</CENTER>

Working with JPL scientists, the Geometry Center is producing a solar
system visualization package which can be used in conjunction
with <A HREF="crafter.html">Crafter</A>
to visualize missions during the design stage.  The
Orrery contains bitmapped images of all the major planets and moons,
places them in their correct positions at any given date and time, and
will evolve them at a specified rate. Within this system, a three
dimensional model of a spacecraft can be placed on a computed
trajectory. Other features which may be added are the visualization of
the invariant manifolds.
