    Look at it this way. How far away is the moon? (about 234,000 miles) 
    It takes 28 days to make one orbit. How far are the geo birds? They 
    are 23,300 miles away and they stay in exactly the same spot over the 
    earth at the equator.
    That said, it is NOT the slowing down that makes it go up and it 
    (ISS) cannot get itself up higher, it must be "boosted" to a higher 
    Go to:   and click on "FUN PAGE"  a pop-up will come up 
    with selections. Then click on "HOW TO ORBIT" button. If you have 
    microsoft word, download the file and see the answer. There you will 
    also find a diagram explaining the whole process. I did this a couple 
    of years ago as a project.
    Bottom line: NOTHING technically "orbits" the earth. All objects 
    orbit the sun. These objects "going around" the earth are actually 
    "zig-zagging" around the earth. Look at the diagram and you'll see 
    what I mean.
