Title: Unveiling a Mysterious World - Dawn Approaches Ceres Abstract: Dawn spacecraft was gravitationally captured by Ceres on March 6, officially started its year-long mapping activity of this mysterious world. The recent unequivocal discovery of water vapor on Ceres, which is possibly the second largest water reservoir inside Jupiter in the solar system, suggests an active planet. However, we know little about this only dwarf planet in the inner solar system more than 200 years after its discovery. The images collected by Dawn during approach at 4 km/pixel have already shown an object that is more interesting and puzzling than we had originally thought. I will briefly introduce the background of studying Ceres, discuss the early images from Dawn.
