Abstract. In this ageof science and technology Space junk is increasing enormously in the result ofhuman activities in space . This does not leave those space orbits clean forupcoming space crafts or space walks.
One proposed way of reducing this debrisis the use of orbital lasers. For faster reduction four lasers are used. Laser being cheaper from others wayslike space ballons or pods and tungsten microdust etc. Cascading effect of trash bring forth more but smaller trash . So, by the time cascadedincrease and at the same time laser reduction would be analyzed. Effectivereduction would be attained by using fours laser beams at a time. Keywords: Debris(Junk or trash), Ramification(seriousresults ). Reduction (to decrease)1 IntroductionRemnant of manmade satellites and other space crafts which are sentabove in space in order to get space images or for communication etc remains there.
These human devised machines do not last forever. Like everything they have todecay and eventually come to an end. These small fragments separated either byerosional, colloidal or extinction, disintegration, defunct activities of spacecrafts, remain in orbits along with meteorites. Some remain there in space andsome ultimately fall back to earth and envelops its atmosphere. If not treatedappropriately even a minute particle of junk with rapid speed can play havoc.It is hazardous not only in satellite collision but also for Earth-livingplanet –environment.
According to European Space Agency estimation “about 75per cent of large objects launched into space have already re-entered Earth’satmosphere”. Hazardous, complex and serious consequences are caused by spacejunk and can perform different harmful activities on atmospheric pollution orspace crafts collisional disasters.Man has gone very advance in technology for his benefits , desiresand needs but this has left many consequences one of which is that our space islittered. Here question arise for its reduction .There should be some ways tosweep out the space trash just as we sweep our earth trash for the sake of ourhealth . Likewise for out more betterment , in order to send more space bodies, there should space enough for those space bodies .So agent are being declaredas small particles of junk(not the huge ones).
1.1 Collision withspace crafts Asthere are many satellites revolving around our earth in space , every country is sendingits own space crafts. Hence there are always chances of collision , not ofthese space bodies but with space trash coming from somewhere. Mostly thedefunct pieces of trash have been tracked and space craft takes anotherdirection. But we have some trash pieces enoughsmall that they cannot be seen if seen they cannot be tracked. Speed increasesin spaces and even a small particle of having size in millimeters tocentimeters can cause some disaster to space shuttles.
A small crater can bemade in machine by junk fragment which demands reparing off course. Soreduction of defunct fragment will overcome these disasters too. 1.
2 Interparticles CollisionDespite of striking with satellites these particles mayalso collide with one another . In the result of this collision they createcascading effect by tearing apart one another and generating more fragmentswhich will be relatively smaller in size . Kesseler Syndrome –one of verypopular effect proposed by a NASA scientist – isthat “density of objects in lowearth orbit (LEO) is high enoughthat collisions between objects could cause a cascade where each collisiongenerates space debris that increases the likelihood of furthercollisions” also describe same collision effect ,causes, and consequences. 2. Background and Literature Review Since the launch ofsputnik I space is being littered increasingly and it will grow more. Many junkdisposal and reduction mechanisms, techniques and machines are being designedbut none is implemented so far.
Their installment need time , they are costlyand some demand some more serious analysis. One way is to deorbit junksomewhere else where satellites could not be installed or debris are pulled byexertion of some force to turn its way. 2.1 Space Balloon: Despite of using laser concept of space is put forward in which a thin space balloonthrown in space and space junk stick to it and gradually being dragged by ittowards earth. 2.2 CLEANSPACE ONE: It is a small satellite made by a swiss person .
It have sticky jellyfishlike tentacles which grabs those stray fragments and eventually throw themtowards earth by pulling them. . 2.3 Space Pods: Space pods are also made which use power of nuclear energy to destroy spacetrash. . 2.
4 Tungsten Microdust: This is launched in low earth orbit , slowing down debris speed . Butthis is not used because of its harmful effects. And many other ways are devised as above. 2.5 LASERORBITAL DEBRIS REMOVAL : Use of laser is rather cheap and easy . Thusthis is considered so far the best way .
It has been analyzed by Cr Hips in hispaper with complete mathematics , mechanism , techs and tools . This systemalso prevent further collision as described in kesseler syndrome. But here some functionality is beingachieved by using four laser system for each direction . They will remain around orbit an preventneighbouring collision and reduce them . But disadvantage of this that it willget expensive too due to four installments of one system. But this system had never been modeledusing netlogo with respect to collision reduction and analysis with time 3 Research Question Goal is to effectively increase space littering by improvisingexisting proposed methodologies. As this cannot be tested in reality for now sosome important assumptions would be taken such as moving or colliding state ofdebris , its regular increase over time and then its decrease .
using proposedmethod . Likewise cascading effect is assumed .4 ConclusionIn the nutshell as earth is ours , space is ours too . As earthdemands to be cleaned so the space does.
This model signifies this problem andits reduction by using laser , four instead of one . This have useful effect ondebris and reduce it faster and furthercollision are proactively handled . This is feasible in launching but costmight be high . This throw of debris toearth can further be considered harmful and be studied. Besides further researchcan also be made by affiliating or incorporating laser in other reduction ways.
