Speculation that Russia is perhaps growing a brand new space-based nuclear weapon has led to a flurry of debate about what's going on - and what it might imply to see army installations in area.

But area is already used for army functions. Thousands of satellites orbiting the Earth are essential to missile focusing on, fighter jet navigation and nuclear weapons management.

So is area the brand new frontier for warfare, or are the disadvantages so nice that it is simply not value it?

Sky News spoke to a few area consultants to discover the subject.

Thousands of satellites orbiting the Earth

There are greater than 8,000 satellites orbiting the Earth, and that quantity is barely growing.

"Think about how much of our everyday lives are determined by satellites in orbit," Sky News science correspondent Thomas Moore says.

"Everything from telecommunication to GPS... we are dependent on that eye in the sky. So this is going to be something that all major powers are looking at."

There are 31 operational GPS satellites, he says, of which 24 are wanted for correct positioning worldwide.

So there may be some redundancy inbuilt - a number of must be taken offline to disrupt issues on the bottom beneath.

Is area already militarised?

But these satellites aren't simply used for civilian functions, says Dr Bleddyn Bowen, an knowledgeable in worldwide relations in outer area on the University of Leicester.

Space, he says, has been militarised for many years.

"The first things that went up there were military by design, military by nature, for military purposes.

"And the majority of the area age actually is about these satellites in area, not astronauts, not the area station, not boots on the moon. They're simply sideshows.

"So the space environment, as long as we've been physically using it with machines, it's been for military purposes."

Can satellites be destroyed?

Yes. But that is not a revelation linked to the hypothesis round no matter new functionality Vladimir Putin's army is seemingly growing.

The US, Russia, China and India have all efficiently shot down their very own satellites, proving that such a factor is feasible in warfare, if it had been ever wanted.

Also, the twin use of satellite tv for pc expertise in area is "rife", says Dr Bowen. This consists of "close inspections or close flybys" of satellites by China, Russia and the US - experimenting with the potential to make use of an object in area to ram one other.

"You need to master those close orbit technologies and inspection technologies if you want to actually attack those satellites with something that isn't a nuclear bomb."

But the implications of destroying a satellite tv for pc with a kinetic (bodily shifting) weapon will be large, he provides.

"You'll create a cloud of debris that can then hit other satellites... There's no control over that."

What about different weapons in area?

That is supposedly banned underneath the UN's Outer Space Treaty, to which the US and Russia are social gathering, says Dr Sarah Jane Fox, an knowledgeable at Space Park Leicester.

She says its provisions embody the prohibition of nuclear weapons in area and limiting using the moon and all different celestial our bodies to peaceable functions.

Asked if she anticipated this treaty to carry, she mentioned: "It's an interesting one. It's held since we first went into space, so since the 1950s, with written agreement being formalised in the latter part of the 1960s.

"Warfare is altering, the domains of warfare, we have land, sea, air, our on-line world and area. The most up-to-date two, area and our on-line world, will little doubt current a problem shifting ahead."

But what if somebody was minded to disregard the UN treaty, wouldn't it make a distinction stationing a nuclear weapon in area?

Dr Bowen says: "You don't need to put nuclear bombs in space to still use nuclear weapons in space because most nuclear weapons are based on Earth. They're in missile silos, on submarines or on aircraft.

"You can modify these very simply simply to fireplace up into area and reasonably than fall again down they simply detonate in area."

Setting off a nuclear bomb in area would make a "huge mess", he says.

"You'll just have an electromagnetic magnetic pulse and loads more radiation in orbit, which will fry the electronics of so many satellites (and) possibly knock out power grids in places down on Earth."

Moore added that he was undecided how a lot benefit - apart from a diminished response time - a state may need firing a nuclear weapon from area than from a location on Earth.
