Last weekend,after pay a visit to the city of New York,I visited the Smithsonian Institutions National Air and Space Museum,where lies in Washington,D.C.

The museum,which covers a area of 18,000 square meters,is made of 24 exhibition halls.All kinds of planes, rockets,missiles and spaceship of great importance and variously old instruments that famous pilots and astronauts used are on display.In addition,I see copies of some satellites and aircraft.More interestingly,I tried operating on some aircraft by myself.During the visit,I took lots of pictures as well.

This brief visit helped myself learn much about the history of human's space exploration.It made me more interesting in science and technology.
