About this Episode
On February 20th in the world of astronomy, one of the most exciting events occurred back in 1962. On this date, astronaut John Glenn became the first American to orbit the Earth aboard the Mercury spacecraft Friendship 7.
Picture this: It's the height of the Space Race between the United States and the Soviet Union. The Americans are playing catch-up after the Soviets successfully launched Yuri Gagarin into orbit less than a year earlier. The pressure is on, and all eyes are on John Glenn as he climbs into the tiny Mercury capsule perched atop an Atlas rocket.
At 9:47 a.m. EST, the engines ignite, and Friendship 7 lifts off from Cape Canaveral, Florida. Glenn is launched into space, and for the next 4 hours and 55 minutes, he circles the globe three times, reaching speeds of more than 17,000 miles per hour.
During his historic flight, Glenn conducted various scientific experiments and made observations. He noted the "fireflies" - later identified as ice crystals from the spacecraft's exhaust - and became the first person to eat in space (he ate applesauce from a tube, in case you're wondering about the menu).
The mission wasn't without its nail-biting moments. A faulty sensor indicated that the heat shield might be loose, causing concern about whether Glenn would survive re-entry. Mission Control decided not to jettison the retrorocket package after firing, hoping it would help hold the heat shield in place. Spoiler alert: It worked!
Glenn splashed down safely in the Atlantic Ocean, and upon his return, he was hailed as a national hero. His orbital flight marked a significant milestone in the U.S. space program and helped boost American morale during the Cold War.
So, on this day in astronomy history, we celebrate the courage of John Glenn and the dawn of American orbital spaceflight. It's a reminder that sometimes, to reach for the stars, you need a brave soul, a tin can, and a whole lot of rocket fuel!
