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.

Cruise passengers tell of seven-hour security ‘revenge’ nightmare

11:51 am

The abuse of power: Cruise passengers tell of seven-hour security “revenge” nightmare, forced on them by U.S. immigration officials.

But when a handful of them questioned whether the lengthy security checks at the port were strictly necessary for a group of largely elderly travellers officials were not amused. Although they had already been given advance clearance for multiple entries to the country during their trip, all 2,000 passengers were made to go through full security checks in a process which took seven hours to complete.

Density of forests increasing

2:21 pm

The benefits of CO2 increase: The density of the world’s forests has been increasing as they act as a carbon sink.

The authors say most regions and almost all temperate nations have stopped losing forest and the study’s findings constitute a new signal of what co-author Jesse Ausubel of Rockefeller calls “The Great Reversal” under way in global forests after centuries of loss and decline. “Opportunities to absorb carbon and restore the world’s forests can come through increasing density or area or both.”
