Why We Can’t Rule Out Alien Spaceships in Earth’s Atmosphere (Yet) To help find out, in 2022 NASA commissioned an independent study to determine whether current satellites and surveillance systems have sufficient sampling depth to detect “unidentified anomalous phenomena,” or UAPs (government talk for what could be alien spaceships). The researchers’ conclusions: NASA’s fleet of Earth-observing satellites collect the most data within the Earth system, yet they typically lack the spatial resolution to detect relatively small objects such as UAP....
Commercial satellite constellations provide imagery at sub- to several-meter spatial resolution, which is well-matched to the typical spatial scales of known UAP.... The limitation on this data is that at any given time most of the Earth’s surface is not covered by commercial satellites at high resolution—for a particular UAP event, we will need to be fortunate to obtain high-resolution observations from space.
It seems that Earth’s atmosphere is unintuitively large, just as microorganisms are unintuitively small. While the atmosphere is so transparent and so close, we do not have a complete grasp of everything inside it. Consider that the average depth of Earth’s oceans is 2.3 miles, while the atmosphere extends up to about 6,200 miles, where it gradually transitions into space.
We don’t really see a lot of what happens in our own atmosphere.
