X-37B Likely Spying on China’s Space Station

We may finally have a clue what the U.S. Air Force’s secret space plane, the X-37B, is up to on its record breaking mission in the heavens. Amatuer satellite trackers have noticed that the robo-shuttle’s orbital path is nearly identical to China’s brand new space station, Tiangong-1, which was launched in September.

Remember, the X-37B can stay aloft for nearly a year and is capable of changing its orbits around the Earth. These features, combined with the secrecy surrounding its missions have prompted many people to speculate that it is a spy craft capable of launching small spy satellites and snooping on other nation’s satellites up close.

“Space-to-space surveillance is a whole new ball game made possible by a finessed group of sensors and sensor suites, which we think the X-37B may be using to maintain a close watch on China’s nascent space station,” Spaceflight editor Dr. David Baker tells the BBC.

Remember, OTV-2, the second of two X-37Bs, launched last March and recently surpassed its official endurance of 270 days in space. It’s very plausible that Air Force officials decided to keep the bird aloft past its max endurance in order to get a better look at the Chinese space station. Tiangong-1 will receive its first human occupants later this year and is intended to serve as a prototype for several larger Chinese space stations.

From the BBC:

The current mission was launched on an Atlas rocket and put into a low orbit, a little over 300km up, with an inclination of 42.79 degrees with respect to the equator – an unusual profile for a US military mission which would normally go into an orbit that circles the poles.

The X-37B’s flight has since been followed from the ground by a dedicated group of optical tracking specialists in the US and Europe, intrigued by what the vehicle may be doing.

These individuals have watched how closely its orbit matches that of Tiangong.

The spacelab, which China expects to man with astronauts in 2012, was launched in September with an inclination of 42.78 degrees, and to a very similar altitude as the OTV.

“The parallels with X-37B are clear,” Dr Baker says in Spaceflight, the long established magazine of the British Interplanetary Society.

“With a period differential of about 19 seconds, the two vehicles will migrate toward or against each other, converging or diverging, roughly every 170 orbits.”

  1. Except that it's not. They intercept orbits at 8 km/s, and their orbits planes are 60 degrees apart. All they are doing is looking at the same thing on the ground.

  2. Bloopers in Space:

    "A horrendous error appears to have been made by a well-respected British spaceflight society, which reportedly is about to publish an article claiming that the X-37B, the secret Pentagon space plane, is shadowing the recently launched Chinese prototype space station, Tiangong-1, to spy on it in flight.

    But that’s ridiculous. The American plane’s orbit is at a steep angle with respect to that of the Chinese space station. When the two vehicles pass, they do so at speeds of up to 8000 meters per second, making it practically impossible for one to gather intelligence on the other."

  3. And even if it were looking the station, what is so important about the uninhabited metal cylinder that the US has to have it under constant observation at considerable expense?

  4. Interesting; speculative at best.

  5. Chicom is just a frankenstein monster the US greedy coprs and politicains created.

  6. Noooo DT, you drank the Kool-Aid! Seriously go over to SpaceDaily and read Morris Jone's article on WHY THE X-37B IS NOT SPYING ON THE CHINESE.

  7. Good they can shoot it down too then LOL.

  8. Thats the problem with blogs. You have one careless story seconded by another blogger and so on

  9. The Brits are just as bad at fact checking as our American media, Ive noticed.

  10. Let's face it… Nobody is going to snoop on a spacelab in orbit that they can't readily do it on the ground either through human intel or hacking into the control station's computers (although it's not easy).

    One just can't help but love the X37-B and the "cult-like" movement it created among "watchers"… :)

  11. If the Americans want to spy on China’s Tiangong-1, surely it would be far less conspicuous if Obama were to simply teleport into the as yet unmanned space station and just have a look around.

  12. Does a week go by without DT trying to invent some reason why the X37B means our space program isn't just pathetic ?

    Now we have the ability to peer enviously at the Chinese.

