Amateur astronomers have located the officially secret orbit of the X-37B, affectionately known as The Flying Twinkie. This is a reusable, unmanned orbital space plane that experts believe will carry on research for the Department of Defense after the manned shuttle fleet is grounded. It was launched back in April into low-Earth orbit on a mysterious mission. I’m going to set an alarm for early morning and try to get a peek if the skies are clear. You can track the orbit and see the X-37B yourself using Chris Peat’s excellent website, www.Heavens-Above.com
Also, this X-51A Waverider hypersonic scramjet launches May 25th. [link]
The X-37 shuttle is doubtless rooted in the development of surveillance, but the X-51 has serious potential as a weapons platform. The USAF has openly stated their desire to get a cruise missile on target anywhere in the world in under an hour. This thing is a step in that direction].
