Spectroscopy is one of the most powerful tools in modern astronomy. By analyzing starlight, scientists can uncover a star’s composition, temperature, motion, and even the conditions of distant exoplanets. Until recently, such measurements required large observatories, but compact, high-performance instruments are changing that.
In preparation for the Mauve mission – a scientific satellite developed by Blue Sky Space – two Avantes NEXOS™ spectrometers will soon be launched into orbit to study the ultraviolet emissions of active stars. To validate their performance, an independent ground-based experiment was conducted using a Newtonian telescope and an unmodified NEXOS™ spectrometer, replicating space-like observations under terrestrial conditions.
Even under suburban skies, the NEXOS™ delivered high signal-to-noise spectra of the bright star Vega, confirming its precision, robustness, and suitability for space applications. These results were independently verified by the University College London Observatory (UCLO), demonstrating consistent, reproducible data across different environments.
In this white paper, we explore how the NEXOS™ bridges the gap between ground-based experimentation and orbital research, enabling reliable spectroscopy from the lab to the launchpad.
Inside you’ll find:
- Insights into the Mauve satellite mission and its scientific goals
- Details of the ground-based validation experiment using NEXOS™
- Spectral results and analysis of the star Vega
- A comparison with UCLO data, confirming cross-platform consistency
- How Avantes’ compact, robust design enables space-qualified spectroscopy
