ST. PAUL (AP) - Houston, we have moon rocks.

The Minnesota National Guard has found a few small fragments of the moon's surface in storage in a state building in St. Paul.

The moon rocks came from the Apollo 11 moon landing in 1969, when astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon. Some of the rocks they collected from the moon's surface have since gone missing.

Minnesota's moon rocks came from President Richard Nixon, who also presented a Minnesota state flag that was carried on the mission.

The National Guard will deliver the moon rocks to the Minnesota Historical Society at an event Wednesday before students at STARBASE Minnesota, a math and science program.
