To sum up:


The Dawn spacecraft has been orbiting the dwarf planet Ceres, 61,000 kilometers of its surface, as reported by NASA. Scientists want to watch for a little over a year to try to decipher its early history and evolution. Ceres is now about 500 million miles from Earth. "Since its discovery in 1801, Ceres was considered first planet, then asteroid and eventually dwarf planet. Now, after a journey of 4,900 million kilometers in seven and a half years.


In my opinion:

Throwing away spacecrafts with the aim to investigate the universe it is really useful. We don´t know hardly nothing about it, how many planets there are or how are they? It s really good question.
The spacecraft named "Dawn" may rich this oblective, and hopefully cientifics will know something more about universe.
