Korea of own technology excel, blast off to fail however first

Korea first carrier rocket " collect old " name experience is deferred 7 times after blasting off, entered the space on August 25 eventually. When beginning to celebrate with the people in Korea media, courtyard of Korea science and technology comes out however bad news, say " collect old " the satellite that date carries fails to hans wilhelm best buy enter book orbit, blast off to be able to be only " the part is successful " . Korea expert emphasizes his rocket and satellitic technology surmounting Korea dearfoam slippers for women in the round again and again before this, but the fact makes clear his " space navigation big country " the way is very long still.

　　 The satellite is in aerosphere burn down

Korea published the account of emissive failure on August 26. According to Korea " Korea daily " website report, jin Chongxian of the 2nd official is in ministry of educational science and technology say on the press conference: "Han Russia is collective the preliminary conclusion of board of inquiry is, ' collect old ' in order emissive process one extremely, 2 extremely arrow of rocket depart, star is detached be a success, satellite of science and technology fails to enter target orbital reason to depend on launching earlier satellite commutate the cover is detached and unusual. Satellite of science and technology fails to enter target orbital reason to depend on launching earlier satellite commutate the cover is detached and unusual..

Accord the most popular dearfoam slipper ing to investigation, in " collect old " date enters the space 3 resealable bags for food minutes the satellitic commutate cover after 36 seconds breaks away from a process in, only a side is broken away from normally, another side still adheres to going up upright, this kind of condition lasts to the satellite the 9th minute detached all the time. Jin Chongxian says: "The satellitic commutate cover that appears in the first phase is detached and unusual the angle that brings about uncontrollable rocket, the weight that the commutate of star of odd flank guard that fails to depart overspreads also brings about a satellite unavailable enter target orbital speed. The weight that the commutate of star of odd flank guard that fails to depart overspreads also brings about a satellite unavailable enter target orbital speed..

"Collect old " date at 25 days 17 when blast off enter the space, after 2 class rocket ignites successfully, korea home thinks generally to blast off gain a success; However mere after a hour, korea teachs An Bingmo of official of minister of science and technology to announce the satellite fails to enter cause course. t mobile prepaid cards

According to speculation, "Satellite of science and technology 2 " after reaching 387 kilometers height, drop because of having the rate that orbit place wants into aerosphere burn down. Piao Zhengzhu of chief of department of career of system of carrier rocket of Korea aerospace academy says: "The satellite loses centre of gravity to fail orbit, falling the probability when the earth is overall already by burn down. Falling the probability when the earth is overall already by burn down..

　　 Own technology exceeds Korea

Be in " collect old " before carrier rocket launchs mark, korea media ever interviewed many space navigation expert, undertake comparative to the carrier rocket technology of Korea and Korea. Korea expert expresses general and self-confidently, although Han Chaoyun carries roc most popular selling hans wilhelm ketry to result from Russia, but Korea blasted off in April " galactic - 2 " what carrier rocket uses name is to go up century the technology of 70 time, and Korea " collect old " what date uses is " brand-new technology " .

Report of Han couplet company says, controller of center of Korea space navigation once expressed, "When the carrier rocket technology of Korea already was passed, and of the space carrier rocket of Korea aid pushed system and other unit to had reached world-class level. " he thinks, korea space carrier rocket uses to aid turn engine, can produce 170 tons thrust, and Korea is used improve " hole of big river mouth 2 model " missile, estimation needs 4 thrust to offer motivation to just can enter the space for 30 tons engine.

Korea space carrier rocket is about 33 meters long, weigh 140 tons, those who compare Korea " hole of big river mouth 2 model " missile is big, "Hole of big river mouth 2 model " missile is about 32 meters long, but weight is 75 tons only. Of the H2A carrier rocket that Korea space carrier rocket can be the same as Japan allegedly and France " Aliyana " carrier rocket is rivalled.

　　 "Korea spirit " be worth to draw lessons from

Orgnaization of Korea country space navigation an expert also approve of this kind of viewpoint. He says, korea thinks to have the most top class rocketry in the developing country oneself, so Korea also can say to obtain giant leap in space navigation domain, because of the first class besides the rocket, others leans research and development of Korea proper motion, it is complete make from the beginning.

Kor the most popular hans wilhelm ea scientist is avowed still precede likewise in satellitic technology domain Korea. This second blast off " satellite of science and technology 2 " and blasted off 2006 enter the space " Alilang 2 " satellitic technology level is very high, "A Lilang 2 " the high resolution camera that still carried Korea and Isr most popular selling dearfoam slipper ael to be developed jointly. Still public figures of some group of Korea space navigation express, of Korea " bright star 2 " the satellite is equivalent to China only going up 70 time launch the century " east is red 1 " satellite.

Jin Chongxian alleges at that time to blast off on press conference of 26 days " rectification cover departs successfully " undertake explaining, he says: "This is the illusion of spot announcer, think rectification cover is already detached by accident. " " Korea daily " dearfoam slipper size the comment says, ministry of educational science and technology and Korea aerospace academy are below the circumstance that knows perfectly well commutate of emissive initial stage to overspread detached failure, the press conference is held to announce after a h the best selling resealable bags our " emissive failure " before, still celebrate oneself " blast off successfully " . Will look from this bit, afore-mentioned exculpatory lack conviction.

Analytic personage says, "Collect old " before carrier rocket launchs mark, the rocket of public figure of group of Korea space navigation and Korea and satellite vie blindly, it is overconfident apparently and hopeful. The carrier rocket of Korea starts should antedate Korea, the look is direct to Korea " buy " Russia is aided push a rocket, korea pays attention to ability of native proper motion research and development more, "Immerse oneself in hardworking " mental instead is worth Korea to draw lessons from.
