Russia launches animals into space: Here’s the purpose behind the mission
Russia is set to launch Bion-M No. 2 biosatellite on August 20, 2025, from Baikonur Cosmodrome, will carry fruit flies, mice, plant seeds, microorganisms, and lunar simulants for a 30-day space mission. The project focuses on studying the effects ...

Building on this history, Russia is preparing to launch the Bion-M No. 2 biosatellite on August 20, 2025, using a Soyuz-2.1b rocket from the Baikonur Cosmodrome in Kazakhstan. Often referred to as a modern “Noah’s Ark,” this mission will carry 75 mice, more than 1,000 fruit flies, plant seeds, cell cultures, and microorganisms for a 30-day orbital experiment. The main focus is to examine how prolonged exposure to microgravity and cosmic radiation impacts living organisms, providing important information for future human spaceflight.
Innovations Compared to Earlier Missions
Following the precedent set by the 2013 Bion-M No. 1 mission, Bion-M No. 2 will follow in a polar orbit inclined at roughly 97 degrees. This flight path exposes the biosatellite to far higher stages of cosmic radiation estimated to be at least ten times more than the earlier mission. These conditions better replicate the environment astronauts face during extended deep-space missions, enabling for more accurate information on the biological effects of space travel.Mice: A Core Focus for Space Medicine
Mice play a critical role in the mission due to their genetic resemblance to humans, short lifespans, and heightened sensitivity to radiation. The animals will be organized into three groups: one kept on Earth under normal conditions, a second in a ground-based simulator replicating spacecraft conditions, and a third sent into orbit. This arrangement enables scientists to compare how spaceflight changes biological systems compared to Earth-based controls.Each habitat is equipped with feeding systems, lighting, ventilation, and waste disposal. Sensors and cameras will monitor the mice constantly , and some will carry implanted devices to record physiological changes during the mission. After returning to Earth, researchers will analyze how they adapted to space conditions and how they readjusted to gravity.
Fruit Flies and Other Experimental Subjects
Alongside the mice, over 1,000 fruit flies will also travel on the mission. . Their extensively studied biology and quick generational cycles, provide valuable insights into radiation that influence at the genetic and cellular levels. Plant seeds and cell cultures aboard the biosatellite will further inform researchers about how microgravity affects growth and cellular processes.Collectively, these experiments offer a holistic view of life’s response to the conditions of space.Lunar Simulants: Exploring Moon-Like Conditions
In a unique addition, the mission will include 16 test tubes of lunar simulants materials made to replicate Moon dust and rocks. Conducted in collaboration with the Vernadsky Institute of Geochemistry and Analytical Chemistry and the Institute of Medical and Biological Problems, focus to observe how lunar-like substances communicate with biological systems in orbit. The insights could guide future lunar exploration and shed light on potential effects on living organisms.FAQs:
