Just getting back from my latest trip to the National Space Symposium and Colorado State University (CSU) in Fort Collins, CO. Some of the videos we did at the Space Symposium are already up at Engineering TV. The ones from CSU will be up soon.
Sierra Nevada's Dream Chaser and the Boeing CST-100 compete with SpaceX's Dragon capsule. We didn't get a video interview with them but they did have one of thier actual capsulses on display. These Low Earch Orbit (LEO) systems are designed to dock with the International Space Station (ISS). They can be smaller than the shuttle because the ISS construction is complete.
Not everything was hardware at the show. DigitalGlobe takes advantage of the high-resolution earth imaging satellites to provide comprehensive geo-information. They are utilizing GPU arrays to extract more information from this data.
