John Glenn lived a life filled with firsts.

After serving as a pilot in World War II and the Korean War, he became the first American to orbit the Earth in 1962 as a member of the Mercury 7, NASA's first class of astronauts.

In 1998, when he was 77 years old, he flew on board the space shuttle Discovery and became the oldest man to ever travel to space.

In between those major milestones, he didn't stray far from government work, although this phase of his career was a little more grounded -- from 1974 to 1999, he served as a U.S. senator for his home state of Ohio.

Glenn died at 95 this week, at the James Cancer Hospital at Ohio State University.

In a statement, President Obama said of the astronaut and public servant, "John always had the right stuff, inspiring generations of scientists, engineers and astronauts who will take us to Mars and beyond -- not just to visit, but to stay...The last of America's first astronauts has left us, but propelled by their example we know that our future here on Earth compels us to keep reaching for the heavens. On behalf of a grateful nation, Godspeed, John Glenn."
