"It wasn’t that hard to figure out," Van said. Other national governments already knew about the KH-13. It was the business of their intelligence services to figure such things out. So Van had used French commercial SPOT satellite photos, easily purchased through the Internet. Using these photos, Van had watched Indian scientists at various Indian nuclear weapons centers busily moving their cars and trucks to baffle the KH-13. The Indians were doing their usual denial and deception efforts against the new American spy satellite, trying to disguise the feverish activity in and out of their nuclear weapons centers. Given the Indians’ keen awareness of the KH-13’s orbit, it was easy for Van to download a PC simulator program from Dottie’s astrophysics lab, and deduce the satellite’s orbit by himself. Dottie was happy to help him find the right program, and she had never suspected a thing.
