Firefly Aerospace is an emerging player in the small satellite launch market. Its Firefly Alpha rocket is designed to carry payloads of up to 1,000 kg to low Earth orbit (LEO). Similar to Rocket Lab’s Electron rocket, the Firefly Alpha is constructed entirely from carbon composites. However, it is larger and capable of delivering a heavier payload. A notable feature of the Alpha is its use of a tap-off cycle engine, a design that has not previously achieved orbital flight.
Here’s a comparison of the Firefly Alpha and Electron rockets:
| Rocket | Height [m] | Diameter [m] | Payload to SSO [kg] | Cost per Launch |
|---|---|---|---|---|
| Firefly Alpha | 29 | 1.8 | 630 | ~ $15 - $18 million |
| Electron | 18 | 1.2 | 200 | ~ $8 million |
As a relatively new entrant in the aerospace industry, Firefly has experienced both setbacks and successes. Flights 3 and 5 were completed successfully, and the company aims to build on this progress with its next mission.
Blue Ghost Mission 1
In addition to its rocket program, Firefly Aerospace developed the Blue Ghost lunar lander. The spacecraft launched on January 15, 2025, and successfully landed on the Moon on March 2, 2025, marking a significant milestone for the company.
For more details on the lunar program, Ellie in Space provided an inside look in January 2023: Firefly Aerospace Behind the Scenes Moon Lander Testing.

The upcoming Firefly Alpha launch will be another opportunity for the company to demonstrate its capabilities in the competitive space industry.
