MOSCOW (Sputnik) - Russia will begin preparations for the launch of Bion-M No. 3 research satellite in 2026, Russian state space corporation Roscosmos said on Sunday.
"Preparations for the launch of Bion‑M No. 3 will begin in 2026. The purpose of the launch is to study the factors of a spaceflight in conditions of more severe radiation exposure," Roscosmos said on Telegram.
Bion‑M No. 3 will be placed into a higher orbit than that of its predecessor, Bion-M No. 2, with an altitude of about 800 kilometers (497 miles) and with the same inclination of about 97 degrees, Roscosmos added.
Bion-M No. 2 carried 75 mice and 1,500 drosophila flies to the orbit in August to test the biological effects of space environment at a high-latitude orbit, as it has more cosmic radiation and other geomagnetic conditions than traditional orbits with an inclination of 50-60 degrees.
