Workers with NASA???s Exploration Ground Systems (EGS) paint the bright red NASA ???worm??? logo on the side of an Artemis II solid rocket booster segment inside the Rotation, Processing and Surge Facility (RPSF) at Kennedy Space Center in Florida on Tuesday, Jan. 30, 2024. The EGS team used a laser projector to mask off the logo with tape, then painted the first coat of the iconic design. The booster segments will help propel the Space Launch System (SLS) rocket on the Artemis II mission to send four astronauts around the Moon as part of the agency???s effort to establish a long-term science and exploration presence at the Moon, and eventually Mars.
