NASA is building autonomous spacecraft computers powerful enough to make deep space decisions completely without human intervention

NASA claims its new radiation-hardened chip delivers up to 100 times more computing power than current spaceflight hardware, and early test results have even shown performance levels roughly 500 times greater than existing radiation-protected processors.

“Building on the legacy of previous space processors, this new multicore system is fault-tolerant, flexible, and extremely high-performing,” said Eugene Schwanbeck, a program manager at NASA Langley Research Center.

Any processor destined for deep space must endure extreme electromagnetic radiation and dramatic temperature swings.

High-energy particles from the Sun can easily trigger computer errors that force conventional spacecraft into a protective “safe mode.”

Engineers at NASA’s Jet Propulsion Laboratory are subjecting the prototype to punishing simulations of these conditions.

“We are putting these new chips through the wringer by carrying out radiation, thermal, and shock tests,” explained Jim Butler, the project manager for High Performance Space Computing at JPL.

The chip must also handle the unique challenges of planetary landings without human intervention.

What to read next

These dramatic improvements raise a legitimate question about whether engineers have considered the potential risks of truly autonomous machines.

Science fiction enthusiasts reading this might immediately recall 2001: A Space Odyssey, where a thinking computer named HAL tragically malfunctions in a story serving as a cautionary tale about granting machines too much independent authority over human lives.

NASA now envisions spacecraft that can process scientific data instantly and respond to unexpected hazards without waiting for instructions from Earth.

The agency is testing how the chip handles high-fidelity landing scenarios that would normally require power-intensive hardware to process massive sensor data volumes.

One must acknowledge that modern spacecraft already rely on automated systems for many routine functions.

The difference here lies in the scale of autonomy and the use of onboard artificial intelligence for mission-critical decisions.

NASA’s collaboration with Microchip Technology has already produced sample chips for defense and commercial aerospace partners.

The finished processor could eventually support crewed missions to the Moon and Mars, where communication delays of several seconds would make real-time human control impractical.

Whether this technological leap invites unforeseen risks remains an open question – after all, HAL’s famous line, “I’m sorry, Dave, I’m afraid I can’t do that,” began with the best engineering intentions.
