Testing Ways to Produce Spare Parts in Space

Space exploration has always been about pushing boundaries and venturing into the unknown. Today, one of the most significant challenges is ensuring the sustainability and self-sufficiency of missions beyond Earth. Unlike terrestrial aircraft, spacecraft cannot simply land for repairs or maintenance. This has led to the development of innovative technologies like 3D printing, or additive manufacturing, to produce spare parts and tools in space. This capability not only reduces reliance on Earth-based supply chains but also opens the door to a burgeoning space-borne manufacturing industry.

Recent advancements in 3D printing technology have been tested in microgravity environments, with missions like Virgin Galactic’s Galactic 07 and experiments conducted aboard the International Space Station (ISS). These tests aim to refine the technology and understand its potential for long-term space missions, lunar bases, and even Martian habitats. By producing spare parts in space, astronauts can address unforeseen issues without waiting for resupply missions from Earth, significantly enhancing mission flexibility and safety.

The Role of 3D Printing in Space

3D printing in space is not just about creating spare parts; it’s about revolutionizing how we approach space exploration. Taylor Waddell, a pathways engineer at NASA and project leader of the SpaceCal initiative, highlights the versatility of 3D printing. From dental crowns to nuts and bolts, the technology can produce a wide range of items using materials like silicones, hard acrylics, biogels, and even metals. This adaptability makes 3D printing an invaluable tool for reducing mission risks and ensuring the success of long-duration missions.

One of the key challenges in space manufacturing is the behavior of materials in microgravity. For instance, liquid propellants in spacecraft tanks can slosh unpredictably, affecting the vehicle’s stability. Purdue University’s experiments aboard the Galactic 07 mission studied this phenomenon to improve spacecraft design. By understanding how liquids behave in zero gravity, engineers can develop safer and more efficient systems for future missions.

Additionally, the European Space Agency (ESA) and Airbus have been testing metal 3D printing on the ISS. Rob Postema, part of the ESA’s Low Earth Orbit Exploration Group, explains that continuous microgravity on the ISS allows for more comprehensive testing compared to suborbital flights. The ability to print metal parts in space could be a game-changer for maintaining the ISS, lunar bases, and future Mars habitats.

“3D printing in space will become commonplace because there are more private space stations being planned, including lunar and Martian habitats. It enables the production of things that people can’t predict before a mission.” – Taylor Waddell, NASA Pathways Engineer



Challenges and Future Opportunities

Despite its potential, in-space manufacturing faces several challenges. One of the primary concerns is the accuracy and quality of 3D-printed parts in microgravity. Anthony Moody, a former researcher on the SpaceCal project, emphasizes the importance of testing in controlled environments to improve the printer’s design. For example, adding vibration isolation to the printer can enhance its performance in space.

Another challenge is the noise generated by 3D printers, which limits their operation on the ISS to four hours a day. Rob Postema suggests that artificial intelligence and machine learning could automate the printing process, reducing the need for crew intervention and allowing for remote operations from Earth. This would not only improve efficiency but also free up astronauts to focus on other critical tasks.

Looking ahead, the growth of private space stations and extraterrestrial habitats will likely drive the demand for in-space manufacturing. As Taylor Waddell notes, 3D printing is a “useful tool for space exploration,” and its applications will continue to expand as the technology matures. From creating tools on-demand to building structures on the Moon or Mars, the possibilities are endless.

Conclusion

The ability to produce spare parts in space represents a significant leap forward in space exploration. By leveraging 3D printing technology, astronauts can address unforeseen challenges, reduce mission risks, and extend the lifespan of spacecraft and habitats. The experiments conducted aboard the Galactic 07 mission and the ISS have provided valuable insights into the behavior of materials in microgravity, paving the way for more advanced manufacturing techniques.

As we look to the future, in-space manufacturing will play a crucial role in enabling long-duration missions and establishing permanent extraterrestrial bases. With ongoing advancements in automation, materials science, and artificial intelligence, the potential for this technology is limitless. The journey to make space exploration more sustainable and self-sufficient has only just begun.

Google and SpaceX Plan AI Data Centers in Earth Orbit by 2027

Google and SpaceX are developing orbital AI data centers to overcome terrestrial energy limits, with prototype satellites launching in early 2027.

Published

on

This article summarizes reporting by The Wall Street Journal and Reuters. The original report is paywalled; this article summarizes publicly available elements and public remarks.

Alphabet’s Google is reportedly negotiating a rocket launch agreement with SpaceX to place artificial intelligence data centers into Earth’s orbit. According to reporting by The Wall Street Journal on May 12, 2026, the tech giant is looking to space to solve the massive energy and infrastructure bottlenecks currently plaguing terrestrial AI development.

The explosive growth of artificial intelligence has triggered an unprecedented demand for electricity, land, and cooling water. By moving compute infrastructure into orbit, companies hope to harness uninterrupted solar energy and the natural cooling properties of space to sustain the next generation of AI models.

