Vacation, part 2

Here are four more pictures I took during my recent trip to the Science Museum in Oklahoma City.  The top picture shows a play area for children.  This must be a tree house to top all tree houses.

There is an area in the museum dedicated to space exploration.  The next picture shows a space capsule painted orange and white.  As to the words "F 6 Adios MF,"  I don't have a clue about that.

Next picture shows a rocket engine which is used to lift rockets into space.  To get some idea of its size, look are the artwork hanging on the wall at the center left.

The last picture shows the planets Saturn and Jupiter as models.
