QUESTION: 
How long is the journey to Mars?

ANSWER from Cheick Diarra on November 18, 1996:
The time of flight to Mars depends on many factors and varies from mission
to mission. For example, for the Mars Pathfinder, the jouney would be
about 7 months, while the Mars Global surveyor will take about 10 months
to get there. 

ANSWER from Pieter Kallemeyn on February 6, 1997:
A space shuttle or rocket would take 6 to 11 months to get 
to Mars from Earth. The range of time depends on where the 
Earth and Mars are in their respective orbits.
