NASA’s Jet Propulsion Laboratory (JPL) will host a live-streamed Science Chat at 2 p.m. EDT Friday, September 7, during which experts will talk about the role of the agency’s Dawn spacecraft in studying the beginning of our solar system, and the approaching end of its 11-year mission.
- Jim Green, NASA chief scientist
- Carol Raymond, Dawn principal investigator at JPL
- Marc Rayman, Dawn mission director and chief engineer at JPL
The public can ask questions on Twitter using the hashtag #askNASA or in the comment section of the JPL Facebook page.
NASA launched Dawn in 2007 to learn more about the beginning of the solar system. During its mission, the spacecraft studied the asteroid Vesta and dwarf planet Ceres, celestial bodies believed to have formed early in the history of the solar system.
The mission aided scientists in characterizing the early solar system and the processes that dominated its formation. Dawn is the only spacecraft to orbit two deep-space destinations, a feat enabled by the efficiency of the spacecraft’s ion propulsion system.
