"Human beings hardly ever learn from the experience of others. They learn; when they do, which isn't often, on their own, the hard way."
- Robert Heinlein

| Trajectory Ship | ||
| A spaceship that takes the minimum energy route to another planet, with the passengers weightless. |
| You ought to be glad the Evening Star is a high-gravity ship instead of a trajectory job. Then you’d really be sick, and no foolin’.”
“How’s that?” “I mean that she accelerates or decelerates her whole run. Have to, because she carries cabin passengers. If we had been sent by a freighter, it’d be a different story. They gun ’em into the right trajectory, then go weightless for the rest of the trip. Man, how the new chums do suffer!” He chuckled. |

Compare to other spaceships, in particular, compare to a ship with Lyle drive from Heinlein's Stranger in a Strange Land (1961), a continuously operating acceleration providing "weight" to passengers.

'Our planes are going to start bringing in bales of discarded plastics...'
'... completely forgetting the ship at sight of the awesome figure and great head of the giant Gaut...'
'So, Ender, we will now begin your education.'
'What strange sensitivity! What an amazing development of science was manifested in every move and act and word of this Robot!'
'Forget the head atop it, the legs below, feet, arms, hands. It compels erasure.'
'That explains how it was so easy for me to remain motionless in midair or to perch on a flagpole in imitation of a giant bird, even in the windy city of Chicago.'
