Think your daily commute is extreme? Then you may not have heard about two trips made by chemist, engineer and NASA astronaut Leland Melvin in 2008 and 2009: from Earth to the International Space Station and back. When it was time for his official portrait to be taken at Houston’s Johnson Space Center in 2009, Melvin was determined to have two of his biggest fans in the picture with him: his rescue dogs, Jake and Scout. Since NASA’s a dog-free workplace, getting them into the building required some fancy footwork. Once inside and dressed for the occasion in his orange spacesuit, Melvin was joyfully mobbed by his dogs, the photographer started shooting and the rest is viral history. Later, when asked about the photograph, Melvin said, “They were my boys. … It changed my life having those two dogs.” Read about Melvin’s inspirational career in his new memoir, Chasing Space, available in adult and young readers’ editions.
