NASA's latest shuttle launch is set for today at 2:01 PM EDT. The self-assessed "high risk" mission is an attempt to repair the Hubble telescope one final time.
According to the weather reports for Cape Canaveral, there's a 90 percent chance of favorable launch conditions.
The 11-day mission will include five spacewalks, at up to 7hours each. "This will be the most challenging servicing mission that's been faced by our astronauts in terms of the total amount of work," said mission manager, Preston Burch. If the mission succeeds, it will add up to five years onto the life of the 19-year-old telescope.
NASA is running a live feed of the launch all day with commentary over on its official site.
