Dawn Discovery mission to Vesta and Ceres: Present status
Dawn, the ninth Discovery mission, is a journey to the main belt asteroids Vesta and Ceres to attempt to understand the building blocks of the solar system and the processes occurring at the solar system s earliest epoch. It does this with a spacecraft that utilizes ion propulsion to reach its targets and to maneuver into orbit about these bodies. It carries a framing camera, a visible and infr...
متن کاملDawn completes its mission at 4 Vesta
The Dawn mission was designed to test our hypothesis about the origin and evolution of the early solar system by visiting the largest differentiated basaltic asteroid, 4 Vesta, believed to be a survivor from the earliest times of rocky body formation. Observations from orbit show that Vesta is the parent body of the Howardite, Eucrite, Diogenite meteorites. Vesta has an iron core and a eucritic...
متن کاملDawn Mission to Vesta and Ceres Symbiosis between Terrestrial Observations and Robotic Exploration
The initial exploration of any planetary object requires a careful mission design guided by our knowledge of that object as gained by terrestrial observers. This process is very evident in the development of the Dawn mission to the minor planets 1 Ceres and 4 Vesta. This mission was designed to verify the basaltic nature of Vesta inferred both from its reflectance spectrum and from the composit...
متن کاملMoon search algorithms for NASA's Dawn Mission to asteroid Vesta
A moon or natural satellite is a celestial body that orbits a planetary body such as a planet, dwarf planet, or an asteroid. Scientists seek understanding the origin and evolution of our solar system by studying moons of these bodies. Additionally, searches for satellites of planetary bodies can be important to protect the safety of a spacecraft as it approaches or orbits a planetary body. If a...
متن کاملSpectrophotometric properties of dwarf planet Ceres from the VIR spectrometer on board the Dawn mission
Aims. We present a study of the spectrophotometric properties of dwarf planet Ceres in the visual-to-infrared (VIS-IR) spectral range by means of hyper-spectral images acquired by the VIR imaging spectrometer on board the NASA Dawn mission. Methods. Disk-resolved observations with a phase angle within the 7◦ < α < 132◦ interval were used to characterize Ceres’ phase curve in the 0.465–4.05 μm s...
