Astronaut David Wolf signs a memento for a student at Howard A. Doolin Middle School Miami.

After his presentation, astronaut David Wolf signs a memento for a student at Howard A. Doolin Middle School, Miami, Fla. The school is one of 100 taking part in the NASA Explorer Schools (NES) program. Center Director Jim Kennedy and Wolf visited the school to share America’s new vision for space exploration with the next generation of explorers. They talked with students about our destiny as explorers, NASA’s stepping stone approach to exploring Earth, the Moon, Mars and beyond, how space impacts our lives, and how people and machines rely on each other in space.
