(navigation)

Approach

 

in space navigation, a series of consecutive maneuvers by which one spacecraft is brought into close proximity to another. The aim of approach may be inspection, mooring, or assembly in orbit. Inspection, for example, entails the examination of a spacecraft at close range in order to determine the necessity of repairs. Mooring involves the temporary linking of two spacecraft with a flexible line.

Approach may be accomplished in two ways. In one technique only the final distance separating the two spacecraft is critical, and the closing speed at the moment of closest approach is not a factor. In the second technique the closing speed up to the moment of closest approach should be very low, ideally zero. This second technique requires larger expenditures of fuel than the first.

Approach requires that the two spacecraft be equipped with radio communications systems, computers, rocket engines, and navigation control systems. The active spacecraft carries out the search, maneuvering, and approach missions, while the second one is passive.

The first approach of two spacecraft with crew participation was carried out by the American spacecraft Gemini 6 and Gemini 7 in 1965. The first approach of three spacecraft with crew participation was carried out by the Soviet spacecraft Soyuz 6, Soyuz 7, and Soyuz 8 in 1969.

Their apprehensions arise from several changes they dread in the celestial bodies: for instance, that the earth, by the continual approaches of the sun towards it, must, in course of time, be absorbed, or swallowed up; that the face of the sun, will, by degrees, be encrusted with its own effluvia, and give no more light to the world; that the earth very narrowly escaped a brush from the tail of the last comet, which would have infallibly reduced it to ashes; and that the next, which they have calculated for one-and-thirty years hence, will probably destroy us.

The first and best-framed oligarchy is that which approaches near to what we call a free state; in which there ought to be two different census, the one high, the other low: from those who are within the latter the ordinary officers of the state ought to be chosen; from the former the supreme magistrates: nor should any one be excluded from a part of the administration who was within the census; which should be so regulated that the commonalty who are included in it should by means thereof be superior to those who have no share in the government; for those who are to have the management of public affairs ought always to be chosen out of the better sort of the people.
