Tracking Juno

As with the MSL and New Horizons missions, my eleven-year-old son and I have been using NASA's Eyes On The Solar System program to track the progress of the Juno probe due to arrive at Jupiter next month. It's pretty cool. From the position of Juno you can now make out the growing disk of Jupiter. With MSL I made a scale model of the progress of the craft by drawing a 2 cm chalk dot at the top of the driveway to represent Mars. Each day we'd go out and measure how far the spacecraft was from Mars and make a mark there. I think It's time to work out a scale so we can do the same with Juno.
