NASA is currently testing a new artificial intelligence chip designed to significantly increase the computational power of spacecraft. This radiation-hardened processor, developed under the High Performance Spaceflight Computing project, has demonstrated performance levels up to 500 times greater than existing chips used in spaceflight. The advancement aims to allow spacecraft to operate with greater autonomy, a critical capability for missions facing long communication delays with Earth.
The new chip is undergoing rigorous testing at NASA's Jet Propulsion Laboratory (JPL) to ensure it can withstand the harsh conditions of space, including radiation, extreme temperatures, and vibration. Current space electronics often rely on older, slower processors chosen for their durability rather than their speed. This new processor, however, is designed to be both resilient and powerful, integrating dedicated neural processing units alongside its core computing capabilities. Early results from testing, which began in February 2026, have been highly encouraging, showing the processor functioning as intended.
This development is expected to enable spacecraft to perform complex tasks autonomously. For instance, a rover could analyze unexpected geological findings in real time and adjust its course without waiting for instructions from mission control. Such onboard intelligence is essential for deep space exploration, where communication round trips can take minutes to hours. The chip could also accelerate scientific discovery by allowing spacecraft to process and analyze vast amounts of data locally, reducing the need to transmit raw information back to Earth.
The High Performance Spaceflight Computing (HPSC) project is a collaboration that has involved partnerships with companies like Microchip Technology. The processor is a system-on-a-chip (SoC), meaning it integrates multiple computing and networking functions onto a single device. This integration is intended to reduce complexity, improve power efficiency, and provide a scalable architecture that can conserve energy by turning off unnecessary functions.
Potential applications for this technology include more intelligent rovers for missions to the Moon and Mars, such as autonomous scientists that can formulate hypotheses and collect samples. It could also support crewed missions by providing enhanced decision-making capabilities in critical situations. The processor's resilience to radiation makes it suitable for environments with high radiation levels, such as Jupiter's moons.
This new processor builds upon NASA's legacy of developing radiation-hardened components for space exploration. Instruments like the Planetary Instrument for X-ray Lithochemistry (PIXL) on the Perseverance rover, for example, demonstrate the agency's capability in creating sophisticated tools for detailed scientific analysis on other planets. PIXL uses an X-ray beam to map the elemental chemistry of Martian rocks at high resolution, aiding in the search for biosignatures. While PIXL focuses on detailed chemical analysis, the new AI chip aims to enhance the decision-making and processing capabilities of the spacecraft itself.
The testing phase is expected to continue for several more months. Following successful completion of these trials, the processor is anticipated to be incorporated into future NASA missions.
