Introduction To Space Technology Information Technology Essay

Introduction To quadriceps Technology Information Technology EssayWithout them, lacuna geographic expedition would be im feasible. Rockets and quad shuttles friend point people to quadriceps femoris. beam telescopes and quadruplet grades help people explore quadruplet. They excessively help us netherstand piazza better by taking pictures of stellar objects. The ISS International blank shell Station has begun constructed in 1998.It will house up to 700 astronauts with a connection of modules as two footb in all fields. There major part similarly be a broadcast that fire take pictures far beyond what we keep up today. (1) passing real quadriceps femoris technologies atomic number 18 necessary to make possible some potential space activities and to s sportsmanlike the cost and improve the performances of others. The National Aeronautics and aloofness Act of 1958, which created the NASA, directed the Agency to accomplish the Nations well-behaved lay Activiti es to contribute signifi bottomlandtly to the preservation of the role of the go about together States as a leader in Aeronautical and billet Sciences and Technology. (2)We all know the importance of major planet based engineering in our fooling lives as well as conventional military hard ware. After the cold war the discipline of sends and electronic warfare engineering enter into force of al around e very field of conventional warfare. The recitation of transmit technology primarily concerns and tactical advantages based on orbiter surveillance, converse affect the opponents in conventional war. The problem of poor visibility or bad wear does non affect send weapons such as joint direct munitions (JDAM) and joined stand off weapon (JSOW). These weapons rear be deployed in all weather condition without the need of every estate support it works upon GPS. organic evolution of Pakistans space platformThe Space and Upper Atmosphere enquiry Commission (SUPARCO) also k n sustain as the Pakistan Space Agency of the Pakistani g all overnment, amenable for nations public space program. SUPARCO was established on September 16, 1961 by the order of President Muhammad Ayub Khan on the advice of its founding director, Abdus Salam. (3)HistoryPakistans mission to pursue peaceful space technology began in the previous(predicate) 1960s.It was Dr. Abdus Salams advice to the president of Pakistan to establish a National Space Agency of Pakistan. It was stubborn to mark up a committee dealing with Space Sciences. A Space Science Research Wing of the Pakistans Atomic Energy Commission (PAEC ) was established through an Executive order of the President of Pakistan operate Ayub Khan which was addressed to Dr.I H Usmani , the chairman of PAEC . The program of rocket engine firings was entrusted to the chairman of PAEC. (4)Dr. Abdus Salam was appointed its first chairman.On June 7 1962, under the leadership of Air Cdre. Wladyslaw Jozef Marian Turowicz, a two spot rocket, Rehbar-I was instaled from the Sonmiani Satellite arrange Center. Pakistan was the third country in Asia and the tenth in the world to conduct such a proveing. (5) The United States douse first rocket from Pakistani soil. The erect employ the combination of two US rocket motors the NIKE CAJUN shewed from Sonmiani, 50 Km west from Karachi .( 6 ) The rocket reached an elevation of almost 130 Km. The US Space Agency NASA hailed the immerse at the beginning of a program continuing co-operation in space seek of mutual interest. The NASA SUPARCO co-operation agreement called for the training of Pakistani scientists and technicians at Guddard space flight rivet and Wallops Island NASA also set up look into associates and fellowship programs at American universities. In 1981 SUPARCO planed Astronautic program with NASA. But referable to the space shuttle challenger incident the program was put on hold. Later it was cancelled in 1990. (6)On 8 March 1966, Presiden t Ayub Khan constituted SUPARCO as a separate organization. Dr Abdus Salam , a ample with Dr. W J M Turowicz, led a team of aerospace engineers and rocket scientists to design a Rehbar sounding rocket series.(7) Dr Abdus Salam also established space centers in different cities of Pakistan similar Karachi and Lahore. He also initiated an aerospace engineer program in SUPARCO. He was one of the pioneering figures in the 1960s to lead Pakistan in the space power world.He knows the importance of space and nuclear technology his efforts were also involved in the culture and deftness of high powered astronomical telescope at Karachi University. He also established aero space engineering science course at PAF Academy.