Amateur Rocketry
Amateur rocketry, sometimes known as experimental rocketry or amateur experimental rocketry, is a hobby in which participants experiment with fuels and make their own rocket motors, launching a wide variety of types and sizes of rockets. Amateur rocketeers have been responsible for significant research into hybrid rocket motors, and have built and flown a variety of solid, liquid, and hybrid propellant motors. History Amateur rocketry was an especially popular hobby in the late 1950s and early 1960s following the launch of Sputnik, as described in Homer Hickam's 1998 memoir ''Rocket Boys''. One of the first organizations set up in the US to engage in amateur rocketry was the Pacific Rocket Society established in California in the early 1950s. The group did their research on rockets from a launch site deep in the Mojave Desert. In the summer of 1956, 17-year-old Jimmy Blackmon of Charlotte, North Carolina, built a 6-foot rocket in his basement. The rocket was designed to be powere ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ...

HEAT 1X Tycho Brahe
HEAT 1X Tycho Brahe was the first rocket and spacecraft combination built by Copenhagen Suborbitals, a Danish organization attempting to perform the first amateur suborbital human spaceflight. The vehicle consisted of a motor named HEAT-1X and a spacecraft Tycho Brahe. Its launch location was a floating platform named Sputnik. The rocket was test launched twice: In 2010 a power shortage caused a valve to freeze shut, which prevented launch. In 2011 the rocket was successfully launched, reaching an altitude of before the engine was remotely shut off due to a wrong trajectory. Micro Spacecraft Tycho Brahe The Micro Spacecraft (MSC) had a steel pressure hull, and room for one passenger designed and built by Kristian von Bengtson who co-founded Copenhagen Suborbitals. The passenger was able to view the outside through a perspex dome. The occupant flew in a half-standing/half-sitting position, in order to decrease the diameter of the spacecraft. The passenger sat in a specially des ...

Copenhagen Suborbitals
Copenhagen Suborbitals is an amateur, crowd-funded, and open-source human space program. Since its beginning in 2008, Copenhagen Suborbitals has flown five home-built rockets and two mock-up space capsules. Their stated goal is to have one of the members fly into space (above 100 km), on a sub-orbital spaceflight, in a space capsule on the Spica rocket. The organisation was founded by Kristian von Bengtson and Peter Madsen. The organization successfully launched its Nexø II rocket in the summer of 2018. As an amateur organization, the 55 members use their spare time on the project, while at the same time having regular day-jobs. At the annual general assembly, they elect a chairman and board members. , the chairman is Carsten Olsen. History Copenhagen Suborbitals was founded in 2008 by Kristian von Bengtson and Peter Madsen as a non-profit, crowd-funded project where important aspects of the operation were described in detail on blogs and lectures. On 23 February 2014 the bo ...

Model Rocket Motor Classification
Motors for model rockets and high-powered rockets (together, consumer rockets) are classified by total impulse into a set of letter-designated ranges, from ⅛A up to O. The total impulse is the integral of the thrust over burn time. : P_ = \int\limits_^F_(t^)dt^ = F_t. Where t is the burn time in seconds, F_ is the instantaneous thrust in newtons, F_ is average thrust in newtons, and P_ is the total impulse in newton seconds. Class A is from 1.26 newton-seconds (conversion factor 4.448 N per lb. force) to 2.5 N·s, and each class is then double the total impulse of the preceding class, with Class B being 2.51 to 5.00 N·s. The letter (M) would represent the total impulse of between 5,120.01 and 10,240.00 N·s of impulse. Motors E and below are considered low power rocket motors. Motors between F and G are considered mid-power, while motors H and above being high-powered rocket motors. Motors which would be classified beyond O are in the realm of amateur rocketry (in this c ...

Spaceplane
A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered but then landed as unpowered gliders. Four types of spaceplanes have successfully launched to orbit, reentered Earth's atmosphere, and landed: the U.S. Space Shuttle, Russian Buran, U.S. X-37, and the Chinese CSSHQ. Another, Dream Chaser, is under development in the U.S. As of 2019 all past, current, and planned orbital vehicles launch vertically on a separate rocket. Orbital spaceflight takes place at high velocities, with orbital kinetic energies typically at least 50 times greater than suborbital trajectories. Consequently, heavy heat shielding is required ...

Reliant Robin
The Reliant Robin is a small three-wheeled car produced by the Reliant Motor Company in Tamworth, England. It was offered in several versions (Mk1, Mk2 and Mk3) over a period of 30 years. It is the second-most popular fibreglass car in history, with Reliant being the second-biggest British car manufacturer for a time. History Mk. 1 The Robin was first manufactured in October 1973 as a direct replacement for the Reliant Regal. These models feature a 750cc engine, but in 1975, the car gained a number of improvements including an engine boost to 850cc. The Reliant Robin was well received in the 1970s because of good work executed by Ogle Design, (who had previously designed the Bond Bug, and Reliant Scimitar) and affordable price, considering was possible, and orders increased with the 1970s fuel crisis. The final original version of the Robin rolled off the production line in 1982, and after a number of limited editions, including the GBS and the Jubilee, it was replaced by t ...

Top Gear Challenges
''Top Gear'' challenges is a segment of the ''Top Gear'' television programme where the presenters are tasked by the producers, or each other, to prove or accomplish various things related to vehicles. Novelty/stunt challenges Novelty challenges and short stunt films are typically based on absurd premises, such as jumping a bus over motorcycles (instead of the more typical scenario of a motorcycle jumping over buses), or a nun driving a monster truck. These features became less prominent over the life of the programme (they were much more regular during the first four series); they were superseded in later series by the '' "How hard can it be?"'' and '' Cheap car'' challenges, which are much larger in scope. * How fast do you have to drive to be undetected by a speed camera? ''Series One, Episode One'' * How many motorcycles can a double-decker bus jump over? ''Series One, Episode Two'' * Can Grannies do doughnuts?

Black Rock Desert
__NOTOC__ The Black Rock Desert is a semi-arid region (in the Great Basin shrub steppe eco-region) of lava beds and playa, or alkali flats, situated in the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area, a silt playa north of Reno, Nevada that encompasses more than of land and contains more than of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed that is a dry remnant of Pleistocene Lake Lahontan. The Great Basin, named for the geography in which water is unable to flow out and remains in the basin, is a rugged land serrated by hundreds of mountain ranges, dried by wind and sun, with spectacular skies and scenic landscapes. The average annual precipitation ''(years 1971-2000)'' at Gerlach, Nevada (extreme south-west of the desert) is . The region is notable for its paleogeologic features, as an area of 19th-century Emigrant Trails to California, as a venue for rocketry, and as an alternative to the ...
