ISS assembly sequence

I don't think you will see NASA cancel the VSE to the moon they have a contract with the private sector and NASA does NOT want to be fined.<br /><br />It would also be a political blow.This is not like the X-33 or the other X programs that was more of test and in the back seen of the public view and the president and NASA did not say yes by 2008 we will have the X-33.<br /><br />Even the fact that NASA was looking for other type of space shuttle it it was in the back seat, that most people if you not a space buff did not know about it <br /><br />And than NASA change their mind thats go the the moon<br /><br />I think this thing thats go to the moon and now this teacher in space is more of a NASA move , thats like thats get kids back intrested in space to support NASA and get more money.<br /><br />NASA was going down a very dark road if the shuttle explode or not because people are just not intrested in space like before and it would not be long to NASA would do away with man space flight and would have no man space flight.<br /><br />It not just intrest in space and NASA the intrest in the sci -fi movies like star trek ,star wars, stargate SG1,battlestar galactica,X-files,fire-fly ,Space Above and Beyond all coming to the end is just shows this .<br /><br />Now there is like no sci -fi space movies now and all you can do is keep watching the old one over and over.<br /><br />And it not just sci -fi and space the math,science and english are all lacking in schools people are not at the proper standards.<br /><br />The university and college are lacking and empty where many of them have to be asians NOW to fill the class.<br /> <br />If any thing wee are de-involving the hot topic of the day now is pop stars ,drama TV,soap opera TV, romance<br />and comedy ,cops and robbers,shooting and car chases .. <div class="Discussion_UserSignature"> </div>

<br /><br />International Space Station facts and figures!! Looks like there is other segment on this mission?<br /><br /><br />-----------------------------------------------------------<br /><br />http://www.nasa.gov/mission_pages/station/main/index.html<br /><br />Already the largest human-made object orbiting the Earth, the International Space Station continued its on-orbit growth spurt with the addition of the Starboard 5 (S5) truss segment. The S5 was attached Saturday during STS-118’s first spacewalk. <br /><br />The S5 will serve as a spacer segment between the Starboard 4 and 6 (S6) segments. The S6 and its solar arrays will be attached during a future shuttle mission. The S5 is the newest piece of the station’s backbone, called the Integrated Truss Structure, which will eventually span the length of a football field and contain four sets of solar arrays. <br /> <div class="Discussion_UserSignature"> </div>

Using almost cuss words on these forums can indeed be taken as a direct violation of the TOS! Besides, you are not posting to people that have no knowledge of these areas, might I suggest that you DO listen to them!!<br /><br />I don't even need to post all kinds of links to be able to use simple logic here. If the ISS is still in reasonably usable shape in 2016 it will still be far to valuable to just bring down in some fiery crash in to the Pacific! <br /><br />Is the ISS worth its cost?? I have given this particular post time and time again (this time I will save it for future reference), and yet every once in awhile it comes up again!<br /><br />First, the opponents to the ISS keep coming up with this $100 billion cost. This is exactly the same kind of thing that opponents to a whole lot of such programs have done to try (sometimes successfully, sometimes not) to kill such programs in the past! This was done while I worked on the B1-A bomber program back in the 1970’s. What the opponents to that worthy program did was to take ALL the development costs, then add the total procurement costs for 100 planes, and then add the estimated maintenance costs for an additional 30 years. So naturally, we were building this $100 billion dollar bomber, and then the opponents could ask: IS this cost worth it? NOT of course saying that they were talking about some 50 years of costs, for an average of some $2 billion per year! In this case they only temporarily set back the program until the Reagan era.<br /><br />And then the opponents to the ISS are now doing the same thing. They link all the early development costs with all the production procurement costs, and all the shuttle flights to the ISS, and then the maintenance costs all the way up till the ISS programmed total life span. So, naturally with this reasoning the ISS is going to cost at least some $100 billion or more! Of course, as the earliest planning for such a station (space station Alpha to Freedom, all before it eve

Lengthy but wise. Thanks for taking the time!<br /><br />Hmm, space welding .. now there's a subject. <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> "<font color="#0000ff"><em>The choice is the Universe, or nothing</em> ... </font>" - H.G Wells </div>

"Hmm, space welding .. now there's a subject. "<br /><br />Oh yes! I'm making an edimacated guess here, I think you should be able to do great welds in space without having to use argon or such gasses to keep out the impurities. <div class="Discussion_UserSignature"> <p> </p><p> </p><p>----------------------------------------------------------------- </p><p>Wanna see this site looking like the old SDC uplink?</p><p>Go here to see how: <strong>SDC Eye saver </strong>  </p> </div>

That is the sort of thing they should be studying on the ISS, in preference to how well spiders make webs in microgravity. Actually I think they did try some soldering experiments at least?

Welding in space is a good one. Particularly if the item is small enough to be taken up. Would be especially good if a high vacuum was needed inside the item. High power electron tubes, thermos bottles.<br /><br />Ball bearings often come up. A blob of steel would solidify very very round. One problem would be controlling the diameter. The blanks would have to be weighed out very carefully beforehand.<br /><br />Ball point pen balls!! <div class="Discussion_UserSignature"> <p> </p><p> </p> </div>

According to this 1987 report on the Salyut stations, they were already experimenting with welding in space. It cites this as a source of some quotes on welding...<br /><br />Gusev, O. "Paton Comments on Results of Space Welding Tests." USSR REPORT,<br />JPRS Publication No. USP-85-003. March 4, 1985. p. 91.<br /><br />The report can be found at: http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19870012563_1987012563.pdf<br /><br />The tool used was described as "Universal Hand-Operated Electron-Beam Power Tool - [Also known as<br />General Purpose, Hand-Operated Tool_ Multipurpose Hand TOOI_ URI]:"<br /><br />Problems encountered with the tool: "-Complaints were made that it was difficult to handle (because<br />the spacesuit was not flexible enough) (See 2°2 Spacesuit.)"<br /><br /><br />

Perhaps the exposed Japanese facility could accomodate at least some research into this and similar subjects? <div class="Discussion_UserSignature"> "<font color="#0000ff"><em>The choice is the Universe, or nothing</em> ... </font>" - H.G Wells </div>
