NASA Spacecraft enters orbit around an asteroid.
NASA’s Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.
Dawn, which launched in September 2007, is on track to become the first spacecraft to orbit two solar system destinations beyond Earth.
Dawn will study the asteroid, named Vesta, for a year before departing for a second destination, a dwarf planet named Ceres, in July 2012. Observations will provide unprecedented data to help scientists understand the earliest chapter of our solar system. The data also will help pave the way for future human space missions.
