Artemis II is a scheduled mission of the NASA-led Artemis program. It will use the second launch of the Space Launch System (SLS) rocket and include the first crewed mission of the Orion spacecraft. The mission is scheduled to take place no earlier than April 2026. Four astronauts will perform a flyby of the Moon and return to Earth, becoming the first crew to travel beyond low Earth orbit since Apollo 17 in 1972. Artemis II will be the first crewed launch from Launch Complex 39B of the Kennedy Space Center since STS-116 in 2006.
The Geostationary Operational Environmental Satellite (GOES), operated by the United States’ National Oceanic and Atmospheric Administration (NOAA)’s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research. Spacecraft and ground-based elements of the system work together to provide a continuous stream of environmental data. The National Weather Service (NWS) and the Meteorological Service of Canada use the GOES system for their North American weather monitoring and forecasting operations, and scientific researchers use the data to better understand land, atmosphere, ocean, and climate dynamics.
The fourth-generation satellites, the GOES-R series, were built by Lockheed Martin using the A2100 satellite bus. The GOES-R series is a four-satellite program (GOES-R, -S, -T and -U) intended to extend the availability of the operational GOES satellite system through 2036. GOES-R launched on 19 November 2016. It was renamed GOES-16 upon reaching orbit. Second of the series GOES-S, was launched on 1 March 2018. It was renamed GOES-17 upon reaching orbit.
The instrument package for the GOES-R series includes:
Advanced Baseline Imager (ABI)
Space Environment In-Situ Suite (SEISS), which includes two Magnetospheric Particle Sensors (MPS-HI and MPS-LO), an Energetic Heavy Ion Sensor, and a Solar and Galactic Proton Sensor
Solar Imaging Suite, which includes the Solar Ultraviolet Imager (SUVI), the Solar X-Ray Sensor (XRS), and the Extreme Ultraviolet Sensor (EUVS)
Geostationary Lightning Mapper (GLM)
Magnetometer
