Abraham Lincoln – a tribute on his birthday

6:01 pm

An evening pause: As today is Abraham Lincoln’s birthday, I feel compelled to repost my Lincoln tribute from last year. Above all, it is necessary we remember again the amazing good will he repeatedly expressed, even to those who hated him and wished to kill him. As I said last year:

We should also remind ourselves, especially in this time of increasing anger, bigotry, and violence, of these words from his second inaugural address, spoken in the final days of a violent war that had pitted brother against brother in order to set other men free:

Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman’s two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said “the judgments of the Lord are true and righteous altogether.”

With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation’s wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.

The first music video in zero gravity

10:30 am

Update: The music video itself has been pulled from youtube for copyright reasons that I don’t quite understand. However, the making of video is still available, and that will give you a pretty good feel for some of the stuff in the original piece.

I was going to make this an evening pause, but then decided it shouldn’t wait. This music video, by OK-Go, is unique and somewhat historic, as it I think is the first to have been done in zero gravity, using an airplane to fly parabolic arcs. It demonstrates clearly the fantastic and as present almost unimaginable possibilities of dance in weightlessness, as it also might be the first time that professional dancers, the two women, are given a chance to do moves in microgravity.

Be sure to also watch the making of video below the fold. And go here for the story behind the video.

SpaceX loses a launch payload

10:11 am

In the heat of competition: Because of delays, a satellite company has shifted its launch vehicle from SpaceX’s Falcon Heavy to Arianespace’s Ariane 5

The company, ViaSat, still has a contract with SpaceX to use Falcon Heavy to launch later satellites, but they decided they could no longer wait and needed to get the satellite in orbit by 2017, something that SpaceX could no longer guarantee. They had to pay more to fly on Ariane 5, but it appears they were able to negotiate a price break with Arianespace to close the deal.

Big solar storm not so big

10:01 am

The uncertainty of science: A new analysis of the the 1859 giant solar storm, the first ever detected and dubbed the Carrington event after the scientist who discovered it, suggests that its strength was not global as previously believed, and that it only effected a few spots on Earth.

Up until now the Carrington event has been considered the strongest solar storm to ever hit the Earth, and has been used by the solar satellite industry as a wedge to demand funding for solar warning satellites, claiming that if a similar storm was to ever hit the Earth again without warning, it would destroy civilization as we know it. This new data suggests that this threat has been over-stated.

Why am I not surprised?

Tests confirm meteorite at India impact site

9:53 am

The uncertainty of science: Even as NASA officials poo-poo the suspected meteorite impact in India that killed a bus driver, India scientists have done a chemical analysis of one of the rocks found near the site and found it to be a meteorite fragment.

According to a preliminary report by National College Instrumentation Facility (NCIF) in Trichy, a Scanning Electron Microscope (SEM) study on samples retrieved from the campus in Vellore where the blast occurred shows the “presence of carbonaceous chondrites”.

“Carbonaceous denotes objects containing carbon or its compounds and chondrites refer to non-metallic meteorite parts containing mineral granules,” K Anbarasu, a geologist who is also principal of the Trichy-based National College, told The Indian Express.

There remains uncertainty because the fragments tested did not actually come from the impact crater itself.

Anbarasu said the preliminary SEM study was conducted on “small pieces of black material” found near the blast site. “The crater formed at the spot had been already disturbed by other investigators. So we inspected the entire campus as any meteor incident would scatter several objects across the area before landing. Finally, we spotted several small pieces of this black material, one the size of a paperweight, on the terrace of a building nearby,” Anbarasu said.

Nonetheless, I think it unprofessional and inappropriate for a NASA official to comment on this event half a globe away. There is no way that they can really determine anything from the available photos taken of the impact site, and thus they should shut up.

The graffiti inside Apollo 11

9:39 am

An effort to create a 3D model of the inside of the Apollo 11 capsule on display at the National Air & Space Museum has revealed previously undocumented notes and scribbles that the astronauts put on the capsule’s walls.

