Question

1. why was dimorphos chosen as the target for the dart mission?

a. it was a safe asteroid to test on because it wasnt headed toward earth.
b. it was on a collision course with earth.
c. it contained valuable minerals that nasa wanted to study.
d. it was the largest asteroid in the solar system.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: The DART mission aimed to test asteroid deflection technology. Dimorphos was a binary asteroid (with Didymos) not on a collision course with Earth, making it a safe target for testing without risking Earth.
• Option B: Dimorphos (and Didymos) were not on a collision course with Earth, so this is incorrect.
• Option C: The DART mission was about deflection, not mineral study, so this is irrelevant.
• Option D: Dimorphos is not the largest asteroid in the solar system (e.g., Ceres is much larger), so this is false.

Answer:

A. It was a safe asteroid to test on because it wasn't headed toward Earth.
