It has been almost 30 years since NASA has used the same spaceflight computers, but that won't last much longer. In order to develop a next-generation space-optimized processor.
the agency has awarded a $50 million contract to Arizona-based Microchip Technology Inc. A new chip will be 100 times faster than those currently used in lunar and planetary missions, NASA expects.
As we learned from Perseverance rover engineer Adam Steltzner, the robot's processor is no faster than a late 90s Mac computer - the phone in your pocket is an order of magnitude faster.
The latest Intel CPU won't suffice to power a spacecraft, however. As a result of extreme temperatures and damaging radiation, space is a harsh environment.
It is rare for regular computer hardware to last very long. Ingenuity Mars helicopters are one notable exception. Qualcomm's smartphone processor powers it, and despite NASA's low expectations, it's still working on Mars.
In spite of this, NASA demands the most robust hardware it can find when it comes to mission-critical hardware. The High-Performance Spaceflight Computing processor is a new chip developed by Microchip Technology. As a result, NASA missions in the future will have much improved capabilities, not just in terms of raw power.
A Microchip Technology processor promises 'advanced artificial intelligence processing, connectivity support, and fault tolerance.' At the same time, the processor is also radiation hardened and secure.
NASA started bidding last year for its new spaceflight processor. Specifically, it stated that the chip could handle a wide range of workloads efficiently. The current generation of spacecraft processors is designed to handle the most computationally intensive parts of the mission; for example, Curiosity and Perseverance's rocket sled landing sequences.
As a result, the system uses more power than needed for day-to-day activities, and when power is scarce, efficiency is compromised. According to Microchip Technology, the HPSC processor can be scaled up and down depending on the need and even have certain functionality completely disabled.
The HPSC processor is expected to be completed within three years by Microchip Technology. It may end up being a steal, too, if the $50 million fixed-cost contract works out.
The last designs were used for decades, and this one could be similarly durable as NASA transitions to a new era of planetary exploration. Similar stringent requirements could also be met by other government agencies.
