Is the US in a space race against China?

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 roughly US$59.8 billion^[8]. 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 billion^[9] in 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 are 5,465 total operational satellites^[10] in orbit around Earth. The U.S. operates 3,433, or 63% of those. In contrast, China has 541.

Similarly, the U.S. has more active spaceports^[11] than China. With seven operational launch sites at home and abroad^[12] and at least 13 additional^[13] spaceports in development^[14], the U.S. has more options to launch payloads into various orbits. In contrast, China has only four operational spaceports^[15] with two more planned^[16], 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 attempted 55 orbital launches^[17], 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 with 14 other nations^[18], including Russia, to operate the International Space Station^[19]. The ISS is quite large, with 16 modules, and has driven technological and scientific breakthroughs^[20]. But the ISS is now 24 years old, and participating nations are planning to retire it in 2030^[21].

The Chinese Tiangong space station^[24] is the new kid on the block. Construction was only completed in late 2022^[25], 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, despite having invited others to join^[26].

China is undoubtedly expanding its space capabilities, and in a report published in August 2022, the Pentagon predicted that China would surpass U.S. capabilities^[27] in 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 cultivating international^[28] and commercial^[29] partnerships in everything from developing specific space technologies to flying humans into space. The U.S. government has also signed 169 space data sharing agreements^[30] with 33 states and intergovernmental organizations, 129 with commercial partners and seven with academic institutions.

China also has allies that help with space – most notably Russia^[31] and members of the Asia-Pacific Space Cooperation Organization^[32], including Iran, Pakistan, Thailand and Turkey. China’s collaborators are, however, fewer in number and have far less developed space capabilities.

In just two years, 24 nations, including Brazil, have joined the U.S.-led Artemis Accords. This international agreement outlines the goals of space exploration in the near future. Ministério da Ciência, Tecnologia e Inovações/Wikimedia Commons, CC BY^[33][34]

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 often cited as evidence of the space race^[35], but they are very different in terms of partnerships and scope.

In 2019, Russia and China agreed^[36] to 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^[37],” 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.-led Artemis Accords^[38]. This international agreement outlines shared principles of cooperation^[39] for 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 staggering number of private companies^[40] to develop a range of technologies^[41], from lunar landers^[42] to lunar construction methods^[43] and more^[44].

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.

India^[45] spends billions on space and plans to return to the Moon^[46], possibly with Japan^[47], in the near future. South Korea, Israel, Japan, the United Arab Emirates^[48], Turkey^[49], Germany^[50] and the European Union^[51] are also planning independent lunar missions. Japan has developed impressive technological space capabilities, including rendezvous proximity technology to send a spacecraft to an asteroid and bring samples back to Earth^[52], that rival and even surpass those of China^[53].

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.
