In general, Pluto's north polar region is a deeply fractured and eroded dome 2–3 kilometers high (– miles high). The 3-kilometer-deep (mile-deep) Sputnik Planitia impact basin (blue at top) is partially filled by a vast nitrogen and methane ice sheet. Even so, the north polar region needs further analysis before NASA can decide where to go first. Clementine was in a position to see the lunar north pole for .
The elliptical, polar orbit of NASA’s Lunar Reconnaissance Orbiter (LRO) is closest to the Moon during its pass over the South Pole region. Through its thousands of orbits in the last decade, LRO has collected the most precise information about the South Pole region than any other, offering scientists precise details about its topography. Chandrayaan 2 is a highly complex mission comprises of orbiter, lander, and a rover to explore the south polar region of the Moon which is not explored by any other space organization.

polar regions. Although this technique has the potential to map the topography of the whole lunar near side at this reso- lution, radar can reach neither the far side of the lunar polar regions beyond the +7 ø limits of libration in the latitudinal direction [Heiken et al., ] nor the near-side limb areas obscured by local topography. At the lunar terminator and polar regions, the solar wind bulk ion flow is primarily horizontal over the lunar surface. Local topography then acts to block or obstruct the plasma as it flows – creating voids in the solar wind fluid immediately downstream of the obsta-cle (south polar mountain or crater).

Topography and Permanently Shaded Regions (PSRs) of the Moon’s South Pole (80°S to Pole) This map is based on data released by the Lunar Reconnaissance Orbiter Lunar Orbiter Laser Altimeter (LOLA). The map is centered on the south pole and shows the LOLA m elevation product between 80°S and the pole (NASA Goddard Space Flight Center; Smith et al., ; Smith et al., ).
Long and short wavelength topography in the vicinity of the pole, in combination with measurements of depths of well‐preserved craters and basins and the lunar topographic power spectrum, have direct bearing on the nature of elevations in the south polar by: To assist NASA and the lunar community, LPI/USRA have compiled an online atlas that consists of a series of maps, images, and illustrations of the south polar region.
New data products are developed with the south pole directive in mind; other content is drawn from LPI’s existing collection of Lunar Images and Maps and its Library of.
The lunar south pole is of special interest to scientists because of the occurrence of water ice in permanently shadowed areas around it. The lunar south pole region features craters that are unique in that the near-constant sunlight does not reach their interior.
Such craters are cold traps that contain a fossil record of hydrogen, water ice, and other volatiles dating from the early Solar. We analyze Clementine altimetry to constrain the size and location of proposed permanently shadowed regions in the vicinity of the lunar south pole.

These include: long wavelength lunar topography, near-polar short wavelength topography, measured depths of craters and basins distributed over the lunar surface, and the global topographic power spectrum.

Long simulations (several decades) are used to obtain average illumination maps. Permanently shadowed regions and sites of maximum illumination are characterized. We assess the single-scattering environment in those permanently shadowed regions.
Small height gains above the surface can. Topographic maps of the lunar polar regions (Figs. 1 and2) show that the north polar area displays relatively little topographic expression, whereas the south polar region presents much more rugged terrain.
The range of elevations characterizing the south polar region. This is in good agreement with results from the Diviner instrument (Paige et al., ), who found the LCROSS impact site to be one of the coldest locations in the south pole region for present lunar orientation.
In addition, Cabeus also has the highest hydrogen content in the south polar region (Mitrofanov et al., a, Mitrofanov et al., c). The topography of the Moon has been measured by the methods of laser altimetry and stereo image analysis, including data obtained during the Clementine most visible topographic feature is the giant far side South Pole-Aitken basin, which possesses the lowest elevations of the Moon.
The highest elevations are found just to the north-east of this basin, and it has been suggested that. We analyze Clementine altimetry to constrain the size and location of proposed permanently shadowed regions in the vicinity of the lunar south pole.

[Maria T Zuber; David E Smith; United States. National Aeronautics and Space Administration.]. The elliptical, polar orbit of NASA’s Lunar Reconnaissance Orbiter is closest to the Moon during its pass over the south pole region.
Through its thousands of orbits in the last decade, LRO has collected the most precise information about the south pole region than any other, offering scientists precise details about its topography. In order to better plan and determine the optimal landing sites for such probes, as much a priori information as possible on the lunar south polar region is desired.
Of particular importance from a landing survivability and accessible exploration region perspective is knowledge concerning the lunar topography. The large, roughly circular, low-lying area (deep blue and purple) is the South Pole—Aitken Basin, the largest and deepest impact feature on the Moon.
Lunar Topographic Map This remarkable map, created using WAC images and LOLA laser profiles, shows the highs and lows over nearly the entire Moon at a pixel scale of meters ( feet). Part of the Springer Proceedings in Advanced Robotics book series (SPAR, volume 5) Abstract. Sun-synchronous lunar polar exploration can extend solar-powered robotic missions by an order of magnitude by following routes of continuous sunlight.
However, enforcing an additional constraint for continuous Earth communication while driving puts such. Topographic maps of the lunar polar re-gions (Figs. 1 and 2) show that the north polar area displays relatively little topographic ex-pression, whereas the south polar region pre-sents much more rugged terrain.
The range of elevations characterizing the south polar re-gion is roughly times that at the north. The extent of permanent shadow. The Clementine spacecraft made the first near-global topographic map (referenced to a mean lunar radius of km) of the Moon from laser altimetry (LA).
Because the spacecraft was in an elliptical orbit and the laser ranger could not detect returns when the spacecraft was farther than km from the Moon, we do not possess ranging data for latitudes within 15 degrees of the poles.
The primary goal of the LOLA instrument onboard LRO was to map the topography of the Moon, but another important objective was to map the regions of permanent shadow.
This is best accomplished by modeling the illumination conditions of the entire lunar polar regions over long timescales. The Moon’s polar regions are notable because of their potential to cryogenically trap water ice and other volatile species ().The Lunar Reconnaissance Orbiter (LRO) Diviner Lunar Radiometer Experiment has been mapping the infrared emission from the Moon since July using seven spectral channels that span a wavelength range from to μm at a spatial resolution of.
1 day ago Permanently shadowed regions at the moon's poles have a story to tell. Sun-shy polar ice patches could not only yield an account of lunar history but also offer astrobiological clues regarding the.LRO launched on an Atlas V rocket on Jbeginning a four-day trip to the Moon. LRO spent its first three years in a low polar orbit collecting detailed information about the Moon and its environment.
After this initial orbit, LRO transitioned to a stable elliptical orbit, passing low over the lunar south pole.Color Shaded Relief Map of the Moon's South Polar Region Image Credit: A topographic map of the Moon's south pole and the Aitken basin, the largest observed impact structure on the Moon, based on data from NASA's Lunar Reconnaissance Orbiter.
