Some ideas for my poster compitition?

You could make it interesting by making it 3d. Cut styrofoam in half(each according to the size of the planet) and painting them the way they appear. Have a man standing on the moon. with a banner with the names of astronauts that have stood or been on the moon's surface. Flags on any planets that we have gotten actual photographs of from one of the exploration flights. Be sure to give the information about them. When and where we got the photos. Have a small model or picture of a space satellite floating among the planets. On the bottom you could have someone gazing up at the stars. Good luck!
