Okay, how about Pluto

• Voyager=16 years to Pluto. A 1.6 year trip would take dV = 5.8e12m/5e7 s ~100 km/s

  • Isp M_rocket/M_payload
  • 100,000 1.1
  • 10,000 2.7
  • 1,000 22,000
  • 400 72,000,000,000

• We aren’t going to use chemical rockets if we want a fast Pluto flyby larger than a pencil eraser.
