Short one

Not much to say today. I didn't do anything last night, just some laundry. I did remember something I meant to put in yesterday's journal. I read about a Japanese probe which was headed for Mars. Well they launched it into space last year and due to some sort of error and then damage to the probe it is just orbiting earth. However they are now sending signals to it and reprogramming it so it will leave our orbit and be on its way to Mars. I found it fascinating that they can not only do the calculations to take it out of orbit using its current information, but also program it from Earth. Which led me to this question. What do you all think is the most amazing thing we have accomplished? The internet, skyscapers, moon landing, artificial hearts, cloning, cars?
