In 1995, NASA astronaut Dr. Bernard Harris became the first African American to perform a spacewalk, and he has spent more than 18 days in space. Today, he's the CEO of NMSI, the National Math and Science Initiative, which runs programs designed to boost the number of STEM teachers. We talked with Dr. Harris about his mission to bring in culturally responsive teaching in STEM, and we asked what it's like to go to space (and what space food really tastes like.)
