A group of apes is called a shrewdness; a group of ferrets is called a business; a group of small satellites is called a constellation. And Spire is the name of one shrewd business with a constellation of small satellites. More than 60 of its sats are up in orbit, collecting information about the weather, as well as the movements of ships and air traffic. Inside Spire’s Boulder office, a conference-room computer beams those satellites’ knowledge from space to a screen.
