According
to Chinese news agency Xinhua, China successfully launched its first lunar
probe on Wednesday.
The Chang'e
I blasted off at about 6:05 pm on a Long March 3A carrier rocket from the No. 3
launching tower in the Xichang Satellite Launch Center in Southwest China's Sichuan Province.
The mission
is named after a Chinese goddess who, in a popular fairy tale, lives on the
Moon.
Chang'e 1
is based on China's Dongfanghong 3 telecommunication satellite platform and
reportedly carries a 280-pound (127-kilogram) payload of science instruments
for its planned one-year mission.
The
spacecraft carries a total of eight primary instruments to photograph and map
the lunar surface, probe its depth, study the regolith's chemical composition,
and analyze the space environment around the Moon.
According
to the mission description, Change'1 carries two basic imagers.
A CCD
stereo camera will produce three-dimensional images of the lunar surface by
compiling three separate, two-dimensional views of each target area. Meanwhile,
the probe's interferometer spectrometer imager is expected to overlay optical
measurements with spectra to depict the regional distribution of resources and
materials.
Chang'e 1
will also carry a laser altimeter to take precise elevation measurements of the
lunar surface, as well as gamma/X-ray spectrometers to hunt out and measure the
amount of up to 14 elements – among them iron, potassium, uranium and titanium.
A microwave
detector will bounce signals down to the Moon's surface, operating on four
different frequencies to determine the lunar regolith's depth, while a
high-energy solar particle detector and low-energy ion instrument – Chang'e 1's
space environment monitor system – measures the solar wind environment, according
to the CNSA mission description.
A payload
data management system rounds out Chang'e 1's instrument package. Also riding
to the Moon aboard the lunar probe are some 30 songs, among them Chinese folk
songs and "The East is Red" – China's national anthem – Xinhua reported in
November.
The launch
is the first step into the country's three-stage moon exploration plan.
According to Xinhua Chinese
space experts, technicians and other work staff, were joined by experts from Japan, Germany and other countries to observer the launch process.
The
circumlunar satellite is expected to enter the Earth-moon transfer orbit on
October 31 and arrive in the moon's orbit on November 5.
The
satellite will relay the first pictures of the moon in late November and will
then continue scientific exploration for a year.
