Missions

While the spacecraft continues to return science data and otherwise operate as normal, the mission team is searching for the source of a system data issue.

The rocks Perseverance has analyzed for sample collection are helping the team better understand a past marked by volcanic activity and water.

Six decades after the launch of the first nuclear-powered space mission, Transit IV-A, NASA is embarking on a bold future of human exploration and scientific discovery.

This Sources Sought Notice seeks capabilities, innovative ideas for new system development, fiscal estimates, and potential collaboration that could lead to an industry/Government contract for development of a Dynamic Radioisotope Power System (DRPS) for use on the moon with desired extensibility to other solar system destinations.

Humanity's first and (so far) last visit to the outermost giant planet in our solar system was a monumental event for scientists and the public alike.

Two NASA scientists studying next-generation thermoelectric materials and converters for applications to radioisotope power systems have been awarded the 2019 Outstanding Achievement Award by the International Thermoelectric Society for their decades-long leadership and contributions to the field.
