# Hubble's Ongoing Challenges: What's Ahead for the Space Telescope?
Written on
Chapter 1: Hubble's Current State
The Hubble Space Telescope continues to be out of service following a failure in its payload computer that was identified on June 13. The malfunction has been traced to the Science Instrument Command and Data Handling unit, which houses the defective payload computer. Repair teams are also investigating the Command Unit/Science Data Formatter responsible for transmitting and formatting data, as well as a power regulator in the power control unit.
If any of these components are confirmed as the cause of the malfunction, engineers will transition Hubble to its backup systems. This switch is complex, and mission engineers are currently devising protocols for the operation, which will be tested using simulators prior to executing commands on Hubble.
> "NASA has finalized preparations to test procedures in the upcoming week that would activate Hubble's backup hardware in response to the payload computer malfunction. The investigation into the root cause is still ongoing," the Hubble team shared via Twitter on July 2.
Section 1.1: Initial Attempts to Troubleshoot
NASA initially tried to engage the backup payload computer hardware and memory modules, but these efforts did not resolve the issues with Hubble.
"Subsequent tests conducted on June 23 and 24 involved activating the backup computer for the first time in orbit. These tests revealed that various combinations of hardware from both the primary and backup payload computers experienced identical errors — commands to read from or write to memory were unsuccessful," as stated by NASA.
Section 1.2: Preparing for Backup Activation
Transitioning to the backup payload computer hardware and memory modules will also necessitate switching several other hardware units aboard the orbiting observatory.
"In the following week, the team will reassess and update all operational protocols, commands, and related items essential for executing the switch to backup hardware. They will then validate their processes against a high-fidelity simulator," explained NASA officials.
Chapter 2: Hubble's Legacy and Future Outlook
Launched in 1990, the Hubble Space Telescope has delivered over three decades of extraordinary insights into the universe. Despite facing these recent challenges, both the telescope and its instruments remain in excellent condition and are currently in a secure configuration. There is hope that Hubble will soon resume its exploration of the remarkable cosmos.
