"Space Down to Earth” is a circa 1970 NASA education film that explores how science impacts not only the exploration of space but also life on Earth. The color film begins with “sounds” from space - signals from satellites orbiting Earth - each of which have their own signature, or tone. Such application satellites serve many different functions, we are told, including weather, communications, and Earth resources. Beginning at mark 01:45, the narrator explains how satellites such as Nimbus and TIROS track weather conditions around the globe, including hurricanes, as we see scenes from 1969’s Hurricane Camille - a catastrophic Category 5 hurricane that struck the Gulf Coast of the United States. (TIROS, we’re told at mark 06:00, also carries equipment that can help spot solar flares). Satellites are also used in communications, we’re told starting at mark 09:30, with those communication satellites doing everything from assisting in telephone calls to providing cable television service. At mark 10:26 we hear the voice of President Dwight D. Eisenhower transmitted in 1960 as a part of Project Echo, a metallic balloon satellite. We also see visit to Mexico City by Pope Paul VI (mark 11:27) and of course images of Neil Armstrong and Buzz Aldrin on the lunar surface as part of the Apollo 11 mission (mark 11:32), and the crew of Apollo 13 (mark 11:48) after they narrowly escaped death and returned to Earth. Communication satellites are also used to aid aircraft and other transportation areas (mark 15:20), as we see jets taxi down the runway. By mark 19:50, the film focuses on the use of satellites on natural resources such as oceans and other waterways and how they are impacted by pollution. Satellites can also track a variety of geographic features and compare the data for any environmental changes. As it approaches its conclusion, the film teases Skylab (mark 24:53), a United States space station. Still a few years away from launch at the time of the film, the film interviews astronaut William Lenoir at mark 25:13. (Lenoir had hoped to fly on Skylab but only served as a member of a back-up crew on two missions). In his interview, he touts the importance of satellites and their benefits in studying the planet’s resources.

These videos are amazing certainly a lot better than most content you can watch these days
As a kid I had a radio that picked up these signals, I would sit for hours listening to the transmission of blips... yes I was a weird child.
nah, you're not. It's anomalous sound. We're genetically tuned to pay attention to unnatural or 'different' things, ESPECIALLY related to noise! The more the caveman who paid attention to the rustling noise around the outside of the cave, the more likely he was to have children who look and ACT like him, and when multiplied over species to sub-species to sapiens (us) through tens of thousands of generations, an anomalous sound listing vigil is absolutely not weird at all.
(and no, I'm not trolling)
There was a film that was once on YT that was the preliminary science report derived from the samples of Apollo's 11 & 12. Any chance that we can have that film uploaded once again?
