13. Space Express Overview • Mission Background • Hardware Systems • Flight Software • Mechanical Systems • Communication Systems • Ground Software

14. Mission Objectives • Get to Space Fast • Training Mission • Flight Testing Hardware and Software • Flight Testing Processes

15. Launch Provider • Lunar Rocket & Rover Co. • Launch vehicle: Shadow 1 DART Sounding Rocket • Launch site: White Sands, NM • Flight time: 4 mins. • None Recoverable Payload • Launch window: Nov. 15 – Dec. 15 • Delivery date: Sept. 15

16. Launch Requirements • Weight will determine the final altitude of the rocket. • The payload must remain off while on the launch pad until the rocket has started accelerating. • A re-settable RBF pin must be used. This pin must physically disconnect power from the payload when inserted. • An acceleration switch must be used to turn on the payload once the rocket has started accelerating, the payload cannot be active until the rocket has begun accelerating • The payload must be able to survive the environmental conditions of the Shadow 1 Rocket • 47 G’s Acceleration, 2.1 sec. burn reaches 5,000 ft • 6 Hz Spin • 100C • Max Altitude of 150 Km
