A six-hour spacewalk thirteen minutes allowed Tuesday to Alexander Reid Wiseman Gerst and complete various maintenance tasks required on the outside of the International Space Station. It was the first spacewalk for both astronauts .

The first, and critical of this spacewalk was the removed from their temporary storage pump damaged cooling system to be left in a place where it can be stored indefinitely.

is the same as Mike Hopkins and Rick Mastracchio withdrew in December 2013 to replace it with another and re- leaving the cooling system working again one hundred percent.

But even damaged this pump could be used again if necessary by installing an external valve that replaces the one that failed in his Interior; hence the interest in having it stored in a safe place as possible.

Another task much simpler than that of pump move 385 kilograms of mass and 175x127x91 centimeters was to replace the lights in one of the outer chambers of the IEE.

This Wiseman basically had to disconnect the faulty lamp, unscrew and remove it from your site, and make the opposed to the new process.

As a final task Gerst and Wiseman installed a new point of supply electricity to the robot arm movement of the station, which gives more flexibility to use, a task that took two hours due to the high number of wires that had to disconnect and reconnect, plus correct placement.

Wiseman is scheduled another space walk for the next day 15 along with Barry Wilmore to replace a voltage regulator on the electrical system of the station last May, ruling that left crippled one of the eight channels of the ISS electrical system broke down.

Gerst will in this case to be responsible for coordinating the work of Wiseman and Wilmore from inside the station, a task that fell Tuesday ride in Wilmore.

Gerst and Wiseman had in This spacewalk a new absorbent pads inside the helmets of their costumes as well as a kind of breathing tubes similar to those used for snorkelling if a leak like that experienced in his suit Luca Parmitano occurred July 2013 forced to abort a spacewalk.
