'Symphony In The Stars' is the first of two dedicated missions on Electron to deploy a single spacecraft to a 650km circular Earth orbit for a confidential commercial customer. A second dedicated launch on Electron to meet those same mission requirements is scheduled for launch before the end of 2025. The payload has since been identified by USSF as EchoStar's Lyra-4, an EchoStar Lyra Block 1 satellite. It is a 4-satellite constellation that will deliver global Internet of Things (IoT), machine-to-machine (M2M) and other data services through S-band. EchoStar will operate the constellation from its Australian subsidiary, EchoStar Global.
LYRA-4 was lifted into orbit during the mission ‘Electron | Symphony In The Stars (EchoStar Lyra-4)’, on board a Electron space rocket.
The launch took place on June 28, 2025, 7:08 a.m. from Rocket Lab Launch Complex 1B.
