Glossary of Terms:								

DSM	Deep Space Maneuver							
ESB	Earth Swingby (Gravity Assist)
MA	"Mean Anomaly (i for ""initial"", f for ""final"")"
MODMP	Momentum Dump
RND	Rendezvous Braking Maneuver
TCM	Trajectory Correction Maneuver

The orbital elements are given in the Sun-centered (heliocentric) ecliptic of J2000 system. a is semi-major axis, q is perihelion distance, e is eccentricity, i is inclination, W is longitude of the ascending node, w is argument of perihelion, and MA is the mean anomaly at the initial (i) and final (f) Julian dates given.
