Part 8/11:
This system must compensate for the lack of detailed shape information and the dark, often obscured surfaces of the asteroid—challenges overcome through extensive simulation and testing. When just two minutes from impact, the spacecraft will have a clear view of Didymos B and will maneuver to hit the target’s center as accurately as possible.
Technical Innovations Demonstrated
DART isn’t just about asteroid deflection. It also serves as a technology testbed for future planetary defense endeavors. The mission demonstrates cutting-edge systems:
NEXT-C Ion Engine: Providing efficient propulsion.
Roll-Out Solar Arrays: Lightweight, effective power sources.
