  • No Astronaut has ever gotten past the 'Asteroid Belt'.
  • They don't. They haven't gone that far yet. http://en.wikipedia.org/wiki/Asteroid_belt
  • They look both ways first.
  • No astronaut has yet been http://www.answerbag.com/q_view/990618out to the asteroid belt, which is between Mars and Jupiter. But don't let film presentations conduse you: the asteroids are millions of miles apart, and the danger of hitting any of them is essentially zero. A number of unmanned probes have gone past the Belt without trouble.
  • Astronauts were not yet there, but some probes did it. The probability of a collision is considered very low: "The first spacecraft to traverse the asteroid belt was Pioneer 10, which entered the region on July 16, 1972. At the time there was some concern that the debris in the belt would pose a hazard to the spacecraft, but it has since been safely traversed by 9 Earth-based craft without incident. Pioneer 11, Voyagers 1 and 2 and Ulysses passed through the belt without imaging any asteroids. Galileo imaged the asteroid 951 Gaspra in 1991 and 243 Ida in 1993, NEAR imaged 253 Mathilde in 1997, Cassini imaged 2685 Masursky in 2000, Stardust imaged 5535 Annefrank in 2002, and New Horizons imaged 132524 APL in 2006. Due to the low density of materials within the belt, the odds of a probe running into an asteroid are now estimated at less than one in a billion."
