Skip Owen of NASA Launch Services, right, is demonstrating an app that can run on a mobile device such as a smartphone or tablet computer. The app is depicting the launch of the TDRS-M satellite on an Atlas V rocket. The demonstration took place during a briefing focused on preparations to launch NASA's Tracking and Data Relay Satellite, TDRS-M. The latest spacecraft destined for the agency's constellation of communications satellites, TDRS-M will allow nearly continuous contact with orbiting spacecraft ranging from the International Space Station and Hubble Space Telescope to the array of scientific observatories. Liftoff atop a United Launch Alliance Atlas V rocket is scheduled to take place from Space Launch Complex 41 at Cape Canaveral Air Force Station at 8:03 a.m. EDT Aug. 18.
