The museum must assemble scaffolding for that installation to take place. Once the solid rocket motors are installed, the final piece to complete the solid rocket boosters are the tips-the so-called forward assembly, including the nose cones and forward skirts. If it doesn't, then every pin takes some banging and pounding to get the pin in," Rudolph said. "If everything, as they lower it in and put it in, aligns really well, the pins basically slide right in. Each pin is 1 inch in diameter and about 2 inches long. The installation of the pins could take a few hours or last into the night.

"But then what will take more time-hopefully not too much more time, but potentially a lot more time-is putting the approximately 180 pins in that attach the solid rocket motor to the aft skirt," Rudolph said. Tuesday's work should begin around 8 a.m., and it probably will take an hour to lift the rocket into place. Each rocket will be installed atop the solid rocket booster's base-the aft skirts, which are 9 feet tall and were moved into place in July. The placement will be completed using two cranes-a small one that will lift the rockets from a horizontal position to a vertical one, and a large one that will hoist them into place.

The second motor will be installed no earlier than Nov. The museum expects to livestream the installation. The first significant action begins Tuesday, when the science center will lift the first solid rocket motor into place. On Monday, the motors will be moved from their current location-next to the museum's dining terraces-a few hundred feet closer to the construction site. At liftoff, the white solid rocket boosters were set underneath Endeavour's wings and produced more than 80% of the lift during takeoff. Each solid rocket motor measures 116 feet and makes up most of the length of the 149-foot solid rocket boosters. This is the first big tall pieces of the stack going into the building," California Science Center President Jeffrey Rudolph said. The two solid rocket motors-each weighing 104,000 pounds and the size of a Boeing 757 fuselage-were transported by truck in early October from Mojave Air and Space Port to the science center in South Los Angeles.
