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
