Very brief descriptions, with appropriate links, of current or recent news items.
We are doomed: A new poll finds that the public opposes cuts to virtually all types of spending.
We can make believe we can keep spending as we have, but reality always wins.
The Falcon 9 static fire test is now set for Monday.
I’m not sure if this is a reschedule, or the information I posted from previous stories was incorrect. Either way, this test is their standard preparation for Falcon 9’s next launch.
Finding out what’s in it: Because of the cost of Obamacare, employers are dropping healthcare coverage for spouses.
By denying coverage to spouses, employers not only save the annual premiums, but also the new fees that went into effect as part of the Affordable Care Act. This year, companies have to pay $1 or $2 “per life” covered on their plans, a sum that jumps to $65 in 2014. And health law guidelines proposed recently mandate coverage of employees’ dependent children (up to age 26), but husbands and wives are optional.
Chicken Little report: The head of the Transportation Department today threatened long delays if the sequestration cuts take place March 1.
Either he is lying or he has decided to make the most harmful cuts to hurt the public the most. Sequestration will lower the budget of the FAA by 8.2 percent, which will cut that agency’s budget from $18.7 to $17.2 billion, which is still more than the FAA got in 2009, by $300 million. I don’t remember long delays and limited airport operations at that time, do you? See here for my sources.
There is no reason to shut down operations or cause significant travel delays, unless LaHood wants to cause pain so that the money flow keeps pouring in.
Update: One more comment. It took me all of five minutes of research to come up with the past budgets of the FAA to give the sequestration cuts some context. I think it disgraceful that the reporter for this story couldn’t do the same.
The competition heats up: An update on Boeing’s CST-100 capsule.
The day of reckoning looms: A new U.N. report states that Iran has moved another step closer to building its own nuclear weapon.
R.I.P. Dr. David S. McKay: 1936-2013. More here.
Though he was most famous for being the lead author of the 1996 paper suggesting that fossil life had found in a Martian meteorite, McKay was one of the giants of planetary science whose work was far more extensive and important. He will be missed.
New data has allowed scientists to lower the chance that the asteroid Apophis will hit the Earth in a future orbit.
Recent observations from Pan-STARRS PS1 telescope at Haleakala, Hawaii have reduced the current orbital uncertainty by a factor of 5, and radar observations in early 2013 from Goldstone and Arecibo will further improve the knowledge of Apophis’ current position. However, the current knowledge is now precise enough that the uncertainty in predicting the position in 2029 is completely dominated by the so-called Yarkovsky effect, a subtle nongravitational perturbation due to thermal re-radiation of solar energy absorbed by the asteroid. The Yarkovsky effect depends on the asteroid’s size, mass, thermal properties, and critically on the orientation of the asteroid’s spin axis, which is currently unknown. This means that predictions for the 2029 Earth encounter will not improve significantly until these physical and spin characteristics are better determined.
The new report, which does not make use of the 2013 radar measurements, identifies over a dozen keyholes that fall within the range of possible 2029 encounter distances. Notably, the potential impact in 2036 that had previously held the highest probability has been effectively ruled out since its probability has fallen to well below one chance in one million. Indeed only one of the potential impacts has a probability of impact greater than 1-in-a-million; there is a 2-meter wide keyhole that leads to an impact in 2068, with impact odds of about 2.3 in a million.
The second paragraph basically says that the keyholes that might bring Apophis back to Earth are very small, making it unlikely that the asteroid will fly through any one of them in 2029. The first paragraph however notes that it will be impossible to chart the asteroid’s course accurately enough to rule out this possibility until we have more data on the asteroid itself.
Consensus! In an interview in Australia, the head of the IPCC has admitted that the climate has stopped warming now for the past seventeen years.
No computer climate model offered in any IPCC report predicted this long pause in warming. They all instead insisted that because of the increase of carbon dioxide in the atmosphere, the global temperature would have to rise, and do so quickly and with catastrophic results.
In other words, those models were wrong. The climate is very complicated, and we don’t yet understand very well how it functions.
How to see Comet PANSTARRS, expected to be visible to the naked eye in the evening sky in March.
Using Kepler astronomers have discovered a three planet solar system with one planet slightly larger than our Moon.
Kepler-37’s host star belongs to the same class as our sun, although it is slightly cooler and smaller. All three planets orbit the star at less than the distance Mercury is to the sun, suggesting they are very hot, inhospitable worlds. [The moon-sized] Kepler-37b orbits every 13 days at less than one-third Mercury’s distance from the sun. The estimated surface temperature of this smoldering planet, at more than 800 degrees Fahrenheit (700 degrees Kelvin), would be hot enough to melt the zinc in a penny. Kepler-37c and Kepler-37d, orbit every 21 days and 40 days, respectively.
