Real Space – Every Space Station Size Comparison

An evening pause: Some quick visual space station history. Note how almost all the non-U.S. stations are essentially assembled using revisions of the same early Soviet-era modules. Note too how the future private stations are all very different from each other. The contrast illustrates the difference between what you get when governments control everything, and when competition and freedom rule.

NASA awards more money to two private space station proposals

Because Northrop Grumman has dropped its plans to build its own private space station, joining instead the Starlab station consortium led by Voyager Space, NASA has been able to shift the funding planned for Northrop Grumman’s station to two other two private space station projects.

Voyager Space’s Starlab station development will receive an additional $57.5 million from NASA, which brings NASA’s total funding for Starlab so far to $217.5 million, the space agency said.

…The Orbital Reef space station of Blue Origin and Sierra Space is receiving an additional $42 million, bringing that project’s total NASA funding so far to $172 million.

NASA says the extra money will help both consortiums meet their schedules.

A third private station, Axiom, also under development in partnership with NASA, plans to dock its initial modules to ISS, and then undock when completed to fly free.

A fourth American private space station is also being built, but independent of NASA entirely. The company, VAST, has teamed up with SpaceX to launch its first modules on Starship/Superheavy, followed by at least two manned missions.

NASA updates status of three private space stations

NASA today posted a short update of the development status for the three private space stations for which it has signed contracts.

Not surprisingly, Axiom’s station appears to be the most advanced.

Axiom Space, which holds a firm-fixed price, indefinite-delivery, indefinite-quantity contract with NASA, is on schedule to launch and attach its first module, named Axiom Hab One, to the International Space Station in 2026. A total of four modules are planned for the Axiom Commercial Segment attached to the station. After the space station’s retirement, the Axiom Commercial Segment will separate and become a free-flying commercial destination named Axiom Station.

With the remaining two stations, Starlab and Orbital Reef, the update provided no schedule information. While both Starlab, being built by a consortium led by Voyager Space, and Orbital Reef, being built by a consortium led by Blue Origin, appear to be making progess, the former appears to be accomplishing more than the latter, though that impression could simply be what NASA decided to report. For example, in describing the work being done on Orbital Reef, NASA chose for some reason to say nothing about the testing Sierra Space has been doing to test the inflatible module planned for the station. By leaving that out it makes it appear as if less has been done in developing that station.

These are not the only private space stations being proposed, only the ones that have contracts with NASA. A fourth station, Vast, is being built using funding from private sources, and is partnering with SpaceX.

NASA awards company contract to develop new advanced solar panels

NASA has awarded the solar panel company Solestial its second development contract, with both contracts worth more than one million dollars, to develop new advanced solar panels for use on future commercial space stations.

The 18-month SBIR Phase II contract will provide funds to support development of next generation, 50-kilowatt (kW) class solar array wings. Solestial’s silicon solar blanket technology will allow for arrays larger than any ever built, while also maintaining lower mass and competitive efficiency. The array will be developed in collaboration with Opterus Research & Development, who will develop a low-cost, novel deployment system for Solestial’s ultrathin, flexible, silicon solar blankets.

These blankets will be an upgrade from the new panels presently being deployed on ISS, that unroll like a blanket rather than unfold like hard panels. The design is lighter weight, easier to deploy, and cheaper. It will thus become a valuable product that every private space station will want to buy.

Voyager Space partners with Airbus to build its Starlab space station

Voyager Space, one of the three companies with a contract from NASA to develop a commercial private space station, has now signed a partnership agreement with the European aerospace company Airbus to work together to build its Starlab space station.

The companies announced Aug. 2 the creation of a joint venture, also called Starlab, that will be responsible for the development and operation of the station. The joint venture builds upon an agreement announced in January where Voyager selected Airbus to provide technical support for the proposed station.

“This transatlantic venture with footprints on both sides of the ocean aligns the interests of both ourselves and Voyager and our respective space agencies,” said Jean-Marc Nasr, head of space systems at Airbus, in a statement. “Together our teams are focused on creating an unmatched space destination both technologically and as a business operation.”

