Smart Lander For Investigating Moon
Smart Lander for Investigating Moon (SLIM) is a lunar lander being developed by the Japan Aerospace Exploration Agency (JAXA). The lander will demonstrate precision landing technology. By 2017, the lander was planned to be launched in 2021, but this has been subsequently delayed to 2023 due to delays in SLIM's rideshare mission, X-Ray Imaging and Spectroscopy Mission (XRISM). Overview SLIM will be Japan's first lunar surface mission, and will demonstrate precise, pinpoint lunar landing. During its descent to the Moon, the lander will recognize lunar craters by applying technology from facial recognition systems, and determine its current location from utilizing observation data collected by the SELENE (Kaguya) lunar orbiter mission. SLIM aims to soft land with an accuracy range of . In comparison, the accuracy of the Apollo 11 Eagle lunar module was an elliptic which was wide in downrange and wide in crossrange. According to Yoshifumi Inatani, deputy director general of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lander (spacecraft)
A lander is a spacecraft that descends towards, comes to rest on, the surface of an astronomical body. In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional. For bodies with atmospheres, the landing occurs after atmospheric entry. In these cases, landers may employ parachutes to slow them down enough to maintain a low terminal velocity. In some cases, small landing rockets will be fired just before impact in order to reduce the lander's velocity. Landing may be accomplished by controlled descent and set down on landing gear, with the possible addition of a post-landing attachment mechanism (such as the mechanism used by ''Philae'') for celestial bodies with low gravity. Some missions (for example, Luna 9 and Mars Pathfinder) used inflatable airbags to cushion the lander's impact rather than utilizing more traditional landing gear. When a hi ...

Landing Ellipse
A landing footprint, also called a landing ellipse, is the area of uncertainty of a spacecraft's landing zone on an astronomical body. After atmospheric entry, a non-powered spacecraft will land in an area depending upon entry angle, entry mass, atmosphere and drag. It is therefore impossible to know the spacecraft's landing point with absolute precision. By simulating varying reentry courses, a numerical simulation will produce a plot resembling a footprint. The footprint size depends on the confidence interval In frequentist statistics, a confidence interval (CI) is a range of estimates for an unknown parameter. A confidence interval is computed at a designated ''confidence level''; the 95% confidence level is most common, but other levels, such as 9 ... used to develop the map.

Space Launch System
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle developed by NASA. As of 2022, SLS has the highest payload capacity of any rocket in operational service, as well as the greatest liftoff thrust of any rocket in operation. As the primary launch vehicle of the Artemis moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first uncrewed launch, Artemis 1, took place on 16 November 2022. Development of SLS began in 2011, as a replacement for the retired Space Shuttle as well as the cancelled Ares I and Ares V launch vehicles. As a Shuttle-derived vehicle, the Space Launch System reuses hardware from the Space Shuttle program, including the Space Shuttle Solid Rocket Booster, solid rocket boosters and RS-25, RS-25 first stage engines. An original flight date of late 2016 was delayed by nearly 6 years. The SLS program has Space Launch System#Criticism, attracted criticism for such de ...

CubeSat
A CubeSat is a class of miniaturized satellite based around a form factor consisting of cubes. CubeSats have a mass of no more than per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. , more than 1,600 CubeSats have been launched. In 1999, California Polytechnic State University (Cal Poly) professor Jordi Puig-Suari and Bob Twiggs, a professor at Stanford University Space Systems Development Laboratory, developed the CubeSat specifications to promote and develop the skills necessary for the design, manufacture, and testing of small satellites intended for low Earth orbit (LEO) that perform a number of scientific research functions and explore new space technologies. Academia accounted for the majority of CubeSat launches until 2013, when more than half of launches were for non-academic purposes, ...

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. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

DESTINY+
Destiny, sometimes referred to as fate (from Latin ''fatum'' "decree, prediction, destiny, fate"), is a predetermined course of events. It may be conceived as a predetermined future, whether in general or of an individual. Fate Although often used interchangeably, the words ''fate'' and ''destiny'' have distinct connotations. *Traditional usage defines fate as a power or agency that predetermines and orders the course of events. Fate defines events as ordered or "inevitable" and unavoidable. This is a concept based on the belief that there is a fixed natural order to the universe, and in some conceptions, the cosmos. Classical and European mythology feature personified "fate spinners," known as the Moirai in Greek mythology, the Parcae in Roman mythology, and the Norns in Norse mythology. They determine the events of the world through the mystic spinning of threads that represent individual human fates. Fate is often conceived as being divinely inspired. *Fate is about the ...

Tomy
is a Japanese entertainment company that makes children's toys and merchandise. It was created from a merger on March 1st 2006 of two companies: Tomy (founded in 1924 as Tomiyama, changing the name to Tomy in 1963) and long-time rival Takara (founded in 1955). The company has its headquarters in Katsushika, Tokyo. History and corporate name Before the merger The company was named Tomy as an abridgement of Tomiyama, which was the founder's surname. Starting as a manufacturer, Tomy had the largest product development team in the toy industry and plaudits for its technology. Nonetheless, by its third generation, president Mikitaro Tomiyama decided to streamline the company to be more competitive with wholesaler Bandai. Bandai developed its products more quickly, which was more appealing to television properties that required a fast turnaround. Despite internal and external opposition, Tomiyama was determined to aggressively pursue TV licenses such as Akakage, Giant Robo a ...

Lunar Lava Tube
Lunar lava tubes are lava tubes on the Moon formed during the eruption of basaltic lava flows. When the surface of a lava flow cools, it hardens and the lava can channel beneath the surface in a tube-shaped passage. Once the flow of lava diminishes, the tube may drain, forming a hollow void. Lunar lava tubes are formed on sloped surfaces that range in angle from 0.4° to 6.5°. These tubes may be as wide as before they become unstable against gravitational collapse. However, stable tubes may still be disrupted by seismic events or meteoroid bombardment. The existence of a lava tube is sometimes revealed by the presence of a "skylight", a place in which the roof of the tube has collapsed, leaving a circular hole that can be observed by lunar orbiters. Observational evidence An area displaying a lava tube and rilles is the Marius Hills region (). In 2008, an opening to a lava tube in this area may have been discovered by the Japanese Kaguya spacecraft. The skylight was photograp ...
