1. why did nasa crash the dart spacecraft into an asteroid, and what did they hope to achieve by doing this?

Explanation:

The DART (Double Asteroid Redirection Test) mission by NASA was a planetary defense test. NASA crashed the DART spacecraft into the asteroid Dimorphos (a moonlet of asteroid Didymos) to test the kinetic impactor technique. The goal was to see if intentionally crashing a spacecraft into an asteroid could change the asteroid’s orbital motion (specifically, the orbital period of Dimorphos around Didymos). This was a key step in developing a method to deflect potentially hazardous asteroids that might be on a collision course with Earth in the future, to protect our planet from asteroid impacts.

Answer:

NASA crashed the DART spacecraft into the asteroid Dimorphos (a moon of asteroid Didymos) as part of the Double Asteroid Redirection Test (DART) mission. The goal was to test the kinetic impactor technique—to see if deliberately crashing a spacecraft into an asteroid could alter the asteroid’s orbital motion (specifically, the orbital period of Dimorphos around Didymos). This experiment aimed to develop a method to deflect potentially hazardous asteroids from colliding with Earth, advancing planetary defense capabilities.