Though no specifics of the deal were released, Voyager will continue to retain 51% control. It appears that Voyager’s goal with this deal is to get its foot in the door of Europe. With ESA no longer considering doing any work on the space stations of either China or Russia, it needs a place to go after ISS is retired. By signing up Airbus as a partner Voyager makes Starlab the most likely go-to station for these European companies and governments.

Isn’t private enterprise and freedom wonderful? Without even trying Europe is going to get a space station of its own, and it will do it by hiring this private consortium of American and European companies.

NASA outlines its expected needs as a space station customer

NASA has now published an updated detailed specification of what it will want to do on the four private space stations being built to replace ISS.

NASA published two white papers Feb. 13 as part of a request for information (RFI) for its Commercial Low Earth Orbit Destinations effort to support development of commercial stations. The documents provide new details about how NASA expects to work with companies operating those stations and the agency’s needs to conduct research there.

One white paper lists NASA’s anticipated resource needs for those stations, including crew time, power and volume, broken out for each of the major agency programs anticipated to use commercial stations. Companies had been seeking more details about NASA requirements to assist in the planning of their stations.

,,,The second white paper outlines the concept of operations NASA envisions for its use of commercial space stations. The 40-page document described in detail what it expects from such stations in terms of capabilities, resources and operations, as well as what oversight the agency anticipates having.

At the moment NASA has contracts with four different space station companies or partnerships, Axiom, Blue Origin, Nanoracks and Northrop Grumman, each of which is building its own station. Because NASA will initially be the biggest customer for these stations its requirements will help shape those stations significantly, which is why this information is of critical importance for the private companies.

At the same time, NASA is not dictating specific designs. The agency remains the customer, buying time on private facilities that will be owned privately and be free to sell their product to others. Thus, the designs of these stations might not match exactly what NASA desires, since even now there are other customers interested in buying space station time and space.

Hilton chosen to design hotel suites on Nanoracks’ Starlab private space station

Nanoracks' Starlab space station
Nanoracks’ Starlab space station

Capitalism in space: Hilton has been chosen to design the hotel suites inside the Starlab private space station that Nanoracks is building and hopes to launch sometime this decade.

Voyager and Hilton will partner in the areas of architecture and design, leveraging Hilton’s word-class creative design and innovation experts, to develop Space Hospitality crew headquarters aboard Starlab, including communal areas, hospitality suites, and sleeping arrangements for the astronauts.

The announcement was made by Voyager Space, the Nanoracks’ division that is building Starlab, and already has a $160 million development contract from NASA.

Billionaire wants to build spinning space station for testing artificial gravity

Capitalism in space: Billionaire Jed McCaleb, who earned billions in software and cryptocurrency, has started a company dubbed Vast to develop and build a spinning space station for testing the pros and cons of artificial gravity.

McCaleb is self-financing at the moment, though he hopes to turn his station eventually into a money-making proposition. His company is also right now very small, but he clearly is going for the best in who he is hiring:

Currently, the company has about 20 employees, including Kyle Dedmon, former SpaceX vice president for construction and facilities; Tom Hayford, a systems engineer who has worked for Relativity Space and SpaceX; Molly McCormick, a former SpaceX human factors engineer and Honeybee Robotics program manager; and Colin Smith, a former SpaceX propulsion engineer. In addition, former SpaceX vice president Hans Koenigsmann is advising the company.

This new private space station joins by my count the four other American private space stations now proposed, including Axiom’s station, a partnership led by Sierra Space building Orbital Reef, Nanorack’s Starlab station, and Northrop Grumman’s upgrade station based on its Cygnus freighter.

That’s five private space stations under development in the United States. And there could be others that I have missed.

NASA outlines plans for ISS deorbit and the transition to commercial stations

Capitalism in space: NASA on January 31st released its updated plan for transitioning all government manned orbital operations to commercial private space stations in the next eight years in preparation for the deorbiting of ISS in early 2031.

