ESA’s Hera Mission Launches and LEGO Tribute
The European Space Agency’s (ESA) Hera mission, which aims to defend Earth against potential asteroid impacts, successfully launched last October and recently completed a flyby of Mars. As a memorable tribute to the mission, the Hera team commissioned a detailed LEGO model of the spacecraft, designed by astronomer Frans Snik, known for creating intricate models of astronomical observatories.
Frans Snik crafted a 1:11 scale model of the Hera spacecraft and its accompanying CubeSats, Milani and Juventas, using 4,448 LEGO bricks. This model made its public debut during the ESA Open Day at ESTEC in the Netherlands, just before the spacecraft’s launch. Recognizing the complexity of the model, Snik also designed simplified, cartoon-style versions of the models to make them more accessible for builders.
These cartoon models are part of the “Incredible Adventures of the Hera Mission” animation series, which follows the spacecraft and its journeys. Snik’s work captures additional whimsical touches, including interactive features like arms that wave to greet Hera during its mission.
Frans expressed excitement about the engineering capabilities of the Hera spacecraft and made it his goal to recreate its intricate details in the LEGO models. The animations of Hera’s journey have further inspired his designs, as he incorporated many of these elements into the models.
Additionally, Paolo Concari, an engineer on the Hera project, took the initiative to develop another LEGO model in his spare time. Inspired by an online creation that he believed lacked accuracy, Concari utilized a 3D modeling tool called STUDIO 2.0 to create a more precise version. His model, consisting of 98 pieces, is a scaled-down representation of the Hera spacecraft and its characteristics.
The process proved to be a valuable learning experience for Concari as he faced challenges in crafting assembly instructions and utilizing design software. Notably, Concari incorporated creative solutions, such as using mini binoculars as thrusters on his model.
Concari engaged his children in the testing phase of his model, gaining crucial feedback that helped refine the instructions. The final product serves not only as a fun project but also as a practical tool for the Hera mission team to visualize the spacecraft’s maneuvers.
By studying the Dimorphos asteroid, which had its orbit altered by NASA’s DART spacecraft in a historic impact, the Hera mission aims to gather critical data that may lead to effective asteroid deflection methods. This project underscores the importance of planetary defense as a growing area of exploration and concern for humankind.
For those interested in building these models, assembly instructions and needed LEGO parts are available online, allowing enthusiasts to connect with the mission creatively.
