Amateurs are already pretty good at finding small objects in space. They’ve gotten to the point where they’re regularly finding the government’s über secret space projects as well. Nearly everything is cataloged and tracked through public databases feeding from government data feeds and amateur sleuthing to the point that nearly anyone with the right equipment can catch glimpses of satellites and other vehicles, to include the X-37b during operational flights. For those that don’t remember, the X-37b began as a NASA project to be a lifeboat for the ISS but was later consumed by the DoD as an autonomous spacecraft.
