US Air Force's Mysterious X-37B Space Plane Sets New Record For Time In Space (cnn.com) 50

"An Air Force X-37B spaceplane just completed its 718th day in orbit, making it the longest mission yet for a secretive military test program," reports CNN: The US military has launched five uncrewed X-37B spaceplanes into orbit over the past decade, and each flight has been longer than its predecessor...

What is known is that the military is using the planes to develop reusable spaceflight technology. Officials don't necessarily want to reuse the same X-37B plane multiple times, but the Air Force designed the craft to try out new navigation systems as well as methods for reentering the Earth's atmosphere and for landing safely back on terra firma. The X-37B is also popular among space fans because of its unique design. The planes, which look like miniature space shuttles, launch into orbit atop powerful rockets and then break away to carry out their mission. When their duties are complete, they swoop back toward Earth and touch down horizontally on a runway, like a commercial airplane or space shuttle orbiter coming in for landing...

The current X-37B plane in orbit, called OTV-5, was launched to space in September 2017 on a SpaceX Falcon 9 rocket. The previous flight, for OTV-4, was 718 days long and ended in May 2017.

    What are they doing up there circling the Earth? I'll bet they are up to no good!

    • We have a space force now, apparently
      • Assuming you are referencing the Space Command that was in the news recently, it should, perhaps, be pointed out that it was created in 1985...

        The latest iteration has fewer than 300 people assigned to it, so what we have now a General Officer billet commanding what amounts to a reinforced company (a captain's billet)....

      Looking down at France, India, the UK, Germany, Brazil, Vietnam and seeing what they do when they don't expect a US spy sat to be above them..
      The nuclear power plant gets strange truck visits going to a "lab".
      Strange shapes rolled at mil airports and quickly rolled back in again. In time with traditional US spy sat hours.
      Nobody expects the US space plane.

    The US military has launched five

    The current X-37B plane in orbit, called OTV-5

    It's a secret. Are we sure there are five of them? Maybe it's like the prank where you release three pigs in your high school. Paint #1, #3 and #4 on them and watch the antics ensue as they try to locate #2.

    Or like Seal Team Six.

    • It's a secret. Are we sure there are five of them?

      Getting something into orbit takes a big fucking rocket. There's people all over the place that's going to notice a rocket, even if they launched them in the dark of night. There's going to be airplane crew that see it, and launches show on flight notices to keep planes from running into them. These things show up on weather radar. They make a lot of noise from a bright flame shooint out the bottom. These observers are going to be not only people in the USA but also nations that are not so friendly wit

        Oh, and once in orbit these satellites can be tracked with not much more than a lawn chair, binoculars, a notepad, calculator, stopwatch, a few beverages, and time.

        Maybe. Supposedly, these have the capability to maneuver in orbit. So if you don't know how many there are or how many are up at one time (one big fucking rocket looks pretty much like the next), the USAF can play a game of 3 card monte to keep the orbits difficult to analyze. Odds are that such capabilities probably won't be tested until they are needed. Or the shuffle trick will be given away. But I could easily understand them keeping the number of available vehicles secret.

      I was thinking of Heinz "57 varieties".

      • In reality it took them 1624 tries to get the recipe right for Heinz "57" but they realized that nobody was going to buy Heinz 1624 and so they made up the number 57 because it sounded much better. Thus we have Hienz 57. It has nothing to do with the number of varieties.

      'OTV-5' is the mission designation not the vehicle designation, and so far there are known to be two X-37B vehicles (both of which are known to have flown 2 missions each), but which one is flying OTV-5 is currently unknown so theres a potential for a third to be in existence (but its more likely to be the third flight of vehicle 1).

      5 to look down 24/7 globally? Whats the math on max height and how wide an area they can see?
      How many are needed in a space fleet for global look down?

    It's the longest space mission that landed back on Earth. The record for time in space (for a man-made object) belongs to Vanguard 1 [wikipedia.org], launched in 1958 and still in orbit (albeit dead and incommunicado). Sputnik 1 stayed in orbit for 3 months before burning up in the atmosphere. Sputnik 2 stayed up for 5 months before burning up (dog and all, although Laika was long dead due to excessive temperatures). And Explorer I reentered the atmosphere in 1970.
  • Stupid miniature shuttle goes up and stays up shorter than most satellites, looks like the shuttle, acts like the shuttle, but can only have hamsters as passengers. I think the only thing that is amazing about this entire thing is that they are actually wasting money on it.
    • You turned it into news by posting about it. If you completely ignored it it would be less newsworthy.
    • Actually it doesn't act like the Shuttle since the Shuttle had to be flown by a pilot. This acts like the Soviet Buran shuttle which flew on autopilot.

      As for being a waste of money it depends on what they want to do with it. Maybe it will grab old US satellites and bring them down for upgrades?

      When they bring it back to Earth the weightless hamster dance could be a real money-maker.

      When the hamsters return, they discover that a civilization populated by gerbils.

  • I'd imagine that a large driver for such a system would be the ability to load nuclear weapons into these craft. The ability to descend the plane from orbit, anywhere about the Earth, with a load of sensors and nuclear weapons, would yield a powerful advantage in war.
    • This is an absurd application for nuclear weapons delivery. We have perfectly good, nearly invulnerable - and dirt cheap - means of dropping bombs on people for more than half a century.

              What they say its for, on the other hand (medium-duration recoverable space experiments) is a perfect fit, and replaces the same thing from the shuttle days for far less cost, and far longer possible mission duration. Why is that so hard to believe?

      • Yes, and there's half a century worth of defensive technology developed against threats such as ICMBs, bomber, submarine or ship deployment.

        New platforms don't eliminate the old, but supplement. As such, the above mentioned platforms will continue to have a role to play for the foreseeable future.

        Why do you assume this vehicle couldn't be used for multiple purposes? It seems naive to think that this thing is funded by the Air Force yet doesn't the design doesn't have considerations beyond conducting 'm
      • Whoops, I also intended to address why it's hard to take the Air Force statements at face value. Politics and strategy would be sufficient cause to withhold such information from the public.

        Now, I'm not saying that I have any information more than you, nor that I'm confident that this is the purpose of the vehicle. However, I've learned to be very cautious regarding statements coming from people that feel a higher duty to the cause they serve, than truth. I mean, that's part of what we pay these people fo
      • Ever heard of a fractional orbital bombardment system? Hell, Rods from God? This little bastard could be the first stage of the Prompt Global Strike program. Even if it's got a load of science data, if it could change its orbit to intersect the ground at orbital velocity more or less, it'd be a pretty nasty kinetic-kill system in a pinch.

    Any cool plane should have an X + number in its name, unless it's a Blackbird.

You know you've landed gear-up when it takes full power to taxi.

Working...
