Bose (crater)
Bose is a lunar impact crater that is located on the far side of the Moon, in the southern sphere hemisphere. It lies just to the northwest of the smaller crater Bhabha, and southeast of Alder. The outer rim of Bose has become worn and the edges rounded by impacts, although the shape of the wall is still well-preserved. The small satellite crater Bose D lies across the east-northeastern rim, and a smaller craterlet has impacted on the inner southeast wall. The inner floor is level with a low central peak offset slightly to the southeast of the midpoint. There are several tiny craterlets marking the interior, including three to the east of the central peak. The crater is named after an eminent Indian polymath, Sir Jagadish Chandra Bose, for his works on wireless communication. Satellite craters By convention these features are identified in selenography by placing the letter on the side of the crater midpoint that is closest to Bose.

Clementine (spacecraft)
''Clementine'' (officially called the Deep Space Program Science Experiment (DSPSE)) was a joint space project between the Ballistic Missile Defense Organization (previously the Strategic Defense Initiative Organization) and NASA, launched on January 25, 1994. Its objective was to test sensors and spacecraft components in long-term exposure to space and to make scientific observations of both the Moon and the near-Earth asteroid 1620 Geographos. Results Observation of the asteroid was not made due to a malfunction in the spacecraft. The lunar observations included imaging at various wavelengths in the visible as well as in ultraviolet and infrared, laser ranging altimetry, gravimetry, and charged particle measurements. These observations were for the purposes of obtaining multi-spectral imaging of the entire lunar surface, assessing the surface mineralogy of the Moon, obtaining altimetry from 60N to 60S latitude, and obtaining gravity data for the near side. There were al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alder (crater)
Alder is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It is located in the South Pole-Aitken basin, and lies to the southeast of the crater Von Kármán. Southeast of Alder is Bose, and to the south-southwest lies Boyle. The inner wall of Alder is rough and slightly terraced, with the material scattered across the edges of the otherwise relatively flat interior floor. There are several low central ridges lying along a band from the midpoint toward the eastern rim. A small crater lies on the eastern inner slopes. The crater is otherwise free of significant impacts within the rim. Alder is associated with the only area in the basin not dominated by the pyroxene rocks typical of lunar lowlands. This ''alder ejecta'' area is on spectrographic evidence instead principally anorthosite Anorthosite () is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–100%), with a mini ...

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age, hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally the website was hosted on a Harvard University account, but was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaign ...

Mitra (crater)
Mitra is a lunar impact crater that is attached to the western outer rim of the larger crater Mach, on the far side of the Moon. Just to the west of Mitra is Bredikhin, and to the south-southeast lies Henyey. It is named after Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan award recipient known for his pioneering work in the field of ionosphere and radiophysics. This is a heavily eroded formation with an outer rim that has been damaged by subsequent impacts. Attached to the exterior along the southeast is the satellite crater Mitra J. A number of smaller impacts lie along the rim edge, and very little of the original rim remains intact. Within the interior, a smaller crater occupies the southwestern part of the floor, and a small, cup-shaped crater lies across the northeast rim of this formation and very close to the midpoint of Mitra. The remaining floor is marked only by a few small and tiny craterlets. Mitra lies within the Dirichlet–Jackson Basin The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selenography
Selenography is the study of the surface and physical features of the Moon (also known as geography of the Moon, or selenodesy). Like geography and areography, selenography is a subdiscipline within the field of planetary science. Historically, the principal concern of selenographists was the mapping and naming of the lunar terrane identifying maria, craters, mountain ranges, and other various features. This task was largely finished when high resolution images of the near and far sides of the Moon were obtained by orbiting spacecraft during the early space era. Nevertheless, some regions of the Moon remain poorly imaged (especially near the poles) and the exact locations of many features (like crater depths) are uncertain by several kilometers. Today, selenography is considered to be a subdiscipline of selenology, which itself is most often referred to as simply "lunar science." The word selenography is derived from the Greek lunar deity Σελήνη ''Selene'' and γ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bhabha (crater)
Bhabha is a lunar impact crater that is located in the southern part of the Moon's far side. It is nearly attached to the southeast rim of the larger crater Bose, and the outer rampart of that crater has produced a slight inward bulge along the northwest face of Bhabha. Other nearby craters of note include Stoney to the east, and Bellinsgauzen to the south. This is a relatively fresh crater with a nicely terraced inner wall. This terracing is most notable along the southeastern half of the crater, and nearly disappears along the north-northwest rim where the inner wall is at its minimum extent. The rim and inner wall have not been significantly eroded, and there are no craterlets of note along the rim. The interior floor has a formation of central peaks that forms a semicircle with the concave interior open to the north. The remainder of the floor is relatively level, with a single small craterlet in the northern part. Bhabha was named in honor of the physicist Homi Jehang ...

Jagadish Chandra Bose
Sir Jagadish Chandra Bose (;, ; 30 November 1858 – 23 November 1937) was a biologist, physicist, botanist and an early writer of science fiction. He was a pioneer in the investigation of radio microwave optics, made significant contributions to botany, and was a major force behind the expansion of experimental science on the Indian subcontinent. Bose is considered the father of Bengali science fiction. He invented the crescograph, a device for measuring the growth of plants. A crater on the moon was named in his honour. He founded Bose Institute, a premier research institute in India and also one of its oldest. Established in 1917, the institute was the first interdisciplinary research centre in Asia. He served as the Director of Bose Institute from its inception until his death. Born in Munshiganj, Bengal Presidency, during British governance of India (now in Bangladesh), Bose graduated from St. Xavier's College, Calcutta (now Kolkata, West Bengal, India). He attended t ...

Sphere Hemisphere
A sphere () is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the centre of the sphere, and is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubbles such as soap bubbles take a spherical shape in equilibrium. The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres roll smoothly in any direction, so most balls used in sports and toys are spherical, as are ball bearings. Basic terminology As mentioned earlier is the sphere's ...
