Abstract NASA’s Double Asteroid Redirection Test (DART) mission tested planetary defence by altering an asteroid’s path, could offer a real-world context for integrating science into education. The objective is to design simulations based on the DART mission to merge scientific and school knowledge, enhance STEM education through experiential learning, and raise awareness of planetary defence. The requirements to reach the objective were set to reflect DART’s key phases—rendezvous and impact—considering 3D modelling, orbital timing, brightness, and adjustable start dates for varied mission scenarios. These classroom tools should allow students to manipulate time and observe orbital dynamics and photometric changes. The results include one simulation that models the spacecraft’s Keplerian motion to rendezvous with the Didymos asteroid, while the second shows the impact and its effect on the orbit. Students can explore planetary movement, analyse data, and evaluate different mission timelines. Bringing DART into the classroom bridges theory and application, strengthens STEM understanding and problem-solving, fosters engagement, and promotes awareness of planetary defence challenges.
