Astronaut David Saint-Jacques becomes fourth Canadian to complete spacewalk - lithium ion batteries for sale

LONGUEUIL, Que. —
Astronaut David St.
Jacques became the fourth Canadian to complete the spacewalk on Monday, and in about six years he completed several missions with NASA astronaut Anne McLeanand-a-

Upon entering the space station, he praised the mission as "a glimpse into the future as we explore space further ".
He said that the efforts of the international community are a model of cooperation.
"Because when we try to move beyond our differences, we will achieve what seems impossible," Saint-said . "
Jacques was the first Canadian to walk in space since 2007.
"That's how we make progress.
During the space walk, St.
Jacques reports that McLean's voice is sometimes weak.
The problem worsened as their trip drew to a close.
"We know that once the hatch is closed, it's a hard job and a great relief," said MacLean, once the couple entered the airlock.
In a few minutes, space walkers could barely hear their colleagues through radio circuits.
They had to shout and repeat words from time to time like astronauts on the other side of the hatch.
Meanwhile, Maclean reported a thin layer of moisture in her helmet.
She noted that during the last 15 minutes of the spacewalk, there was a noticeable change in her sun visor.
Since an Italian astronaut almost drowned in a space walk nearly six years ago, because his suit was leaking, NASA has been wary of moisture in his helmet.
McLean insisted that she was not wet and had very little water.
A crew member later noticed the sweat. Saint-
Jacques and McLean started the spacewalk. an-
An hour earlier than scheduled.
Retired astronaut Dave Williams says astronauts prefer to have a cushion on the unpredictable nature of working in space.
"We like to be ahead of schedule and stay ahead because you never know what's going to happen with spacewalk," Williams said at NASA headquarters in suburban Montreal . ".
Williams kept the highest number of Canadian spacewalks, with three out of 2007 spacewalks less than 18 hours outside the space station.
These came at a time when the station was under construction on a large scale.
Now, most of the astronauts are turning to maintenance missions, which partly explains the long gap since Williams's last Canadian spacewalk.
The other two Canadian astronauts were Steve McLean in 2006 and Chris Hadfield in 2001. Saint-
Jacques was his first post on the space station, which began in December. 3.
These tasks took the couple to the entire station, including repositioning the battery adapter board, upgrading the station's wireless communication system, and connecting the jumper cable along the midpoint of the station's main truss, provides an alternative power supply for Canadarm2.
Canadarm2 is a robot hand that is critical to maintaining the space station, and the new cable allows the arm to be repaired during a power outage without the need for space walk.
Williams, he's against St-
Jacques said on Saturday that his compatriots are very excited about the mission and are proud to wear the Canadian flag, but the laser
Focus on future tasks.
This is the third spacewalk for space station passengers in less than three weeks, and most of the work includes replacing 19-year-
The old outpost, which arrived in December, had a new one.
NASA's robotic flight controllers are supporting astronauts from mission control centers in Houston.
With the completion of the human task, the Canadian robot's contribution to the space station will complete the installation of the new lithium ion battery.
"We will be able to use Canadarm2 and Dextre at the cutting edge and automatically complete the movement of these batteries," said Ken Podwalski, CSA space station program manager . ".
Williams said the seemingly clumsy pace of astronauts is necessary to maintain control.
"David did a great job and moved very gracefully, using only the power of his fingertips to walk from one place to another on the space station," Williams said . ".
"This is already a sign of an experienced space Walker.
The astronaut came back in before two o'clock P. M. m.
EDT, may be exhausted for a few times when the body is demanding, no food, only a liter of water in the Western bag.
Williams pointed out that the astronauts spent several years training, exercising under the water and imitating dance choreography.
"Literally, it's years of training for hours of space walking, but it's a great experience," he said . ". Saint-
Jacques, McLean and Oleg Kononenko of the Russian space agency are scheduled to return to Earth in June. —
