Technicians are shown at NASA’s Launch Pad 39B at Kennedy Space Center in Florida in Florida on Tuesday, Feb. 10, 2026, with one of two side flame deflectors that will be used to support NASA’s Artemis II launch. Each side flame deflector has two pillar-like extensible columns which are jacked into place to help support mobile launcher 1 when the vehicle is being fueled. During liftoff, the flame deflectors help contain the plume of the SLS (Space Launch System) rocket down into the flame trench.
