DSE-Alpha
Deep Space Expedition Alpha (DSE-Alpha), is the name given to the mission proposed in 2005 to take the first space tourists to fly around the Moon. The mission is organized by Space Adventures Ltd., a commercial spaceflight company. The plans involve a modified Soyuz capsule docking with a booster rocket in Earth orbit which then sends the spacecraft on a free return circumlunar trajectory that circles around the Moon once. While the price was originally announced in August 2005 to cost US$100 million per seat, Space Adventures founder Eric Anderson announced in January 2011 that one of the two available seats had been sold for $150 million. Concept Use of the Soyuz spacecraft was considered as the original Soyuz design of 1962 was specifically intended for circumlunar travel. In the late 1960s a stripped down Soyuz variant, under the name Zond, made several attempts at circumlunar flight, with eventual success. The DSE proposal is to launch the Soyuz with one crew member and tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lunar Sortie
A lunar sortie (or lunar sortie mission) is a human spaceflight mission to the Moon. In contrast with lunar outpost missions, lunar sorties will be of relatively brief duration. NASA sorties On 4 December 2006, NASA announced a "Global Exploration Strategy" and lunar architecture that would implement the Vision for Space Exploration. The planned lunar missions would begin with four-person crews making several seven-day sortie missions to the moon until the power supplies, rovers and living quarters of an outpost are operational. Private lunar sorties , Space Adventures is a NewSpace company offering advance booking to allow private individuals to take a future lunar mission involving travel to circumnavigate the Moon. Pricing has been announced at US$100 million per seat. This mission will utilize two Russian launch vehicles. One Soyuz capsule will be launched into low Earth orbit by a Soyuz rocket. Once in orbit, the manned capsule will dock with a second, unmanned, luna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Human Spaceflight Programs
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. , three countries (Soviet Union/Russia, United States and China) and one private company (SpaceX) have launched humans to Earth orbit, and two private companies (Scaled Composites and Blue Origin) have launched humans on a suborbital trajectory. The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale defines spaceflight as any flight over . In the United States professional, military, and commercial astronauts who travel above an altitude of are awarded the United States Astronaut Badge. This article follows the FAI definition of ...

Commercial 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 and or ...

List Of Current And Future Lunar Missions
As part of human exploration of the Moon, numerous space missions have been undertaken to study Earth's natural satellite. Of the Moon landings, Luna 2 of the Soviet Union was the first spacecraft to reach its surface successfully, intentionally impacting the Moon on 13 September 1959. In 1966, Luna 9 became the first spacecraft to achieve a controlled soft landing, while Luna 10 became the first mission to enter orbit. Between 1968 and 1972, crewed missions to the Moon were conducted by the United States as part of the Apollo program. Apollo 8 was the first crewed mission to enter orbit in December 1968, and it was followed by Apollo 10 in May 1969. Six missions landed humans on the Moon, beginning with Apollo 11 in July 1969, during which Neil Armstrong became the first person to walk on the Moon. Apollo 13 was intended to land; however, it was restricted to a flyby due to a malfunction aboard the spacecraft. All nine crewed missions returned safely to the Earth. While the ...

Proton (rocket)
A proton is a stable subatomic particle, symbol , H+, or 1H+ with a positive electric charge of +1 ''e'' elementary charge. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). One or more protons are present in the nucleus of every atom. They provide the attractive electrostatic central force which binds the atomic electrons. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol ''Z''). Since each element has a unique number of protons, each element has its own unique atomic number, which determines the number of atomic electrons and consequently the chemical characteristics of the element. The word ''proton'' is Greek for "first", and this name was given to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called '' khôra'' (i.e. "space"), or in the '' Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of pl ...

Yamal (satellite Constellation)
Yamal (russian: Яма́л) is a Communication satellite, communication and Satellite broadcasting, broadcasting system developed and operated by Gazprom Space Systems. Born out of the connectivity needs of the natural gas extraction giant Gazprom, the system was spun off in its own company, and opened the network to third parties and even went into the public broadcasting industry. Yamal and Russian Satellite Communications Company (RSCC)'s Ekspress (satellite bus), Ekspress constellation are the only two national satellite operators in Russia. History During 1997, even before the launch of their first satellites (Yamal 101 and Yamal 102), Gazprom Space Systems, Gazkom was planning the second generation. At that time, they planned 24 satellites of the second generation. This extremely aggressive plan was scaled back by 2001 with a plan to launch four 200 series satellites. The first two, Yamal 201 and Yamal 202 planned to be launched by 2001 and the second pair, Yamal 203 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Shield
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
