The last one.

ET-94, the last Space Shuttle fuel tank, rolled through Los Angeles Saturday to its new home at the California Science Center.

This one hasn't been to space. Shuttle fuel tanks are designed to disintigrate once the Space Shuttle has used them to rocket past the earth's atmosphere.

Any concerns about L.A. traffic jams were set aside because this is one big honkin' orange tank! When it turns the corner, yield baby.

Real time, not slow motion: the fuel tank turns into the on-ramp back to Lincoln blvd #ETComesHome #SpotTheTank pic.twitter.com/jV0bMS6MR9

I loved what Paula Madison, a member of the Center's Board of Trustees, said:

Look at it, against the night sky and moon and stars, and think of all the thousands of kids who are going to see this. They are going to say, ‘People made this. And so can I.'

So much fun to watch a gigantic NASA relic roll down the street! And check out the ingenious helmets these kids wore!

It's going to be such a great exhibit. Thanks for donating ET to a museum, NASA!
