Some many years ago, i was sitting in the beach at night, watching the clear sky and the stars in August, when suddenly i saw something strange. One star was moving slowly to one straight direction, and after a while it just disappeared! Frankly, i do not believe in ghosts, nor that aliens are watching us. I assumed that it was some kind of space debris, or orbiting sat or the ISS, and i suppose that i was right.
But hey, there is something new moving in the skies! It is the Nanosail, with its large 10 by 10 meters sails, able to reflect sun light in the black sky at night! Believe it or not, you can see it with your own eyes! No telescope needed. So, how can you locate it. First, you visit heavens-above.com or spaceweather.com. Then, after setting your location on the map, the page returns the date and time that the nanosail (or other satellite) passes from above. With some luck, it may turn to the proper angle and reflect the sun light downwards, and reveal it's position.
