Mat Kaplan’s Huntsville, Alabama trip wraps up with a tour of the historic and history-making Marshall Space Flight Center. Join him at the control center for research underway on the International Space Station, under a tent where a critical component of the Space Launch System rocket is getting finishing touches, in a conversation about the Fermi spacecraft’s search for the universe’s biggest explosions, and with the Center’s Associate Director for Technical efforts. Wrap up with Bruce Betts and the anniversaries of one fictional and one factual explorer of deep space.
