Very brief descriptions, with appropriate links, of current or recent news items.
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.
Talk about stupid: It seems the legal eagles at NASA have shut down a website that featured a variety of webcams, showing NASA missions.
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.
Archeologists have discovered the largest Roman canal ever built at the mouth of the Tiber river.
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.

More on that failure of the cooling system on ISS. It appears that NASA is gearing up to send two astronauts out for up to two spacewalks to try to fix the problem.
Duck! The Sun has unleashed a coronal mass ejection towards the Earth.
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.
China successfully launches the fifth satellite in its own GPS system.
A failure in the cooling system on the International Space Station yesterday has forced the astronauts to shut down some of their systems while ground control troubleshoots the situation.
Undersea adventure by robot. An unmanned probe completed its first dive beneath the Arctic ice this week.
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.”
Scientists are beginning to unravel the wind patterns on Titan.
After more than six years, it appears that the Mars rover Spirit has finally died. The rover was originally designed to only operate 90 days.
Who are the racists? Readers (and one former editor) respond with dismay because Essence magazine has hired a fashion editor who happens to be white.
Law of unintended consequences strikes again. The new healthcare law has a provision, unrelated to healthcare, that involves a paperwork nightmare for small businesses.
A political note: my Congressman happens to be Steny Hoyer, who waxed poetic recently about taxes and the coming expiration of the Bush tax cuts. Hopefully, this man will free Hoyer from such concerns.
The space war over NASA continues. The pushback from commercial space advocates and industry proponents seems to be having an effect. House aides have indicated that the House NASA authorization bill will not be voted on until September.
The Japanese space agency JAXA has put Hayabusa’s heat shield, outer capsule, and parachute on public display, to large crowds.
Mars Reconnaissance Orbiter takes a picture of the non-face on Mars.
The space war continues. Jeff Foust has two reports today on the political state of NASA’s budget. First, Congress has approved language that requires continuing funding of Constellation. Second, it looks like the House may vote on the new NASA authorization bill this week.
The Mars rover Opportunity has spotted its first dust devil after six-plus years of travel.
Two NASA probes, originally launched to study the Sun and having completed their mission, have had their orbits adjusted so that they can study the Moon instead.
Radar images from Lunar Reconnaissance Orbiter appear to show deposits of approximately 1.6 trillion pounds of water ice on the Moon.
The United Space Alliance, which runs shuttle operations for NASA at Cape Canaveral, has announced layoffs roughly 900 effective October 1. Key quote: “Local workforce officials expect that up to 8,000 KSC employees could lose jobs by the time the shuttle program ends.”
The space war continues. Congressman Frank Wolf (R-Va) of the House Appropriations committee says that there is little chance the NASA budget will be approved until January.
Solar sail engineers from around the world gathered in Brooklyn last week for the Second International Symposium on Solar Sailing. Ben Diedrich, fellow caver, solar sail expert, and the man behind wiki.solarsails.info, gave two papers. He also emailed me to say that “Japan’s contingent gave several talks – many of which compared analysis of deployment, flight, or steering with actual flight data” of Ikaros. A review of the program [pdf] revealed some fascinating uses for solar sails. I like this paper title the best: “Deflecting Apophis with a flotilla of solar sails.” [ed. Apophis is an asteroid with the potential of hitting the Earth.]
Update: Japanese scientists have now announced that they have been able to adjust Ikaros’s attitude using sunlight.
Another update: Ben Diedrich emailed me the link to read the actual proceedings from the conference. See pg 103 to read the paper on using solar sails to deflect Apophis.
An experiment flown in space for 10 days by the European Space Agency has found that three species of lichen can survive the hazards of outer space.
End of the world alert! Scientists have identified an almost half mile wide asteroid with a 1 in 1000 chance of hitting the Earth in 2182.
During a spacewalk at ISS yesterday, two Russian cosmonauts successfully replaced a broken camera and installed new wiring for the recently added Russian Dawn module. They also lost a washer and an “attachment fixture” used to fasten the wiring in place, both of which were spotted floating away.
