LeoStella, a joint venture between Thales Alenia Space and Spaceflight Inc, designs and manufactures small satellites for LEO constellations at scale.
ACTIVELeoStella is a joint venture between Thales Alenia Space and Spaceflight Inc. that designs and manufactures high-performance smallsats for LEO constellations at scale.
LeoStella is a joint venture between Thales Alenia Space and Spaceflight Industries (now BlackSky parent) established to design and mass-produce small satellites for low Earth orbit constellations. Based near Seattle, their production facility is optimized for building satellites at volume with consistent quality, supporting BlackSky's constellation as well as third-party customers. LeoStella combines Thales Alenia Space's heritage in satellite manufacturing with agile smallsat development practices, producing compact, capable spacecraft for Earth observation, communications, and other LEO mission profiles.
