From the Document: "Regulators and policymakers are struggling to keep pace with small satellites, spacecraft the size of shoe boxes that are displacing school bus-sized satellites for many purposes. 'Smallsats,' as they are known, occupy low Earth orbit (LEO) at an altitude of between about 310 and 1,200 miles above Earth's surface. Many currently in orbit are about 10 centimeters wide and weigh less than 3 pounds. They have been used in government operations, but commercial companies are increasingly building and deploying them for communications, broadband internet, remote sensing, and Earth observation missions."
