Almaty, the ex-capital of Kazakhstan and a contender for hosting of the 2022 Winter Olympics, is often called the "southern capital of Kazakhstan". In an institute here, in 1969, Klim Ivanovic _________ and Svetlana Ivanovna __________ had developed few photographic plates. One of these plates seemed to be under-developed, with a tiny splotch of light in the centre. Considering it defective, Svetlana was about to discard the plate, when she thought against it and kept it back with all the plates. The fact of Svetlana not having discarded the plate, has proved effective.
How has it proved effective? OR give the surnames of the two.

=> The surnames are Churyumov and Gerasimenko, in reference to the blanks - the comet 67P/Churyumov–Gerasimenko is named after the two. Although the two astronomers were initially researching on comet 32P/Comas Solà, when they returned to Kiev, after calculations, the splotch on the "defective" plate turned out be a new comet altogether - the 67P comet. Recently, for the first time in history, the Philae probe of the Rosetta Orbiter mission has landed on the comet.
