Smallsat
A smallsat is a miniature satellite, typically weighing less than 500 kg, designed for specific missions and often launched in constellations.

TECHNICAL DEFINITION
A Smallsat is a class of artificial satellites with a mass generally below 500 kg, encompassing categories like nanosatellites and microsatellites, designed for cost-effective, specialized missions and often deployed in large constellations.
BACKGROUND
Firefly Aerospace Blue Ghost, or simply Blue Ghost, is a class of lunar landers designed and manufactured by the American company Firefly Aerospace. Firefly builds and operates Blue Ghost landers to deliver small payloads to the surface of the Moon. The first Blue Ghost mission was launched in January, 2025. It successfully landed on the Moon on March 2, 2025. The landers are named after the firefly species Phausis reticulata, known as blue ghosts.
