Russia’s space weapon: Is it nuclear and does it pose a threat?

According to a series of reports, the US government has privately warned lawmakers and European allies that Russia is planning to launch a nuclear-capable space weapon.

The news comes after U.S. House Intelligence Committee Chairman Mike Turner announced: vague warning It cited a “grave national security threat” and asked US President Joe Biden to “declassify all information related to this threat” for more public discussion. Since then, news reports have revealed additional details about what Russia’s mystery weapon is. Here’s what we know so far:

Does this mean Russia aims to deploy nuclear missiles and bombs into space?

This remains unknown.report from ABC News and new york times The term “nuclear weapon” may mean a weapon capable of producing an explosion involving a fission or fusion reaction.If this is true, it would be a violation of the rules 1967 Outer Space TreatyIt prohibits signatories, including Russia and the United States, from placing nuclear weapons or other weapons of mass destruction in space.

Although a nuclear explosion in space would not directly harm people on Earth, it could destroy and disable multiple satellites.When the United States detonated a nuclear bomb in low Earth orbit during that period starfish prime In a 1962 experiment, the resulting radiation damaged or destroyed about a third of the satellites in low Earth orbit at the time.

However, there is another possibility that does not involve nuclear weapons.

What else does Russia have in its nuclear capabilities in space?

Russian space weapons may simply use nuclear power to power onboard systems. PBS News Hour U.S. officials said the Russian weapon was “probably nuclear-powered.”

Russia and the United States have used various forms of nuclear power in space for decades. One form includes nuclear fission reactors, such as those found in civilian nuclear power plants, which derive their power from an ongoing nuclear chain reaction.

The United States launched an experimental nuclear reactor into space in 1965, while Russia reportedly launched at least 34 nuclear reactors aboard satellites between 1967 and 1988. World Nuclear Association.

The United States, Russia, and other countries have also launched space missions using radioisotope systems. These use heat from the natural decay of radioactive materials as a power source, but they provide much less power than nuclear fission reactors.

What does this Russian space weapon actually do?

News reports agree that Russian weapons are designed to target satellites in space, rather than directly harming anyone or anything on the ground. However, if this weapon is able to knock satellites out of orbit, these objects could fall to the planet’s surface and cause severe damage. If they blow away, the resulting cloud of space junk could threaten other satellites and even the International Space Station. This could even trigger a Kessler syndrome scenario, where a chain reaction of space debris gets out of control and makes it virtually impossible for satellites to survive in Earth orbit.

Various countries, including Russia, the United States, China and India, have previously tested anti-satellite weapons (ASATs), which shoot missiles from Earth and shoot down objects in orbit. But countries have been much quieter about whether they have actually deployed ASAT weapons into space.

What does Russia say about the potential of this weapon?

A spokesperson for Russian President Vladimir Putin’s government reportedly called the U.S. warning a “malicious hoax” aimed at pushing the U.S. Congress to pass legislation authorizing more military aid to Ukraine. Ta. Reuters. Since Russia launched a full-scale invasion of Ukraine in February 2022, the United States and Europe have supported Ukraine’s military resistance against Russian forces.

Why does Russia need new anti-satellite weapons?

Satellites are important for both military and civilian applications that have a huge impact on modern life. They monitor the weather, power GPS systems, provide space-based surveillance, and enable communications. For example, SpaceX’s Starlink satellite constellation has proven essential to the Ukrainian military in coordinating drone and artillery fire against Russian forces on the battlefield.

A U.S. official quoted by PBS NewsHour suggested that Russian space weapons have “electronic warfare capabilities to target U.S. satellites critical to U.S. military and civilian communications.”

According to some sources, Russia has spent years developing a space-based electronic warfare system that can jam communications signals to and from satellites. report This is by the Secure World Foundation, a space security organization based in Colorado.Victoria Samson at the Secure World Foundation Said Such a Russian space weapon could be powered by nuclear power.

So how dangerous is this new anti-satellite weapon?

The good news is that if this space weapon sabotages satellites rather than physically destroying them, it will not cause a catastrophic space debris scenario like Kessler syndrome. However, it can still be dangerous.

Space weapons that use electronic warfare to jam signals could effectively disable satellites. That could disrupt critical battlefield communications, render GPS guidance systems inoperable and obscure reconnaissance satellites, making it more difficult for the United States to coordinate military forces around the world.
