US Air Force Launches Secret Flying Twinkie 234

Spectrummag writes "One of the most secretive US Air Force spaceflights in decades, launched this month, is keeping aficionados guessing as to the nature of the secret. The 6000-kilogram, 8-meter X-37B, nicknamed the flying Twinkie because of its stubby-winged shape, is supposed to orbit Earth for several weeks, maneuver in orbit, then glide home. What's it for? Space expert James Oberg tracks the possibilities."

    A scaled up version of this could replace capabilities that the shuttle provided to the military.

    Sure they launch sats on rockets now, but they can't do any of the maintenance with a rocket. Also is folks listened to the MIT lectures on building the shuttle, they mentioned that the engines in the shuttle wouldn't have to be torn down and rebuilt between flights if the electronics were built onto the engine such the engines could be tested without removing them.

    I'm sure there are other what if style improvements that the shuttle built from blueprints could benefit from in the age of CAD that would aid in the rapid turnaround of any new vehicle designed with the Twinkie's test data.

      That's relevant to the things that electronics can test for. (A very small subset of the things that are tested/inspected on and SSME.) Not to mention that if such things were truly practical (electronics substituting for inspection and/or teardown), commercial aviation would be using it for jet engines.
       
      Not to mention that they haven't removed the engines after every flight for over fifteen years, and haven't rebuilt them every time they're removed for over a decade.
       

      I'm sure there are other what if style improvements that the shuttle built from blueprints could benefit from in the age of CAD that would aid in the rapid turnaround of any new vehicle designed with the Twinkie's test data.

      This vehicle's (single flight) test data is roughly meaningless compared to the thirty years of flight experience for the Shuttle itself. Seriously, the Shuttle's problems don't stem from lack of CAD. CAD is just a fancy version of Microsoft Paint - you still need the engineering information behind the design. Without that information it doesn't matter if you use chisels on stone tablets or the latest engineering workstation.
       
      There lies the key problem with the Shuttle, lack of funding, lack of basic technology research, lack of engineering development, and a healthy helping of excess ambition on the part of NASA and successive Congresses and Administrations. The Shuttle went wrong when those three collectively decided not to expand on the groundwork laid by the X-15 and the various lifting body projects in favor of Buck Rogers stunts.

    So the article speculates that this is a testbed for on-orbit threat detection systems, which given the number of countries getting into the space gig seems like a reasonable thing to be working on.

    So here's why bit I don't get: Why build it into a space plane rather than a regular satellite? Seems to me that you're adding an order of magnitude to the complexity of the mission -- do they really need the sensors back that badly, or is this maybe for something else?

        I'd actually think that something like this would be ideal to TAKE OUT a satellite, or a satellite interceptor.

        A polar orbit means that its relative velocity would be large compared to any less inclined orbit.

        Ability to launch and return in a single polar orbit means that it would be hard to shoot down - it would have to fly right over an enemy launch site to do so since they wouldn't spot it until it was entering their airspace and there would be no time to vector an interception from elsewhere. You only have a few minutes to launch even if you happen to have an ASAT missile right on its flight path (which obviously the US would avoid anyway when they put it into orbit).

        So, the USAF identifies a bunch of satellites they want to shoot down, then they put this thing into orbit which parks interceptors in polar orbits that will hit each of the targets. Then it re-enters and returns to base.

        Another option is recon - this thing could be launched at any inclination to get to any point in the earth quickly and then be able to return to base more quickly with cross-range capability.

        Those are just some wild guesses. Wings do give you options - no sense having them unless your mission demands them.

        Single orbit?

        Even the prototype is planned to fly for weeks.

        Payload in orbit with cross range re-entry capability allows for retrieval of payload. Or DELIVERY of payload.

        With a fleet of these, a few would always be within range is to almost any land mass on earth, on less than an hour's notice.

        After all, if you can put the wheels on the hash marks at the end of any runway, you could also but the entire vehicle through any given window of any given building.

      My logic (against a rival spacefaring nation): If you build it on a satellite, a strategically deployed paint fleck can render you defenseless until you can arrange for another satellite and launcher. Make a satellite maneuverable enough to dodge strategically deployed paint flecks and the fuel requirements may make your satellite huge and/or short lived. Put it on a space plane and you can dodge all you want, and just relaunch as needed if you don't dodge well enough.
       
      My logic (against rogue states): if you build it on a geostationary satellite and guess wrong as to where the next threat is coming from, you now need another satellite. If you build it on a network of satellites, you need the whole bloody network to not have blind spots. If you build it on space planes, you just fly them over whomever is the rogue of the moment.
       
      My logic (against the UN): satellites are subject to international treaties regarding the weaponizing of space. Planes-that-work-like-satellites are less so.

Unpowered intercepts on the sort of trajectory that would matter for an item that small would require truly amazing knowledge of spacecraft disturbances, not to mention precise knowledge of starting position and velocity.

      he craft is supposed to orbit Earth for several weeks, maneuver in orbit, and glide its way to a landing strip at Vandenberg Air Force Base, in California

      Really this just sounds like a fancier version of the SR-71/U-2 spyplane. Spy satellite are great things and can photograph pretty much anything given a long enough period of time; the problem is they're only going to be over the exact patch of dirt you're interested in perhaps once a week, and it might be cloudy (or night time!) when that happens.
       
