"Always listen to experts. They'll tell you what can't be done and why. Then do it."
- Robert Heinlein

| Gravity Well | ||
| The surface of a planet. |
| He was the pilot and engineer, the only other Terrestrial on Mercury. When you dove this far down into the sun's monstrous gravitational well, you couldn't take a big crew along. |

This expression quickly became a favorite of veteran sf writers; Heinlein, Clarke and Niven used it within a few years. Here's Niven using it as the subject of a short story, At the Bottom of a Hole (1966):
"The hole." Garner knew enough Belters to have learned a little of their
slang.
"The very one. His first instinct must have been to change course.
Belters learn to avoid gravity wells. A man can get killed half a dozen
ways coming too close to a hole. A good autopilot will get him safely
around it, or program an in-and-out spin, or even land him at the bottom,
God forbid. But miners don't carry good autopilots. They carry cheap
autopilots, and they stay clear of holes."
"He must have been on course for Luna when we found him. Ceres was behind
him with the radar. Our ships were ahead of him, matching course at two
gee. His mining ship wouldn't throw more than point five gee, so
eventually they'd pull alongside him no matter what he did. Then he
noticed Mars was just ahead of him."

Okay, sf fans. If you could have some art created from a science fiction sentence, what sentence would you pick?
'There were the cleaners, with large padded feet, who were apparently polishing their way the whole length...'
It's fascinating to me how the Apollo program forced people to think outside their usual boxes.
'Some will combine in place to form more complicated structures, like excavators or centipedes.'
'the hair-fine wire going deep into Owen's brain, down into the pleasure center.'
'There was a dim whirring, and the spheres tipped and began to rotate...'
'The houses are prefabricated units... and they sell at the flat rate of five hundred dollars a room — set up.'
