Bion-M with TUS satellite attached

Bion-M is the next generation of russian biological research satellites. While retaining the Vostok/Zenit-derived reentry module of the earlier Bion, the propulsion module has been replace by a Yantar type module, which provides maneuvering capabilities and longer mission support. The mission duration has been increased to up to 6 months by using solar cells for energy generation. The weight of scientific equipment has been increased by 100 kilograms.

A first mission is scheduled for 2012, while one more is planned to launch three years later.
