C3 Energy
Convert characteristic energy into hyperbolic excess speed and parking-orbit departure delta-v.
Departure delta-v
3,736.12 m/s
536 m/s above parabolic escape
Hyperbolic excess
3.46 km/s
speed at infinity
Perigee speed
11.46 km/s
post-burn speed
C3 injection geometry
The parking-orbit burn raises perigee speed above local escape speed, leaving a hyperbolic excess velocity.
C3 12.00 km2/s2
Hyperbolic excess
3.46 km/s
square root of C3
Perigee speed
11.46 km/s
speed immediately after injection
Escape portion
3,200 m/s
circular speed to parabolic escape
C3 portion
536 m/s
additional speed above escape
