Boston mayor wants doctors to grill patients about guns

9:52 am

They’re coming for you next: Boston’s liberal mayor want to require doctors to ask patients if they own guns and then lecture them about gun safety.

This act would require medical professionals to ask patients about guns in the home, and bring up the topics of gun safety. The goal, Boston Police Commissioner William Gross said, is to identify those at risk for domestic violence, suicide or child access to guns in order to guide people to mental health counseling, resources or other help. “We’re just asking them to help identify ways to save lives,” Gross said.

The fact that a patient owns guns would not be put in their medical record, and is not intended to have physicians help solve crimes.

If my doctor asked me this, I would tell him to jump in a lake. It is none of his business. However, this is clearly aimed at raising the social cost of gun ownership by making society more hostile to it. The next step would be to demand this data be recorded, which would then provide the government a list of gun owners that they can target.

Summer has finally arrived on Titan’s northern hemisphere

9:42 am

The uncertainty of science: In a review of Cassini data from 2016, scientists have finally identified rain in the northern polar regions of Titan, signaling the onset of summer there.

The whole Titan community has been looking forward to seeing clouds and rains on Titan’s north pole, indicating the start of the northern summer, but despite what the climate models had predicted, we weren’t even seeing any clouds,” said Rajani Dhingra, a doctoral student in physics at the University of Idaho in Moscow, and lead author of the new study accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union. “People called it the curious case of missing clouds.”

Dhingra and her colleagues identified a reflective feature near Titan’s north pole on an image taken June 7, 2016, by Cassini’s near-infrared instrument, the Visual and Infrared Mapping Spectrometer. The reflective feature covered approximately 46,332 square miles, roughly half the size of the Great Lakes, and did not appear on images from previous and subsequent Cassini passes.

Analyses of the short-term reflective feature suggested it likely resulted from sunlight reflecting off a wet surface. The study attributes the reflection to a methane rainfall event, followed by a probable period of evaporation. “It’s like looking at a sunlit wet sidewalk,” Dhingra said.

Though the data somewhat matches their climate models, those models did not predict the rain’s late arrival, which means they need revision. I guarantee that this will not be the last revision, though without an orbiter at Saturn it will probably be decades before we have new data to make that possible.

Shake-up at half billion dollar government ecology project

9:24 am

Even as the government shutdown continues, the contractor managing a $434 million ecology project has dismissed two project managers and dissolved a 20-member scientific advisory board.

The turmoil is the latest in a long line of woes for NEON, which launched in 2000 and has faced ballooning budgets and allegations of mismanagement by its previous operator. Battelle took over NEON’s operations in 2016 and, in 2018, appointed Collinge, an environmental scientist at the University of Colorado Boulder, as the network’s observatory director and chief scientist. The non-profit also created the 20-member Science, Technology & Education Advisory Committee (STEAC) to advise NEON.

STEAC members credit Battelle with saving NEON, and construction of its observatories is now on schedule. But several see the dismissals and cancellation of the board as a breach of trust with the scientists who hope to use NEON data. “That’s burning bridges, which you just can’t afford to do in a small community,” says Ankur Desai, an atmospheric scientist at the University of Wisconsin–Madison.

“I understand fully that this is very difficult and emotional for some people,” says Battelle spokesperson Patrick Jarvis. “Our goal remains to develop amazing data products and help the research community understand what’s going on at the broadest ecological level.”

The article includes a lot of whining by scientists about this, but I wonder. I also wonder at this project’s real scientific value. It could be legitimate, with the contractor merely cleaning house to make it run better. Or maybe it’s a boondoggle that is aimed solely at confirming the politically-driven environmental theories of the green activist community. If I had to guess, based on the track record of most big government projects these days, I’d pick the latter.

Argentinian smallsat company signs 90 satellite deal with China

9:14 am

An Argentinian smallsat company, Satellogic, has signed a 90 satellite launch deal with China.

Satellogic’s constellation seems likely to compete with the remote-imaging satellite constellations operated by San Francisco-based Planet and Seattle-based BlackSky. The company promises to remap Earth at 1-meter pixel resolution every week and dramatically reduce the cost of high-frequency geospatial analytics.

The deal is officially signed with a so-called private launch company in China dubbed China Great Wall Industry, but that company merely acts as an agent for a Chinese government space operation, China Aerospace Science and Technology Corp.

What this means however is that China’s launch rate is going to go even higher in the next few years.

A detailed look at the layoffs at SpaceX

9:07 am

Capitalism in space: Link here. Because of California’s complex employee protection laws, SpaceX has provided the government there a detailed list describing the 577 layoffs taking place in California.

Technicians — a critical role at any rocket company — make up the lion’s share of laid-off employees, with 174 positions eliminated (30.2% of all layoffs in Hawthorne). Engineers come next with 97 jobs let go, or nearly 17% of the locally terminated workforce.

Managers and supervisors together make up about 7% of the layoffs in Hawthorne. Positions listed under “Other” include baristas, dishwashers, drivers, recruiters, writers, and an investigator.

