Building the Foundation for a New Space Economy

Under a NASA Space Act Agreement, Northrop Grumman’s vision for a commercial free-flying space station in low Earth orbit (LEO) focuses on a delivering a safe, reliable and cost-effective solution that will continue the work of the International Space Station (ISS), enabling a smooth transition to commercial operations. Northrop Grumman envisions an accessible marketplace, optimized and tailored to support a variety of customers across multiple markets.

Borrowing from its proven design and ongoing human spaceflight and space operations program, Northrop Grumman’s commercial space station concept employs adaptable technology, centered on a modular design, to enable more affordable future civil and commercial missions. When paired with Northrop Grumman’s deep heritage with commercial spacecraft, the result will be a cost-efficient, and dependable design that supports multiple markets with room for growth, well-suited to aid in the creation and sustainment of a vibrant LEO economy.

Northrop Grumman’s concept for a commercial space station in LEO expands on its demonstrated and ongoing technical expertise in human spaceflight to create an adaptable destination and marketplace in space that can be customized to support the evolving needs of this new economy.

Preliminary design capabilities and features include, but are not limited to:


  • Crew capacity of up to four in initial configuration
  • Crew capacity of up to eight in second stage configuration
  • Up to 6 docking ports for visiting vehicles and future expansion of new capabilities
  • Science facilities, for example glovebox, cold stowage and incubators
  • Full crew services, including food, clothing, facilities, transport, training and entertainment

Turn-key Services NG and its Partners are developing plans for:

  • Tailored crew and payload training services
  • Launch and recovery/return services
  • Payload/science services, including delivery, facilities, power and data/communication
  • Tailored crew and payload training services
  • Launch and recovery/return services
  • External payload services that allow orientation of payloads with variety of boresights
  • Regularly scheduled crew and cargo services with proven providers
  • On-orbit power generation distributed at regulated 120V and 28V bus lines
  • Data interface support for multiple digital-serial and ethernet interfaces
  • Communication pathways from 300 Mbps to >1 Gbps downlink rate capability
  • Vibration isolation to support microgravity science payloads
  • Visual documentation services
