Space Updates
End of the Shuttle Program
• Was the shuttle program a huge mistake?– 135 flights in 30 years– Simpler designs bypassed– $209 billion in costs– 2600% more expensive per flight than initially projected
• What's next?– Private Efforts
• SpaceX • Bigelow
– Space Nuclear Power badly needed
Zubrin Trashes Vasimir
• Main objection is claiming Vasimir is required to go to Mars– Saying it is puts off many other program aspects
• As elecric thrust tech it is not that impressive– Existing ones are 70% efficient and Vasimir is barely at 50%
• Requires high temperature superconductors for major missions– We simply don’t have them
• Requires (Mars) a nuclear power system 20x more powerful and 100x better power/weight

Russian Nuclear Space Projects
• Space-based nuclear power station– 150 to 500 KW– Lasts 10-15 years– For moon or Mars
• Associated projects– Large space platform replacing many satellite (2018)– Energia – nuclear powered space tug– Spaceship with nuclear engine
• $16.7 million to this this year• Design due next year• Funding of $580 million to be built over 9 years.
