ချန်အဲ ၁ လကမ္ဘာလေ့လာရေးယာဉ်

ချန်အဲခရီးစဉ်တွင် အဓိကရည်မှန်းချက် ၄ ခုရှိသည်။ [7][11]

1. လမျက်နှာပြင် ဘူမိတည်ဆောက်ပုံနှင့်မြေပြင်အနေအထားတို့အား သုံးဖက်မြင်ပုံများရယူပြီး အနာဂတ်လပေါ်ငြိမ့်ညောင်းစွာဆင်းသက်ရန်အတွက် မှီငြမ်းမှုပြုခြင်း။ ချန်အဲ ၁ ၏ လပတ်လမ်းThe orbit of Chang'e 1 around the Moon was designed to provide complete coverage, including areas near the north and south poles not covered by previous missions.
2. Analysing and mapping the abundance and distribution of various chemical elements on the lunar surface as part of an evaluation of potentially useful resources on the Moon. China hopes to extend the number of elements studied to 14 (potassium (K), thorium (Th), uranium (U), oxygen (O), silicon (Si), magnesium (Mg), aluminium (Al), calcium (Ca), tellurium (Te), titanium (Ti), sodium (Na), manganese (Mn), chromium (Cr), and lanthanum (La)),[12] compared with the 10 elements (K, U, Th, Fe (iron), Ti, O, Si, Al, Mg, and Ca)[13] previously probed by NASA's Lunar Prospector.
3. Probing the features of the lunar soil and assessing its depth, as well as the amount of helium-3 (³He) present.[12]
4. Probing the space environment between 40,000 km and 400,000 km from the Earth, recording data on the solar wind and studying the impact of solar activity on the Earth and the Moon.

In addition, the lunar probe engineering system, composed of five major systems – the satellite system, the launch vehicle system, the launch site system, the monitoring and control system and the ground application system – accomplished five goals:

• Researching, developing and launching China's first lunar probe
• Mastering the basic technology of placing satellites in lunar orbit
• Conducting China's first scientific exploration of the Moon
• Initially forming a lunar probe space engineering systemတမ်းပလိတ်:Clarify me
• Accumulating experience for the later phases of China's lunar exploration program

According to the schedule, detailed design of the first program milestone was completed by September 2004. Research and development of a prototype probe and relevant testing of the probe were finished before the end of 2005. Design, manufacture, general assembly, test and ground experiments of the lunar orbiter were finished before December 2006.

Originally scheduled for April 2007, the launch was postponed until October as this was "a better time for sending a satellite into the Moon's orbit".[14] Chang'e 1 was launched by a Long March 3A rocket at 10:05 GMT on October 24, 2007 from Xichang Satellite Launch Center in Sichuan Province.

After liftoff, Chang'e 1 made three orbits around the Earth, a burn at perigee extending the orbit's apogee further each time, until a final translunar injection burn placed it on course for the Moon on October 31, 2007. Another burn placed it in a polar orbit around the Moon, with burns at the perilune of the first three orbits decreasing the apolune until it entered a final circular orbit. Lunar orbit insertion was achieved on the November 5, 2007. To mark this occasion, the probe transmitted 30 classical Chinese songs and musical pieces, including "My Motherland", "The Song of the Yangtze River", and "High Mountains and Flowing Water".

The probe was remotely controlled from stations at Qingdao and Kashgar, as the first use of the Chinese Deep Space Network. The ESA Maspalomas Tracking Station was also used to transmit signals to and from the probe.

The first pictures of the Moon were relayed on November 26, 2007. The probe was designed to orbit the Moon for one year,[12] but operations were later extended, and it remained in lunar orbit until March 1, 2009.

၂၀၀၉ခုနှစ်၊ မတ်လ ၁ရက်နေ့တွင် ချန်အဲ ၁ သည် လမျက်နှာပြင်သို့ဝင်တိုက်ပြီး ခရီးစဉ်ပြီးဆုံးခဲ့သည်။ According to the State Administration of Science, Technology and Industry for National Defense (China), this was a planned and controlled impact.[15] Impact point was 1.50°S 52.36°E / -1.50; 52.36.[16][17][18] During its orbital mission the probe transmitted 1,400 gigabits or 175 gigabytes (GB) of data.
