Spaceflight and Earth’s Atmosphere: How the Coming Era of Larger and More Frequent Rocket Launches and Space Debris Reentries Could Affect Global Climate, Ozone, High-Altitude Clouds, and Upper Atmosphere.
Session ID#: 251495
Session Description:
The emergence of new technologies and commercial opportunities in low earth orbit (LEO) have given rise to a fast-growing global space industry. Rocket engines and vaporizing space debris emit gases and aerosols into all layers of the atmosphere, leading to potential impacts on ozone, mesospheric cloudiness, ground-based astronomy, and the thermosphere/ionosphere space weather environment. Quantification of these impacts are difficult due to the uncertainty of space sector expansion, defining pollutant chemical and radiative properties, and a scarcity of observational experiments. The purpose of this session is to highlight new understanding of the potential impacts of spaceflight emissions on Earth’s atmosphere, and to discuss the research programs that are required to close the most critical knowledge gaps. This session welcomes presentations regarding spaceflight’s impacts on the all layers of the atmosphere, interference to astronomy and LEO space operations, new observational data and atmospheric modeling results, and scenarios of future emissions.
