Spaceflight Industries announced Tuesday it has raised $150 million to fund development of its BlackSky constellation. Spaceflight said that Thales Alenia Space and Telespazio would take minority stakes in the company as part of a partnership announced last September. Mitsui and Co. Ltd. as well as existing investors are also contributing to the Series C round. Spaceflight and Thales Alenia will establish a joint venture called LeoStella LLC to manufacture satellites, starting with a set of 20 Earth-imaging satellites for the BlackSky constellation. That constellation, which will ultimately have 60 satellites, is designed to provide imagery at a resolution of one meter with multiple revisits per day.
