This is a list of current and planned commercial space stations.
Current
editWhile commercial space flights have been flown to the International Space Station, there are currently no commercial space stations in operation.
Planned
editAxiom Segment/Axiom Station
editAxiom Orbital Segment or Axiom Segment are the planned components of the International Space Station (ISS) designed by Axiom Space for commercial space activities and space tourism uses. Axiom Space gained initial NASA approval for the venture in January 2020. This orbital segment is planned to be separated from the ISS to become a separate space station, Axiom Station, after deorbiting of the latter. It is unsure what launch vehicles will be used to launch these modules.
Up to three Axiom modules are planned to be attached to the International Space Station. The first module is expected to be launched no earlier than late 2026[1] and would dock to the forward port of Harmony, requiring relocation of Pressurized Mating Adapter (PMA-2) to any other ports on ISS like Harmony nadir. Axiom Space plans to attach up to two additional modules to its first core module, and send private astronauts to inhabit the modules.[2]
Axiom renderings illustrate how the three modules might attach to the ISS as they are berthed and relocated by the Mobile Servicing System using Canadarm2. Canadarm2 might also continue its operations on the Axiom Space Station after the retirement of ISS in the early 2030s.[3][4]
Orbital Reef
editOn October 25, 2021, Blue Origin announced that together with Sierra Space it would build a 'Mixed-use space business park' in LEO called Orbital Reef, to 'open multiple new markets in space, [and] provide anyone with the opportunity to establish their own address on orbit. [..it] will offer research, industrial, international, and commercial customers the cost competitive end-to-end services they need including space transportation and logistics, space habitation, equipment accommodation, and operations including onboard crew. The station will start operating in the second half of this decade..'[5] Further partners are Boeing, Redwire Space, Genesis Engineering Solutions, and Arizona State University.[6]
Starlab
editStarlab is the name given to the planned LEO space station designed by Nanoracks for commercial space activities uses. The station is expected to be launched in 2028.
The company released preliminary plans in October 2021, where the main structure of Starlab consisted of a large inflatable habitat to be built by Lockheed Martin and a metallic docking node. In 2023, the design changed to a metallic structure with Airbus Space as the main partner.[7]
The station is being designed to support 4 persons in 340 m3 of volume. The station also features a 60 kW power and propulsion element, a large robotic arm for servicing cargo and external payloads. The company has partnered with other companies to realise the project:[8]
- Nanoracks: Nanoracks owns and operates Starlab and GWC Science Park.
- Voyager Space: Voyager, the majority stakeholder in Nanoracks;
- Airbus: Airbus builds spacecraft systems. The company serves as the technical integrator for Starlab and will develop Starlab's habitat module. After launch, Airbus will operate the system under Nanoracks' leadership.
Haven-1
editIn May 2023, Vast announced that they had purchased a SpaceX Falcon 9 launch for the Haven-1 space station, targeted for launch as early as August 2025.[9]
Haven-2
editIn October 2024, Vast announced Haven-2, a planned successor to Haven-1. It's intended to be much larger than Haven-1, with modular assembly and the intention of replacing the International Space Station. The first module of Haven-2 is expected to be launched by SpaceX Starship in 2028, if the station is approved during the second phase of NASA's Commercial LEO Destinations program in 2026.[10]
Canceled
editBigelow Aerospace space station
editBigelow Aerospace proposed an expandable space station for commercial use. Air would have be pumped into the station to inflate each piece once they arrived on orbit. Bigelow ceased operations in 2020.
Northrop Grumman
edit
In December 2021, Northrop Grumman signed a Space Act Agreement with NASA under the Commercial Low-Earth Orbit Development program for $125.6 million to design a commercial free-flying space station in low Earth orbit (LEO).[11] Northrop Grumman had a web page describing their "vision for space-as-a-service" which "focuses on delivering an accessible, full-service commercial space station in Low-Earth Orbit (LEO) that will continue the work of the International Space Station (ISS), while expanding across multiple markets to provide optimized and tailored support for a new commercial economy."[12] Northrop Grumman was partnering with Rhodium Scientific on bio-tech and bio-pharma research in low-earth orbit.[13]
In October 2023, Northrop-Grumman announced that they would abandon the concept and instead join forces on Voyager's Starlab space station.[14]
