Hasta La Vesta!
12:00 p.m. Pacific Time

Dawn virtual flight
Watch the video simulation of Dawn cruising around Vesta!

We've spent a phenomenal year at Vesta, gathering data close up and far away with Dawn's international payload of instruments. Our mission extension means the spacecraft's time at the mini-planet concludes in late August, after gaining additional views of its north polar region. Soon we will be saying Hasta la vista, Vesta, to our favorite giant asteroid as we begin our journey to dwarf planet Ceres!


How are we celebrating?

Connect with Dawn team members and fellow Dawn mission fans in real time! Dawn scientists and engineers will share mission stories and answer questions submitted via Facebook and Twitter in a live, interactive video event.

From Dawn's Chief Engineer, Dr. Marc Rayman:
Dawn has completed the final intensive phase of its extraordinary exploration of Vesta, and has now begun its gradual departure. Propelled by its uniquely efficient ion propulsion system, the probe is spiraling ever higher, reversing the winding path it followed into orbit last year.  

- Excerpted from July's Dawn Journal


Read this summer's Dawn Journals for a great overview of Dawn's instruments' impressive accomplishments this year:

✓ June 30, 2012: Data gathering during the spacecraft's final, high altitude orbits of Vesta.
✓ July 25, 2012: Find out about Dawn's long good-bye as it readies to leave Vesta for Ceres. 


Get on-the-minute mission and science updates during this unprecedented transition as Dawn gets ready to say good-bye to giant asteroid Vesta and begin its remarkable journey to another member of the main asteroid belt, dwarf planet Ceres: a first for humankind!
