Priorities in Space Science Enabled by Nuclear Power and Propulsion

In 2003, NASA began an R&D effort to develop nuclear power and propulsion systems for solar system exploration. This activity, renamed Project Prometheus in 2004, was initiated because of the inherent limitations in photovoltaic and chemical propulsion systems in reaching many solar system objectives. To help determine appropriate missions for a nuclear power and propulsion capability, NASA asked the NRC for an independent assessment of potentially highly meritorious missions that may be enabled if space nuclear systems became operational. This report provides a series of space science objectives and missions that could be so enabled in the period beyond 2015 in the areas of astronomy and astrophysics, solar system exploration, and solar and space physics. It is based on but does not reprioritize the findings of previous NRC decadal surveys in those three areas.

An Enabling Foundation for NASA's Earth and Space Science Missions

NASA's space and Earth science program is composed of two principal components: spaceflight projects and mission-enabling activities. Most of the budget of NASA's Science Mission Directorate (SMD) is applied to spaceflight missions, but NASA identifies nearly one quarter of the SMD budget as "mission enabling." The principal mission-enabling activities, which traditionally encompass much of NASA's research and analysis (R&A) programs, include support for basic research, theory, modeling, and data analysis; suborbital payloads and flights and complementary ground-based programs; advanced technology development; and advanced mission and instrumentation concept studies. While the R&A program is essential to the development and support of NASA's diverse set of space and Earth science missions, defining and articulating an appropriate scale for mission-enabling activities have posed a challenge throughout NASA's history. This volume identifies the appropriate roles for mission-enabling activities and metrics for assessing their effectiveness. Furthermore, the book evaluates how, from a strategic perspective, decisions should be made about balance between mission-related and mission-enabling elements of the overall program as well as balance between various elements within the mission-enabling component. Collectively, these efforts will help SMD to make a good program even better.

Report Series: Committee on Astrobiology and Planetary Science

Getting Ready for the Next Planetary Science Decadal Survey

By: National Academies of Sciences, Engineering, and Medicine,Division on Engineering and Physical Sciences,Space Studies Board,Committee on Astrobiology and Planetary Science

This study discusses the publicly available studies of future flagship- and New Frontiers-class missions NASA initiated since the completion of Vision and Voyages. The report considers the priority areas as defined in Vision and Voyages where publicly available mission studies have not been undertaken; appropriate mechanisms by which mission-study gaps might be filled in the near- to mid-term future; and other activities that might be undertaken in the near- to mid-term future to optimize and/or expedite the work of the next planetary science decadal survey committee.

Radioisotope Power Systems

An Imperative for Maintaining U.S. Leadership in Space Exploration

Radioisotope Power Systems

An Imperative for Maintaining U.S. Leadership in Space Exploration

By: National Research Council,Division on Engineering and Physical Sciences,Aeronautics and Space Engineering Board,Space Studies Board,Radioisotope Power Systems Committee

Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions-the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.

Launching Science

Science Opportunities Provided by NASA's Constellation System

In January 2004 NASA was given a new policy direction known as the Vision for Space Exploration. That plan, now renamed the United States Space Exploration Policy, called for sending human and robotic missions to the Moon, Mars, and beyond. In 2005 NASA outlined how to conduct the first steps in implementing this policy and began the development of a new human-carrying spacecraft known as Orion, the lunar lander known as Altair, and the launch vehicles Ares I and Ares V. Collectively, these are called the Constellation System. In November 2007 NASA asked the National Research Council (NRC) to evaluate the potential for new science opportunities enabled by the Constellation System of rockets and spacecraft. The NRC committee evaluated a total of 17 mission concepts for future space science missions. Of those, the committee determined that 12 would benefit from the Constellation System and five would not. This book presents the committee's findings and recommendations, including cost estimates, a review of the technical feasibility of each mission, and identification of the missions most deserving of future study.
