Did you know?

Some NASA facts

Four days after it was launched, the Deep Space 1 spacecraft was about 1,000,000 kilometers (about 600,000 miles) from Earth. To fly that far in a jet, you would have to fly for 6 weeks without stopping!


To communicate with distant spacecraft, NASA's Deep Space Network uses antenna with a diameter of up to 70 meters (230 feet). That is almost as big as a football field.


It's a small world. More than 1,000 Earths would fit into Jupiter's vast sphere.


Saturn's beautiful rings are not solid. They are made up of particles of ice, dust and rock -- some as tiny as grains of sand, some much larger than skyscrapers.
