The Hubble was Almost a $15B Disaster

The Hubble Space Telescope, launched in 1990, faced initial challenges due to a flawed mirror. However, a series of servicing missions, starting in 1993, corrected these issues and extended Hubble's operational life. These missions involved complex spacewalks and innovative solutions, such as the installation of corrective optics. Despite the retirement of the space shuttles, Hubble continues to operate, but it faces eventual deorbiting between 2028 and 2040. The telescope's legacy includes significant scientific achievements and breathtaking images, made possible by its serviceability and the dedication of spacewalking astronauts.
