Solis Lacus
Solis Lacus (), (Latin, "lake of the sun") is a dark feature on Mars. It was once called "Oculus" and is still commonly called "The Eye of Mars" because with the surrounding light area called Thaumasia it resembles the pupil of one. Solis Lacus is known for the variability of its appearance, changing its size and shape when dust storms occur. Percival Lowell believed that it was the planetary capital of Mars due to the number of canals he claimed intersected at the region. In Science fiction In ''The Lost Worlds of 2001'', Arthur C. Clarke had it as the landing site of the first robotic probe to Mars. In Robert Heinlein's ''Stranger in a Strange Land,'' the crewed exploratory vessel ''Envoy'' lands just south of Solis Lacus. In Larry Niven's Known Space universe, Solis Lacus was the site of an early human base which was destroyed by the native Martians, and later featured in his novel, Protector Protector(s) or The Protector(s) may refer to: Roles and titles * Protector ...

Mars Solis Lacus
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period and tilt o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thaumasia Quadrangle
The Thaumasia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Thaumasia quadrangle is also referred to as MC-25 (Mars Chart-25). The name comes from Thaumas, the god of the clouds and celestial apparitions. The Thaumasia quadrangle covers the area from 60° to 120° west longitude and 30° to 65° south latitude on Mars. The Thaumasia quadrangle contains many different regions or parts of many regions: Solis Planum, Icaria Planum, Aonia Terra, Aonia Planum, Bosporus Planum, and Thaumasia Planum. One of the first major networks of stream channels, called Warrego Valles, were discovered here by early orbiters. Another sign of water is the presence of gullies carved into steep slopes. Martian Gullies Gullies are common in some parts of Mars. Gullies occur on steep slopes, especially on the walls of craters. Martian gullies are believed to be relatively young because they have few, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percival Lowell
Percival Lowell (; March 13, 1855 – November 12, 1916) was an American businessman, author, mathematician, and astronomer who fueled speculation that there were canals on Mars, and furthered theories of a ninth planet within the Solar System. He founded the Lowell Observatory in Flagstaff, Arizona, and formed the beginning of the effort that led to the discovery of Pluto 14 years after his death. Life and career Early life and work Percival Lowell was born on March 13, 1855, in Boston, Massachusetts, the first son of Augustus Lowell and Katherine Bigelow Lowell. A member of the Brahmin Lowell family, his siblings included the poet Amy Lowell, the educator and legal scholar Abbott Lawrence Lowell, and Elizabeth Lowell Putnam, an early activist for prenatal care. They were the great-grandchildren of John Lowell and, on their mother's side, the grandchildren of Abbott Lawrence. Percival graduated from the Noble and Greenough School in 1872 and Harvard University in 1876 with d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martian Canals
During the late 19th and early 20th centuries, it was erroneously believed that there were "canals" on the planet Mars. These were a network of long straight lines in the equatorial regions from 60° north to 60° south latitude on Mars, observed by astronomers using early telescopes without photography. They were first described by the Italian astronomer Giovanni Schiaparelli during the opposition of 1877, and confirmed by later observers. Schiaparelli called these ''canali'' ("channels"), which was mis-translated into English as "canals". The Irish astronomer Charles E. Burton made some of the earliest drawings of straight-line features on Mars, although his drawings did not match Schiaparelli's. Around the turn of the century there was even speculation that they were engineering works, irrigation canals constructed by a civilization of intelligent aliens indigenous to Mars. By the early 20th century, improved astronomical observations revealed the "canals" to be an optical illu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Lost Worlds Of 2001
''The Lost Worlds of 2001'' is a 1972 book by English writer Arthur C. Clarke, published as an accompaniment to the novel '' 2001: A Space Odyssey''. The book consists in part of behind-the-scenes notes from Clarke concerning scriptwriting (and rewriting), as well as production issues. The core of the book, however, comprises excerpts from the proto-novel and an early screenplay that did not make it into the final version. Alternative settings for launch preparation, the EVA scene where astronaut Frank Poole is lost, and varying dialogues concerning the HAL 9000 HAL 9000 is a fictional artificial intelligence character and the main antagonist in Arthur C. Clarke's ''Space Odyssey'' series.

Arthur C
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Robert Heinlein
Robert Anson Heinlein (; July 7, 1907 – May 8, 1988) was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers", he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally. Heinlein became one of the first American science-fiction writers to break into mainstream magazines such as ''The Saturday Evening Post'' in the late 1940s. He was one of the best-selling science-fiction novelists for many decades, and he, Isaac Asimov, and Arthur C. Clarke are often considered the "Big Three" of English-language sci ...

Stranger In A Strange Land
''Stranger in a Strange Land'' is a 1961 science fiction novel by American author Robert A. Heinlein. It tells the story of Valentine Michael Smith, a human who comes to Earth in early adulthood after being born on the planet Mars and raised by Martians, and explores his interaction with and eventual transformation of Terran culture. The title "Stranger in a Strange Land" is a direct quotation from the King James Bible (taken from Exodus 2:22). The working title for the book was "A Martian Named Smith", which was also the name of the screenplay started by a character at the end of the novel. Heinlein's widow Virginia arranged to have the original unedited manuscript published in 1991, three years after Heinlein's death. Critics disagree about which version is superior. ''Stranger in a Strange Land'' won the 1962 Hugo Award for Best Novel and became the first science fiction novel to enter ''The New York Times Book Review'''s best-seller list. In 2012, the Library of Congress n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Known Space
Known Space is the fictional setting of about a dozen science fiction novels and several collections of short stories written by Larry Niven. It has also become a shared universe in the spin-off ''Man-Kzin Wars'' anthologies. The Internet Speculative Fiction Database (ISFDB) catalogs all works set in the fictional universe that includes Known Space under the series name Tales of Known Space, which was the title of a 1975 collection of Niven's short stories. The first-published work in the series, which was Niven's first published piece was "The Coldest Place", in the December 1964 issue of '' If'' magazine, edited by Frederik Pohl. This was the first-published work in the 1975 collection. The stories span approximately one thousand years of future history, from the first human explorations of the Solar System to the colonization of dozens of nearby systems. Late in the series, Known Space is an irregularly shaped "bubble" about 60 light-years across. The epithet "Known Space" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protector (novel)
''Protector'' is a 1973 science fiction novel by American writer Larry Niven, set in his Known Space universe. It was nominated for the Hugo in 1974, and placed fourth in the annual Locus poll for that year. The work fleshes out a species called the Pak, originally introduced in a 1967 story called "The Adults", which forms the first half of the novel (there titled ''Phssthpok''); the second half is titled ''Vandervecken''. The Pak also appear in several of Niven's later works, including the later volumes of the ''Ringworld'' series and the novel '' Destroyer of Worlds'' which serves as a semi-sequel to ''Protector''. Plot summary The novel comprises two phases in the same space that are separated by 220 years of time. Its central conceit is that Humans evolved from the juvenile stage of the Pak, a species with a distinct adult form ("Protectors") that has immense strength and intelligence and cares only about younger Pak of their bloodline. A key plot point is that transit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
