An update on the Bigelow inflatable module on ISS
NASA has released an update on the privately built inflatable BEAM module that is presently attached to ISS and is under-going two years of testing.
NASA and Bigelow Aerospace are pleased to report that, overall, BEAM is operating as expected and continues to produce valuable data. Structural engineers at NASA JSC confirmed that BEAM deployment loads upon the space station were very small, and continue to analyze the module’s structural data for comparison with ground tests and models. Researchers at NASA’s Langley Research Center in Hampton, Virginia, have found no evidence of large debris impacts in the DIDS data to date—good news for any spacecraft. And radiation researchers at JSC have found that the dosage due to Galactic Cosmic Rays in BEAM is similar to other space station modules, and continue to analyze local “trapped” radiation particles, particularly from the South Atlantic Anomaly, to help determine additional shielding requirements for long-duration exploration missions.
None of this is a surprise. It seems to me that this testing program is a bit overdone, since NASA never did anything like this in orbit for its own modules. What I think is really happening is that the two-year test of Bigelow’s module was required politically within NASA because there were too many people there opposed to using a privately-built module. I also suspect that NASA got further pressure from the contractors, such as Boeing, who had previously owned this business, and did not want the competition from Bigelow. Thus, despite the fact that Bigelow has already launched two test modules of its own and proved the viability of its designs, it was forced by NASA to do an additional test under NASA’s supervision in order to squelch this opposition.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Robert,

If you are right, on these speculations, then Bigelow may be the big winner. Bigelow now has actual data on the performance of its space modules, but the others may not have similar data.
I am reminded of the (possibly apocryphal) story of the politician who once was accused of being crazy, so he went to a psychiatrist and ever after was able to say, “I’m not crazy, and I have the doctor’s note to prove it. Can my opponent prove that he isn’t crazy?”
Sounds like what Dr. Sheldon Cooper says on The Big Bang Theory:
“I’m not crazy, my mother had me tested” LOL
