Glenn died yesterday at age 95.

In 1962, Glenn became the first U.S. astronaut to orbit the Earth, and he later served 24 years in the Senate.

After Tuesday’s spectacular Space Shuttle Discovery flight over the region, thousands traveled to the Udvar-Hazy Center yesterday to welcome the shuttle and say goodbye to the Enterprise.

One of the most coveted tickets of the year for space fans to get their hands on is to the annual John H. Glenn Lecture at the Smithsonian National Air & Space Museum. This year, the series took a step back to the very beginning with the lecture’s namesake, Senator John Glenn and his fellow Mercury astronaut Commander Scott Carpenter, who spoke to the packed IMAX theater about the nascent steps of the American space program.
