NASA's X-37

jacobm wrote with a story about the NASA/Boeing project. Called the X-37, it's not like other X-class planes - it can actually stay in orbit. The purpose of the plane is to test "new reusable rocket technologies". Apparently, it designed to reach only a mere Mach 25, but a Boeing VP says another goal is to make space travel as affordable as travelling by plane. The article also includes a neat little insert with pictures of the other X-class planes.
