    I am so sad to hear about the passing of my hero Jim Lovell. He was a great role model not only as an astronaut, but also as a person who exemplified a life well lived - both professionally and personally. He will be missed by many, Godspeed my friend.

    Seventeen years ago today I stepped outside of space shuttle Columbia for my first spacewalk on @NASAHubble, I experienced the beautiful view of our planet, and have thought about that day every day since.

    #otd in 1969 Neil Armstrong became the first person to walk on the moon - perhaps the greatest engineering and science accomplishment in history and the inspiration for me at age 6 to want to grow up to be an astronaut. Congratulations to all the thousands of people who made it

    Scariest moment of my life... today in 2009, @NASA instructed me to rip the handrail off @NASAHubble, to save STIS. #STS125

    #OTD in 1984 this amazing photo was taken of @NASA astronaut Bruce McCandless, the first person to go on a spacewalk without a tether. I asked Bruce what that felt like, he said that when he was far from the space shuttle he got really, really cold - he was one cool guy!
