Headlines proclaiming the rise of a new “space race”between the U.S. and Chinahave become common in news coverage following many of the exciting launches in recent years. Experts have pointed to China’srapid advancementsin space as evidence of an emerging landscape where China isdirectly competingwith the U.S. for supremacy.
This idea of a space race between China and the U.S. sounds convincing given the broader narrative of China’s rise, but how accurate is it? As a professor whostudies space and international relations, my research aims to quantify the power and capabilities of different nations in space. When I look at various capacities, the data paints a much more complex picture than a tight space race between the U.S. and China. At least for now, the reality looks more like what I call a complex hegemony – one state, the U.S., is stilldominating in key space capabilities, and this lead is further amplified by astrong network of partners.
A clear leader makes for a boring race
Calling the current situation a race implies that the U.S. and China have roughly equal capabilities in space. But in several key areas, the U.S. is far ahead not only of China, but of all other spacefaring nations combined.
Starting with spending: In 2021, the U.S. space budget was roughlyUS$59.8 billion. China has been investing heavily in space and rocket technology over the last decade and has doubled its spending in the last five years. But with an estimated budget of$16.18 billionin 2021, it is still spending less than a third of the U.S. budget.
The U.S. also leads significantly in the number of active satellites. Currently, there are5,465 total operational satellitesin orbit around Earth. The U.S. operates 3,433, or 63% of those. In contrast, China has 541.
Similarly, the U.S. has moreactive spaceportsthan China. Withseven operational launch sites at home and abroadand at least13 additionalspaceportsin development, the U.S. has more options to launch payloads into various orbits. In contrast, China has onlyfour operational spaceportswithtwo more planned, all located within its own territory.
Parity with nuance
While the U.S. may have a clear advantage over China in many areas of space, in some measures, the differences between the two countries are more nuanced.
In 2021, for instance, China attempted55 orbital launches, four more than the U.S.‘s 51. The total numbers may be similar, but the rockets carried very different payloads to orbit. The vast majority – 84% – of Chinese launches had government or military payloads intended mostly for electronic intelligence and optical imaging. Meanwhile, in the U.S., 61% of launches were for nonmilitary, academic or commercial use, predominantly for Earth observation or telecommunications.
Space stations are another area where there are important differences hiding beneath the surface. Since the 1990s, the U.S. has worked with14 other nations, including Russia, to operate theInternational Space Station. The ISS is quite large, with 16 modules, and has driventechnological and scientific breakthroughs. But the ISS is now 24 years old, and participating nations are planning toretire it in 2030.
The ChineseTiangong space stationis the new kid on the block. Construction was onlycompleted in late 2022, and it is much smaller – with only three modules. China has built and launched all of the different parts and remains the sole operator of the station, despitehaving invited others to join.
China is undoubtedly expanding its space capabilities, and in a report published in August 2022, the Pentagonpredicted that China would surpass U.S. capabilitiesin space as early as 2045. However, it is unlikely that the U.S. will remain stagnant, as it continues to increase funding for space.
Allies as force multipliers
A major point of difference between the U.S. and China is the nature and number of international collaborations.
For decades, NASA has been fruitfully cultivatinginternationalandcommercialpartnerships in everything from developing specific space technologies to flying humans into space. The U.S. government has alsosigned 169 space data sharing agreementswith 33 states and intergovernmental organizations, 129 with commercial partners and seven with academic institutions.
China also has allies that help with space – most notablyRussiaand members of theAsia-Pacific Space Cooperation Organization, including Iran, Pakistan, Thailand and Turkey. China’s collaborators are, however, fewer in number and have far less developed space capabilities.
Efforts to return to the surface of the Moon excellently highlight this difference in ally support and synergy. Both the U.S. and China have plans to send people to the surface of the Moon and to establish lunar bases in the near future. These competing lunar aims are oftencited as evidence of the space race, but they are very different in terms of partnerships and scope.
In 2019,Russia and China agreedto jointly go to the Moon by 2028. Russia is contributing its Luna landers and Oryol crewed orbiters, while China is improving its Chang’e robotic spacecraft. Their future International Lunar Research Station is “open to all interested parties and international partners,” but, to date, no additional countries have committed to the Chinese and Russian effort.
In contrast, since 2020, 24 nations have joined the U.S.-ledArtemis Accords. This international agreement outlines sharedprinciples of cooperationfor future space activity and, through the Artemis Program, specifically aims to return people to the Moon by 2025 and establish a Moon base and lunar space station soon after.
In addition to the broad international participation, the Artemis Program has contracted with a staggeringnumber of private companiesto develop arange of technologies, fromlunar landerstolunar construction methodsandmore.
China is not the only game in town
While China may seem like the main competitor of the U.S. in space, other countries have space capabilities and aspirations that rival those of China.
Indiaspends billions on space and plans toreturn to the Moon, possiblywith Japan, in the near future.South Korea, Israel, Japan, the United Arab Emirates,Turkey,Germanyandthe European Unionare also planning independent lunar missions. Japan has developed impressive technological space capabilities, including rendezvous proximity technology to send aspacecraft to an asteroid and bring samples back to Earth, that rival and even surpassthose of China.
In the past, the space race was about who could reach the stars first and return home. Today, the goal has shifted to surviving and even thriving in the harsh environment of space. I believe it is not surprising that, despite its decisive lead, the U.S. has partnered with others to go to the Moon and beyond. China is doing the same, but on a smaller scale. The picture that emerges is not of a “race” but of complex system with the U.S. as a leader working closely with extensive networks of partners.
