On September 19 local time, the Russian bioscience experimental satellite "Bion-M" 2 successfully landed in the Russian state of Orenburg.

The satellite, carrying 75 mice and about 1,500 fruit flies, as well as samples of plants, fungi, and others, was launched on August 20 from the Baikonur space launch site in Kazakhstan.Return to Earth with living organisms after 30 days in orbit¡£ The carried organisms will be sent to Moscow for follow-up research.

According to Russian media reports, the "Bion-M" 2 biological satellite was sent into a high-latitude orbit between 370 and 380 kilometers from the surface of the earth, the orbit of the cosmic radiation level is about one-third higher than the International Space Station orbit, and there are differences in geomagnetic environment. scientists hope to use this to study the biological safety of the orbit, laying the foundation for related manned space flights.

The "Bion" series satellites are spacecraft independently developed by Russia for biological research. In 2013, the first satellite of the "Bion-M" series was successfully launched, sending mice, gerbils, geckos, snails and plants into space. (Headquarters reporter Hao Wei)