(8) Though the Pakistani space program was frozen several ages same(p) in 1970s, by the government of Pakistan , President Yahya Khan and PM Zulfiqar Ali Bhutto froze it more than a decade past again in 1993s both nuclear and space program due to economic depression. T his space program was defreeze by then President General Pervaiz Mussharraf and the agency developed a send schooling program rapidly but on the other hand Indian space Research organization(ISRO) progress very well as ESA, NASA and Chinese space agency. SUPARCO faced strict sanctions on the import of various materials required to manufacture and tack rockets during early 90s from USA and Russia. The delay of Russian make fomite also resulting the long delay for the launch of Badr B, Pakistans second planet, These events had an immense impact on SUPARCOs plan to launch and place its own beam in subject. (9)Beside the talented space and nuclear scientists Pakistan followed the policy of deliberate ambiguity for many decades. Thats wherefore its thus far unclear what the plans and operations as well as the electrical capacity of SUPARCO and its facilities are?Comparison of Pakistan and India space programBadr -1SUPARCO with the help of Amateur Radio Society started building t he piffling Amateur radio air in late 1986. Badr -1 was planned to be launched on the US Space Shuttle, but Challenger flare-up and consequent delay in American flight changed the plan. (10)Badr -A was Pakistans first indigenously developed beam and was launched from the Xichang onager Center, chinaware on July 16, 1990 aboard a Chinese Long March 2E rocket. Badr- 1 weighted one hundred fifty pounds. It was intentional for a circular orbit at 250- 300 miles altitude, the major planet successfully completed its designed life. (11)Badr -BPakistans second satellite was Badr -B .It was an reality observation satellite and was launched on 10 December 2001 on a Zenit 2 rocket from Baikonur Cosmodrome, Kazakhstan. It was designed by Space Innovations Limited from the UK. (12)Pakistan has only operated one bantam satellite in LEO the countrys modest space program has long been leaning toward remote perception applications. A information processing infrastructure has been establi shed to exploit earth observation data transmitted by Land sat, NOAA, and SPOT satellites. Further SUPARCO is preparing for the commercial launch of a simple Pakistani satellite with earth imaging capabilities.It was expected that SUPARCO would launch the second Badar -II satellite in1993 but target was not achieved. The Badr -II will help Pakistan in making of infrastructure for space competent body and achievement of know how and capability in the field of satellite attitude control. (12)PakSat-1PakSat-1 was Pakistans first geostationary satellite. The satellite was initially known as Palapa C1 and was designed to serve Indonesia after an electronics failure, it was renamed Anatolia 1 and then renamed again to PakSat-1i in 2002.it was originally manufactured by Boeing and used the HS 601 space business deal design. It was launched on February 1, 1996. (13)PakSat-1 currently severing a number of regional customers including, TV broadcasters, telecom companies, data and broad band internet function returnrs as well as government organizations. PakSat-1 will be switchd before its end of life by PakSat- 1R to ensure continuity of service. (14)PakSat- 1R SatellitePakSat- 1R Satellite will replace the existing paksat -1 in 2010.under the agreement Telesat will help the Pakistani agency find a manufacturer, expert and commercial advice and also to help supervise the construction of new satellite and proctor the launch and in-orbit exam services.Haft Ballistic missile ProjectDespite of space program SUPARCO initiated Pakistan nuclear missile development program in early 1980s.scientists from KRL and SUPARCO developed colaboratlly Haft missiles series. It was reviled in 1989.with the successful launch of an indigenous multi stage rocket into the deep space. Which was verbalize 480 Km deep into the space. Recently SUPARCO has tested two high altitude hyper sonic sounding rockets (Shaper and Rakhnum). This is claimed to be a 3 stage liquid fuel rocket and get the altitude of 1000 Km. (15)Shaheen III satellite launch vehicle (SLV)Its a 3 stage SLV and can carry the payload of 100 Kg to an orbit of 450-500 km above earth surface. (16)Indian Space Research OrganizationThe national space program was formally organized in 1972 