UV-Visible Spectrophotometry of Stars

Stellar Science

UV-Visible (200-700 nm)

Collaborative Programme

October 2025 Launch

Mauve is a UV-Visible satellite conceived to study stars in our galaxy, providing a greater understanding of their magnetic activity, powerful flares, and the impact on the habitability of neighbouring exoplanets. Data from the satellite will be delivered via a multi-year collaborative science programme, with thousands of hours each year available for long observations of hundreds of stars, unlocking a significant time domain astronomy opportunity.

Satellite

Mauve has been built in collaboration with leading satellite and instrument manufacturers C3S and ISISPACE. The high-heritage approach to the design and component selection will deliver a high-specification astronomy satellite within the short timeframes usually associated with commercial satellites. The satellite will operate in a low-Earth orbit, maximising opportunities for science observations along the ecliptic plane.

Science Programme

The scientific direction of Mauve is driven by its research community, and participating scientists shape the mission’s goals and observational strategies, ensuring the possibility for high-risk and high-reward science. Thousands of observational hours will be dedicated to each year of the programme, with many stars continuously available within Mauve’s wide field of regard, enabling long baseline observations and unlocking a significant time domain astronomy opportunity. Mauve’s wide field of regard covers the entire ecliptic plane and parts of the galactic plane, including the centre, and enables extended observation campaigns to support in-depth studies of stellar variability.

The programme will support a rich and diverse set of research themes, showcasing the mission’s wide potential and the creativity of our community. Regular data releases will be made to all members throughout the mission lifetime, with the Blue Skies Space team providing full-time support to assist in the provision and exploitation of the data.
