Humans built a machine and sent it to Mars.
I am impressed by relatively simple technologies like cars, phones, cameras and computers, all of which have embedded themselves in our lives over the past century. The “Curiosity” rover takes all of these amazing inventions from our planet and brings them to another. The effort and cost is astronomical, but exploring our universe is priceless. We may not discover life on Mars, but we have reached beyond our own mortal, earth-bound lives to expand our celestial consciousness and seek understanding of our greater place in the eternal mystery of our existence.
