With last week's disappointment of an unmanned cargo mission to the international space station, the U. S. and Russian space agency officials are trying to make out that whether they should pull off those provisional astronauts off the orbiting research skill or not.

Well in this regard, on Monday, a senior official from the U. S. National Aeronautics and Space Administration has said that till now, no final decisions have been worked out and Russian experts are trying their best to find out the reason behind last week's failure, so that they could fix it as soon as possible.

Along with this, they have decided not to leave the $100 billion orbiting laboratory completely on computerized systems.

But then at the same time, NASA has asked the department to produce some contingency plans in detail, with the help of which they can keep some astronauts away from the station.

However, recently in a news conference, Mike Suffredini, who is the manager of the station program for NASA, has asked the space station to reduce the crew from six-person to three-person astronauts, and that too within a term of three weeks. And if they don't succeed in launching two unmanned Soyuz rockets by mid-November, then they would not be allowed to replace these three crew members.
