After unraveling many secrets of the solar system for about 11 years, the Dawn spacecraft of NASA will end its journey since now its fuel supply has ended. Sent to study protoplanet Vesta and dwarf planet Ceres, the spacecraft now misses communication sessions. Lasted two years more than originally planned, the spacecraft is now unable to turn itself to the sun to get recharged and keep in touch with the earth. Starting in 2007, the spacecraft covered around 6.9 billion km and had a commendable journey. In 2011 it became first to orbit asteroid belt between Mars and Jupiter. It sent data which enable scientists to study the two planets like worlds which evolved in a very dissimilar fashion. It also helped create a possibility that the dwarf planets might have or even do host oceans or other water sources. All the data collected from Dawn will help scientist analyze as to how planets grow and differentiate and also where and how the life commenced in the solar system. Ceres and Vesta have conditions and data which is of huge interest to scientist and thus the spacecraft will be disposed of quite carefully by the NASA team. It is said to remain for 20 years in the orbit which will last for around 50 years. NASA now bids goodbye to Dawn with a heavy heart.
