Interstellar travel need new mode
Reporter: you think Mars major bottleneck in where?
ChenShanAn: in addition to engineering need breakthrough key technologies, the hardest or person's problem.
Even if one day the manned spacecraft technology breakthroughs, flight process of human problem is still a big challenge. "Mars 500" test in the ground was still not completely simulation of these conditions, practical difficulty. So far, human's longest space flight record is 438 days, is by Russia BoLiYa radio station with spacemen create. While human round-trip Mars, not only so far beyond the limits of human space, but also complete stay Mars etc many complicated work, the astronaut physiological, psychological challenges will is unprecedented.
Reporter: China launched a manned space station project for Mars exploration, what's the meaning of it?
ChenShanAn: manned space station is space-based test of good platform. China manned space station completed, it will provide long-term weightlessness platform of related problems of research.
In fact, in a real manned Mars, and manned moon and months before table residence is an important step. If abandoned manned lunar this link, direct attempt manned Mars, it is extremely risky, astronauts could not get it back.
Reporter: the future of manned Mars is about mode?
ChenShanAn: for future real interstellar exploration, the current mode: I'm afraid not. The traditional craft does not necessarily come in handy, somebody puts forward time shuttle, it sounds with today's cognitive with discrepancies, people think that all matter hard to surpass the speed of light, but with people for the further understanding of the universe, the future possibility to break through this technology. Science new theory to the development of new technologies, will give interstellar travel brings brand-new mode.