      Enter the spy plane. The U-2 and SR-71 (and A-12, but that was discontinued in the 60's) are designed to get "now" pics without having to wait. Call up Bobby Hill AFB in California or Hank Hill AFB in Virginia and in 8 hours you can get an up to date photograph of exactly what's going on anywhere in the world.
       
      Now imagine you combine the two. The availability and speed of a spy plane, but the international benefit of staying out of of your enemy's airspace. Plus, due to the momentum it has, it stays in orbit for weeks, so after you buzz Moscow, you can do a course correction to your flying twinkie and hit up St. Petersburg, Beijing, Pyongyang, or Tehran to see where the weapons shipments are headed. Course corrections cost a lot of fuel for a satellite, which will be in orbit for years or decades, but course correction fuel on a reusable satellite that will only be up for a matter of weeks is cheap.
       
      Also it's a lot harder to hit a new sattelite with an unknown and changing orbit. The chinese have proven that they can knock a U-2 flying at 90,000ft out of the air [google.com].

      • The U-2's you speak of probably weren't at 90k (there was considerable speculation that Francis Gary Powers' altimeter had been tampered with as well), and had had their jamming equipment altered / sabotaged. They didn't just lob a couple of SAM's up and knock them out of the air.

    This is just conjecture. On a 'big' war day we are going to want to disable enemy satellites. We have ground based interceptors -- but there can be delays in launch windows, plus the 'bad' guys are going to be on guard and can take some evasive actions.

    How about our little X-37 with a cargo bay and manipulator arm goes and pays those 'nasty' satellites a visit right now and attaches a few pounds of high explosive with a radio detonator. When the war starts you push a button and they all disappear!

    Just in case they send a maintenance flight up, our little bomblets can also be equipped with a radio controlled 'spring' that detaches them from the satellite. No one is the wiser.

Make the orbit suitably eliptic and any debris that misses would burn up in the atmosphere within several orbits, and you can avoid collateral damage.

Orbital velocity at LEO is 7.8 km/s, so to shift from one satellite orbit to another would be almost as expensive as (and possibly more than) sending up a new rocket. I can't imagine the X-37 having a fuel capacity that much in excess of that required to reach LEO. And if that weren't enough to kill ya, the fuel costs of lifting that much more fuel to orbit would be insane (you could go to the moon on that delta-v budget!)

    First off, while the article is a good one, it was actually written before launch. After the launch, there have been some intriguing details, particularly the fact that NOBODY outside of the classified world has been able to actually locate it in the sky. Normally amateur skywatchers are pretty good at locating satellites after they've launched, but apparently not in this case. Here's two possible explanations for this:

    * the X-37B is testing low-visibility features, possibly either a stealthy payload shroud, low-visibility solar panels, or some other sort of camouflage/stealth system
    * One possibility posited by Jim Oberg (the article author) elsewhere is that this may be the first test ever of an atmospheric orbital plane change, a technique desired since the 90s or earlier, where a spaceplane uses its wings to dip into the atmosphere while travelling at hypersonic speeds to alter its trajectory. The X-37B apparently doesn't have a high enough L/D ratio to perform an extreme plane change (e.g. near-equatorial to polar), but it may be able to alter its trajectory enough to make it damn hard to track from the ground.

    Now, some people have been asking why a reusable spaceplane would be useful to the US Air Force. Some possibilities:
    * The atmospheric plane change capability mentioned above, which would allow the Air Force to deploy satellites into trajectories unknown by those observed. One major problem with satellites is that other countries typically know when they'll be overhead, so they just make sure that anything they're trying to hide doesn't occur during those hours.
    * If you add a retrieval arm or some other docking interface, you can potentially use the craft to alter the trajectory of existing satellites
    * Although the X-37B was launched on an expendable Atlas V rocket, the Air Force recently put out a solicitation for proposals [hobbyspace.com] for a first-stage Reusable Booster System utilizing a technique known as boost-back. With boost-back, after the booster boosts the payload and/or 2nd stage, it then does a 180 and boosts/glides back to a landing strip so that it can be easily reused. Lockheed Martin tested a secretive prototype of such a system (which they dubbed "Revolver") a couple years ago. If you combine such Reusable Boosters with a beefier successor to the X-37B, you have a rapid-launch reusable "surge" capability long desired by the Air Force. Such a surge capability could be useful when you need to quickly launch many satellites, such as when you need to deploy many satellites over a particular region in wartime or many of your satellites are knocked out by anti-satellite weapons or solar storms. Currently the Air Force has to wait for several weeks or months per satellite.

    For anybody interested in watching video of the launch (a rather beautiful launch of the Atlas V rocket), you can find it here: http://www.youtube.com/watch?v=AdCpuv9RCwE [youtube.com]

    Also, for those who are interested in finding out more, there's a lot of good discussion with plenty of current and former space professionals (including some posts by Jim Oberg, the author of the submission article) over at this NASASpaceFlight.com thread on the X-37B: http://forum.nasaspaceflight.com/index.php?topic=21122.285 [nasaspaceflight.com]

    The reason the shuttle is strapped onto the side of its launch stack is because it carries its payload internally. There are only two justifications for the engineering difficulties and operational hazards of this design. One is to have the expensive SSMEs attached to a recoverable part of the vehicle. The other is to give the vehicle the ability to recover payloads from orbit (read: steal enemy spy satellites.) With the end of the shuttle program looming, I'm guessing the Air Force is interested in maintaining that capability. And who knows... maybe they'll be nice and bring back Hubble, too.
