What is purpose of space travel?

Human space exploration helps address fundamental questions about our place in the Universe and the history of our solar system. By addressing challenges related to human space exploration, we expand technology, create new industries, and help foster a peaceful connection with other nations. At the time of the 1969 moon landing, many people imagined that, at the beginning of the 21st century, space travel would become routine and that we would visit other planets in our solar system and perhaps even dare to venture into interstellar space. If one day we don't want to follow the path of the dinosaurs, we must protect ourselves from the threat of being hit by a large asteroid.

According to NASA, normally approximately once every 10,000 years, a rocky or iron asteroid the size of a soccer field could hit the surface of our planet and cause tidal waves large enough to flood coastal areas. Originally, a very long list of gadgets, materials and processes was developed for the U.S. UU. Space program, but found other applications on Earth, so many that NASA has an office that seeks ways to reuse space technology as products.

We all know freeze-dried foods, but there are many others. In the 1960s, for example, NASA scientists developed a plastic coated with a metallic reflecting agent. When used on a blanket, it reflects about 80 percent of the user's body heat, an ability that helps accident victims and runners after the marathon stay warm. It needs to detect and prevent a hostile nation or terrorist group from deploying space-based weapons or attacking its navigation, communications and surveillance satellites.

And while she and other major powers, such as Russia and China, are signatories to a 1967 treaty that prohibits nations from claiming territory in space, it's not hard to think of examples of previous treaties that were set aside when someone saw an advantage in doing so. I was a child in the 1960s, a time when many of us believed that one day we would fly out into the cosmos in search of adventure. I can't say precisely when that dream ended for me, but I remember that in the mid-1990s, British folk singer Billy Bragg recorded a song that seemed to capture something of what he was feeling. In The Space Race is Over, Bragg sang about staring intently at the Moon as a child and dreaming that night of walking through the Sea of Tranquility.

We must bear in mind that there are several other motivations behind the astronaut expedition campaign to our heavenly neighbors. These include the desire to overcome our rivals, the belief that space offers a possible refuge from a weakened Earth and the eagerness to exploit the raw materials of the nearby solar system. In our opinion, each of these arguments is in favor of expeditions not with humans, but with our ever better spaceships and explorer robots, at least until the habitats for the shelter of a chosen population are ready. The fundamental question of sending humans into the cosmos is not how easily astronauts can repair instruments in deep space, how quickly they can land on the Moon and build a base there, or why they should travel to Mars and try to create a habitat there.

Saturn has only been explored through unmanned spacecraft launched by NASA, including a mission (Cassini-Huygens) planned and executed in cooperation with other space agencies. A lot of attention has been paid to a private sector company that envisages mining operations on asteroids, but space miners wouldn't have to go that far to find wealth. Radiation is perhaps the most insidious health hazard for space travelers, since it is invisible to the naked eye and can cause cancer. Mariner 2 has been followed by several other flybys by various space agencies, often as part of missions that use a Venus flyby to provide gravitational assistance on the way to other heavenly bodies.

It can be easily seen that space lawyers, who have a growing future ahead of them, can challenge the term “national appropriation”, which does not seem to rule out the operations of private parties that do not directly increase a nation's wealth. The early era of space exploration was driven by a space race between the Soviet Union and the United States. Some spacecraft remain in space indefinitely, others disintegrate during re-entry into the atmosphere, and others reach a planetary or lunar surface to land or impact. The James Webb space telescope, which will replace the now crunchy Hubble next year, will head to the point “L2”, much more popular from an astronomical point of view (due to the second Lagrange point), one million miles from Earth.

Valeri Polyakov's single-spaceflight record of nearly 438 days aboard the Mir space station has not been broken. . .
