NAOS (National Advanced Optical System) is the space component of Luxembourg's governmental dual-use observation satellite system LUXEOSys (Luxembourg Earth Observation System). Its purpose is to provide high resolution images to national and international governmental and military organizations such as NATO. The 800 kg satellite is built by OHB Italia and is equipped with a very high-resolution optical camera with a ground reolution of 50 cm in an around 450 km high sun-synchronous orbit. It will have a operational life time of 7 years.
Sun-Synchronous 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.
Polar OrbitThe Electro-Optical/Infrared Weather System (EWS) Operational Demonstration-1 (OD-1) is a weather satellite for the United States Space Force. It is a prototype satellite made by General Atomics that will be place in LEO for a three-year demonstration mission of new EO/IR sensor technologies to various US military branches, and to act as a stop-gap for Defense Department needs for weather data.
