New Delhi:

The anti-satellite weapon capability demonstrated by India was first developed by the US in 1959, primarily to counter the erstwhile Soviet Union.

What is an ASAT?

ASATs (Anti-Satellite Weapons) are aimed at destroying or disabling space assets, whether military or civilian, offensive or defensive, according to a document of the United Nations Institute for Disarmament Research (UNIDIR).

They are generally of two types: kinetic and non-kinetic.

Kinetic ASATs:

They must physically strike an object in order to destroy it. Examples of kinetic ASATs include ballistic missiles, drones that drag an object out of orbit or detonate explosives in proximity to the object, or any item launched to coincide with the passage of a target satellite.

This means any space asset, even a communications satellite, could become an ASAT if it is used to physically destroy another space object.

Non-kinetic ASATs:

A variety of nonphysical means can be used to disable or destroy a space object.

These include frequency jamming, blinding lasers or cyber attacks. These methods can also render an object useless without causing the target to break up and fragment absent additional forces intervening.

Guidelines suggested for ASAT tests:

In 2018, the UNIDIR proposed three ASAT test guidelines. Under the 'No Debris' guideline, if an actor wishes to test ASAT capabilities, they should not create debris.

If an actor must create debris during an ASAT test, it should be carried out at an altitude sufficiently low that the debris will not be long-lived.

It also suggested that actors testing ASATs should notify others of their activities (even if they are not completely transparent on the motivation behind the test) to avoid misperceptions or misinterpretations.

However, there is no consensus among the space-faring nations on the guidelines.

"We are working on different measures, but nothing has been formally adopted," Daniel Porras, Space Security Fellow at UNIDIR, said.
