Provide Hands-on Activities

DART AR Experience

Explore and manipulate the DART spacecraft on your computer screen or access an augmented reality (AR) version of the spacecraft on your cell phone. It’s the perfect way to virtually experience the DART spacecraft from any location.

DART 3D Printable Spacecraft Model

What better way to explore the DART spacecraft than by having your own 3D-printed model? With these downloadable files, you can print the body of the spacecraft and its solar arrays.

DART 3D Printable Asteroid Model

You can explore the double-asteroid system that is the target of the DART mission with your own 3D-printed model. With these downloadable files, you can print the larger asteroid, Didymos, the smaller asteroid, Dimorphos, and the pieces needed to build a stand that allows Dimorphos to orbit around Didymos.

DART Toy Bricks Model

Enjoy this 1/12-scale model of the DART spacecraft made out of toy bricks! At this scale, the solar arrays are too large to build out of toy bricks–so the student team that designed the model created solar arrays that can be printed on paper, card stock or foam board, and attached to the body of the toy brick DART.

Eyes on Asteroids

With NASA’s Eyes on Asteroids, you can watch all the known near-Earth asteroids and comets as they orbit the Sun. Updated twice daily with the latest tracking data, the web-based application will automatically add new near-Earth object discoveries for you to explore.Don’t forget to do a search for the DART spacecraft trajectory!
