Robert E. Bourdeau
Robert Eugene Bourdeau (February 1, 1922March 5, 2010) was an American physicist known for major contributions to the study of the ionosphere, plasma physics and radio science using space vehicles including satellites and rockets. Among his many achievements was the launch on November 3, 1960, of Explorer 8 from Cape Canaveral, Florida. This occurred during his 16-year career at the National Aeronautics and Space Administration (NASA). He was both Project Manager and Project Scientist for Explorer 8 which added significant knowledge to the understanding of these fields. Prior to his career at NASA Bourdeau worked at the Naval Research Laboratory and participated in the historic post-war V-2 rocket program at the White Sands Proving Ground. There he began his research into the ionosphere. After the V-2 program ended around 1946, Bourdeau concentrated mainly on Department of Defense classified research that included studies of atmospheric electricity. Biography Early years Bour ...

Solar Eclipse Of July 20, 1963
A total solar eclipse occurred on July 20, 1963. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is at least the same size as the Sun's or larger, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with a partial solar eclipse visible over the surrounding region thousands of kilometres wide. Totality was visible from Hokkaido in Japan and Kuril Islands in Soviet Union (now belonging to Russia) on July 21, and Alaska, and Maine in the United States and also Canada on July 20. Astronomer Charles H. Smiley observed the eclipse from a U.S. Air Force F-104D Starfighter supersonic aircraft that was "racing the moon's shadow" at extending the duration of totality to 4 minutes 3 seconds. The moon was 375,819 km (233,523 mi) from the Earth. The moon's apparent d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

Interplanetary Monitoring Platform
Interplanetary Monitoring Platform was a program managed by the NASA Goddard Space Flight Center in Greenbelt, Maryland, as part of the Explorers program, with the primary objectives of investigation of interplanetary plasma and the interplanetary magnetic field. The orbiting of IMP satellites in a variety of interplanetary and earth orbits allowed study of spatial and temporal relationships of geophysical and interplanetary phenomena simultaneously by several other NASA satellites. Satellites Technology The IMP program was the first space program to use integrated circuit (IC) chips, which it first launched into space with the IMP-A ( Explorer 18) in 1963. This predates the use of IC chips in the Apollo Guidance Computer, used for the Apollo program. The MOSFET (metal-oxide-semiconductor field-effect transistor, or MOS transistor) was adopted by NASA for the IMP program in 1964. The use of MOSFETs was a major step forward in spacecraft electronics design. The IMP-D (Explorer 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ariel 1
Ariel 1 (also known as UK-1 and S-55), was the first British satellite, and the first satellite in the Ariel programme. Its launch in 1962 made the United Kingdom the third country to operate a satellite, after the Soviet Union and the United States. It was constructed in the UK and the United States by NASA Goddard Space Flight Center and SERC, under an agreement reached as the result of political discussions in 1959 and 1960. The US Starfish Prime exoatmospheric nuclear test affected Ariel 1's operational capability. Development In late 1959, the British National Committee for Space Research proposed the development of Ariel 1 to NASA. By early the following year the two countries had decided upon terms for the Ariel programme's scope and which organisations would be responsible for which parts of the programme. The UK Minister of Science named the satellite after the sprite in Shakespeare's ''The Tempest''. Three units were constructed: one for prototyping, a flight unit ...

Viking
Vikings ; non, víkingr is the modern name given to seafaring people originally from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.Roesdahl, pp. 9–22. They also voyaged as far as the Mediterranean Sea, Mediterranean, North Africa, Volga Bulgaria, the Middle East, and Greenland, North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a collective whole. The Vikings had a profound impact on the Early Middle Ages, early medieval history of Scandinavia, the History of the British Isles, British Isles, France in the Middle Ages, France, Viking Age in Estonia, Estonia, and Kievan Rus'. Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homer E
Homer (; grc, Ὅμηρος , ''Hómēros'') (born ) was a Greek poet who is credited as the author of the ''Iliad'' and the ''Odyssey'', two epic poems that are foundational works of ancient Greek literature. Homer is considered one of the most revered and influential authors in history. Homer's ''Iliad'' centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The ''Odyssey'' chronicles the ten-year journey of Odysseus, king of Ithaca, back to his home after the fall of Troy. The poems are in Homeric Greek, also known as Epic Greek, a literary language which shows a mixture of features of the Ionic and Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems were originally transmitted orally. Homer's epic poems shaped aspects of ancient Greek culture and education, fostering ideals of heroism, glory, and honor. To Plato, Homer was simply the one who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
