This logo is used for the Landsat program. LCDM means Landsat Data Continuing Mission.
Satellite images have been around since 1946. Landsat 7 launched into orbit in 1999 and is still there. The satellite images I have here are from her.
This is a NASA satellite image of Belcher Islands in Southeast Hudson Bay, Canada.
Landsat 8 is like Landsat 7 with some bells and whistles added.
I am going to do a basic post on this.
Part of this mission, which is for 3 years, is to measure the temperature of the land on Earth.
This is a drawing of finding the hottest spots on Earth, by NASA.
I have to say that I got highly confused about which part was which. This is normal to me.
TIR will be used to record surface temperatures. One thing it will be doing is sensing the different temperatures in the states in the US that have large crops fields. This has to do with the amount of irrigation used for the crops. There is a lot of irrigation for crops and the temperature of the irrigated land is different that the dry land. It will also help with sensing drought areas.
This is a picture of pivot irrigation from US Department of Agriculture.
Corn field in Ohio. Ohio is a state in the US. By, graylight, Wikipedia Commons.Another major part is called Operational Land Images, OLI. This will be able to take pictures of Cirrus clouds and coastlines as well as land images.

This is a parts drawing of Landsat 8. The rectangular thing on the right is the solar array that will capture sunlight to power the spacecraft.
This last picture is a drawing of Landsat 8 in orbit around the Earth.
