NASA´s big push for the space station

While concerned about the risks, most space experts who talked privately agreed that further waiting would be unlikely to reduce risks; it was time to do a shakedown under real night conditions.

Frequent problems, including major failures, are expected during the next few months of assembling the station, but experts believe it is an ordeal that must be overcome
