Space is the new frontier in the 21st century

The New Frontline: Cyber and Space Warfare

As Russia held its annual Victory Day parade this year, a dramatic display of military might was not only seen on the streets of Moscow but also in the skies above Ukraine. Hackers aligned with the Kremlin managed to seize control of an orbiting satellite that provides television services to Ukraine. Instead of regular programming, Ukrainian viewers were met with footage of the Russian parade—showcasing waves of tanks, soldiers, and military equipment. This act was more than just a symbolic gesture; it was a clear demonstration that 21st-century warfare extends beyond traditional battlefields into the realms of cyberspace and outer space.

Disabling a satellite can have catastrophic consequences without a single bullet being fired. By targeting a satellite’s security software or disrupting its communication signals from Earth, adversaries can cause significant disruptions. Tom Pace, CEO of NetRise, a cybersecurity firm focused on supply chain protection, explained the gravity of such actions. “If you can impede a satellite's ability to communicate, you can cause a significant disruption,” he said. He emphasized the importance of systems like GPS, noting that losing access to such technology could lead to widespread confusion and chaos.

Satellites as Strategic Assets

With over 12,000 operational satellites currently orbiting the Earth, these devices play a critical role in modern life. They are essential for broadcast communications, military operations, navigation systems like GPS, intelligence gathering, and even economic supply chains. Additionally, they are vital for early missile detection, providing warnings of potential threats.

This makes satellites a prime target for adversaries seeking to undermine an opponent’s economy, military readiness, or psychological stability. For instance, when Russian forces invaded Ukraine in 2022, hackers targeted Viasat, a U.S.-based satellite company used by Ukraine’s government and military. The attack, which Kyiv blamed on Moscow, involved malware that infected tens of thousands of modems, causing outages across Europe.

National security officials warn that Russia is developing a nuclear, space-based weapon capable of destroying nearly all satellites in low-Earth orbit at once. This weapon would combine a physical attack that spreads outward, destroying additional satellites, while the nuclear component would fry their electronics. U.S. officials declassified information about the weapon after Rep. Mike Turner, R-Ohio, raised concerns about the technology. Turner has urged the Department of Defense to provide classified briefings to lawmakers on the weapon, which would violate international treaties prohibiting weapons of mass destruction in space.

Turner likened the weapon to Sputnik, the first artificial satellite launched by the Soviet Union in 1957. “If this anti-satellite nuclear weapon would be put in space, it would be the end of the space age,” he said. “It should never be permitted to go into outer space. This is the Cuban Missile Crisis in space.”

The Lunar Race and Beyond

Beyond the threat of space-based weapons, the moon and asteroids hold valuable resources that could spark future conflicts. Valuable minerals and materials found on the moon and in asteroids could become a new frontier for competition as nations seek to exploit new technologies and energy sources.

Acting NASA Administrator Sean Duffy recently announced plans to send a small nuclear reactor to the moon, emphasizing the need for the U.S. to do so before China or Russia. “We're in a race to the moon, in a race with China to the moon,” Duffy said. “To have a base on the moon, we need energy and some of the key locations on the moon. ... We want to get there first and claim that for America.”

The moon is rich in helium-3, a material scientists believe could be used in nuclear fusion to generate vast amounts of energy. While this technology is still decades away, control over the moon in the coming years could determine which countries emerge as global superpowers. Joseph Rooke, a London-based cybersecurity expert, noted that dominance over Earth’s energy needs could mean “game over” for those who fail to secure it.

China and Russia have also announced plans for their own nuclear plants on the moon in the coming years, while the U.S. continues to plan missions to both the moon and Mars. Artificial intelligence is likely to accelerate this competition, as well as the demand for the energy required to power AI systems.

Space Security and the U.S. Response

Despite its steps into space, China opposes any extraterrestrial arms race. According to Liu Pengyu, a spokesperson for China's Embassy in Washington, it is the U.S. that is threatening to militarize space. “It has kept expanding military strength in space, created space military alliances, and attempted to turn space into a war zone,” Liu said. “China urges the U.S. to stop spreading irresponsible rhetoric, stop expanding military build-up in space, and make due contribution to upholding the lasting peace and security in space.”

In response to growing threats, the U.S. Space Force was established in 2019 to protect American interests in space and defend U.S. satellites from attacks. Although smaller than the Army, Navy, or Air Force, the Space Force is growing rapidly. It operates an unmanned space shuttle, the X-37B, used for classified military missions and research. The craft recently returned to Earth after more than a year in orbit.

The U.S. military views access to space as a vital national security interest. “Space is a warfighting domain, and it is the Space Force's job to contest and control its environment to achieve national security objectives,” the Space Force stated.

American dominance in space has largely gone unchallenged since the end of the Cold War, but the rising threats from Russia and China highlight the need for a more aggressive approach. As Rep. Turner noted, the hope is that the U.S. can take steps to ensure that Russia and China do not gain the upper hand, and that the frightening potential of space weapons is never realized. “You have to pay attention to these things so they don't happen,” he said.
