Does anybody know how this went?<br /><br />Orbital Boom Deployment<br />Wednesday, July 27<br />3:54 a.m. EDT<br /><br />Wing Leading Edge/Nose Cap Survey Begins<br />Wednesday, July 27<br />5:24 a.m. EDT <div class="Discussion_UserSignature"> </div>

 

[najab]

The starboard wing leading-edge and the nosecap have been completed. They are about to start the port wing.

No fair locking the thread while I'm in the middle of a reply!!! <br /><br /><font color="yellow">"ehs40 asked: thanks for the info najab but dose any one know how much horse power the shuttle has"</font><br /><br /><font color="orange">"Calli replied: I'm not sure what it would be if expressed in horsepower..."</font><br /><br />Well the term 'horsepower' was, of course, coined to approximate how many horses it would take to pull an equivalent mass as a given engine. In general, this wouldn't be appropriate in comparing to the shuttle, as horses can't really pull the shuttle into orbit. However, if we were to consider the special case of winged horses (aka Pegasus), then we might be able to come up with a specialized horsepower figure.<br /><br />We know that Pegasus can lift one adult human at least (and Perseus was a strapping lad). We will make the assumption that Perseus could have brought his girlfriend along for a moonlight ride around the clouds. I have trouble seeing poor Peggie carrying a third, however, so let's go with that. Figure Perseus weighed in at 180 pounds and his SO at 120. Three-hundred pounds of lift then would be one horsepower (or Pegasus-power -- pp, if you prefer). Since the total thrust of the SSMES and SRBs ia about 7,725,000 pounds -- this would equate to 25,750 pp.

I was recovering from a serious booze session, but heard Andy had some issues with the Boom due to interference (before it sorted out)? Or did I dream that? <img src="/images/icons/wink.gif" />

 

[najab]

I forgot to add, no macroscopic damage found so far.

 

[najab]

No, you didn't dream it. There was an interference problem at first. Also, the pan/tilt assembly isn't working quite right, so they are having to manually change the angles from the programmed pattern.

 

[shuttle_rtf]

That is a pretty damn cool mathematical explanation, Mr Morris.

 

[shuttle_rtf]

Thanking you, Sir.

Should there be sound on the NASA TV feed of the mission.<br /> I'm not hearing any of the dialogue between the shuttle and ground control.... <img src="/images/icons/frown.gif" />

 

[ozspace]

halman, nice description of the shuttle TPS at the end of the previous thread (part 3)<br />

 

[shuttle_rtf]

What about now? Cause I'm hearing Commander Collins talking about reading barcodes to Houston.

 

[jaredgalen]

Yaaaay, have sound now. Had nothing for ages.<br /><br />Seems to have stopped again. Hope they're just not saying anything and that the sound is working. <br /><br />Cheers Shuttle_RTF<br /><br /><br />

 

[ozspace]

I am really surprised that these OBSS sweeps have to be manually performed. You would think that all of the dimensions, angles and arm configurations could all have been pre mapped in 3D and the whole process automated, just hit "execute".

 

[georgeniebling]

it's 9:40 am Central US Time ... I'm watching the NASA TV feed on ComCast Cable .... is that the camera surveying the TPS?

 

[Testing]

Yes it could all be automated as in a CNC mill but the added inertia of the 50' boom extension on the Canada Arm was never planned for in original design. My guess is they were not willing to take the chance of camera or laser head contact with the surface being inspected due to an oscilation induced in the arm. <div class="Discussion_UserSignature"> </div>

 

[Astrosag]

Wondering how I can access the last part of this thread. Anyways, I'm also wondering if anyone (individual or website) has the launch videos from the different camera angles. Thanks for any help.

 

[georgeniebling]

astrosag ... there is a link at the top of this thread that will link to the previous thread (took me a minute to figure it out too).

 

[georgeniebling]

I wish I could figure out what part of teh shuttle they are looking at .... they are also talking to crew (Eileen right now) with proceedure updates for OMS burns and EVA prep)

 

[georgeniebling]

if they are concerned about contact via oscilation ... approximately how far off of the orbiter body *is* the camera? I figured they would use a telephoto type lens to keep the camera "off body"

<font color="yellow">"This is one of those questions..."</font><br /><br />I prefer to invoke mythological creatures, thank you very much. <img src="/images/icons/smile.gif" />

 

[Testing]

It is my understanding that they are using a laser displacment sensor and a camera. <div class="Discussion_UserSignature"> </div>

 

[shuttle_rtf]

Someone's given Marcia Dunn (AP) a brief to go after the chipped tile issue. Poor Paul Hill had that thrown at him twice from her.<br /><br />USA Today's writer seems like she knows her stuff!<br /><br />(On NASA TV in case you're wondering what I'm babbling on about) <img src="/images/icons/smile.gif" />

 

[llivinglarge]

SG, any word on the debris or leading edge data? <br /><br /><br /><br />ISS Crew: Shuttle Discovery, prepare for docking... BTW, did you bring the RTF beer?
