The Man Who Sold The Moon
"The Man Who Sold the Moon" is a science fiction novella by American author Robert A. Heinlein, written in 1949 and published in 1950. A part of his ''Future History'' and prequel to "Requiem", it covers events around a fictional first Moon landing in 1978 and the schemes of Delos D. Harriman, a businessman who is determined to personally reach and control the Moon. Plot Delos David "D. D." Harriman, "the last of the Robber Barons", is obsessed with being the first to travel to—and possess—the Moon. He asks his business partner, George Strong, and other tycoons to invest in the venture. Most dismiss Harriman's plans as foolhardy: Nuclear rocket fuel is scarce as the space station that produces it blew up, also destroying the only existing spaceship. The necessary technology for a chemical-fueled rocket stretches the boundaries of current engineering. The endeavor is both incredibly costly and of uncertain profitability. One skeptic offers to sell "all of my interes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardcover
A hardcover, hard cover, or hardback (also known as hardbound, and sometimes as case-bound) book is one bound with rigid protective covers (typically of binder's board or heavy paperboard covered with buckram or other cloth, heavy paper, or occasionally leather). It has a flexible, sewn spine which allows the book to lie flat on a surface when opened. Modern hardcovers may have the pages glued onto the spine in much the same way as paperbacks. Following the ISBN sequence numbers, books of this type may be identified by the abbreviation Hbk. Hardcover books are often printed on acid-free paper, and they are much more durable than paperbacks, which have flexible, easily damaged paper covers. Hardcover books are marginally more costly to manufacture. Hardcovers are frequently protected by artistic dust jackets, but a "jacketless" alternative has increased in popularity: these "paper-over-board" or "jacketless" hardcover bindings forgo the dust jacket in favor of printing the cove ...

Cuius Est Solum Eius Est Usque Ad Coelum Et Ad Inferos
''Cuius est solum, eius est usque ad coelum et ad inferos'' (Latin for "whoever's is the soil, it is theirs all the way to Heaven and all the way to Hell") is a principle of property law, stating that property holders have rights not only to the plot of land itself, but also the air above and (in the broader formulation) the ground below. The principle is often referred to in its abbreviated form as the ''ad coelum'' doctrine. In modern law, this principle is still accepted in limited form; the rights are divided into air rights above and subsurface rights below. Property title includes to the space immediately above and below the ground – preventing overhanging parts of neighboring buildings – but do not have rights to control flights far above the ground or in space. In dense urban areas, air rights may be transferable (see transferable development rights) to allow construction of new buildings over existing buildings. In some jurisdictions, the ability to exploit minera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Promised Land
The Promised Land ( he, הארץ המובטחת, translit.: ''ha'aretz hamuvtakhat''; ar, أرض الميعاد, translit.: ''ard al-mi'ad; also known as "The Land of Milk and Honey"'') is the land which, according to the Tanakh (the Hebrew Bible or the Old Testament), God promised and subsequently gave to Abraham and several more times to his descendants. In modern contexts, the phrase "Promised Land" expresses an image and an idea which is related to the restored homeland for the Jewish people and the concepts of salvation and liberation. Divine promise The concept of the Promised Land is based on verses in the Tanakh (the Hebrew Bible or the Old Testament), in which God speaks to Abraham. The promises given to Abraham happened prior to the birth of Isaac and were given to all his offspring signified through the rite of circumcision. Johann Friedrich Karl Keil is less clear, as he states that the covenant is through Isaac, but notes that Ishmael's descendants have he ...

Lunar Colony
Colonization of the Moon or Lunar settlement is a process, or concept employed by some proposals, for claiming robotic or human exploitation and settlement on the Moon. Laying claim to the Moon has been declared illegal through international space law and no state has made such claims, despite having a range of probes and artificial remains on the Moon. While a range of proposals for missions of lunar colonization, exploitation or permanent exploration have been raised, current projects for establishing permanent crewed presence on the Moon are not for colonizing the Moon, but rather focus on building moonbases for exploration and to a lesser extent for exploitation of lunar resources. The commercialization of the Moon is a contentious issue for national and international lunar regulation and laws (such as the Moon treaty). History Colonization of the Moon has been imagined as early as the first half of the 17th century by John Wilkins in ''A Discourse Concerning a New Pla ...

Pikes Peak
Pikes Peak is the List of mountain ranges of Colorado#Mountain ranges, highest summit of the southern Front Range of the Rocky Mountains, in North America. The Ultra-prominent peak, ultra-prominent fourteener is located in Pike National Forest, west of downtown Colorado Springs, Colorado. The town of Manitou Springs, Colorado, Manitou Springs lies at its base. The mountain is named in honor of American explorer Zebulon Pike (though he was unable to reach the summit). The summit is higher than any point in the United States east of its longitude. Name The band of Ute people who called the Pikes Peak region their home were the Tabeguache, whose name means the "People of Sun Mountain". or "sun", is the Ute language, Ute word that was given by these first people to the mountain that we now call Pikes Peak. It is thought that the Ute people first arrived in Colorado about 500 A.D., however their oral history states that they were created on Tava. In the 1800s, when the Arapa ...

Mass Driver
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to Acceleration, accelerate and catapult Payload (air and space craft), payloads up to high speeds. Existing and contemplated mass drivers use coils of wire energized by electricity to make electromagnets, though a rotary mass driver has also been proposed. Sequential firing of a row of electromagnets accelerates the payload along a path. After leaving the path, the payload continues to move due to momentum. Although any device used to propel a Ballistics, ballistic payload is technically a mass driver, in this context a mass driver is essentially a coilgun that magnetically accelerates a package consisting of a magnetizable holder containing a payload. Once the payload has been accelerated, the two separate, and the holder is slowed and recycled for another payload. Mass drivers can be used to propel spacecraft in three different ways: A large, ground-based mas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multistage Rocket
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final speed and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subseq ...

Cancellation (mail)
A cancellation (or cancel for short; French: ) is a postal marking applied on a postage stamp or postal stationery to deface the stamp and to prevent its reuse. Cancellations come in a huge variety of designs, shapes, sizes, and colors. Modern cancellations commonly include the date and post office location where the stamps were mailed, in addition to lines or bars designed to cover the stamp itself. The term "postmark" refers specifically to the part that contains the date and posting location, but the term is often used interchangeably with "cancellation" as it may serve that purpose. The portion of a cancellation that is designed to deface the stamp and does not contain writing is also called the "obliteration" Scott US p. 30A. or killer. Some stamps are issued pre-cancelled with a printed or stamped cancellation and do not need to have a cancellation added. Cancellations can affect the value of stamps to collectors, positively or negatively. Cancellations of some countries ha ...
