  1. NASA’S DART Mission Context: NASA will be launching its first-ever planetary defence test mission, the Double Asteroid Redirection Test (DART). The DART spacecraft will be launched by the SpaceX Falcon 9 rocket. Mission Objectives: The mission is to test new technologies that will be prepared if an asteroid approaches Earth in the future. The goal is to test a newly developed technology that could cause a spacecraft to collide with an asteroid and divert it. After the mission collides with an asteroid, scientists will use a series of telescopes deployed in different parts of the planet to study its impact on the asteroid's orbit. The DART will be the first demonstration of dynamic impactor technology that transforms the movement of asteroids in space. The spacecraft's target is a small moon named Dimorphos (Greek for "two forms"). Dimorphos orbits a giant asteroid named Didymos (Greek for "twin"). The collision is expected to occur between September 26 and October 1, 2022. About the mission: The DART is an inexpensive spacecraft. It has two solar cells and uses hydrazine propellant to steer the spacecraft. It carries 10 kg of Xenon and will be used to demonstrate in space a new thruster from an engine called the NASA Evolved Xenon Thruster Commercial (NEXTC). The NEXT grid ion thruster system offers a combination of performance and spacecraft integration capabilities, making it uniquely suitable for robotic missions in space. In addition, the spacecraft is equipped with a high-resolution imager called the Didymos Reconnaissance and Optical Navigation Asteroid Camera (DRACO). The images will be sent to Earth in real-time to help investigate the surface of collision sites and Dimorphos (target asteroids). The DART will also carry a small satellite called the LICIA Cube (a lightweight Italian

  2. CubeSat for asteroid imaging) or the CubeSat. LICIA Cube is supposed to take pictures of collisions and collision craters due to collisions. Reasons for choosing Dimorphos: Dimorphous is an eclipsing variable system, making it an ideal system for test missions. The earth-based telescope can examine these brightness fluctuations to understand how long Dimorphos takes to orbit Didymos.
