Charng-er no.2 satellite simulation diagram.
By April 1, already safe operation charng-er no.2 180 days, which reached its design life half a year. According to introducing, at present satellite fuel remaining still enough, engineering all concerned parties are study demonstrates, given the moon mission, for 2 more lunar project completed phase foundation subsequent tasks.
Safe operation 180 days, reach half a year now, satellite system design life normal stable state
According to the national defense science and technology GongYeJu news, at present our country second lunar satellite charng-er no.2 satellite system normal stable, has already been fully realized established project goals, gained a lot of important scientific achievement.
Charng-er no.2 satellite last October 1, launched in recent months, after earth-half braking, lunar flight, fall rail control, litre rail control etc, on the ring key link to orbit on work. Since then, satellite respectively in 100 * 100 kilometers of circular orbit and 100 x 15 kilometers of the elliptical orbit on high resolution imaging and ring detection.
Over the last six months, satellite systems, measurement and control system and ground application system carefully organized the various detection work, closely monitor satellite working state.
At present, the goddess of the moon orbit satellite no.2 in good condition, has obtained seven metres complete resolution of the surface of the moon a three-dimensional image data, is scheduled to launch four science continued of target detection activities.
Satellite fuel remaining still enough, "final destination," may try to expand the detection of experiment
Previously, after finishing the goddess of the moon landing on no.3 fall primary task of local area area rainbow bay high resolution imaging, charng-er no.2 satellite last October 29 began to rise rail back to 100 kilometers long period running full moon orbit ring, and from November 2nd, flight control center by Beijing aerospace for implementation the long-term management charng-er no.2 satellite missions, relying on the whole lunar surface mainly high resolution imaging many scientific exploration test on long-term ring.
In the long-term management, year need to continue CeKongZhan unified dispatching every relevant space, has the choice, give priority to tracking measurement satellite, daily to keep the satellite platform and rail state surveillance analysis.
In early last year to rainbow bay moon no.2 finish after the main task of the high-precision imaging, because there are many fuel left, then researchers expect their actual life will design life long than to the goddess, which makes the public after final mission no.2 produced end-result of great interest: whether, or fly into the moon on further deep space, or to try to return. This satellite reached half year life to be sure.
According to the lunar probing concerns chief introduction, April 1, 2 reach half moon, satellite system after the design life in good condition. Satellite fuel remaining still enough, will exceed the original design of the half year life. With current projects all concerned parties are study demonstrates, given the moon mission, and 2 more maximum exert its function, for the subsequent deep-space exploration lay the foundation. Fyi, in complete life period after each task ii will conduct further, the goddess of detection test, expanding to complete the lunar project phase ii follow-up task to lay solid foundation.
No.3 2013 moon before on the ongoing falls, the product the development there
At present, China's lunar exploration engineering to none detection is given priority to, divided into "round" and "falls" and "back" three stages.
"Around", namely lunar phase of the project, 2004 to 2007 implementation, task is to launch of a moon orbiter, implement lunar exploration. October 24, 2007, charng-er's no.1 satellite launch. In task completion and overterm service 2009 127 days later, on March 1, controlled in lunar surface successfully hit sea area rich. Charng-er's no.1 won 1.37 TB scientific detection data.
"Fall", namely lunar in 2008, the second phase of the project implementation until 2014, realize the lunar surface to a soft landing detection and lunar surface survey, divided into charng-er no.2 patrols, no.3 and no.4 task moon goddess. Among them, the goddess a soft landing for the lunar surface no.2 bear some key technology mission verified, and the subsequent primary landing zone implementation accurate detection, still take lunar exploration mode. The goddess is planning no.3 task before and after a soft landing on the moon in 2013 and automatic patrol survey. The goddess of the moon 3 to 4 backup stars.
"Back", namely, lunar third-phase project task is to realize the lunar surface sampling returns. Recently, the state council has approved the implementation scheme of lunar third-phase project, the third-phase project research work has been comprehensively launched. |
