Disappointment of first rocket She Ji's people will launch Korea next year KSLV

Sun Ye flying Zhang Yuxiang

2009 was destined it seems that on August 25 is Korea spaceflight industry " sad day " . After be deferred 7 times, korea first carrier rocket " collect old " date is bearing the weight of Korean " dream of cosmic powerful nation " fly to aerospace eventually. However, the rocket blasts off only after 70 minutes, korea authorities announces " collect old " date fails to enter cause course, blast off " the part fails " . Subsequently, han is in about respect cognizance satellite aerosphere burn down.

Technical breakdown causes emissive failure

"Collect old " number full name is " Korea spaceflight is locomotive implement " , the two level that constitute by engine of one class liquid and engine of 2 class solid carrier rocket, one class rocket offers a technology to help by Russia and make, 2 class rocket is made independently by Korea.

Korea respect expresses, the satellite fails because rectification cover has a side to fail to open,the reason of orbit is, and two commutate cover is heavier than the satellite fourfold, this makes 2 class rocket sends the satellite without enough thrust book orbit. "Collect old " date should be in originally the 306 kilomet most popular selling hans wilhelm ers headroom after leaving the ground 9 minutes is detached " satellite of science and technology 2 " , but depart in 340 kilometers headroom however, the satellite fails to enter normal course successfully.

dvd discoveryIn addition, also Korea expert analysis says, as a result of,launching occurrence issue this may be " collect old " 2 class rocket is in date the problem appears when moving appearance. Generally speaking the satellite was not entered book orbit, as a result of,the likelihood is this reason. Also be to measure likely additionally control occurrence problem.

"Collect old " She Ji's people is exceeding and disappointed

Before this, korea is high-key all the time allege, "Collect old " if date rocket launchs a success, korea will become the 10th " use indigenous technology to send aerospace the satellite from the rocket on him land " country. Han intermediary also points out, this will indicate Korea grows from now on for " cosmic powerful nation " .

Especially Korea also hopes to take the opportunity make clear, the aerospace science and technology of Korea is not as wrong as Korea, but project a result finally however things go contrary to one's wishes, the dream of spaceflight big country of Korea also suffers the blow of certain level. Accordingly, this lift up or let down with a rope became enough after the emissive failure of people appetite, the disappointed mood of Korea people is different from general, criticize incessant also Yu Er to what blast off this, even somebody is direct so called " the part fails " accusing lead a layer at Korea. Nevertheless, blast off this to also let people see the Korea significant progress in spaceflight respect and development potential.

In fact, korea rises from 1989, begin to manufacture sounding rocket and carrier rocket. Undertake KSR successfully 1993 - of rocket of sounding of 1 solid fuel first test-fly; Launched first liquid fuel again in November 2002 KSR of rocket of 3 class sounding - 3, heretofore undertook sounding rocket blasts off for many times in all, show Korea is preliminary already have the capacity that fires different type carrier rocket.

In addition, since 1992, korea still launched 11 satellites, but it is to pass a foreign country to production rocket blasts off and enter the space from abroad emissive base. From " the satellite that in us territory launchs us with our carrier rocket " in light of this, this " collect old " of date although fail,blast off, but to Korea character, still have the great sense of milepost type.

spring pool"Cosmic powerful nation " the result that is not a day

Korea president Li Mingbo says after know projects a result, "Collect old " of date launch the success that acquires an in part. "We should be more strenuous hard, trying 8 times to return no matter is 9, the dream that must realize cosmic powerful nation " , he states Korea should jump over defeat to jump over brave, "Dream of cosmic powerful nation " will continue.

Actually, the development with respect to means of d resealable bags for clothes elivery, korea at 20 centuries the spaceflight that begins to invite the nation such as Russia and France at the beginning of 90 time is versed in Cheng expert, help rocketry of its research and development. In last few years, momentum of Korea spaceflight development is stronger, martial spaceflight project is intense, rolled out ambitious spaceflight to develop a plan, this plan is included a lot of the spacefli the most popular dearfoam slipper ght project related to the military affairs.

Look from current condition, korea will divide a phase to develop rocketry above all. Development of the first phase goes Korea " spaceflight carrier rocket " - 1(KSLV - 1) . This hans wilhelm best buy rocket and Russian conspicuous Lu Ni cut center of husband country spaceflight to develop " Anjiala " rocket cardinal principle is same, locomotive ability is 100 kilograms, namely current " collect old " date, han plans to build 10, among them two will be used at launching an experiment, 1 is used at launching moonlet, of the others use at the ground to experiment. The 2nd phase arrives 2010, development goes the KSLV that can launch 1 ton of heavy effective load - 2. The 3rd phase arrives 2015, development goes the KSLV that can launch 1.5 tons of heavy effective load - 3, final implementation uses the emissive establishment of home, rocket that uses Korea to make to serve the target of aerospace Korea satellite.

