(...) No it doesn't. It takes a tremendous amount of CHEMICAL fuel, but you need to use something with a much higher specific impulse. The problem is that your chemical exhaust is going WAY too slow, hence you're not transferring much momentum. (...) (25 years ago, 16-Dec-99, to lugnet.off-topic.geek)
