The news of Glenn’s death had Americans around the country mourning the former senator who ventured into space multiple times and fought for his country during World War II and the Korean War.

Astronaut Mark Kelly took to Instagram to pay his respects for one of the founding fathers of American space travel, calling him "a real explorer with real guts."

Kelly said that working with Glenn "was like a rookie playing baseball alongside Babe Ruth or a kid getting music lessons while Mozart composed in the next room.”

He added: “He not only inspired us and a generation of explorers, but he also inspired our nation to set big goals that moved our space program and country forward.”

Glenn, who served in the U.S. Marine Corps., was mourned by the Marines on Twitter.

The Corps lost a legend today.
