After Almost Two Years, The Air Force's Mysterious X-37B Space Plane Lands (space.com) 116

An anonymous reader quotes Space.com: The record-shattering mission of the U.S. Air Force's robotic X-37B space plane is finally over. After circling Earth for an unprecedented 718 days, the X-37B touched down Sunday at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida -- the first landing at the SLF since the final space shuttle mission came back to Earth in July 2011... The just-ended mission, known as OTV-4 (Orbital Test Vehicle-4), was the fourth for the X-37B program... The 29-foot-long (8.8 meters) X-37B looks like NASA's now-retired space shuttle orbiter, only much smaller; indeed, two X-37Bs could fit inside a space shuttle's cavernous payload bay...

Most of the X-37B's payloads and activities are classified, leading to some speculation that the space plane could be a weapon of some sort, perhaps a disabler of enemy satellites... But Air Force officials have always strongly refuted that notion, stressing that the vehicle is simply testing technologies on orbit. "Technologies being tested in the program include advanced guidance, navigation and control; thermal-protection systems; avionics; high-temperature structures and seals; conformal, reusable insulation, lightweight electromechanical flight systems; and autonomous orbital flight, re-entry and landing," Captain AnnMarie Annicelli, an Air Force spokeswoman, told Space.com via email in March.

        Not really. It's just another instance of the media and politicians picking up a nice new technical-sounding word and not bothering to check what it means before using it. Of course the sheer volume of mis-use does in time change the actual meaning, but I don't think "refute" is quite that broken yet.

      Probably included bleeding edge spy electronics in actual service, the only reason for such an extended mission beyond exercising for stress test reasons new electron8cs and materials, which Nasa would have covered already in ongoing missions.

        Actually it was launched to temporarily replace two of the mind control satellites, which had been put out of action by collisions with space debris. The new replacements were launched from the government's secret facility in Dwaynesville, PA. Unfortunately there was a brief interruption of service in late 2016, around November 8, but there don't seem to have been any major consequences.

        Using the atmosphere to obtain enhanced orbital maneuverability is my guess. With the retirement of the SR-71, if some event happens that needs to be observed from an air/space vantage point, you either need to wait for dozens of hours for a drone or piloted reconnaissance aircraft to arrive, or wait for more hours for some satellite's orbit to rotate into sight and try to watch from an angle of several hundred miles away.

        Yeah, or to put it another way, "What do you think a secret phase conjugate tracking system is for?"

        One obvious stepping stone towards weaponizing space would be developing advanced surveillance and precision tracking technology, and experimenting with it without actually building the weapon part. After all, once you build the weapon and use it, you're committed. Everybody knows you have it, and if the outcry is too strong, you've lost the PR war, and you're never going to get money for new R&D. So it makes sense to limit your laser testing to labs (because location doesn't matter much for that), and test only the tracking/optics in a real-world environment until you get that part exactly right, then merge the two after you have all the key pieces for your superweapon.

        I'm not saying they're doing this, because how would I know, but that's certainly what I'd do if I wanted to pull a fast one on the general public. Just saying.

      The Air Force is just protecting their IP . . . they are worried that Über will hire away one of the Air Force's colonels with stolen design materials, and offer a competing Secret Space Plane Service, that can be hailed with an App!

      Actually, the really secret news, is that, although the Secret Space plane took off unmanned, . . . it landed with three passengers!

      The "guests" will be working on the Air Force's super secret Götterdämmerung project, which is being developed at the follow-on virtual site to Area 51. The virtual site is not in one place, but uses advanced distributed technology, based on Git, Blockchain and BitTorrent in an Internet of Things. If one node of the virtual site gets destroyed by Russian Hackers, the other nodes can recreate the work of node.

      The Air Force stated that the purpose Götterdämmerung is "no what you think it is", and that they also have no idea what you think.

    I've observed this satellite, OTV4, in orbit several times over the last couple years; it being large and reflective enough to be easily seen by the unaided eye. I figured the day would come when it would be brought in but since it was a secret project the landing date was anyone's guess. Glad it was a happy landing.

