New Rosetta comet images

6:34 pm

New images from Rosetta have a resolution of 100 meters per pixel and are finding that the neck connecting the comet’s two sections is apparently much brighter than the rest of the nucleus.

As earlier images had already shown, 67P may consist of two parts: a smaller head connected to a larger body. The connecting region, the neck, is proving to be especially intriguing. “The only thing we know for sure at this point is that this neck region appears brighter compared to the head and body of the nucleus”, says OSIRIS Principal Investigator Holger Sierks from the Max-Planck-Institute for Solar System Research (MPS) in Germany. This collar-like appearance could be caused by differences in material or grain size or could be a topographical effect.

It looks like this comet is going to turn out to be one of the most fascinating objects any space probe has visited in a long time.

Soviet spacecraft kidnapped by CIA

6:23 pm

Stranger than fiction: In 1967 the CIA kidnapped a Soviet spacecraft for 24 hours during a global international exhibition tour.

Because the Lunik was guarded 24/7 by Soviets during the second exhibition, the intelligence agents had to wait until the show was over and the Lunik crated for shipment. Then the CIA agents “arranged to make the Lunik the last truckload of the day to leave the grounds,” Finer says. When the Americans made sure no Soviets were on the road watching the truck with the precious cargo as it made its way to the railroad station, “the truck was stopped at the last possible turn-off, a canvas was thrown over the crate and a new driver took over,” Finer says. “The original driver was escorted to a hotel room and kept there for the night.” In a salvage yard, the American experts poked, prodded and photographed the Lunik. Meanwhile, at the railroad yard where the shipment was expected, the Americans got lucky. The Russian waiting to check in the truckloads evidently grew tired, bored, hungry or all three: He left his post to eat dinner and then headed to his hotel to sleep. By 7 a.m., the Russian was back at his post at the rail yard, none the wiser. There he “found the truck with the Lunik awaiting him.”

Out of the Canyon

6:18 pm

We exited the Grand Canyon on schedule at about 1:30 on Thursday. The hike out this year took one hour longer than last year, mostly because we took longer breaks.

As always, the Canyon is a sublime place, hard to describe to those who have never been there and unnecessary to describe for those who have. We hiked in, did an 11 mile hike the one day we were at the bottom, then hiked out today.

Posting will resume but will remain light until I return home on Sunday night.

Eddi Reader – Galileo

6:01 pm

An evening pause:

Galileo fell in love as a Galilean boy
And he wondered what in heaven, who’d invented such a joy.
But the question got the better of his scientific mind
And to his blind and dying day
He’d look up high and love and sighed and sometimes cried,
Who puts the rainbows in the sky?
Who lights the stars in the night?
Who dreamt up someone so divine?
Someone like you and made them mine?

Islamic terrorism and bigotry for all to see.

8:54 pm

The religion of peace: “In a sort of reverse Passover, ISIS activists have marked the homes of Christians with the letter N for “Nassarah,” an Islamic term for Christian, to identify the homes whose inhabitants were to be slaughtered.”

The article also shows, with pictures, the violent nature of the Muslim demonstrations against Israel in France, and the intolerant treatment of Christians by ISIS in Mosul, Iraq.

An exoplanet with an orbit like Mars

8:31 pm

Using Kepler astronomers have discovered a Uranus-sized exoplanet with the longest known orbit, 704 days.

Kepler-421b orbits an orange, type K star that is cooler and dimmer than our Sun. It circles the star at a distance of about 110 million miles. As a result, this Uranus-sized planet is chilled to a temperature of -135° Fahrenheit.

As the name implies, Kepler-421b was discovered using data from NASA’s Kepler spacecraft. Kepler was uniquely suited to make this discovery. The spacecraft stared at the same patch of sky for 4 years, watching for stars that dim as planets cross in front of them. No other existing or planned mission shows such long-term, dedicated focus. Despite its patience, Kepler only detected two transits of Kepler-421b due to that world’s extremely long orbital period.

The planet’s orbit places it beyond the “snow line” – the dividing line between rocky and gas planets. Outside of the snow line, water condenses into ice grains that stick together to build gas giant planets.

Going back to the Canyon

11:01 am

Grand Canyon
The black dot in the upper left is a condor.

As we did last year Diane and I are heading back to the Grand Canyon today. We will hike down to Phantom Ranch on Tuesday and return on Thursday, with one day at the bottom to do additional hiking. We then head to Grand Canyon Caverns to participate in a dig project there trying to find additional virgin passage. (When we were there last year we broke into approximately 250 feet of previously unknown passage.)

Obviously, posting will be impossible while we are in the Canyon. I should be able to post on the other days, though not as frequently as normal.

The Evening Pause, however, will appear each night this week, with thanks to my readers for helping me find some really interesting videos.

More destroyed evidence at the IRS

10:39 am

Working for the Democratic Party: The IRS now reports that as many as 20 individuals under investigation for the agency’s harassment of Obama’s political opponents have had computer crashes, losing their emails.

