This chapter concerns the final phase of Tunguska research after the collapse of the Soviet Union, while also looking back at the theories about the event developed by researchers abroad from the 1930s onward. It examines how international science about Tunguska developed from a dynamic of inadvertent corroboration, intentional collaboration, information lost in translation, and conjecture unmoored from Soviet thinking. Accordingly, international perspectives deepened the mystery as scholars from afar proposed their own array of solutions. The end of the Cold War allowed speculation to proliferate even more widely, while also enabling foreign specialists to visit the site for the first time. The past decades have also witnessed dramatic advances in the science of near-earth objects and a more broadly held conviction that an airburst explosion of a medium-sized asteroid fragment caused the Tunguska blast.
