The unspoken contract

7:07 pm

Link here. Beautifully written, and encompasses very clearly why there is a growing revolt across America. The so-called elites are treating like scum the ordinary people that make their elite status possible, and the ordinary people are getting fed up with it.

People are tired. They’re just tired of constantly being told they’re racists when they have no idea what they’ve done wrong. They’re trying to keep the mortgage paid and get the kids through school and have enough money for Christmas presents and keep the cars out of the shop and lose that extra fifteen pounds and afford health insurance and maybe even take the family to a beach somewhere once a year. They love America, they love the flag, they support the troops and they are racking their brains to figure out what they can do to remedy the problem these rich, physical specimens seem to have with the country. If someone would just tell them what to do, most of them would gladly do it. But a blatant disrespect of something their grandpas and uncles and fathers and brothers fought and died for …is a breach of the unspoken contract.

Lockheed Martin unveils concepts for Mars ship and lander

2:36 pm

The boondoggle lobbying continues! Lockheed Martin today unveiled its concepts for a Mars interplanetary ship, built around its Orion capsule, as well as a fully reusable Mars lander.

The timing of this announcement fits perfectly with last week’s NASA announcement of its concepts for building a lunar space station, along with this week’s announcement to study doing it with the Russians. It also times perfectly with the announcement that the first public meeting of the National Space Council will take place on October 5. And tonight Elon Musk will give an update on his own proposals for getting to Mars.

All these public relations announcements suggest to me that the Trump administration is getting close to unveiling its own future space policy, and they all suggest that this policy will be to build a space station around the Moon. My guess is that Lockheed Martin and SpaceX are vying for a piece of that pie in their announcements today.

Let me also note that Lockheed Martin’s concept above illustrates nicely what a lie Orion is and has always been. They have been touting it for years as the vehicle that will get Americans to Mars, but now admit that it can only really be a small part of a much larger interplanetary ship, and will be there mostly to be the descent capsule when astronauts want to come home. They also admit in the video at the first link that their proposal for getting to Mars is only a concept. To build it would require many billions of dollars. I wonder will it cost as much as Orion and SLS ($43 billion plus) and take as long (18 years plus) to build? If so, it is a bad purchase. We can do this faster, and for less.

Sputnik full scale test model sells for $850K

2:15 pm

A full scale engineering test model of the Soviet Union’s Sputnik satellite sold at auction yesterday for $850K.

Bonhams auctioned the “beeping” replica of the now-iconic satellite, with its polished metal sphere and four protruding antennas, for $847,500 (including the premium charged to the buyer) at its New York gallery. The winning bid, placed by an unidentified buyer on the telephone, far surpassed the pre-auction estimate and the amount paid for a similar Sputnik replica sold by Bonhams for $269,000 in 2016.

Hubble spots most distance active comet yet

11:13 am

Comet C/2017 K2

Using the Hubble Space Telescope astronomers have imaged a comet that is sublimating material at a distance from the Sun farther than any previously known comet, out beyond Saturn.

“K2 is so far from the Sun and so cold, we know for sure that the activity — all the fuzzy stuff making it look like a comet — is not produced, as in other comets, by the evaporation of water ice,” said lead researcher David Jewitt of the University of California, Los Angeles. “Instead, we think the activity is due to the sublimation [a solid changing directly into a gas] of super-volatiles as K2 makes its maiden entry into the solar system’s planetary zone. That’s why it’s special. This comet is so far away and so incredibly cold that water ice there is frozen like a rock.”

Based on the Hubble observations of K2’s coma, Jewitt suggests that sunlight is heating frozen volatile gases – such as oxygen, nitrogen, carbon dioxide, and carbon monoxide – that coat the comet’s frigid surface. These icy volatiles lift off from the comet and release dust, forming the coma. Past studies of the composition of comets near the Sun have revealed the same mixture of volatile ices.

The significance here is that by studying the comet’s activity scientists will be able to identify some of these volatile gases, which in turn will tell them something about the make-up of the outermost fringes of the solar system.

Status of Arecibo radio observatory

9:16 am

It appears that, while Puerto Rico itself suffered devastating damage from Hurricane Maria, the Arecibo Observatory came through relatively unscathed.

The surface of the dish was largely unscathed, and the observatory’s most vulnerable component, the instrument platform suspended high above the dish by cables strung from three towers, each more than 80 meters tall, was still in place and seemed undamaged, says Schmelz. She is based at the Columbia, Maryland, headquarters of one of Arecibo’s operators, the Universities Space Research Association, and spoke with staff in Puerto Rico who first used a ham radio and then a single working satellite phone. But the roofs on some observatory buildings were blown off, the sinkhole under the dish was flooded, and other equipment was damaged by rain and fallen trees. Most significantly, a large portion of a 29-meter-long antenna—the 430-megahertz line feed used for studying the upper atmosphere—appears to have broken off and fallen from the platform into the dish. Mathews estimates a bill of several million dollars to replace the line feed alone.

Because of the significant infrastructure damage across the island, there will be significant delays in getting any of this fixed. Since the telescope is already being considered for shut down due to budget issues, these delays could lead to that shut down.

Chinese government orders shutdown of all North Korean businesses

8:39 am

The Chinese government has ordered that all businesses run by North Koreans, whether singly or in a joint partnership, must shut down within the next four months.

The order applies to all such businesses in China, as well as any Chinese/North Korean joint ventures abroad. It will exempt nonprofits and “noncommercial infrastructure projects,” whatever that is, and will also allow individual businesses to request a waiver.

One last image from Rosetta

8:17 am

Rosetta's last image

Engineers reviewing the last bits of telemetry that was transmitted back to Earth by Rosetta just before it crashed on Comet 67P/C-G have discovered one last image of the comet’s surface.

That image is on the right. It is slightly blurred because of the limitations of Rosetta’s camera at this short range, and the incompleteness of the data received.

The image covers an area about a meter across, with a resolution of about two millimeters per pixel.

I imagine this surface is relatively soft, since the gravity holding the comet together is so slight. If you wanted to dig down, you would find it easy digging.
