While global attention is often monopolized by the Jet Propulsion Laboratory (JPL) and its Curiosity-class vehicles, Chinese space engineering reached a critical milestone with the Tianwen-1 mission. Landing in May 2021 on the vast plains of Utopia Planitia, the Zhurong rover represents more than just a political success; it is a tangible demonstration of advanced autonomous robotics.

The 2.7 Billion Paradox

Imagine designing the most sophisticated vehicle ever built by humanity, a mobile laboratory costing 2.7 billion, destined to search for traces of ancient life on another planet. Now, imagine having to pilot it using a "brain" less powerful than the one on your wrist right now.

BAE Systems RAD750

This is the reality of aerospace engineering. NASA’s Perseverance rover operates on a BAE Systems RAD750 processor. It is a Rad-Hard component (resistant to ionizing radiation) based on PowerPC architecture from the late 90s, with a clock speed of just 200 MHz. To put it brutally: your smartphone chip is hundreds of times faster.
