NASA’s Science Mission Directorate (SMD) is making a long-term commitment to support building an inclusive open science community over the next decade via the Open-Source Science Initiative (OSSI). A key component of OSSI is the Transforming to OPen Science (TOPS) project. The TOPS project will coordinate efforts designed to accelerate scientific discovery and equity with open science. SMD has declared 2023 as the Year of Open Science within a five-year effort to transform to open science. During 2023, NASA will initiate a suite of coordinated activities designed to support adoption of open science.
