Sarah stopped in front of a large, spider-like machine with four legs. It had a gold-colored base and several small windows around its sides.
"This is a model of the lunar lander," Alex explained. "These special spacecraft were designed to land astronauts safely on the moon's surface. The legs help it stand steady on the rocky moon surface."
"But why does it look so different from regular spacecraft?" asked Sarah.
"That's because it only needs to work in space and on the moon," Alex replied. "It doesn't need to be streamlined like rockets that have to fly through Earth's atmosphere. The gold foil helps protect it from extreme temperatures in space!"
