The National Aeronautics and Space Administration (NASA) has begun registration for the next generation of American astronauts who wish to be sent to the International Space Station starting this Monday. According to an article published in CNET, residents of the city of Ramsar in northern Iran and a city in Brazil are the best candidates for sending to space. The article states that one of the biggest challenges of sending people to space and to Mars is the issue of radiation emitted from cosmic rays such as the sun and other stars in the galaxy. The Earth's atmosphere and magnetic fields deflect the worst radiations, but Mars lacks a magnetic field, which has led to a significant portion of the planet's atmosphere being lost over millions of years. According to a hypothesis previously proposed by NASA, Mars initially had a magnetic field but lost it billions of years ago due to cooling, causing the ions in its atmosphere to largely separate. CNET further writes that one of the dangers facing astronauts is exposure to these cosmic radiations, and those with stronger bodies are more suitable for space travel. According to this article, researchers have been monitoring Ramsar residents, who experience the highest levels of natural cosmic radiation. This city receives eighty percent more radiation than the global average. The incidence of lung diseases among Ramsar residents is significantly lower than the global average, and the white blood cells that fight cancerous tumors are stronger in Ramsar residents than in the rest of the world. Alongside Ramsar, another city on the Brazilian coast named Guarapari also has high levels of natural radiation, making its residents potentially suitable for space travel. However, unfortunately, none of these individuals can participate in NASA's space program as NASA is currently only registering American citizens. In the U.S., the only place where citizens are physically suitable for space travel in terms of natural radiation exposure is the residents of Colorado. Earlier this fall, NASA announced that new evidence and studies from its scientists have concluded that water flows on the surface of Mars under certain conditions. This unprecedented discovery will enhance research for discovering life on Mars.
The Best Candidates for Space Travel Could Be Residents from Iran and Brazil
NASA has started registering American astronauts for space missions, while a CNET article suggests that residents of Ramsar, Iran, and Guarapari, Brazil, are ideal candidates due to their exposure to high levels of cosmic radiation. However, only American citizens can participate in NASA's program, limiting the potential of these residents despite their unique biological advantages.
👥 Key Players
📰 What Happened
NASA has begun registration for new American astronauts, while a CNET article suggests that residents from Ramsar, Iran, and Guarapari, Brazil, could be ideal candidates for space travel due to their exposure to high levels of cosmic radiation. However, only American citizens are eligible to participate in NASA's program.
- Ramsar residents experience 80% more radiation than the global average.
- NASA's recent findings suggest water flows on Mars, enhancing the potential for discovering life.
💡 Why It Matters
📚 Background
Space travel poses significant health risks due to cosmic radiation, making the study of human resilience in high-radiation environments crucial for future missions.
