The Map of Polar regions of the Moon from +-55 degrees shows relief of the surface, landing sites of Chandrayaan-3 spacecraft and impacts of Luna 25 and other spacecrafts

It is the Map of Polar Regions of the Moon

The selection of a location for a lunar base involved criteria based on scientific and practical needs, including temperature comfort, continuous solar illumination, Earth visibility, and access to lunar regolith for construction. The Moon's polar regions, especially the South Polar region at the Shackleton crater's shaft, were chosen due to their...

The new global catalog of craters for Mercury, containing morphological and morphometric information, includes data onthe location (latitude, longitude), diameter, depth and such features of craters as the degree of preservation of the rampart,the presence of terraces and collapses on the inner slope, the presence of peaks, hills and ridges, cracks...

Radar observations of the surface of Mercury had revealed areas with bright reflective properties in both polar regions of the planet. It was suggested that such areas contain depositions of volatile compounds, including water. In this paper, we investigated migration of water molecules to the permanently shaded areas, located in the impact crater...

We present a study on the relationship between the ratio of the depth of a crater to its diameter and the diameter for lunar craters both on the maria and on the highlands. We consider craters younger than 1.1 billion years in age, i.e. of Copernican period. The aim of this work is to improve our understanding of such relationships based on our new...

We compare the number of lunar craters larger than 15 km across and younger than 1.1 Ga to the estimates of the number of craters that could have been formed for 1.1 Ga if the number of near-Earth objects and their orbital elements during that time were close to the corresponding current values. The comparison was performed for craters over the ent...

Our basic assumption is that water ice might have been nearly uniformly distributed (as an admixture) in Bennu's interiors by the moment of its arrival to the present orbit. According to the results obtained by solving the one-dimensional equation (in the radial direction from the surface of the body), the existence of water ice in Bennu is possibl...

Analysis of observations of unique impact-produced flash near the lunar terminator was performed. Maximal brightness of detected thermal flash is 5.2–5.9m in R band, mass of impacted meteoroid is about 0.18–28 kg. Height of shadow in the place of meteoroid’s impact was only about 1 km, making it possible observations of impact-produced dust particl...

The article presents the results of astrophysical studies of the Moon’s reflected and intrinsic radiation. We studied the intensity of the Moon’s infrared radiation and, thus, carried out a detailed research of the brightness temperature of the Moon’s visible disc, estimated the thermal inertia of the coating substance by the rate of its surface co...

In this paper, we investigated the possibility of existence of the hydrogen-containing volatile compounds, similar to those found in the Cabeus crater, in the area of the proposed landing ellipses of the Luna-Glob mission. We found that the existence of water ice and other hydrogen-containing substances is possible only in the presence of a shieldi...

Currently, a number of areas in the southern polar region of the Moon has been selected as a proposed landing sites for the future lunar mission of the Luna-25. Nevertheless, in this paper we have examined some areas in the North Pole region of the Moon as possible landing sites for future lunar missions. For a research we have chosen some areas lo...

In this paper, we analyze the illumination conditions, the thermal regime, and the possibility of deposits of volatile compounds existing in the vicinity region (NSR S5 region) near the southern pole of the Moon. It has been found that there are no permanently shadowed zones near the Scott crater and the NSR S5 region, though the temperature condit...

Twelve areas in the southepole region of the Moon have been previously suggested as potential landing sites for the Luna-25 (Luna-Glob) mission. Cur-rently three sites have been chosen as the most suitable for landing: they include ellipses number 1, 4 and 6. We investigated the temperature regime in these selected landing sites and the thermal sta...

In this work we examine the lunar crater Boguslawsky as a typical region of the illuminated southern lunar highlands with regard to its temperature regime and the behavior of the depth of the water/hydroxyl-related spectral absorption band near 3 µm wavelength. For estimating the surface temperature, we compare two different methods, the first of w...

The report provides a data on the chemical composition of the lunar soil in the area of PKT (Procellarum KREEP Terrane). This area encompasses the main part of the "Marea" basaltic volcanism of the visible side of the Moon. KREEP in the name of Procellarum KREEP Terrane title (PKT) means potassium (K), rare earth elements (REE) and phosphorus (P)....

The six statistically most stable spots with the lowered neutron flow were revealed by the LEND neutron spectrometer installed on board the LRO spacecraft in the both lunar polar regions. Five spots are located near the South Pole of the Moon and one - near the North Pole. Only one of the above spots - NSR S5 (center coordinates ~ 83º S, 30º E) - i...

One of the projects called "Zvezda" was developed in 1963. The spacecraft weighing about 200 tons was drawn together on the Earth's orbit of the items displayed in three launches of rocket-carrier H-1 and "Soyuz" for making a soft landing without entering into lunar satellite orbit. Spacecraft "Soyuz" with a crew of 2 - 3 people in the final stages...

In 1946, there was created the Council of Chief Designers on rocket technology in the Soviet Union that was headed by Sergey Pavlovich Korolev. In order to implement manned missions and launching of automatical space stations Sergey Korolev deleloped series of perfect three and four stage delivery vehicles based on battle ballistic missile.

