Soyuz MS-03 begins expedition 50 by carrying NASA astronaut Peggy Whitson, ESA astronaut Thomas Pesquet and Roscosmos cosmonaut Oleg Novitskiy to the International Space Station. After launching from the Baikonur Cosmodrome in Kazakhstan, they will rendezvous to the station where they will remain for their 6 month stay.
Low Earth OrbitThe Galileo constellation is ESA's satellite navigation system and is expected to be completed by 2020. Galileo will provide Europe with an alternative to the American GPS and Russian GLONASS constellations, but will be interoperable with both systems.
Medium Earth OrbitThe Yunhai-1 satellite is designed for detecting environmental elements in the atmosphere and ocean, the space environment, disaster prevention and reduction, and scientific experimentation. It is made by the Shanghai Institute of Spaceflight Technology.
Sun-Synchronous OrbitWorldView-4 is a commercial Earth observation satellite to be launched into sun-synchronous orbit. It is operated by DigitalGlobe, which provides imagery for customers such as NASA and Google Earth/Maps. Satellite is to deliver high-quality imagery, with a resolution of up to 31 cm in panchromatic mode, and a resolution of 1.24 m in multispectral mode. To be launched along with the satellite are 7 cubesats. These are tasked with testing various technologies, from data relay and radiation study to a new ion propulsion system.
Sun-Synchronous OrbitXPNAV-1 (X-Ray Pulsar Navigation) is the first ever satellite to test the technology of spacecraft navigation by using signals from X-ray pulsars. It is launched along with the Xiaoxiang 1 cubsat and several other small satellites.
Sun-Synchronous OrbitThis will be the maiden flight of the Long March 5, which is China's next-generation heavy-lift space launch system, comparable in performance to the European Ariane 5 and the U.S. Delta IV Heavy. The rocket is powered by RP-1 and Hydrogen, and will be able to place 25 tonnes into low earth orbit. It is carrying Shijian-17, an experimental satellite, reportedly tasked with testing ion propulsion systems for future space station keeping uses.
Geostationary OrbitHimawari-9 is a geostationary weather satellite operated by the Japan Meteorological Agency. It will be placed at 140 degrees East and will replace Himawari-8 in 2022. The satellite is about 3,500 kilograms and has a design life of around 15 years with operational life lasting 8 years.The main instrument aboard is a 16 channel multispectral imager to capture visible light and infrared images of the Asian-Pacific region.
Geostationary Transfer OrbitSoyuz MS-02 begins expedition 49 by carrying Roscosmos cosmonauts Sergei Ryzhikov, Andrei Borisenko and NASA astronaut Robert Kimbrough to the International Space Station. After launching from the Baikonur Cosmodrome in Kazakhstan, they will rendezvous to the station where they will remain for their 5 month stay.
