In Photos: NASA's Kennedy Space Center Renovates Launch Pad 39B for Orion

Launch Complex 39B at NASA's Kennedy Space Center in Florida is getting a makeover. After launching missions for the Apollo, Skylab and space shuttle programs, Pad 39B has been upgraded and modified in preparation for NASA's Space Launch System (SLS) and the Orion crew capsule.

The modernized pad will support the launch of Exploration Mission 1, the first uncrewed test flight of the SLS and Orion, currently scheduled for mid-2020. Built for versatility, it will also be able to support commercial launch providers. Click through this gallery to see Pad 39B's new look!

On Oct. 15, 2018, NASA successfully tested a water-deluge system at Pad 39B that will reduce the extreme heat generated by launches of the agency's in-development Space Launch System rocket. The so-called "Ignition Overpressure Protection and Sound Suppression" system can spew nearly half a million gallons of water up to 100 feet (30 meters) into the air above the launch pad.

During a flow test of the new water deluge system on Oct. 15, 2018, about 450,000 gallons of water was blasted from a holding tank, soaking the flame trench, flame deflector nozzles and mobile launcher interface risers.

During the test, water erupted into the air like a geyser. But this won't be the case during an actual rocket launch. When the mobile launch tower is in place on the pad for a rocket launch, that water will flow through pipes inside the structure and flow out of the nozzles. 

Here's what the launch platform looks like when it's not being drenched by the Ignition Overpressure Protection and Sound Suppression water deluge system.

The water tower at Pad 39B was not replaced, but workers sandblasted the structure during the renovations to make it look as good as new. 

NASA conducted another test of the water deluge system at Launch Complex 39B on May 24, 2018. "The high-speed water flow will help protect the vehicle from the extreme acoustic and temperature environment during ignition and liftoff," NASA officials said in a description of the test. 

In this view from inside the flame trench at Pad 39B, you can see the new flame deflector. NASA refurbished the trench by installing new heat-resistant bricks in the walls.
