BEIJING, Aug. 3 (Xinhua) Chinese scientists to use “Chang E” satellite lunar year to detect the flight of scientific data, has received a number of results. The “Chang-e II” will be launched by 2011.
Central Television reported, lunar exploration project leading group of major projects Fellow senior adviser Ouyang said, “Chang-e One” satellite has four major science mission well done, get a large number of valuable scientific results. In the “Chang-e One” for scientific research, there are many Chinese scientists conducted the first in the world.
returned Chinese scientists using satellite image data, map out a full month figure, which is the world’s most comprehensive, highest accuracy, a monthly chart. According to Ouyang introduced, this figure is only a month plan, this year, Chinese scientists will also provide a full moon to the world three-dimensional image map.
One of the probe data according to Chang-e, scientists also find out the moon on the eight kinds of initial distribution of the elements. In addition, the use of Chang-e One load on the satellite microwave remote sensing devices, the world’s first Chinese scientists also get the Moon’s surface brightness temperature distribution, which helps to further calculate the thickness of lunar soil and to estimate the monthly in helium-3 content of soil.
more than a year of flight around the moon, Chang E One recorded a lot of space weather processes, which scientists study the space environment to provide a large number of first-hand information.
According to another report, but as a “Chang-e One” sister Star – “Chang-e II” is kind of the satellite are also in the development phase, is expected to launch in 2011.
“Chang-e II” was originally “Chang-e One” backup satellite, so two stars in the shape and weight, and not much difference. But it will be Chang-e lunar orbit 200 km altitude at the time reduced to 100 km, so that it can see the moon more clearly. To this end, researchers installed a resolution for its 10-meter CCD camera, which at 120 m resolution than the Chang-e camera looks clearer and more detailed.
the same time, Chang E II will continue Chang-e One of the scientific objectives, the distribution of elements on the lunar surface, the thickness of lunar soil, earth-moon space environment to do further scientific exploration.
In addition, according to plan, China’s “Chang-e III” satellite will carry the rover landed on the lunar surface, so the “Chang-e II” is an important task for “Chang-e III” Pathfinder , after the completion of lunar exploration, it will take a “soft landing” approach to lunar landing.
It is understood that the previous two satellites completely different, “Chang-e III” has also been completed design is expected before the end of this year into the initial research stage, and in about 2012 or 2013 to achieve first “moon” soft landing. The fastest to 2018, China will launch a lunar sample return device, a soft landing on the lunar surface specific area, then the lunar samples back to Earth.
of China’s first lunar probe “Chang-e One” was successfully launched in October 2007, and March 1 this year, “Chang-e One” accurate down to the intended point of impact the Moon.
