An empty space shuttle tank known as the ET-94 ended its journey to the California Science Center in Exposition Park Saturday.
It could remain there for years before it gets linked up with the Space Shuttle Endeavor in a new facility.
Spectators lined the streets to watch the enormous tank make its way from Marina del Rey, where it departed from early Saturday.
The 66,000 pound tank spent the next 18 hours slowly moving through 16 miles of surface streets in Los Angeles and Inglewood.
Before that, it traveled over 4,4000 nautical miles by barge from New Orleans and passing through the Panama Canal on its way to Marina del Rey.
"This is huge...this is a huge tank, said Muchaka Zukinta, of Bellflower. “I didn't think it was that big, but it's bigger than I thought it was.”
A donation from NASA, ET-94 was built as a sister tank for the space shuttle Columbia, but never used.
After Columbia was destroyed on its return back through the atmosphere following in 2003, ET-94 was used as part of the investigation into the disaster. Many pieces of foam were removed from the tank, and it will need some restoration before being put on display at the California Science Center, according to the museum.
The ET-94 is the last remaining tank in existence.
Once it is settled and joined with the Endeavor, the science center will be the only place in the world people can see a complete shuttle stack with a real flight hardware in launch configuration, according to the museum.
"It's one of those must-see things,” said Bakersfield resident Linda Lowry. “You have to do it."
