A new report recommends “immediate, well-funded, comprehensive, and collaborative work” to implement a series of measures to mitigate the negative impacts that large satellite constellations on ground-based astronomy.

The report, whose executive summary was published last week, includes 10 recommendations for observatories and constellation operators that include the development of software to identify and mask satellite trails and designs changes to lessen the reflectivity of satellites. (The full list of recommendations are below.)
