NASA's New Space Processor Gives Spacecraft Autonomous Decision-Making Power
NASA is developing a radiation-hardened processor that could enable spacecraft to operate independently in deep space, making real-time decisions without waiting for commands from Earth. The High Performance Spaceflight Computing processor, built through a partnership with Microchip Technology Inc., delivers up to 500 times the computing power of current spaceflight chips while surviving the extreme conditions of space.
The processor represents a shift in how future missions will function. Current spacecraft rely on older, slower processors because they can withstand radiation and temperature extremes. Those limitations force mission planners to keep spacecraft dependent on ground control, even when communication delays make real-time human input impossible.
What the New Processor Does
The chip is a system-on-a-chip (SoC)-a single device small enough to fit in a palm that combines central processing units, memory, networking systems, and input/output interfaces. It functions like the processors in smartphones, but built to operate for years millions of miles from Earth.
NASA says the processor enables three critical capabilities:
- Autonomous spacecraft that use artificial intelligence to react to unexpected situations where communication delays make human input impossible
- Rapid analysis and transmission of massive scientific data volumes during deep space missions
- Support for crewed missions to the Moon and Mars, including onboard processing for landing scenarios
Testing and Performance
Engineers at NASA's Jet Propulsion Laboratory have been subjecting the processor to radiation, thermal, and shock tests since February. Jim Butler, the High Performance Space Computing project manager at JPL, said the team is "putting these new chips through the wringer" by simulating real landing scenarios from actual NASA missions.
Early results show the processor functioning as expected. The team marked the start of testing with an email subject line: "Hello Universe"-a nod to computing's early days.
To qualify for spaceflight, the processor must withstand high-energy particles from the Sun that can create errors forcing spacecraft into safe mode. It must also survive violent shocks and temperature swings that damage standard electronics.
Timeline and Industry Adoption
Testing will continue for several more months. Once certified, NASA plans to integrate the processor into Earth orbiters, planetary rovers, crewed habitats, and deep space spacecraft.
Microchip has already shared early versions with partners in defense and commercial aerospace. The company also plans to adapt the technology for aviation and automotive manufacturing on Earth.
Eugene Schwanbeck, program element manager in NASA's Game Changing Development program at Langley Research Center, said the project builds on decades of space processor development. "This new multicore system is fault-tolerant, flexible, and extremely high-performing," he said.
