The coordinates of the crash site are 9 ° 8 ' north lunar latitude and 63 ° 18 ' west lunar longitude.

The spacecraft was used for tracking purposes until it impacted upon the lunar surface on command at 3. 0 degrees N latitude, 119. 1 degrees E longitude ( selenographic coordinates ) on October 11, 1967.

The spacecraft was used for tracking purposes until it struck the lunar surface on command at 14. 3 degrees N latitude, 97. 7 degrees W longitude ( selenographic coordinates ) on October 9, 1967.

The spacecraft was tracked until it struck the lunar surface on command at 2. 79 degrees S latitude, 83 degrees W longitude ( selenographic coordinates ) on January 31, 1968.

Poczobutt observed solar and lunar eclipses, comets and asteroids ( including Ceres, Pallas, Juno ), and calculated geographic coordinates of settlements in the Grand Duchy of Lithuania ( including Vilnius and Hrodna ).

* Ephemerides: It provides ephemerides of the object, that is position on sky, V magnitude, altitude, airmass, solar and lunar elongation, phase angle, galactic coordinates, R distance to the Sun, delta distance to the Earth, motion on sky, and the uncertainty on sky.

In 1750, Johann Meyer produced the first reliable set of lunar coordinates that would enable astronomers to locate features on the Moon.

Mare Tranquillitatis or the " Sea of Tranquility " would become the site chosen for the Apollo 11 lunar landing.

Mare Tranquillitatis ( Latin for Sea of Tranquility ) is a lunar mare that sits within the Tranquillitatis basin on the Moon.

The Sea of Nectar ( Mare Nectaris ) is a small lunar mare or sea ( a volcanic lava plain noticeably darker than the rest of the Moon's surface ) located between the Sea of Tranquility ( Mare Tranquillatis ) and the Sea of Fecundity ( Mare Fecunditatis ).

The name was chosen in honor of the 40th Anniversary of the first lunar landing of Apollo 11 on the Sea of Tranquility.

** Mare Tranquilitatis People's Circumlunar Zaibatsu a large space station named after the lunar feature Mare Tranquilitatis ( the " Sea of Tranquility ").

Unlike most names bestowed on lunar landmarks by Apollo astronauts, the International Astronomical Union officially recognizes the designation " Tranquility Base ".

Edu-Ware ’ s final products – the comprehensive Learning to Read literacy series, the final chapter in the Empire role-playing video game saga, a Tranquility Base lunar lander simulator, and a children ’ s game called Merry Canned Nightmare ’ s and Dreams – would each have fit well into its Science of Learning, Interactive Fantasies, Interactive Simulations, and Dragonware brands, respectively.

According to the fictional continuity of Macross construction of the SDF-2 ship began on the lunar surface at Apollo Base in November 2003.

There are in The Almagest no rules for determining in advance whether a new epicycle will be required for dealing with abberations in lunar, solar, or planetary behavior.

-- The results of microanalysis of tektites ( natural glasses of unknown origin ) for gallium and germanium have shown that these glasses are probably produced from terrestrial ( or less likely from lunar ) matter by impact of a celestial body.

The south tides in the Atlantic Ocean are semi-diurnal ; that is, two high tides occur during each 24 lunar hours.

The 28 lunar mansions are one of the most important and also the most ancient structures in the Chinese sky, attested from the 5th century BC.

* A " luni-solar calendar " is based on a combination of both solar and lunar reckonings ; examples are the traditional calendar of China, the Hindu Calendar in India or the Hebrew calendar.

A lunar calendar is one in which days are numbered within each lunar phase cycle.

Crete senesi are literally ‘ Siennese clays ’, and the distinctive grey colouration of the soil gives the landscape an appearance often described as lunar.

In addition, the lunar tables of the Julian calendar are four days ( sometimes five days ) behind those of the Gregorian calendar.

During a lunar eclipse only the umbra and penumbra are applicable.

Excluding penumbral lunar eclipses, there are a maximum of 7 eclipses in:

There are three types of lunar eclipses: penumbral, when the Moon crosses only the Earth's penumbra ; partial, when the Moon crosses partially into the Earth's umbra ; and total, when the Moon crosses entirely into the Earth's umbra.

Much as in a sunset, the atmosphere tends to more strongly scatter light with shorter wavelengths, so the illumination of the Moon by refracted light has a red hue, thus the phrase ' Blood Moon ' is often found in descriptions of such lunar events as far back as eclipses are recorded.

( where " the times of observation are in Universal time, not corrected to Newtonian time ", and 0. 0748B represents an irregular fluctuation calculated from lunar observations ).

This has been ruled as implying a requirement for the insertion of embolismic months to reconcile the lunar cycles to the seasons, which are integral to solar yearly cycles.

Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are no brighter ( indeed dimmer ) than the full moon itself.

Because there are about twelve lunations ( synodic months ) in a solar year, this period ( 354. 37 days ) is sometimes referred to as a lunar year.

Most lunar calendars are in fact lunisolar calendars.

That is, months reflect the lunar cycle, but then intercalary months ( e. g. " second Adar " in the Hebrew calendar ) are added to bring the calendar year into synchronisation with the solar year.

Some lunar calendars are calibrated by annual natural events which are affected by lunar cycles as well as the solar cycle.

The civil versions of the Julian and Gregorian Calendars are solar, because their dates do not indicate the moon phase — however, both the Gregorian and Julian calendars include undated lunar calendars that allow them to calculate the Christian celebration of Easter, so both are lunisolar calendars in that respect.

After two course correction manoeuvres ( on November 12 and 14 ) it entered lunar orbit on November 15, 1970 at 22: 00 UTC.

After two course correction maneuvers ( on November 12 and 14 ), it entered lunar orbit on November 15, 1970 at 22: 00 UTC.

Shortly after launch at 07: 30: 00 UTC on November 8, 1958, the third stage of the launch vehicle separated but failed to ignite, and Pioneer 2 did not achieve its intended lunar orbit.

After a mid-course correction the day after launch, Luna 15 entered lunar orbit at 10: 00 UT on 17 July 1969.

: and: 1 ° 23 ' for the mean diameter of the shadow of the Earth at the mean lunar distance.

He measured the ecliptic longitude of the star Spica during lunar eclipses and found that it was about 6 ° west of the autumnal equinox.

Possibly he proposed 87 ° as a lower bound since gauging the lunar terminator's deviation from linearity to 1 ° accuracy is beyond the unaided human ocular limit ( that limit being about 3 ° accuracy ).

A 245-kilogram instrument compartment separated from the main bus, which was in a 350 x 1, 000-kilometer orbit inclined at 71. 9 ° to the lunar equator.

The Luna 16 automatic station was launched toward the Moon from a preliminary Earth orbit and after one mid-course correction on 13 September it entered a circular 111km with 70 ° inclination lunar orbit on 17 September 1970.

After two mid-course corrections en route to the Moon, Luna 17 entered lunar orbit and then landed on the lunar surface at 03: 46: 50 UT on 17 November 1970 at 38 ° 17 ' north latitude and 35 ° west longitude, about 2, 500 kilometers from the Luna 16 site in the Sea of Rains.

Frame by frame coverage of the lunar surface was obtained over 360 ° in azimuth and from + 40 ° above the plane normal to the camera z-axis to 65 ° below this plane.

The temperature at this site is also more favorable than at more equatorial latitudes as it does not experience the daily temperature extremes of 100 ° C when the Sun is overhead, to as low as − 150 ° C during the lunar night.

ISRO had reported on 25 November 2008 that Chandrayaan-1's temperature had risen above normal to 50 ° C, scientists said that it was caused by higher than normal temperatures in lunar orbit.
