Air leak in Russian section of ISS continuesDmitri Rogozon, the head of Roscosmos, yesterday announced that they will be sending to ISS special equipment for investigating a new air leak in the Russia section of ISS.
This apparently is not the 1-2 inch long crack in the Zvezda module that leaked previously and was found and sealed. Moreover, the article at the link admits that their astronauts found no sign of damage on the outside of Zvezda when they did a space walk in November, suggesting that this first leak was not caused by a micrometeorite hit.
All the known facts so far strongly suggest that the leaks are because of Zvezda’s 20-year-old age, and might be stress fractures caused by the three dozen or so dockings and undockings that have occurred there since its launch.
That the Russians are being so vague about the entire matter reinforces that conclusion. They have never released an image of the first leak, and provided no details about the equipment being sent to the station.
And if Zvezda is beginning to crack due to age, I am not sure what repairs they can do to stop it.
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

Empty it, Isolate it, and kick it free.
Pay Musk to build a replacement and launch fast.
Don’t just quit the Fed. Also quit NASA (at least in the current configuration). Limit NASA to state money management and absolute basic research (space astronomy, planetary research, future technologies, …). No government funding for manned spaceflight that serves no purpose that justifies the enormous government sums that are being spent on it.
Mr. Zimmerman, I understand a little bit your enthusiasm (or rather your obsession) for the planet Mars. It is of course worthwhile to learn as much scientifically as possible about it, although the study of the planet Venus – in terms of knowledge for the development of our planet Earth – is at least, if not more important than Mars in my opinion.
By the way, I don’t believe in the colonization of Mars. He is dead and will just be a beautiful, fascinating corpse in the future. Why should Mars (its atmosphere corresponds technically to a bad vacuum) be colonized if hardly anyone wants to live in the deserts and polar regions of the Earth or in Siberia? That are areas – with right atmosphere, gravity and radiation protection – which are a 1000 times more livable than deadly Mars!
