Two Northrop Grumman five-segment solid rocket boosters will launch the first crewed flight of NASA’s Space Launch System (SLS) rocket from Pad 39B at Kennedy Space Center, Florida, as early as February 6, 2026, as part of the Artemis II mission.

The SLS boosters are the world’s largest and most powerful solid rocket boosters to ever be flown on a human spaceflight mission, standing 177 feet tall and producing 3.6 million pounds of thrust each. Evolved from the four-segment shuttle-era design, the boosters contributed over 75 percent of the SLS rocket’s thrust and performed as twins during Artemis I, the successful first launch of the rocket and uncrewed Orion spacecraft.
