ESA’s Director of Science visits cosine

On 29 May 2024, cosine welcomed a delegation from the European Space Agency (ESA), including Dr Carole Mundell, the Director of Science, Dr Frederic Safa, Head of Future Missions, and Dr Marcos Bavdaz, Head of the Technology Preparation Section SCI-FT, to its headquarters in Sassenheim, The Netherlands.

The visit included a guided tour of cosine’s new headquarters in Sassenheim, which includes 1,300 m2 of ISO 7 to ISO 5 cleanrooms and sophisticated assembly facilities, dedicated to building and testing systems for space and industrial clients. Within these facilities, cosine’s staff demonstrated the equipment that is being used for developing the production process for the X-ray optics mirror modules for ESA’s upcoming large X-ray telescope, NewAthena. The tour included a visit to cleanrooms dedicated to producing innovative remote sensing solutions.

SPO for NewAthena
The goal of the visit was to explore and discuss cosine’s contribution to NewAthena. For two decades ESA, cosine and its partners have together been developing the Silicon Pore Optics (SPO) technology, to be able to build a 2.5 m diameter X-ray lens using hundreds of mirror modules. With a projected launch date in the 2030s, NewAthena (Advanced Telescope for High-ENergy Astrophysics) will be the largest X-ray telescope flown to date, equipped with state-of-the-art scientific instruments. It is designed to address key questions in astrophysics as part of the Cosmic Vision science program “The Hot and Energetic Universe.” The SPO technology will enable unprecedented observations of black holes, galaxy clusters, and dynamic processes in the Universe.

The Managing Directors of cosine, Max Collon and Prof. Dr Marco Beijersbergen, provided detailed insights into the innovative work being done for NewAthena, including the history and current status of the ongoing work.

We were honored to receive this delegation at our headquarters and look forward to our continued collaboration.
