2, NAVIGATION BY THE STARS Steering the Mother Ship: Imaginal Reckoning Audio commentary (to be added), explaining the basic astronomy needed to crew on the navigation deck of the mother ship, Terra Navis, and including an explanation of the imaginative or mythogenetic factor of navigation. The BEM, barycenter-earth-moon, is the point of shared mass or center of gravity between earth and moon. That is, the fulcrum of shared mass in the earth-moon coupling, like the fulcrum of a see-saw. Astronomical law says that with two bodies locked in a mutual gravitational dynamic, the center of shared mass will be displaced toward the larger body in proportion to its multiple of mass compared to the lesser body. The mass of the earth is 81 times greater than the mass of the moon. Therefore the barycenter of the earth-moon system is displaced by 81 units from the moon, of lesser mass, toward the earth, of greater mass. The mean distance from earth to moon is 230,100 miles. I/81th of this distance is about 2840 miles. The radius of the earth is about 3950 miles. So, measuring out from the center of the earth and subtracting this unit (1/81th) from the radius, you get 1110 miles. This is the average distance of the barycenter beneath the surface of the earth. The common center of mass in the earth-moon system is displaced so far toward the body of greater mass, the earth, that it falls within the physical body of the earth. NOTE: The orbits of all planets in the solar system are elliptical or oval shaped. They all have an extreme near and distant point, but they are not called apogee and perigee because these terms refer uniquely to the moons distance from the earth (-gee, i.e., gaia). For the other planets, including the earth, these points are described by terms indicating distance from the sun: -helion. The perihelion (pl. perihelia) is the near point, the aphelion (pl. aphelia), the far point on the oval of each planetary orbital path. These planetary apsides are stable and remain positioned at 180-degrees opposition to each other. The apsides of some planets, notably the earth, saturn, and jupiter, play an important role in assessing Sophias correction. The barycenter, along with the apogee and perigee points on the elliptical lunar orbit, is the steering mechanism by which Gaia sets and follows a course through the galactic currents, traversing the region of the galactic spiral arms where the solar system (fleet) is located. As we begin to realize that the earth is a celestial body capable of self-propelling motion, we may well wonder how the planet handles its journey, how it steers and navigates on its own power. Not only can we discover how she does so, but we can even participate in how the earth sets its course and and steers itself on its way, navigating by the stars. Tracking the earths celestial journey in real time is the elective mission of the navigational crew on the mother ship, Terra Navis.