IRS Deputy Associate Chief Counsel Thomas Kane said in transcribed congressional testimony that more IRS officials experienced computer crashes, bringing the total number of crash victims to “less than 20,” and also said that the agency does not know if the lost emails are still backed up somewhere.

The new round of computer crash victims includes David Fish, who routinely corresponded with Lois Lerner, as well as Lerner subordinate Andy Megosh, Lerner’s technical adviser Justin Lowe, and Cincinnati-based agent Kimberly Kitchens.

But hey, Lois Lerner says she did nothing wrong!

A question for Israel’s critics?

8:51 am

The article begins quite bluntly:

In light of the murderous actions and intentions of Hamas, what would you like Israel to do?

I wholeheartedly concur that the death of even one unarmed civilian is tragic, let alone the death of scores or of hundreds. And I affirm without hesitation that Arab blood is as precious as Jewish blood.

That being said, since Hamas is sworn to Israel’s destruction, since Hamas initiated the recent hostilities, since Hamas rejected cease fire offers, since Hamas is using civilians, including women and children, as human shields, and since Hamas is actively attempting to infiltrate Israel and murder, kidnap, and maim its people, what do you suggest that Israel does?

Read it all. It is an honest appraisal of the situation.

Was Yutu stopped by rough ground?

8:39 am

One of the designers of the Chinese lunar rover Yutu said in a news interview today that the rocky nature of the Moon’s surface, far rougher than expected, was what caused it to stall.

The rover was tested in Beijing, Shanghai and the desert in northwestern China before its launch, but the terrain of the landing site proved to be much more rugged than expected, said Zhang Yuhua, deputy chief designer of the lunar probe system for the Chang’e-3 mission. “It is almost like a gravel field.”

Data from foreign researchers projected that there would be four stones, each above 20 cm, on average every 100 square meters, but the quantity and size of the stones that Yutu has encountered has far exceeded this expectation, Zhang said in an exclusive interview with Xinhua. “Experts’ initial judgement for the abnormality of Yutu was that the rover was ‘wounded’ by colliding with stones while moving,” she said. [emphasis mine]

The implication of the highlighted quote is that it isn’t their fault, it was the fault of those evil Americans and Russians who incorrectly estimated the roughness of the ground. This article also doesn’t fit the information released when Yutu first stalled, where they explained that their problem was partly an inability to retract equipment in preparation for lunar night. While this story could be true, it isn’t the whole story.

Looking Forward

11:35 am

In the past week there must have been a hundred stories written celebrating the 45th anniversary of Apollo 11. Here’s just a small sampling:

These articles try to cover the topic from all angles. Some looked at the wonders of the achievement. Others extolled the newspaper’s local community and their contribution. Some used the event to demand the U.S. do it again.

None of this interests me much. Though I passionately want humans, preferable Americans, back on the Moon exploring and settling it, this fetish with celebrating Apollo is to me becoming quite tiresome.

The 707 turns 60

12:11 am

The sixtieth anniversary of Boeing’s 707 passenger jet and how it changed aviation history.

The pictures are cool, but read it for the history. Sixty years ago the ability of ordinary citizens to span the globe quickly and easily suddenly became possible, and that ability has changed the world.

More harrassment of opponents by the Obama administration

9:41 am

How the Obama Justice Department strong-arms banks to harass legal businesses it doesn’t like.

A Justice Department fraud prevention program came under fire Thursday for allegedly morphing into actively pressuring banks to deny financial services to businesses for political reasons.

Operation Choke Point functions as a partnership between the Department of Justice (DOJ) and various other federal agencies which deal with bank regulations, specifically the Treasury and the SEC. The objective of the project is to choke-off fraudulent businesses from accessing financial services, in an effort to protect consumers.

The controversy, however, is over allegations that the DOJ is pressuring financial institutions to decline doing business with so-called “high risk” industries which line up squarely against the political leanings of the current administration. These businesses include ammunition sales, payday loans, pornography, fireworks companies, and others—24 industries in total, as listed by the Federal Deposit Insurance Corporation (FDIC).

Much of the news today and yesterday has been about the Malaysian plane shot down over the Ukraine. Though Obama’s response was pitiful, I find this story above much more significant as it illustrates bluntly this administration’s strong misuse of power for political ends.

Caves on the Moon!

9:16 am

Scientists have now identified more than 200 cave pits on the Moon.

The pits range in size from about 5 meters (~5 yards) across to more than 900 meters (~984 yards) in diameter, and three of them were first identified using images from the Japanese Kaguya spacecraft. Hundreds more were found using a new computer algorithm that automatically scanned thousands of high-resolution images of the lunar surface from LRO’s Narrow Angle Camera (NAC).

This work is essentially the same as that done by James Fincannon and I back in 2011 (see links here, here, here, and here) but with much greater thoroughness.
