Here is a recent post by NASA Astronaut John Grunsfeld on the "NOLS Share Your Leadership Story" web page.
From the International Space Station:
This space mission to the Hubble was by far the most complex and difficult of my expeditions to space. We spent over 3 years planning, preparing and training to make the repairs and upgrades to the telescope. The success of our mission can only be attributed to this preparation, and training, and more training. Everyone knew their role and strived for excellence. We knew we'd make mistakes, and planned for it. After all we're all human. The goal was to trap the mistakes early, resolve the issue and then to move on.
The satisfaction we have of leaving Hubble with more capability for science and exploration than it's ever had is huge. My entire crew is NOLS trained--starting with my WRW in '74, when Paul Petzoldt was in the lumberyard, to our Hubble Crew training by NOLS Pro, the NASA Sea Kayaking Leadership Expedition in Alaska in 2007.
Thanks, John Grunsfeld
