Question

"Imagine space exploration after 50 years from now" in 500 to 1000 words..plzz

Answer 1

Fifty years ago, the Soviet Union launched Sputnik 1, a 183-pound satellite the size of a basketball that did little more than beep out its location as it flew through space.

But that modest satellite, trivial by today's standards, kick-started the Space Age and along with it, the Cold War competition that ultimately put 12 Americans on the moon, led to development of the space shuttle - arguably the most complex vehicle ever built - and prompted the U.S.-led exploration of the solar system.

The Beep That Changed Lives

Homer Hickam, author of "Rocket Boys: A Memoir" (made into the movie "October Sky"), was 14 years old, growing up in Coalwood, West Virginia, on Oct. 4, 1957. His reaction reflected the wonder of the world at the Soviet Union's achievement.

"I read in the paper that Sputnik was actually going to fly over Coalwood and I couldn't imagine that something that big and wonderful would fly over our little town," he told CBS Radio. "So I told my Mom I was going to watch it and she told the neighbor lady and the neighbor lady on down the line there and the next thing I knew we had all these people in the back yard who had come to help little Sonny Hickam, as I was known then, watch Sputnik fly over.

"My dad walked out and said 'Elsie, why are all these people in our yard?' And she said, 'they've come to help Sonny watch Sputnik fly over.' He put on his hat and went up to the mine and said that President Eisenhower would never allow anything Russian to fly over Coalwood. But along Sputnik came and I was so impressed. If God himself had flown over Coalwood at that moment in his golden chariot I would not have been more impressed. And I knew at that moment that somehow I wanted to be part of that great movement into space that Sputnik represented."

Hickam, who went on to a distinguished career that included a long stint as an engineer in the space shuttle program, was not alone. 
Sputnik inspired an entire generation and changed American society in ways that were unimaginable just a few short years before.

One man it had an enormous impact on was John Glenn, one of the original seven Mercury astronauts who became the first American in orbit and followed a distinguished Senate career with a space shuttle flight in 1997.

"I think most Americans just assumed that the U.S. was superior in every way to the Soviet Union," he told CBS, recalling the Sputnik announcement. But the Russians "were bringing thousands of students in from Third World countries, giving them an education, sending them back home, most of the time as doctrinaire communists. And so the jury was still out at that time as to what the wave of the future was going to be."

Citing "McCarthy's antics in the Senate," Glenn said Americans "were not without our own fears of the communist future and here all at once they were doing things that we were not able to do. And so it was sort of a jolt."

A Race, Then A Leap

Spurred by Sputnik and smarting from early Soviet space successes, the United States set about creating what would become the world's most successful space program, developing the Mercury, Gemini and Apollo spacecraft that ultimately carried a dozen Americans to the surface of the moon.

To support the growing space program, America invested in loans and scholarships to attract more interest in science and engineering and financed wide-ranging research that led to a steady stream of technology "spinoffs" that worked their way into all aspects of American society.

Neil Armstrong's "giant leap for mankind" on July 20, 1969, ended the space race that Sputnik began just 12 years earlier. But by that point, the space programs of Russia and the United States were part of each nation's cultural identity and sources of deep national pride.

The Russians focused on building and operating a series of space stations in low-Earth orbit and sending unmanned probes to Venus and Mars. NASA built Skylab and the space shuttle, and ultimately won approval to construct a large "international" space station. Along the way, NASA and the Russians staged the Apo.

Answer 2

Hey mate here is your answer!

When describing known places from memory, patients with left spatial neglect may mention more right- than left-sided items, thus showing representational, or imaginal, neglect. This suggests that these patients cannot either build or explore left locations in visual mental imagery. However, in place description there is no guarantee that patients are really employing visual mental imagery abilities, rather than verbal-propositional knowledge. Thus, patients providing symmetrical descriptions might be using other strategies than visual mental imagery. To address this issue, we devised a new test which strongly encourages the use of visual mental imagery. Twelve participants without brain damage and 12 right brain-damaged patients, of whom 7 had visual neglect, were invited to conjure up a visual mental image of the map of France. They subsequently had to state by pressing a left- or a right-sided key whether auditorily presented towns or regions were situated to the left or right of Paris on the imagined map. This provided measures of response time and accuracy for imagined locations. A further task, devised to assess response bias, used the words “left” or “right” as stimuli and the same keypress responses. Controls and non-neglect patients performed symmetrically. Neglect patients were slower for left than for right imagined locations. On single-case analysis, two patients with visual neglect had a greater response time asymmetry on the geographical task than predicted by the response bias task, but with symmetrical accuracy. The dissociation between response times and accuracy suggests that, in these patients, the left side of the mental map of space was not lost, but only “explored” less efficiently.
