Upcoming Spaceflights
Soyuz 2.1a | Bion-M No. 2
Progress Rocket Space Center | RussiaBaikonur Cosmodrome, Republic of Kazakhstan
Aug. 20, 2025, 5:13 p.m.
Status: Go for Launch
Mission:
Bion-M is the next generation of Russian biological research satellites. While retaining the Vostok/Zenit-derived reentry module of the earlier Bion, the propulsion module has been replace by a Yantar type module, which provides maneuvering capabilities and longer mission support. The mission duration has been increased to up to 6 months by using solar cells for energy generation. The weight of scientific equipment has been increased by 100 kilograms.

Mission:
The Russian Obzor-R satellite is a planned X-band radar earth observation satellite designed by TsSKB-Progress. In 2012, the development of the Arkon-2M radar satellite was stopped and instead the development of the Obzor-R was initiated. The satellite features the BRLK X-band Synthetic Aperture Radar as the imaging instrument with a ground resolution of 500 m.

Note: Payload identity uncertain. Bars-M is the second incarnation of the Bars project, which was started in the mid 1990ies to develop a successor for the Komtea class of area surveillance satellites. The original Bars project was halted in the early 2000s. In 2007, TsSKB-Progress was contracted for Bars-M, for which reportedly the Yantar-based service module was replaced by a new developed advanced service module. The Bars-M satellites feature an electro-optical camera system called Karat, which is developed and built by the Leningrad Optical Mechanical Association (LOMO), and a dual laser altimeter instrument to deliver topographic imagery, stereo images, altimeter data and high-resolution images with a ground resolution around 1 meter.
