Human bones taken to ISS for long space flight experiments.

11:13 pm

Human bones were part of the cargo on board the Soyuz capsule launched to ISS today.

“The fragments of human bones will be used to study the causes and dynamics of decalcination of bone tissue in a long space flight,” the head of the experiment, Tatiana Krasheninnikova told Itar-Tass. The problem of decalcination is a headache for medics responsible for spacemen’s health. Researches in this area are conducted by scientists from many ISS member states. However it is impossible to take sample of spacemen’s bones, only their urine is being examined, and a complete picture of dynamics of changes in human bones is not clear, she noted.

A press conference of my very own

3:57 pm

This week the Space Telescope Science Institute in Baltimore, Maryland was holding a conference on the future research possibilities of the James Webb Space Telescope, and ended the conference with a writer’s workshop/press conference today.

Not surprisingly, there was not a lot of press interest. The Webb telescope is way behind schedule and over budget, and is not scheduled for launch until 2018. For most of the press, a press conference now on what Webb might someday do is really nothing more than a NASA sales pitch. Most reporters, including myself, don’t find these kinds of press conferences of much worth.

However, after thinking about it a bit, I decided to go, with the hope that I might be able to find out some more details about the state of the telescope’s construction.

To my astonishment, I discovered how little press interest there was, as it turned out I was the only journalist there! When the presentations ended, the whole workshop became an exercise in answering Bob Zimmerman’s questions about Webb and astronomy. I felt a bit embarrassed about this, but then decided the only stupid question is the one you don’t ask, and forged ahead. Moreover, the situation probably was far more embarrassing for the press people at the Institute then it was for me.

NASA Inspector General notes continuing worries about the Mars Science Lab

10:29 am

A NASA Inspector General report issued today [pdf] notes continuing worries about the Mars Science Laboratory, scheduled for launch later this year.

Remaining Unresolved Technical Issues: Although Project managers have overcome the majority of technical issues that led to the [2009] launch delay, as of March 2011 three significant technical issues remain unresolved. . . . Because of technical issues related to these three and other items, Project managers must complete nearly three times the number of critical tasks than originally planned in the few months remaining until launch.

Whistle-blower claims his accusations cost him his job

9:21 am

A whistle-blower from a Wisconsin research lab claims his accusations cost him his job.

After months of friction that culminated in his openly questioning the reproducibility of data published by his supervisor, a postdoc at the University of Wisconsin–Madison’s zoology department was presented with three options. The department’s chairman said he could wait to be fired, resign voluntarily or accept a “gracious exit strategy” that would give him time to prepare a paper for publication, if he dropped his “scientific misconduct issues”.

When geneticist Aaron Taylor objected that the third option sounded like a “plea bargain” meant to discourage him from pressing his concerns about the lab’s data, the chairman, Jeffrey Hardin disagreed. But Hardin also said: “I think you’d have to decide which is more important to you.” He later added: “You have to decide whether you want to kind of engage in whistle-blowing.” [emphasis mine]

After a burst the Sun quiets down again

3:57 pm

Time again for the monthly updated graph of the Sun’s solar cycle sunspot activity. Posted today by NOAA’s Space Weather Prediction Center, you can see the May results in the graph below.

After a three month steady rise in sunspot activity in January, February, and March, the numbers plummeted during April and May. Though the Sun remains active, with only one blank day since January 16, the pattern of activity as it ramps up to solar maximum continues to suggest that we are looking for the weakest solar maximum in two hundred years, as now predicted by solar scientists at the Marshall Space Flight Center.

Whether this weak maximum foreshadows another Maunder-like minimum, with no sunspots occurring for decades, remains unknown. Only time will tell. However, if such a thing should happen, it will be a marvelous opportunity for scientists to finally pin down precisely the actual influence of the Sun on the Earth’s climate. Up until now they can only guess at how much the Sun varies in brightness. Another Maunder Minimum will tell them.
