"The long march first step"

In real human before landing on Mars, similar trials will do much

Reporter: are Moscow for Mars 500 "test, how much can verify the real manned Mars flight?

ChenShanAn: "Mars 500" experimental simulation from earth flew to Mars, landing on Mars and return to earth in the whole process of total 5.2 days flying.

This is a very meaningful explorations, but is still part of simulation.

Didn't experiment simulating weightlessness environment and is in the ground static test bin, reflect not flight dynamics characteristic. Therefore, this test just miles long march first step. In real human before landing on Mars, similar trials will do much.

Reporter: for the space environmental simulation is very important?

ChenShanAn: yes, as mentioned above weightlessness environment, is very important.

Mankind from leaving earth, enter orbit, landing on Mars surface, again to return to earth, to undergo weightlessness, overweight and low gravity and so on many kinds of gravity environment, haunted by the variation of gravity of bitterness. These changes to the influence of human body, there is a lack of deeply studied in "Mars 500" trials nor corresponding simulation, but the future must be fully verified. Rovers', Mars clothing design and manufacture all want to adapt to the variation of gravity.

In addition, lunar found moon-dust is slight, easy lungs, protective measures, similar problems also existed on Mars.

Reporter: human 40 years ago landed on the moon, why to land on Mars seems still are65?

ChenShanAn: in 1969, the americans first left on the moon for human footprints. Now, many countries have proposed moon goals, but very difficult.

In contrast, to realize the goal of terengganu Mars is much more difficult, flight distance, flight time significantly extend. The moon is nearer to the earth about 38 million kilometers, 5 to 10 days, you will arrive, generally two weeks can perform a round-trip task. While Mars orbit shape for the ellipse, the nearest distance is about 50 million kilometers, the furthest distance is more than 4 million km. Even if choose carrying between, also want to two years.

or by hand mask sufferings

My heart suddenly on a much struck the ripples: contemporary youth is how to save time as gold! Their time treat money, your job depends on the quality of life to my generation shame. I originally carefree in the same way anyway also can be to watch with admiration.

The south is in the telephone petitions wife after hasty decision. Wife came to austral the largest city of care sons already two months to spare. Because does not adapt the hot, humid retting local climate, first muffled neck pain and later developed into an arm numbness, then coughs for long, night particularly severe. Whenever I pick up the phone, heard farther south from her cough sound continuously, I couldn't help pain by heart on, seem to see her cheeks latosolic red, panting, or by hand mask sufferings, mouth simmered or laundry mopping the floor busy housework. I immediately decided to compose broken hand typescripts immediately and increase slow to her.

I quite openly letter "east han discipline of view in a long saying:" would be after the age, but the son of volunteers, we HanYiLongSun, cannot answer know when heard." Therefore, as long as children has needs, we will spare no effort to support, the old couple. In the place of eve to son, myron manders just crossed the 63-year-old birthday. Now she far south, infected body, how don't disturbing? I wish immediately next to her, to help her work, accompany her cure disease made her to recover as soon as possible.
