Amateurs Spy On US Spy Plane

arshadk writes with this excerpt from Wired's Danger Room: "The X-37B has generated intense interest, long before it ever left the ground. Boeing originally developed the 29-foot unmanned craft — a kind of miniature Space Shuttle — for NASA. Then, the military took over in 2004, and the space plane went black. Its payloads were classified, its missions hush-hush. ... You can even see the space plane for yourself: The X-37B is traveling in a slightly elliptical orbit more than 200 miles up, swooping from 43 degrees north latitude to 43 degrees south."

      Here's a summary:
      Each time the X-37B is launched a bunch of amateurs make a game out of finding it in orbit. It took a month to find it using telescopes on the first mission, but only 4 days on the current mission. It is currently in a very low (lower than the space station) non-polar orbit, which is unusual for spy satellites, because it will never cross large areas of the planet. So they presume it is used for spying on specific areas on this mission, likely the Middle East as it has good coverage of that area. Basically all that's known is its orbit, not what it is capable of nor what it is actually doing.

      It is the orbital inclination that makes the Molniya orbit attractive to the soviets. The high inclination combined with the ~12 hour elliptical orbit gives it a high dwell time near one of the poles (can be either pole, but not both).

      If you meant "new units of measurement are being invented", you might have a point. We don't use the Roman mile any more, and nobody has ever really used the American gallon (there's a lot of profit to be made through accumulated rounding errors in your favour).

If I had to pick one achievement of the French above all others that has benefitted the world, I'd say SI by a landslide. They have done a lot, but a lot of it has had mixed results. SI is unambiguously good for both science and wider society. The biggest problem SI has had is that Imperial units (the system America uses a derivative of, ironically) tend to be closer to what you might call "natural" units. That's where most of them came from. The problem is, you can't do anything much with Imperial units EXCEPT measure natural objects unless you use Base 4 (which is when many - but not all - Imperial units become easier to work with).

And pushed in scifi ever since; hey, it does look really familiar and reassuring...
      About the only sensible thing maybe going for it seems to be testing / ability to maybe do noticeably larger, per delta-V & fuel required [2], lifting inclination changes. Maybe.

Spaceplanes can be seen as analogous to flying boats (not many of those around now); Catalina at best (& hopefully), Spruce Goose at worst. Imagine how much further we could be without STS (a craft obsolete long before its first mission; first automatic orbital rendezvous & docking taking place in the 60s) or Buran (pushed by ignorant Soviet generals as a "counterpart" to nonexistent strategic advantage of STS; engineers wanted to do something very different)

  19. Some speculation by Anonymous Coward · · Score: 0

    I doubt they sent it up just to look down on Libya. The US can do that with normal manned aircraft and UAVs because of the UN resolution establishing the NATO no fly zone. I think the expense of launching and recovering a spy satellite only makes sense when it is not possible to send an aircraft overhead (violating a sovereign country's airspace) and the observations cannot be obtained by other airborne standoff sensors.

    As for secrecy, nothing can be kept absolutely secret once it leaves the development lab. This includes the stealth aircraft, etc. Any real-world use will result in observation. The US could use various cover stories to try to confuse observations and preserve some degree of secrecy though. For example in the '60s with the Aurora spy satellites, the NASA had an elaborate biological program to send up small animals and study the effects of space travel. The biologists in the program had no idea that they were part of an elaborate cover story. Prior to launch, the biological payload would be replaced by a camera payload. The satellite would fly its mission and be recovered and the animals returned to the biologists for study. The only reason we know it was a cover story is the CIA declassified the program after the end of the cold war.

    It might be possible the flight path over Libya and the middle east is a cover story and the satellite contains payload for some other form of observation in the other direction, such as to gather intelligence on Chinese or Russian spy satellites which would have a similar orbit to observe the US. I have no knowledge one way or another, this is just my little thought experiment.

  21. Sense and non-sense about the X37-B by Dr+La · · Score: 1

    As usual, quite some non-sense appears in some of the comments here about the orbit of the X-37B and it's "manoeuverability"

    First: in terms of reconnaissance opportunities, a 43 degree orbit gives you no edge over a polar orbit. On the contrary, while a polar orbit brings any latitude within reach for reconnaissance, a 43 degree orbit does not as latitudes above 43 degree are less well covered (and far North or south latitudes aren't covered at all).

    Note that for targets below 43 degree latitude, it really doesn't matter whether the satellite is in a 43 degree, 63 degree or 90 degree (polar) inclination orbit: all these orbits will bring such a target in reach, and the 43 degree orbit has no extra benefit compared to a 63 or 90 degree orbit.

    So it is nonsense to think that the 43 degree inclination orbit has been chosen to have a "better" look on a target near 43 degree latitude. A 90 degree inclination orbit would cover such as target just as good.

    Instead, the 43 degree inclination has probably been chosen to maximize coverage of the X-37B orbit by US tracking and control facilities. So, a very prozaic explanation connected to the experimental nature of the craft, and the fact that it frequently re-boosts (it has to: it is in a low orbit and hence subject to quick decay).

    Another frequent non-sensical remark about the X-37B is that it supposedly would be "more manoeuverable" than the typical reconnaissance satellite: and somehow able to "quickly get over a target" if necessary. Again, this is a wrong view on how orbital dynamics and the dynamics of target coverage work. The X37-B might have wings and behave like an airplane in the atmosphere near landing: but in space, it is just a satellite subject to the same orbital laws as any other satellite. Like any satellite, it will cover any target within reach of the orbital inclination at least twice a day. And you just don't "steer" a spaceship to a target within an hour: it is not similar to flying an airplane (unlike suggestions in Battlestar Galactica or Star Wars). You change the orbital period and/or inclination and this determines when and how the satellite (X37-B in this case: but it is the same for any other satellite) will encounter a target, about twice a day.

    Please note that, contrary to assumptions to the contrary often made, regular reconnaissance satellites like the Keyholes and Lacrosses frequently manoeuvre as well. They have to, to maintain their orbital constellation. Nothwithstanding this frequent manoeuvring (they do so multiple times a year) they stay operational for many, many years (Lacrosse 2 was finally de-orbited last week after being operational for 20 years, with very frequent manoeuvering during those 20 years). So the X37-B doesn't really have an edge in sense of "manoeuverability" over any other satellite, contrary to what many people seem to think. The frequent manoeuvres the craft makes are manoeuvres to maintain orbital altitude, and this has to do with the low orbit (= high drag, high decay) the craft is in. It are not manoeuvres to change the orbit to quickly target new targets. That idea, is simply wrong and originates with people who have no clue about orbital dynamics in space.

    The only real edge the X-37B has over other satellites is that it enables you to sent up and then retrieve payloads. For the rest, it cannot do more than any conventional satellite can do.

    The X37-B OTV-2 passes over Tripoli as well:

    X-37B OTV-2: 7 passes

    Lacrosses with their orbital inclination of 50/57 degrees make as much passes per day as the X-37B with it's 43 degree orbital inclination. There really is no reason to think that the choosen inclination has anything to do with optimizing Libya coverage. The more so since the previous X-37B mission, which was before the Libya revolution started, also had an orbital inclination near 40 degrees.

    As I mentioned in another comment, the choosen inclination most likely has to do with optimizing coverage by the US tracking facilities.
