State-of-the-art contrails detection in MTI magazine

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

Avoid Connection Breakdown for Space-to-Ground Communication

Unlike traditional radio frequency systems, lasercomm offers dramatically higher bandwidth and enhanced security, making it a key enabler for next-generation satellite missions and data-hungry applications. However, this leap in capability comes with new vulnerabilities—particularly the sensitivity of optical signals to atmospheric conditions. Even minor disruptions, such as cloud cover or atmospheric turbulence, can severely degrade or interrupt the laser link between space assets and ground

All-sky imagers for next level contrails observations

The European Union has been taking a groundbreaking step in addressing aviation’s climate impact by introducing mandatory monitoring and reporting of non-CO₂ emissions, including contrails, from January 2025. This initiative is part of the EU Emissions Trading System (EU ETS) framework and represents the first large-scale effort globally to systematically track contrails from flights within the European Economic Area (EEA). Contrails, which form when
