Muon Space unveils MuSat XL platform with Hubble Network as first customer
Questions and answers:
What is the MuSat XL platform? Muon Space’s MuSat XL is a high-performance, 500-kilogram-class satellite platform designed for demanding next-generation low Earth orbit missions, offering enhanced power, agility, and integration flexibility.
Who is the first customer for the MuSat XL platform? Hubble Network in Seattle is the first customer, using MuSat XL to build its satellite-powered Bluetooth network.
What are the key capabilities of MuSat XL? The platform features over 1 kilowatt of payload power, high-bandwidth low-latency communications, optical crosslink networking with more than 5 terabytes per day of downlink capacity, flexible payload integration, and precise, agile pointing for advanced sensors and communications.
MOUNTAIN VIEW, Calif. - Muon Space in Mountain View, Calif., introduced its new satellite platform, the MuSat XL, a 500-kilogram-class spacecraft designed for next-generation low Earth orbit missions. The company also named its first customer for the platform: Hubble Network in Seattle, which is developing a satellite-powered Bluetooth network.
The MuSat XL builds on Muon’s Halo technology stack, adding more payload power, larger apertures, greater agility, and expanded integration flexibility for Earth observation and telecommunications missions. It supports multi-payload operations, extremely high data throughput, high-performance intersatellite networking, and advanced attitude control and pointing for precise targeting. These capabilities are aimed at both commercial and national security customers.
Hubble, which in 2024 established the first direct Bluetooth link to a satellite, will use the MuSat XL to deploy a next-generation payload with a phased-array antenna and a receiver 20 times more powerful than its CubeSat version. The system will detect Bluetooth signals at 30 times lower power.

Two MuSat XL satellites will initially provide a 12-hour global revisit time, with scalability for faster coverage. The Hubble network is aimed at logistics, infrastructure, defense, and consumer applications.
Key capabilities
The MuSat XL’s key capabilities include more than 1 kilowatt of orbit-average payload power to support advanced sensors, phased arrays, and edge computing; seamless internet-standards-based high-bandwidth, low-latency communications; optical crosslink networking with over 5 terabytes per day of downlink capacity for near real-time operations; a flexible PayloadCore architecture enabling rapid payload hardware and software integration; and precise, stable, and agile pointing optimized for demanding EO and RF payloads.
Muon Space says early adoption by Hubble reflects a broader industry shift toward platforms offering high capability, operational autonomy, and long mission life at commercial scale.
