Nasa expects that the orbit of Dimorphos around a larger asteroid – Didymos, which is 780 metres in diameter – will have shortened by about 1%, or roughly 10 minutes!
ATLAS observations of the DART spacecraft impact at DidymosLast night, Nicolas Erasmus (SAAO) and Amanda Sickafoose (@planetarysci) successfully observed DART's impact with Dimorphos using the Mookodi instrument on the SAAO's 1-m Lesedi telescope.@fallingstarIfA also did a very similar measurement using ATLAS-Sutherland.#DART #NASA pic.twitter.com/olr4gV5SOV
