Thermal Blanket, Microwave Sounding Unit
This is a flight spare of a thermal blanket for a Microwave Sounding Unit (MSU), an instrument flown on Tiros meteorological satellites beginning with Tiros-N in 1978.
The MSU's purpose was to measure the temperature profile of the Earth's atmosphere from the planet's surface to a height of 20 km. MSU, manufactured at the Jet Propulsion Laboratory, and other instruments on the Tiros series of satellites are part of on-going program to gather a range of data on the characteristics of and changes to the Earth's atmosphere over a period of years. MSU data on atmospheric temperatures has contributed to scientific discussions of whether the Earth is experiencing a warming trend.
The last MSU flown in space, launched on the NOAA-14 satellite (part of the Tiros program) in 1994, is still gathering data as of 2007.
The National Oceanic and Atmospheric Administration transferred this artifact to the Museum in 2004.
