Sam O’Nella famous for his Sam O’Nella Academy Youtube channel gained over 1.3 million subscribers in three years thanks to his fun and informative videos that explain complex topics using simple illustrations.
In the video below titled Animals in Space: A Brief History, O’Nella talks about the animals that ended up in space at some point. “So the great zoo in the sky was first founded in 1947,” he begins, “when the U.S. launched a craft containing a bunch of fruit flies 68 miles in the air in order to see what kind of horrible mutants would get made from all the cosmic radiation up there.”
Learning that the insects were totally fine was the green light to send more animals to space.
