an orbit to an aerodrome;

    The cutting lay-out pattern of thermal protection tiles of Buran is optimal and longitudinal slits of tile belts are orthogonal to the flow line. Sharp angles of tiles are absent. The tile belts of the Buran fuselage and fin have an optimal position.

    Also for another comparison between USA and Russia's space shuttle go to:

    http://www.k26.com/buran/Info/info.html

    Another benefit of Buran being able to have unmanned space flights.

    One of the big benefits of the Russian Space Shuttle is the thermal protection system, unfortunately I do not know enough about it to compare it with the USA Suttle. Last I heard the USA Shuttle they must check every ceramic tile under the underbody, which cost a bucket load of money (At least the Americans have it)..

    Of course you could lighten the shuttle's load a bit by removing the big tank, but it's a long ways between 4.3 million pounds and 273,400 pounds. As someone else has pointed out, towing might be a better option.

    That said, I doubt the shuttle's airframe, especially wings, are designed to handle much more than the maximum landing weight in atmospheric flight (where the weight vector is perpindicular to the wings). I am now imagining a space shuttle blasting down a runway, and the wings take off but the fuselage stays on the ground.

      The Shuttle was proposed to be a horse of many colors because it's also very expensive to maintain and support multiple launch vehicles for multiple different roles.

      Well, sure, but of course then we ended up maintaining them anyway; we kept the Titan program going, and such, because the Shuttle couldn't meet the launch demand once the turnaround times slipped, and then after Challenger they started instituting cargo rules anyhow. And, while it isn't a launch vehicle of course, we ended up building a fabulously expensive space station-lab to do, really, the same sorts of science the shuttle science-setup is supposed to do, and that's been on the drawing boards since 1981. So sure, if the Shuttle could have been built to meet every need, but certainly at this point- and if you look at what people wanted but couldn't get funded for, even at the point of its design- there are a lot of needs it's designed to meet but isn't really making the grade on.You're quite right that it isn't appropriate to rip on the shuttle designers from today's perspective. I think they did an astounding job working from a terribly limited engineering and (especially) political base.But I think we can agree that NASA's plans in more recent times for moving beyond the shuttle have been, well, less than fruitful...

But in terms of the talk around town, I think there's a pretty fair consensus that we should look for a lightweight satellite launcher designed to fit the current commercial market, a ferry-crew-to-orbit vehicle that's as simple as possible and has no other functions, an in-space tug, and an as-friggin'-big-as-possible launcher for projects like ISS and interplanetary missions (manned or not).

      Okay, it's certainly true that with the Shuttle, as it is, NASA shouldn't be expected to be any less careful than it is. But it's also true that while the word 'reusable' does apply to the Shuttle, the extent of replacement and refurbishment required defeats much of the point of reusables in the first place. That is, the cost savings are, with the most optimistic sorts of accounting, moderate; the turnaround time is probably worse; and, with so many of the more dangerous parts being expendables or needing major referbs, the safety improvement is questionable. (And don't forget that the engineers think we're lucky we never got a catastrophe with the SSME's; we're finally going to upgrade those damned propeller blades...)

      Bear in mind that when the shuttle was proposed, it was pitched as having two-week turnarounds and cost maybe a fifth as much per flight. NASA officials sold it this way because they were looking for a way to survive in the post-Kennedy/Johnson political climate. Myself I find it hard to blame them, but it certainly should be understood that it's much too hard a vehicle to fly and that we desperately need easier ones.

      The various 'low end' transports generally cut their costs by being simpler and relying on easier technologies whenever possible. While some of the operating savings are intended to come from, say, cheaper fuels, the bulk of them have more to do with things like the number of people you need to do a launch, the redundancy and safety measures you NEED based on the reliability of your equipment, understanding how long you can expect different pieces of equipment to survive, and so on. It's an engineering design problem. A very difficult one, to be sure, but not one so far on the bleeding edge that we can't understand the problems and costs involved.And of course, we understand them rather better than we did in 1978, and we have better ways of dealing with them. (Also, not running a few billion dollars in debt on development costs for unneccessary technologies helps keep the op costs down. Venturestar, anyone?)

      As for cutting capabilities- well, the big problem with the shuttle is, that because NASA knew when they were building it that they would have no money for other programs for a long time, it had to be rather a horse of all colors. Human ferry-er, cargo ferry-er, space science lab (for eight completely different kinds of science,), in space manuevering ability, DoD was told they needed to do all their launches on the Shuttle so then they had a bunch of cargo specs to add, trying to get an impossible combination of cost and turnaround time, and all of this on technology that was barely capable of it at all... It's appropriate for the next generation of launchers to be much more specialized. We don't need to use only one to do everything. If that's 'low-end', well, sign me up...

    If NASA would just fly their missions on commercial craft instead of making "we are the world" happy faces for us on TV, there would, long ago, have been a huge competitive launch services industry. See my comment on the Kelly Act below:

    The 747 is a late generation aircraft, the Shuttle is a first generation reusable.

