Space Race in the 21st Century

Space Race in the 21st Century

America won the first space race.
Now we’re in a new one, with a new adversary—and this time, victory is not assured.

This is a story of the rise and status of China as a modern space power, and what it means for American leadership in the domain.

A New Rival Emerges

China’s space program emerged from rocket and ballistic missile research during the Cold War. Since the start of the 21st century, progress has accelerated dramatically, with China compressing decades’ worth of milestones into roughly twenty years.

The Launch Gap Is Narrowing

Space launch is the most fundamental constraint on space power. The U.S. leads in two critical areas—super heavy-lift and high-cadence reusable launch—but nothing suggests China won’t achieve both this decade.

Cost Per Kilogram to LEO

Falcon 9 — partially reusable$857/kg
Long March 2D — expendable$8,571/kg

This order-of-magnitude cost gap explains why Starlink exists and China’s Guowang doesn’t—yet. Cheap, reusable launch isn’t just a technical advantage; it’s the economic foundation of modern space infrastructure.

⚠ The U.S. operates two super heavy-lift rockets (SLS and Falcon Heavy). China has zero—but the Long March 10 is set to conduct its first test flight in 2026. China also has a number of partially and fully reusable rockets under development.

Orbit Gets Contested

China has rapidly increased their number of rendezvous and proximity operations in recent years—against both their own and American satellites

0
proximity operations in 2023
Chinese satellites against American satellites—up from near zero a decade earlier. The U.S. Space Force describes this as China “practicing dogfighting in space.”

Key Demonstrations

Shijian-21 (2021)

Rendezvoused with defunct BeiDou-2 in GEO, towed it 300 km to a graveyard orbit, and returned to its original position.

RendezvousTowingDebris Mitigation

Shijian-25 (2025)

In-space refueling and mission extension. Later conducted coordinated proximity operations with SJ-21.

⚠ The same capability that tows debris can tow an adversary’s satellite out of position. These are inherently dual-use technologies being normalized through repeated demonstration.
Part IV

The Race for Information Dominance

AI gives satellites autonomy. Quantum gives them unbreakable links. Together, they determine who controls the information edge in orbit—faster decisions, resilient comms, superior awareness.

0
satellites in china’s “three-body” ai constellation
Each carries AI processors capable of 744 trillion operations per second. Combined: 1 quintillion ops/sec—an AI supercomputer in orbit, cooled by the vacuum of space.

China’s Jilin-1 satellites have demonstrated AI-based tracking of stealth aircraft from orbit. Beijing-3 autonomously plans its own imaging schedule without ground control.

⚠ If China fields a quantum-secure satellite network first, it establishes an eavesdrop-proof channel for military and diplomatic traffic—while potentially blinding others to its communications.

A Look Towards the Future:
The Moon Is the Prize

Both nations plan crewed landings this decade and permanent bases in the 2030s. The competition is about who defines the technical standards, operational norms, and economic architecture of the lunar frontier.

cost of a single SLS launch
Total SLS program costs estimated at $23.8 billion as of 2022. And SLS is just one element of the Artemis program (the launch vehicle). Artemis suffers from other problems, and relies on an architecture that requires orbital refueling of Starship HLS—a capability never demonstrated.

There is a real possibility that China lands people on the Moon before the United States returns there.

Why the Moon Matters Beyond Symbolism

Staging Base

1/6th Earth’s gravity—far cheaper to launch deeper missions from the lunar surface.

Fuel Depot

Lunar water ice converts to rocket fuel. Control ISRU, control the deep-space supply chain.

Standard-Setter

First to build permanent infrastructure defines the norms everyone else follows.

⚠ Ultimately, if China builds out permanent presence on the Moon before and faster than the U.S. does, American firms could find themselves operating within an environment shaped by Chinese technical standards, operational norms, and access arrangements

Space leadership is not a permanent inheritance.
It must be continuously earned.

China’s approach benefits from long planning horizons, centralized coordination, and unified strategic goals. The central risk is not sudden displacement—but the gradual erosion of relative advantage if leadership is not deliberately sustained.
