Web1.- Background a) Background in Astronautics Sir Isaac Newton discovered the concept of what is commonly named nowadays “orbiting”, long ago. This famous XVII-XVIII century scientist described what he named “everlasting free fall”, the orbiting of today. He was studying the firing of a cannon in horizontal position, considering no atmospheric effects … To summarize, the lowest possible sustained circular orbits are at of order 125 km altitude, but elliptical orbits with perigees at 100 km can survive for long periods. In contrast, Earth satellites with perigees below 80 km are highly unlikely to complete their next orbit.
