Famed astronaut and former US Senator John Glenn has died at the age of 95, according to The Columbus Dispatch. Glenn had been hospitalized for the past week at Ohio State University Wexner Medical Center in Columbus.

Glenn is known for his February 1962 Friendship 7 mission, during which he became the first American to orbit the Earth. Four other people had been to space before him, two of which were Americans who had already performed suborbital flights. But there’s something to be said about going orbital. It requires a whole lot more speed and thrust to get into an orbit around Earth. His trip effectively paved the way for human exploration of space for the following decades.
