The new processor is designed to allow spacecraft to analyze information, respond to unexpected situations, and make certain decisions without waiting for instructions from Earth. According to NASA, initial tests indicate a leap in performance compared to existing space computers.
NASA is developing a new generation of space computers that could change the way spacecraft operate far from Earth. At the center of the project is a new processor, small enough to fit in the palm of your hand, but much more powerful than the computers currently used in spacecraft. According to initial tests, the new processor could operate at up to 500 times the performance of radiation-hardened processors currently used in space.
The processor is being developed by NASA's High Performance Spaceflight Computing project, in collaboration with the Jet Propulsion Laboratory (JPL) and Microchip Technology. Its goal is to give spacecraft faster, independent processing capabilities that will enable them to handle more complex missions on the Moon, Mars, and deep space.
Why do spacecraft still use relatively old computers?
In space, the most powerful computer is not necessarily the most suitable computer. A spacecraft is required to operate for years in very harsh conditions: strong radiation from the sun and deep space, sharp temperature changes, shocks during launch and landing, and the inability to repair hardware after a malfunction. Therefore, many space missions use relatively old processors, chosen primarily for their reliability and durability.
The problem is that NASA's new missions require much more computing power. A spacecraft photographing a planet, a rover traveling across Mars, or a lander trying to land in a dangerous area have to process large amounts of data in a short time. The farther away the mission, the harder it is to rely on instructions from Earth, because communication is delayed.
A spacecraft that can respond in real time
The new processor is designed to enable spacecraft to use artificial intelligence and real-time data analysis. For example, a rover could self-detect an obstacle or an interesting scientific target. A lander could quickly process information from landing sensors to choose a safer path. A remote spacecraft could filter, compress, and prioritize scientific data before sending it back to Earth.
At JPL, the processor is tested in conditions that simulate the space environment. The tests include radiation, heat, shock, and performance in landing scenarios based on real NASA missions. Engineers check not only whether the chip is fast, but also whether it continues to operate stably when exposed to conditions that could damage sensitive electronics.
A step towards Moon, Mars and deep space missions
NASA sees the new processor as an important component in its future missions. It could be integrated into satellites around the Earth, rovers, manned habitats, missions to the Moon and Mars, and spacecraft that will operate at very great distances from Earth. The ability to perform more calculations on the spacecraft itself could accelerate scientific discoveries, reduce communications overhead, and improve mission safety.
According to NASA, the new processor is a system on a chip, SoC, meaning that many computer components are integrated into one small component. This type of technology is familiar from devices such as smartphones and tablets, but in this case it is adapted to work for years in an environment where there is no technician, no laboratory, and no easy way to replace a faulty component.
If the tests are successfully completed and the processor is approved for use in space, it could become one of the building blocks of the next generation of space missions. Instead of spacecraft that wait for every command from Earth, NASA is moving toward spacecraft that can understand more, respond faster, and make better use of their valuable time away from here.
Short FAQ
Why does NASA need a new processor for spacecraft?
Future space missions require rapid processing of information, response to unexpected situations, and the ability to act independently when communication with Earth is delayed.
What does radiation-hardened processor mean?
This is a processor designed to operate in harsh radiation conditions, where high-energy particles can cause errors in electronic systems.
How will the new processor help with space missions?
It will be able to process data from sensors, assist in landing, prioritize scientific information, and support spacecraft, landers, and rovers operating far from Earth.
