at 4 and it reflects at 2‚900 km. also known as the outer core. Wave B is the P-wave because the velocity starts at 8 and it refracts at 2‚900 km. and it refracts at 5‚100 km. also known as the inner core. The mantle starts at 1‚800 km. because wave A and wave B both refract at that point and the outer core starts at 2‚900 km. because wave A reflects from that point and wave B refracts at that point. So the boundary from the mantle to the outer core 1‚100 km. The boundary of the inner core is 5‚100

wondered why is there so much "empty space" in space if there are no other intelligent beings we can communicate with? If this would be true‚ the whole universe would be a complete waste since humans will never be able to explore not one percent of it. Also‚ there is so much evidence about aliens‚ so many sightings and encounters that it is very hard to disprove them all. If the theory of evolution is taken into consideration‚ the possibilities of intelligent life forming only on Earth are so small

“Lawst in Space” The concept of space law‚ an aspect of international law‚ began with United States President Dwight D. Eisenhower’s introduction of the idea into the United Nations in 1957‚ in connection with disarmament negotiations. The United Nations General Assembly assumed responsibility for all outer space matters and discharged it primarily through its Committee on the Peaceful Uses of Outer Space (COPUOS). It was established in 1958‚ shortly after the launch of Sputnik‚ the first

Space exploration has been a major interest among the United States since the space race in the mid-1900’s. Though space exploration may seem vital for expanding the wealth of our nation and enhancing life for us earth dwellers‚ there are certain issues that should be taken into consideration such as costs‚ ethical concerns‚ and the safety of our planet before we launch the rockets. Exploring the solar system is positively viewed by many‚ but most people do not agree with the amount of money

The space race was apart of the Cold War because some believed military installations would be developed in outer space; ultimately‚ impacting the result of the Cold War. Most importantly‚ many developments are direct results of space technologies. For example‚ LEDs‚ infrared ear thermometers‚ anti-icing systems‚ highway safety‚ video enchantments‚ firefighter gear‚ and much more (Jones‚ 2011). The moon landing itself did not provide resources‚ but the technology from the moon benefited the nation

Introduction Space exploration is considered as an innovation‚ creativity and discovery that are facilitated by space technology and that can be used to improve the current technological position of a country. Space exploitation is evident to have several benefits that improve and advance the technology which is essential for making human life easier and simpler. Through various discoveries and explorations of the outer space of the universe

Space science – study of everything in outer space.[1] This has sometimes been called astronomy‚ but recently astronomy has come to be regarded as a division of broader space science‚ which has grown to include other related fields‚[2] such as studying issues related to space travel and space exploration (including space medicine)‚[3] and science performed in outer space (see space research). ContentsPlanetary and Space Science‚ published 15 times per year‚ is a peer-reviewed scientific journal

Introduction A space suit is a garment worn to keep a human alive in the harsh environment of outer space‚ vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure‚ and are necessary for extra-vehicular activity (EVA)‚ work done outside spacecraft. Space suits have been worn for such work in Earth orbit‚ on the surface of theMoon‚ and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment

Jonathan Chen Space Exploration There are many reasons on why space exploration has become a necessity for us‚ as the amount of money being invest on space exploration‚ has increased drastically. From 1950’s the amount of money spend was 89 million which was a large sum of money back then. While we move up in the years the amount of money on space exploration increases‚ for instance in the year 2010 it was the most amount of money spent on space exploration than any other year. A total of 18‚724

Some people believe that money spend on space research is benefits all humanity. Other people take the opposite view and say that money spent in this kind of research is wasted. Tell which point of view you agree with and explain why using specific details and reasons. Since 1950s vast amounts of money have been spent in order to discover the secrets of outer space. Missiles‚ spaceships and satellites have been sent from many nations in various research programs. In order for the governments
