Astronaut John Glenn, the first American to orbit the earth, has died. Glenn was 95. He was admitted to the James Cancer Hospital at Ohio State University more than a week ago. John Glenn was the last surviving member of a group known as "the Mercury Seven," test pilots who, in 1959, were chosen to become America’s first astronauts. President Barack Obama released a statement about Glenn's death. Our nation has lost an icon and Michelle and I have lost a friend, he said. He praised Glenn for a lifetime of breaking barriers, including setting a transcontinental speed record and becoming the oldest man ever to go into space. He served as a military pilot in World War II and the Korean conflict. Then, he served as a test pilot on military airplanes.
