Tentatively id'd as LC37 (Saturn 1 vehicles) in the foreground and LC34 (also Saturn 1) in the background. A modern Google Earth image shows the pattern of crossing roads between the pads as visible in the screenshot. There also appears to be a Mobile Support Structure parked at the foreground pad. Seen here in an image from the Pad 37 Fact Sheet Pad 34 ...

Partial answer: I have a different contender: The LES-5 satellite, launched in 1967, was an early experiment in satellite-based communications broadcasting continuously since it was launched in 1967. It was decommissioned and placed in a “graveyard orbit” in 1972. https://www.popularmechanics.com/space/satellites/a32293223/les-5-satellite/ It became ...

On 29 July 2021 at 11:34 am Houston time, after having docked earlier at 8:30 am CT (13:30 UTC), the Nauka Multipurpose Laboratory Module (Upgrade) unexpectedly fired its movement thrusters, and did so for a good 45 minutes.

Depending on exactly what you want, I've found two plausible candidates. Luna 3 was (briefly) in a highly elliptical orbit in 1959. It spent at least a few months in space, and had an orbital period of ~360 hours. It was assumed to have burnt up in the atmosphere in 1960, so it must have made a few orbits in that time. Given that the perigee was quite low, ...

From the information on these websites 1, 2 & 3 (sorry but 3 is in Dutch - the electronic schematic diagrams in 2 & 3 match), the radio transmitter for Sputnik 1 used electronic tubes/valves, capacitors, variable capacitors and resistors. All "readily" available electronic components in 1957. It appears the tubes used in the radio ...
