Hubble telescope has new lease on life after computer swap appears to fix glitch (sciencemag.org)

Article summary

The Hubble telescope has been fixed after a computer swap, extending its life beyond its initial planned mission. The telescope's hardware is 30 years old and has been operating in a harsh environment. The fix involved replacing a Power Control Unit, which was identified as the source of the problem. This repair is significant as Hubble provides unique scientific capabilities that complement other telescopes like the James Webb Telescope.

What commenters say

• The Hubble telescope's longevity is a testament to the ingenuity and quality of NASA's engineering and space exploration efforts.
• Robotic servicing of satellites like Hubble could be a viable option for future maintenance and repairs, potentially extending their lifespan.
• The development of general-purpose robots capable of servicing complex systems like Hubble is still in its infancy and faces significant technical challenges.
• Building a new telescope from scratch might be faster and cheaper than developing a robotic system to service an existing one like Hubble.
• The idea of using robots for satellite servicing is not new and has been explored in the past with projects like Robonaut.
• The use of robots in space exploration could potentially reduce the risks and costs associated with human missions.
• The concept of a robotic system that can service multiple types of satellites and systems is still far from reality and may require significant advances in artificial intelligence and robotics.
• The harsh environment of space and the complexity of systems like Hubble pose significant challenges to the development of robotic servicing capabilities.
