For the rest of the two spacecrafts ' pass over the near side of the Moon, Mattingly prepared to shift Casper to a circular orbit while Young and Duke prepared Orion for the descent to the lunar surface.

For this reason it is much more common to observe a lunar eclipse from a given location.

For example, until the Tannaitic period ( approximately 10 – 220 CE ) the months were set by observation of a new crescent moon, with an additional month added every two or three years to correct for the difference between twelve lunar months and the solar year, and therefore, to keep Passover in the spring.

For example, P. Schuyler Miller called Arthur C. Clarke's 1961 novel A Fall of Moondust hard SF, and the designation remains valid even though a crucial plot element, the existence of deep pockets of " moondust " in lunar craters, is now known to be incorrect.

For example, the lunar lander test models were controlled with a joystick.

For some lunar calendars, such as the Chinese calendar, the first day of a month is the day when an astronomical new moon occurs in a particular time zone.

For precession of the lunar orbit see lunar precession.

For lunar materials, one well-studied possibility is to build mass drivers to launch bulk materials to waiting settlements.

For example, the lunar tidal acceleration at the Earth's surface along the Moon-Earth axis is about 1. 1 × 10 < sup >− 7 </ sup > g, while the solar tidal acceleration at the Earth's surface along the Sun-Earth axis is about 0. 52 × 10 < sup >− 7 </ sup > g, where g is the gravitational acceleration at the Earth's surface.

For example, if the Moon passes into the shadow of Earth and disappears from view, this event is called a lunar eclipse.

For example, in 1975, proposing to seek long-term habitability through artificial gravity and enough mass in space to allow high radiation shielding, the most ambitious historical NASA study, a conceptual 10000-person spacestation, envisioned a future mass driver base launching 600 times its own mass in lunar material cumulatively over years.

For example, in the 1970s, the gravity field disturbances above lunar maria were measured through lunar orbiters, which lead to the discovery of concentrations of mass, mascons, beneath the Imbrium, Serenitatis, Crisium, Nectaris and Humorum basins.

For an eclipse to occur, either the Moon must be located between the Earth and Sun ( for a solar eclipse ) or the Earth must be located between the Sun and Moon ( for a lunar eclipse ).

For solar eclipses, ( in 2003 ) the 39 series numbered between 117 and 155 are active, whereas for lunar eclipses, there are now 41 active saros series.

For the Apollo lunar missions, the restartable J-2 engine in the third ( S-IVB ) stage of the Saturn V rocket performed TLI.

For a few hours leading up to the first quarter, lunar craters near the line separating lit from unlit areas of the moon form a X figure from the dark craters and their lit rims.

For the Apollo programme, an adjacent spaceport, Kennedy Space Center, was constructed, and achieved the first manned mission to the lunar surface ( Apollo 11 ) in July 1969.

( For instance, for a short period of time the count of 29. 5 days per lunar month may suffice, but over 10, 000 years the number 29. 5305882 is a much more accurate choice.

For a lunar eclipse the same part of the earth will view an eclipse that is very similar to the one that occurred one exeligmos before it ( see main text for visual examples ).

For lunar missions it was fired twice: first for the orbit insertion after second stage cutoff, and then for translunar injection ( TLI ).

For example, one problem with the lunar origin theory is that the arguments for it are based upon the behavior of glass melts uses data from pressures and temperatures that are vastly uncharacteristic of and unrelated to the extreme conditions of hypervelocity impacts.

* For the lunar geological period, see Copernician

For solar eclipses the statistics for the complete saros series within the era between 2000 BCE and 3000 CE are given in this article's references.

For example, in Choctaw history, solar eclipses were attributed to black squirrels, and maize was a gift from the birds

For road uniforms, they wear a white jersey with red block numbering and Northwestern stripes on the sleeves, gray pants with blue and red stripes, and solid red socks.

For example, by Meinhof's numbering, Shona has 20 classes, Swahili has 15, Sotho has 18 and Ganda has 17.

For this reason Ganda linguists use the orthogonal numbering system when discussing Ganda grammar ( other than in the context of Bantu comparative linguistics ), giving the 10 traditional noun classes of that language.

For some schools, these plans have included the use of door numbering to aid public safety response.

For the year ( Y ) astronomical year numbering is used, thus 1 BC is 0, 2 BC is − 1, and 4713 BC is − 4712.

For each of the categories, it details the components of the numbering structure and the digit analysis required to successfully route the calls.

For the purpose of cataloging and managing the large number of documents that may be produced in the course of a law suit, Bates numbering is often applied to all documents so that each document has a unique, aribitrary identifying number.

For example a comparison of publishing histories shows that the American numbering kept roughly apace with the British up until the 16th editions in 1905, with the American editions either acknowledging the English edition, or simply matching the numbering in the 14th, 15th and 16th editions.

For these networks, the network address was given by the next 14 bits of the address, thus leaving 16 bits for numbering host on the network for a total of addresses per network.

For example, supposing there are K basic symbols, an alternative Gödel numbering could be constructed by invertibly mapping this set of symbols ( through, say, an invertible function h ) to the set of digits of a bijective base-K numeral system.

For statistical reasons, Bottrop is also divided into statistical boroughs, they are ( with their official numbering )

For the largest unit, a " Guard " numbering 1000 men, he created a new flag-red with the white double-headed eagle and his insignia ( ДI as " Danilo the First ") on it.

For historic reasons the bridge numbering continues down the Montgomery Canal and a second bridge numbering series for the Llangollen Canal begins with Rowson's Bridge ( which is numbered both 1W and 70 ).

For Operation Barbarossa, four Einsatzgruppen were created, each numbering 500 – 990 men to comprise a total force of 3, 000.

For even longer bands, the numbering starts over for numbers above 100, again starting at width 1 / 16 inch.

For an explanation of numbering and classification, see British Rail locomotive and multiple unit numbering and classification.

For convenience pen spinners have adopted a common numbering of fingers and the spaces between them (" Finger Slots ").

Between 1967 and 1973, the Chagossians, then numbering some 2, 000 people, were expelled by the British government, first to the island of Peros Banhos, away from their homeland, and then, in 1973, to Mauritius ( For the relationship between the Chagos Archipelago and Mauritius, see Chagos Archipelago ).

For example, in September 1829, John Batman ( aged 28 ), with the assistance of several " Sydney blacks " he brought to Tasmania, led an attack on an Aboriginal family group together numbering 60 – 70 men, women and children in the Ben Lomond district of north-east Tasmania.

For the first time both label names appeared on the record labels, although either the Cameo or Parkway name was emphasized, and the two series continued to use separate catalogue numbering systems.
