Mission Configuration – 100 gram [Blockton] [OPS] • Launch Vehicle • Dnepr-1 Rocket • Converted intercontinental ballistic missile • Operated by the International Space Company Kosmotras • Selected because of its low cost and high mission reliability
Low Earth Orbit Performance 300 kg 900 km [Blockton] [OPS]
[Blockton] [OPS] • Launch Site • BaikonurCosmodrome, Kazakhstan • Although launch site is substantial distance north of the equator, launch performance and cost retain attractiveness • Insert Map/Picture/Diagram of Launch Facilities
Mission Configuration – 10 kilogram [Blockton] [OPS] • Launch Vehicle • Dnepr-1 Rocket • BaikonurCosmodrome, Kazakhstan
Mission Configuration – Arbitrary [Blockton] [OPS] • Launch Vehicle • Falcon 9 • Designed by Space ExplorationTechnologies (SpaceX), USA • Although vehicle has not flown, mission reliability looks promising • Reduced stages • Simplified turbopump engines • Selected because it achieved lowest cost per kilogram to Low Lunar Orbit (LLO)
Low Earth Orbit Performance 9953 kg 400 km [Blockton] [OPS]
[Blockton] [OPS] • Launch Site • Cape Canaveral Air Force Station, Florida • Insert Map/Picture/Diagram of Launch Facilities
Design Alternative - Locomotion [Blockton] [OPS] • Spring Cannon • Ground Launch • 45° initial angle • Eliminated because g-force at launch exceeds Space Ball’s structural capability
G force at Launch Spring Length for 30 g Take-off 540 km 18 m spring 18 km 118 g’s G force upon Landing 721 km 30 g’s [Blockton] [OPS]
