A new study outlines the problems British researchers had in their 2012 attempt to drill down into a buried Antarctic lake.
The project had been under development for ten years, and yet:
According to the paper, problems started when the boiler that was intended to melt large quantities of snow to provide hot water for the drill failed to work properly because of short-circuiting in its control panel. More severe problems followed. The two parallel drills — one to drill the main borehole to reach the lake, and one to create a reservoir cavity to recirculate drilling water — ran too slowly. Other failures, including of components designed to ensure vertical drilling, exacerbated the problems.
“The drilling was essentially undertaken blindly,” says Siegert. Probably because one or both holes were not drilled vertically, the cavity failed to link with the main borehole. Water also leaked into the cavity drill and froze the hose in the drill hole. Attempts to remove the hose failed, so it had to be cut. At that point, and with not enough fuel left to reach the lake, Siegert gave up.
Seems to me that these problems — some very basic engineering design errors — are a good example of some basic incompetence. If I was providing financial backing to this project I would probably demand that a lot of people be fired before I would give them anymore money.
The report also has this interesting detail which confirms the doubts about the Russian drilling effort:
In 2012, Russian scientists broke into Lake Vostok, by far the largest of Antarctica’s hidden lakes, using a kerosene-fuelled drill. But their samples are spoiled with drill fluid and the bacteria they contain are probably contaminant species.
To environmentalists no warming and more bears means global warming and an endangered species
A U.S. Geological Survey science team has determined that the grizzly bear population has recovered enough that the bear can be taken off the endangered species list.
A report delivered in November by the US Geological Survey’s Interagency Grizzly Bear Study Team describes a resilient and healthy bear population that has adapted to the loss of pine nuts by eating more elk and bison, keeping fat stores at levels that allow the bears to survive and reproduce. For Christopher Servheen, a biologist who oversees grizzly-bear recovery efforts at the Fish and Wildlife Service in Missoula, Montana, that is not surprising. “Bears are flexible,” he says. “It’s easier to say what they don’t eat than what they do eat.”
Not surprisingly, environmental activists don’t like this decision. They claim that, wait for it, global warming threatens the bear enough that it should not be delisted.

Six likely events that will follow an economic crash.
The most pessimistic view: Six likely events that will follow an economic crash.
I have doubts about some of the predicted events, but I have no doubt about the precarious state of the United States’ financial situation, as described here. Nothing good can come from this. Nothing.
A woman spends six weeks trying to cancel an Obamacare insurance policy.
Repeal the damn law: A woman spends six weeks trying to cancel an Obamacare insurance policy.
Ms Hill was told by an ObamaCare operator that she needed to call her insurance company, who passed her back to the Federal Exchange. Ms Hill claims the terminate button on Obamacare’s website did not work, and that she spent ‘several hours a day’ on hold with the Health Insurance Marketplace. Finally, Ms Hill drove to her insurance company’s headquarters in Kansas City, 100 miles from her home, and they were able to help her cancel her ‘Obamacare’ plan.
Remember, Obamacare essentially asks the equivalent of the DMV to handle the complex task of running the nation’s health insurance industry. And we all know how efficient the DMV is!

Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.
Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.
[Rosetta] woke yesterday as planned, to the relief of ESA scientists – but the signal it sent home to confirm it was awake reached Earth late, fraying the nerves of some mission controllers in the meantime. Due to call at 1745 GMT, Rosetta did not announce its revival until 1818. Fifteen minutes could be explained because the spacecraft’s computer checked the on-board clock only every quarter of an hour. The additional 18 minutes, however, was a mystery.
Now, the telemetry has shown that soon after Rosetta’s first revival sequence had started, the on-board computer automatically rebooted and the sequence started again, causing 18 minutes of delay.
It seems all is well now, though the engineers plan to spend some time pinpointing the cause of the reboot.

A village government in New York is trying to take a private grocery using eminent domain in order to replace it with a municipality-owned market.
Theft by government: A village government in New York is trying to take a private grocery using eminent domain in order to replace it with a municipality-owned market.
In a statement, the village said it has “been trying, without success, to engage the Whitneys in substantive discussions” about renovating for the past year. “[A]t various times they have clearly stated their inability or unwillingness to undertake the renovation requirement and despite statements to the contrary, no building plans or architectural drawings of any kind have ever been presented to the village for review,” it said.
But here’s where the story becomes particularly frustrating for Whitney: Four engineers, including two commissioned by the village, reviewed the storm damage on the market and ruled that it was not “substantial,” the store owner’s son, Scott, said. “The repairs that are required due to the flooding . . . do not appear to me to be substantial improvements as defined in the building code,” one of the village-commissioned reports reads.
Nevertheless, despite the findings in the reports, village officials continue to argue that the damage is too much for Whitney to handle. Officials also said the veteran’s submitted plans for repairs are insufficient or incomplete.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.
NASA announced the discovery of the rock at an event at Caltech in Pasadena this past Thursday night, dubbing the rock “Pinnacle Island.” “It’s about the size of a jelly doughnut,” NASA Mars Exploration Rover lead scientist Steve Squyres told Discovery News. “It was a total surprise, we were like ‘wait a second, that wasn’t there before, it can’t be right. Oh my god! It wasn’t there before!’ We were absolutely startled.”
Beautiful machinery.

One must remember that when these images from the 1960s were first taken, it was the very first time humans were seeing our home world from a distance. While today we are somewhat sanguine about such images, then no one knew exactly what the Earth looked like. These images told us.
