Dawn climbs to space on Sept. 27, 2007, from Cape Canaveral Air Force Station. We described earlier this year how Dawn flew to extended mission orbit 6 (XMO6) for a new campaign of photography and other measurements. On every Sept. 27, we reflect on this unique interplanetary adventure. Another way to investigate the progress of the mission is to chart how Dawn’s orbit around the Sun has changed. Dr. Marc D.
