Bion 11 was a Russian space mission that was part of the Bion series of space flights. Scientists from France, Russia and United States conducted the experiments.


It carried newts, snails, Drosophila flies and other insects, bacteria, and two macaque monkeys (Macaca mulatta), Lapik and Multik. Both monkeys were safe at landing but Multik died of a heart attack during medical tests under general anaesthetic on 8 January 1997.

The Magee-8 scientific equipment was designed to study the basic features of electrostatic modular protection system. Other equipment was used to maintain the temperature and humidity within the specified range, the atmospheric regeneration, physiological parameters of the monkeys were recorded and transferred them to the ground in TV picture.

A similar mission "Bion-12" was scheduled for December 1998 but did not take place due to cessation of participation of the United States.
