Bion-M No.2 (Бион-М) is a Russian space mission, part of the Bion programme focused on space medicine. The new generation Bion-M continues the Soviet/Russian satellite programme aimed at biological research in space. The most recent spacecraft of the series, Bion-M No.1, was launched in 2013. The Bion-M spacecraft is designed to carry biological, physiological and biotechnological experiments to low Earth orbit and return them to Earth at the end of the mission.
The satellite has components from two long-standing Soviet spy satellite families. Bion's landing unit is from the Zenit 2M satellite and the satellite also carries an instrument section developed for the Yantar satellite. The satellite was made by TsSKB Progress of Samara, Russia.
