Ares 1-X Ready On Pad, Launch Set For 1200 GMT

DynaSoar writes "NASA's new Ares I-X rocket is undergoing final preparations for its planned launch test Tuesday, October 27. Launch time is scheduled for 8 AM EDT (1200 GMT). As of noon Monday it appeared that there was a 60% chance of showers and/or high altitude clouds interfering. However, the launch has a an eight hour window of opportunity through 2000 GMT, and would require only 10 minutes of clear skies within that time to fly. Of interest to engineering types, both those who favor the new vehicle's design and its critics, will be to see whether the predicted linear 'pogo stick' oscillation will occur, and whether the dampening design built into it prevents damaging and possibly destructive shaking. Extensive coverage is being presented by Space.com; for NASA TV streaming video, schedules and downlink information, visit nasa.gov/ntv." Update 15:37 GMT by timothy: The weather did not cooperate; today's planned launch has been scrubbed.

      NASA test flight delayed, bad weather still looms

      CAPE CANAVERAL, Fla. - NASA's newest rocket is on the verge of blasting off on a test flight, but minor problems are causing last-minute delays.

      The Ares I-X rocket is set to lift off Tuesday morning. But forecasters are monitoring upper-level winds and clouds that could delay the experimental flight. It's already 1 1/2 hours late because of extra time needed for the countdown and minor communication system trouble.

      This is the first step in NASA's effort to return astronauts to the moon.

      The flight will last two minutes. Parachutes will drop the first-stage booster into the Atlantic for recovery. The upper portion of the rocket -- all fake parts -- will fall uncontrolled into the ocean.

      Actually, that is *not* true in general. It was true for the original Atlas, and is true for the Centaur high-energy upper stage, but most other modern launchers avoid balloon tanks. Most modern designs are very fragile, but self-supporting when unpressurized. That doesn't mean you can hoist them any way you please, but it's still a vast improvement in ease of handling. One of the requirements on the Shuttle External Tank design was that it not be a balloon tank. It was later discovered (to much embarrassment and annoyance) that the ET is self-supporting when empty or full, but that there is a partially-full intermediate range where it isn't, so it has to be filled while pressurized.

      Some smaller launchers are assembled horizontally; in particular, SpaceX's Falcon I and Falcon 9 are. They're still fairly fragile, but they're closer to the Russian design approach in a variety of ways.

      However, all of the options presented push for a heavy lift capability. Other options include
      - 'Ares V Lite': a lower-performance version of Ares V that would be human rated and could potentially reduce development costs primarily by eliminating the need for Ares 1
      - Shuttle-derived: Either a sidemount cargo vehicle (probably requiring something like an Ares 1 for crew launch), or a top-mount shuttle derived design like Jupiter. These would be less capable than Ares V, but still powerful and potentially cheaper -- you could achieve a lunar mission with 2 or 3 launches.
      - EELVs: Creating larger Evolved Expendable Launch Vehicles from the Delta or Atlas family. These would be the least capable. These are also the biggest question mark because cost savings would come in a large part from a restructuring of rocket development to a DoD style model, where contractors are given requirements, not designs.

      The problem is that with the Ares I, NASA's pretty much has a case study in how *not* to reuse existing launch components. Mike Griffin's conceptual design of using a single giant solid rocket as the first stage of a manned vehicle had some pretty fundamental flaws, and the only reason it's NASA's current focus is because he shoved it down NASA's throat when he was administrator. On top of that, the Ares I design has moved from the 4-segment SRB used on the shuttle to a 5-segment solid rocket booster (which will have entirely different flight and vibration properties) and different liquid engines for the second stage, meaning there essentially aren't even any reused components anymore. Finally, the projected cost per launch is $1-$2 billion, for a vehicle with even less capability than the Space Shuttle at a considerably higher cost -- what was the advantage of reusing components supposed to be again?

      Although I have my own qualms with them, a far more reasonable approach is that taken by DIRECT or NASA's sort-of new sidemount design, which actually *would* take advantage of existing components and not introduce huge fundamental design problems like the Ares I.

So they built it with spherical tanks like a Goddard rocket, giving it a lousy mass to thrust ratio. Then the Soviets compounded the problem by only testing selected engines out of each production batch, instead of test-firing all of the engines. Lastly, their design didn't cope with engine failure at all well, which is a problem when your testing regimen guarantees engine failure.

      The Falcon 9, on the other hand, uses a thoroughly modern design. Its engines are more reliable than the N-1's, and have been test-fired as a group successfully. Plus, it shares many components with the now-proven Falcon 1a design.

