Spire

In 2014, commercial company Spire Global inaugurated the Lemur project with the launch of the Low Earth Multi-Use Receiver-1 (Lemur-1) prototype satellite on a Soyuz Rocket. The main objective of the mission was to demonstrate the satellite platform and support systems. Lemur-2 is a constellation of nano-satellites with 3U CubeSat platforms, designed to maintain up to 175 flight units. The program began in 2015 with the launch of four Lemur-2 nanosatellites, and a total of 156 flight units have been launched as of May 2022. Lemur-2 images are used to track maritime, aviation, and weather activity from space.
