Firefly Alpha

Firefly Alpha is designed to address the needs of the burgeoning small–satellite market. At a dedicated mission price of $15M, Alpha combines the highest payload performance with the lowest cost per kilogram to orbit in its vehicle class. Capable of delivering 1 metric ton to Low Earth Orbit (LEO) and 630 kg to the highly desirable 500 km Sun–Synchronous Orbit (SSO), Alpha will provide launch options for both full vehicle and ride share customers.

Alpha will launch twice per month, a launch cadence that will enable customers to fly according to their schedule and to the orbit they desire.
