NASA Institute for Advanced Concepts

The NASA Innovative Advanced Concepts (NIAC), formerly NASA Institute for Advanced Concepts (NIAC), is a NASA program for development of far reaching, long term advanced concepts by "creating breakthroughs, radically better or entirely new aerospace concepts". It funds work on revolutionary aeronautics and space concepts that can dramatically impact how NASA develops and conducts its missions. The program operated under the name NASA Institute for Advanced Concepts from 1998 until 2007 (managed by the Universities Space Research Association on behalf of NASA), and was reestablished in 2011 under the name NASA Innovative Advanced Concepts and continues to the present.

The NASA Institute for Advanced Concepts (NIAC) was a NASA-funded program that was operated by the Universities Space Research Association (USRA) for NASA from 1998 until its closure on 31 August 2007. NIAC was to serve as "an independent open forum, a high-level point of entry to NASA for an external community of innovators, and an external capability for analysis and definition of advanced aeronautics and space concepts to complement the advanced concept activities conducted within NASA."

NIAC sought proposals for revolutionary aeronautics and space concepts to dramatically impact how NASA developed and conducted its missions. NIAC provided a highly visible, recognizable, and high-level entry point for outside thinkers and researchers. It encouraged proposers to think decades into the future in pursuit of concepts that would "leapfrog" the evolution of contemporary aerospace systems. These concepts were expected to be based on sound scientific principles and attainable within a 10 to 40-year time frame.

NIAC received a total of 1,309 proposals and awarded 126 Phase I grants and 42 Phase II contracts for a total value of $27.3 million from February 1998 to 2007.

NASA announced on March 1, 2011 that the NIAC concept would be re-established at NASA with similar goals, maintaining the acronym NIAC.

Studies funded by the original NIAC 1998–2007 include

On July 2, 2007, NIAC announced that "NASA, faced with the constraints of achieving the Vision for Space Exploration, has made the difficult decision to terminate NIAC, which has been funded by NASA since inception. Effective August 31, 2007, the original NIAC organization ceased operations.

Following the termination of the original NIAC program, Congress requested a review of the NIAC program by the United States National Research Council (NRC) of the National Academy of Sciences. The review was done in 2009, and concluded that in order to achieve its mission, NASA needs "a mechanism to investigate visionary, far-reaching advanced concepts," and recommended that NIAC, or a NIAC-like program, should be reestablished. Consistent with this recommendation, it was announced on March 1, 2011 that the NIAC was to be revived with similar goals leading to the establishment in 2011 of a project within the NASA Office of Chief Technologist, the NASA Innovative Advanced Concepts, maintaining the acronym NIAC. It is now part of the NASA Space Technology Mission Directorate (STMD).