Needell and his team also decided that they would provide access to the lower equipment bay, the area located below the astronauts’ seats, which housed the ship’s navigation sextant, telescope and computer. “No one from the Smithsonian, as far I knew — not as long as I’ve been the curator for 20 years, has ever been below there to document the conditions or any of the aspects of the lower equipment bay,” said Needell. “We’ve been able to sort of see above the seats, but that’s about all.”

So, for the first time, the curators removed from the lower bay the large bag that held the Apollo 11 crew’s pressure garment assemblies — in other words, their spacesuits — as well as several helmet bags and a checklist pocket that command module pilot Michael Collins used while orbiting the moon alone.

And then they saw it, the literal writing on the wall.

They have located at least one post-landing image that shows some of the writing, which indicates that in 1969 no one considered this important enough to note. Then the capsule was put on display, and no one was allowed in it for decades.

The final search for Philae

8:57 am

This review of the journey of Rosetta’s lander Philae, now dead on the surface of Comet 67P/C-G, includes information about the science’s team upcoming last effort to locate the lander.

The comet’s level of activity is now decreasing, allowing Rosetta to safely and gradually reduce its distance to the comet again,” says Sylvain Lodiot, ESA’s Rosetta spacecraft operations manager. “Eventually we will be able to fly in ‘bound orbits’ again, approaching to within 10–20 km – and even closer in the final stages of the mission – putting us in a position to fly above Abydos close enough to obtain dedicated high-resolution images to finally locate Philae and understand its attitude and orientation.”

“Determining Philae’s location would also allow us to better understand the context of the incredible in situ measurements already collected, enabling us to extract even more valuable science from the data,” says Matt Taylor, ESA’s Rosetta project scientist.

They intend to try to re-establish communications with the lander, but do not have much expectations that it is able to function.

The politics of high fantasy

12:19 am

Link here.

Beyond railing against the wreckage, the other commonality between the two big New Hampshire winners is in the nature of the cure they offer. Let the others propose carefully budgeted five-point plans. Sanders and Trump offer magic.

Take Sanders’ New Hampshire victory speech. It promised the moon: college education, free; universal health care, free; world peace, also free because we won’t be “the policeman of the world” (mythical Sunni armies will presumably be doing that for us). Plus a guaranteed $15 minimum wage. All to be achieved by taxing the rich. Who can be against a “speculation” tax (whatever that means)?

So with Trump. Leave it to him. Jobs will flow back in a rush from China, from Japan, from Mexico, from everywhere. Universal health care, with Obamacare replaced by “something terrific.” Veterans finally taken care of. Drugs stopped cold at the border. Indeed, an end to drug addiction itself. Victory upon victory of every kind.

How? That question never comes up anymore. No one expects an answer. His will be done, on Earth if not yet in heaven. Yes, people love Trump’s contempt for the “establishment” — which as far as I can tell means anything not Trump — but what is truly thrilling is the promise of a near-biblical restoration. As painless as Sanders’.

I would say that this above all is my biggest problem with Trump. As good a deal maker as he claims he is, he really seems to have a very childish and naive understanding of what he’ll be able to do once in the White House. Worse, he might very well decide that following the Constitution is too much of a bother, and that though he might think that Obama had the right idea to chew hard at its limits along the edges, maybe it would be better if President Trump tore it apart with his teeth.

Even more frightening to me is the apparent naive belief the electorate seems to have in these pie-in-the-sky promises. Our civilized society cannot stand if our citizenry has become so muddled-brained that it sees these promises as realistic.

TMT might abandon Hawaii

9:10 pm

The consortium building the Thirty Meter Telescope (TMT) decided last week that, because of the delays forced on them by protesters in Hawaii, they are going to start identifying alternative locations.

I don’t think they have a choice. They want to start construction no later than 2018, which already involves a three year delay from their original schedule and significant additional costs. I doubt there is any chance that the permit process, which took years the first time they did it, can take anywhere close to that.
