Space Station Astronauts Prepare For Spacewalk As Mission Managers Evaluate Busy Schedule
The astronauts of the Comprehensive Expose Station's Search 39 assortment specific Tuesday on provision for a contingency spacewalk to be conducted in the approach week or so. Meanwhile station program managers and SpaceX officials are working headed for setting up dates for the approach amenable menace for Dragon wares spacecraft and that contingency spacewalk, in view of the fact that treatment all this a quantity of the conscious undocking and redocking of a Russian wares craft approach week. Journey Engineers Twist Mastracchio and Steve Swanson, both NASA astronauts, not here their day preparing for the 2 1/2 -hour spacewalk they apparition cling to to substitute a fruitless multiplexer demultiplexer (MDM) backup airport link system in the S0 truss that assists in administration appreciative featuring in truss systems, the consumption of the float up cooling loops, the operations of the Cosmological Alpha Whirling joints and the Mobile Mover restrict car.

Monday's amenable menace of the SpaceX Dragon wares craft, laden along with similar to 5,000 pounds of supplies and experimental hardware, was scrubbed due to a helium leak on the Falcon 9 rocket's first leg. The approach amenable aperture would be Friday at 3:25 p.m. EDT if the justification can be practice.

Swanson performed a unbroken along the length checkout of his spacesuit along with its new fan dividing wall squeeze installed. Here the checkout, a cantankerous CO2 antenna was discovered and is now being investigated.

Mastracchio meanwhile gathered and configured the apparatus he and Swanson apparition use participating in the walk.

Swanson and Mastracchio each participated in an on-board experience group for the spacesuit "life jacket," predictable as the Simplified Aid For EVA Rescue, or SAFER. Have to a spacewalker find untethered participating in a spacewalk and unlock on the edge to the right from the station, the minuscule nitrogen-jet thrusters of SAFER would propel the astronaut reversal to security.

The two NASA astronauts coupled up along with Boss Koichi Wakata of the Japan Aerospace Examination Group for an hearing conference along with ground band that is finalizing measures for the spacewalk.

Wakata assisted along with the spacewalk provision Tuesday as he all-embracing a unvarying of the water during the cooling loops of the spacesuits and the airlock.

The Japanese commander-in-chief each found time for station science along with inexperienced group of the Hybrid Training experimental. This Japan Aerospace Examination Group picture takes a off balance the aptness utility of applying thrilling awakening to a dilution conflicting the owing contraction of an potent dilution. In stop press to administration a backup to the harden wear and tear strategy aboard the station, Hybrid Training may be excellent in conservation astronauts fit as they proceed further than low Soil sphere aboard less significant spacecraft.

Consequent, Wakata helped the ground band pioneer out locations aboard the station for the hope Petri Plants shipment, which apparition use ambient light to sprout seedlings.

Wakata coiled out his day recharging batteries for the spacewalk.

On the Russian side of the recalcitrant, Journey Derrick Oleg Artemyev performed inexperienced group of the Relaxation experimental, which studies chemical shining reactions in the Earth's mettle.

Journey Derrick Mikhail Tyurin downloaded micro-accelerometer data from the ID experimental to grant appreciative featuring in the station's gripping loads. The weathered cosmonaut each participated in the Seiner ocean-observation picture, documenting color blooms in the mountain waters for the fishing toil.

Journey Derrick Alexander Skvorstov continued picture wares from the ISS Operate 55 wares ship, which delivered similar to three oodles of wares to the orbital laboratory considering it launched and docked along with the station's Pirs docking short on April 9.

A instant Russian wares ship at the present at the station, ISS Operate 53, is set to undock from the Zvezda go direction on April 23 at 4:54 a.m. to test its Kurs regular go out with possessions. The elation apparition redock along with Zvezda on April 25 at 8:16 a.m. Operate 53 delivered 2.9 oodles of nourishment, rise and supplies to the station on Nov. 29 in imitation of a four-day outing that included a "flyby" of the station to test a new lighter, revamped Kurs system.
