QUESTION:
How much does it cost to run the operations for MGS and MPF?

ANSWER from Donna Shirley on February 11, 1997:
Pathfinder's cost is $14M for one year of operation.  MGS cost is about
$20M per year for approximately 3 years, although during part of that time
we will also be operating the Mars Surveyor 98 orbiter and lander.
