- Yup. For the *Discovery* they are gaseous-core fission engines-- in
- other words, a fission reactor running at a *really* high temperature,
- 20,000 degrees F (11,000 C). (If I were a journalist, I probably
- would have written 11093.33 degrees C...) Liquid hydrogen flows past
- this to serve as exhaust fluid and to help keep the graphite walls
- cooled. Consult a book on advanced space propulsion for details.

- technical advisor on the film and this article is a great source of
- behind-the-scenes information and pictures (fifty pages' worth!).

- I don't know of anyplace where the propulsion of the *Leonov* is
- discussed, but it's reasonable to suppose they use gas-core engines
- too.
-
- I always thought this technology was a trifle advanced to be ready in
- only 2001, but remember that Kubrick's people were busy little beavers
- in the 34 years following 1967-- they had dug out underground hangars
- on the Moon for their spacecraft, with elevators, had started regular
- Pan Am service to orbit, had built half a space station (but Clarke
- pointed out in the Fifties in *Islands in the Sky* that you would
- finish building the wheel FIRST, and THEN spin it up!), and by 12
- January 1992 had achieved artificial intelligence.
-
- It is sad to think that *they* were supposed to be *us*. :-(
