  • We used the UltraViolet-Optical Telescope on board Swift to systematically follow the dynamically new comet C/2013 A1 (Siding Spring) on its approach to the Sun. The comet was observed from a heliocentric distance of 4.5 AU pre-perihelion to its perihelion at 1.4 AU. From our observations, we estimate that the water production rate during closest approach to Mars was 1.5 ± 0.3 × 1028 molecules s−1, that peak gas delivery rates where between 4.5 and 8.8 kg s−1, and that in total between 3.1 and… CONTINUE READING
