The repairs, along with the addition of two new instruments, will make Hubble 90 times as powerful as it was after its flawed optics were corrected in 1993.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://space.newscientist.com/article/dn13160-upgraded-hubble-telescope-to-be-90-times-as-powerful.html?feedId=online-news_rss20"><P>The most challenging part of the mission will be to repair ACS and STIS.