You can read the report here [pdf]. The key paragraph however is this:

NASA has … signed agreements with three U.S. companies (Blue Origin of Kent, Washington; Nanoracks LLC of Houston, Texas; and Northrop Grumman Systems Corporation of Dulles, Virginia) to develop commercial destinations in space that go directly to orbit, i.e., free-flyers. The awards, along with the Axiom concept [where the private station starts as part of ISS and then later separates], are the first part of a two-phase approach to ensure a seamless transition of activity from the ISS to commercial destinations. During this first phase, private industry, in coordination with NASA, will formulate and design [commercial space stations] capabilities suitable for potential Government and private sector needs. The first phase is expected to continue through 2025.

For the second phase of NASA’s approach to a transition toward [commercial space stations], the Agency intends to certify for NASA crew member use [commercial space stations] from these and potential other entrants, and ultimately, purchase services from destination providers for crew to use when available.

It is NASA’s goal to be one of many customers of commercial LEO destination services, purchasing only the goods and services the Agency needs. [Commercial space stations], along with commercial crew and cargo transportation, will provide the backbone of the human LEO ecosystem after the ISS retires. [emphasis mine]

The report predicts that, by using private stations instead of building its own, the agency will save up to two billion dollars per year, money it can than use of planetary missions. This of course is assuming NASA cancels SLS. If not, I predict that overpriced cumbersome rocket will quickly absorb all this money saved.

The highlighted sentence indicates that NASA continues to accept entirely the recommendations I made in my 2017 policy paper, Capitalism in Space [a free pdf download]. In fact, that sentence is almost an exact quote from one of most important recommendations.

Bigelow sues NASA for $1 million

The commercial space station company Bigelow Aerospace has now sued NASA for $1 million, claiming that the agency has refused to pay it for work done.

Bigelow Aerospace said it entered into an agreement with NASA on the B330 project in August 2016 to perform and complete a certain long-term pressure leak test on its prototype. The purpose of the test was to demonstrate that the B330 meets NASA’s standards of construction and reliability.

According to the lawsuit, Bigelow Aerospace was required to perform a leak test on its module and “provide certain periodic test reports” to NASA. The reports were scheduled and were required to summarize the results of the test, specifically whether the B330 had met certain standards set by NASA. “Importantly, the Contract contains no requirement that Bigelow Aerospace had to provide NASA with continuous and/or raw” data, the lawsuit alleges.

Bigelow Aerospace said NASA breached its contract with the agency by refusing to pay the full amount to the company. The company said that its damages are in excess of $1 million because it had to hire attorneys to bring the lawsuit forward.

According to the suit, multiple attempts were made between January and February to demand payment. The lawsuit said that NASA’s attorney requested raw test data from Bigelow’s testing carried out under the contract as a prerequisite of being paid the amount owed. “However, this requirement was not a term of the Contract, and was an attempt by NASA to place additional requirements on Bigelow Aerospace that had not been part of the parties’ agreement,” according to the lawsuit.

Until 2016, when Bigelow’s prototype BEAM module was installed on ISS, this company seemed the world’s unmatched leader in the construction of private commercial space station modules. It had already flown two prototypes successfully, and then built BEAM for NASA in only two years for a mere $17 million.

Since then it seems Bigelow has been stalled by Washington politics and some insider maneuvering at NASA. In January 2020 NASA picked Axiom to build the first commercial operational private modules to be attached to ISS, not Bigelow. I wondered then why Bigelow had been bypassed by a company that had never built anything. Noting how Axiom had numerous NASA insiders in its management, many with links to Boeing, I concluded:

China announces international experiments to fly on its space station

The new colonial movement: China and the UN today jointly announced the nine international experiments that China will fly on its own space station, set to be completed by 2022.

The nine projects involve 23 entities from 17 countries in the fields of aerospace medicine, space life sciences and biotechnology, microgravity physics and combustion science, astronomy and other emerging technologies.