  13. Best thing they can do is make anotherone …..
    Bigger and put American's BACK into space….

  14. Say hello to the fourth front of a future war with the Chicoms. Control of the space equals control over everyone's satellites. It is important we as a powerful country keep the PRC from designing more advanced anti satellite weapons and design our own.

  15. I have limited experience with orbital mechanics. But even so I immediately rejected this story as nonsense. What was the mission? To sneak aboard and short sheet the bunks? Tack weld a latch shut on the hatch?

    Speaking strictly about the smaller satellites in this article, these may be physically small platforms but with newer technologies they can be very large and heavy duty working platforms for many different things, not only for aerial photography. They can make up a very fast and efficient network for all types of electronic communications and surveillance. Point to point, worldwide and anything in between. Navigation controlling and monitoring. I would love to be working on these myself.

  17. 8000m/sec is sufficient to gather signal intelligence… intercepts start from 150km away and perhaps they want to appear as streaking particle/debris on chinese fuselage mounted cams.

    This should be top secret why would they release this info if it says something about the best country in the world spying on someone which we probably are but who cares its for our benefit.

  19. There's an old saying, There's little bit of lie in every truth and little truth in every line. I think that applies to this system best. I'm sure we are using it for exactly what the USAF says we are. I am also absolutely sure there are other things it can do they aren't bothering to tell us.

  20. What happens if the X-37 surpasses its maximum endurance? Does that put a hazardous amount of stress on the spacecraft?

  21. Why answer the question other than saying NO. Then again, why ask the question in the freaking first place, and expect to get an answer. Especially one that is YES.

  22. Go Air Force.(May the "Force" be with you!

    This is designed as a lifeboat for the ISS all astronauts are not shuttle pilots. This space plane can only return to earth since it carries re-entry fuel enough to land. It can land automatically without any pilot input. It will rescue the entire station astronaunts in one load. I dont know any way it could do anything else especially spy purposes that other satillites are designed to do.

  24. What spying and what spy plane is everyone talking about? There's no espionage going on. It's called reconnaissance which is quite legal by international law.

  25. Mr. Monske, I think you are confusing the X39 with the NASA X-38 Crew Return Vehicle (CRV) project which was cancelled years ago due to budget cuts [NASA factsheet: http://www.nasa.gov/centers/dryden/news/FactSheet… ]. The vehicles' design, shape and function are different (X-38 provided seating and protection for human beings). X-39 is a DoD multi-use unmanned orbital maneuvering vehicle and responsive space/space lift capability. Regards.

  26. the X37 could release limpit type tracking modules to be with the Chinese ss.
    it could practice tracking and logging it as well.
    run prediction models of where it will be and when.
    and it's probably the X37 is spying on everyones sats and active space gear.
    what is a system to do in space for 270+ days other than
    look around? i bet it's pretty jammed full of recon gear.

  27. Appreciating the hard work you put into your blog and detailed
    information you offer. It’s nice to come across a blog every once in a while that isn’t
    the same unwanted rehashed material. Wonderful read!
    I’ve bookmarked your site and I’m including your RSS feeds to my Google account.

  28. Hi! I realize this is kind of off-topic but I had to ask.
    Does managing a well-established website such as yours take a massive amount work?
    I am brand new to writing a blog but I do write in my diary daily.
    I’d like to start a blog so I can easily share my personal
    experience and views online. Please let me know if you
    have any kind of ideas or tips for new aspiring bloggers.
    Appreciate it!

  29. I know this web site presents quality depending content
    and additional information, is there any other web page which offers such
    things in quality?

  30. Hi there! I know this is kind of off topic but I was wondering if you knew

    where I could locate a captcha plugin for my comment form?

    I’m using the same blog platform as yours and I’m having problems finding one?

    Thanks a lot!

  31. Write more, thats all I have to say. Literally, it seems as though you relied on the video
    to make your point. You definitely know what youre
    talking about, why throw away your intelligence on just
    posting videos to your site when you could be giving us something informative to read?
