Days before he died Thursday at age 95, John Glenn, the first American to orbit the Earth, wrote a letter to another space enthusiast - Jeffrey P. Bezos - who has said watching the moon landing at age 5 was a seminal moment and one of the reasons he founded his space company, Blue Origin.
In the letter, which was presented to Bezos at an awards ceremony Thursday evening as part of the Smithsonian Magazine American Ingenuity Awards, Glenn wrote that in 1962, when he took his historic flight, "you were still two years from being born."
When Glenn returned to space in 1998 on a space shuttle mission at age 77, "you were already driven by a vision of space travel accessible not only to highly trained pilots and engineers and scientists, but to all of us," he wrote.
