What STAR HARBOR does
STAR HARBOR is building a 53-acre spaceflight preparation and research campus in Lone Tree, Colorado, positioned as the world's first publicly accessible spaceflight preparation facility. The company integrates astronaut training, payload development and validation, aerospace medicine, and end-to-end mission support under three service pipelines: HUMANS TO ORBIT (H2O) for astronaut certification, health and medical systems, and human spaceflight services; LAB TO ORBIT (L2O) for payload technical development, testing, validation, and commercial brokerage for LEO destinations; and LAB TO LUNAR for lunar payload brokerage, integration, operations, and Lunar Terrain Vehicle training and operations.
The campus under construction includes a purpose-built suite of co-located facilities — a 4-million gallon neutral buoyancy tank, high-G centrifuge, hypobaric and hyperbaric chambers, a Boeing 767 for parabolic microgravity flight, a Bioastronautics Center, a full-service space medicine clinic, a Human Performance Center, payload testing environments, and a Mission Control Facility. Underlying technical capabilities are anchored in aerospace medicine and human systems integration rather than software or AI. The company is pre-revenue, with the physical campus still under construction, and pricing is bespoke and quote-based.
Revenue mechanics are sales-led enterprise engagement, with direct partnership cultivation, CEO-led networking, and consortium participation (Lockheed Martin Lunar Mobility Vehicle, Northrop Grumman CLD) as core go-to-market channels. Customer segments are commercial space providers, government agencies (NASA, FAA), and academic institutions (University of Colorado Anschutz Medical Campus). The company is founder-owned and led by CEO and Chairwoman Maraia Tanner, with a board and advisory bench that includes former Boeing CEO Dennis Muilenburg, former NASA astronaut Ron Garan, and a Medical Advisory Council of 30+ space medicine experts.

STAR HARBOR competitors and assessment
Company assessmentBroad incumbents
- Blue Origin: Operates astronaut training for New Shepard and is developing Orbital Reef with Sierra Space. A larger incumbent with overlapping astronaut training and CLD activities, though training is captive rather than commercial.
- SpaceX: Operates proprietary astronaut training for Crew Dragon missions and operates commercial payload services. The dominant incumbent in commercial human spaceflight; while it does not sell training externally, it sets the competitive benchmark.
Direct peers
- Zero-G Corporation: Operates parabolic microgravity flights for both training and public experience, a direct parallel to STAR HARBOR's planned Boeing 767 microgravity platform. Closest competitor in the public-facing microgravity training experience category.
- Sierra Space: Building the Dream Chaser spaceplane and LIFE habitat for commercial LEO. Comparable in commercial spaceflight infrastructure, human spaceflight support, and payload services for low-Earth orbit destinations.
- Vast Space: Developing commercial space station (Haven-1) with planned astronaut access. Comparable as a fellow CLD-prime ecosystem player that will need third-party training, payload integration, and human systems services.
- Axiom Space: Building commercial space station modules and operating private astronaut missions to the ISS. Direct comparable in commercial human spaceflight training, payload services, and private astronaut certification - the most analogous business model to STAR HARBOR.
- World View: Stratospheric balloon flight and space tourism company where former CEO Ron Garan was Chief Pilot. Directly comparable as a competing commercial spaceflight and training provider with overlapping talent network.
- Redwire Space: Provides payload integration, space infrastructure, and on-orbit services. Comparable on the payload services and space technology development side of STAR HARBOR's LAB TO ORBIT offering.
- Voyager Space: Parent of Nanoracks and major partner in commercial space station (Starlab) development. Highly comparable on payload services, commercial LEO infrastructure, and crew/training support for the CLD program.
Emerging players
- Bigelow Aerospace (legacy): Pioneered commercial inflatable space habitats (BEAM on ISS). Conceptually comparable as a commercial space infrastructure pioneer; though currently inactive, its legacy set the precedent for the CLD market STAR HARBOR is now serving.
