This bill reauthorizes the National Aeronautics and Space Administration (NASA) through FY2019.

The bill authorizes NASA programs, activities, and reports, including those regarding the International Space Station (ISS); launch, crew, and cargo vehicle critical path redundancy; space suits; earth observation; land remote sensing data collection; Landsat systems; the Goddard Institute for Space Studies; in-space nuclear fission power; civil supersonic transportation research; unmanned aircraft systems research; commercially provided space products and services; commercial in-space infrastructure; and NASA-funded institutes.

NASA shall:

• continue the operation of the ISS;
• establish a research office at the Johnson Space Center to build upon its expertise in human space flight missions for future challenges;
• partner with private sector and philanthropic organizations to search for technosignatures, such as radio transmissions, in the search for life's origin and future in the universe;
• establish the 21st Century Aeronautics Research Capabilities Initiative;
• more effectively and efficiently share its electromagnetic spectrum with U.S. nongovernmental entities operating or proposing to operate space objects; and
• restrict contracting with contractors who have a history of poor performance on space contracts.

The bill extends NASA's authority to lease nonexcess properties through 2020.

The National Space Council shall publish a report that relates the strategic national importance of space to the inherent risk of exploring and using it.
