Open-Source Science Initiative

NASA is making a long-term commitment to building an inclusive open science community over the next decade. Open-source science is a commitment to the open sharing of software, data, and knowledge (algorithms, papers, documents, ancillary information) as early as possible in the scientific process. The principles of open-source science are to make publicly funded scientific research transparent, inclusive, accessible, and reproducible. Advances in technology, including collaborative tools and cloud computing, help enable open-source science, but technology alone is insufficient. Open-source science requires a culture shift to a more inclusive, transparent, and collaborative scientific process, which will increase the pace and quality of scientific progress.

To help build a culture of open science, NASA is championing a new initiative: the Open-Source Science Initiative (OSSI). OSSI is a comprehensive program of activities to enable and support moving science towards openness, including policy adjustments, supporting open-source software, and enabling cyberinfrastructure. OSSI aims to implement NASA’s Strategy for Data Management and Computing for Groundbreaking Science 2019-2024, which was developed through community input.

Upcoming: NASA Transform to Open Science Community Forum

As NASA’s Transform to Open Science (TOPS) moves into the upcoming 2023 Year of Open Science, the TOPS team will regularly update the community on these activities, highlight open science success stories and lessons learned, Q&A, and other open science news in a series of TOPS Community Forums. We invite you to join us 2:00-3:00pm, Eastern, May 12th, for NASA TOPS Community Forum. To view full details regarding this opportunity and to register go to Learn more.

SPD-41 Science Information Policy

We have recently released Science Mission Directorate (SMD) Policy: SPD-41: The Science Information Policy. This policy consolidates existing guidance on maximizing the openness and accessibility of the information that SMD produces. Learn More

We’ve also released a Request for Information to gather feedback on the implementation to the information policy  and on the impact of the proposed changes to SPD-41.


Why do Open Science?


  • Broadens participation and fosters greater collaboration in scientific investigations by lowering the barriers to entry into scientific exploration
  • Generates greater impact and more citations to scientific results
