Ad Astra?

• To do interstellar flight, we need to approach relativistic speeds, say, 12% c (which doesn’t do much to our clocks)

  • Isp Mass_rocket/Mass_payload
  • 2,000,000 6
  • 1,000,000 50
  • 500,000 2670
  • 150,000 264,000,000,000

• Conclusion we aren’t going to do Interstellar travel any time soon