with the formation of space instruction, the department of space (DOS) and Indian space organization (ISRO) to promote the development and application of space technology and socio economic benefit of the country. Space commission is the policy making body and these policies are implemented by department of space .research and development activities are carried out through Indian space research orgnisation.the over all co-ordination of the space program is carried out by program offices of ISRO in different areas like satellite communication, earth observation systems, space sciences, launch vehicles, international co-operation and industrial co-ordination etc. (17)Major establishments of the department of space com plicateNational remote sensing agency (NRSA) NRSA come on upd in Haiderabad is an antonymous institution support by department of space .its main task is acquisition, processing and distribution of data from remote sensing satellites.

It also provides satellite fabrication, launch services and tracking facilities. (20)Major technological programs and achievementsFrom a Modest beginning in 1963 with the launch of small rocket from ThumbaThiruvanthapuram, Indian space program has come along way. Today Indian national satellite system (INSAT)and the Indian remote sensing satellite system (IRS)are the vital elements of national infra structure for telecommunication , telly broad casting, meteorology , survey and management of resources are now designed and build indegiousnly INSAT satellite system. It is one of the largest domestic satellite systems in the world today. INSAT Systems got a substantial boost in 1999-2000 with the commission of INSAT- 2E and the planned launch of first two INSAT 3 A and INSAT 3 V of the five satellite series. It also extended C-band transponders. (21)IRS Satellite SystemsAn Indian remote sensing satellite system comprises a conformation of four satellites. IRS Satellite Systems provides remote sensing services. Data provided by these satellites is put to use for application like agricultural crop acreage and stand estimation, ground water targeting, identification of waste land for possible reclamation, forest survey snow melting, mineral prospects, thematic mapping, and ur ban planning environmental monitoring and so on.Data from IRS Satellite is also acquired and used by several other countries like Korea, Japan, Thailand, Europe and Dubai under commercial agreements. The IRS series includes OCEAN SAT, CARTOSAT and RESOURCESAT and many others.(21)Satellite Launch VehiclesISRO has made substantial progress in the development of launch vehicle.The Polar Satellite Launch Vehicle (PSLV) has already became operational with the successful launch of IRS 1.it is also plan to launch all future satellites in the IRS series by this vehicle. The PSLV is also cosmos offered other countries to launch their satellites. A beginning was made by launching IRS -P4 (OCEAN SAT) PSLV-C2 was used to launched two small satellites namely the Korean (KISAT) and the German TUBSAT as pay load.(21)Part 2Militarization of spaceSpace plays an increasing role in military activities. Over 800 satellites orbit the earth, many of which have military uses, from reconnaissance to guidi ng weapon systems. Satellites are the main focus of military activities. They are widely used to provide support for military or security related activities such as verifying compliance with ordnance control treaties. They are also increasingly used to provide direct support for military operations. During the 2004 Iraq war, 68% of munitions were satellite guided. (22)Right from the beginning satellite has an important military role during war m as well as in peace time.dependance on them is increased dramatically in last two decades. The previous methods of reconnaissance, communication, remote sensing etc are largely responsible for increasing role of military satellites. slightly of the most commonly military satellite applications areReconnaissance and intelligence garner functions. control and communicationNavigation satellitesEarly warning satellitesMeteorological satellitesNuclear detection satellites (23)1 Reconnaissance and intelligence gathering functionsThe most known types of military satellites are these used to verify the extant and the composition of military forces. The most important role of Reconnaissance and intelligence gathering satellites is the verification of the agreed limitation of strategic fortify and monitoring of new military developments. It is achieved by a variety of electronic and photo graphic means.Command and communicationCommand and communication is one such application the satellites today meant for the purpose can provide instant communication between the operational forces and their national command authorities irrespective of the distance or time of the day. (23)Navigation satellitesThe Navigation satellites are adequate to(p) of providing data to enable position fixing with an true statement of few meters.Early warning satellitesThe role of these satellites is to detect the exhaust of rising ICBMs. These satellites carry large telescopes and television cameras to transmit photos of detected ICBMs.