Explanation: What's happening between those mountains? A rocket is being
launched to space [4] . Specifically, a Long March 3B [5]  Carrier Rocket was
launched from Xichang Satellite Launch Center [6]  in Sichuan Province [7]  in
China [8] about two week ago. The rocket [9]  lifted two navigation [10]
satellites [11]  to about 2,000 kilometers above [12]  the Earth's surface,
well above the orbit of the International Space Station [13] , but well below
the orbit of geostationary [14]  satellites. China's Chang'e 3 mission [15]
that landed the robotic Yutu rover [16]  on the Moon was launched from Xichang
in 2013. The featured image was taken about 10 kilometers from the launch site
and is actually a composite of nine exposures, including a separate background
image.
