Is Russia testing a new anti-satellite weapon?

Subject: Science and tech

Section: defence

Context:

• On February 15, U.S. National Security Council spokesperson John Kirby confirmed the claims referred to a space-based “anti-satellite weapon” of Russian provenance.
• Mr. Kirby also said Russia hadn’t yet deployed the ‘capability’— meaning the object wasn’t yet in orbit and that it would violate the Outer Space Treaty (OST), a multilateral agreement that prohibits the placement of weapons of mass destruction in earth’s orbit.

Anti-Satellite Weapons (ASAT)

• Anti-satellite (ASAT) technology refers to the capability to intercept, disable, or destroy satellites in orbit. This technology is primarily developed for defence and strategic purposes.

Types of Anti-Satellite Weapons

• ASATs are broadly classified into two types: Those that employ brute force and those that do not.
• Kinetic energy methods: This involves launching a missile that intercepts and physically collides with the target satellite to destroy it.
  • The kinetic energy ASATs physically collide with satellites and can reach altitudes. These ASATs can be ballistic missiles, drones, and other satellites.
• Non-kinetic methods: They use non-physical attacks such as cyber-attacks, jamming, and even lasers to blind satellites without physically destroying them.
  • All of these attacks can be launched from the air, low orbit, or even ground installations.

Countries with ASAT Technology

• ASATs were first developed during the Cold War era.
• They have never been used in warfare, but have been used to remove decommissioned satellites.
• Besides India, three other countries have successfully demonstrated anti-satellite (ASAT) technology in tests; the United States, Russia and China.

Need for ASAT Technology

• National security: ASAT weapons can be developed with the goal of protecting national security interests such as safeguarding critical infrastructure, military communications, and intelligence-gathering capabilities that rely on satellites.
• Destroying retired satellites: There are many satellites in space right now, many of which have outlived their usefulness and are orbiting aimlessly.
• Deterrence: The possession of ASAT capabilities can act as a deterrent to potential adversaries. Knowing that a nation can defend its space assets and retaliate if its satellites are targeted may discourage hostile actions in space.
• Technological advancements: Advances in missile and space technology make it feasible for more nations to develop ASAT capabilities.

Implications of Anti-Satellite Weapons

• Space debris: Destructive ASAT tests result in the creation of a substantial amount of space debris, posing a severe threat to other satellites and spacecraft in space, increasing the risk of collisions.
• Kessler Syndrome: It can lead to Kessler Syndrome, a situation where an increasing amount of space debris in orbit leads to a self-sustaining cascade of collisions, creating more debris and making space activities increasingly hazardous.
• Race for arms control: The proliferation of ASAT capabilities may lead to an arms race in space, resulting in the weaponisation of space.
• International concern: The consequences of ASAT testing, especially in light of the dangers of debris, have prompted calls for a global ban on destructive ASAT tests.
