Washington : NASA has approved a second extension of the Dawn mission at Ceres, the largest object in the asteroid belt between Mars and Jupiter.

During this extension, the spacecraft will descend to lower altitudes than ever before at the dwarf planet, which it has been orbiting since March 2015, the US space agency said on Thursday. The spacecraft, which has already completed 10 years of spaceflight, will continue at Ceres for the remainder of its science investigation and will remain in a stable orbit indefinitely after its fuel runs out.

Dawn completed its prime mission in June 2016, and its first extension was also approved that year.

A priority of the second Ceres mission extension is collecting data with Dawn's gamma ray and neutron spectrometer, which measures the number and energy of gamma rays and neutrons, NASA said.

This information is important for understanding the composition of Ceres' uppermost layer and how much ice it contains.
