论文摘要
NASA黎明航天器于2007年9月从Cape Canaveral起飞，在Delta II Rocket上方，开始了雄心勃勃的Vesta and Ceres之旅，Vesta and Ceres是太阳能系统中最大的小行星水库中的两个最庞大的世界。在黎明发射之前，对维斯塔和谷神星的地球结合观察发现了有趣的特征 - 从坚固的形状到Ceres的脆弱水层 - 但这些物体仍然是模糊的光线，即使是通过最强大的望远镜的镜头。随着Dawn对Vesta（2011-2012）和Ceres（2015-2018）的探索，这两个世界开始焦点。出现了令人叹为观止的细节，这些细节涉及大型碰撞雕刻的维斯塔（Vesta）在内部主带中释放了大量材料，从而提供了在地球上回收的重要陨石家族的来源。 Ceres的复杂地质可能与地球和火星的竞争相媲美，它推出了最近的Cryovolcanic活动。这本书专门针对这些亮点，以及黎明任务的更多发现。到2018年黎明完成任务时，我们对太阳系形成的理解已经大大发展，这要归功于新的理论模型，以及新的陨石地球化学数据，对Vesta和Ceres的黎明观测提供了对协同解释模型和数据的新的，重要的限制。黎明遗产的更广泛含义是在一系列专门的章节中提出的。编辑希望这本书能够为年轻一代以及更多经验丰富的研究人员提供成功的参考。多亏了Dawn，我们当然学到了很多东西，但是我们知道我们几乎没有刮过主要皮带小行星可以告诉我们太阳系黎明的表面。
The NASA Dawn spacecraft took off from Cape Canaveral in September 2007 atop a Delta II rocket starting an ambitious journey to Vesta and Ceres, the two most massive worlds in the largest reservoir of asteroids in the Solar System, the Main Belt. Prior to the Dawn launch, Earth-bound observations of Vesta and Ceres revealed intriguing features--from Vesta's rugged shape to Ceres' tenuous water exosphere--, but these objects remained fuzzy speckles of light even through the lenses of the most powerful telescopes. With Dawn's exploration of Vesta (2011-2012) and Ceres (2015-2018) these two worlds came into focus. Breath-taking details emerged of how large collisions sculpted Vesta liberating massive amounts of material in the inner Main Belt, providing the source of an important family of meteorites recovered on Earth. Ceres' complex geology, which may rival that of the Earth and Mars, unveiled recent cryovolcanic activity. This book is dedicated to these highlights, and many more discoveries of the Dawn mission. By the time Dawn completed its mission in 2018, our understanding of the formation of the Solar System had greatly evolved thanks to new theoretical models and to a new trove of meteorite geochemical data, and Dawn observations of Vesta and Ceres provide new, vital constraints to synergistically interpret models and data. The broader implications of the Dawn legacy are presented in a series of dedicated chapters. The editors hope this book will serve as a solid reference for the younger generations as well as for more seasoned researchers to successfully pursue future exploration of the Main Belt. We certainly have learned a lot thanks to Dawn, and yet we know that we have barely scratched the surface of what Main Belt asteroids can tell us about the dawn of our Solar System.
