The Aeronomy of Ice in the Mesosphere (AIM) satellite mission is exploring Polar Mesospheric Clouds (PMCs), also called noctilucent clouds, to find out why they form and why they are changing.
The AIM mission has been extended by NASA through the end of FY12. During this time the instruments will monitor noctilucent clouds to better understand their variability and possible connection to climate change. Individual instrument data collection status, as well as spacecraft and instrument health, will be monitored throughout the life of the mission and reported periodically on this earth
Hope this helps :)

What are 2 fact abouut mesosphere?
The mesosphere is the third layer of atmosphere away from the surface of the Earth, which comes after Troposphere and Stratosphere. In the mesosphere temperature decreases with increasing height. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth with temperatures below 130 K. The exact upper and lower boundaries of the mesosphere vary with latitude and with season, but the lower boundary of the mesosphere is usually located at heights of about 50 km above the Earth's surface and the mesopause is usually at heights near 100 km, except at middle and high latitudes in summer where it descends to heights of about 85 km.
What are the layers of the atmosphere and what are their approximate heights?
The layers of the atmosphere, from lowest to highest, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Their approximate heights are: troposphere (up to 12 km), stratosphere (12-50 km), mesosphere (50-85 km), thermosphere (85-600 km), and exosphere (600+ km).
Can satellites and airplanes fly in the mesosphere?
No, there is too much atmospheric drag at these heights for a satellite to maintain an orbit, but it is too high for airplanes which have 'air breathing' engines. Some high altitude planes such as the SR-71 Blackbird and U2 can fly up to 25km, but not as high as 50km which is the lower boundary for the Mesosphere. Some experimental rocket planes such as the X-15 have been able reach these heights.
Why mesosphere have constant temperature?
The mesosphere, which lies between the stratosphere and the thermosphere, experiences a decrease in temperature with increasing altitude. This is primarily due to the diminishing density of air and the limited absorption of solar radiation at these heights. Unlike the stratosphere, where ozone absorbs UV radiation and warms the air, the mesosphere lacks significant heat sources, resulting in cooler temperatures. Therefore, temperature in the mesosphere is generally constant and decreases with altitude, reaching its coldest point at the mesopause.
What is the density of the mesophere?
The mesosphere is the third layer of Earth's atmosphere and is characterized by its very low density. The density of the mesosphere ranges from about 1 x 10^-10 kg/m^3 to 1 x 10^-13 kg/m^3 at different heights within the layer.
Where is the mesosphere?
The mesosphere is in space it is the 3rd atmosphere.
What the synonyms for mesosphere?

Does mesosphere have ozone?
No. The mesosphere doesn't have ozone.
What is a sentence with heat mesosphere?
The heat that mesosphere generates is immense. Mesosphere is a layer in atmospheric region.
What is the mesosphere between the mesosphere and the thermosphere called?

How many syllables are in the word mesosphere?

Is the mesosphere in the middle of the atmosphere?
The mesosphere is located in the middle of the atmosphere
