Secret Satellite -- Засекреченный спутник [СУБТИТРЫ]
Sputnik caught us flat-footed, but we jumped in with both feet and embarked on a plan to put our own satellites in orbit. While the Russians were mostly doing it for propaganda purposes, putting dogs and monkeys into orbit, we were trying to do something useful by putting cameras into orbit.
This video is almost an hour long, but it's pretty great, if you have any interest is this sort of thing.
The Russians had their own spy satellites starting in 1961.
The first American Corona satellite went up in 1959.
