The boys sound quite tired, probably did more than they should have, refusing offers to lighten up until very late in the EVA.<br /><br />Just my impression. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Only 57% complete in building the ISS. Seems alot more, and shows the amount of work left

 

[bobblebob]

For god sake asking if Hans had an ear infection. When will the stupid press get it into their heads that Nasa and ESA will NOT talk about his medical condition <br /><br />And from Marcia Dunn again, why cant they just ban her from asking questions.

 

[MeteorWayne]

It's a free press. <br />Journalsts can ask any stupid question they want as many times as they want to.<br /><br />BTW, I am not implying the question is necessarily stupid, but I recall a definition of insanity is performing the same action repeatedly, expecting a different result. <img src="/images/icons/smile.gif" /><br /><br />So the expectation is stupid, or insane. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

The media only get a few questions each conference, and they waste them asking the same question that she knows they wont answer <br /><br />But anway back onto real issues, mission still going great <img src="/images/icons/smile.gif" />

The media sometimes remind me of those stupid annoying dolls, where you <br />pull the cord out of the back & as it slowly winds back in, says the same phrase over & <br />over each time. <img src="/images/icons/laugh.gif" /> <img src="/images/icons/laugh.gif" /> <img src="/images/icons/laugh.gif" /><br /><br />I get the impression that is what is happening here. <img src="/images/icons/rolleyes.gif" /><br /><br />Anyway, great to see Columus is not a part of the ISS. A good job done there.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

I see no mention of this, but the ESA program manager Alan Thirkettle mentions that in 2009 the station will move to a six person crew officially. Now that's some good news right there. So let's see, if we have a full complement on ISS, plus a ferry Soyuz mission and a full shuttle mission in space, we can finally set another record for the most people on orbit at anyone time. Should China launch a mission then as well we can have a total of 19 people on orbit. That's a virtual city!<br /><br /> <div class="Discussion_UserSignature"> </div>

williamt said:<br /><br />"I was wondering - when you're lifting an object of that mass out of the payload bay and swinging it around, is there a significant danger of LOAC (loss of attitude control)? Are the control motion gyroscopes and the thrusters effectively on autopilot for this sort of thing, or do they have to be monitored/controlled manually?"<br /><br />In my mind Newton's third law says pretty clearly that they can swing that laboratory in the way they want and it won't affect to the station:<br /><br />http://en.wikipedia.org/wiki/Newton's_laws_of_motion#Newton.27s_third_law:_law_of_reciprocal_actions<br /><br />So as far as the both things, the station and the laboratory, are connected somehow to each other there is a balance between the forces. However if they are using the robotic arm for example to sling the laboratory down to the earth then it would affect to the station's balance and speed in multiple axis.<br /><br />The only effect comes with the changed aerodynamic drag while moving the object and that force is so small that it is pracitacally zero during the move. And of course gravity will affect a littlebit, but because it is a micro gravity environment, this force is as well basically zero. BTW: What comes to aerodynamic drag I found out that this article at Wikipedia is pretty interesting:<br /><br />http://en.wikipedia.org/wiki/Night_Glider_mode<br /><br />Ok... But now I probably have gone too far from the original topic of this thread. <div class="Discussion_UserSignature"> </div>

Zipi,<br /><br />Welcome to the SDC!<br /><br />When attempting to move objects in zero gravity, torque is translated to both the object and the mover. This is why the astronauts often are held in place by one of the robot arms. When moving an object of substantial mass, the torque is offset by the station gyros, as well as the inertia of the mass of the station. <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>

Does anyone know how long the nitrogen tank is supposed to last before replacement? I don't recall hearing about one being changed out before. <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>

 

[jschaef5]

With STS-124 planned for April 24, is the processing on Atlantis to get ready for LON going to be cutting it pretty close? <div class="Discussion_UserSignature"> </div>

 

[halman]

shuttle_guy,<br /><br />Thanks! I was under the impression that the nitrogen tank was used in cooling the station. What part does it play in Extra-Vehicular Activities? <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>

Thanks all for the posts. I'm too busy to be able to particiate. But its easy to get caught up with your detailed posts. <div class="Discussion_UserSignature"> <p> </p><p><font color="#0000ff"><em>"SCE to AUX" - John Aaron, curiosity pays off</em></font></p> </div>

KDKA and WPSI are doing the crew interviews @ 3:35 central time. <br />I listened to KDKA every morning as a little kid in Pittsburgh. <br />I think it was the second radio station in the country, before the "K" became a western designation.<br /><br />go steelers! <div class="Discussion_UserSignature"> <p> </p><p> <font color="#0000ff">                           www.watchnasatv.com</font></p><p>                          ONE PERCENT FOR NASA! </p> </div>

So pumping most of the air out of the lock first was judged impractical? Clearly this needs to be solved for long term stations or vehicles. (I don't consider ISS to be long-term sustainable - it needs resupply too often.)

 

[MeteorWayne]

If I'm reading it correctly, it has more to do with refilling the lock, than venting it. <br />It is also possible (I don't know for sure) that they may want to have plenty of nitrogen in the refill air as additional protection against the bends. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

[scottb50]

they may want to have plenty of nitrogen in the refill air as additional protection against the bends...<br /><br />Isn't the bends caused by Nitrogen bubbles? Seems like less would be better. <div class="Discussion_UserSignature"> </div>

 

[MeteorWayne]

Again, if I'm right, it has to do with the partial pressure (?) between blood gases and exterior gases. So when pressurized, a higher nitrogen content would protect against dissolution of the blood gases.<br /><br />I could be totally out to lunch here, I don't know the facts, it was a speculation that occurred to me. I am certainly no expert in the subject.<br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

They going to ingress soon? Was meant to happen 15 mins ago and with the MSB in 20 mins, i hope they show it on Nasatv

 

[Testing]

They do the O2 pre-breath and campout procedure prior to EVA to purge out N2. The N2 on repress makes up about 80% of the airlock atmosphere to conserve O2. Don't want any 100% O2 atmosphere. <div class="Discussion_UserSignature"> </div>
