![]() ![]() In many fields and industries, the American education system offers the most cutting-edge, soughtafter programs at the world’s best schools. Perhaps one of the most impressive facts is the large number of presidents, prime ministers and leaders from other countries who have experienced the American education system and graduated from a university or school in the USA. These 12 years of schooling (or their equivalent) may also be completed outside the USA, thus giving foreign students the opportunity to pursue the benefits of the American education system and obtain a quality American education. This may be accomplished either at public (or government-operated) schools, or at private schools. ![]() The possibilities are almost endless! The American education system requires that students complete 12 years of primary and secondary education prior to attending university or college. In fact, an international student who elects to take advantage of the American education system can pursue anything from nuclear science to film and dance. According to the paragraph 2, which sentence is CORRECT about the Luna spheres?ĭo you find the American education system to be confusing and different from the education system in your own country? Do you want to attend a university or a school in the USA? The American education system offers international students the most diverse set of options in the world. After the dramatic successes of the 1960s and 1970s, the major space programs turned their attention elsewhere for a period of several decades.Ģ. Before the Apollo project ended in 1972, five other missions and a dozen men had visited the Moon. ![]() Later missions carried a lunar rover that was driven across the satellite’s surface, and saw astronauts spend as long as three days on the Moon. On July 20, 1969, Neil Armstrong and Edwin “Buzz” Aldrin became the first people to reach the Moon when their Apollo 11 lunar lander touched down in the Sea of Tranquility. In total, five lunar orbiter missions photographed about 99 percent of the Moon’s surface. In 19 NASA launched lunar orbiters that were designed to circle the Moon and chart its surface in preparation for future manned landings. Surveyor carried cameras to explore the Moon’s surface terrain, as well as soil samplers that analyzed the nature of lunar rock and dirt. The Surveyor space probes (1966-68) were the first NASA craft to perform controlled landings on the Moon’s surface. Luna 10 launched later that year and became the first spacecraft to successfully orbit the Moon. The small craft was stocked with scientific and communications equipment and photographed a ground level lunar panorama. In 1966 the Soviet spacecraft Luna 9 overcame the Moon’s topographic hurdles and became the first vehicle to soft-land safely on the surface. They spotlighted the challenges of finding a smooth landing site on its surface. Images from all the Ranger missions, particularly Ranger 9, showed that the Moon’s surface was rough. Two years later, however, Ranger 7 streaked toward the Moon with cameras blazing and captured more than 4,000 photos in the 17 minutes before it smashed onto the surface. Unfortunately, Ranger 4 was unable to return any scientific data before slamming into the far side of the Moon. The Ranger missions were kamikaze missions the spacecraft were engineered to streak straight toward the Moon and capture as many images as possible before crashing onto its surface. In 1962 NASA placed its first spacecraft on the Moon-Ranger 4. A third Luna mission subsequently captured the first blurry images of the far–or dark–side of the Moon. Later in 1959, Luna 2 became the first spacecraft to land on the Moon’s surface when it impacted near the Aristides, Archimedes, and Autolycus craters. The craft also returned evidence of space phenomena, such as the steady flow of ionized plasma now known as solar wind. Though Luna 1 did not impact the Moon’s surface, as was likely intended, its suite of scientific equipment revealed for the first time that the Moon had no magnetic field. In January 1959, a small Soviet sphere bristling with antennas, dubbed Luna 1, flew by the Moon at a distance of some 3,725 miles (5,995 kilometers). But aerospace technology developed so rapidly that only about a decade separated the first flyby forays and Neil Armstrong’s history-making steps on the Moon’s surface. The first lunar exploration vehicles of the 1950s were primitive pioneers. The Moon is our close cosmic neighbor, and humans have been exploring its surface ever since they first developed telescopes. Read the following passage and choose the best answer (A, B, C, D): ![]()
