I am now in the second week of my July fund-raising campaign for Behind the Black, celebrating its 14th anniversary. Thank you to everyone that donated so generously last week. I hope week two will do as well.

 

Your donations and subscriptions have allowed me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in the past two weeks has the mainstream media decided to recognize that basic fact.

 

Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuses to recognize this reality.

 

In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

 

Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

 

Please consider supporting my work here at Behind the Black.

Over-the-counter osteoporosis drug appears to keep astronauts from losing bone density on long space flights

Big news: New research on ISS now shows that the standard over-the-counter osteoporosis drugs used by millions on Earth appears to keep astronauts from losing bone density during long space flights.

Beginning in 2009, the group administered the drug to five long-stay astronauts on the International Space Station (ISS), including Koichi Wakata, 48, and Soichi Noguchi, 46. The five took the drug — an over-the-counter bisphosphonate used to treat osteoporosis — once a week starting three weeks before they lifted off until they returned to Earth. The researchers then monitored the astronauts’ bone mass over time and compared the results to those for 14 astronauts that had never taken the drug.

The results showed that the 14 who had never taken the drug had average bone density loss of 7 percent in the femur, and 5 percent in the hip bone. The five astronauts on bisphosphonate, however, only had average bone density loss in the femur of 1 percent, and even a 3 percent increase in the hip bone. Calcium levels in their urine, which rise the more bone mass is lost, were also very low.

If these results hold up, they might very well solve one of the biggest challenges faced by any interplanetary traveler. Up until now, bone loss during long weightless missions never seemed to average less than 0.5 percent per month. After spending three years going to and from Mars, an astronaut could thus lose about almost 20 percent of their bone mass in their weight-bearing bones, and would probably be unable to return to Earth.

Thus, a mission to Mars seemed impossible, unless we could build a ship with some form of artificial gravity, an engineering challenge we don’t yet have the capability to achieve.

If these already tested drugs can eliminate this problem, then the solar system is finally open to us all. All that has to happen now is to do some one to two year manned missions on ISS to test the drugs effectiveness for these long periods of weightlessness.

Genesis cover

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 you can buy it directly from the author and get an autographed copy.

 
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

    This is great news. The only disagreement that I have is in regards to artificial gravity and our technological incapability generate such an environment. All we really need is an acceleration bearing down on the human body, though we don’t know exactly how much is required to keep bone and muscle density within a normal range.

    Space missions with constant thrust would provide such an acceleration. VASIMR Rocket missions, that sort of thing. If we can use these medications to bolster the beneficial effects of any induced accelerations to simulate a gravity vector, then we have indeed removed one of the major impediments to long-term, deep-space crewed missions.

    It continues to boggle my mind that more research into artificial gravity isn’t going on. Gemini 11 proved the basic principle (albeit only generating 0.00015 g…), but since then I’m not aware of any experiments being flown.

    Even if the bone loss issue can be addressed with drugs, weightlessness has plenty of other undesirable effects on the human body.

    Also, without variable gravity research we have no way of knowing what the effects 1/3rd or 1/6th gravity (Mars or Moon) might have.

    Agree Patrick, zero G hurts muscle, immune function, cardio vascular, etc. So bone loss alone is just window dresing.
