Q: Information: - A robotic spacecraft is an uncrewed spacecraft, usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. - The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991. A union of multiple subnational republics, its government and economy were highly centralized. The Soviet Union was a one-party federation, governed by the Communist Party with Moscow as its capital. - Luna 15 was an unmanned space mission of the Soviet Luna programme . On 21 July 1969 , while Apollo 11 astronauts finished the first human moonwalk , Luna 15 , an unmanned Soviet spacecraft in lunar orbit at the time , began its descent to the lunar surface . Launched three days before the Apollo 11 mission , it was the second Soviet attempt to return lunar soil back to Earth with a goal to outstrip the US in sample return under Moon race . The Soviet craft crashed into the Moon at 15:50 UT , hours before the scheduled American lift off from the Moon . - An orbiter is a space probe that orbits a planet or other astronomical object. An orbiter can be either man-made, or created naturally. - In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: - The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary). Following Jupiter's satellite Io, the Moon is second-densest satellite among those whose densities are known. - Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or "gravitate" toward) one another, including planets, stars and galaxies. Since energy and mass are equivalent, all forms of energy, including light, also cause gravitation and are under the influence of it. On Earth, gravity gives weight to physical objects and causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars and the stars to group together into galaxies so gravity is responsible for many of the large scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects. - The Luna programme (from the Russian word "Luna" meaning "Moon"), occasionally called "Lunik" or "Lunnik" by western media, was a series of robotic spacecraft missions sent to the Moon by the Soviet Union between 1959 and 1976. Fifteen were successful, each designed as either an orbiter or lander, and accomplished many firsts in space exploration. They also performed many experiments, studying the Moon's chemical composition, gravity, temperature, and radiation. - A temperature is an objective comparative measurement of hot or cold. It is measured by a thermometer. Several scales and units exist for measuring temperature, the most common being Celsius (denoted C; formerly called "centigrade"), Fahrenheit (denoted F), and, especially in science, Kelvin (denoted K).

Question: Information: - The PlayStation Portable (PSP) is a handheld game console developed by Sony. Development of the console was announced during E3 2003, and it was unveiled on , 2004, at a Sony press conference before E32004. The system was released in Japan on , 2004, in North America on , 2005, and in the PAL region on , 2005. It primarily competed with the Nintendo DS, as part of the seventh generation of video games. - Downloadable content (DLC) is additional content created for a released video game. It is distributed through the Internet by the game's official publisher. Downloadable content can be of several types, ranging from aesthetic outfit changes to a new, extensive storyline, similar to an expansion pack. As such, DLC may add new game modes, objects, levels, challenges or other features to a complete, already released game. - The PlayStation Store (also abbreviated as PSN Store) is a digital media store available to users of Sony's PlayStation 3, PlayStation 4, PlayStation Vita and PlayStation Portable game consoles via the PlayStation Network. The store offers a range of downloadable content both for purchase and available free of charge. Available content includes full games, add-on content, playable demos, themes and game/movie trailers. - Elefunk is a downloadable game on the PlayStation Store . - The PlayStation 3 (abbreviated as PS3) is a home video game console developed by Sony Computer Entertainment. It is the successor to PlayStation 2, and is part of the PlayStation brand of consoles. It competed with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles. It was first released on November 11, 2006, in Japan, November 17, 2006 in North America, and March 27, 2007 in Europe and Australia. - Digital media is any media that is encoded in a machine-readable format. Digital media can be created, viewed, distributed, modified and preserved on digital electronics devices. Computer programs and software; digital imagery, digital video; video games; web pages and websites, including social media; data and databases; digital audio, such as mp3s; and e-books are examples of digital media. Digital media are frequently contrasted with print media, such as printed books, newspapers and magazines, and other traditional or analog media, such as pictures, film or audio tape. - PlayStation Network (PSN) is a digital media entertainment service provided by Sony Interactive Entertainment. Launched in November 2006, PSN was originally conceived for the PlayStation video game consoles, but soon extended to encompass smartphones, tablets, Blu-ray players and high-definition televisions. As of April 2016, over 110 million users have been documented, with 65 million of them active monthly.
