Two 🇷🇺 Russian space weather satellites are on their way to orbit, along with an 🇮🇷 Iranian spacecraft and a passel of cubesats.
A Soyuz 2.1b rocket lifted off from Vostochny Cosmodrome in Siberia today, July 25 at 8:54 a.m Moscow time, carrying Russia's Ionosfera-M 3 and 4 satellites toward Earth orbit. The Soyuz also carried 18 secondary payloads, according to RussianSpaceWeb.com, including an Iranian communications satellite called Nahid-2.
Everything went well in the early stages of the launch, which the Russian space agency Roscosmos streamed live. The webcast ended about 10 minutes after launch, however, news of satellite deployments will have to come via updates from the agency.
The first two Ionosfera-M satellites launched from Vostochny in November 2024. Spacecraft 3 and 4 will round out the mini constellation, which flies about 509 miles (820 kilometers) above Earth.
"The quartet is designed to monitor space weather phenomena, such as the impact of solar wind on the near-Earth space affecting civilian and military systems," RussianSpaceWeb wrote.
As their name suggests, the Ionosfera satellites focus on the ionosphere, a layer of Earth's atmosphere that ranges from about 50 to 400 miles (80 to 645 km) in altitude. The ionosphere interacts strongly with the sun, which explains the layer's name: its atoms and molecules are ionized (have had electrons stripped away) by solar radiation.
Ionosfera-M 3 and 4 are headed for an orbital plane perpendicular to that of their two brethren, "thus greatly expanding the three-dimensional coverage of the Earth's magnetosphere," according to RussianSpaceWeb.
"The second pair would also include for the first time the Ozonometr-TM instrument for measuring levels of ozone in the upper atmosphere."
