SpaceX has launched thousands of its Starlink satellites into low-Earth orbit

Every launched batch of satellites contains roughly 60 of the desk-sized gadgets. The batch is released at random into an initial orbit, and it takes time for them to naturally spread out enough before operators begin unfolding their antennae.

The Teacher in Space program was launched in 1984 to highlight spaceflight in US classrooms
