Space exploration is expensive. It costs nearly £15,000 per kilogram to launch an object into Earth orbit and hence very expensive, in fact as per our info graphic studies. In a financial climate of austerity, should we be ‘wasting' money on what some consider being a luxury? Rather than parking yet another rover on Mars, should we be focusing on more down-to-Earth problems like climate change or world hunger and poverty?
Space exploration is the on-going discovery and exploration of celestial structures in outer space by means of continuously evolving and growing space technology. The physical exploration of space is conducted both by unmanned robotic space probes and human spaceflight, while the study of space is carried out mainly by astronomers with telescopes.
While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. To develop specific military and strategic advantages against other competing countries along with common rationales for exploring space which includes advancing of scientific research, national prestige, uniting different nations and ensuring the future survival of humanity in the earth.
Space exploration has often been used as a proxy competition for geopolitical rivalries such as the Cold War. "Space Race" between the Soviet Union and the United States initiated the early era of space exploration. Landmarks for this initial period were ideally the launch of the first human-made object to orbit Earth, ie the Soviet Union's Sputnik 1, on 4 October 1957, and the first Moon landing by the American Apollo 11 mission on 20 July 1969. After the first 20 years of exploration, the focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station (ISS).
Plans for space exploration by the US remain in flux with the substantial completion of the ISS following STS-133 in March 2011. Constellation, a Bush Administration program for a return to the Moon by 2020 was judged inadequately funded and unrealistic by an expert review panel reporting in 2009.
The European Union, Japan, and India have also planned future crewed space missions In the 2000s, while the People's Republic of China initiated a successful manned spaceflight program. During the 21st century, China, Russia, Japan, and India have advocated crewed missions to the Moon. During the 20th and 21st century, meanwhile, the European Union has advocated manned missions to both the Moon and Mars In the hours after. Curiosity launched, there were more than a few people questioning the worth of spending two and a half billion dollars to launch a spacecraft to Mars.
Obviously, I believe NASA is worth the money. It's difficult to explain briefly why it's worth it as it's such a lot of money. Capability to overcome technological challenges improves by investing in NASA, it makes us smarter and improves our lives. We can accomplish the intangible benefits of pride, respect from other nations, respect for our place in the universe, and hope for a better future. Also, we can accomplish even greater things, even more important.
Spending on space exploration, there are some immediate practical benefits. With the materials that leave Earth, the high costs are not associated (entirely). Instead, they're associated with the technical challenges of building machines to rigorous specifications. The new engineers are developing all kinds of new technologies, to meet those technical challenges; we need lots of very smart engineers. Direct economic benefit by which it is possible to make America one of the few nations in the world capable of revolutionary technological innovation is possible. New technologies can be utilized for a variety of commercial uses. NASA has a website devoted to spinoff technologies; there's a lot more than just Velcro and Tang. Medical, architectural, military, automotive, and artistic applications have pushed NASA technologies just to name a few.
The brains capable of all that innovation stay on earth and are ready to develop more valuable, new ideas Just as important. Many of the NASA Engineers work for commercial clients and the military, too, innovating new solutions to practical problems here on Earth. Building scientific spacecraft is not the portfolio of every engineer at a NASA centre. NASA technologies and space industry engineers make our lives better and give America economic power.
We don't know what we're going to find until we get out there. Maybe nothing. Maybe something that will change everything. We hope for something even better somewhere out there once people have met their basic needs -- food, shelter, security -- they look outward and look for something more. We wonder whether we're the only ones here and also they seek answers to the question of how we got here in the first place. It's just the way we are.
