"Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today -- but the core of science fiction, its essence has become crucial to our salvation if we are to be saved at all."
- Isaac Asimov

| Magsail | ||
| An interplanetary craft that uses magnetic fields to catch the solar winds for propulsion. |
| "How fast will this thing go?" the rigger wondered.
"Depends on current density, orientation, and a bunch of other factors programmed into the RAM pins here." He flourished the goat-case, careful not to shake it. "If you're sailing large before the wind, your acceleration is about a thousandth of a gee." "That don' sound so fast, friend." Jimmy grinned, having said almost the same thing to Hobie last year. "Not compared to an SSTO main engine, right. Get a couple of gees squashing your bag during a lift, right? The sail gives a gentler push, but it keeps on pushing. You don't run out of fuel unless the sun goes out; in which case fuel is not your major concern. Bottom line is: a magsail can get you to Mars in about the same time it took the Mayflower to cross the Atlantic." |
