Note: Payload identity and Cosmos series numbering not confirmed. The Strela (Russian: Стрела) are Soviet, then Russian, military space telecommunication satellites, in use since 1964. These satellites operate as mailboxes ("store-and-forward"): they remember the received messages and then resend them after the scheduled time, or by a command from the Earth. They can serve for up to five years. The satellites are used for transmission of encrypted messages and images. The operational constellation consists of 12 satellites in two orbital planes, spaced 90° apart. The spacecraft had a cylindrical body with a gravity-gradient boom, which was extended on-orbit to provide passive attitude stabilization. On-board storage was 12 Mbits of data, with a transmission rate of 2.4 kbit/s. The first three satellites were launched in 1964 by a Cosmos launcher. After one year of service, new and improved satellites were launched, called Strela-2. In 1970, these satellites were modernized, and became the Strela-1M and Strela-2M satellites. From 1985, these satellites will be gradually replaced by Strela-3, and then by Strela-3M from 2005. A civilian version of these satellites was created, called Goniets. Initially they were launched in groups of six on Tsyklon; when the launcher was retired, they were only launched by two on Cosmos, before Rokot was put into service and allowed the sending of triplets of Strela satellites.
Low Earth OrbitSPHEREx is a planned two-year astrophysics mission to survey the sky in the near-infrared light, which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions involving the birth of the universe, and the subsequent development of galaxies. It also will search for water and organic molecules – essentials for life as we know it – in regions where stars are born from gas and dust, known as stellar nurseries, as well as disks around stars where new planets could be forming. Astronomers will use the mission to gather data on more than 300 million galaxies, as well as more than 100 million stars in our own Milky Way galaxy. NASA’s Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will share a ride to space with SPHEREx. It consists of four suitcase-sized satellites, which will focus on the Sun’s outer atmosphere (the corona) and how it generates the solar wind. The spacecraft also will track coronal mass ejections – large eruptions of solar material that can drive large space weather events near Earth – to better understand their evolution and develop new techniques for predicting such eruptions.
Sun-Synchronous Orbit B1088 - Flight Proven ( ) Landing Zone 418 Low Earth Orbit communication satellites with Ku, Q and V band payloads for the G60 constellation operated by Shanghai Spacecom Satellite Technology (SSST) with funding backed by the Shanghai local government. Initial constellation will consist of 1296 satellites by 2027 with long term plans to expand it to 12000 satellites. First launch from the Wenchang Commercial Space Launch Site's LC-1.
