NASA has partnered with Microchip Technology Inc. to develop High-Performance Spaceflight Computing, a next-generation processor platform designed to dramatically increase onboard spacecraft computing power for upcoming missions to the Moon, Mars, and beyond.
Building on decades of experience with radiation-hardened processors dating back to the Apollo missions and Mars rovers, this new system-on-chip technology integrates computing and networking functions while achieving over 100 times the capability of existing space processors. The scalable design optimizes power consumption by shutting down unused functions, enabling efficient operation for complex, autonomous spaceflight tasks.
The processor family includes distinct versions tailored for different mission environments. A radiation-hardened variant targets geosynchronous, deep-space, and long-duration exploratory missions, capable of handling harsh conditions while supporting real-time autonomous operations. Meanwhile, a radiation-tolerant version aims at commercial low Earth orbit satellites, providing fault tolerance and enhanced cybersecurity.
Advanced Ethernet-based interconnects allow multiple sensors or chips to form clusters, boosting onboard data processing and enabling spacecraft to make autonomous decisions such as high-speed rover navigation or scientific data filtering. Integrated system health monitoring and security controllers ensure operational reliability and safety despite complexities.
This initiative is part of a nationwide public-private partnership that includes NASA’s Space Technology Mission Directorate’s Game Changing Development program, which manages the project through NASA’s Langley Research Center and Jet Propulsion Laboratory. The collaboration leverages a broad ecosystem of academic and industry partners, reinforcing U.S. leadership in spaceflight computing and strengthening supply chain resiliency.
Why it matters
The High-Performance Spaceflight Computing platform addresses the critical need for increased onboard processing power as space missions grow longer and more complex. Enhanced autonomy, fault tolerance, and cybersecurity capabilities will enable spacecraft to perform sophisticated tasks without reliance on Earth-based control, an essential advancement for future deep-space exploration and commercial satellite operations.
Furthermore, the technology’s adaptable design supports terrestrial applications in mission-critical edge computing across industries like automotive, aviation, energy, medical devices, and communications. This cross-sector utility helps reduce costs and risks for both government and commercial users while supporting domestic technological innovation and workforce development.
Background
Space computing began with NASA’s Apollo Guidance Computers in the 1960s and has since been essential to guiding spacecraft, operating rovers, and managing scientific instruments in extreme environments. Historically, NASA relied on radiation-hardened processors resistant to space radiation, albeit with limited computational power. The growing complexity of modern missions demands new processing solutions that offer significantly higher performance with enhanced energy efficiency and resilience.
By combining NASA’s mission requirements with Microchip’s commercial chip design expertise, the High-Performance Spaceflight Computing project exemplifies a strategic public-private partnership aimed at accelerating technology readiness for future space exploration.
