NASA and Microchip Aim to Revolutionize Processors for Future Space Missions
In recent times, one of the "hot" topics is orbital data centers for Artificial Intelligence, but computers have been fundamental, are fundamental, and will be even more critical for future space missions. NASA is keenly interested in technological evolution, from the guidance computers used during the Apollo missions to the onboard computing systems of Mars rovers; the hardware employed must be suitable for operation in hostile environments.
In 2022, a contract was awarded for the development of the next generation of processors for High‑Performance Spaceflight Computing (HPSC), which aim to revolutionize the operational capabilities of various missions, not only in terms of performance but also in adapting better to the needs of modern space exploration. This family of processors has been developed in collaboration with Microchip Technology, through a public-private partnership, promising to redefine the standards for space computing.
NASA and Microchip Together for Future Space Processors
The HPSC project introduces a System-on-a-Chip (SoC) capable of offering over one hundred times the performance of currently used processors. The integration of computing capabilities and networking functions into a single device helps to reduce costs, complexity, and energy consumption, a crucial factor for long-duration missions and vehicles that must operate autonomously. The architecture is scalable: unnecessary functions can be turned off to save energy while critical ones remain operational at maximum efficiency. This modular approach allows the chip to be adapted for very different missions, from commercial satellites in low Earth orbit to vehicles headed for Mars.
The HPSC family includes two main variants. The radiation-hardened version is designed for missions in extreme environments, such as geostationary orbits, the Moon, Mars, and deep space, where radiation can quickly compromise traditional electronics. It ensures continuous operation even under high doses of radiation and supports real-time autonomous functions. The radiation-tolerant version, on the other hand, is intended for the commercial sector and low Earth orbit satellites, with a particular focus on fault tolerance and cybersecurity.
Thanks to advanced Ethernet connections, multiple chips can be connected in clusters or integrated with complex sensors, allowing spacecraft to process huge amounts of data directly onboard. The ability to avoid sending large amounts of data back to Earth increases operational efficiency. Moreover, an integrated security controller and continuous monitoring of the system's health ensure that these operations remain reliable even under critical conditions.
Interestingly, while these processors are designed for space, they are not limited to that environment. In fact, the chips can also be used for edge computing, avionics, industrial systems, energy networks, medical devices, drones, and artificial intelligence applications. Once again, the aim is to increase efficiency while reducing overall development and production costs. Their debut is expected in the coming years, also thanks to the Artemis program, but their use may continue well beyond 2040 in NASA's vision.
