NASA’s Marshall Space Flight Center removed two of its historic test stands – the Propulsion and Structural Test Facility and the Dynamic Test Facility – with carefully coordinated implosions on Saturday. The demolition of these historic structures is part of a larger project at Marshall that began in spring 2022, targeting several inactive structures and building a dynamic, interconnected campus ready for the next era of space exploration.

Jared Isaacman, Trump’s nominee to lead the space agency, said the demolition would make way for the next chapter in the U.S. space mission.

“NASA is embarking on an exciting infrastructure modernization effort to prepare for the future of exploration,” Isaacman told Fox News Digital in a statement. “The first phase will make way for new facilities by retiring outdated ones, enabling investments in the capabilities needed to deliver on our world-changing mission of science and discovery.”

Redstone said the demolitions would cause a “significant noise event,” and personnel on certain parts of the arsenal were directed to wear hearing protection.
