NASA is about to launch six new next-generation Earth-observing small satellites — some as small as a loaf of bread. These tiny spacecraft are helping to foster creative and cost-effective approaches to studying our planet. This page contains a short overview video as well as a series of conceptual animations of small sats being launched, deployed, in orbit over the Earth collecting data, and in comparison in size to both a person and a traditional large satellite. Note: While these animations are based on real satellite models, they are intended to be generic and not perfectly descriptive of any particular small sat mission.
