Space Launch System or SLS is the most powerful vehicle built yet by NASA to launch the Orion spacecraft for its historic lunar mission on February 6, when four astronauts will fly towards the moon, after 54 years since 1972. In terms of raw power, it stands a few inches shorter than its SpaceX cousin Starship; however, SLS proved its mettle last year with its uncrewed 25-day flyby mission to the moon and back.
The 320 feet tall rocket will carry the Orion spacecraft with NASA astronauts Reid Wiseman, Victor Glover, and Christina Hammock Koch, along with Jeremy Hansen of the Canadian Space Agency. Initially planned for a 2024 launch, the mission got extended until next month 2026 and NASA is expediting Artemis II, as the US govt under the Trump regime seeks to lead the space race with a crewed lunar landing with Artemis III.
The first phase of the launch is by rolling out the big boy towards the launch center from the Vehicle Assembly Building to Launch Pad 39B.
It will take a total of 12 hours to cover the nearly four-mile journey as the 11-million-pound SLS will be lugged on the back of the trusty crawler-transporter 2.

11 million pounds. Four miles. 12 hours.
These are what the numbers look like for transporting a stacked Moon rocket from the Vehicle Assembly Building to Launchpad 39B. @NASAKennedy teams are targeting no earlier than 7am ET on Jan. 17 for rollout. https://t.co/nsXZfFX6y1 pic.twitter.com/TUCqcHAbUp

Nice and slow, team. You break it, you buy it.
