The kids observe the full Moon at night and wonder why it seems to have a "face." They research why the light and dark splotches seem to make a face, and ultimately decide to fly to the Moon's surface so they can see for themselves what the light and dark splotches are made of. The kids are digging again down by the Lake, and dig up a part of an old rocket. This leads Sydney to tell another "Lone Star" story, this one about how long ago, when Boxwood Terrace was called "Boxwood Territory," early astronomer Lone Star engineered and built the first rockets. This inspires the kids to engineer and build their own "foot rocket."
