Zond 5

Zond 5The Soviet Union launches Zond 5, a Soyuz 7K-L1 command & service module intended for flight around the moon. Rather than a cosmonaut crew, however, Zond 5 has biological specimens on board, including insects, plants, bacteria, and a pair of turtles – the first living creatures from Earth to orbit the moon. The specimens are all returned safely, though Zond 5 is the second consecutive Zond flight to lose attitude control after re-entry, splashing down in the Indian Ocean rather than making the customary propulsive return to Soviet soil. American intelligence agencies are aware of the mostly successful flight, and NASA alters the Apollo manned flight schedule to attempt to put men in orbit of the moon by the end of 1968.
