And S/C Sep. Mice in space! They will be returned for a landing, but some will be rewarded for their space exploits by being dissected

Why was it revised? To be compatible with the upcoming Russian orbital station?

Yes, after the decision was made to withdraw from the ISS program and build ROS instead.

Can someone upload the PDF version of the press kit?

Thank you. Seems the problem was not-updated information

There seems some confusion about the orbit. Most sources mentioned it to be 800-1000 km. A few say 370-380 km. Why that difference in some sources?
As far as I understand, the planned orbit was revised in 2022. Before this, it was 800x800/51.6°. Hence the confusion (even in Wikipedia, some media outlets probably get their data from there).

I made a PDF from the Telegram link.

All science-related information from this point forward needs to be posted in this dedicated thread.

And launch-related information can continue in this thread.

"This week, on September 19, we expect the descent module to land."

Perigee has been lowered to 146 km a few days ago. So yes, it's coming back.

No space force TLEs since Sep 12 (indeed the last one showing it in a 147 x 486 km orbit).
Perhaps it already landed?

New TLE from today show Bion-M at 264x279 km @ 96,92°. So, the previous data from September 12th may have been erroneous (inclination @95,5°).

Bion-M No.2 landed.

Satori · « **Reply #77 on:** 09/19/2025 08:01 am »

From Roscosmos Telegram...

The descent module of the Bion-M No. 2 biological satellite has landed.

The spacecraft was launched from Baikonur on August 20th; 30 days later, it returned to Earth with living organisms on board.

▶️ After landing, they will be sent to Moscow for further research.
