Am. I the only person troubled by the fact the man on the cover has lost the lower half of his body?

No, that was the first thing I noticed, too.

So who needs legs in microgravity? It's an early attempt at accommodating the disabled in an environment which renders their disability irrelevant.

It saves on mass, too. Double points for Human Growth Hormone-challenged amputees.

I read this when Jimmy Carter was President, and remember very little about it. But Google serves, where memory does not, to explain that the bottom half of the spaceman is inside the crate, pedaling his eponymous* bicycle.

*Eponymous, that is, for the magazine version of the story, "A Bicycle Built for Brew."

Is this in the same future history as "Tales of the Flying Mountains?"

There seems to be a bit of parallel story development; IIRC, one of the shorts in TotFM features movement of an asteroid via fancy gravitic drive, and the frame tale is taking an asteroid on an interstellar flight.

ETA: I don't remember Martians in TotFM, though. Probably just Anderson being parsimonious with worldbuilding, then.

The stories in TotFM were written between 1963 and 1970: first flyby of Mars finally killed off Dejah Thoris and the rest of 'em in 1964.

I never did get how the magic gravity drive was supposed to work. Okay, yes, assume you can screen or otherwise negate the gravitational force of other bodies. How does this give the MGD the sort of propulsion that you get from stepping on the gas and turning the steering wheel?

_acceleration_ certainly doesn't seem in the cards.

If your magic gravity drive were selective you could just turn off the attraction of Earth and the sun, for example, and let yourself fall toward Mars.

Memory says that one of the Tom Swift Junior books had a space drive that worked either like that or as a really long range tractor beam, but I can't remember which.

A really long range pressor beam, actually. Tom Swifty dubbed this invention the repelatron. First seen in use underwater; only later was it made into a space drive.

Was there even any handwaving about how the repelatron was supposed to work?

That was how HG Well's Cavorite worked: you kept a sheet of it between yourself and the Earth while leaving the side facing the Moon (or, in this situation, Mars)clear. I'd think it would take a _long_ time to fall to Mars, though...the initial gravitational pull would be feeble.

I get 3.35E-11 g's, for the present distance between Earth and Mars (3.6E11 meters).

But once you're outside of Earth's atmosphere you're halfway to anywhere, surely...
