Artificial satellites are easily observed most nights when the weather is fine. The website called "Heavens Above" at www.heavens-above.com will help locate these satellites flying over one's location. It also includes how bright they will appear. The direction of travel of each satellite in the night sky also indicates the type of satellite. For example, astronomical and scientific satellites, such as the Hubble Space Telescope, move west to east. The International Space Station and the space shuttle move southwest-to-northeast or northwest-to-southeast. A north-to-south or south-to-north moving satellite is usually a meteorological or Earth environmental satellite such as Envisat. Finally if a satellite follows a retrograde (southeast-to-northwest) path, it is most likely a spy satellite. This article presents a homework idea that will help students determine: (1) the orbital period, altitude and speed of four naked eye satellites; (2) if various landmarks are visible from the Moon, Space Station or the space shuttle; and (3) the distance to the horizon from the Space Station and the field of view.