The present paper attempts to assess the characteristics of the impactor that formed the Shackleton crater, located at the south pole of the Moon.

Conclusions were drawn regarding the possible range of t...

The article describes the morphological features of the moon areas with anomalously high content of thorium. The areas with high content of thorium are located in vicinity of Maria of the Moon visage.

Influence of the meteoroid bombardment on properties of the lunar exosphere has been confirmed. Quick increase in the zenith column density of Na atoms above the lunar north pole on August 13, 2009 at 0–1 UT is detected and explained by numerous collisions of relatively small Perseid meteoroids (<1 kg) with the Moon during maximum of the Perseid me...

Neutron spectroscopy and NIR reflectance spectrospcopy consistently indicate hydroxyl in the Gay-Lussac N and NE LPDs at the surface and at up to 1 m depth.

Temperature regime at the LCROSS impact site is studied. All detected species in the Cabeus crater as well as CH 4 and CO clathrate hydrates except H 2, CO, and CH 4 are stable against evaporation at the LCROSS impact site. CO and CH 4 can be chemisorbed at the surface of the regolith particles and exist in the form of clathrate hydrates in the lun...

Quick increase of brightness of Na D1 and D2 lines in the lunar exosphere during maximum of Perseid 2009 meteor shower on August 13, 2009 at 0-1^h UT is detected and explained by collisions of Perseid meteoroids with the Moon. Total mass of impacted Perseid meteoroids is about 15 kg. Upper limits of intensities of Si, Al, Ca, Fe, Ti, Ba, Li, and Mn...

Quick variability of brightness of Na lines in the lunar exosphere during maximum of Perseid 2009 meteor shower is detected and explained by impacts of Perseid meteoroids at the level of 10-16 g cm-2 s-1. Non-detection of lines of atoms of Ca, Al, and Si is explained by formation of metal oxides and condensation of dust particles.

Areas of thermal stability of Ca, Mg, and Na deposits are estimated. Complex species NH_3, C_2H_4, CH_3OH, and CH_4 can be destroyed during meteoroid bombardment. Polar species with maximal content in the impact-produced cloud are proposed.

The chemical composition of gas-phase species released to the lunar exosphere during meteoroid impacts has been analyzed. Majority of impact-produced metal-containing molecules are destroyed by the solar photons because typical photolysis lifetimes are shorter than ballistic flight times. Energies of metal atoms produced via photolysis of its monox...

We investigated the distribution of the temperature and illumination in the South Pole region of the Moon with data obtained by LRO (LOLA) spacecraft.

In this work we used the laser altimeter data onboard the Japanese lunar orbiter KAGUYA (SELENE) to investigate the relief and illumination condition near both poles of the Moon for the diurnal variation in the altitude of the sun above the horizon.

Crater Cabeus has been chosen by NASA as a target for impact experiment of LCROSS mission. On the basis of topographical data from KAGUYA we made a topographical model of Cabeus, the illumination map for crater and investigate the temperature distribution in crater.

There are several types of data being used for lunar DEM creation and mapping.

Using the two-layer model we calculate the diurnal variance of subsurface temperatures on the depth at the different thickness of regolith layer. The calculations demonstrate that the water ice deposits can exist in such conditions during geological time.

The maps of density distribution of craters with different degree of rim degradation were compiled with use of Morphological catalogue of Mercurian craters created in Sternberg State Astronomical Institute on the base of Mariner 10 data. Coordinates of craters in the catalogue are changed in accordance with new data of Mercury North Pole. A treatme...

We have allocated a number of craters which can be considered as "cold traps " in the south pole region of the Moon. Some from these craters has properties similar to those of the echo coming from icy satellites of Jupiter and from the southern polar cap of Mars.

Craters located in the polar regions of Mercury and the Moon are studied. The areas of permanently shadowed zones in the polar regions of both celestial bodies are computed. In the case of the Moon, variations of the position of its rotation pole with respect to the ecliptic pole during the 18.6-year period were taken into account. In the case of M...

Among craters of Mercury investigated here, possessing abnormal reflective properties, craters D, W, E, F, X and G can except water ice, uncovered a layer of regolith, and other volatiles connections, such as CO_2 and NH_3 (except for crater G).

We investigated distribution of constantly shaded areas in polar craters of the Moon and connection o f these areas with areas of the enhanced hydrogen, revealed by Lunar Prospector. The changes of temperature inside such craters have been designed. We took into account change the heat flow from the Sun depending on position the line of nodes of th...

We are compiling an atlas of the presently available data products pertinent to the Beagle-2 landing site at 11.6N 90.75E, which is intended for distribution both as a printed and an electronic resource.

We numerically calculate the probability and area of permanent shadowing as a function of the selenographic latitude as well as the total area of the permanently shadowed surface for various hierarchical models of the lunar surface. The permanently shadowed area is shown to rapidly increase with increasing number of hierarchical surface levels. For...

Morphological catalogue of the MoonSs craters prepared by Lunar and Planetary Department of Sternberg Institute was used to study illumination of craters situated near lunar poles.
