SpaceCub
SpaceCub was a design project for a homebuilt rocket. Between 1993 and 1994, Geoffrey A. Landis proposed that a vehicle designed to launch to the edge of space might be a feasible project for a "personal" spaceship, the equivalent of a Piper Cub for space. The insight was that a flight to "only" 100 km would reach the officially defined edge of space, and even though this is much easier a challenge than an orbital flight, such a suborbital flight would be of excitement to the public, and the pilot would be officially qualified as an astronaut. A small group of rocket enthusiasts, computer hobbyists, and science-fiction writers gathered together to do a preliminary design, with the ultimate goal of moving on to building a prototype, with (then) physics student David Burkhead leading the technical effort. The vehicle design was discussed in many venues, and presentations on the design progress were given in several conferences, such as the 1995 NSSbr>International Space Devel ...

Piper Cub
The Piper J-3 Cub is an American light aircraft that was built between 1938 and 1947 by Piper Aircraft. The aircraft has a simple, lightweight design which gives it good low-speed handling properties and short-field performance. The Cub is Piper Aircraft's most-produced model, with nearly 20,000 built in the United States. Its simplicity, affordability and popularity invokes comparisons to the Ford Model T automobile. The aircraft is a high-wing, strut-braced monoplane with a large-area rectangular wing. It is most often powered by an air-cooled, flat-4 piston engine driving a fixed-pitch propeller. Its fuselage is a welded steel frame covered in fabric, seating two people in tandem. The Cub was designed as a trainer. It had great popularity in this role and as a general aviation aircraft. Due to its performance, it was well suited for a variety of military uses such as reconnaissance, liaison and ground control. It was produced in large numbers during World War II as the L ...

Orbital Flight
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth, it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around ; this is the boundary of space as defined by NASA, the US Air Force and the FAA. To remain in orbit at this altitude requires an orbital speed of ~7.8 km/s. Orbital speed is slower for higher orbits, but attaining them requires greater delta-v. The Fédération Aéronautique Internationale has established the Kármán line at an altitude of as a working definition for the boundary between aeronautics and astronautics. This is used because at an altitude of about , as Theodore von Kármán calculated, a vehicle would have to travel faster than orbital velocity to derive sufficient aerodynamic lift from the atmosphere to support itself. Due to atmospheric drag, the lowest altitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suborbital Flight
A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the atmosphere or surface of the gravitating body from which it was launched, so that it will not complete one orbital revolution (it does not become an artificial satellite) or reach escape velocity. For example, the path of an object launched from Earth that reaches the Kármán line (at ) above sea level), and then falls back to Earth, is considered a sub-orbital spaceflight. Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the X-15 and SpaceShipOne, and uncrewed ones, such as ICBMs and sounding rockets. Flights which attain sufficient velocity to go into low Earth orbit, and then de-orbit before completing their first full orbit, are not considered sub-orbital. Example ...

Astronaut Badge
The United States Astronaut Badge is a badge of the United States, awarded to military and civilian personnel who have completed training and performed a successful spaceflight. A variation of the astronaut badge is also issued to civilians who are employed with the National Aeronautics and Space Administration as specialists on spaceflight missions. It is the least-awarded qualification badge of the United States military. Eligibility To earn an astronaut badge, a U.S. Air Force or U.S. Navy and Marine Corps officer must complete all required training and participate in a space flight more than above the Earth. The U.S. Army has awarded the badge to officers that have orbited the Earth. In the 1960s, the United States Department of Defense awarded astronaut badges to military and civilian pilots who flew aircraft higher than . Seven USAF and NASA pilots qualified for the astronaut badge by flying the suborbital X-15 rocket spaceplane. American test pilots Michael Me ...

David Burkhead
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David co ...

Space Tourism
Space tourism is human space travel for recreational purposes. There are several different types of space tourism, including orbital, suborbital and lunar space tourism. During the period from 2001 to 2009, seven space tourists made eight space flights aboard a Russian Soyuz spacecraft to the International Space Station, brokered by Space Adventures in conjunction with Roscosmos and RSC Energia. The publicized price was in the range of US$20–25 million per trip. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit. By 2007, space tourism was thought to be one of the earliest markets that would emerge for commercial spaceflight. Russia halted orbital space tourism in 2010 due to the increase in the International Space Station crew size, using the seats for expedition crews that would previously have been sold to paying spaceflight participants. Orbital tourist flights were set to resume in 2015 but the planne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Spaceflight
Private spaceflight is spaceflight or the development of spaceflight technology that is conducted and paid for by an entity other than a government agency. In the early decades of the Space Age, the government space agencies of the Soviet Union and United States pioneered space technology in collaboration with affiliated design bureaus in the USSR and private companies in the US, entirely funding both the development of new spaceflight technologies and the operational costs of spaceflight. The European Space Agency was formed in 1975, largely following the same model of space technology development. However, Arianespace became the world's first commercial launch service provider in the early 1980s. Later on, large defense contractors began to develop and operate space launch systems, derived from government rockets. Private spaceflight in Earth orbit includes communications satellites, satellite television, satellite radio, astronaut transport and sub-orbital an ...
