Mars
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairmont, West Virginia
Fairmont is a city in and county seat of Marion County, West Virginia, United States. The population was 18,313 at the 2020 census. It is the principal city of the Fairmont Micropolitan Statistical Area, which includes all of Marion County, and is a principal city of the larger Morgantown–Fairmont Combined Statistical Area. History Beginnings In the eighteenth century, the earliest development of Fairmont consisted of subsistence farming settlements. In 1789, Boaz Fleming, a Revolutionary War veteran, migrated to western Virginia and purchased a 254-acre farm from Jonathan Bozarth. In 1808, Fleming made his annual trek to Clarksburg to pay his brother's Harrison County taxes. While in Clarksburg, Fleming attended a social gathering that included his cousin Dolley Madison, wife of President James Madison. Fleming complained to Mrs. Madison about having to travel over a hundred miles each year from his home to pay his Monongalia County taxes and his brother's Harris ...

High-Altitude Long Endurance
Atmospheric satellite (United States usage, abbreviated atmosat) or pseudo-satellite (British usage) is a marketing term for an aircraft that operates in the atmosphere at high altitudes for extended periods of time, in order to provide services conventionally provided by an artificial satellite orbiting in space. Atmospheric satellites remain aloft through atmospheric lift, either aerostatic/buoyancy (e.g., balloon (aeronautics), balloons) or lift (force), aerodynamic (e.g., airplanes). By contrast, conventional satellites in Earth orbit operate in the vacuum of space and remain in flight through centrifugal force derived from their orbital speed. To date, all atmosats have been unmanned aerial vehicles (UAVs). Design principles An atmosat remains aloft through atmospheric lift, in contrast to a satellite in Earth orbit which moves freely at high speed in the vacuum of space, and orbits due to its centrifugal force matching the force of gravity. Satellites are expensive to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Aircraft
An autonomous aircraft is an aircraft which flies under the control of automatic systems and needs no intervention from a human pilot. Most autonomous aircraft are unmanned aerial vehicle or drones. However, autonomous control systems are reaching a point where several air taxis and associated regulatory regimes are being developed. History Unmanned aerial vehicles The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, serving as a balloon carrier (the precursor to the aircraft carrier) Significant development of radio-controlled drones started in the early 1900s, and originally focused on providing practice targets for training military personnel. The earliest attempt at a powered UAV was A. M. Low's "Aerial Target" in 1916.Taylor, John W. R.. ''Jane's Pocket Book of Remotely Piloted Vehicles''. Autonomous features such as the autopilot and automated navigation were developed progressively through the twentieth century, although techni ...

Command Center
A command center (often called a war room) is any place that is used to provide centralized command for some purpose. While frequently considered to be a military facility, these can be used in many other cases by governments or businesses. The term "war room" is also often used in politics to refer to teams of communications people who monitor and listen to the media and the public, respond to inquiries, and synthesize opinions to determine the best course of action. If all functions of a command center are located in a single room this is often referred to as a control room. However in business management teams, the term "war room" is still frequently used, especially when the team is focusing on the necessary strategy and tactics to accomplish some goal the business finds important. The war room in many cases is different than a command center because one may be formed to deal with a particular crisis such as sudden unfavorable media, and the war room is convened in orde ...

Air Taxi
An air taxi is a small commercial aircraft that makes short flights on demand. In 2001 air taxi operations were promoted in the United States by a NASA and aerospace industry study on the potential Small Aircraft Transportation System (SATS) and the rise of light-jet aircraft manufacturing. Since 2016, air taxis have reemerged as part of the burgeoning field of eVTOL. Regulation In Canada, air taxi operations are regulated by Transport Canada under Canadian Aviation Regulation 703. The Canadian definition of air taxi includes all commercial single-engined aircraft, multi-engined helicopters flown by visual flight rules by one pilot and all multi-engined, non-turbo-jet aircraft, with a maximum take-off weight or less and nine or fewer passenger seats, that are used to transport people or goods or for sightseeing. In the US, air taxi and air charter operations are governed by 14 CFR Part 135 and 14 CFR part 298 of the Federal Aviation Regulations (FAR).

Distributed Propulsion
In aeronautics, Distributed propulsion is an arrangement in which the propulsive and related air flows are distributed over the aerodynamic surfaces of an aircraft. The purpose is to improve the craft's aerodynamic, propulsive and/or structural efficiency over an equivalent conventional design. Anticipated benefits include improved fuel efficiency, emissions, noise, landing field length and handling. Distributed propulsion may be accomplished by spanwise distribution of partially or fully embedded multiple small engines or fans along the wing. Alternatively, it may involve ducting exhaust gases along the wing's entire trailing edge. Design principles Definition Distributed propulsion on an aircraft is typically characterised not only by the distributed nature of the propulsive thrust but also by utilisation of the effect this has on the aircraft aerodynamics.Epstein, A. H. (2007"Distributed Propulsion: New Opportunities For An Old Concept" MIT. (retrieved 16 June 2022). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DARPA
