Unofficial Re-stream

Watch live coverage as SpaceX launches a Falcon 9 rocket carrying 29 satellites for the company's Starlink internet service. Liftoff from Space Launch Complex 40 at Cape Canaveral Space Force Station is scheduled for Thursday, June 4 at 6:26 a.m. EDT (1026 UTC). The first-stage booster, 1090, launching for a 12th 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 10-43, 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.

Isar Aerospace Launches the "Onward and Upward" Mission

The Globalstar global mobile communications network offers global, digital real time voice, data and fax services via its Low Earth Orbit satellite constellation. The constellation operates in a 1410 km orbit inclined at 52 degrees.

In early 2022, Globalstar contracted with MDA for the construction of 17 new 2nd generation refresh satellites to replenish the existing constellation. Rocket Lab is sub-contracted to build the satellites' buses and the launch dispensers.

Tranche 1 Transport Layer A 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.

This launch carries 21 satellites manufactured by Northrop Grumman.
