morning, astronauts are right now conducting the second and a series of spacewalks to make repairs to a cooling system on the international space station. this is a live stream from nasa tv. today's spacewalk it is scheduled to run over a six hour. we want to bring this left the version out. we got the fault with a low torque. >> standby.

>> copy. standby. >> had a reset. we will reattempt at bravo three. >> he is working on the second of the four bolts that will fix the pump module. it is on the international space station. >> i have another with low torque. >> how many turns? another eight turns. >> approximately seven turns.

>> standby, hopper. i would like to get good torque in the green light. >> copy that. >> begin another. 9.7. approximately another three turns.

>> ok. copy another three turns. standby. hopper, did you get the torque reading on the pgt? >> 9.7 is what this on the -- is what it is saying on the actual. we would like a power cycle of the pgt then reattempt at bravo three. >> the flight director with her

back to the camera. on the far right of your screen, the lead spacewalk officer are discussing pistol grip torque settings. >> we have a green light. this wasan hour ago, removed from its stowage location on a stowage platform holding spare parts. they're holding onto these spare. it was maneuvered at the end. and went over to the platform.on

he slid it into a set of guide rails. now is where the spare pump resides. at the three-hour mark we have had a temporary loss of signal. we will be requiring communications with the station just a few moments from now. >> checking. >> three.
