# SFL Missions GHGSat satellite development and deployment > Live situation record from CLSTR: https://clstr.news/situations/sfl-missions-ghgsat-satellite-development-and-deployment > Updated: 2026-10-03T00:29:14.000Z. Sources: 5. Developments: 2. SFL Missions is expanding its satellite development and deployment capabilities for GHGSat to monitor greenhouse gas emissions. In late September 2026, SFL Missions was awarded a contract to develop the GHGSat-D2 demonstration satellite. This mission utilizes the expanded DEFIANT-XL bus to accommodate a high-accuracy sensor from ABB Canada, aiming to provide more precise measurements of methane emissions from smaller ground sources. The satellite is expected to weigh nearly 100 kg. Separately, on October 1, 2026, SFL Missions successfully deployed two microsatellites, GHGSat-C18 (Eleanor) and GHGSat-C19 (Aidan), via a SpaceX Transporter 18 mission. These 15-kg satellites, built on the NEMO platform, join a constellation of 13 spacecraft designed to provide emissions data to sectors such as mining, agriculture, and oil and gas to support decarbonization. ## Timeline ### 2026-10-03: SFL Missions deploys two GHGSat greenhouse gas monitoring satellites SFL Missions successfully deployed two GHGSat microsatellites via SpaceX to monitor greenhouse gas emissions from orbit, bringing the company's total satellite count to 13. 2 sources. https://clstr.news/cluster/sfl-missions-deploys-two-ghgsat-greenhouse-gas-monitoring-satellites ### 2026-09-28: SFL Missions awarded contract for GHGSat greenhouse gas monitoring satellite SFL Missions will develop the GHGSat-D2 demonstration satellite, using an expanded DEFIANT-XL bus to enhance the accuracy and frequency of space-based greenhouse gas and methane monitoring. 3 sources. https://clstr.news/cluster/sfl-missions-awarded-contract-for-ghgsat-greenhouse-gas-monitoring-satellite --- Cite as: SFL Missions GHGSat satellite development and deployment.
