On November 28, japan launched optics of a new generation successfully " data gathering satellite " . The satellitic name that blasts off this is " optical 3 " , be located in Japanese south deer at be in that day morning the center of seminal island universe of insular county takes Japanese H2A carrier rocket to enter the space. This new the optical satellite that enter the space is congener in the 3rd, belong to the 2nd acting reconnaissance satellite of Japanese, resolution by raise 60 centimeters 1 meter before. "Optical 3 " after the satellite is accepting the test of about 3 months, begin to enlist in army formally, blasted off in order to replace in March the best selling resealable bags 2003, design life to be 5 years " optical 1 " satellite.
Cast off the dependence to the United States, build independent information network
In March 2003, japan serves aerospace two emissary satellites, stride one stride to the information system that builds his, this also is indicating the change of policy of development of Japanese peace universe. Launch two emissary satellites to begin first from March 2003, japanese around altogether launched two pairs in all 4 emissary satellites, namely two optics are become like the satellite, two radar are become like the satellite. Among them, the satellite of the 2nd radar that launched in Feburary 2007 is in enter the space invalidation malfunctions after a month, and " optical 1 " the satellite also is about to reach service life. Then, japan spends about 48.7 billion yen again (add up to 560 million dollar about) research and development gives new generation satellite, this just launchs a success namely " optical 3 " satellite. In addition, japanese government still plans to launched satellite of the 3rd radar again 2011. At the appointed time, japan relies on this to cover satellitic system but specific place of the some on monitoring earth, have the capacity that monitors continuously to latent heat area.
The emissary satellite that Japan launched in March 2003 makes an appointment with 2 tons again, and the data of satellite of new generation spy that transmits this lighter, solar battery board efficiency is taller, bodily form also appears more slender. Satellite of new generation spy can identify ground diameter the object of 60 centimeters of size, can discern consequently whether does the battleplan of grounding of aircraft embark have missile, the car of discrepancy base belongs to what sort, prep let alone can differentiate to be in emissive condition or be carried with the train " hole of big river mouth " missile. Only with respect to resolution, the ability that Japan fastens all respect in aerospace information already forced continuously the United States. OK and fatidical, after satellite of new generation spy goes up to the sky, in aerospace information field, japan will rely on the United States no longer. brass faucet
Launch 34 stars 5 years, new spaceflight policy puts forward to develop early warning system
This year on April 27, japan develops strategic headquarters conference in day of begin navigation of Tokyo call together, protocol " spaceflight development uses Five-Year Plan " . Put forward to want to make information collect satellite increases by 3 current at that time it is 4, launch what plan to this just about this to fulfil with carry out. In the meantime, "Spaceflight development uses Five-Year Plan " the research that still offers Japa resealable bags for flights n to will increase technology of detector of satellite of inchoate to guiding instead early-warning, with casting off the dependence of system of its missile defense to the United States at an early date. Can say, this " spaceflight development uses Five-Year Plan " for Japanese development early warning system of day radical missile and satellite of other military affairs opened an entrance door, the dimensional science activity that also is Japan at the same time offerred funds.
Minister of headquarters of strategy of development of Japanese government spaceflight by premier minister Ma Shengtai man is held the position of. This also is this ministry from last year in May " cosmic basic law " the first when after coming on stage, make Five-Year Plan that develops about spaceflight. In this plan that forms by 9 much, increase research to be used at guiding the detector of inchoate early-warning satellite considers to be put in prominent place instead.
brass faucet" the universe plans basically " gave out in detail Japan plans to the dimensional application 2014 and development, gave out the initial program before 2020. According to this plan, japan will launch 34 satellites inside 5 years henceforth. Henceforth in 10 years, this plan suggests to begin work of the following development: Develop at least 2 " the earth " the follow-up model satellite of the satellite of mapping and calamity that monitor, develop 2~4 at the same time the small-sized satellite that has safeguard effect; Development " jade " and " stumble " high speed data passes those who be defeated by a satellite to replace a satellite; Development optics and radar satellite come to those who have support " data gathering satellite " reconnaissance satellite constellation.
Japan expands aerospace capacity clingingly
Long-term since, japan labels development space technology all the time " science and technology establishs a country " serious content of the strategy. 50 time have 20 centuries, japan begins to manufacture carrier rocket. Japan had the capacity of rocket 1958. Japan used L 1970 - 3 class of 4S solid rocket sends aerospace the satellite of date of great outlying place that weighs 24 kilogram, the country that God of the 4th implementation after becoming United States of the afterwards on the world, Russia and England dreams. Come to develop 5 set such as a L, J, M, N, H successfully already originally now 11 kinds of carrier rocket, launched more than 50 satellite, had become to have the spaceflight big state of actual strength quite.
