Запуск - Ресурс-П №5 - Союз 2.1б - Федеральное космическое агентство России - Роскосмос

Launch - Resurs-P No.5 - Soyuz 2.1b - Russian Federal Space Agency - Roscosmos.
Site 31/6, Baikonur Cosmodrome, Kazakhstan.
Space Launch Scheduled:  Resurs-P No.5 - Soyuz 2.1b
Resurs-P is a series of Russian commercial Earth observation satellites capable of acquiring high-resolution imagery (resolution up to 1.0 m). The spacecraft is operated by Roscosmos as a replacement for the Resurs-DK No.1 satellite.
 
On Wednesday, Dec. 25, at 07:45:42 UTC, Russia successfully launched a Soyuz 2.1b rocket from Site 31/6 at the Baikonur Cosmodrome in Kazakhstan.

As described by Roscosmos, the payload consists of one satellite writing, “The Resurs-P spacecraft No. 5 is designed for high-precision, detailed wide-selective and hyperspectral optical-electronic observation of the Earth’s surface to study natural resources, control pollution, and environmental degradation, search for mineral deposits, assess the state of the ice situation, monitoring emergency situations, creating and updating topographic and navigation maps.”

The Soyuz 2.1b rocket used for this mission features decals describing it as the 2,000th R-7 rocket to be launched. The R-7 series was first built in 1957 as a missile but quickly became the workhorse of Soviet and Russian space missions.

The current Soyuz models are direct developments of the original R-7 model, with two major variants: the Soyuz 2.1a, which serves as a base version, and the Soyuz 2.1b, which utilizes a more powerful third stage. 

Soyuz 2.1b is powered by four RD-107A engines on the first stage (arranged around the second, core stage), a single RD-108A engine on the core stage, and an RD-0124 engine on the third stage. Each stage uses liquid oxygen and kerosene (RP-1) as propellants.
