Space shuttle Discovery including its seven crew member blasted into the sky, after four days of its planned launch time. That was done because of a defective vent line, from which dripping of hazardous hydrogen gas was happening. On the other hand, mission managers believed that the two-day repair was a success, after which the external tank was fully filled with fuel and the vent went through an inspection.
There were just only some slight glitches on Sunday night. At a certain time, there was a slow down in helium force in a liquid hydrogen umbilical disconnect. A "red team" consisting of particularly qualified people went to the pad to make manual adjustments in so as to increase the pressure, so the ice wouldn't build up there where liquid hydrogen and oxygen lines go from the tank to the shuttle.
The area was cleansed with helium to avoid the build up of ice and the assembling of gaseous hydrogen and oxygen.At the commencement of the day the weather was only 80 percent but after sometime the weather officers gave a 100 percent clearance for launch of the shuttle.
The operation was reduced down to 13 days and three spacewalks due to the interruption. The team will set up the final piece of the solar arrays, in order to make available the full power to the ISS and thus praise a six member crew.
The Crew members in space settle discovery included the first Japanese astronaut to hang about on board the ISS, and there were other two teachers, including former Dunnellon Middle and Melbourne High science and math teacher Jo Acaba, whose spacewalks will assist in completion of the arrays.
