Curie (lunar Crater)
Curie is a large lunar impact crater, much of which lies on the far side of the Moon as seen from the Earth. The western rim projects into the near side of the Moon, as defined by the selenographic coordinate system. However the visibility of this formation depends on the effects of libration, so that it can be brought fully into view or completely hidden depending on the orientation of the Moon. When visible, however, it is seen nearly from the side, limiting the amount of detail that can be observed. Nearby craters of note include Schorr Schorr ( he, שור) is a surname. Notable people with the surname include: * Avraham Schorr, American rabbi * Bill Schorr, American cartoonist * Daniel Schorr (1916–2010), American journalist * Friedrich Schorr (1888–1953), Hungarian-Austrian o ... to the northwest and the walled plain Sklodowska to the northeast.

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first 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. Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the 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 Moon, operating the sensors in the scientific instrument module (SIM) bay of the service module. This suite of instruments co ...

Schorr (crater)
Schorr is a lunar impact crater that lies across the eastern limb of the Moon. From the Earth this crater is viewed from the side, limiting the amount of detail that can be observed. The visibility of this crater is also affected by libration of the Moon in its orbit. The crater lies just to the northwest of the walled plain Curie, and to the east-southeast of the crater Gibbs. When viewed from orbit, this appears as a circular crater with an outer rim that has not been significantly worn through impact erosion. The material along the inner walls has accumulated along the bottom of the sloping sides, forming a ledge along parts of the base. The interior floor is irregular in places, with low ridges crossing parts of the bottom. Schorr intrudes slightly into the satellite crater Schorr A to the southeast. 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 Schorr. See also * ...

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 campaig ...

Lauritsen (crater)
Lauritsen is a lunar impact crater that is located just behind the east-southeastern limb of the Moon. It is named for physicist Charles Christian Lauritsen. While it lies on the far side from the Earth, it is still possible to catch a glimpse of this area under favorable conditions of libration In lunar astronomy, libration is the wagging or wavering of the Moon perceived by Earth-bound observers and caused by changes in their perspective. It permits an observer to see slightly different hemispheres of the surface at different tim ... and illumination. The crater is situated roughly equidistant from Titius to the east and Donner to the southeast, so that the three form an equilateral triangle. To the northwest is the walled plain Curie. This is an eroded crater with an eastern rim that is almost completely overlain by smaller craters, including Lauritsen B along the northeast. There is a break in the rim to the north and a pair of small craters lies across the northwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sklodowska (lunar Crater)
Sklodowska (Skłodowska) is a large lunar impact crater that is located on the far side of the Moon. It lies just past the southeastern limb, and can sometimes be viewed from Earth under favorable conditions of libration and illumination. The crater is located to the northeast of the older walled plain Curie, and to the southwest of Pasteur, another walled plain. This is a prominent crater with a well-defined rim and little appearance of wear from impact erosion. The edge forms a rough circle, but it is irregular with a number of small outward bulges, particularly to the south and southwest. The small crater Sklodowska J intrudes slightly into the southeastern rim. The inner walls have a system of multiple terraces, and there are some slumped shelves along the northeastern side. The inner wall is somewhat narrower along the north and wider to the south and northeast. Within the crater the interior floor is a nearly level plain that is marked by a number of small craterlets. There ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libration
In lunar astronomy, libration is the wagging or wavering of the Moon perceived by Earth-bound observers and caused by changes in their perspective. It permits an observer to see slightly different hemispheres of the surface at different times. It is similar in both cause and effect to the changes in the Moon's apparent size due to changes in distance. It is caused by three mechanisms detailed below, two of which cause a relatively tiny physical libration via tidal forces exerted by the Earth. Such true librations are known as well for other moons with locked rotation. The quite different phenomenon of a trojan asteroid's movement has been called ''Trojan libration''; and ''Trojan libration point'' means Lagrangian point. Lunar libration The Moon keeps one hemisphere of itself facing the Earth, due to tidal locking. Therefore, the first view of the far side of the Moon was not possible until the Soviet probe Luna 3 reached the Moon on October 7, 1959, and further lunar ...

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 surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
