DESCRIPTION:A Roscosmos Soyuz 2.1a rocket will launch two Aist-2T Earth ob
 servation satellites (designated Aist-2T №11L and Aist-2T №12L) into o
 rbit. Additionally on board are the first two satellites of the Sfera cons
 tellation\, Marafon-D №12L and Marafon-D №13L. Other payloads are Aist

 ong the 20 rideshare payloads are the Iranian Paya\, Zafar 2 and Toloo 3 s
 atellites. The mission was switched from Angara 1.2 to Soyuz. The rocket w
 ill fly in the Soyuz 2.1b configuration with a Fregat-M upper stage.\n-\nA
 ist-2T is a series of Russian earth observation microsatellites developed
  by TsSKB-Progress for obtaining stereo images of the Earth's surface\, wi
 th maximum resolution of 1.2 m in panchromatic mode and a swath width of 3
 2 km.\n-\nThe Russian Marafon-D satellites were built by ISS Reshetnev to 
 test the technologies for the operational Marafon constellation\, which wi
 ll be a low earth orbit constellation for internet of things (IoT) communi
 cations\, and is part of the Sfera program.\nSfera is a planned Russian co
 nstellation consisting of at least 162 satellites\, which would include co
 mmunication satellites Ekspress and Ekspress-RV in geostationary and high 
 elliptical orbits\, Skif satellites for broadband Internet access and Mara
 fon satellites. In addition\, the group will include Yamal communication s
 atellites\, Smotr remote sensing satellites and Berkut observation satelli
 tes.\n-\nDelayed from Q4 2022\, Q4 2023\, December 2024\, June 26\, July 3
 1\, late August and Oct. 20.
