That is what I said?QuantumPion said:A rocket in LEO still needs 11 km/s to escape but it is already going 7 km/s due to its orbital velocity. Otherwise it wouldn't be in orbit.Escape velocity is a property of position only, I think. A rocket in LEO still needs ~11km/s as escape velocity - it is just easier to reach it.
Well, it is completely different from air drag or similar types of drag.Yes, gravity is considered as a type of drag in this sense.
Starting from what? Every interplanetary mission uses the velocity of Earth (~30km/s), and most rockets use the rotation of Earth (up to ~500m/s) to begin the mission.sophiecentaur said:Is it not true to say that no spacecraft has ever been given the full 'escape velocity' with its motors?