    The Wright Brothers flew their first aircraft in 1903. Goddard flew his first liquid rocket in 1926. The growth curves of both industries progressed quite well to mass production within 2 decades, with airplanes being mass produced in WW I and sub-orbital rockets being mass produced in WW II. The Kelly Act of 1925 got the government out of the role of supplier and into the role of customer of transport services whereas there was no analogue to the Kelly Act in rocketry until a group of us sacrificed a few years of our lives and substantial personal assets in a grassroots battle against NASA's entrenched interests circa 1990 and even then NASA didn't follow the clear intent of the law (PL101-611) when it decided to launch the ACTS on the Shuttle, among other violations of that and other programs such as launch vouchers -- which it resisted.

    The Shuttle is an N-th generation craft by a communist bureaucracy that owns the means of production -- however it is less efficient than was the Soviet space program because the Soviets didn't have a private sector to tax to bail them out of starvation, so they had to figure out that shooting corrupt bureaucrats -- or threatening them with the equivalent due to the imminent loss of a clear competition with high visibility (eg: war or race to the moon) -- is the only way to get them to stop being malfeasant.

    The 747 is a child's toy compared to the complexity of the Shuttle.

    And E=MC**2 is trivial compared to 18th century theories of the caloric.

    The 747 also requires incredible amounts of maintenance, support, and facilities, but most of this is out of the public eye.

    I didn't ignore that, since I did say: when a jumbo jet lands.

    It would be fascinating to invite over some of the engineers working in the Russian plants to see if they could streamline some of the processes used on the Shuttle, take it down from the equivalent of tuning a high performance racing car towards a regular service of a goods truck.

I'd say the Russians would be worth bring on board for their heavy engineering rather than 'gee whizz high tech' attitude towards getting these things done (I am reminded of the old tale about NASA spending all that time and money developing zero-g pens while the Russians just gave their cosmonauts 10 cent chinograph pencils and got on with the next task... ).

    Actually both numbers are a little arguable. Its possible to argue that the space shuttle costs upto $1.5 billion per launch if you include a reasonable fraction of the development costs... and NASA actually usually allows more like $300M per launch because they fold some of the pad and other overheads for the year.

    Still, the Ruskies can get to space for an order of magnitude lower than NASA can. That's part of the discomfit around the Dennis Tito- that's an unsaid part of the politics; they simply can't do things that the Russians can.

    I don't have information about whether the $4M include launch pad costs or not. Still, its hard to see how it could come anywhere near the NASA figures- I mean the entire Russian space program comes to only $120M or so...

What they told me was that in the old days when they shipped a motor to NASA they shipped an equivalent VOLUME in paperwork. It was literally a trainload of paper. They have to document who did EVERYTHING and who inspected what and any deviations from normal procedure.

    They have been sending electronic documents for about six years now but are migrating to a new system. The new documents are XML and the editor is written in Java. You would think that a bunch of instructions with checkpoints and buyoffs would be a pretty simple application but they go way beyound that. The documents are incredibly complex and powerful. Luckily the new system is going to be a lot easier to use than the old one.

So much less in fact (I couldn't find numbers) that VTOL is almost never used except for nessisary training and operational necesity. This is because in an atmosphere, we can take advantage of Bernoulli's Principal to give us lift. Remember, there are four forces of flight: thrust, drag, lift, and weight (or stall spin crash and burn as a CFI I once knew used to say). You seem to be forgetting weight and lift. We're not talking about climbing stairs vs climbing a ladder here. We're talking about lifting something up with nothing but thrust and induced lift, if you stop applying force, it's going to fall. Still don't believe me, look at some numbers. Or do a search on Google for harrier VTOL fuel consumption.

    Secondly, the X-15 (for which eight Air Force Pilots were awarded Astronauts wings as they entered the official minimum altitude for "space") was launched from under the wing of a B-52.

    I did some work for NASA at Kennedy Space Center last year. It was the coolest job I've ever had and at the same time it was a little sad. I was struck by how primitive everything is on the ground. Ground handling costs dominate the cost of space flight. Much of the ground handling is amazingly primitive. The manpower costs and time involved are astounding. Everything is done manually. Practically nothing is automated. There is much room for improvement.

    Much of this is due to union and labor issues. There is definitely an entitlement mentality there. The lab that I worked in was littered with old robots and machines developed to speed things up and reduce costs. In many cases the unions complained and had the machines removed. More efficiency = less entitlement.

    I worked with some very cool people who were passionate about their work. Many of them worked very hard. Unfortunately the majority are not as fired up. Many young and creative people work there after school, get frustrated, and leave.

    NASA is stuck in a rut that I believe there is very little chance of them escaping. Let's face it, they aren't rewarded for taking risks. They can waste millions on inefficient processes and they get a gee wizz report on CNN. Spend the same money on a failed probe and you might get your funding cut.