(24)Meteorolog ical satellitesUses of these satellites like weather forecast have been earlier benefits of space program. The weather satellites not only provide long range forecast for military planners, they also play a key roll in reconnaissance satellites. They provide advance information to the mission planners of reconnaissance satellite on whether the target area will be clear of clouds cover or not. When the reconnaissance satellite makes its plan, this eliminates the wastage of reconnaissance film.(24)Nuclear detection satellitesThe idea of nuclear detection utilise satellites originated by USA. While conclusion ways to police a nuclear test ban treaty. The solution came in the form of Wela satellites. This has the capability of detection a nuclear explosion at the distance of Venus or Mars and reports its yield and other characteristics. What now after 1970 IMEWS (integrated missile early warning satellites) had taken over its place. (24)How India can weaponise space to effect conventi onal and strategic forcesISRO opposed military applications for duel use projects such as SLV3, (satellite launch vehicle- 3) .Ultimately the defence research and DRDO based missile program headed by Dr. Abdul Kalam who was the project in charge of SLV3 at ISRO, DRDO borrowed him with other scientists and other technology resources from ISRO directly for Indian missile program at DRDO where Dr. Abdul Kalam designed the Agni missile using the SLV 3 solid first stage and liquid fuel second stage (Prithvi Missile derived).IRS and INSAT were mainly intended and used for civilian economic purposes. They also offered military spinoff in 1996.ministary of defense reaction impede the use of IRS 1 C by the Indian environment and agriculture ministry in order to monitor ballistic missile near Indian borders.Indian air forces doctrine also aspired to use space assets for surveillance and battle management. (25)Satellite navigations allow precision in the delivery of weapons targets, increas ing their lethality. Satellite navigations can be regarded as a force multiplier. Satellite navigations also allow forces to be directed and locate themselves more easily in the fog of war.According to the report by IANS February 9th 2010 India is developing an intelligence satellite for detecting conversations and espionage activities. According to Defense electronics research laboratory (DERL) Rupees 10 one million million has been allocated in for this project in cooperation with ISRO. The satellite will be fitted with the electronic sensors are more powerful than the remote sensors satellites of ISRO. Space craft should be ready to launch by 2014.Anti-Satellites WeaponsAccording to a TV press briefing during the 97th Indian science conference the director general DRDO announced that India is developing lasers and Exo-Atmospheric Kill Vehicle that would be feature to produce a weapon to destroy enemy satellites in orbit. (26) Later in February 10 2010 DG DRDO and Scientific adv isor Dr V K Saraswat said that India has all the building blocks necessary to integrate an anti- satellite weapon to neutralize the hostile satellites in low earth and polar orbits. He also said that the propulsion module and kill vehicles already existed in principle on the Agni missile series .he also said India doesnt had a formal anti-satellite weapon as yet, however anti- satellite weapons could be developed as the part of Indian Ballistic missile program which would be completed in 2014. (27) India also identify development of antisatellite for electronic and physical destruction of satellites. In both LEO and the higher GEO co-occurrent orbits in its long term prospective plans (2012-2027). (28)Launch capabilitiesGeopolitical and economic positions during 1960s and 1970s laboured India to start its own launch vehicle program. At its first days from 1960-70 India successfully developed a sounding rocket program. (29) By the 1980 the search yielded the