There is growing concern that collision risk in low Earth orbit is inadequately managed, necessitating new strategies. Based on discussions held at a multistakeholder workshop organized by EPFL in May 2021, this paper presents some challenges, or governanc ...
Wide-field imaging surveys such as the Dark Energy Survey (DES) rely on coarse measurements of spectral energy distributions in a few filters to estimate the redshift distribution of source galaxies. In this regime, sample variance, shot noise, and selecti ...
This IRGC policy brief focuses on the risk of collision from space debris. It provides a range of policy options and broad recommendations to improve the assessment, evaluation and management of collision risk, as well as its communication. It is based on ...
As the pace of space activities accelerates and societies become more reliant on space-based systems, the associated risks deserve more attention. Satellites form a critical infrastructure on which military, civil and commercial entities rely. The services ...
