Summary:
- The article discusses a failure in the Hubble Space Telescope's payload computer, which is responsible for controlling and coordinating the telescope's scientific instruments.
- The issue was traced back to a single malfunctioning memory module, which caused the computer to repeatedly restart and prevented the telescope from carrying out scientific observations.
- NASA engineers were able to switch to a backup memory module and restore the telescope's operations, demonstrating the resilience and redundancy built into the Hubble's design.