satellite launch vehicl e 3 and the more advanced(a) augmented Satellite launched vehicle (ASLV) completed with operational supporting infrastructure. ISRO applied its capabilities and resources for the advancement of launch vehicle technology resulting in creation of polar satellite launch vehicle and geosynchronous satellite launch vehicle (GSLV).1 Satellite launch vehicles (SLVs)SLV was a four stage solid fuel light launcher. It was intended to reach the height of 500 Km and can carry the pay load of 40 Kg. (30)Augmented satellite launch vehicle (ASLV)It was a five stage solid propellant rocket with the capability of placing a 150 Kg satellite in to LEO.THIS PROJECT WAS STARTED BY THE ISRO in early 1980s for the pay load to be placed into geostationary orbit. Its design was based on SLV afterward it was decommissioned in 1994. (31)2 Polar satellite launch vehicle (PSLV)It was an expandable launch system developed to launch Indian remote sensing satellites into sun synchronous orbits .PSLVs can also la unch small satellites in geostationary transfer orbit (GTO). The reliability of PSLV is proven by that it has launched 30 spacecrafts 14 Indian and 16 from other countries into a verity of orbits. (32)It also successfully launched 10 satellites at a time in April 2008 by making a new world record previously held by Russia. (33)3 Geo synchronous satellite launch vehicle (GSLV)It is also an expandable launch system to enable India to launch its INSAT type satellites in to the orbit by making India less depending on other foreign rockets. It is the ISROs heaviest SLV which is capable of five tons payload to low earth orbit. (34)4 Geo synchronous satellite launch vehicle Mark III (GSLV)It is a launch vehicle under development by ISRO which is capable to launch heavy satellites in geostationary orbits. Due to this development India will become non dependent for heavy lifting on foreign rockets. Its first flight is schedule in 2011. (35)Satellites launched by South Asian CountriesTill 200 8 India launched 34 satellites indigenously or by other countries help. On the other hand Pakistan has launched 5 payloads in the orbits. Where as china has launched 83 payloads. (36)Areas of concernIn December 2006indian defense establishment conducted the first test of its missiles defense capabilities, in which an interceptor PAD destroyed a Prithvi SRBM at a height of roughly 50 Km. DRDO tribal chief M Nataranjan stated that it was a major achievement of India although he acknowledged it would be some time before India might possess an anti-satellite capability.(37) Following the PAD anti-missile test, India conducted 13th test of BrahMos cruise missile. However it has not been able to develop a military satellite for the arm forces, along -standing demand of the latter. The military satellite projects world developed in cooperation with ISRO (38)When India will achieve its aims of armed forces military satellites that would be a highly vulnerable time for Pakistan.How Pakista n can respondPakistan is surrounded by two symbiotic (China India) and also Iran who is assay in missile and space program. These countries have affected missile systems and satellite networks. To counter with these elements Pakistan must have an effective missile delivery system as well as effective missile defense systems. Both of these systems could not achieve the maximum results without any military satellite network. Reconnaissance and spying of the ground based troops, their movements and jamming or intercepting enemys network. All these elements based on spy satellites. To monitor the launch of enemys ballistic missile we should get thermal imaging capable satellites. In modern warfare systems all the trio services should be interlinked with the battle fields with the help of sensors radars and communication satellites for the early warning and central command and control. Smart weapons like JADAMs their acquiring will be an asset for air force in this valuable race.Part 3Economic effects of space race between India and PakistanThe ISRO will receive 57.78 one million million million rupees ($1.25 bn) for 2010.its a 38 % increase over last year. 21 billion Rs will go to launch vehicle technology development while satellite technology will receive 10 billion Rs, a 45 % increase over the 2009 fund.