Science Center officials said the shuttle’s rocket booster assembly has been completed with addition of the “forward assembly” — or cone-shaped tops — to the boosters.

The Artemis I mission’s rocket engines and boosters have direct ties to Columbia, Challenger and each of the other shuttles, and even one of the original Mercury 7 astronauts.

The Space Shuttle, for reference, had just three main liquid-fueled rocket engines, along with two solid boosters.

The three parts that made up the space shuttle were the orbiter - the part that resembled an aeroplane, the large orange external tank and the 2 solid rocket boosters.

The reusable boosters produced more than 6 million pounds of thrust during liftoff, igniting only after the space shuttle’s main engines were at full thrust, according to the science center.

The last big transport of shuttle equipment to the California Science Center will traverse seven freeways to be installed at a 20-story museum exhibit.
