On an upcoming servicing mission scheduled for August 2008, NASA plans to upgrade the Hubble telescope to be 90 times as powerful as it currently is. 90 times!
Two powerful new instruments will be installed on the mission. The Wide Field Camera 3 (WFC3) will allow Hubble to see fainter and more distant galaxies than anything it has seen before, shedding light on the early universe. This could allow Hubble to see galaxies so far away that we see them as they were just 400 million years after the big bang.
