English: Progress on the new brick walls of the north side of the flame trench at Launch Pad 39B is seen in a view from the top of the pad at NASA’s Kennedy Space Center in Florida. Construction workers with J.P. Donovan of Rockledge, Florida, continue to install new heat-resistant bricks on the concrete walls. The Pad B flame trench is being refurbished to support the launch of NASA’s Space Launch System rocket. The Ground Systems Development and Operations (GSDO) Program at Kennedy is helping transform the space center into a multi-user spaceport and prepare for Exploration Mission 1, deep-space missions, and the journey to Mars.
