TWIK012: Space Travel

A very brief overview of the basic mechanics involved in space travel.

Equations and Constants

Time in hours to accelerate: Hours = Δv x .0455 / Acceleration in Gs
Time in days spent coasting: Days = Distance (in AU) x 1076 / Δv
Earth’s Orbital Velocity: 18.5 mps
Earth’s Escape Velocity: 6.96 mps
Constant acceleration: Δv required = √(distance / acceleration) x 1482 x acceleration
Constant acceleration time: Hours = Δv / (21.8 x acceleration)

Future Episodes
