Earlier this month, the Jet Propulsion Laboratory in Pasadena, California had its annual two-day open house. For a laboratory complex that has the same acreage as Disneyland, it was just as crowded as the House of Mouse on a busy summer day. What a refreshing sight it was to see so many people - couples, families, grandparents and grandchildren, groups of teenagers - coming to a scientific laboratory to learn about space and science!

And how awesome to see hundreds of people in line for... not a roller coaster and not a parade, but a chance to see the next Mars Rover, Curiosity!

And Curiosity was a curious sight indeed. Visitors could only see it from a closed viewing area high above the clean room where the rover, about the size of an SUV, is being built.

Of course, no trip to JPL would be complete without a glimpse of the magnetic tape recorder responsible for storing all the data recorded by Galileo, on its journey to Jupiter in 1989. Would you believe the entire storage capacity of the drive is only 114 MB?!!

Why, yes, I do carry 36 times that amount of data in my pocket every day.
