Being low cost, multiple nano-satellites can be launched into low Earth orbit. The satellites in these constellations pass over a specific geographic area more frequently than single, big-satellite missions. This makes it possible for nano-satellites to be used for rapid responses to disasters, or to gather timely information relating to tele-medicine, environmental management and asset tracking. They will soon even reach to other planets.
