William Gerstenmaier is guest speaker for luncheon on first day of Wernher von Braun Memorial Symposium. William Gerstenmaier, associate administrator, Human Exploration and Operations at NASA Headquarters, shared an overview of NASA programs that are in the scope of human space exploration during his remarks. He discussed the vast landscape of NASA’s human space exploration missions and showed his love for the practical side of NASA’s work. "I’m always excited to see real hardware and speak with real engineers. That’s why I’m always glad to visit Marshall."

“Especially right now during the pandemic crisis, I love to occupy my mind. People say that they’re tired of being at home, but I don’t feel that. I practice yoga. I love decorating our house and working in the backyard during the summer time. If I don’t like where something is, I have to change it. That’s what I love. It’s the same thing with my work —I go outside the box to get ideas. I think about, how do I solve this? I apply the same skills to my creative passions and my current job. I create strategies for a better way of doing business for NASA. And I set the tone to keep me motivated and more productive.” NASA Senior Program Analyst, Jenny Acebron-Carlos, poses for a portrait at the Lincoln Memorial, Friday, Feb. 12, 2021 in Washington.
