The California Science Center in Los Angeles just launched its Samuel Oschin Air and Space Center, and the main attraction is the space shuttle Endeavour, now standing upright like it's ready for takeoff, nearly 200 feet (61 meters) tall.
Former NASA astronaut Garrett Reisman, who actually flew on Endeavour, called seeing it "overwhelming."
Free entry but reservations may cost
Entry is free, but reservations may have a cost, and there's plenty to do: try out a shuttle landing simulator or step into a cockpit replica.
You can even look inside Endeavour itself to spot its robotic arm and other cool space gear.
The center is all about getting people of any age excited about space and science through real-life exploration.
