The plaque is mounted on the back of Spirit's high-gain
antenna, a disc-shaped tool used for communicating directly
with Earth. The plaque is aluminum and approximately six inches
in diameter. The memorial plaque was attached March 28, 2003,
at the Payload Hazardous Servicing Facility at NASA's Kennedy
Space Center, Fla. Chris Voorhees and Peter Illsley, Mars
Exploration Rover engineers at NASA's Jet Propulsion
Laboratory, Pasadena, Calif., designed the plaque.

You know, the last time NASA temped fate like that, we got Apollo 13.
