QUESTION:
How much total change in velocity was required for the Pathfinder to get
from the parking Earth orbit to Mars orbit? (i.e. How much change in
velocity was provided by the PAM-D upper stage?)
 
ANSWER from Pieter Kallemeyn:
An additional 3.7 km/s (or 3700 m/s) was needed to leave the parking orbit
(circular, 185 km altitude) and place Mars Pathfinder onto a Earth-Mars
transfer trajectory.  This was done by re-starting the 2nd stage of the
Delta II launch vehicle, immediately followed by ignition of a solid-motor
3rd stage (PAM-D).
