Of greatest importance are those phenomena that can threaten the safety of humans, such as astronauts and airline pilots, and the function of space systems, such as satellites and the International Space Station. After a brief introduction with examples, Dimitrios will discuss some of the latest satellites and instruments the National Oceanic and Atmospheric Administration (NOAA) has deployed to monitor, study, and model solar and space weather phenomena. Key among them are the Compact Coronagraph 1 (CCOR-1) launched on board the GOES-19 satellite in June 2024 and the Space Weather Follow On - Lagrange 1 (SWFO-L1) launched in September 2025 to continue the services provided by legacy NASA and NOAA missions. Dimitrios will discuss some of the key steps in planning for, designing, building, and operating spacecraft missionsImages and videos. Following the main presentation the recurring monthly presentations will include Constellation of the Month by Terri Zittritsch.
