问题 What is the purpose of launching the AIM spacecraft?
The AIM spacecraft is scheduled for launch next Wednesday from Vandenberg Air Force Base in California. AIM stands for Aeronomy of Ice in the Mesosphere.(27)The craft will study mysterious ice clouds above Earth’s polar region—clouds that can be seen from Earth with the naked eye in the night sky. Little is known about these night-shining clouds, or the distant mesosphere, 80 kilometers above Earth’s surface where they form, except that they are changing. Some scientists believe it may be the result of human induced climate changes.
选项 A、To study the climate changes above Earth’s polar region.
B、To analyze the ice clouds within Earth’s polar region.
C、To analyze the climate changes within Earth’s polar region.
