HST SM4: ACS Repair: The Challenge to Fix Hubbles Best Survey Camera

The Hubble Space Telescope Servicing Mission 4 (HST SM4) included the repair and upgrade of the Advanced Camera for Surveys (ACS), which was one of Hubble's primary instruments for capturing stunning images of the cosmos. The ACS had developed technical issues, and the mission aimed to restore its functionality to continue its vital role in astronomical observations.

During SM4, astronauts faced the challenge of fixing the ACS, a task that required precise and delicate work in the weightless environment of space. They had to replace a faulty power supply board and install a new cooling system to address the instrument's overheating problem. This repair was crucial as the ACS played a significant role in many of Hubble's groundbreaking discoveries and contributed to its reputation as one of the most important astronomical observatories in history.

Ultimately, the successful repair of the ACS during HST SM4 extended Hubble's scientific capabilities, allowing it to continue capturing breathtaking images and conducting cutting-edge research in the field of astronomy.
