Shuttle Endeavour’s final mission for a new home and space exploration
Makenna Cramer checked out the museum's expansion and significance to L.A. and space exploration in December.
After years of construction, the California Science Center’s expansion in Exposition Park will be open to the public on Nov. 13, officials announced Wednesday.
The Samuel Oschin Air and Space Center is a 200,000-square-foot addition to the museum and space shuttle Endeavour’s new, permanent home.
According to officials, it’ll be the only place in the world where guests can see a complete, authentic space shuttle system displayed in launch position — just like it would look before it blasted off from the Kennedy Space Center in Florida.
Endeavour spans about 20 stories tall in the Samuel Oschin Shuttle Gallery, one of three main galleries that will be filled with hands-on exhibits and authentic aerospace artifacts. The center will be free to visit.

Preparing for the public
The Samuel Oschin Air and Space Center finished construction around Endeavour earlier this year, after each of the space shuttle components were lifted into place in the construction zone.

The city had requested six additional years to ready the projects for construction.
The roughly six-month process of attaching the flown orbiter — Endeavour — to twin solid rocket boosters and the last remaining flight-qualified external tank was called “Go For Stack.” Museum officials said the complex process had never been done outside of a NASA facility.
The space shuttle has been hidden from public view for more than two years since Endeavour reached for the stars one last time in the “Go For Stack” mission — at least until now.

As its name suggests, Endeavour is the centerpiece of the Samuel Oschin Shuttle Gallery. It was the last gallery to be unveiled by the California Science Center, months after offering sneak peeks of the Korean Air Aviation Gallery and Kent Kresa Space Gallery.
The shuttle gallery shows how the first reusable spacecraft helped humans live and work beyond Earth’s surface in low orbit, according to the museum. Officials said it preserves a critical part of space exploration — Endeavour was the last orbiter to join the shuttle fleet, traveling more than 122 million miles on over two dozen missions.

Beyond the historical significance, it’s designed to inspire the next generation of explorers, scientists and engineers by offering "unparalleled" views of the space shuttle, according to the museum.
The finishing touches
The California Science Center still has a lot of work to do before the first guests walk into the Samuel Oschin Air and Space Center in around five months.
With Endeavour and many major pieces in place, including the front of a Boeing 747 and jets suspended from the ceiling, attention turns to adding all the interactive exhibits that will make the space come to life.
The first of many artifacts have been installed in the Kent Kresa Space Gallery, including a space shuttle main engine (right) and a solid rocket booster segment.

The roughly 20 aircraft that’ll be displayed — some already suspended from the ceiling — were selected by the California Science Center for the engineering principles they can teach.
