Manned and unmanned flights Traveling in space is dangerous for human beings. Why do we use expensive flights like manned flights that put human beings at risk? In contrast, unmanned spaceflight is cheaper because it operates over long periods of time while using a small amount of energy. More importantly, human beings are not put at risk during space exploration using this approach. Man in space is beneficial because of his ability to make quick judgments about the most effective methods of exploration leading to unexpected discoveries (Baxter). But what is the cost of this exploration? Firstly, man in space is exposed to many chances of developing health problems and financing exploration requires a lot of finances. This can be avoided and achieved almost similar results through the use of unmanned spaceflight. This shows that the future of spaceflight should lie in unmanned spaceflight, as it is evident that it has many advantages over manned flight. Human spaceflight is associated with many dangers for human astronauts. The use of unmanned spaceflight will eliminate all dangers and threats to human beings from space exploration, while effectively utilizing a limited budget. By supporting unmanned spaceflight, humans will be protected from certain diseases, while avoiding unnecessary expenses such as sophisticated survival equipment, food, etc. per flight averages nearly $1.3 billion (Phys Org). When calculated over almost the last five years of the launch, they cost almost $750 million per single launch. This sum includes ...... middle of paper ...... eliminated through the use of unmanned flights. The level of productivity of unmanned flight is high compared to that of manned spaceflight. Supporting a future for unmanned spaceflight is the best option to integrate. And all manned spaceflight should be replaced by unmanned spaceflight, saving many lives.
