Titius (crater)
Titius is a lunar impact crater that is located on the Moon's far side, beyond the eastern limb. It lies to the west of the Lacus Solitudinis, a small lunar mare. Less than a crater diameter to the north east is the crater Bowditch, and farther to the southwest is Donner. The rim of this crater has been nearly ruined by subsequent impacts, leaving only the northern and northeast parts relatively intact. There is a breach in the rim to the south, with the southeast overlain by Titius J and the southwest by Titius N and Titius Q, leaving only a short length of shallow, surviving rim to the south-southwest. The western rim is disrupted by three other small craters. The interior floor has some irregularities, but is relatively featureless and level to the northeast. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Titius.

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to Moon landing, land on the Moon. It was the first List of Apollo missions#Alphabetical mission types, J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Apollo Commander, Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley–Apennine#Rima Hadley, Hadley Rille and explored the local area using the rover, allowing them to travel further from the Apollo Lunar Module, lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moo ...

Donner (crater)
Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surfa ..., but the site is viewed from the edge and so not much detail can be seen. This crater has a moderately eroded outer rim, and several small and tiny craterlets lie along the edge. A joined pair of small craters lie across the southern rim and inner wall. An unnamed, crater-like feature with about the same diameter as Donner is attached to the northern outer rim. The structure along the inner wall has been softened and rounded by a long history of minor impacts. The interior fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 campaigne ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station.

Bowditch (crater)
Bowditch is a Lunar craters, lunar impact crater that lies on the Far side (Moon), far side of the Moon, just beyond the eastern limb. It is located on a region of the lunar surface that is brought into view due to libration, but at such times the area is viewed from the edge and so not much detail can be observed. It lies just to the north of the small Lacus Solitudinis lunar mare, between the craters Titius (crater), Titius to the southwest and Perel'man (crater), Perel'man to the east-northeast. The rim of this crater is open to the southwest and the crater is elongated to the northeast, possibly due to a merged crater. The outer rim varies in height, with the most prominent sections being the southwest face and a ridge mount to the northwest. The interior floor has been flooded with basaltic lava, an unusual feature for a crater on the far side. The interior floor is generally flat, and marked by a number of small craters. However, there are some low ridges in the surface that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lunar Mare
The lunar maria (; singular: mare ) are large, dark, basaltic plains on Earth's Moon, formed by ancient asteroid impacts on the far side on the Moon that triggered volcanic activity on the opposite (near) side. They were dubbed , Latin for 'seas', by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one (ocean), as well as features with the names ('lake'), ('marsh'), and ('bay'). The last three are smaller than maria, but have the same nature and characteristics. The names of maria refer to sea features (Mare Humorum, Mare Imbrium, Mare Insularum, Mare Nubium, Mare Spumans, Mare Undarum, Mare Vaporum, Oceanus Procellarum ...

Lacus Solitudinis
Lacus Solitudinis (Latin ''sōlitūdinis'', "Lake of Solitude") is a small lunar mare on the far side of the Moon. The selenographic coordinates of the lake are 27.8° S, 104.3° E, and it lies within a diameter of 139 km. It forms an arcing feature with the concave side oriented to the northwest. The eastern edge is relatively continuous, while the west is more irregular and disrupted by small craters. To the northwest of the northern end is the small crater Bowditch, a lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or un ...-flooded feature although it does not appear directly connected to the Lacus Solitudinis. At the western end of the mare, the eroded crater Titius lies to the northwest. To the south of this feature is Parkhurst Y, with Parkhurst itself lying some ...
