Zond 6 and Zond 7
A souvenir sheet commemorating the flights of Zond 6 and Zond 7 around the Moon in 1968 and 1969. Both probes performed a ‘skip’ re-entry to reduce speeds. The trajectory shown on the sheet is actually that of Zond 7, which took pictures of the Earth and Moon. Examples of Zond 7’s photographs are shown in the form of two unperforated ‘stamps’ on the sheet. Zonds 6 and 7 were precursors for an intended manned flight that never happened.
