Origin First Firmament In the beginning, there was only one universe, the First Firmamentperfect but alone. It decided to create life: While some of them industriously worshipped it, seeking its approval whenever they created life on their own, which prompted the First Firmament to name them " Aspirants "; others, "multicolored rebels",  who were "as many as the stars themselves",  wanted their own creations to evolve, for the universe to grow, change and die. That was seen by the First Firmament as madness and sacrilege.
In the adjacent image, the two circles on the map represent lines of position for the Sun and Moon at GMT on October 29, At this time, a navigator on a ship at sea measured the Moon to be 56 degrees above the horizon using a sextant.
Ten minutes later, the Sun was observed to be 40 degrees above the horizon. Lines of position were then calculated and plotted for each of these observations. Since both the Sun and Moon were observed at their respective angles from the same location, the navigator would have to be located at one of the two locations where the circles cross.
In most cases, determining which of the two intersections is the correct one is obvious to the observer because they are often thousands of miles apart. As it is unlikely that the ship is sailing across South America, the position in the Atlantic is the correct one.
An observer in the Gran Chaco point would see the Moon at the left of the Sun, and an observer in the Madeira point would see the Moon at the right of the Sun. Angular measurement[ edit ] Using a marine sextant to measure the altitude of the sun above the horizon Accurate angle measurement evolved over the years.
One simple method is to hold the hand above the horizon with one's arm stretched out. The width of the little finger is an angle just over 1. The need for more accurate measurements led to the development of a number of increasingly accurate instruments, including the kamalastrolabeoctant and sextant.
The sextant and octant are most accurate because they measure angles from the horizon, eliminating errors caused by the placement of an instrument's pointers, and because their dual mirror system cancels relative motions of the instrument, showing a steady view of the object and horizon.
Navigators measure distance on the globe in degreesarcminutes and arcseconds. A nautical mile is defined as meters, but is also not accidentally one minute of angle along a meridian on the Earth. Sextants can be read accurately to within 0. Most ocean navigators, shooting from a moving platform, can achieve a practical accuracy of 1.

September Learn how and when to remove this template message Practical celestial navigation usually requires a marine chronometer to measure time, a sextant to measure the angles, an almanac giving schedules of the coordinates of celestial objects, a set of sight reduction tables to help perform the height and azimuth computations, and a chart of the region.
Two nautical ship officers "shoot" in one morning with the sextant, the sun altitude With sight reduction tables, the only calculations required are addition and subtraction.
Most people can master simpler celestial navigation procedures after a day or two of instruction and practice, even using manual calculation methods.
Jul 28, · Advances in robotics and remote manufacturing offer tantalizing prospects for designers as they map out ways to explore and use resources in the solar system. Study: Asteroids Provide Sustainable Resource | NASA. Automated Algebraic Manipulation in " Celestial Mechanic, s William H. Jefferys processors for use in celestial mechanics are considered puting Machinery. This is . The most important tool used by Columbus in his celestial attempts was the quadrant. This was a metal plate in the shape of a quarter-circle. From the center of the circle hung a weight on a string, that crossed the opposite edge of the circle (see figure 1).
Modern practical navigators usually use celestial navigation in combination with satellite navigation to correct a dead reckoning track, that is, a course estimated from a vessel's position, course and speed.
Using multiple methods helps the navigator detect errors, and simplifies procedures. When used this way, a navigator will from time to time measure the sun's altitude with a sextant, then compare that with a precalculated altitude based on the exact time and estimated position of the observation.
On the chart, one will use the straight edge of a plotter to mark each position line. If the position line indicates a location more than a few miles from the estimated position, more observations can be taken to restart the dead-reckoning track.
In the event of equipment or electrical failure, taking sun lines a few times a day and advancing them by dead reckoning allows a vessel to get a crude running fix sufficient to return to port. One can also use the Moon, a planet, Polarisor one of 57 other navigational stars to track celestial positioning.
Latitude[ edit ] Latitude was measured in the past either by measuring the altitude of the Sun at noon the "noon sight"or by measuring the altitudes of any other celestial body when crossing the meridian reaching its maximum altitude when due north or southand frequently by measuring the altitude of Polaristhe north star assuming it is sufficiently visible above the horizon, which it is not in the Southern Hemisphere.
Polaris always stays within 1 degree of the celestial north pole. If a navigator measures the angle to Polaris and finds it to be 10 degrees from the horizon, then he is about 10 degrees north of the equator.
This approximate latitude is then corrected using simple tables or almanac corrections to determine a latitude theoretically accurate to within a fraction of a mile. Angles are measured from the horizon because locating the point directly overhead, the zenithis not normally possible.
When haze obscures the horizon, navigators use artificial horizons, which are horizontal mirrors of pans of reflective fluid, especially mercury historically.Modern practical navigators usually use celestial navigation in combination with satellite navigation to correct a dead reckoning track, that is, a course estimated from a vessel's position, course and speed.
Using multiple methods helps the navigator detect errors, and simplifies procedures. The real disadvantage is that you cannot use methods of celestial navigation when the skies are cloudy, as you need to be able to see the stars or sun in order to use it.
