Cartography of Asteorid 4 Vesta and Dwarf Planet Ceres

Kurzfassung

The Dawn mission mapped the surface of the asteroid 4 Vesta over a period of nearly ten months from altitudes below 700 km [1]. Image data from the Dawn Framing Camera [2] were collected in a Survey imaging campaign at the beginning and in three primary mapping phases: High Altitude Mapping Orbit One (HAMO-1, September 29 - October 31, 2011) and Two (HAMO-2, June 24 - July 24, 2012) near 700 km altitude and the Low Altitude Mapping Orbit (LAMO, December 15, 2011 - April 30, 2012) near 200 km altitude. During the two HAMO campaigns, the surface of Vesta was almost completely mapped in the clear plus seven band-pass filters. Dawn arrived at dwarf planet Ceres in March 2015 and will map Ceres in similar orbit phases as Vesta, the orbit altitudes will be approximately twice as at Vesta.
