Abstract ASTRAL is a project to create high‐resolution, high‐S/N UV (1150–3200 Å) atlases of bright stars utilizing HST/STIS. During Cycle 18 (2010–2011), eight cool star targets were observed, including key objects like Procyon and Betelgeuse, churning through 146 orbits in the process. The new spectral atlases are publically available through the project website. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
