CLARREO Pathfinder-on-ISS
International Space Station/Climate Absolute Radiance & Reflectivity Observatory Pathfinder
| NASA | Approved | Dec 2023 | Apr 2024 | 1 year nominal mission. The goal of the Climate Absolute Radiance and Refractivity Observatory (CLARREO) mission is to improve our understanding of climate change by providing high accuracy measurements of the change in key climate variables over decadal timescales. CLARREO Pathfinder is a technical demonstration on the ISS and a major step in reducing the cost and technical risk for these high accuracy measurements. | CLARREO Pathfinder Reflected Solar | Type: Inclined, non-sun-synchronous

CO2Image
CO2Image
| DLR | Approved | May 2026 | May 2029 | Mission Goal: The mission shall demonstrate the feasibility of verifying carbon dioxide emissions from localized sources such as coal-fired power plants down to medium source strength (>1 MtCO2/yr) worldwide. Application: Independent verification of reported emissions as a cornerstone toward emission accounting and reduction measures such as agreed on in the Paris climate agreement. In 2018, coal-fired power plants accounted for 30% of the global man-made carbon dioxide emissions. | COSIS | Type: Sun-synchronous
