Cosmic radiation poses a significant threat to data integrity aboard Voyager spacecraft.

Beyond the heliopause, the influence of the sun wanes and Voyager spacecrafts must navigate through a sea of cosmic radiation.

This heightened exposure increases the likelihood of bit flips - a critical concern for the reliability of stored data.

Memory Limitations and Redundancy

With only 70KB of memory, Voyager spacecrafts cannot afford excess redundancy to combat bit flips caused by cosmic radiation.

Implementing mirrored arrays that require excessive replicas for each piece of data is not feasible with their limited storage capacity.

Data Integrity Techniques

While specific data integrity techniques employed on Voyager spacecrafts are undisclosed, advanced encoding schemes, such as Hamming codes, are crucial for mitigating the impact of cosmic radiation on data integrity.

The utilization of Hamming codes ensures superior error-detection and correction capabilities without the need for excessive redundancy.

Continuous Quest for Data Reliability

As Voyager spacecrafts journey further into the cosmos, the relentless assault of cosmic radiation necessitates a continuous pursuit of enhancing data reliability.

Their enduring exploration serves as a testament to human resilience and technological ingenuity in the face of cosmic adversities.
