    There appear to be several teams that are competing for the "Level 1" prize, so if Armadillo doesn't complete that challenge it may be taken by at least one of the other teams. Yeah, I'd expect at least a couple of teams to at least show up with some hardware capable of making the requirements for the competition.

    Considering the issues that Armadillo has gone through, I would have to say that the level 2 challenge is going to be a tough nut for any team to crack the first time through, although a couple other teams claim to have something ready for at least display for the level-2 challenge at this year's competition.

    One thing to keep in mind is that the FAA-AST is requiring contestants to submit an application for a license to fly at the competition at least 30-60 days prior to the event. This requires an "all up" test flight to be viewed by the FAA. Armadillo has completed this certification process for this year, but I'm not sure about the other teams.

    That is the wrong competition that you are noting here. Robert Cringely pulled out of the Google Lunar X-Prize.

    This one is the "Lunar Landing Challenge", which is quite a bit different. The entire competition is to take place here on the earth, and in fact is sponsored by the U.S. Federal Government through NASA, even though the prize money is now being administered by the X-Prize Foundation. It is a part of the "Centennial Challenges" that received some brief funding from congress as a result of the success of the original sub-orbital X-Prize.

    Unlike the Lunar X-Prize, the Lunar Landing Challenge is primarily to test what kind of hardware would be needed if you are to make a lunar landing, with vertical take-off and landing requirements that only use rocket powered propulsion. As a matter of fact, some of the Lunar Landing Challenge participants may be using some of their hard-won knowledge to help with the much tougher Lunar X-Prize, but it remains to be seen what will exactly happen in that case.

    I kind of agree with Robert Cringely's rationale for pulling out of the Lunar X-Prize, as his #1 complaint was in regards to getting the rules nailed down and shifting policies on things like logo requirements on the lunar lander itself (the Lunar X-Prize is expected to actually go to the Moon), and the ability to put team sponsors onto the vehicle. The article that you linked to goes into much better detail than I can go into, and there were some deep issues that brought him to pull out.

    I would have to agree that the Shuttle design (STS) should have gone through several generations of improvements over the years in terms of its basic design philosophy and cutting back the the basic assumptions of its design.

    There have been some significant changes to the Shuttle design in terms of internals, and most especially with the "glass cockpit" designs that have essentially gutted the interior of the Shuttle to be essentially a completely different spacecraft from the original Columbia flights. But none of those changes were indeed "sufficient" to really make a huge improvement in safety and reliability. Indeed some of the changes, such as the introduction of the "newer" foam used for insulation that ended up destroying the Columbia were introduced for reasons that had nothing to do with reliability but instead for other political reasons.

    The foam in particular was changed because the original insulating foam at the connectors contained CFCs that could damage "the environment" and its replacement was heavier and clumped together more. I'm curious about which caused more harm to mankind: A newer foam that released some CfCs into the atmosphere, or the remains of several astronauts and their spacecraft also blowing a whole range of compounds into the very same "ozone layer" of the atmosphere?

    When Nixon did the huge Apollo cut-backs and scaled NASA to its current level of funding (compared to the overall federal budget) there were so many electrical engineers laid off from the NASA contractors that there was a significant drop in engineering salaries all across the country.

    There were also attempts by private industry to purchase spacecraft that were "in production", most notably several individuals who wanted to buy their own private shuttle. Congress simply wouldn't even give them the time of day to even be permitted to do that, hence any such private spaceflight has to be from vehicles built completely from scratch like SpaceX is doing.

    It wasn't until very recently that even a regulatory agency (such as the FAA-AST) has even existed that could license American citizens developing their own spacecraft on their own dime.

    While I might submit to the Gemini flights as "successful" with the ratios you have given, I won't agree at all with the Mercury flights.

    There were numerous test flights of the Mercury program that resulted in decided and dramatic failures. One of the scariest was when the rocket lifted up about 1 meter and then came crashing down on the launch pad, wobbling back and forth while everybody wondered what would happen next. Or when another launch blew up just as it cleared the launch tower. There were about a dozen Mercury flights (all of them unmanned, thankfully) that were all dramatic failures, which is also why the first "passengers" on the Mercury flights weren't even astronauts but instead were monkeys.

    I think you need to dig quite a bit deeper into the statistics to come out with the figures you are using here. Certainly the astronauts watching those early test flights had cause to pause about how dangerous it was for them to go up on top of those rockets. I'll admit that not all of the early test flights were labeled as "Mercury" flights, but they were nonetheless preparatory to manned spaceflight and an attempt to get something resembling a manned spaceflight rating before anything went up that was of value.

    The cost of the fuel on a spacecraft is so minor that in most cases it is covered as a part of the "overhead" of the rocket instead of even being considered as a significant cost center for rocketry development. Something like about 1% of the cost of actually sending something up. Even if you triple the cost of kerosene, it will be something still so minor that it is hardly something to even bring up to the customer.

    The expense of rocket design has do to with the engineers and exotic metals, as well as production workers who have specialized skill like aviation-grade aluminum welding experience. Paying somebody to do that sort of work doesn't come cheap.

    Keep in mind the engineering adage that you can have things built:

    1) sooner (or faster)
    2) cheaper
    3) reliably

    Choose only two of the above options!

    A great many consumer electronics tend to select options 1 & 2. Most of the major military contracts concentrated on options 1 & 3, with the idea that cost really isn't a huge concern for a government like the USA. It is far more important that we have an ICBM that can get up *NOW* instead of sometime next year. The Apollo program especially was one that was "screw the cost, let's just get it done now!"

    SpaceX really is trying to see if they can build a rocket that may take a bit more time to develop, but can be done far cheaper and still maintain reliability. What I hope doesn't happen is that SpaceX engineers and technicians don't get under the pressure to get things done right now as well, in which case you simply end up with an expensive, delayed, and unreliable device. If you try all three approaches at once, you end up eating engineers and throwing lives away in one form or another.

    One thing to keep in mind about the payloads that have been on the current set of falcon rockets:

    All of the "customers" were well aware of the fact that these were experimental rockets on their first attempts at trying to get up. Essentially they were given a huge price break (even considering the lower advertised costs of the Falcon 1) and were essentially "throw-away" spacecraft that would otherwise not have a practical way of getting into space otherwise... at least without somebody else heavily subsidizing the cost in some other way.

    The first two, and even this last flight, were intended to be sent up with a "dummy" payload of essentially just a tank of water. With the possibility that it could reach orbit and to do so cheaply, it seems reasonable to substitute the tank of water for something else that might have a little more value.

    The upcoming scheduled "flights" of the Falcon 1 are scheduled to be carrying something of a bit more value, so I supposed that the next flight is likely going to be another cheap student project (such as was the case with last year's flight) or perhaps even the tank of water as was originally planned.

    Considering that this is a whole new rocket design from a completely blank piece of paper, it isn't that surprising that there aren't a few problems that they've uncovered when reality hits theory.

    With two huge failures at stage separation, I bet that is going to be something SpaceX is going to study real hard at over the next couple of months and come up with some more ingenious techniques to get that to happen without a flaw.

    As for what caused the rocket to stay together at a point it should have come apart (intentionally), that will be the major focus of the engineering investigation. The new Merlin-C engine (1st stage engine) did a fantastic job.
