TAMPA, Fla. — Muon Space has raised $250 million to fuel the small satellite specialist’s push into larger, more powerful spacecraft and constellations.
The Mountain View, California-based manufacturer announced the closure of a Series C round Aug. 20 led by Eclipse Capital, which earlier this year co-led defense space startup True Anomaly’s $650 million Series D.
While Muon declined to comment on its valuation, a source said the funding valued it at $1.5 billion, adding to a surge of “space unicorns” crossing the $1 billion post-money threshold this year.
“As more industries rely on space-based intelligence, communications, and compute, this investment allows us to accelerate the next generation of space infrastructure,” Muon cofounder and CEO Jonny Dyer said in a news release announcing the Series C.
The five-year-old startup has deployed 11 satellites to date, including three this year for a low Earth orbit wildfire-monitoring system being developed in partnership with nonprofit Earth Fire Alliance.
