Who Shrank the Shuttle?

If you see a picture of the X-37B unmanned spaceplane, you would be forgiven for mistaking it for a slightly modified Space Shuttle. If you look closer you realise it’s a mini-version of a Shuttle, around 9m (29ft) in length and 5 tonnes (11,000 pounds), with a payload of your average pickup truck.

Here is a picture of it in its hanger [CREDIT: space.com].

 X-37B mini shuttle

Looks awesome. I like the V-shaped rear wings. Looking at this I’m thinking all that money spent in Shuttle development wasn’t as wasted as I thought.

Two have been built so far (reportedly), and one has been in orbit around Earth since December, although no one knows exactly what it’s doing up there.

The X-37B went into orbit on top of an Atlas 5 rocket from Florida’s Cape Canaveral on December 11 2012. The current mission is designated Orbital Test Vehicle-3 (OTV-3), as the third classified mission under the US Air Force’s X-37B program.

The little robotic vehicle is on the USAF’s books as USA-240.

The vehicle lands on a strip, just like its bigger (defunct) cousin, but even more impressively it does so autonomously. Pretty cool, huh? I thought maybe I could sneak into the back in a spacesuit for some spacewalking next time it goes up, but then realised I could never hope to pack enough oxy-mix – the little craft was up in orbit for 469 days for OTV-2. That’s a long time to hold your breath.

OTV-2 ended on a special strip at Vandenberg  on June 16 last year, although the jury is out as to whether OTV-3 will end there or back at the good old shuttle strip at Kennedy Space Centre.

Anyone heard anything about what the X-37B’s doing up there?

  1. Nada. No info at all. Taking high resolutions pictures, presumably. Or picking up and retreiving satellites doing the picture taking. But there aren’t even any good rumors around.

  2. Actually, the space zombies are waiting for their friends to come and pick them up. Area 51 bids them a fond farewell, after all those years…
