DocM Posted May 26, 2016 Author Share Posted May 26, 2016 Yup. Opening the valve 5 sec at a time. Starting to lengthen. Link to comment Share on other sites More sharing options...
Unobscured Vision Posted May 26, 2016 Share Posted May 26, 2016 Bwahaha ... Williams looks completely nonplussed ... bored, even. "Come on, you weenies. I understand caution, but this is completely ridiculous" is his expression. Give 'er six inches of inflation and hold, sheesh. NASA ... ugh. Painfully, maddeningly slow bunch.

DocM Posted May 26, 2016 Author Share Posted May 26, 2016 They're careful because Genesis unexpectedly popped open in .25 seconds. Don't want more surprises. Link to comment Share on other sites More sharing options...
Unobscured Vision Posted May 26, 2016 Share Posted May 26, 2016 I certainly hope the slight pressure drops between 4.9's are due to expansion .. Link to comment Share on other sites More sharing options...
DocM Posted May 26, 2016 Author Share Posted May 26, 2016 Slightly high on pressure curve. Waiting for it to settle. Link to comment Share on other sites More sharing options...

DocM Posted May 26, 2016 Author Share Posted May 26, 2016 Expansion slow and they're trying to give it time keep to the pressure within the curve. Link to comment Share on other sites More sharing options...

Jim K Global Moderator Posted May 26, 2016 Global Moderator Share Posted May 26, 2016 That's kind of a bummer. Hope they can eventually get it expanded. Did they forget to pack the backup manual expander? Sometimes gotta keep it simple. Unobscured Vision and Beittil 2 Share Link to comment Share on other sites More sharing options...

Draggendrop Veteran Posted May 26, 2016 Veteran Share Posted May 26, 2016 (edited) Hopefully, better luck tomorrow. There was a slight expansion outwards and radially, but not enough till pressure curve exceeded. From what I have read, bladders between the "folds" are being inflated for initial expansion. She has been folded and stored for over a year, may just need a tap. One would think that there is also a direct porting for air into the main chamber as well. But like Doc had mentioned, it could expand violently and cause issues with the ISS seal. /s As long as it expands into a hab and not this... just in...

flyingskippy Posted May 27, 2016 Share Posted May 27, 2016 I wasn't able to watch the coverage of BEAM. Is the problem that it didn't expand enough for the amount of air released or that they released all the air and it didn't expand fully? Link to comment Share on other sites More sharing options...
+John. Subscriber¹ Posted May 27, 2016 Subscriber¹ Share Posted May 27, 2016 Just now, flyingskippy said: I wasn't able to watch the coverage of BEAM. Is the problem that it didn't expand enough for the amount of air released or that they released all the air and it didn't expand fully? Long story short is it didn't do much of anything. Didn't budge anywhere near what they were expecting it to do. Pressures were higher than expected and amount of expansion was much less than expected also.

DocM Posted May 27, 2016 Author Share Posted May 27, 2016 (edited) They were being over cautious, only applying about .45 psi of pressure because the Genesis 1 & 2 subscale orbital testbeds expanded in less than 0.25 second. Too big a risk of damage if a larger structure popped that fast. The last I heard, they were talking about depressurizibg it and possibly trying to loosen the straps. As for why: this thing has been in packed mode for over a year, delayed by the CRS-7 failure and other things. It's possible some stiction has developed between the straps and structure.

flyingskippy Posted May 27, 2016 Share Posted May 27, 2016 Are they talking an EVA then to loosen the straps? Link to comment Share on other sites More sharing options...
