Lunar Nomenclature DatabaseĬrater visible in the iconic "Earthrise" colour photograph, taken aboard Apollo 8 by W. ![]() For example, in the Origin section for the crater named Wolff, the tilde in “Christian, Baron von ~” denotes where “Wolff” appears in the honoree’s full name. – A tilde (~) in the Origin section shows the placement of the last name (surname), Latinized or honorific name in the given name of the person for whom the Feature Name was designated. For example, if the designation is for a person, that person’s last name appears in the Feature Name column, with their given name, birth/death dates, and a synopsis of their achievements in the Origin section. ORIGIN – A brief overview of who (or what) the feature was named to honor. LON – The estimated longitude at the approximate center of the feature. LAT – The estimated latitude at the center center of the feature. If no value is shown – such as 0.00 km – it does not necessarily mean that the diameter is zero it can mean that no valid measurement is available. – An asterisk (*) denotes that the designation is honorary.ĭIA – The estimated diameter of the feature (if available) in kilometers. In some instances, it denotes that a designation was removed or vacated in order to be reassigned with a new designation. † – A feature name followed by a † signifies that the designation is not considered official, but may be generally accepted. In several cases, a significant (large) crater has numerous smaller “satellite” craters adjacent to it that are named for the same entity, but with a letter (A-Z) or symbol (such as β or δ) appended to it. Searching “ rima” will find all rimae (linear rilles, or fissures) on the Moon, etc.įEATURE NAME: The entity – usually a person – after which the feature was named (or designated). PRO TIP 2: Searching “ lacus” will find all lakes on the Moon. PRO TIP 1: When searching, a partial word (such as “ dan“) will find all features with that include those letters in sequence (such as “ Daniel,” “ Daniell,” “Car danus,” “ Danjon,” “ Danish,” etc. (Clicking Copy copies the data to your clipboard in raw text form.)

In addition, the LROC team used improved ephemeris provide by the LOLA and GRAIL teams and an improved camera pointing model to enable accurate projection of each image in the mosaic to within 20 meters.įor more information about this product, check out the featured image.A sortable compendium of all known and named significant craters, mountains, rilles, scarps, valleys and other geographical features on the Moon.Īll columns are sortable – either alphabetically (A-Z or Z-A) or numerically (ascending or descending) – by clicking the ▲ arrow at the top of the column. ![]() A polar stereographic projection was used in order to limit mapping distortions when creating the 2-D map. The LROC Northern Polar Mosaic (LNPM) is likely one of the world’s largest image mosaics in existence, or at least publicly available on the web, with over 680 gigapixels of valid image data covering a region of the Moon (2.54 million km², 0.98 million miles²) slightly larger than the combined area of Alaska (1.72 million km²) and Texas (0.70 million km²) - at a resolution of 2 meters per pixel! To create the mosaic, each LROC NAC image was map projected on a 30 m/pixel Lunar Orbiter Laser Altimeter (LOLA) derived Digital Terrain Model (DTM) using a software package called Integrated Software for Imagers and Spectrometers (ISIS). The LROC team assembled 10,581 NAC images, collected over 4 years, into a spectacular northern polar mosaic. As a result, the Lunar Reconnaissance Orbiter Camera (LROC) archive now contains complete coverage from 60°N to the north pole (except of course for areas of permanent shadow) with a pixel scale of 2 meters. The increased altitude over the northern hemisphere enables the two Narrow Angle Cameras (NACs) and Wide Angle Camera (WAC) to capture more terrain in each image acquired in the northern hemisphere. After two and a half years in a near-circular polar orbit, LRO entered an elliptical polar orbit on 11 December 2011 with a periapsis (point where the LRO is closest to the surface) near the south pole, and the apoapsis (point where LRO is furthest from the surface) near the north pole. On 18 June 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO) to map the surface of the Moon and collect measurements of potential future landing sites as well as key science targets.