      The Air Force had their fingers deep in the Shuttle program - mostly to it's detriment. Cross-range landing capability, payload size and a host of other goals were stuffed into the project making it one of the largest human kludges ever designed.

      Now they get to play with their own toys. If we're very nice, they might let NASA take a peek. But probably not. There are both valid reasons for keeping the military technologically ahead of the civilian space program and some institutional / paranoia reasons.

      Hopefully everyone remembers enough of the Shuttle program to not try to make a one size fits all high technology vehicle.

        Like the F-35.

        But with the F-35, it is the Marines, not the USAF, that are ruining it.
        The V/STOL capability has required a lot of compromises in other capabilities.

        • For example the dysfunctional (and almost useless even if functional) gun, the abysmal helmet, and the serviceability?
          Yeah, those were the marines...

          US pork procurement procedures are what ruined it, and pretty much every other US military project in the last 20+ years, not the marines.

          Meanwhile the Russians and the Chinese are making actual progress..

        • The V/STOL Marine version of the F-35 is completely separate from the Air Force and Navy versions.

          • The V/STOL Marine version of the F-35 is completely separate from the Air Force and Navy versions.

            Yet the ability to create a V/STOL version required compromises in the airframe, engine placement, and many other areas of the base design, that weaken all the versions. Likewise, the Navy's need for an airframe that can handle steam catapult launches and arresting cable landings, means that the Air Force is getting a heavier airframe than they need, resulting in a slower plane with a reduced range.

            • It reminds me of an attempt in the early '60s to do similar. We ended up w/ the F4 Phantom II. Pretty much living proof that a pig *can* fly given sufficient thrust.

              Through upgrades, re-thinking tactics, and training, it was turned into an adequate, if expensive weapon.

              It appears that every generation needs to make the same mistakes as their forebears.

        I'm thinking winged space vehicles have some advantages like returning high value items to an air force base with a hard surface so it can easily be towed to a building. No need to call the Navy to fetch out of water or drag item out of a dusty desert. Or do a high risk mid-air retrieval like in the early days of film return recon sats. However, scaling up to Shuttle size increases costs way beyond anyone wants to pay for it.

      Anyone who tracks pieces of space junk, I would think.

      Look at this device in context. China, Russia and the US are all working on hypersonic weapons. With such a weapon, you could potentially strike any point on the Earth within an hour, combining the global reach of an ICBM and the precision terminal guidance of a smart bomb, without the political ... well, fallout you'd get from the brute force of a nuclear strike.

      You obviously could weaponize a space drone, but once you'd actually used it the cat would be out of the bag. Everyone would know you're stationing weapons in space, so next time there's a chance of a conflict all your space assets are a target, which of course is especially bad for the country with the most space assets. Oh, don't get me wrong. You'd surely keep your options open, probably even discreetly study the problem, especially in an cost-is-no-object procurement atmosphere.

      But the thing that a military who's increasingly emphasizing precision from afar needs most is to know is the right chimney to drop the bomb down. So while I wouldn't be surprised if the program did have some space-based weapons goals, I'd be really surprised if it didn't have intelligence-gathering goals.

  • I think it's primary mission is as a roving spy satellite platform which can change orbit. Maybe even as a platform for the deployment and possibly retrieval of micro satellites. Lets say you want to observe an area that you think is active only when typical satellites are not overhead. You could launch a micro sat with stealth tech to do short term undetectable observation. This is highly likely I believe. Less probable but maybe even more useful would near silent reusable small sats that could sync bac

If the 2 satellites weren't on a collision course already, the bullet has no chance of hitting anything. Not to mention the recoil will put your satellite out of alignment instantly.

          Why, indeed? [popularmechanics.com]

          These days there are such things as guided bullets. It's not hard to imagine a large projectile (in the tens of mm range, perhaps) which would be guided not by fins, but by jets. Then you could make a course correction.

          Not to mention the recoil will put your satellite out of alignment instantly.

          Obviously, you take that into account.

          You're probably right anyway, though. You'd use something more like a rocket and less like a bullet. For example, you could use a Gyrojet [wikipedia.org].
