Upcoming Spaceflights


Firefly Alpha Block 2 | QuickSounder

Firefly Aerospace | United States of America
Vandenberg SFB, CA, USA
TBD September, 2026
Status: To Be Determined
Mission:

QuickSounder is the first satellite mission of the Near Earth Orbit Network (NEON) program of the National Oceanic and Atmospheric Administration (NOAA), which aims to replace the current Joint Polar Satellite System (JPSS) series of polar orbit weather satellites. This pathfinder mission will demonstrate NOAA's ability to launch a small satellite within 3 years, flying a refurbished Advanced Technology Microwave Sounder (ATMS) instrument to polar orbit.

Firefly Alpha Block 2 | TacSat

Firefly Aerospace | United States of America
Vandenberg SFB, CA, USA
TBD December, 2026
Status: To Be Determined
Mission:

First of up to 25 launches of Low Earth Orbit technology demonstration satellites to be built and operated by Lockheed Martin. TacSat is an intelligence, surveillance and reconnaissance spacecraft with a mission to prove specialized sensing and communications capabilities on orbit. The satellite will participate in exercises that highlight cross-domain kill-web connectivity, enabling timely execution of tactical space missions. TacSat will host a proven Lockheed Martin infrared sensor on board that brings previously developed technology to space for the first time. This sensor produces high quality imagery and it can interface with federated Battle Management Command & Control (BMC2) combat systems to provide joint forces with a comprehensive view of threats. The satellite will also feature Lockheed Martin’s first 5G.MIL® payload on orbit. This provides cellular-like networking for military space assets, making satellite constellations more resilient. It also helps enable seamless connectivity with tools in the air, at sea and on land. Launch operation will also again demonstrate responsive space pre-launch operation capabilities.

Firefly Alpha Block 2 | INCUS

Firefly Aerospace | United States of America
Wallops Flight Facility, Virginia, USA
TBD December, 2027
Status: To Be Determined
Mission:

The Investigation of Convective Updrafts (INCUS) is a NASA Earth science mission led by Colorado State University that will investigate the behavior of tropical storms in order to better represent these storms in weather and climate models. It consists of 3 SmallSats flying in tight coordination to study why convective storms, heavy precipitation, and clouds occur exactly when and where they form. Each satellite will have a high frequency precipitation radar that observes rapid changes in convective cloud depth and intensities. 1 of the 3 satellites also will carry a microwave radiometer to provide the spatial content of the larger scale weather observed by the radars. By flying so closely together, the satellites will use the slight differences in when they make observations to apply a novel time-differencing approach to estimate the vertical transport of convective mass.
