The History of The Omega Moon Watch and Nasa

Discovery And Exploration Of The Solar System ... He discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it... Christiaan Huygens followed on from Galileo's discoveries by discovering Saturn's moon Titan and the shape of the rings of Saturn...

IAU Definition Of planet ... According to the definition, there are currently eight planets and five dwarf planets known in the Solar System. The definition distinguishes planets from smaller bodies and is not useful outside the Solar System, where smaller bodies cannot be found yet...

Unmanned NASA Missions ... It began as a U. S. Army proposal to place a scientific satellite into orbit during the International Geophysical Year (1957-58); however, that proposal was rejected in favor of the U. S...

Outer Space ... In 1979, the Moon Treaty made the surfaces of objects such as planets, as well as the orbital space around these bodies, the jurisdiction of the international community...

Space Colonization ... Potential sites for space colonies include the Moon, Mars, asteroids and free-floating space habitats. Ample quantities of all the necessary materials, such as solar energy and water, are available from or on the Moon, Mars, near-Earth asteroids or other planetary bodies...

Planet ... The planets were thought by Ptolemy to orbit the Earth in deferent and epicycle motions. Although the idea that the planets orbited the Sun had been suggested many times, it was not until the 17th century that this view was supported by evidence from the first telescopic astronomical observations, performed by Galileo Galilei...

Apollo Program ... Kennedy's goal was accomplished with the Apollo 11 mission when astronauts Neil Armstrong and Buzz Aldrin landed their Lunar Module (LM) on the Moon on July 20, 1969 and walked on its surface while Michael Collins remained in lunar orbit in the command spacecraft, and all three landed safely on Earth on July 24...

Indian Astronomy ... As with other traditions, the original application of astronomy was thus religious, and would be considered astrology in modern terminology. Hindu astrology was heavily influenced by Hellenistic astrology during the early centuries of the Common Era, notably by the Yavanajataka, a Sanskrit translation of a Greek text disseminated from the 2nd century...

Moon Rock ... There are currently three sources of Moon rocks on Earth: 1) those collected by US Apollo missions; 2) samples returned by the Soviet Union Luna missions; and 3) rocks that were ejected naturally from the lunar surface by cratering events and subsequently fell to Earth as lunar meteorites...

Celestial Navigation ... Celestial navigation is the use of angular measurements (sights) between celestial bodies and the visible horizon to locate one's position on the globe, on land as well as at sea. At a given time, any celestial body is located directly over one point on the Earth's surface...

Giant Impact Hypothesis ... The giant impact hypothesis is the currently favoured scientific hypothesis for the formation of the Moon... Supporting evidence includes: the identical direction of the Earth's spin and the Moon's orbit, Moon samples which indicate the surface of the Moon was once molten, the Moon's relatively small iron core, lower density compared to the Earth, evidence of similar collisions in other star systems (which result in debris disks), and giant collisions are consistent with the leading theories of the formation of the solar system... At present, there is no self-consistent model that starts with the giant impact event and follows the evolution of the debris into a single Moon...

Space Manufacturing ... Economic requirements of space manufacturing imply a need to collect the requisite raw materials at a minimum energy cost. The economical movement of material in space is directly related to the delta-v, or change in velocity required to move from the mining sites to the manufacturing plants...

Cosmology In Medieval Islam ... Allah may be known in two ways: through revelation and by means of reasoning. In the former case, he has conveyed his presence to humankind by sending messengers...

Apollo (spacecraft) ... The design was based on the Lunar Orbit Rendezvous approach: two docked spacecraft were sent to the Moon and went into lunar orbit...

Solar System ... Six of the planets and three of the dwarf planets are orbited by natural satellites, usually termed "moons" after Earth's Moon...

Astronomy In Medieval Islam ... A significant number of stars in the sky, such as Aldebaran and Altair, and astronomical terms such as alhidade, azimuth, and almucantar, are still referred to by their Arabic names. A large corpus of literature from Islamic astronomy remains today, numbering approximately 10,000 manuscripts scattered throughout the world, many of which have not been read or catalogued...

Stability Of The Solar System ... The Solar System is stable in human terms, in that none of the planets will collide with each other or be ejected from the system in the next few billion years, and the Earth's orbit will be relatively stable. Since Newton's law of gravitation (1687), mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, Vladimir Arnold and Jürgen Moser) have searched for evidence for the stability of the planetary motions, and this quest led to many mathematical developments, and several successive 'proofs' of stability for the Solar System...

Space Exploration ... The early era of space exploration was driven by a "Space Race" between the Soviet Union and the United States, the launch of the first man-made object to orbit the Earth, the USSR's Sputnik 1, on October 4, 1957, and the first Moon landing by the American Apollo 11 craft on July 20, 1969 are often taken as the boundaries for this initial period...

History Of Solar System Formation And Evolution Hypotheses ... Just as the Sun and planets were born, so they will eventually die. As the Sun begins to age, it will cool and bloat outward to many times its current diameter, becoming a red giant, before casting off its outer layers (forming what is misleadingly called a planetary nebula) and becoming a stellar corpse known as a white dwarf...

Saturn V ... The largest production model of the Saturn family of rockets, the Saturn V was designed under the direction of Wernher von Braun and Arthur Rudolph at the Marshall Space Flight Center in Huntsville, Alabama, with Boeing, North American Aviation, Douglas Aircraft Company, and IBM as the lead contractors. Von Braun's design was based in part on his work on the Aggregate series of rockets, especially the A-10, A-11, and A-12, in Germany during World War II...

Space Shuttle Retirement ... The Shuttle was originally targeted for retirement in 2010 (Atlantis was to be retired first after STS-132 in May of that year), but the program was extended when the two final planned missions were delayed until 2011. Later, one additional mission was added for Atlantis for July 2011, extending the program further...
