Spacewalkers Require Additional safety precautions for Poisonous ammonia

Spacewalking astronauts are back secure within the International Space Station after ridding their matches of any poisonous ammonia

CAPE CANAVERAL, Fla. -- Spacewalking astronauts needed to take additional security precautions Saturday after potentially getting poisonous ammonia in their suits in the International Space Station's external heating system.

Victor Glover and Mike Hopkins had no difficulty venting and removing a couple old jumper wires to get rid of any ammonia lingering at the traces. But a lot of ammonia spewed from the hose which Mission Control feared a number of the suspended white flakes may have gotten their own suits.

Hopkins was amazed at the quantity of ammonia discharged into the vacuum of space. "Oh yeah, consider this proceed. Can you notice that?" He requested flight controllers. "There is more than I believed."

Though the flow of ammonia was steered from the astronauts and the space station, Hopkins stated some freezing crystals could have contacted his helmet.

"Looks sterile," Hopkins known as down.

NASA didn't need any ammonia getting in the space station and contaminating the cottage atmosphere. The astronauts used very long tools to port the hoses and remained clear of the nozzles, to decrease the probability of ammonia contact.

When the ammonia hoses were emptied, then the astronauts transferred among these into a more central place close to the NASA vibrate, if it is needed on the other end of this channel. The ammonia jumper wires were additional years back after a cooling system flow.

Since the almost seven-hour spacewalk brought to a close, Mission Control reported the astronauts had spent enough time at the sun to inhale off any ammonia residue out of their own suits. Really, after Glover and Hopkins were back indoors, their crewmates said they might smell no ammonia but nevertheless wore gloves while handling the suits.

The hose operate ought to have been finished during a spacewalk per week before, but has been put off and other odd tasks when electricity updates took more than anticipated.

Saturday's additional chores included: substituting an antenna to get helmet cameras, rerouting ethernet wires, tightening connections onto a European experimentation stage, and installing a metal ring to the hatch thermal cover.

Eager to find these channel improvements done prior to the astronauts go home this spring, Mission Control arranged the bonus up spacewalk for both Glover and Hopkins, who started last November on SpaceX. They awakened for back-to-back spacewalks 1 1/2 weeks past and were pleased to chalk up the next.

"It was a fantastic afternoon," Glover said once back indoors.

The spacewalk got began almost an hour , so the guys could replace the communicating caps under their helmets so as to listen correctly. A couple of hours afterwards, Glover's right eye began watering. The aggravation soon passed, but afterwards influenced his left eye.

Subsequently as Glover wrapped up his job, a bolt came aside and drifted off together with the washers, getting the most recent pieces of space junk.

This was the first time spacewalk -- and, barring an emergency, the past -- for this U.S.-Russian-Japanese team of seven. All but one has been headed by NASA.
