Orbital transfer vehicles and Mars landers; Mira kick stage for last-mile satellite delivery.
A fully reusable launch vehicle with a novel second-stage recovery system, backed by leading VC firms.
Low-cost Daytona rocket for dedicated small-satellite launch, with vertically integrated satellite manufacturing.
Droid spacecraft for proximity operations, satellite servicing, and DARPA-funded debris management.
Jackal autonomous orbital vehicles and the Mosaic software platform for military space domain awareness.
Microwave radiometer satellites addressing data gaps in methane emissions and extreme weather.
Very large, low-cost satellite buses enabled by Starship-class payload capacity.
The largest space companies by valuation are SpaceX (~$2T market cap, NASDAQ: SPCX), Blue Origin, Northrop Grumman, Lockheed Martin, Boeing, Airbus Defence and Space, L3Harris Technologies, Raytheon (RTX), and Rocket Lab. Among startups and recent IPOs, Anduril (~$61B), Firefly Aerospace (Nasdaq: FLY), Sierra Space, Vast, and Relativity Space have raised or been valued at the most capital.
There are over 10,000 companies worldwide working in the space industry, ranging from multi-billion-dollar primes to early-stage startups. The commercial space sector (NewSpace) includes approximately 2,000+ venture-backed companies.
Space companies operate across the value chain: launch services (SpaceX, Rocket Lab, ULA), satellite manufacturing (Airbus, Maxar), Earth observation (Planet Labs, BlackSky), satellite communications (Starlink, OneWeb), space stations (Axiom, Vast), defense and national security, and more.
Public space companies can be bought as stocks (SPCX, RKLB, FLY, VOYG, HAWK, YSS, PL, BKSY, ASTS, RDW, IRDM). Space ETFs include ARKX, UFO, and ITA. Still-private companies like Blue Origin require accredited investor access through secondary markets or space-focused VC funds like Space Capital or Seraphim.