Doesn’t this make you feel safer? The TSA detained a wheelchair-bound three-year-old girl, took away her stuffed doll, and refused to allow the parents to videotape the child’s pat down. Videotape at the link.
It is necessary for more people to challenge these thugs. (I don’t care that the agents in the video tried to be polite to the mother, they were still acting like brainless thugs.)
In an effort to save money and protect the environment, the U.S. Navy has decided to move away from fossil fuels and back to non-toxic and environmentally friendly wind power.
Not letting Republican obstructionism of the budget process go to waste, President Obama’s national defense team is putting together a plan to retrofit US warship with ‘tried-and-true’ sails, taking advantage of free, naturally occurring wind rather than diesel and nuclear fuels that put crews at constant risk of causing an ecological disaster.
Used by many advanced cultures for thousands of years, sails were the environmentally sound propulsion system for naval vessels until the 20th century.
Many experts agree that their return might just usher in a new era of ‘green military technology’ – if it can overcome opposition from the generals and the fossil fuels lobby, whose alleged “concerns” about military readiness only serve to ensure more profits for the military-industrial complex.
Read the whole thing. It makes perfect sense!
The anti-choice left’s disarming of the American woman.
As I said, the fascists are out, and they appear no longer timid about telling us who they are and how they want to control our lives.
The competition heats up: There will be hot fire tests on Friday of both the Antares and Falcon 9 rockets.
The microfilmed miniature bibles that flew to the moon during Apollo have become the center of a custody dispute between the state of Texas and the author who wrote their history.
Scientists have released some results, including video, from their look at asteroid 2012 DA14 during its fly-by last week. Key quote:
The asteroid’s path was perturbed by Earth’s gravitational field in such a way that it won’t come as close in the foreseeable future.
The video, which I have embeded below the fold, was produced from radar data. It clearly shows the asteroid’s rotation.

Consensus! A new poll of Earth scientists has found that a majority are skeptical of human-caused global warming.
Only 36 percent of geoscientists and engineers believe that humans are creating a global warming crisis, according to a survey reported in the peer-reviewed Organization Studies. By contrast, a strong majority of the 1,077 respondents believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem.
This is fun to note, but this poll is as worthless in determining the climate of the Earth as every previous poll that said the opposite. What matters is the data. However, this quote about the poll is significant:

After a three hour outage NASA has regained communications with ISS.
Not fit to print: Two days ago the Congressional Budget Office increased its projection for the cost of Obamacare by 29 percent, while also saying that seven million workers will lose their health insurance due to the law, almost twice as many as previously estimated.
As noted at the link, not one news organization has seen fit to mention this juicy tidbit in their news reports. I wonder why?
Meanwhile, we will go bankrupt. This law, and the government that is imposing it on us, is unsustainable.
NASA mission control in Houston has lost all communications with ISS.
Communications are still possible each orbit for short periods with Moscow.
The hotfire test of Antares’ first stage has been rescheduled for Thursday, February 21.
Some thoughts by Alan Stern on a better way to name exoplanets.
The fascists are out: A gun control bill introduced in the state of Washington includes a provision that allows the police to conduct yearly house searches, without a warrant, of any gun owner’s home.
Such searches would violate the fourth amendment of the Constitution, and in my case, any cop who showed up at my door would be politely told that I do not consent to any searches, without a warrant. They don’t get in my door.
Meanwhile, the Democrats who sponsored this bill, without reading it of course, are now tripping over themselves to disavow it, as if that would somehow make everyone forget that they introduced it.
The abandoned calibration targets used by surveillance satellites of the 1960s.
“There are dozens of aerial photo calibration targets across the USA,” the Center for Land Use Interpretation reports, “curious land-based two-dimensional optical artifacts used for the development of aerial photography and aircraft. They were made mostly in the 1950s and 1960s, though some apparently later than that, and many are still in use, though their history is obscure.”
“Doomsday never arrived, apparently.”
The topic isn’t meteorites, but something more critical to our survival as a society.
Mercury, in full color.
Scientists working with NASA’s Messenger probe have produced a global color map of the surface of Mercury, closest planet to the Sun. Thousands of sets of images were enhanced then stitched together in a mosaic to create a detailed image covering the entire planet.
Russian scientists have identified the first fragments from Friday’s meteorite in Chelyabinsk.
The pieces, found on the ice of a lake, were stony chondrites.
