Space weather expert downplays threat to Earth from solar flare.
My god, a reporter actually talked to a scientist on this subject, instead of the normal political hacks swilling for bigger budgets, and found out that we aren’t going to die!
Opportunity’s target on the rim of Endeavour crater has been dubbed “Spirit Point” by the science team in honor of the now defunct rover.
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.
The remnant of supernova 1987a lights up.
This supernova is the only naked eye supernova since the invention of the telescope, and has been tracked by Hubble for two decades.
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.

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]
Arizona wildfire grows to cover 389,000 acres.
Even in its relatively quiet state: The Sun has a blast.
The Chile volcano eruption and ash cloud is disrupting air traffic throughout South America.
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.

NASA has finally released the photos of Endeavour docked to ISS, taken from a departing Soyuz.
Scientists cheer the election of a socialist president in Peru. Meanwhile, investors flee the country.
And still no one has died from this particular failure: Japan confirms that all three nuclear reactors melted down after the quake and tsunami.
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.”

Some squealing from the journal Science: NSF faces uphill budget battle in Congress.
When he asked the witnesses for ideas on shrinking the government’s $1.6 trillion deficit, Mo Brooks (R-Alabama) [chairman of the research panel of the House of Representatives Science and Technology Committee] made it clear he was talking about possible cuts to NSF’s entire $7 billion budget, not simply its SBE directorate.
Note that in 2008 the NSF budget was a $6.1 billion. Cutting it back to that number would hardly destroy social science research in this country.
The Russian/ESA Mars 500 mission has completed a year of its 520-day simulated flight to Mars.
The crew, who spent 250 days working on maintenance and scientific experiments before a 30-day stint performing tasks on a simulated Martian surface, are currently on their “return trip” to Earth.
This simulated all-male flight is going better than the last:
In 1999, an experiment in the same Moscow warehouse fell to pieces after a Russian team captain forced a kiss on a Canadian woman, and two Russian crewmembers had a bloody fistfight.
Opportunity’s travels on Mars have now exceeded 30 kilometers.
Lockheed Martin buys the first commercial quantum computer. More here on the science of quantum computing.
Quantum computers could revolutionize the way we tackle problems that stump even the best classical computers, which store and process their data as ‘bits’ — essentially a series of switches that can be either on or off. The power of quantum bits — or qubits — is that they can be on and off simultaneously. Connect enough qubits together using quantum entanglement and a computer should be able to zip through a multitude of calculations in parallel, at astonishing speed.
NASA lunar lander test sparked a grass fire yesterday.
Good news for trout fisherman: A new study of the evasive algae Didymo has figured out why the algae blooms in places it shouldn’t.
The result may help managers identify water bodies susceptible to Didymo blooms, and develop management strategies. “It also has the potential to lead to discoveries that may stem this organism’s prolific growth in rivers around in the world,” says [P.V. Sundareshwar of the South Dakota School of Mines and Technology in Rapid City].
The Russian greenhouse on ISS underwent an upgrade today.
The onboard greenhouse was dismantled in April last year, as a need arose to replace the outdated control unit, recalled head of the Rasteniya-2 (Plants-2) experiment, chief of the laboratory of the Institute of Medico-Biological Problems (IMBP) of the Russian Academy of Sciences (RAS) Vladimir Sychev. In early 2010, the crop area of the orbital garden was extended twice – the second leaf chamber was delivered to the ISS in which the crew managed to harvest the Mizuna lettuce, before the greenhouse was dismantled. Now, the cosmonauts will plant in these two chambers different cultures – super-dwarf wheat and dwarf tomatoes.
As I described in detail in Leaving Earth, the Russians have decades of experience in growing plants in space, with the goal of not only providing a natural system to recycle the station’s atmosphere, but also giving the astronauts a morale-boosting activity (gardening) that also gives them something tasty to eat. Though the engineering has still not made it possible to germinate seeds in weightlessness and then have grow there, this will be an absolute requirement if humans are ever to travel to the planets and beyond to the stars.
