more suitable for human moved

Core clew

"Mars 500" test, with the real manned Mars flight, compared to how much can simulate true circumstance? Real human landing on Mars will still meet what difficulty and challenge? "Mars 500" experiment project principal, our Chinese manned space engineering astronaut system commander, general designer ChenShanAn revelation this simulation Mars trip.

The human dream in their new home

Mars is current relatively appropriate humans to colonize planets

Reporter: many countries on Mars exploration an interest, still have a lot of science fiction movies and novels is Mars theme. Why do people focus on Mars?

ChenShanAn: human beings on Mars exploration has not stopped, the first is based on people to life in the exploration.

In recent years, people found, earth homes are no longer as beautiful, earth resources can maintain the long, can satisfy human sustainable development requirements?

We in earth orbit flight also discussed, zero gravity will gestate what kind of life? This life in zero gravity growth, the function which changes will happen? From the scientific sense, these studies actually very meaningful, but also involving human ethics problem.
