The Hubble Space Telescope, a collaborative effort involving scientists from 13 countries, faced initial challenges due to a flaw in its primary mirror. This flaw prevented the telescope from focusing properly, leading to unclear images. The solution involved installing corrective optics, known as COSTAR, which allowed Hubble to capture sharp images. The repair mission in 1993 was successful, enabling Hubble to observe space 10 billion light-years away, significantly advancing our understanding of the universe.