This potential partnership builds on an existing financial relationship between the two companies. According to the reported details, Google acquired a 6.1 percent stake in SpaceX in 2015, and Google executive Don Harrison currently serves on the aerospace company’s board of directors.

The AI Energy Crisis and the Orbital Solution

Terrestrial Constraints

The primary catalyst for this ambitious concept is the staggering energy consumption of modern artificial intelligence. Industry estimates cited in the reporting indicate that global data centers consumed approximately 415 terawatt-hours (TWh) of electricity in 2024, representing roughly 1.5 percent of worldwide usage.

With AI-focused servers growing at an annual rate of 30 percent, projections suggest data center consumption could exceed 1,000 TWh by 2026, an amount equivalent to the entire national electricity usage of Japan. On Earth, this translates to grid overloads, rising energy costs, and significant pushback from local communities over land and water use.

The Space Advantage

In contrast, the orbital environment offers distinct advantages. Satellites can capture constant solar energy without the interruptions of weather or day-night cycles. SpaceX CEO Elon Musk has previously noted that space-based solar panels can generate roughly five times more power than their terrestrial counterparts. Additionally, the near-absolute zero temperatures of space could theoretically assist with thermal management, though dissipating heat in a vacuum remains a complex engineering hurdle.

Google’s Project Suncatcher and SpaceX’s Ambitions

Google’s Hardware in Orbit

Google has been quietly advancing its space-based computing strategy under an internal program dubbed “Project Suncatcher,” which was officially unveiled in November 2025. The initiative aims to deploy an interconnected network of solar-powered satellites equipped with Google’s proprietary Tensor Processing Unit (TPU) chips.

To test this technology, Google has partnered with satellite manufacturer Planet Labs. The companies plan to launch two prototype satellites by early 2027 to evaluate thermal management and system reliability, with an ultimate goal of scaling to an 81-satellite cluster.

“We’ll send tiny racks of machines and have them in satellites… and then start scaling from there.”

Google CEO Sundar Pichai, speaking in a November 2025 interview regarding the company’s orbital computing plans.

SpaceX’s Infrastructure Play

SpaceX is aggressively positioning itself as the foundational provider for this new orbital economy. In February 2026, the company filed for regulatory permission with the FCC to launch up to one million satellites dedicated to orbital data centers, operating at altitudes between 500 and 2,000 kilometers. SpaceX projects this massive constellation could eventually support 100 gigawatts of AI compute capacity.

The aerospace firm is also expanding its terrestrial AI ties. Recently, SpaceX signed an agreement to supply computing power to AI startup Anthropic using 220,000 Nvidia GPUs at its Memphis facility, with Anthropic expressing interest in utilizing future orbital data centers.

Market Competition and Technical Hurdles

Emerging Competitors

Google and SpaceX are not alone in their pursuit of space-based computing. The sector is attracting significant venture capital. Cowboy Space Corporation, led by Robinhood co-founder Baiju Bhatt, recently raised $275 million to construct orbital data centers and plans to build its own launch vehicles to avoid reliance on third-party rockets.

Similarly, startup Star Catcher secured $65 million in funding to develop a space-based power grid designed specifically to support these orbital computing facilities.

Engineering Challenges

Despite the influx of capital, formidable technical and economic barriers remain. Hardware must be heavily radiation-hardened to survive in orbit, which complicates the use of standard, off-the-shelf AI chips. Furthermore, transmitting massive datasets between Earth and orbit necessitates ultra-high-speed, laser-based communication networks.

Launch economics also pose a significant challenge. While SpaceX has drastically reduced the cost of reaching orbit, launching heavy data center racks remains substantially more expensive than constructing facilities on the ground. Additionally, deploying thousands of massive satellites will exacerbate existing concerns regarding space traffic management and orbital debris.

AirPro News analysis

If successful, the deployment of orbital data centers would represent a fundamental paradigm shift in global digital infrastructure. It frames low Earth orbit not merely as a domain for telecommunications or scientific exploration, but as the future backbone of the AI economy.

For the financial sector, the timing of these leaks is particularly notable. SpaceX is reportedly preparing for a highly anticipated Initial Public Offering (IPO) as soon as the summer of 2026, targeting a valuation of approximately $1.75 trillion following its recent merger with xAI (which valued the combined entity at $1.25 trillion). Highlighting its capacity to serve as the primary infrastructure provider for the AI boom effectively positions SpaceX as a critical AI investment, rather than strictly an aerospace company. Furthermore, a finalized deal between Google and SpaceX would mark a fascinating dynamic, given Elon Musk’s historical rivalries with Google’s leadership over AI development.

Frequently Asked Questions

What is Project Suncatcher?

Project Suncatcher is Google’s internal initiative to create an interconnected network of solar-powered satellites equipped with AI chips, effectively forming an orbital data center cloud.

Why put data centers in space?

Space offers uninterrupted solar energy and natural cooling properties, which could help alleviate the massive electricity, land, and water demands currently straining terrestrial AI data centers.

When will the first orbital data centers launch?

According to current timelines, Google and Planet Labs plan to launch two prototype satellites by early 2027 to test thermal management and reliability in orbit.
