Voyager 1, a space probe that has been traveling through interstellar space for nearly 50 years, carries six computers with a combined memory of 68 kilobytes. This might seem like a tiny amount of storage, but it's not a fair comparison to a modern smartphone. The memory is divided among three specialized computer systems, each with its own role and design, rather than being a shared storage drive. This setup was deliberate, as the computers were built for specific tasks, not to run a display, apps, or wireless networking. The probe's narrow purpose allowed it to be flexible, and the team could upload new sequences and alter software to adapt to failures and new situations. However, the limited memory has become a challenge as the probe ages and its electrical power declines. The recent failure of a chip holding part of the FDS memory highlights the fragility of the system. With only two science instruments still operational, the question is how long the remaining systems can keep doing their jobs. This raises a deeper question about the sustainability of space exploration and the limitations of technology in the face of time and the harsh environment of space.
