November 15, 2008 , India 's first unmanned lunar spacecraft in lunar orbit last night , released a Juan flag of India the moon impact probe , successfully striking the lunar surface , making India the United States, Russia And the European Union , the flag appears in the fourth month of the States .
According to " News Agency "report , While this the future of India to verify the technology required for the moon surface, the moon impact probe , weight 35 kg , size, size is 375 mm long, 375 mm wide, 470 Mm high .
India's national space research authorities , " Indian Space Research Organization , " officials said , the moon impact probe to leave the Indian ships first unmanned lunar exploration , " the spacecraft at the Moon " , about 25 minutes , successfully hit the lunar surface , accurate impact time Is 20:31 ( GMT 23:01 ) .
India 's space officials as " a perfect mission , " the moon impact probe , impact the lunar surface in about 25 minutes before the close process, installed in the detector 's radar altimeter , camera system and the mass spectrometer continues to operate continuously Shooting the moon , measure and send back data. Officials said the choice of these data will help India in the future location of the spacecraft landing on the moon .
India is on October 22, 2008 , by the self-made " Polar satellite launch vehicle " carrying " the spacecraft at the Moon " off , started India 's first ever trip to the moon .
Total weight 1.38 tons of " on the 1st lunar spacecraft " , is India 's first unmanned moon mission spacecraft , the next two years around the moon, survey the entire lunar surface , using high-resolution remote sensing equipment , analysis of the lunar surface Composition , drawing three-dimensional electronic map , and release during the lunar impact probe , for India 2020 years ago, manned spacecraft to the moon intended to prepare .
" on the 1st lunar spacecraft " probes , were involved in assisting European countries , loaded with 11 exploration equipment , including five self-developed by India , including the impact detectors, and four of the European Union, the United States is also the detector Installation of a miniature synthetic aperture radar two instruments designed to measure whether the lunar surface with water, ice and mineral resources .
India Space Agency Chairman G Madhavan Nair of India's technical extreme self-confidence : "I think no other country can for the first time when the moon can be so precise .
BEIJING, March 1 call at 4:13:10 p.m. on March 1st , Chang'e One satellite in the Beijing Aerospace Control Center, under the precise control of scientific and technical personnel , accurate down to the lunar longitude 52.36 degrees , 1.50 degrees south latitude scheduled Impact point , to achieve the desired goal for the Chinese lunar exploration project a painting to a successful conclusion .
According to the National Defense Science and Technology Industry Council news , lunar probe satellite on October 24, 2007 at the Xichang Satellite Launch Center , Nov. 7 to enter the ring on the work of 200 km orbit , to October 2008 has been successfully running an in-orbit Years after the completion of scheduled tasks in good detection . To take full advantage of Chang'e satellite in orbit valuable resources for follow-up mission to carry out the experiment, the accumulated data and experience , the lunar exploration project leading group decided in accordance with the " track from high to low , the risk from small to large "principle, application of Chang Satellite launched a satellite platform at the technical test and satellite orbital transfer capability , orbit determination capability of more than 10 verification tests . Verification test from November 8, 2008 began on schedule the smooth implementation of the satellite orbit by a 200 km circular orbit down to 100 km circular orbit , then dropped to 100 km distant point on , in recent months, point 15 km elliptical orbit , up again Back to the 100 km circular orbit at the same time , the technology of satellite part of the system test and reliability test , made a number of valuable technical test data for the second phase of the lunar exploration project has accumulated valuable technical and engineering experience .
Exploration of the second phase will achieve a soft landing , technology span , as in process control and orbit determination sangrakwol accumulated experience , to reduce the risk of follow-up project , decided to end life in the lunar probe satellite , control, satellite impactors .
To ensure the Chang'e I satellite "controlled crash on " lunar probe mission flight control group selection in Qingdao and the Kashi two monitoring stations able to carry out monitoring and control of the time period for sangrakwol control . This afternoon, 15:36 , Chang'e One satellite began to slow down , 37 minutes later , at 16:13:10 successfully landed on the moon -rich sea area . Satellite on collision course , CCD cameras, real time back to a clear image .
It is understood that Chang'e satellite in orbit for one year , a total return 1.37TB effective scientific survey data , access to the full moon maps, the distribution of chemical elements on the table part of a batch of scientific research results , successfully achieving project goals and Scientific objectives, the follow-up project for the Chinese lunar exploration and deep space exploration has laid a solid foundation .
Analysis:
India's lunar exploration satellite " successfully hit the lunar surface that is more than a month . "
Lunar probe satellite on October 24, 2007 launch , on Nov. 7 to enter the ring on the work of 200 km orbit , from October 2008 has been successfully operating in orbit for one year , only hit the moon . Chinese scientists too lazy to it!
Haha . Review once again :
Lunar probe satellite on October 24, 2007 at the Xichang Satellite Launch Center , November 7 200 km of the ring into the work on track , to October 2008 has been successfully operating in orbit for one year after the completion of scheduled tasks state probe Good . To take full advantage of lunar probe satellite in orbit valuable resources for follow-up mission to carry out the experiment, the accumulated data and experience , the lunar exploration project leading group decided in accordance with the " track from high to low , the risk from small to large "principle, application of Chang Satellite launched a satellite platform at the technical test and satellite orbital transfer capability , orbit determination capability of more than 10 verification tests . Verification test from November 8, 2008 began on schedule the smooth implementation of the satellite orbit by a 200 km circular orbit down to 100 km circular orbit , then dropped to 100 km distant point on , in recent months, point 15 km elliptical orbit , up again Back to the 100 km circular orbit at the same time , the technology of satellite part of the system test and reliability test , made a number of valuable technical test data for the second phase of the lunar exploration project has accumulated valuable technical and engineering experience .
Exploration of the second phase will achieve a soft landing , technology span , as in process control and orbit determination sangrakwol accumulated experience , to reduce the risk of follow-up project , decided to end the life of Chang'e satellite control on satellite hit .
Who hit the satellite more valuable? I like to do Chinese people !
