How much is the safe copper coin worth?

If one wanted to go to Mars, there were many factors to consider. ** I. Health risks and countermeasures ** 1. ** Radiation problem ** - Radiation was a big challenge during the trip to Mars. The universe was filled with radiation, such as cosmic rays composed of high-energy charged particles, which could break DNA and increase the risk of cancer. During the 360-day trip from Earth to Mars, the radiation dose received by astronauts was close to the warning value set by NASA, and the radiation dose would be even greater when walking on the surface of Mars. - In order to deal with radiation, the astronauts 'own anti-radiation ability could be improved. For example, if astronauts had some genetic mutations that reduced DNA stability (the risk multiplied in the absence of folate), they needed to supplement folate in their daily diet. Astronauts who had iron in their bodies and were not easy to be digested (in this case, DNA was more fragile in a radiation environment, and they were prone to blood cancer) had blood drawn before they flew, and a diet that limited iron intake during space travel could reduce the risk of radiation. 2. ** Physiologically adapted ** - The environment on Mars and Earth was vastly different. The gravity and air pressure were different, and the human body needed to adapt to these changes. Long-term exposure to microgravity would lead to muscle wasting and bone loss, which required special exercise equipment and programs to maintain physical functions. ** 2. Itinerary related ** 1. ** Journey time ** - The distance between Mars and Earth was constantly changing with the orbit. The nearest was about 55 million kilometers, and the farthest was 400 million kilometers. With the current space technology, it would take 6 - 9 months to travel from Earth to Mars. The entire journey could be divided into a flight phase (about 4 months) and a landing phase. During the flight phase, they had to face challenges such as cosmic radiation and weightlessness in a small space capsule. 2. ** Transportation Method ** - Most of the currently envisioned Mars trips used SpaceX's "Flying Dragon" spacecraft, but aerospace technology was still in development. For example, ion thrusters had high fuel efficiency but low thrust, and nuclear propulsion technology could greatly reduce travel time but was still in the research and development stage. ** 3. Item preparation ** 1. ** Basic Living Resources ** - They had to bring oxygen, water, food, warmth supplies (the temperature difference on Mars was huge), personal hygiene and health supplies, and so on. Because of the low temperature on Mars, water easily boiled and disappeared. Moreover, the China liked to drink warm water, so they needed thermos cups that could maintain a certain amount of pressure. 2. ** Protective Equipment ** - Mars's absorption of ultraviolet-rays was weak, so it was necessary to bring sunblock products. There was no atmospheric protection, so anti-radiation products were needed. Mars was very dry, so it was necessary to take moisture protection measures. 3. ** Entertainment and emotional sustenance items ** - The trip to Mars was lonely and there was a large delay in communication with Earth. You could bring a camera to take photos as a memento. You could also bring some small items such as small figurines to save family photos and videos on the computer to obtain emotional support. The novel "Mars of Paradise" is equally exciting. Everyone is welcome to read it!

I recommend " Rebirth: The Unchaste System ". This was a novel about urban life. The male protagonist, Luo Li, was a slut and was reborn as an 18-year-old. The story was very interesting. The protagonist portrayed a shameless man who was invincible. He had no moral integrity, but he made the readers laugh from beginning to end.

I recommend Run Out of My Life. It's a great sports-sports novel. When the male protagonist, Su Zu, was reborn as a teenager, there was a system that helped him embark on the road of sports competition, focusing on track and field events such as the 100m and 200m. The golden finger was more reasonable. It was built on hard work and sweat. It was not overly exaggerated. The protagonist was mentally mature and trained hard. The supporting characters were also very realistic. There was no brain-dead face-slapping plot. The pace was moderate, the early stages were steady, and the later stages were overpowered.
