NASA Conducts Second Spacewalk to Fix Coolant Pump on ISS

Expedition 38 astronauts Rick Mastracchio and Mike Hopkins ventured outside the space station on Dec. 24, for the second in a series of spacewalks to remove and replace a faulty coolant pump module. The pump is associated with one of the station's two external cooling loops, which circulate ammonia outside the station to keep both internal and external equipment cool.
The previously planned mission of Orbital Sciences' Cygnus spacecraft has been moved to no earlier than mid-January. The postponement will allow ample time for the station crew to focus on repairing the pump module, which stopped working properly on Dec. 11.

Great video, I watched most of the spacewalk.
This was certainly not an easy job and the complete teamwork is absolutely great to witness.

[@roguemale57]

This is what's needed for the push to Mars-performing on the spot repairs and maintenance.
Great job fellas.

[@smashbeans]

i wanna party on the space station :D

[@MrAirsoftAss]

Remember the risks: Someone pukes or cant pee straight and then everything flies around! :D

[@MARDLAMOCK]

You need to install gopros on the eva suits for better video footage.

13:50 the guy in the corner with the sandwich is like om nom nom lol

[@HondaRider190]

The stories they get to tell their grandchildren! "Yeah, I replaced a coolant pump on the International Space Station."

[@DAREDEVILBKLYN]

Great guys these astronauts, amazing job, way to go NASA !

[@ReplayKCF]

"The true definition of the international space station: a Japanese astronaut operating a Canadian arm with the assistance of a Russian cosmonaut to help two American astronauts in the void of space conducting this spacewalk."

Gravity!!!

Merry Christmas to the Crew ,nice work

[@AtheistRex]

Sheesh! This is a job of work!

[@EagleLogic]

Scott how stupid can you fucking be? Like honestly? How fucking stupid? I need to know. You space hoaxers are fucking ridiculous.

[@tonydoc903]

Hope the astronauts have a happy Christmas on the ISS. All the best , Cheers.

The future is (already) out there. Amazing!

[@nelsonnavarrete6780]

Fantásticamente maravilloso,que capacidades nos ha regalado nuestro generoso Dios.Gracias por compartir video extraordinario.

[@TheXxkornmunkyx666]

Why don't they stream these videos during the live coverage? Its better than the mounted cam they had on mike.

[@FireofOne]

huston you got yourself a new pump module :P

[@dockogugum]

Good luck~

[@jorgecabrera1668]

Uno de mis sueños, ese ese, seguramente nunca viajaré al espacio, asi que...a disfrutar del video :D

[@berndpfe]

Will the actual faulty pump module be removed fom the truss fixture/box and eventually taken into the station for being repaired lateron? Is there a plan for such?

[@KyleStratacusDrewry]

Watch out for space debris! I seen it happen once in a movie.

[@ernestoleon5276]

Impresionante como gira el paquete en esa gravedad y el negro color del espacio sideral mi pregunta que correra por su mente en esa soledad espacial dijo una vez Neil a Aldrin que belleza al ver la tierra es increible y pensar que en vietnam se esta destruyendo el hombre vs hombre en una guerra que esta librandomi pais era 1969.Saludos desde Tijuana,

[@caguitas0]

Amigo Ernesto: Los astronautas son privilegiados al realizar ese rol que les tocó vivir, arriesgando su vida en aras de la ciencia y el progreso de la humanidad...!!!

[@ernestoleon5276]

Contestacion correcta y exacta mi amigo ellos son y fueron privilegiados exceptuando algunos rusos que fueron obligados como Vladimir Komarov y murio al entrar a la atmotfera.

[@caguitas0]

Eso debió haber sido en los inicios de los vuelos espaciales tripulados por humanos. Me imagino por falta de voluntarios.-

[@ernestoleon5276]

Otra vez correcto era la persona indicada y ademas la Rusia era comunista y por EEUU fue el Senador Jhon Gleen pero aqui no fue obligado para ellos fue un volado ir y regresar con vida cuando regreso Jhon Gleen lo recibio JFK y le dijo fue suficiente ya no quiero arriesgarte mejor dedicate a la politica y asi fue pero ya nos habia regalado el pase a la historia.Saludos.

[@caguitas0]

Bonita es la historia.!!!!

[@Tehguy248]

"That would be awkward, yeah"

[@JustinKoenigSilica]

>cooling equipment
>- whatever degrees celsius
i think you need heating equipment.

[@joey8062]

what would happen if a astronaut farted in the space suit, out on a spacewalk.

[@Dakdizzy]

it would get recycled and turn into breathing air.

[@joey8062]

***** lol

[@MiguelCastroBalbi]

Beautiful. ;)

[@AsboJunior]

I wonder how many of thees people kept dropping stuff back on earth because they expected them to float

[@nuclearbox2]

14:35 "Big Gulps huh? Welp, see ya later!"

[@fayzeinc]

This is incredible. Space plumbers. What will NASA need to do next?

[@yannicmeyer421]