Japan launchs a system at first, it is a foundation with design of rocket of tower of American heart Er almost. N series and the following H1 use Am hans wilhelm erican part mostly. Japan thinks, if want to become big state of Asian spaceflight big country and world technology, must have a kind of larger carrier rocket, one kind is designed by Japanese completely and the rocket that come out is made in Japanese factory. Then Japan considers to develop H2 rocket according to this one tentative idea, spent 10 years of time and the fund of 270 billion yen for this. H2 rocket is full-length 50 meters, emissive gross weight 260 tons, can send close ground orbit 10 tons satellite, or send the earth synchronous orbit 2 tons satellite. Since 1994 H2 rocket ever launched a success 5 times continuously, be regarded as Japan to produce the pride of the rocket for a time.
Begin from 1995, japanese universe develops the work of research and development of rocke dearfoam slippers for women t of H2A of career round proceed. H2A is full-length 53 meters, weigh 403 tons, can send the earth synchronous orbit the satellite of 2 tons of class. H2B ro the best selling hans wilhelm cket is on the foundation of H2A research and development, its are the biggest double what emissivity exceeds H2A dearfoam slipper best buy rocket.
The martial utility of Japanese emissary satellite makes a person anxious15 pin vga
Must see, japanese peace develops cosmic policy to producing change sadly. In May 2008, council of Japanese Boule cabinet was passed " cosmic basic law " , allow aerospace clearly to be used at martial end. This act was carried out formally on August 27 subsequently. In June, japan appoints chief aerospace to develop chancellery, and immediately establishs the universe to develop strategic headquarters, ability of positive development outer space in order to ensure the country is safe. " cosmic basic law " allow Japan to use outer space at " defensive sex " martial end, content includes: (1) allows Japan to launch the emissary satellite that has martial use and inchoate early-warning satellite, the one part that regards the missile defense that cooperates with the United States as the system its tries to use; (2) establishs premier to develop strategic this department from the universe of administer in person inside the government, macroscopical hold the universe to develop policy and make corresponding plan. This one act of Japan causes world public opinion to be anxious extensively.
Last year in November, secretariat of headquarters of Japanese aerospace universe ever protocol a draft, the aerospace universe headquarters that the proposal is in charge of making aerospace develop the strategy considers to introduce early-warning satellite capacity, in order to scout of hostile and ballistic missile blast off, promote the national defence application of rocket and satellite thereby. In addition, japan exceeds satellite of high speed Internet to blast off successfully already also. This satellite aims to offer the high speed Internet that covers Asian area to visit a service, and test and verify builds wireless freeboard fast the skill that place of network of high capacity international requires. Japanese hope future can the freeboard that work up covers Japan and Asia-Pacific part area fast communication network.
In recent years, japan is used on martial road to go further more in cosmic development, insist to perfect oneself independent aerospace intelligence system, make network of global aerospace information. Begin from 2005 in fact, japanese government decides to study satellite of new generation spy, main purpose is nuclear installation of aggrandizement surveillance Korea, make emissary satellite miniaturization, raise maneuverability further, finite to when the ground undertakes filming, be in optimal photography instant films resealable bags for food more image. Emissary satellite of Japan plans, can't help making people comes into being worry to the development direction of Japanese space technology. At present Japan already mastered the world's top-ranking solid rocketry, and solid rocket and ballistic missile are being lain between only on the technology, layer paper, japan can use existing solid rocket completely to change his costume or dress to reach intercontinental missile short distance, intermediate range, remotely.
In recent years, japan is to show the driving intention that participates in aerospace competition more. 2008, japan " hope " date experiment cabin is entered be stationed in international space to stand. This experiment cabin is establishment of first manned spaceflight of most popular selling hans wilhelm Japanese, can hold 4 people. This year on September 11 before dawn 2 when 01 minutes, airship of freight of first aerospace of Japanese -- aircraft of dimensional station transport 1 (HTV1) from southern deer the center of seminal island universe of insular county enters the space. Japan plans 2015 with annual speed launchs 7 HTV in all. After American space shuttle retires, of HTV and Russia " progress " airship, automatic freight airship of Europe (ATV) will assume a he resealable bags avy responsibility that carries goods and materials for international space station.
Can foreknow, increase what enter aerospace ability as Japan ceaselessly, the purpose that controls aerospace will be more clear, this certainly will causes the aerospace competition with circumjacent further country, should cause the high vigilance of world each country and attention. (Li Li)
