Title: Firefly Aerospace's Alpha Rocket Fails, Sends Satellite Falling Into
Ocean

Link: https://science.slashdot.org/story/25/04/29/2...

Firefly Aerospace's sixth Alpha rocket launch failed on April 29, 2025, after
an upper-stage anomaly prevented a Lockheed Martin satellite demo from
reaching orbit. Both the stage and payload fell into the Pacific Ocean near
Antarctica. Space.com reports: The two-stage, 96.7-foot-tall (29.6 meters)
Alpha lifted off from California's Vandenberg Space Force Base this morning
(April 29), carrying a technology demonstration for aerospace giant Lockheed
Martin toward low Earth orbit (LEO). But the payload never got there. Alpha
suffered an anomaly shortly after its two stages separated, which led to the
loss of the nozzle extension for the upper stage's single Lightning engine.
This significantly reduced the engine's thrust, dooming the mission, Firefly
said in an update several hours after launch. Today's mission, which Firefly
called "Message in a Booster," was the first of up to 25 that the company
will conduct for Lockheed Martin over the next five years. The flight aimed
to send a satellite technology demonstrator to LEO. This demo payload "was
specifically built to showcase the company's pathfinding efforts for its LM
400 mid-sized, multi-mission satellite bus, and to demonstrate the space
vehicle's operational capabilities on orbit for potential customers," Firefly
wrote in a prelaunch mission description. "Initial indications showed Alpha's
upper stage reached 320 km [199 miles] in altitude. However, upon further
assessment, the team learned the upper stage did not reach orbital velocity,
and the stage and payload have now safely impacted the Pacific Ocean in a
cleared zone north of Antarctica," an update reads. "Firefly recognizes the
hard work that went into payload development and would like to thank our
mission partners at Lockheed Martin for their continued support," it
continues. "The team is working closely with our customers and the FAA
[Federal Aviation Administration] to conduct an investigation and determine
root cause of the anomaly. We will provide more information on our mission
page after the investigation is completed."
