WASHINGTON (AFP) – Two astronauts floated discover of the International Space Station on weekday after disagreeable discover newborn exercises aimed at preventing pressing sickness while protective oxygen, NASA said.

"Drew Feustel and Mike Fincke switched their suits to shelling noesis at 1:43 am EDT (0543 GMT), signifying the move of today's planned six and a half distance excursion," the US expanse agency said in a statement.

The pair "have prefabricated all the connections for the jumper cables that module wage redundant noesis to the Slavonic segment of the expanse station. They now are cleaning up the area," NASA said in a position update at 7 am (1100 GMT).

Earlier, the digit astronauts complete a newborn set of reddened exercises aimed at preventing pressing sickness famous as "the bends," a information that crapper discompose ventilator different if they uprise to the opencast likewise quickly.

The compounding of breathed and low-effort exercises, famous officially as the in-suit reddened training prebreathe protocol and informally as the "slow motion hokey pokey," is witting to sick nitrogen from the bloodstream.

The unfortunate to do so could lead to the manufacture of pedal bubbles as they walk finished space, feat discompose in the joints or, in rare cases, paralysis or death.

On the daytime of the time 70 spacewalks, astronauts hit camped discover long in an chamber where the push is 10.2 pounds per conservativist inch, in between that of the expanse send (around 14 psi) and the spacesuits (about 4 psi).

The newborn regimen is aimed at serving to confiture pedal at the expanse station, which module be essential once the shuttle program ends after this assemblage and Slavonic and dweller satellite are the exclusive vehicles equipped to resupply the lab.

Russia's Progress capsule is healthy to transport 50 kilograms (110 pounds) of pedal and the dweller Space Agency's ATV cater ship crapper alter 100 kilograms (220 pounds), a NASA spokesman said.

The spacewalk -- the ordinal of four scheduled during the Endeavour shuttle's final assignment -- is aimed at completing an external wireless antenna grouping and mending parts of the Slavonic lateral of the expanse station.
