Ariane 5 ECA+ | James Webb Space Telescope (JWST)
ArianeGroup | FRAKourou, French Guiana
Dec. 25, 2021, 12:20 p.m.
Status: Launch Successful
Mission:
The 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.

Oct. 24, 2021, 2:10 a.m.
Status: Launch Successful
Mission:
SES-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 OrbitAriane 5 ECA+ | Star One D2 & Eutelsat Quantum
ArianeGroup | FRAKourou, French Guiana
July 30, 2021, 9 p.m.
Status: Launch Successful
Mission:
Star 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 VA254Ariane 5 ECA+ | Galaxy 30, MEV-2 & BSAT-4B
ArianeGroup | FRAKourou, French Guiana
Aug. 15, 2020, 10:04 p.m.
Status: Launch Successful
Mission:
Galaxy-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.
Geostationary Transfer OrbitAriane 5 ECA+ | JCSAT-17 & GEO-KOMPSAT-2B
ArianeGroup | FRAKourou, French Guiana
Feb. 18, 2020, 10:18 p.m.
Status: Launch Successful
Mission:
JCSAT-17 is a Japanese communication satellite of SKY Perfect JSAT Corporation. Its payloads incorporate S-band, C-band and Ku-band transponders, which will provide satellite communication services. The S-band and C-band transponders will serve NTT DOCOMO, Inc., the largest telecommunications company in Japan, for its flexible mobile communications services in Japan and the surrounding region under IRU contract (Indefeasible Right of Use). SKY Perfect JSAT will support NTT DOCOMO’s satellite communication services. JCSAT-17 also includes a flexible processor that will allow SJC to redirect capacity to concentrate on disaster relief efforts or other high-volume events. The GEO-KOMPSAT-2 program is a national program of the Korean government to develop and operate two civilian geostationary satellites sharing the same satellite bus: GEO-KOMPSAT-2A for meteorological and space weather monitoring missions; and GEO-KOMPSAT-2B for Earth environment monitoring and ocean monitoring missions. The GEO-KOMPSAT 2 program also ensures the succession for the COMS program (Communication, Ocean and Meteorological Satellite). The satellite carries two main payloads: GOCI II (Geostationary Ocean Color Imager II), provided by Airbus Defence and Space; and the GEMS (Geostationary Environment Monitoring Spectrometer), provided by Ball Aerospace & Technologies.
