🍀Happy St. Patrick's Day🍀

Big schedule boards like this were used to keep Space Mission Projects organized and on track at Mound Laboratory. This particular board was tracking the development of the Multi Hundred Watt RTG for LES8&9 or the Lincoln Experimental Satellites 8 & 9. Someone decided to make the board festive by adding a clover!

📸Schedule Board from March 15, 1974.

If you know a fellow former Mound employee who might want to participate, please pass this along — we would love to hear from as many people as possible. If you are out of town, or need to make other arrangements, please reach out.

Yesterday, several members of the Mound Science and Energy Museum Association (MSEMA) Board and former Mound Lab Employees attended the grand opening of the Mound Cold War Discovery Center Exhibit at Carillon Historical Park.

The journey to preserve and share the legacy of Mound Laboratory has been a long, collaborative project, started by the dedicated efforts of former Mound Lab Employees and assisted by the Department of Energy, the City of Miamisburg, passionate community members, local historians and history lovers. While this project has had its challenges, it is safe to say that this exhibit is one of the many ways we have come together to honor Mound Laboratory, its technology, scientific contributions, and the people who worked there.

The Mound Science and Energy Museum Association Board is thrilled that Mound's story will be shared with the thousands of people that visit Carillon Park each year. And, the Board is excited to work with the Miamisburg Historical Society to keep parts of the Mound Legacy in Miamisburg with a new exhibit.
