My friend Andy told me about a cool space site, NasaSpaceFlight.com. Lots of useful stuff and interesting discussions on the forums. The CEV (Crew Exploration Vehicle) is NASA's proposed next-generation spacecraft that will take crews to the ISS, the Moon, and perhaps even Mars. In one post, an Orbiter user (gladiator1332) showed some Orbiter images of a biconic CEV, commenting that Orbiter provides the means to visualize these next-generation craft in 3D (not to mention you can fly them!). Another application!
Biconic refers to a special crew capsule shape that would provide some controllable lift on reentry without the weight penalty of wings. Francis Drake developed an add-on for Orbiter using this shape, and it's really cool. I played with it a bit, and the picture shows it docked at the ISS (unusual through-the-heatshield docking port). I haven't yet installed the files to mate this to Simcosmos' prototype SRB-derived booster.
NASA's programs may be delayed by funding problems - but not in Orbiter!
