Roscosmos launched the Soyuz MS-21 mission to the ISS this Friday at 15:55 UTC. Following spacecraft separation, the Soyuz Capsule docked with the ISS’s Prichal module around three hours later to begin a six-month mission.
Launch Date: March 18, 15:55 UTC
Payload: Soyuz MS spacecraft carrying three Cosmonauts
Rocket: Soyuz 2.1a
Launch Pad: Site 31/6, Baikonur Cosmodrome, Kazakhstan
Destination: International Space Station (Low Earth Orbit)
A Soyuz 2.1a rocket and Soyuz MS spacecraft will launch an all Russian-crew to the International Space Station. Cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov will enjoy a six-month stint aboard the orbiting laboratory conducting science experiments, amongst other work.
What is Soyuz 2.1a?
Soyuz 2.1a is a three-stage, medium-lift rocket standing 46.3m tall. The rocket is Russia’s workhorse in delivering cargo and crewed spacecraft to the ISS several times a year.
Its first stage consists of four side boosters, each sporting one RD-107A engine, whilst its center core is propelled by a single RD-108A engine. The third stage of the Soyuz 2.1a rocket is then powered by an RD-0110 engine to deliver the Soyuz MS spacecraft to a safe orbit.
Adopting the Kurs-NA automatic docking system, the three-person Soyuz spacecraft consists of an orbital, descent, and service module to deliver the vehicle to and from the ISS and Earth.
