    Firefly Aerospace is preparing to launch QuickSounder on a Firefly Alpha Block 2 from Vandenberg SFB, CA, USA. QuickSounder is the first satellite mission of the Near Earth Orbit Network (NEON) program of the National Oceanic and Atmospheric Administration (NOAA), which aims to replace the current Joint Polar Satellite System (JPSS) series of polar orbit weather satellites. This pathfinder mission will demonstrate NOAA's ability to launch a small satellite within 3 years, flying a refurbished Advanced Technology Microwave Sounder (ATMS) instrument to polar orbit. Launch is planned for 15 February 2027, subject to confirmation.
