Firefly Aerospace's launch of the Alpha Flight 7 was canceled on February 1, 2026, at Vandenberg Space Force Base in California due to high winds above FAA safety limits. The decision was confirmed at 00:15 Brasília time.

The mission, 'Stairway to Seven', aimed to test the rocket after a 10-month hiatus. The two-stage Alpha rocket, 29.6 meters tall, would have conducted its seventh flight, focusing on nominal performance of its stages, without carrying operational payloads.

Following the sixth flight failure, the FAA had authorized Alpha's return to flight in August 2025, but a subsequent test explosion caused further delays. Flight 7 is the last for the Block I configuration; Block II is planned for Flight 8.
