What is the DART Mission?

About DART Mission

• NASA’s DART mission was a spacecraft designed to test a method of deflecting an asteroid for planetary defense, using the “kinetic impactor” technique (in simplest terms means smashing a thing into another thing).
• DART was the first-ever space mission to demonstrate asteroid deflection by kinetic impactor.
• The target of the spacecraft was a 160-meter-wide asteroid known as Dimorphos, which is a moonlet in orbit around the larger asteroid, Didymos.
• It was launched in November 2021.
• DART spacecraft successfully collided with Dimorphos on 26 September 2022, altering the asteroid’s orbit by 33 minutes.
• It is the first time humanity intentionally changed the motion of a celestial object in space.

What are Boulders?

• It is a geological term for a rock fragment that is larger than 25.6 centimeters (10.1 inches) in diameter.
• Boulders can be made up of various types of rocks, including igneous, sedimentary, and metamorphic rocks.
• The composition of a boulder depends on the geology of the area in which it formed.
