Description

As meteoroids enter the Earth’s atmosphere, their momentum turns into heat, generating high-temperature plasma surrounding their body. These plasmas, referred to as meteors, have been studied for well over a century, yet many outstanding questions remain. In addition, space debris, also known as orbital debris, space junk, and space waste, is the collection of objects in orbit around Earth that were created by humans but no longer serve any useful purpose. These artificial meteors/Debris and meteoroids of astronomic origin are a long-standing threat to satellites, and both contribute to the flux of macroscopic particles into Earth's atmosphere. To address the outstanding questions currently under investigation in the field of meteor, meteoroid and debris science and engineering, we invite presentations on the physics of meteoroid and debris particles and their impacts effects on the atmosphere, ionosphere, and satellites. We encourage presentations that address the engineering techniques for observing and characterizing the meteoroid and debris population, including any observational (i.e. lidar, radar, satellite and optical) or modeling methods. We also welcome presentations that use AI and machine learning techniques to study all types of meteor echoes and space debris.

Justification

These plasmas, referred to as meteors, have been studied for well over a century, yet many outstanding questions remain. In addition, space debris, also known as orbital debris, space junk, and space waste, is the collection of objects in orbit around Earth that were created by humans but no longer serve any useful purpose. These artificial meteors/Debris and meteoroids of astronomic origin are a long-standing threat to satellites, and both contribute to the flux of macroscopic particles into Earth's atmosphere. Several recent network of multi-static meteor radars, a regional network of radar systems, and regional optical instruments have recently been funded. In addition, there are new efforts worldwide in developing lower cost radar systems that can enable new research and discovery, broadening the participation of underrepresented communities. Additionally, the utilization of AI and machine learning to conduct meteor and space debris research can open new frontiers or research in space science.
