Satellite Savvy

Did you know...?

Satellites can find a whale's food. They can track the movement of large schools of plankton, which are tiny shrimp. These are a primary source of food for many whales.

Satellites can tell if a storm is coming. They can see shifts in ocean and air currents which may bring about storms. For example, weather satellites regularly "watch" for hurricanes as they develop off the coast of Africa. The satellites then follow the hurricanes as they move to see if they will threaten the United States.

Satellites can tell us about fish. They can tell us where fish are likely to be, based on food preferences and water temperature. This information helps fisheries biologists understand where fish go at different times of year. It also helps them keep track of fish populations, to see which fish species are doing well and which need help. The biologists can then recommend how many fish fishermen can catch of each species.

Satellites can help us call a friend in Japan. Telephone signals are bounced off satellites in space to help us call friends and family on the other side of the world.

Satellites can take a picture of your house. Satellite technology has become so refined that a satellite high up in space can be instructed, via computer, to zero in on not only your town but your street and even your house.
