Modern science is ever more driven by computations and simulations. In particular, the state of the art in space and Earth science often arises from complex simulations of climate, space weather, and astronomical phenomena. At the same time, scientific work requires data processing, presentation, and analysis through broadly available proprietary and community software.1 Implicitly or explicitly, software is central to science. Scientific discovery, understanding, validation, and interpretation are all enhanced by access to the source code of the software used by scientists. This report investigates and recommends options for NASA's Science Mission Directorate (SMD) as it considers how to establish a policy regarding open source software to complement its existing policy on open data. In particular, the report reviews existing data and software policies and the lessons learned from the implementation of those policies, summarizes community perspectives, and presents policy options and recommendations for implementing an open source software policy for NASA SMD.

In this real life spy saga, James E. David reveals the extensive and largely hidden interactions between NASA and U.S. defense and intelligence departments. The story begins with the establishment of NASA in 1958 and follows the agency through its growth, not only in scope but also in complexity. In Spies and Shuttles, David digs through newly declassified documents to ultimately reveal how NASA became a strange bedfellow to the Department of Defense (DoD) and the Central Intelligence Agency (CIA). He tracks NASA’s early cooperation—supplying cover stories for covert missions, analyzing the Soviet space program, providing weather and other scientific data from its satellites, and monitoring missile tests—that eventually devolved into NASA’s reliance on DoD for political and financial support for the Shuttle. David also examines the restrictions imposed on such activities as photographing the Earth from space and the intrusive review mechanisms to ensure compliance. The ties between NASA and the intelligence community have historically remained unexplored, and David’s riveting book is the first to investigate the twists and turns of this labyrinthine relationship.
