Lost British ship found in Arctic after almost 150 years
Using sonar equipment Canadian archeologists have detected the underwater remains of the British ship Investigator, abandoned in the Canadian archipelago of islands by Captain Robert McClure and his crew in 1853. McClure had been sent out to both find the Northwest Passage as well as locate the missing Franklin expedition. As winter had set in in September 1851, however, McClure had anchored the ship for refuge in a bay he named Mercy Bay on the coast of Banks Island. As Pierre Berton noted in his wonderful history of the exploration of the Arctic in the 1800s, The Arctic Grail, Mercy Bay was not a refuge but “a cul-de-sac in which the crew would be confined for the next two years and from which the ship itself would never be freed.” Now, that ship has been rediscovered after almost 150 years.
Picture of the day from Mars
Sand dunes on Mars, from the HiRise camera on Mars Reconnaissance Orbiter:
Fun quote:
These dunes are “barchan” dunes, which are also commonly found on Earth. Barchan dunes are generally crescent-shaped, with their “horns” oriented in the downwind direction. They have a steep slip face (the downwind side of the dune). Barchan dunes form by winds that blow mostly in one direction and thus are good indicators of the dominant wind direction. In this case, the strongest winds blow approximately north to south.
Two predictions of the next solar maximum
Two new predictions of the upcoming solar maximum were published today on the Los Alamos astro-ph preprint webpage. Both call for a weak solar maximum, with one expecting a sunspot number of 92 at maximum while the other predicting a number of 72.

Muslim outreach by NASA
Three citizens of the United Arab Emirates are now the first non-American citizens to train at the NASA Ames Research Center, with more to come, suggesting that NASA Administrator Charles Bolden really meant it when he said his foremost priority was Muslim outreach.

Repair spacewalk scheduled
The first spacewalk to replace the pump module on ISS and thus fix on of the station’s two cooling system is now scheduled for Friday at 6:55 (EDT).

Frog counts flawed?
Scientists have found that the methods used to measure frog populations in the U.S. might be flawed, producing many more false positives than expected and thereby overestimating the populations.

The failure of the past and a hint of the future
The coolant system failure on the International Space Station this weekend and the upcoming spacewalks being planned to fix it is a dramatic and fascinating story, capturing the interest of the general public while causing some news pundits to express fear and dread about science fiction scenerios of disasters in space.
The situation is hardly that death-defying. The station’s cooling systems have a lot of redundancy, all of which are being used to good effect. Moreover, the spacewalk repair to install a replacement pump module, though challenging, is exactly the kind of thing the astronauts have been trained to do. I expect them to do it with few problems. I would be far more surprised if they have serious difficulties and fail to get it done.
What this failure foreshadows, however, is the future on ISS. As the years pass and systems age, » Read more

Met office report
The Met Office in the United Kingdom has issued a report on the state of the climate. In it they state unequivocally that the “world is warming”. Unfortunately, the report fails to address the questions that have been raised about much of the existing climate data, following the climategate scandal.

Closing out debate on climate
It appears that McCarthyism and the blacklist are both alive and well, thriving happily in the field of climate research. Key quote:
It is disturbing, to say the least, that organisations and persons who would be quick to claim professional status consider that it is their current duty to disparage, or to refuse to debate with, or to muzzle scientists whose views on climate change they apparently disagree with.

War between the elites of our society and everyone else. Key quote:
If this election has a theme, it’s going to be the rejection of the elites and a return to a form of populism with a long streak in American history — the demand of citizens to their government to get the hell out of their lives.

Burt Rutan on future of space
At an airshow on Thursday, July 29, in Oskosh, Wisconsin, Burt Rutan, designer of SpaceShipOne, made some interesting remarks about the past and future of private space flight. Key quote:
Rutan said NASA should give 10 to 15 percent of its budget to new space companies like Elon Musk’s SpaceX without regulating how to spend the money. “That would allow them to not (have to) beg for commercial investment, while still working in an entrepreneurial mode.”
