Descent to HAMO

Descent to HAMO
Descent to HAMO Dawn’s spiral descent from its second mapping orbit (survey) to its third (HAMO). The two mapping orbits are shown in green. The color of Dawn’s trajectory progresses through the spectrum from blue, when it began ion-thrusting in survey orbit, to red, when it arrives in HAMO. The red dashed sections show where Dawn is coasting for telecommunications. Compare this to the previous spiral. NASA / JPL-Caltech
