"Piers devoted his life to saving the planet," NASA Administrator Charles Bolden said in a statement. "His legacy will be one not only of urgency that the climate is warming but also of hope that we can yet improve humanity's stewardship of this planet."
"It's been a very difficult two years, and I can't imagine what those of you in the Orbital team went through. I can't imagine how long you were holding your breath tonight," Bolden told the launch control crowd. "But you know, we made it and that's what's all important."
