Answer 1

The Correct Option is D

Concept: Planetary defense systems represent a major collaborative and technological frontier in modern aerospace engineering. The primary focus of these initiatives is to evaluate dynamic methodologies for altering the orbital trajectory of near-Earth objects (NEOs) such as comets or asteroids. This is achieved by utilizing kinetic impactor mechanisms, which help prevent catastrophic impacts with Earth.

Step 1: Review the core parameters of the Double Asteroid Redirection Test (DART) mission. The mission was designed to test whether a spacecraft could navigate to a binary asteroid system and deliberately collide with a target moonlet to alter its orbital speed through kinetic momentum transfer.

Step 2: Identify the executing space agency. The project was conceptualized, funded, and executed under the leadership of the National Aeronautics and Space Administration (NASA) in the United States, alongside key research implementations provided by the Johns Hopkins Applied Physics Laboratory (APL).

Step 3: Evaluate the target system. The spacecraft targeted the binary near-Earth asteroid system consisting of Didymos and its smaller companion moonlet, Dimorphos. The successful impact shortened the orbital period of Dimorphos around Didymos, proving the viability of kinetic deflection. While subsequent international follow-up missions, such as the European Space Agency's Hera mission, are scheduled to perform detailed post-impact surveys of the crater and mass changes, the core DART architecture belongs entirely to NASA. Therefore, Option (D) is the correct choice.
