From LUCA's Space cell for 2nd and 3rd Grade. Placeholder name “Alex”.
Alex and his friend Jan were on a space ship. The crew was set to land on the moon. "Hold tight!" said Alex. The ship went down fast to the moon. They landed with a soft bump. Jan got out in her space suit. She walked on the dusty rock. "This is huge!" she said. Alex took a flag and put it in the moon rock. They stood next to the flag and waved. The moon trip was the best one ever.
