The giant is waking up. NASA has announced that the massive SLS rocket for the Artemis II mission will begin its slow crawl to the launch pad on Saturday, Jan. 17. The mission will send four astronauts around the Moon, the first crewed lunar voyage in over 50 years.

The 11-million-pound stack will travel four miles on a crawler-transporter, a journey that takes 12 hours. It is a spectacle of engineering might. "We are inching closer to launch, literally," a NASA spokesperson said. The rollout marks the final phase of preparations before the crew straps in later this year.
