What you hear the phrase "space war", it is easy to conjure image that could have come from star wars movie :dogfights in space, motherships blasting into wrap speed, planet killing lasers and astronauts with ray guns.
Just as easy to dismiss the whole thing as nonsense. It's why last months call by president Trump for an American 'space force', which he helpfully explained was similar to the air force but force space,was met with a tired a eye roll from the most.
Space war is inevitable because today's modern militaries use space for everything, from spy satellite to a soldier on a mountain top using satnav to figure out exactly where he or she is. "The reliance upon space is truly extraordinary in contemporary conflict ",said Schimitt. And in any war,one side will seek to deprive the other of their ability to function. In this day and age,that means attacking the satellites.
Space wars may not involve intergalactic empires or space craft zapping each other.If they occur they are likely to be focused that matter hugely to all of us - satellites. With end of the cold war and continue development of satellites and electronics technology, attention was focused on space as a supporting theater foe a conventional warfare. Currently military operations in space primarily concern either the vast tactical advantages of satellite-based surveillance,communications,and positioning system or mechanism used to deprive an opponent of said tactical advantages.
Accordingly, most space-borne proposals which would traditionally be considered "weapons"(a communications or reconnaissance satellite may be useful in warfare but isn't generally classified as a weapon) are designed to jam,sabotage,and outright destroy enemy satellites,and conversely to protect friendly satellites against such attacks.
Space-Based Lasers
Light Amplification by the Stimulated Emission of radiation pumps energy into molecules,creating an electronic state that releases energy in the form of photons.The photons pass by other molecules, spreading energy, making more photons. To make an actual laser , a beam has to pass through mass quantities of laser medium by bouncing back and forth between mirrors placed at opposing ends. Then the light beam exits through one of the mirrors which is more transparent than the others . Making a functional laser requires the electrons to not reach their excited state , but is reliant on the time it takes for them to get excited, and also the time for the energy created to reach new electrons.
The efficiency of the laser relies on the amount of heat that exits. In terms of lasers,the power of the laser far outweighs the chemical efficiency . Of course the trajectory of the laser matters as well as its ability to hit the target it is aimed at, but when lasers are placed in space, Diffraction can cause interference.
Space Warfare in Fiction
Space warfare is a staple of science fiction , where it is portrayed with a wide range of realism and plausibility. Fictional space warfare includes anticipated future technology and tactics, as well as fantasy-or history-based scenarios that happen to take place in a science-fiction setting.