While development perfects rocketry, korea plan uses the 2nd KSLV this year - 1 rocket blasts off have a series of satellites such as atmosphere, marine observation and communication function; 2010, emissive KSLV - 2 carrier rocket, carry the homeland that weighs 1 ton muti_function satellite. After 2011, excel of resolution of e resealable bags missive remote sensing 0.5 meters optics becomes the radar that resembles satellite and rice of resolution excel L like the satellite. The plan arrives 2015, make Korea enters world spaceflight the cavalcade of home of 10 powerful nation. But " collect old " the failure of date, to its we return geometry of spaceflight plan influence wait and see what happens.

Quicken contention of domain of martial spaceflight force

Korea spaceflight starts later, spaceflight dearfoam slippers equipment technology is used at martial utility later. Regard an economy, science and technology as the country that develop, korea expects to powerful martial actual strength will protect his home, contend for on international arena through powerful national actual strength " speech counterpoises " .

From theoretic look, korea air force differentiates empty intercrop battle 3 kinds of means: It is control space, use existing aviation force and missile, surveillance of development space target, dog, identify, inchoate early-warning ability, ensure the authority that make a day. 2 it is to assist Liu Hai to fight for nothing, use orbiter to offer navigation, communication, scout and atmosphere to assist to land sea air force. 3 it is to direct a space to fight, fight to dimensional weapon make known to lower levels instruction, carry out attack to hostile satellite or ground honor award.

Accordingly, no matter be development rocket, still launch a satellite, it is the important segment that Korea quickens martial spaceflight domain to contend for. Going up early century end, korea air force was made " construction of strategic air force develops a program " , put forward to develop " strategic air force " conception, its core is to try hard to become construction of Korea air force force of an aerospace unifinication. According to this one program, the martial spaceflight force of Korea is built will with was a bound 2015, cent pace is carried out, the first pace is built before 2015 " system of base of empty intercrop battle " , the 2nd pace is built " capability of empty intercrop warfare " .

After entering new century, make national security and martial strategy increasingly as the space " commanding elevation " , korea also quickened the pace that spaceflight grows. The martial spaceflight power that boosting at present for effectively management and control is bui the most popular resealable bags lt, han Jun is advancing those who establish directly under air force actively all the time " spaceflight headquarters " , plan to establish group of empty intercrop battle before 2015, be in charge of undertaking administrative to satellite of Korea military affairs, build ballistic missile early warning system. After building " spaceflight headquarters " the main component that will make system of base of empty dearfoam slipper size intercrop battle.

Prospective development still needs to seek cooperation

watch case

It may be said of Korea development rocketry is elaborative. But when this one project formal 2002 in the begining, the United States that regards spaceflight as powerful nation does not wish to be however " ally " provide a help.

Long-term since, american government fights Korea developing development rocketry alone all the time. Look in the United States, once Korea mastered the aerospace science and technology such as rocket satellite independently, can use the martial field such as missile very easily, such sequential certainly will causes northeast inferior martial race. Face the heavy obstacle that the United States installs in aerospace domain, korea can be retreated only and cooperate with Russia.

The contrail that more than 10 years from Korea spaceflight develops looks, its are main the characteristic cooperates through inside and outside namely, digest absorb, drive oneself spaceflight industry to develop.

It is to straighten spaceflight to develop system. Since Korea aerospace academy held water 1989, korea government begins resource of spaceflight of progressively and integrated home. Promulgated early or late " cosmic development promotes a doctrine " , established national universe committee, center academy of Korea science and technology and limited company of boat world industry to wait for orgnaization of more than 10 scientific research, large company to undertake associated research and development.

2 it is to stem from start late, even the level is high, korea government chose " lend chicken unripe egg " development route. Take company of place of courtyard of gov most popular selling dearfoam slipper ernment, scientific research, war industry 3 legs walk, especially company of the country such as Russia, India and European space development has as big as martial spaceflight state clasp, carrier rocket of use foreign country launchs native satellite, in order to assure the need of folk and martial application.

3 it is clasp of unit of production of equipment of government, army and spaceflight scientific research, spaceflight, joint management, division of labor is fulfilled, make civil union of as organic as project of spaceflight of for military use ground rises.

Current, research and development level still are in the spaceflight of Korea to learn and be modelled on the phase of product of exotic nation spaceflight, short-term inside still cannot develop product of system of medium, large spaceflight independently.

But because Korea is in,electronic industry, material and treatment, optics and accurate instrument are made and the domain such as chemical industry mastered advanced technology, have the good base that expands spaceflight industry consequently. In the meantime, korea army needs to enhance the ability of the respect such as reconnoiter, surveillant, early-warning, decrease even or break away from the dependence to the U.S. Army.
