NASA's new space processor is 500 times faster than what's flying today
NASA has a new radiation-hardened processor that outperforms every chip currently running in deep space — by a factor of 500. Built with Microchip Technology under NASA's Game Changing Development program, the High Performance Spaceflight Computing (HPSC) chip completed its first symbolic test in February 2026, when engineers sent a "Hello Universe" email through it at JPL. Full radiation, thermal, and shock testing runs through May 2026.
The numbers
The original target was 100 times the computing power of today's space-rated processors. Lab results at JPL blew past that: NASA JPL official benchmarks showed 500x performance over current radiation-hardened chips in use on active missions. To put that in perspective, Mars rovers today rely on computing power roughly equivalent to a mid-1990s desktop — useful, but not capable of real-time decision-making on difficult terrain.
The HPSC is a modular system-on-chip (SoC) combining CPU cores, memory, and networking in a single package. Engineers can switch blocks off when full power isn't needed, extending battery life on long missions. The architecture is built on open-source RISC-V — the same instruction set gaining traction in commercial silicon — which means software ecosystems can grow around it faster than proprietary alternatives.
Why this matters for Artemis — and beyond
Signal delay is the core problem in deep-space missions. A command sent from Earth to Mars can take up to 24 minutes one way. A rover that can't act without human approval is a rover that doesn't act quickly enough. The HPSC is designed to change that: onboard processing powerful enough to analyze soil composition in real time, plot routes through rough terrain autonomously, and manage life-support systems on future lunar bases without waiting for a ground team's sign-off.
NASA is targeting the HPSC for Artemis lunar missions, with a crewed landing aimed at early 2028. The chip must clear JPL certification by late 2026 to stay on that schedule. Per the Microchip PIC64-HPSC product page, the platform supports Linux and RTEMS, making it easier to port existing flight software.
Earth-side spin-offs
Microchip Technology is already adapting the design for commercial use — aviation safety systems and autonomous vehicles are the stated targets, sectors where a single hardware fault can be catastrophic. No production roadmap or pricing has been announced yet, and early-access samples have so far gone only to US defense and aerospace contractors. A broader commercial rollout is unlikely before 2027 at the earliest.
The 500x figure comes from controlled lab benchmarks, and real-world mission performance will depend on workload. But even a fraction of that gain would represent a genuine step change for spacecraft that have been running on 1990s-era computing for decades.
