Astronauts would face dangers both getting to and surviving (生存) on Mars. Let's learn about surviving a trip to Mars.
What would it take to keep people safe and healthy on a trip to Mars? Scientists are already working on it, though the trip may be many years later.
Over the last 60 years, many spaceships have flown by orbited(沿轨道运行)and even landed on the Red Planet. However, machines cannot replace humans. That's why the United States, China and other countries want to send people to Mars. But surviving on this trip would not be easy.
A trip to Mars would be the farthest journey in human(人类) history. Mars is about 225 million kilometers away, so it would take astronauts at least 180 days to reach there. However, it only takes a few days to get to the Moon.
Space travel is dangerous. For one thing, staying in space for long periods makes the human body weak. Also, it puts pressure behind the eyes and causes eye problems. But gravity(重力) machines could help.
Then there's space radiation(辐射) to worry about. It is bad for astronauts when they have long journeys. Scientists are working out the issue. They have found that taking certain vitamins can help.
Astronauts will have to pack light to lift off from the earth. But they won't be able to get the things they need easily. Astronauts on the space station practice for this by growing lettuce and other food in space. Engineers are developing 3D printing techniques(技术)which can allow future Mars astronauts to build what they want.
