Back in 1969,it was the Apollo 11 crew who flew to the moon in a spaceship.When U.S.astronauts Neil Armstrong and Edwin “Buzz”Aldrin stepped foot on the moon,they were the first.Meanwhile,their fellow astronaut Michael Coilins circled the moon in their spaceship,named Columbia. When Armstrong and Aldrin were done with their walk,they returned to the command module,and back to Earth.That part of the spaceship is on view at the Smithsonian’s Air and Space Museum in Washington,D.C.But,if you cannot get to Washington,soon you will be able to see Columbia on your computer or your smartphone. Digital scientists are scanning the inside of the spaceship.They are creating an online model,in three dimensions,or“3 D”.By looking at these photographs,you will be able to see outer space,the way the astronauts did.It will be like sitting in their seats. Want your very own Columbia spaceship? You will be able to print a 3D copy of Columb ia.Experts say anyone can make a life-sized model.But they expect most people to make smaller models of the 320×400 cm(11’X 13’)command module. Scientists are using special 3D technology to scan the inside.They use cameras on lo ng arms to take the photographs.The thousands of photographs taken will be combined with 50 laser scans. What would it be like to sit inside Columbia and take a look around? All the images will be loaded into software that allows you to look around the module on a computer screen.The user will be able to see the Columbia both inside and out.The Smithsonian says that the 3D technology gives the user ways to see things they cannot see at the museum.And it will give information that even the museum curators(馆长)have not seen before. “With the Command Module,no one has been inside since it came into the collection,”says Adam Metallo.Smithsonian 3D imaging specialist.“Now the information we capture can give anyone in the world a view of what it looks like inside this incredible piece of history.”
