Grit & Grace: Astronaut Melvin Leland

NASA astronaut Leland Melvin is one of just over 550 people ever to travel to space, but his path into orbit sets him apart. "My mother gave me a chemistry set that was not OSHA-certified, age inappropriate, and I created an explosion in her living room and that activated my brain to be a scientist," Melvin said Thursday on "CBS This Morning."Asked how he achieved such success in his career, Melvin, who was a crew member of Space Shuttle Atlantis that launched into space in 2008, responded: "There was a lot of people that had my back when I failed. My mother and father said you can do anything you put your mind to."
