In a week where national security has , the White House confirmed on Thursday that it had evidence that Russia was developing a .

John Kirby, the National Security Council spokesperson, that the White House believe Russia鈥檚 programme to be 鈥渢roubling鈥, despite 鈥渘o immediate threat to anyone鈥檚 safety鈥.

The problem is that, depending on what type of weapon this is, the consequences of using it could be indiscriminate 鈥 threatening everyone鈥檚 satellites and causing a breakdown of the vital services that come from space infrastructure.

The White House revelations come after House Intelligence Committee Chairman Mike Turner urged the administration, late on Wednesday, to declassify information concerning what he called a 鈥渟erious national security threat鈥. There were then several days and speculation about Russia , or deploying an anti-satellite .

Kirby did not fully outline the nature of the threat, that officials believed the weapons system was not an 鈥渁ctive capability鈥 and had not been deployed. To reassure those listening, Kirby said that the weapon was not one that could be used to cause physical destruction on Earth but that the White House was monitoring Russian activity and would 鈥渃ontinue to take it very seriously鈥.

During a visit to Albania on Thursday, Secretary of State Antony Blinken confirmed the news and stated that he expected to have more to say soon, adding that the Biden administration was 鈥渁lso conferring with allies and partners on the issue鈥.

While discussing the matter with Indian Foreign Minister Jaishankar and Chinese Foreign Minister Wang Yi at the , Blinken is to have 鈥渆mphasised that the pursuit of this capability should be a matter of concern鈥.

<91日韩AV>Denials from Russia

Moscow immediately denied the existence of such a programme and that it was a 鈥渕alicious fabrication鈥 created by the Biden administration to pressurise Congress into passing the USD$97bn (拢77bn) , $60bn of which was destined for Ukraine. Kremlin spokesman Dmitry Peskov : 鈥淚t is obvious that the White House is trying, by hook or by crook, to encourage Congress to vote on a bill to allocate money; this is obvious鈥.

on the death of Russian opposition leader Alexei Navalny, Joe Biden stated that there was 鈥渘o nuclear threat to the people of America or anywhere else in the world with what Russia is doing at the moment鈥.

Orbital debris
Space is already crowded with human-made objects and anti-satellite weapons can make the situation much worse.

The president added that there was 鈥渘o evidence that they have made a decision to go forward with doing anything in space either鈥. If Moscow did decide to go ahead with the programme it would be contrary to the which 130 countries have signed onto, including Russia.

The treaty prohibits 鈥渘uclear weapons or any other kinds of weapons of mass destruction鈥 in orbit or stationing weapons in outer space 鈥渋n any other manner鈥. Anti-satellite weapons are nothing new. to destroy a non-operational weather satellite in January 2007.

While the temptation to launch a nuclear strike in space may seem alluring to nations looking to challenge US dominance in the domain, such actions come at huge risk. It is not necessarily the destruction of objects in space from Earth that should be the primary concern when it comes to anti-satellite weapons more generally, but the effect they have in space.

<91日韩AV>Mass of debris

The destruction of any celestial object creates a mass of debris varying in size from a few millimetres to several centimetres. Currently, there are hundreds of millions of tracked pieces of space debris orbiting .

The speed at which this space debris is travelling makes it a major hazard to other satellites and entities in space such as the International Space Station (ISS), which has to change course in order to avoid collisions which can cause widespread damage. The ISS has had to .

Once space debris has been created, it is almost impossible to control the trajectory after the strike or the orbital pattern it will take around the Earth. This can put a nation鈥檚 space assets 鈥 such as its satellites 鈥 at the same risk of destruction as that of an adversary. This situation has been described in similar terms to that applied to nuclear weapons on Earth, .

If a nuclear strike were to be conducted by a nation in space with the intention of destroying satellites and also to demonstrate both an ability and willingness to use nuclear weapons more generally, it would be next to impossible to control the consequences of such an action.

It would be fairly certain that such a strike would have the intended effect in reducing the space capabilities of an opponent. For example, an attack on US assets could disable the satellite-based global positioning system (GPS) that is relied on by western nations.

There is, however, the very real possibility that it would also destroy the space assets of the nation behind the attack, as well as allies and friends of that same nation. This could lead to tensions being raised and lead to a loss of that country鈥檚 support.

The inability to control the effects of attacks in space, whether they originate from a weapon in space or on the Earth, makes such actions subject to a great degree of consideration and debate in all nations that are active in the space domain.
