Less than a year from its rendezvous with dwarf planet Ceres, Dawn is continuing to make excellent progress on its ambitious interplanetary adventure. But once it gets to Ceres, just how will it go into orbit? Marc Rayman explains.
The majority of Dawn's time in the Ceres approach phase will be devoted to continuing ion-powered flight. Let’s take another look at how this remarkable technology is used to deliver the adventurer to the desired orbit around Ceres.
Now more than halfway through its journey from protoplanet Vesta to dwarf planet Ceres, Dawn is continuing to use its advanced ion propulsion system to reshape its orbit around the sun. Now that the ship is closer to the uncharted shores ahead than the lands it unveiled astern, we will begin looking at the plans for exploring another alien world.