It seems to me that the competition in space is definitely heating up. Both China and Indian now plan their own space stations. And the Trump administration’s announcement that it will allow private commercial and competitive operations on ISS, is certainly going to lead eventually to more than one private station in orbit, plus ISS.

The result is going to be many different stations, all offering different capabilities and all in competition to lower the cost to get there and to do research or to sightsee. All are also going to be contributing aggressively in learning how to build vessels that humans can live on for long periods, which in turn will teach us how to build interplanetary spaceships. In fact, every one of these stations will be prototypes for those interplanetary spaceships.

Isn’t competition wonderful? After almost thirty years of boring international cooperation on ISS, with little new achievement or innovation, the space station competition coming in the next decade will revitalize space exploration in ways we as yet cannot imagine.

Bigelow establishes company to market its private space stations

Capitalism in space: Bigelow Aerospace yesterday established a marketing company to research and find potential customers for its private space stations.

“You’ll need deep pockets if you’re interested in staying aboard a Bigelow station; prices will likely run in the ‘low seven figures,'” Bigelow said today. He doesn’t expect tourist jaunts to make up the bulk of his business, however. “What we’ve always anticipated and expected is that we would be very involved in helping foreign countries to establish their human space programs, and be able to facilitate whatever their needs were in whatever context that they wanted to pursue,” he said. “The corporate world, obviously, is huge, and [leveraging] that is also our intent.”

Bigelow already says it will launch to of its large B330 modules in 2021, with another aimed for lunar orbit in 2022. I must note that the 2021 launch date appears to be year later then earlier announcements.

ULA to launch two Bigelow space station modules

The competition heats up: ULA and Bigelow Aerospace have announced a partnership to launch two of Bigelow’s largest space station modules, each with about as much interior space as both Skylab and Mir.

Both will be ready for launch by 2020. Neither company has made clear if they have any outside investment, though they left open the option of working with NASA and having the modules attached to ISS.

Bigelow announces prices for visiting or renting their space station modules.

The competition heats up: Bigelow Aerospace announces prices for visiting or renting their space station modules.

For countries, companies, or even visiting individuals that wish to utilize SpaceX’s Falcon 9 rocket and Dragon capsule, Bigelow Aerospace will be able to transport an astronaut to the Alpha Station for only $26.25 million. Using Boeing’s CST-100 capsule and the Atlas V rocket, astronauts can be launched to the Alpha Station for $36.75 million per seat. In stark contrast to the short stays of a week or so aboard the ISS that we have seen wealthy individuals pay as much as $40 million for, astronauts visiting the Bigelow station will enjoy 10 – 60 days in orbit. During this time, visiting astronauts will be granted access to the Alpha Station’s shared research facilities. Examples of available equipment include a centrifuge, glove-box, microscope, furnace, and freezer. Also, potential clients should note that as opposed to the ISS, where astronauts dedicate the lion’s share of their time to supporting station operations and maintenance, astronauts aboard the Alpha Station will be able to focus exclusively on their own experiments and activities, ensuring that both nations and companies can gain full value from their investment in a human spaceflight program. [emphasis in original]

The release also describes price plans whereby the customer can rent part of a module for a period of time, as well as the prices for the naming rights to a module.

I hadn’t heard about it elsewhere and do not remember if this is old news or not. The announcement on the website is undated. Nonetheless, as the release notes, these prices undercut the fees charged by the Russians and provide far more opportunities for the customer.

Bigelow Aerospace has expanded its workforce as well doubled its factory space in response to the commercial contracts NASA recently awarded.

The competition heats up: Bigelow Aerospace has expanded its workforce as well doubled its factory space in response to the commercial contracts NASA recently awarded.

The company just opened a 185,000-square-foot addition, bringing its North Las Vegas plant up to about 350,000 square feet. It slashed its work force from 150 before the recession to 50 during the downturn; now, it’s looking to jump back up to 90 workers by Christmas. It’s hiring structural, mechanical and electrical engineers, as well as chemists, molecular biologists and workers who craft composite spacecraft parts.
