X-37B Robotic Space Plane Returns To Earth 55

Posted by Soulskill from the down-to-earth dept.
Kozar_The_Malignant writes "The secretive X-37B robotic space plane has returned to Earth after a seven-month mission. This was the vehicle's first flight. Looking like a cross between a Predator Drone and the Space Shuttle, it landed at Vandenberg AFB in California, which was to have been the military's shuttle launch facility. Speculation is that the X-37B is an orbital spy platform."

      I'm guessing fully-automated, since there's a long period of communication blackout during atmospheric reentry.

      The US will have great benefit from a new spybird. And until SpaceX's Dragon is proven, we don't have a cost effective competitor for the Soyuz capsule (even with a monopoly premium).

      Expect the "bumming rides" part to last only a year or so... Russia is in no position to be flying missions without massive support (meaning cash) from the USA, and we're in no position to be sending cash to Russia when China would rather us send it to them.

    • Why the myopic view? This is a test vehicle. Who's to say they aren't planner a larger, manned version? There's not much a robotic plane can do in space. Take photos? Satellites already do that job. Launch satellites? I would assume using conventional rockets is more efficient and cheaper. And even if this thing never ends up being manned, we're still going to learn a ton of valuable information from it.

      • It's a test bed for a reusable satellite. Make a stock platform which you can de-orbit and upgrade every few years instead of the Shuttle plucking and returning as was originally planned. You can also put one up for temporary missions instead of moving an existing bird.

    One of the big "it's not as logical as you'd think" headslappers of the space age is that the cost of launch dwarfs the cost of hardware. The space shuttle made a whole lot of sense with the idea of repairing satellites in space until you realized that with launch costs what they were, it was cheaper to sent up a new sat than fix an old one. The Hubble remains a very special case and I'm sure some people could make a case that it would have been cheaper to build and launch a series of Hubbles with incremental improvements on the usual $100 million a launch expendable vehicles than service it with $500 million a launch shuttles.

    Aaaanyway, the only useful mission that fits this flight profile is as a crew transfer vehicle. If it's just a spy sat, why bring it back? Back in the early days the spy sats actually took film and the cannisters were dropped down from orbit. Specially-equipped C-130's had to catch the cannisters before they went in the drink. A flyback cannister could make sense but the sats started beaming back their data yonks ago. The only thing I can think of is if they're trying to test out hardware and need to put the old eyeball on it directly to see how it's fared in space. But we've been doing a pretty good job designing sats without that kind of inspection for a long time. Color me stumped.

      It's also not true. Sure, the Shuttle used to launch a lot of low value hardware way back when, but if you look at commercial launch vehicles (both in the US and overseas), the launch price is usually somewhere around 10-20% of the total launch cost. This is really where launch costs are for serious applications. There's even some Shuttle launches in that price range (such as Hubble's launch or ISS components).

      I agree completely that the X-37 makes no apparent sense. The only argument I can come up with is that returning is just a nice side effect of its real purpose: inclination changes. Chaning altitude and period and phase is all relatively easy with onboard thrusters (and X-37 has an orbital maneuvering engine almost as big as the Space Shuttle's). But the amount of thurst needed to change oribal inclination from, say equatorial to ISS, is vast. I calculated it recently as being equivalent to the delta-v provided by an earth to LEO launch.

      What X-37 might be capable of is dipping into the atmosphere, banking, then thrusting back up to orbit. That's exactly what the Air Force's previous space plane was designed to do, the Dyna-soar. Once one has this capability, returning from orbit to a runway landing is a freebie since you already have the wings.

      The recently concluded X-37 test flight did not show an inclination change. But look for it on a future flight. This would allow extreme flexability in imaging enemy action at completely unpredictable times.

      • It doesn't make any sense because we don't know what it did up there.

        It might have been accessing other nation's spy satellites and mirroring what they were watching. It might have been a test flight for a orbital strike vehicle, changing orbits and simulating attack missions.

        Fact is you and I don't know what its for, but the USAF and the White House know enough about the mission to fund it, so we can't really judge to if it makes sense.

      • Do we know that an inclination change was not followed by a subsequent inclination change that returned the craft to the original inclination?

        • Yes. The amateur community had pretty good tracking on this thing, since it's so fascinating. They only ever lost it for a day or two at a time when it changed altitude.

      • The problem is - current generation spy birds have far more payload capacity (I.E. higher resolution sensors) than the X-37B *and* the ability to change orbital inclination. So, the X-37B doesn't seem to have any advantage there. Not to mention that the 37B is fairly easily trackable if you have a mind to - so any advantage of surprise would be short lived. (And to some extent predictable, it's hard to change your orbit enough to radically change your observation windows.)

      Something like this could be a quick replace for spysatellites since the technology to destroy/disable satellites with missiles and lasers has become more of an issue. Satellites aren't that maneuverable after all and tracking them due to their repetitive orbit isn't that difficult.

      Would be cool if you could put stuff like this in orbit with a cannon, but I guess that's still a long way off.

      Well, no. Except for fairly simple payloads, and payloads like comsats that are built more-or-less on an assembly line basis, the cost of hardware is generally on par with or dwarfs the cost of launches. That's one of the big reasons there's been no particular reason to drive down launch costs. (The extraordinarily low demand being another.)

      No. The answer is obvious.

      This shuttle vehicle is designed to retrieve satellites deemed too risky to fall back to earth in any shape or form.

      Also... It has the ability to retrieve foreign satellites. This is more of a chilling effect as they seem to want everyone to know they have this ability so before Russia or China decided to send up anything of note in the spy department that they will have to be aware that the Americans can pull it down to find out what makes it tick.

Yes, they're probably going to utilize it as an incredibly dynamic observation vehicle and stuff it full of sensors, but the fact that it's now a proven technology (and was up for seven months, with multiple controlled orbit changes!) is a big milestone. We don't see very many leaps forward in space technology now adays, but this is one of them.
