【Share】MARS 500 crew reaches destination
|

|
The crew of a simulated Mars mission has "touched down" on the Red Planet. Monday's milestone marks the halfway point in an ambitious year-and-a-half isolation experiment, aimed at testing the strains of traveling through the solar system. When two of the six "Mars 500" astronauts performed a spacewalk on Monday, it was their first sortie, after eight months of cramped living in a 160-square-meter module on the outskirts of Moscow. The crew plans to complete two more extra-vehicular jaunts before next week, when the project is scheduled to begin its" return trip". The researchers who enlisted to be locked up in a mock spacecraft for 520 days are from Russia, Europe, and China. The ambitious experiment is the first full-duration simulation of a manned flight to the Red Planet. Martin Zell, Director of ESA-ISS ( european space agency-international space station ) Scientific Program, said, "Our ambition is to have this as controlled as possible, not to have any kinds of glitches, not to have any kinds of sensational things. We just want to do a very smooth mission, a very controlled mission, and to elaborate the means of how to do a real space flight mission in the future." Psychologists say the long confinement was expected to put the team members under tremendous stress, as they grow increasingly tired of each other's company. Such conditions can even be more challenging during an artificial operation than a real flight, because the crew doesn't experience any of the euphoria or dangers of actual space travel. The idea is to closely mimic the timetable of a manned mission to Mars--250 days for the actual journey, a month of orbiting and making surface landings, followed by a 240 days return trip back to Earth--shutting through imaginary cosmos all the way, and totally cut off from their home world. |
