Unofficial Re-stream

Watch live coverage as SpaceX launches a Falcon 9 rocket carrying 29 satellites for Elon Musk's Starlink internet service. Liftoff from Space Launch Complex 40 at Cape Canaveral Space Force Station is scheduled for Wednesday, March 4, during a launch window that opens at 5:52:20 a.m. EST (1052:20 UTC). The first-stage booster for this mission, 1080, launching for a 25th time time, will land on SpaceX's drone ship 'A Shortfall of Gravitas', stationed in the Atlantic Ocean, roughly 8.5 minutes after leaving the launch pad.

The mission, designated Starlink 10-40, will take a north-easterly trajectory on departure from Florida's Space Coast.

Our live coverage with commentary from Spaceflight Now's Will Robinson-Smith will start about one hour prior to launch.

Tranche 1 Transport Layer E is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites.

The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance.

Firefly Alpha's Flight 7 will be a test flight and return-To-Flight for the launch vehicle after its April 2025 launch failure. It will test and validate key systems ahead of Firefly’s Block II configuration upgrade on Flight 8 that’s designed to enhance reliability and manufacturability across the vehicle.

Flight 7 will be the last flown in Alpha’s current configuration and will test multiple Block II subsystems, including the in-house avionics and thermal improvements, to gain flight heritage and validate lessons learned ahead of the full configuration upgrade on Flight 8.
