Orbital Reef is an under development low Earth orbit (LEO) space station being designed by Blue Origin and Sierra Nevada Corporation's Sierra Space for commercial space activities and space tourism uses. Blue Origin has referred to it as a "mixed-use business park".[1] The companies released preliminary concepts for the station on 25 October 2021. The station is being designed to support 10 persons in 830 m3 of volume.[2] As of March 2022[update], the station was projected to be operational by 2027.[3]
Blue Origin and Sierra Space partnered with several other companies and institutions to submit the 2021 proposal:[4][5]
On 2 December 2021, NASA announced it had selected Blue Origin as one of three companies to develop concept designs of space stations and other commercial destinations in space. Blue Origin was awarded $130 million.[9]
The contract with Blue was one of three funded Space Act Agreements (SAA) that NASA issued for the first phase of its Commercial LEO Destinations program (CLD).[10] Space Act Agreements provide limited funding for specific milestones to be achieved by the companies, and are distinct from more widely used Federal Acquisition Regulation FAR contracts used in most legacy NASA space programs, where NASA owns responsibility for both the design and the program requirements. The 2021 contract with Blue was just the first phase of two by which NASA is aiming to maintain an uninterrupted U.S. presence in low-Earth orbit by transitioning from the International Space Station to other platforms.[11][needs update]
In June 2023, ISRO chairman S Somanath told the Times of India that Blue Origin is “very keen” on considering using an Indian rocket as a crew capsule to service its proposed space station Orbital Reef in low-Earth orbit as a part of commercial ventures proposed by ISRO before the launch of the planned Indian Space Station .[12]
By October 2023, NASA reported they had paid out only US$24 million of the $130 million contract for completion of specific milestones. Also in early October, issues between Sierra Space and Blue Origin became public, and CNBC reported that the Orbital Reef website had not been updated in over a year, and that no hiring for the project is currently being done, as both companies have other larger space projects that are higher priorities for them. CNBC also reported that the two partners on the project may go their separate ways.[10] However, after talks between the companies, both companies tweeted on their Twitter accounts on 10 October that they were continuing to work with each other on the contract deliverables for Phase 1.[13]
In March 2024, NASA reported that Blue Origin had passed 4 test milestones relating to Orbital Reef.[14] More critical testing was reported to occur in Summer 2024.[15]
Orbital Reef’s design is reported to be modular in nature, to provide the greatest amount of customization and compatibility. It will reportedly be designed to accept docking from almost every in operation spacecraft like SpaceX Dragon 2, Soyuz (spacecraft), Dream Chaser, and Boeing Starliner
The initial modules will be the: LIFE, Node, Core, and Research Modules.[16]
