Pixxel Firefly-4 (FFLY-4) is the first satellite in the second launch batch of Pixxel's Firefly Phase 1 hyperspectral constellation. It was launched on 26 August 2025 alongside Firefly-5 and Firefly-6 aboard a SpaceX Falcon 9 (NAOS mission) from Vandenberg SFB.^[1] The satellite operates in a Sun-synchronous orbit at approximately 550 km altitude, 97.65-degree inclination, with a 10:00-11:00 AM local solar time equator crossing.^[2]

The Firefly hyperspectral imager covers a spectral range cited as 450-900 nm by the operator^[2] and 470-850 nm by eoPortal^[3]; the operator-published figure is used here. Spatial resolution is 5 m, swath width 40 km, and single-satellite revisit is 17 days, consistent with the batch-1 specification per the operator press release.^[1]^[2] With all six Phase 1 satellites operational, the constellation achieves approximately 24-hour global revisit.^[2]

Firefly-4 has a mass of approximately 60 kg and is built on Pixxel's proprietary Firefly Bus. Orbital phasing configuration of the batch-2 satellites relative to batch-1 to achieve the full-constellation revisit cadence had not been publicly confirmed as of the research date (2026-05-24).^[1] No per-satellite capability or orbital differences within the batch-2 group have been reported.
