The Low-Earth Orbit (LEO) environment exhibits high variability in response to constantly changing inputs from both the Sun and the lower atmosphere. As “mega-constellations” of satellites are launched into LEO, it is imperative that we understand the variability in this region on a large range of time scales. Example impacts include thermospheric expansion in response to geomagnetic storming, with time scales of minutes, that alter the orbits of satellites and debris in LEO on time scales of hours to days, while intense radiation storms can cause system reboots or complete failure making it difficult to respond to induced collision threats. We invite talks and posters to discuss key gaps in our knowledge of the LEO environment and solutions that will ultimately enable the integration of environmental forecasting capabilities into space traffic management systems, ensuring the safety and viability of orbital operations for future generations.
