figure out how significant they may be. you have seen pictures of the images from the chinese satellite. what do you think it might be? any reason for hope? any differentiation in the images we saw earlier in the week? >> one of the interesting things you can notice when you look at the images we saw earlier in the week released by australia, they gave one of the dimensions for the larger object as 24 meters. this one, they are saying is about 22 meters wrong. there's a little margin for error there. if there's measuring difficulty, they might be the same object. they both looked relatively rectangular. this one was sighted 120 kilometers from the australian items. given the difference in times between when the images were required, that would imply an average surface speed of 2.5
