Dr. Mae Jemison, the first African American woman astronaut in space, went out and bought The Overview Effect while training for spaceflight. But it didn't resonate with her the way it did with other astronauts. "When I read The Overview Effect, people started talking about their hearts connected to this planet. But my response when I went into space is that I was connected to everything," she says. "I felt much more connected to everything else in the universe, and sometimes on Earth I felt much more separate from the rest of the universe. I felt like I had as much right to be in space or in this universe as any speck of stardust. I was as eternal as that."
