A geosynchronous orbit (GSO) is an Earth orbit where the orbital period matches the Earth’s rotation. There is a special case of a GSO called a geostationary orbit where a circular GSO has no inclination to the Earth’s equatorial plane and is directly over the equator at an altitude of about twenty three thousand miles.
I have blogged in the past about the fact that space is not a friendly place. It takes a toll on human beings who spend a lot of time there. Calcium leaches out of the bones, muscles lose mass, there is damage to the visual system, and dangerous radiation is common and could lead to cancers. Today, I am going to go into more detail on the damage to astronauts’ eyes.
I have blogged before about all the debris orbiting the Earth left over from space launches. It is estimated that there are more than one hundred million pieces of debris that are less than 1 centimeter in size. They are too small to track with radar, but some are still big enough to cause serious damage to a space craft because they are traveling so fast.
