Dawn Journal: Explaining Orbit Insertion

Marc Rayman • May 06, 2014 • 4

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.

Marc Rayman updates us on Dawn's status and explains how the spacecraft is actually getting closer to Earth at the moment as it moves deeper into the asteroid belt.

Dawn Journal: Maneuvering Around Ceres

Marc Rayman • March 03, 2014 • 2

Continuing its daring mission to explore some of the last uncharted worlds in the inner solar system, Dawn remains on course and on schedule for its rendezvous with dwarf planet Ceres next year.

Dawn Journal: Onward to Ceres

Marc Rayman • February 01, 2014 • 4

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.

Dawn Journal: Planning for the Ceres Approach Phase

Marc Rayman • January 01, 2014 • 4

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.

Dawn Journal: Equidistant from Vesta and Ceres

Marc Rayman • December 06, 2013 • 1

Gliding smoothly through the main asteroid belt between Mars and Jupiter, Dawn continues to make good progress on its ambitious mission of exploration. It is patiently but persistently pursuing Ceres, the second destination on its interplanetary itinerary.

Dawn Journal: Thrusting Toward Ceres

Marc Rayman • November 03, 2013 • 1

Deep in the main asteroid belt between Mars and Jupiter, Dawn is continuing its smooth, silent flight toward dwarf planet Ceres. Far behind it now is the giant protoplanet Vesta, which the spacecraft transformed from a tiny splotch in the night sky to an exotic and richly detailed world.

Dawn Journal: Sixth anniversary of leaving Earth

Marc Rayman • September 28, 2013 • 2

On the sixth anniversary of leaving Earth to embark on a daring deep-space expedition, Dawn is very, very far from its erstwhile planetary residence. Now humankind's only permanent resident of the main asteroid belt between Mars and Jupiter, the seasoned explorer is making good progress toward the largest object in that part of the solar system, the mysterious dwarf planet Ceres.

Dawn Journal: Distant interplanetary adventurer

Marc Rayman • August 30, 2013 • 1

Traveling confidently and alone, Dawn continues to make its way through the silent depths of the main asteroid belt. The interplanetary adventurer is on its long journey to the uncharted dwarf planet Ceres, by far the largest of all asteroids.

Dawn Journal: Craving Power

Marc Rayman • July 30, 2013 • 5

Ion propulsion is not a source of power for Dawn. Rather, the craft needs a great deal of power to operate its ion propulsion system and all other systems. It needs so much that...we crave power!!
