The first American to orbit the Earth has died. John Glenn was the last surviving member of the original Mercury astronauts. He would later have a long political career as a U.S. senator, but that didn't stop his pioneering ways.
Glenn made history a second time in 1998, when he flew aboard the shuttle Discovery to become the oldest person to fly in space.
Glenn was 95 when he died; he had been hospitalized in an Ohio State University medical center in Columbus since last week.