Pretty much the only failure modes SRBs have are catastrophic explosions, and since you can't shut them off like you can with liquid rockets it makes it rather difficult to launch-escape if something goes wrong. It's also considerably more difficult to handle for the ground personnel, as summarized well in this blog post by "Chair Force Engineer":

      http://chairforceengineer.blogspot.com/2009/10/worlds-largest-stick-of-dynamite.html

      Just when it seemed like the history books had been closed on the Challenger disaster, I came across a review of Truth, Lies & O-Rings, an interesting look at the faulty decision-making leading up to launch. (hat tip to Clark Lindsey's Hobbyspace.) The reviewer makes an interesting point about the dangers inherent in ground handling of solid rockets. Many of the inherent disadvantages of SRBs have been long-discussed, such as the inability to shut them down during abort situations. But handling and storing the motors carries all the potential dangers of riding on them. For that reason, SRB stacking operations are classified as "hazardous operations," and all non-essential personnel are banned from the Vehicle Assembly Building. The procedure is similar for stacking the stages of other solid-fuel launch vehicles. In spite of all the precautions and built-in safety mechanisms, the potential always exists for a catastrophic solid-fuel detonation, as occurred with Brazil's orbital launch vehicle.

      While I tend to think that the risk is overstated (the industry has been dealing with large solid rockets since the 1940's,) it can never be entirely eliminated. For this reason, Jeff Bell predicted that the SRB would be deleted from the shuttle-derived launch vehicles under development by NASA. Many "space boosters" are dismissive of Jeff Bell, viewing him as a cynic whose arguments aren't worth the paper they're written on. I'll concede that his predictions often come with fatal flaws, but he does make a lot of solid arguments and presents plenty of pertinent facts. In the case of the aforementioned prediction, Jeff Bell's fatal flaw is assuming that NASA would choose a safe, clean-sheet launcher design over one that protects the shuttle's entrenched workforce and contractors.

      The ground-handling of large solid rockets (and even the individual segments) was an issue that should have been re-examined when Ares I was designed to be "safe, simple and soon." While NASA personnel have done an admirable job in handling the SRB's up to this point, it's sobering to know that just one mistake could cost a lot of lives and pull the plug on the nation's manned space program. The Ares 5-segment SRB will be the world's largest stick of dynamite, and that risk should never be lost on anybody who works in the space business.

      likely hundreds of solar systems in our immediate vicinity at our disposal

      Not really. The nearest star to ours is about 2.5 light years away. Even assuming we could have a quantum leap in technology that allows us to get to HALF the speed of light, that's a 10 year round trip. To make any sort of mining/resource gathering/anything happen would require a round trip of ten years. Further assuming that you wouldn't be able to just touch down and start the trip back, you would need to add more time before the return trip/shuttle. Extrapolating that, if your return trip is that amazingly long, you better have either an amazingly valuable cargo (unlikely) or you would need to return with enough of the stuff in a trip to make over ten years of investment pay dividends.

      I think a much more likely scenario for extra solar travel would be likely not to get out there, make some cash and return, but make a one way trip and seed a colony of sorts. I am not saying I don't think it's worth it. I really do think that general scientific research and space program's should be getting a much bigger slice of the pie compared to what they get, after all if there is so much money being thrown around right now, why should only the people who were BAD at their business get the "general fix this economy funds" thrown their way.

      I don't think that cutting welfare is the best option for a country. I do however think that if a tenth of the money that the US spends on the military was spent instead on NPOs in other countries, even the very ones that you are at war with right now, there wouldn't be a need to be at war with them. Each day at war costs around $720 million dollars (Source Washington Post) and if instead of spending that much money to effectively do nothing (sorry, it's been such a miserable failure) the same money was spent on building hospitals, schools and general infrastructure in the same areas, there would not be such a high level of hostility and resentment from that region to the US. You don't make someone like you by invading their country, throwing out their leaders (no matter how they got there) and then telling people how to live. You make them like you by doing nice things for them. How can someone hate you when you built the school they went to, donated the hospital their family goes to and fixed their water and electricity supply from something shoddy and broken to functioning?

      So, cut the war budget, be a little altruistic to other nations and do your "shock and awe" through sending amazing pictures to the world of what you did. Make a moon colony. Send a space ship to Mars. Send some real probes in hordes to every planet in the system. That will once again give people some awe of your country.

      This won't make you directly rich by bringing back intergalactic booty, but it might just make you richer in ways you didn't expect and through other money you won't have to spend.

    • The Ares I-X has roughly the same shape (but different internal components) compared to NASA's planned medium-lift Ares I, which is scheduled to be completed after 2017 with an estimated cost of $1-$2 billion per launch. A lot of people have been calling this a flight test of the Ares I, but considering how drastically different the Ares I would be in flight, it's really quite a stretch. If anything, it's more similar to a full-size wind tunnel test.
    • Even though the fate of the Ares I itself (and the overall future direction of NASA spaceflight) is uncertain, the >700 sensors on the Ares I-X should provide data useful for validating computer models used by NASA."
    • For all its faults, it's still worth noting that this is somewhat of an accomplishment for NASA, as its the first new launch vehicle design they've attempted to launch in 30 years, after a long string of failed designs (X-30, X-33, X-34, National Launch System, Space Launch Initiative, Orbital Space Plane). Actually, now that I think about it, the DC-X successfully launched, although I suppose that was constructed by McDonnell Douglas for the DOD before it was transferred to (and canceled by) NASA. Of course, one could still ask why NASA is trying to internally design a new vehicle when the private sector has a much better track record over the past 30 years of bringing new launch vehicle designs into service, but I imagine it's still been a learning experience for NASA.
