Lander manager provides update on Philae status

Comet C/2023 P1 (Nishimura) is a brand new comet discovered by on August 11 by Hideo Nishimura of Japan. In its one and only visit to the Solar System, it may reach magnitude +2 when at perihelion in September.

Research teams across Europe spent the last half-year meticulously going through a wish list of experiments for the Philae comet lander without knowing whether they would ever get a chance to execute the tasks.

ESA’s Rosetta spacecraft has witnessed 67P/Churyumov–Gerasimenko make its closest approach to the Sun (perihelion) at 3:03am BST on 13 August, when the comet came within 116 million miles of our nearest star. Rosetta’s measurements suggest the comet is currently spewing up to 300kg of water vapour and a metric tonne of dust every second, creating dangerous working conditions for the spacecraft.
