Missouri’s missing moon rock has been found and returned.

The rock collected during the last Apollo mission–Apollo 17–had been in Senator Bond’s office in Washington. President Nixon had given it to Missouri while Bond was Governor. Bond had taken it with him when his term as Governor ran out and when he was later elected to the Senate. His staff found it while sorting through the archives of his Senate office.

Bond has given the rock to Governor Nixon, who will display it in his office for a month before it goes to the Department of Natural Resources. Missouri also has some tiny chips of moon rocks from the Apollo 11 mission, the first one that landed on the moon.

The last Apollo moon flight was 28 years ago this month.
