This date in science: John Glenn first American to orbit Earth



February 20, 1962. John Glenn became the first American to orbit the Earth on this date. He made three turns around the planet before returning safely in his space capsule, which was called Friendship 7. He followed two Russian cosmonauts in making this early orbit of our planet: Yuri Gagarin ( April 1961) and Gherman Titov (August 1961).


While Glenn was in orbit, NASA controllers received an indication that the heat shield on his craft had come loose. They instructed Glenn not to jettison the rockets underneath the heat shield during re-entry, because the rockets might be able to hold the shield in place. Fortunately, the indication turned out to be a false alarm.


Glenn returned to space at age 77 aboard the space shuttle Discovery in 1995, making him the oldest person to fly in space. His mission’s primary scientific aim at that time was to study the effects of spaceflight on seniors.

Here's What John Glenn saw on February 20, 1962. Just 5 minutes and 44 seconds after launch, Glenn offered his first words about the view from his porthole: “This is Friendship 7. Can see clear back; a big cloud pattern way back across towards the Cape. Beautiful sight.” Three hours later, at the beginning of his third orbit, Glenn photographed this panoramic view of Florida from the Georgia border (right, under clouds) to just north of Cape Canaveral. His American homeland was 162 miles (260 kilometers) below. “I have the Cape in sight down there,” he noted to mission controllers. “It looks real fine from up here. I can see the whole state of Florida just laid out like on a map. Beautiful.” Image via NASA
