1. Prepare materials: starry sky pictures, moon pictures and "Chang'e Satellite" pictures. (It is best to use image processing software to remove the background of moon images and satellite images.)

2. Insert material: Run PowerPoint 2003, create a new blank slide, and execute the "Format-Background" command to insert the "Starry Sky Chart" as the background. Then execute the "Insert - Picture - From File" command to insert the "Moon Picture" and "Satellite Picture" in sequence, and adjust the size, proportion and position.
3. Create animation effects: Select "Satellite Image" with the left mouse button and execute the "Slide Show - Custom Animation" command, expand the "Custom Animation" task pane, click the drop-down button to the right of "Add Animation", select "Action Path - Other Action Paths" in the drop-down list, and select the "Circular Expand" command in the "Basic" type. Then use the mouse to adjust the position and size of the path through the six control points. Stretch it into an oval shape and adjust it to the appropriate position.
4. Set animation: Double-click the "Circular Expansion Animation" just created in the "Custom Animation" pane with the left mouse button to open the "Circular Expansion" settings panel, click "Timing" with the left mouse button, and select "Before" for the "Start" type under it, "Slow (3 seconds)" for the speed, and "Only until the end of the slide" for repetition. In this way, "Chang'e" can automatically fly around the moon over and over again.

5. Draw the running track line: Use the "Ellipse" tool in "AutoShape" to draw an elliptical shape, adjust its size and position so that it coincides with the "Circular Expansion Animation" path, then set its "Fill Color" to "No Fill Color", and set your favorite color and thickness for the line. Finally, right-click the "ellipse graphic" to execute the "Stacking Order-Move Down One Level" command to let the "satellite" orbit around it.
6. Surround processing: Copy and paste the "Moon Picture" so that it completely overlaps the "Moon Picture" just inserted. Right-click the "Moon Map" just pasted and execute the "Show 'Picture' Toolbar" command, open the "Picture" toolbar, select the "Crop" command, and crop the "Moon Map" just copied from bottom to top to a suitable size, so that the "satellite" has the effect of orbiting the back of the moon.
