In an exciting collaboration with NASA, Photonis, a forefront innovator in high-end electro-optical technologies, has played a crucial role in a mission geared towards demystifying the Aurora Borealis phenomenon. Known for its stunning natural light displays in the Earth’s polar regions, the Aurora Borealis, or Northern Lights, has long fascinated scientists and spectators alike. However, the recent NASA mission, named DISSIPATION, delved deeper than mere admiration. Launched from the Poker Flats Research Range in Fairbanks, Alaska, on November 8, the mission sought to unravel the intricacies of energy dissipation from solar winds into the Earth’s atmosphere, a process intimately linked with the formation of auroras.

Taking off in the wee hours to align with the peak activity of the aurora, the DISSIPATION mission embarked on its journey aboard a suborbital two-stage sounding rocket. Central to its payload was NASA’s MoSAIC (Modular Spectrometer for Atmosphere and Ionization Characterization) instrument, which was significantly enhanced by Photonis’ cutting-edge Channeltron® Channel Electron Multipliers. These detectors are renowned for their precision in measuring various atmospheric parameters, such as the composition, density, temperature, and velocity of neutral and ion winds in the upper atmosphere. The inclusion of Photonis’ technology underscores the collaboration’s potential to advance our understanding of space weather and aurora mechanics.

The significance of this mission lies not only in its potential to enrich scientific understanding but also in its implications for space weather predictions. Solar winds and their interaction with the Earth’s magnetic field play a pivotal role in the formation of auroras. By examining the process of energy dissipation within this context, scientists hope to gather insights that could lead to more accurate models of space weather phenomena. Such advancements hold importance for a variety of reasons, ranging from satellite operation to communication systems, which can be adversely affected by severe space weather events.

Ulrich Laupper, President and Executive General Manager of the Exosens Ultimate Detection Business Unit, expressed excitement and honour at Photonis’ involvement in the mission. He highlighted the importance of this collaboration for unlocking the mysteries of the universe and advancing scientific knowledge for the betterment of society.

Photonis, operating under the umbrella of Exosens, brings to the table over 85 years of expertise in developing technologies critical for the detection and amplification of ions, electrons, and photons. Its products find extensive applications across diverse fields, including Defense & Security, Nuclear Safety, Life Science, and Industrial & Non-Destructive testing. The company’s contribution to the DISSIPATION mission represents another feather in its cap, demonstrating its role as a major player in the scientific community’s efforts to explore and understand our universe more profoundly.

While the full analysis of data from the mission will take some time, initial reports suggest that the DISSIPATION mission has been a resounding success. This promising start paves the way for further discoveries about the Aurora Borealis and its underlying processes, promising exciting advancements in the field of space weather predictions.
