The DART mission is NASA’s first planetary defense test mission. It will be launched at the end of this month.
The objective of this mission is to test a newly developed technology. This involves hitting a spacecraft with an asteroid and using the resulting energy to change the asteroid’s path.
In this mission, a new technology designed to stop an asteroid coming towards Earth in future will be tested.
The spacecraft used in the test is aimed at a small moon (Moonlet) called Dymo Pharcos.. It orbits a large asteroid called Didymos.
A moonlet is a small natural or artificial satellite.
