N-prize
The N-Prize (the "N" stands for "Nanosatellite" or "Negligible Resources".) is an inducement prize contest intended to "encourage creativity, originality and inventiveness in the face of severe odds and impossible financial restrictions" and thus stimulate innovation directed towards obtaining cheap access to space. The competition was launched in 2008 by Cambridge biologist Paul H. Dear, and is intended specifically to spur amateur involvement in spaceflight as it is "aimed at amateurs, enthusiasts, would-be boffins and foolhardy optimists." Dr. Dear died on 11 March 2020, and the prize was subsequently closed. The challenge posed by the N-Prize is to launch a satellite weighing between 9.99 and 19.99 grammes into Earth orbit, and to track it for a minimum of nine orbits. Most importantly the launch budget must be under £999.99 including the launch vehicle, all of the required non-reusable launch equipment hardware, and propellant. In order to be eligible for the awards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanosatellite
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multipl ...

Inducement Prize Contest
An inducement prize contest (IPC) is a competition that awards a cash prize for the accomplishment of a feat, usually of engineering. IPCs are typically designed to extend the limits of human ability. Some of the most famous IPCs include the Longitude prize (1714–1765), the Orteig Prize (1919–1927) and the prizes from the X Prize Foundation. IPCs are distinct from recognition prizes, such as the Nobel Prize, in that IPCs have prospectively defined criteria for what feat is to be achieved for winning the prize, while recognition prizes may be based on the beneficial effects of the feat. History Throughout history, there have been instances where IPCs were successfully utilized to push the boundaries of what would have been considered state-of-the-art at the time. The Longitude Prize was a reward offered by the British government for a simple and practical method for the precise determination of a ship's longitude. The prize, established through an Act of Parliament (the Long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbit
In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbi ...

Flag Of The United Kingdom
The national flag of the United Kingdom is the Union Jack, also known as the Union Flag. The design of the Union Jack dates back to the Act of Union 1801 which united the Kingdom of Great Britain and the Kingdom of Ireland (previously in personal union) to create the United Kingdom of Great Britain and Ireland. The flag consists of the red cross of Saint George (patron saint of England (which also represents Wales)), edged in white, superimposed on the saltire of St Patrick (patron saint of Ireland), also edged in white, which are superimposed on the saltire of Saint Andrew (patron saint of Scotland). Wales is not represented in the Union Flag by Wales's patron saint, Saint David, because the flag was designed whilst Wales was part of the Kingdom of England. The flag proportions on land and the war flag used by the British Army have the proportions 3:5. The flag's height-to-length proportions at sea are 1:2.

Flag Of The United States
The national flag of the United States, United States of America, often referred to as the ''American flag'' or the ''U.S. flag'', consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the Glossary of vexillology#Flag elements, canton (referred to specifically as the "union") bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows, where rows of six stars (top and bottom) alternate with rows of five stars. The 50 stars on the flag represent the 50 U.S. states, and the 13 stripes represent the Thirteen Colonies, thirteen British colonies that declared independence from Kingdom of Great Britain, Great Britain, and became the first states in the U.S. Nicknames for the flag include the ''Stars and Stripes'', ''Old Glory'', and the ''Star-Spangled Banner''. History The current design of the U.S. flag is its 27th; the design of the flag has been modified officially 26 times since 1777. ...

Flag Of South Africa
The flag of South Africa was designed in March 1994 and adopted on 27 April 1994, at the beginning of South Africa's South African general election, 1994, 1994 general election, to replace the flag that had been used since 1928. The flag has horizontal bands of red (on the top) and blue (on the bottom), of equal width, separated by a central green band which splits into a horizontal "Y" shape, the arms of which end at the corners of the hoist side (and follow the flag's diagonals). The "Y" embraces a black isosceles triangle from which the arms are separated by narrow yellow or gold fimbriation, bands; the red and blue bands are separated from the green band and its arms by narrow white stripes. The stripes at the fly end are in the 5:1:3:1:5 ratio. Three of the flag's colours were taken from the flag of the South African Republic, itself derived from the flag of the Netherlands, as well as the Union Jack, while the remaining three colours were taken from the flag of the Afric ...

Flag Of Spain
The national flag of Spain ( es, Bandera de España), as it is defined in the Constitution of 1978, consists of three horizontal stripes: red, yellow and red, the yellow stripe being twice the size of each red stripe. Traditionally, the middle stripe was defined by the more archaic term of , and hence the popular name (red- weld). The origin of the current flag of Spain is the naval ensign of 1785, under Charles III of Spain. It was chosen by Charles III himself among 12 different flags designed by Antonio Valdés y Bazán (all proposed flags were presented in a drawing which is in the Naval Museum of Madrid). The flag remained marine-focused for much of the next 50 years, flying over coastal fortresses, marine barracks and other naval property. During the Peninsular War the flag could also be found on marine regiments fighting inland. Not until 1820 was the first Spanish land unit (The La Princesa Regiment) provided with one and it was not until 1843 that Queen Isabell ...

Rockoon
A rockoon (from ''rocket'' and ''balloon'') is a solid fuel sounding rocket that, rather than being immediately lit while on the ground, is first carried into the upper atmosphere by a gas-filled balloon, then separated from the balloon and ignited. This allows the rocket to achieve a higher altitude, as the rocket does not have to move under power through the lower and thicker layers of the atmosphere. The original concept was developed by Cmdr. Lee Lewis, Cmdr. G. Halvorson, S. F. Singer, and James A. Van Allen during the Aerobee rocket firing cruise of the U.S.S. ''Norton Sound'' on March 1, 1949. A serious disadvantage is that unpiloted balloons cannot be steered, and consequently the location from which the rocket is launched can be uncertain. Therefore, a large area for the fall of the rocket is required for safety reasons. Early atmospheric research ''Time'' magazine reported in 1959: "Van Allen's 'Rockoons' could not be fired in Iowa for fear that the spent rockets ...
