I believe that one day humanity will set foot on Mars, and billionaire Elon Musk is most likely to help achieve this goal. In his book The Futurist, Musk describes himself with the phrase " I will be the richest man in the world in 10 years ..." This is not an exaggerated description, but a fact that really happened. Speaking of Musk, from cars to space, no one on Earth is unaware of his achievements, he has done miracles, and Musk has talked more than once about his feat of colonizing Mars.
According to Musk, he is building a powerful spacecraft that will transport volunteers across the vast distance between Earth and Mars. This is Spacex's "Interstellar Flight" program, which can provide unprecedented spacewalk opportunities for human beings to explore the mysteries of the unknown world. This technology has been applied to many fields. But since the trip would take months, SpaceX had to find a way to protect travelers from microgravity during their trip, so Spacex built an artificial gravity starship, so how exactly did it work?
First of all, we must admit that in order to realize the crazy idea of Masco Musk Human Earth Earth Earth Mars there permanently inhabited, artificial gravity starship is crazy. But that's not the crux of the matter, the problem is that if you want a person to leave Earth for another planet to live, you have to have a big enough thrust and the ability to fly out of the atmosphere. That's the main reason he built The Starship, so it should be the most powerful space rocket ever built, after all, it has to be a configurable manned or cargo Starship, and it needs to put more than 100 tons of cargo into orbit.
Mars is a hostile environment. As a result, Musk will have to provide water, food, materials for building bunkers, machines to make rocket fuel, and all the engineering Spacex designed for Starship. At the point of separation, the lowest layer or super heavy booster, consisting of two upper and lower stages, will return to Earth. The spacecraft will refuel in orbit and then travel to Mars to save money. The ship's two stages can be fully reused. The Spacex is a supersonic vehicle that can fly like a bird into space. The booster returned to the ground, checked quickly, and prepared for the next flight. It will have about 30 Raptor engines to propel it. The Raptor engine was designed and developed by SpaceX, which plans to build about 1,000 of these starships, launching at least 3 a day. This will allow Musk to quickly reach his goal of having a population of 1 million on Mars. Of course, Starship isn't just for travel to Mars, nasa plans to use it on its next lunar mission.
The design of starships is relatively simple, but when starships are used to transport people, complications begin to emerge, and it takes months, not days, to get from Earth to Mars. Therefore, in order for the starship to return to Earth safely, it is necessary to ensure that the astronauts have sufficient energy and a long enough travel time. In order to meet these conditions, we have to think about how to increase the speed of the universe. On the way to Mars, passengers will be exposed to the harmful radiation of starship for a long time, of course, this problem can be solved by installing radiation protection equipment on starship, but another problem that is not easy to solve is gravity, which is the key problem.
The effects of microgravity, or even zero gravity, on the human body are self-evident, as scientists explain in Microgravity, once a person is in a state of microgravity, bone loss accelerates by 1% to 1.5% per month, leading to age-related changes, similar to a decline in bone density and the intensity of osteoporosis, which are more pronounced in some bone areas of the pelvic pelvis, although most of the loss is reversible upon return to Earth. But being in a long-term weightless state can also increase the risk of kidney stones and fractures, and staying in space for a long time can also affect muscle mass, leading to a decrease in strength and endurance, especially in the lower limbs. At the same time, it will also change the body's internal environment, such as: blood composition, hormone levels, metabolites and oxygen content, which directly or indirectly affect the performance of body functions. In addition, a decrease in exercise capacity can trigger other diseases. Changes in muscle performance, combined with the effect of microgravity on connective tissue and the need for activity of varying intensities, put astronauts at risk of fatigue and injury on long-term missions. So astronauts in space must use cycle parametrics and treadmills and apply downward pressure to stay healthy.
Musk's SpaceX was the first to handle the effects of microgravity in actual rocket development. The aim is to improve the safety of launch vehicles during flight. The Spacex program has done some work, but there are still many issues to be solved. Some of these concepts are being considered for development, such as the use of planetary propulsion devices, the use of solar wind to drive engines, etc. Spacex's success also illustrates the need for a new technology in the space sector to improve work efficiency. But this new technology has not yet been widely used in commercial satellites. For example, by creating rotating rings that provide artificial gravity, but these methods also have drawbacks, which increase the difficulty of launching and waste fuel; however, Spacex's starships have banded together to use a system of three ships. They moved together, and the system consisted of a payload Starship and a passenger ship on each side and trusses that automatically unfolded and unfolded in the payload bay, so that, as wheel spokes, each passenger ship would be launched separately from Earth, but when connected, the passenger ship would rotate and turn and activate the thrusters to drive the wheels when it produced enough speed. To simulate earth's normal gravity (1g), the spacecraft will be oriented.
For the rest of the journey, the astronauts were once again confronted with a central payload, the Interstellar Ship. They could see a huge outline on the lunar surface, the Rose Driver, which mounted a rotating body made of wheels. Passengers on the spacecraft will feel the drop in the wheel rotational centripetal force, a concept of gravity link that provides a rotating gravity that reuses the main engine and remaining fuel to avoid waste. The key now is the wheeled spokes, and SpaceX must use a spin calculator to simulate the speed of Earth's gravitational pull on a starship. Experts calculated that if the system's radius was about 100 meters, it would have to spin at a speed of 31 meters per second, producing 1g of downforce. Of course, travelers still have to follow a strict exercise routine in order to get to Mars in better health, don't you think? Feel free to leave your comments!
