Space and Aerospace Marketplace and Services

About SpaceExcess

SpaceExcess has built an innovative marketplace for aerospace salvage and excess inventory, tailored to aerospace professionals, universities, and collectors.

The SpaceExcess website serves as a convenient portal for sales of spacecraft, launch vehicle hardware, components, production overruns, excess inventory, and cancelled space-program hardware. The site also provides the community with a specialized outlet for collectibles from past space missions.

In addition, SpaceExcess also maintains a substantial inventory from private collectors of historically significant space and aerospace components not shown on the website. These items are available for private sale.

Most importantly, SpaceExcess has structured its services in collaboration with experts in regulatory compliance -- including ITAR and EAR -- to help match sellers with qualified buyers.

Examples Include:

  • Aerospace Hardware
  • Satellites
  • Space & Aerospace Collectibes
  • Launch Accessories
  • Precision Connectors & Couplers
  • Waveguide Components
  • Engines & Turbines
  • Aerospace Prototypes
  • Manufacturing Overruns
  • Non-Controlled Mil-Spec Components


  • Optical Devices
  • Propellant Tanks
  • Rocket Stage Components
  • Bus Structures
  • Solar Arrays
  • Deployable Structures
  • Electronics
  • Jigs & Fixtures
  • Mission Manuals
  • Blueprints & Drawings
  • Space Media & Related Content


The founders of SpaceExcess come from different backgrounds, but they share the same passion for space exploration, the commercial space industry, and anything related to aerospace in general. They met through a network of aerospace research organizations, where they each served in various management capacities.

In 2016, Bill Cress realized that there was no existing online marketplace for the entire spectrum of space and aerospace surplus, so he approached his co-founders about creating this unique service to the aerospace industry.

The SpaceExcess site launched in 2017, and much of the following year was spent scouring the country for aerospace inventory suitable for the site. This turned up individuals and businesses with remarkable collections from the Apollo and Shuttle programs, as well as manufacturers with new, never-used inventory from production overruns.

The SpaceExcess website is attracting a growing audience of buyers and sellers of aerospace hardware and collectibles.
