What is Space Situational Awareness (SSA)? Space Situational Awareness (SSA) means being able to see, track, and study objects in orbit. This includes active and inactive satellites, debris, asteroids, and space weather. SSA keeps space activities safe and sustainable. In recent years, the need to track and understand the space environment has grown a lot for many reasons. The proliferation

Aviation's environmental footprint extends beyond just CO2. Non-CO2 effects like nitrogen oxide emissions and contrails also significantly influence climate change. Although contrails may seem minor, their cumulative warming effect could notably contribute to global warming by 2050. Understanding and mitigating this impact is essential for a more sustainable aviation future. Collaborative Efforts to Reduce Contrail Impact Several airlines are testing flight rerouting strategies to
