Events: China's first Mars probe launch during the year to 10 months to reach Mars

Core tips
Recently, the reporter learned from parties concerned: the Sino-Russian joint exploration of Mars will be held before the end of the year. By then, the country responsible for the development of the "firefly One" Mars probe (The picture shows the "Firefly One" satellite model. This reporter Yu Jianbin photo), will be developed with Russia, "Forbes - Soil" Mars probe together with the Russian "Zenith" carrier rocket launch to Mars. Currently, the "Firefly One" are like stars have been shipped en, will carry out a series of related tests. Since the launch window for up to 1 month, "Firefly One" will _select_ the most appropriate time, from Kazakhstan's Baikonur Space Launch Centre.
Weighing about 110 kilograms, take 10 months to reach Mars
According to reports, China-Russia joint Mars exploration program established in 2007, the two sides will jointly on Mars and its satellite Phobos were detected. Under the agreement, the Chinese side is responsible for development of the "Firefly One" Mars probe will orbit around Mars on the Mars space environment and detect large-scale topography.
"'Firefly One' although was a star of the limited capacity of small satellite, but it focused scientific goals, the important thing to do, 'cost' is high." Chinese Academy of Space Science and Applied Research Center, "Firefly One" Wu Chi engineering chief scientist said.
"Firefly One," the weight of only 110 kilograms, is a small satellite. It has launched a two-way balance of solar panels, used to obtain energy. And the earth satellite is different from the orbit of Mars around the sun than the Earth low energy density, so "firefly One," the solar panels look bigger than the Earth's satellite.
From Earth to Mars, "firefly One" Star Trek will be up to 10 months, eventually will enter a spin around the large elliptical orbit of Mars, which is far away from the fire point of about 80,000 kilometers of Mars, near the fire some distance on Mars 800 km. "Firefly One" will be in the orbit of a planet, about 120 laps.
Targeting areas of the space environment of Mars probe's first
Mars upper atmosphere and ionosphere
According to Wu Ji, the "Firefly One," is mainly carried out on the Martian upper atmosphere and space environment exploration, including the Martian magnetic field, ionosphere and particle distribution and its variation, Mars atmospheric escape rate of ions, Mars terrain landscape and dust storms, and the equatorial region of Mars gravity field of detection.
So far, most human Mars concern is whether life exists on Mars, the international exploration program is mainly directed against the existence of water on Mars, or focus on detecting signs of life.
"Firefly One," the implementation of China's first Mars Exploration Program, in a large oval around the equator of Mars on the Mars orbit space environment to carry out exploration on the Martian upper atmosphere and ionosphere, and atmosphere with the solar wind interaction region the implementation of a comprehensive detection, In the first time in human history.
The depth of Russia's largest space project cooperation
China's own Mars exploration plans have been waiting for project
Of China and Russia, the China-Russia joint Mars exploration plans can be described as the depth of current cooperation between the two countries the largest space project. According to reports, Russian Academy of Sciences in 2004 decided to implement the detection of Phobos. In order to expand the results of this pilot scheme, the Russian space agency decided to let out some of the resources used to carry foreign detectors. In the framework of Sino-Russian cooperation, the Chinese scientific community access to this opportunity.
