The first major integrated operation at Launch Pad 39B began this week with the initial tanking of a cryogenic fuel, liquid oxygen, into a giant sphere at the northwest corner of the pad. Construction of new facilities and demolition of outdated facilities also continued as Kennedy Space Center completes the transition to a multi-user spaceport.

Kennedy Space Center Water Flow Test at Launch Complex 39-B For SLS

Published on Dec 20, 2017

Water flowed during a test at Launch Complex 39B at NASA’s Kennedy Space Center in Florida. About 450,000 gallons of water flowed at high speed from a holding tank through new and modified piping and valves, the flame trench, flame deflector nozzles and mobile launcher interface risers during a wet flow test at Launch Complex 39B. At peak flow, the water reached about 100 feet in the air above the pad surface. The test was a milestone to confirm and baseline the performance of the Ignition Overpressure/Sound Suppression system. During launch of NASA's Space Launch System rocket and Orion spacecraft, the high-speed water flow will help protect the vehicle from the extreme acoustic and temperature environment during ignition and liftoff.

Preparing America for Deep Space Episode 18 On The Move

NASA Johnson
Published on Aug 31, 2018

Big progress continues to be made in 2018 for NASA’s Orion, Space Launch System (SLS), and Exploration Ground Systems (EGS) programs. Teams across America and in Europe are developing and building the spacecraft, rocket, and infrastructure necessary to send humans to deep space destinations including the Moon and beyond. Some major milestones include: Orion – Orion tank integration, Engine Gimbal System Test, and Solar Wing Test in Bremen, Germany, Structural Test Article Testing in Littleton, CO, and Exploration Mission-3 Machining in Fountain Valley, CA and Brea, CA. SLS – Application of thermal protection to Launch Vehicle Stage Adapter, Intertank Structural test article lifted to test stand at Marshall Space Flight Center (MSFC), Orion stage adapter loaded onto Super Guppy at MSFC and shipped to Kennedy Space Center (KSC). LOX Flight Hardware move to Area 6 at Michoud Assembly Facility and LH2 Structural Test Article move for thermal protection system processing at MAF. EGS – Flame Deflector Installation at Pad 39B (KSC), Crawler-Transporter 2 move to Pad 39B, Crawler lifts the Mobile Launcher, Water Deluge Test at Pad 39B.

Mind if we drop in? 🚠

Yesterday, teams with Exploration Ground Systems tested the emergency egress system T-0 release system at
@NASAKennedy
's Launch Complex 39B.

At the moment of launch, all four baskets are released from their staged position on the mobile launcher and travel down to the terminus area at the pad perimeter. This system is designed to prevent potential damage to the baskets from the launch environment, ensuring they will be ready to support future Artemis launches 🚀

Look up! 👀

This view from the pad surface of Launch Complex 39B at @NASAKennedy shows a test of the emergency egress system basket T-0 release system. At the moment of launch, this system releases the baskets away from the mobile launcher to their terminus location at the pad perimeter. The release system helps prevent potential damage to baskets during launch, ensuring they will be ready to support future @NASAArtemis missions 🚀
