NASA took almost 12 hours to move its gigantic Space Launch System (SLS) Moon rocket and Orion Space Capsule from Kennedy Space Center to a launch pad about 4 miles (6.4 km) away. The rocket moved very slowly, at just 0.82 mph (1.3 km/h). This careful journey happened on Saturday. The rocket is part of the Artemis II mission but will not launch before 6 February. The mission will last about 10 days and plans to send four astronauts farther into space than anyone before. It aims to prepare for a human landing on the Moon’s surface, the first since 1972.
