The advent of robotic machines to the red planet, including NASA’s Perseverance rover this year and China’s Zhurong this month, has led to the inevitable question: When can humans follow? Unauthorized shipments over the decades have illuminated a wide range of information, including the presence of Mars’ ice cap, further exacerbating the anticipation of human arrival. But how soon? Also, are we ready?
NASA wants to send astronauts to Mars, probably sometime by 2030. The United Arab Emirates – now with a spacecraft orbiting the planet – is developing a 100-year plan to build a colony there. While China has said sending people to Mars is its long-term goal, those who aspire to taste Martian’s life can visit a simulation center in the Gobi desert right now.
Most prominent is millionaire Elon Musk.
Founder of Space Exploration Technologies Corp. he wants to send people over the past decade, saying in a speech interview last year he hoped the combined work could be done by 2026. Many scientists, however, warn of too many unanswered questions about space travel. . Musk also acknowledged the danger, saying it was “difficult to pull over there.”
“To be honest, many people may have died in the first place,” the rich man said in an interview with X Prize Foundation founder Peter Diamandis.
Here are some of the major challenges, from surviving radiation and dust storms to producing oxygen and water:
According to the lunar eclipse,
The Apollo spacecraft could fly to the moon in just a few days, but the voyage to Mars would take anywhere between six and nine months. Since the distance between Mars and the Earth varies between 35 million miles and 249 million miles because of its circular paths, there is only a small window available where the two are well organized for space travel. That makes things very difficult.
“There is always the possibility of rescue or provision or supply from Earth or the space station,” said Alice Gorman, a close professor at Flinders University in Adelaide and a member of the advisory council of the Australian Space Industry Association. “It won’t be the same with Mars.”
The Killers of the Sun.
A long flight can expose humans to yet another great fear of space travel: the flames of the sun. The most powerful explosive system in the solar system, the flare is equivalent to 100 million hydrogen bombs. The earth’s magnetic field also protects us from harm, but it does not protect us from extinction for just a few days.
“It’s a horrible way of dying,” said Lewis Dartnell, a professor and expert in astronomy at the University of Westminster in the Department of Health Sciences. He conducted research linked to life on Mars.
The Apollo program did not address the issue, preferring to take the opportunity that a few days of the new moon would not coincide with the solar eclipse. It could be a different story of a multi-month trip to Mars.
The water tanks on the spacecraft could act as shields if placed properly, said Dartnell, so in the event of an opening, passengers could return to the spacecraft version of the panic room surrounded by water tanks. The problem is getting a job in the Sun, especially on the opposite side of the Earth. “How can we make the weather forecast for our space be big enough to be able to provide staff?” he said. “We have no power to look at the Sun from different angles to follow the storms of the sun.”
Radiation is not just a problem along the way. Mars has a much smaller atmosphere than Earth and does not have a global magnetic field, so humans on Earth will be exposed to both solar and cosmic radiation. In addition, the surface itself is very dusty, and severe storms can create dust clouds blocking the Sun, says Nilton Renno, a University of Michigan professor who is interested in his research including astrobiology.
