Here's a news snippet I wasn't aware of:
QUOTE In a little-known footnote to space history, Voyager 1's Titan booster shut down prematurely after liftoff. The powerful Centaur upper stage was barely able to compensate, reaching escape velocity 3.4 seconds before running out of fuel. Luckily, Voyager 1 would still reach Jupiter and Saturn as planned. However, had the underachieving Titan been used instead for Voyager 2, whose trajectory hinged on getting maximum performance from its booster, its eventual encounters with Uranus (in 1986) and Neptune (in 1989) would have been lost. By pure chance, Voyager 2 got the better rocket. Seems like the Uranus and Neptune encounters hung by a thread in more ways than one... -------------------- "I got a call from NASA Headquarters wanting a color picture of Venus.
