The 19-year-old Hubble Space Telescope has yielded stunning images and a remarkable scientific legacy -- revealing new insight into the age of the universe, black holes and the role of "dark energy" in our expanding universe. University of Washington alum Gregory Johnson piloted the space shuttle Atlantis for the final service mission to Hubble. Imagine the extreme challenges of launching the shuttle 358 miles into space, capturing the huge telescope and making tricky repairs during five spacewalks. Johnson takes us on a thrilling journey into space and inside the final mission to Hubble.
