Because of the position of Dimorphos in the sky at the time of impact, only telescopes in the red region shown here will be able to see it. This includes two contracted by ESA’s Near-Earth Object Coordination Centre: the 0.6 m Les Makes telescope on Réunion Island in the Indian Ocean and the 0.36 m Springbok telescope in Namibia.
In South Africa, the 0.5 m SMARTnet telescope, usually used to track space debris, will also be available to ESA, along with the 0.4 m Watcher telescope led by an Irish team. In Qatar, a team of advanced amateur astronomers is also lending time on their telescope to ESA and its network.
