| Now that 3D printing seems to be an unexpected tool for NASA, detailed scale models of planets such as comets, asteroids and other worlds are being used to help test spacecraft navigation and landing systems in real life.  The structure of the model is based on data and images of early space missions. The image above shows two versions of the Mars moon Phobos model. The white in the background is the original 3D printed object. Explained by Olivier Dubois Matra, Director, Navigation, and Control Section, European Space Agency Say: 'We then add colors and finishes to create a more realistic model in the foreground.' The moving camera is then used to represent the spacecraft's view of the Earth and manipulate it around the model This allows physical testing of the guidance and landing procedures and for use with virtual tests using specialized software. |
