Introducing the usage in planetary exploration as illumination of surface in robotic lunar exploration needs new testing techniques. Commercial LEDs are available in many packages, most SMD mounting and, in many cases, finished with a silicone glob top. The degradation caused by lunar regolith exposure onto all these options is unknown and shall be assessed by testing.

Under ESA contract number 20945/07/NL/IA, Alter Technology developed test benches for the characterization and qualification testing of 16bit (0.01º accuracy) Contactless angular sensors prototypes for telecom satellites’ extended life mechanisms. Angular sensors (AS) are position devices that provide the displacement in angular degrees concerning a fixed point or an arbitrary reference. The central performances to be measured are accuracy, hysteresis, and measuring range. These parameters must be measured before, during, and after applying environmental treatment during the qualification test campaign.

The Strain Gages are used to measure the deformation of materials. These devices are widely used when the deformation of a structure is relevant such as the wings of a plane or the structure of telescopes or rockets. The necessity of testing these strain gages at a wide temperature range leads to the necessity of coupling force-deformation equipment to climatic chambers.

The SuperCam is a next-generation scientific instrument that examines rocks and soils with a camera, laser, and spectrometers to seek organic compounds that could be related to past life on Mars. It can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (7 meters).

ALTER has participated in the REMS and MEDA projects to develop environmental stations working on Curiosity and Perseverance rovers. Part of NASA’s Mars Science Laboratory mission, within NASA’s Mars Exploration Program, Curiosity is the largest and most capable rover ever sent to Mars. This success case describes the methodology used to characterize the ultraviolet photodiodes used in the Curiosity rover.
