He put his foot on the moon and said, "This is one small step for a man." Dr. Thorne came down next, and then Mark Chen followed. All three of them stood on the moon. The ground was grey and dusty, and the sky was black, not blue like on Earth. They could see Earth far away in the sky. It looked small and beautiful. The astronauts felt very happy and started their work.
First, they took out the USA flag. Commander Evans held the flag pole and pushed it into the ground. The flag stood up straight. It was a proud moment. Then, Dr. Thorne said, "Let us start our work." Everyone agreed. They had many things to do. Their first job was to collect soil. Dr. Thorne took out a small shovel, bent down, and picked up some grey dust. He put the dust into a white bag and wrote on the bag to mark it. Commander Evans collected rocks. He found small stones and big stones and put them into special containers. Mark Chen set up a small camera that sent pictures to Earth. He also placed a machine on the ground to measure moonquakes. They worked slowly and carefully because the space suits were heavy and moving was not easy. But they were happy to be on the moon. They jumped a little because the gravity was low, and they could jump high very easily. It was fun. People on Earth watched them through the camera with big smiles.
The astronauts kept working for a long time. Dr. Thorne collected many soil samples from different places. Commander Evans walked further to find unique rocks. Mark Chen set up more experiments and took photos of everything. They were doing important work. Suddenly, something changed. Dr. Thorne looked up and saw something in the black sky. It was a rock moving very fast. It was a meteor, and it was coming towards the moon. Dr. Thorne shouted, "Look!" Commander Evans and Mark Chen looked up too. They all saw the meteor. It was bright and fast. The meteor hit the ground far away. There was no sound because there is no air on the moon, but they saw dust rise up in a big cloud. It was a big hit. The ground shook a little, and all three astronauts felt the shake.
