About a dozen technicians and engineers from Exploration Ground Systems worked together recently at NASA’s Kennedy Space Center to carry out the first step in stacking the twin solid rocket boosters that help launch NASA’s Space Launch System (SLS) rocket for the first Artemis lunar mission

Inside the KSC’s Rotation, Processing and Surge Facility, the NASA and Jacobs team completed a pin. The pinning activity involved using bolts to attach one of five segments that make up one of two solid rocket boosters for SLS to the rocket’s aft skirt. A crane crew assisted in mating the aft segments to the rocket’s two aft skirts.

A handful of the team members gained pinning experience on boosters for the space shuttle, while the rest were first-time pinners. Pablo Martinez, Jacobs TOSC handling, mechanical and structures engineer, inserted the first of 177 pins per joint to complete the first official step in stacking the SLS boosters.
Manufactured by Northrop Grumman in Utah, the 177-foot-tall twin boosters provide more than 75 percent of the total SLS thrust at launch. SLS is the most powerful rocket NASA has ever built.
The SLS rocket will launch NASA’s Orion spacecraft and send it to the Moon for Artemis I — a mission to test the two as an integrated system, leading up to human missions to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon by 2024.
