Syracuse 4B is a French military communications satellite built by Thales Alenia Space. Heinrich Hertz (H2Sat) is a small geostationary communications satellite built by OHB System and the German Aerospace Center (DLR) to explore and test new broadband communications technologies.
Geostationary Transfer OrbitThe James Webb Space Telescope is a space telescope developed by NASA, ESA and CSA to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission. Its primary mirror, the Optical Telescope Element, is composed of 18 hexagonal mirror segments which combine to create a 6.5 m diameter mirror, considerably larger than Hubble's 2.4 m mirror. This will allow JWST to provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies.
Sun-Earth L2SES-17 is a Ka-band high-throughput geostationary communications satellite built by Thales Alenia Space designed to provide mobile internet services to airline passengers over the Americas and the Atlantic Ocean. Syracuse 4A is a French military communications satellite built by Thales Alenia Space.
Geostationary Transfer OrbitStar One D2 is a 6.2 tons satellite built by Space Systems Loral for operator Star One, subsidiary of Brazilian Embratel. Its architecture is based on a SSL-1300 platform and equipped with C, X, Ku and Ka-band transceivers. It will provide communications services to Latin America for at least 15 years. Eutelsat Quantum is an experimental communications satellite carrying a payload able to be reconfigured by software. It is developed by ESA, Eutelsat and Airbus Defence and Space.
Geostationary Transfer Orbit VA254Galaxy-30 is a geostationary communications satellite for Intelsat. Satellite is built by Northrop Grumman Innovation Systems (NGIS) and is planned to provide video distribution and broadcast services to customers in North America. Galaxy 30 satellite is launched in tandem with MEV-2 vehicle. MEV-2, which stands for Mission Extension Vehicle-2, is the second servicing mission by NGIS. MEV-2 will rendezvous and dock with the Intelsat 1002 satellite in early 2021. Then, MEV-2 will use its own thrusters and fuel supply to control the satellite’s orbit, thereby extending its useful lifetime. Another passenger of the flight is the BSAT-4b satellite for the Japanese operator BSAT. BSAT-4b will serve as a back-up for BSAT-4a satellite, launched in 2017. BSAT-4b will provide Direct-to-Home television services and is expected to operate for at least 15 years.
