Attached here is a photo of a SpaceX Dragon capsule falling to an ocean landing in the Pacific off southern California yesterday. In this photo, there is a lesson for celestial navigation. Can you see it?? There is also a calculation that can be worked, dependent on that lesson, using some angular basics.The photo was taken from a support ship. Can you estimate how far the support ship is from the spacecraft? Note that each parachute has a diameter of approximately 115 feet. This would only be a very rough estimate, maybe good to within a factor of two or three, but better than nothing.
