My official NASA photo, to support the heavy spacesuit I am actually sitting on a custom made stool.

In the suit room at KSC on launch morning, felt like Christmas morning when I was a kid, total joy.

The first spacewalk of my career, task #1 – get your picture taken!

Peeking into the aft flight deck of the space shuttle to see what was going on inside.

Changing out the Reaction Wheels on the Hubble Space Telescope with my spacewalking buddy Jim Newman, teamwork is crucial during a spacewalk.

Setting up safety tethers for my 3rd spacewalk, need to have those set up properly before we start our day of work.

Last moments of my final spacewalk, one last look at our magnificent Earth from outside of the spacecraft.
