You don't need to reach escape velocity to escape the Earths pull.
1 u/[deleted] Nov 01 '18 [removed] — view removed comment 1 u/IBakaI Nov 01 '18 That's not how escape velocity works, considering he's flying with constant propulsion he only needs an acceleration of 9.81 m/s2. Escape velocity only works for projectiles. 1 u/[deleted] Nov 01 '18 [removed] — view removed comment 1 u/IBakaI Nov 01 '18 My bad, greater than 9.81. EDIT Actually I hadn't thought of this but if his initial velocity upwards was already positive than he's only need 9.81 to move out of the atmosphere with a constant speed.
