No one would dispute that 1985 and 1986 were unique times for cometary research. In September 1985 ISEE-3 transited the magnetotail of comet Giacobini-Zinner and provided the first close-up scientific view of a cometary environment. Half a year later an international fleet of spacecraft equipped with state-of-the-art instrumentation gave us a “once-in-a-lifetime” look at comet Halley.
