I’m amazed that Spirit and Opportunity are still going. I remember when they landed and I watched the pictures they sent back nearly every day. I forgot about them for awhile, but found this image of a dust devil on Mars. Stop and think a moment. You are watching images from a remote control device, still running on solar power (5 years and going strong), that is roaming our neighboring planet.
It was just last year that
Voyager left the solar system. It was launched in 1977. It’s still going and we receive transmissions from time to time.
Although I teach Math, I bring these facts up every one in a while. Making something to last is important. Sloppy work leads to expensive mistakes. For this I provide an example of the Martian Lander that crashed into Mars because the two departments used different systems of measurement.
Now we are in the digital age – the age of communication, multi-media, and multi-tasking. It seems a great many things are ephemeral. Dot com here today and gone tomorrow. Unwanted and embarrassing pictures and stories seem to persist to the chagrin of many party-goers who now want gainful employment. But beyond that the landscape changes quickly. I wonder as we forge forth into the digital age, what will our new digital offspring build that will last. Are they up to the challenges of colonization of another planet? Can they save this one? I hope so, for my daughter’s sake.
