But the Sojourner's historic trek was not accomplished without significant
and careful practice and preparation. JPL's Sojourner team, which
controlled the Mars rover vehicle, counted on Silicon Graphics
supercomputers to create 3D virtual models of the Martian landscape for
test-driving Sojourner before sending its daily movement commands.
Likewise, the JPL multi-imaging processing laboratory relied heavily on
Silicon Graphics workstations for storage and processing of Pathfinder's
low-resolution data into images, as well as systems used to analyze
atmospheric and geophysical data.


The most unpredictable event surrounding Sojourner's every move, however,
was the incredible Web-mania that swept the Internet. |