The article really doesn’t tell us much, other than the large majority of the 10% reduction are occurring in California, which makes me wonder if SpaceX is acting to reduce its presence in that high-tax, high-regulation state.

Arianespace plans at least 12 launches in 2019

8:59 am

Capitalism in space: The head of Arianespace today announced that it plans at least 12 launches in 2019.

Stéphane Israël, CEO of Evry, France-based Arianespace, said the company has four launches of the light-lift Vega rocket planned for this year, plus the maiden flight of the next-generation Vega C.

Arianespace’s first mission of the year is an Ariane 5 launch on Feb. 5. The rocket will carry two satellites — Arabsat’s Saudi GeoSat-1/Hellas Sat-4 and the Indian space agency ISRO’s GSAT-31 — to geostationary transfer orbit. All five Ariane 5 missions planned for this year will carry two satellites, as is customary, Israël said in an interview.

Israël said Arianespace has three firm Soyuz launches on its 2019 manifest, starting mid-February with the launch of 10 small telecom satellites for internet megaconstellation startup OneWeb.

Israël actually lists thirteen launches here, so I am not sure why the article sets the number at twelve. This number is only two more than my initial estimate based on scheduled launches listed here.

Update on Chang’e-4 plant experiments

5:32 pm

Link here. It appears the plant experiment has now run its course, designed as it was to end before the arrival of the first lunar night.

The experiment’s chief designer, Xie Gengxin of Chongqing University, told Xinhua that life inside the canister would not survive the lander’s first lunar night, which started on Sunday. The moon’s nighttime period lasts for about two Earth weeks.

It also appears that though the plant experiment included potato, cotton, and oilseed rape, only the cotton seeds spouted. China has only released a limited amount of information about this research, so to get further details we will likely have to wait for the published papers.

More updates from SpaceX’s Boca Chica launch site

9:16 am

Link here. The article reviews what has been done for the past few months, as well as what has been done most recently. All of this new work appears focused on preparing for test flights of Starship and Super Heavy.

I should note however that I am beginning to sense a little bit of Barnum in this work. The steel-clad Starship Hopper that SpaceX has assembled here is clearly not even close to doing any hopper tests, as it doesn’t appear to have fuel tanks and its engines appear to be mere “placeholders for fit checks.” It looks really really cool, however, and is impossible to hide to the public, so it thus has garnered the company a lot of attention.

Seeds sprout on Chang’e-4

9:01 am

The new colonial movement: The cotten seeds in a plant experiment on Chang’e-4 have now sprouted, becoming the first biological life to grow on the Moon.

On Tuesday, Chinese state media said the cotton seeds had now grown buds. The ruling Communist Party’s official mouthpiece the People’s Daily tweeted an image of the sprouted seed, saying it marked “the completion of humankind’s first biological experiment on the Moon”.

Fred Watson, Australian Astronomical Observatory’s astronomer-at-large, told the BBC the development was “good news”. “It suggests that there might not be insurmountable problems for astronauts in future trying to grow their own crops on the moon in a controlled environment. …I think there’s certainly a great deal of interest in using the Moon as staging post, particularly for flights to Mars, because it’s relatively near the Earth,” Mr Watson said.

Prof Xie Gengxin, the experiment’s chief designer, was quoted as saying in the South China Morning Post: “We have given consideration to future survival in space. Learning about these plants’ growth in a low-gravity environment would allow us to lay the foundation for our future establishment of space base.” He said cotton could eventually be used for clothing while the potatoes could be a food source for astronauts and the rapeseed for oil.

This experiment is actually a very big deal, as it is the first biological experiment, ever, to take place in a low gravity environment. All previous plant experiments in space have taken place in zero gravity, and thus failed to tell us anything about growth in a partial Earth gravity environment.

That the seeds have sprouted only tells us that they can. What we don’t know yet is if the low lunar gravity distorts their growth.

Iran rocket fails to place satellite in orbit

8:44 am

The new colonial movement: According to their government sources, Iran today tried and failed to place a Earth imaging satellite into orbit with their Simorgh rocket.

The rocket carrying the Payam satellite failed to reach the “necessary speed” in the third stage of its launch, Telecommunications Minister Mohammad Javad Azari Jahromi said.

Jahromi said the rocket had successfully passed its first and second stages before developing problems in the third. He didn’t elaborate on what caused the rocket failure but promised that Iranian scientists would continue their work.

I wonder how much of a failure this launch is. If they were testing an ICBM capability, then the successful operation of the first and second stages would likely rank this as a success. And even if their main goal wasn’t ICBM testing, in the end they have done so, as they can apply what they learn here to all military missile technology.

Update: You can see video of the launch at this Iranian press story, along with other details about Iran’s space effort. I found the comments there most educational however. Here’s one sample: “Iran needs to use its space technology to fire invincible hyper-sonic missiles from space at the Jews in Israel.” The comments are all not like this, but there are enough to give you a sense of Iran’s social culture.
