The world’s oldest flying satellite

Link here. It also happens to have been the fourth ever launched, and the second U.S. satellite, Vanguard 1.

Thanks to Kirk for reminding me that Vanguard 1 was not the first U.S. satellite, and was actually the fourth launched, not the second. All I needed to do to avoid the error was read my own Chronological Encyclopedia, but I was too lazy to do that, even though it is on my desk. Duh.
