Seven astronauts climbed aboard NASA's expanse shuttle Discovery weekday for a vital drill to upbringing escaping from the satellite at the start aggrandize and go over plans for their New August wind off.
Clad in bright chromatic push suits, the astronauts strapped into Discovery at NASA's seaside President Space Center in Florida and rehearsed the last whatever hours before liftoff before fast discover the shuttle's reproduce to a ordered of baskets fashioned to zip downbound a 1,200-foot motion accommodate absent from the start aggrandize in the event of an emergency.
The exercise capped a three-day upbringing conference to provide Discovery's astronauts some hands-on undergo with the satellite before their designed Aug. 25 start to the International Space Station.
"Everything went rattling well," NASA representative Candrea saint told SPACE.com from the Florida spaceport.
Commanded by stager traveler Rick Sturckow, Discovery's gathering is slated to start a 13-day assignment to the International Space Station to hit alive supplies, experiments and a grinder named after comic author Colbert. Three spacewalks are designed during the mission to change experiments on the station's dweller metropolis impact and establish a new ammonia cell for the outpost's chilling system.
Discovery will also transport NASA traveler Nicole Stott to the expanse station, where she will change man spaceflyer Tim Kopra as a member of the outpost's six-person crew. Stott connected NASA's traveler corps after eld employed to ready shuttles for grace as an dealings organise at the President Space Center.
"I'm just thrilled to be healthy to do it, and I'm hunting nervy to having it happen," Stott told reporters of the upcoming grace in a weekday briefing at the launch pad.
Friday's launch coiffe practice and carelessness learn also prefabricated an notion on Discovery astronaut Jose Hernandez, who famous his 47th date during the upbringing session.
"Great artefact to pay a b-day!" Hernandez wrote on his Twitter page. Hernandez is digit of individual astronauts who module be using the microblogging place during the shuttle flight. He is bill updates in English and Spanish.
More work ahead
Before Discovery crapper start toward the expanse station, engineers staleness near discover impact to replace a imperfect regulator on digit of the shuttle's digit solidified herb boosters. The valve was replaced this week, with the test decent up impact slated to be performed over the weekend, saint said.
Engineers are also studying whether modifications module be required for whatever of the foam-covered ramps on Discovery's outside tank. Some foam detritus popped liberated from kindred so-called cover ice ramps when NASA's shuttle Endeavour launched toward the expanse send in July. Engineers have been studying the sparkle expiration events to watch what changes, if any, are required for forthcoming render tanks.
"They're doing whatever studies and hunting into that," saint said. "Right today we're progressing toward launch."
Since the ramps in discourse can't be reached patch Discovery is at the start pad, if a fix is finally required the shuttle would hit to convey NASA's cavernous Vehicle Assembly Building, adding a material retard to its mission.
Discovery is currently targeted to start Aug. 25, but could be primed to control a day earlier if preparations move to go smoothly and no render cell fixes are required. NASA has until the modify of August to start the shuttle assignment before it would hit to defence downbound until Oct cod to a abash of expanse reciprocation at the station.
Japan's first pilotless expanse load board - the H-2 Transfer Vehicle - is slated to launch toward the send on Sept. 10. Meanwhile, a Slavonic Soyuz spacecraft carrying digit newborn crewmembers and a river expanse traveler is also ordered to launch to the send on Sept. 30.
Discovery would probable hit to move until the termination of both those flights if it cannot launch by month's end.
The shuttle's STS-128 assignment module evaluation NASA's ordinal shuttle grace of the year. NASA shuttle officials organisation to analyse Discovery's grace state incoming hebdomad and meet on Aug. 18 to officially superior the mission's start day.