(http//www.space.com/news/india-space-budget-increase-sn-100315.html)Budget of SUPARCO in 2009 was 3.12 billion rupees for its four on going projects in the next fiscal year.Rs 1.764 billion for PakSat-1R. Rs 100 million for the development of environment constitution and testing (EVT) Satellite. Rs 84 for intelligence development and capacity building in satellite engineering and technology etc. (39)Both (India Pakistan) are the nations with one of the poorest populations in the world who are investing billions of dollars into space missions and satellite launches. Instead to over come the poverty both are neglecting the core issue.Pakistan has no compari son with India in space race and without a doubt Pakistan can not afford the space race.How Indian developments are being seen by international world especially China and USAThe India Space Program considered being a sign of an Indian effort which can maintain some measure of equality with China on the world stage or to create its own claim to great power status. Because its still behind China. There has been increasing debate of an Asian space race among China, India, and Japan to explore the lunar surface. India has over 40 years of experience in space and has achieved a comparatively strong and mount capability in space applications. In technological terms, Indian space program is roughly equal with Chinas program except in human spaceflight and exploration. While India spends a bit more than Russia does on its space program. The percentage of GDP that India devotes to space is second to USA. India moves to advance internationalize space exploration and any cooperation with USA or Russia, will have a major impact on space exploration throughout the next decade and beyond.Although India cant have strategic parity with China, but the Chinese ASAT test has highlighted a new Indian vulnerability, as the country is about to develop in approach shot years modern military observation and communication satellites. Conflict between India and Pakistan, with the potential of nuclear armed missiles exchange remains a source of international concern. In such conflict , to de-escalate the crisis China can provide reconnaissance to Pakistan, of Indian troops movements and mobile- missile deployments would be crucial for india. While using its ASAT on behalf of its ally to blind India could be a serious concern for India. To counter these threats India can seek reinforce intelligence ties to USA and Russia to use their capabilities which China might be reluctant to target. (40) completionAs the comparison of India and Pakistan we can clearly see that Indias space and nu clear program is going by every means. Whether it is spying satellites or deployments of other countries spy satellites like Israel or its anti- satellite programs. All these areas of concerns destabilized the truth of Pakistan as well as other countries like Iran and China.International community can create bar in permissions and clearances for Pakistans nuclear and missiles due to Israel and Indian influence on world community. But the thing is that India has a clear intention to advance its space and nuclear program, Pakistan will have to take countermeasures which will include deploying its own satellites and there is risks that in this respect may it provoke a space race that neither can afford.NOTES1http//libary.thinkquest.org/j0112540/spacetek/index.html2 http//www.nap.edu/openbook.php?record_id=6068page=53 history of SUPARCO4 http//www.suparco.gov.pk/pages/history.asp5 http//www.nap.edu/openbook.php?record_id=6068page=56http//www.wisconsinproject.org/countries/Pakistan/hat af.html7 http//www.nap.edu/openbook.php?record_id=6068page=58 http//www.nap.edu/openbook.php?record_id=6068page=59 history of SUPARCO10 http//www.fas.org/ssp/guide/pakistan/earth11 http//www.fas.org/ssp/guide/pakistan/earth12 http//www.fas.org/ssp/guide/pakistan/earth13 http//www.paksat.com.pk/14 http//www.paksat.com.pk/15 http//www.wisconsinproject.org/countries/Pakistan/hataf.html16 (http//en.wikipedea.org/wiki/space and Upper atmosphere Research commission17 Dr. D C Agaraewal satellite communication pg 34418Dr. D C Agaraewal satellite communication pg 34519Dr. D C Agaraewal satellite communication pg 34720Dr. D C Agaraewal satellite communication pg 35021http//www.isro.org/lahnchvehicles/GSLVMARKIII/mark3.aspx22 (POST note December 2006 273)23 Dr. D C Agaraewal satellite communication pg 35424Dr. D C Agaraewal satellite communication pg 35625 mistry, 94-9526 peter B de seldingindia developing anti-satellite spacecrafts space .com27 India developing weapon systems to neutralize e nemys satellitesXinhua Newsagency.2010-01-03.reterived 2010 -01-0328 http//timesofindia.indiatimes .com/india/india-to-gear-up-4-star-wars/articles/show/5970384.cms)29 http//www.isro.org/lahnchvehicles30ISRO vehicles.
