I'm saddened to have just heard the news that Svetlana Gerasimenko passed away last week, on 8 April.
She was the co-discoverer in 1969 of Comet 67P/Churyumov-Gerasimenko with fellow Ukrainian astronomer, Klim Churyumov (1937-2016).
This is the comet that was explored by ESA's Rosetta spacecraft from 2014-2016 & landed on by the Philae probe in November 2014.
A comet & events that changed my life 🙇♂️
Ad astra, Svetlana ✨
