Republicans and Democrats fight to restrict freedoms
Ugh: House Republicans move to introduce new gun control law, House Democrats vow to fight it because it will allow for due process.
From the second link:
A Democratic source said the more controversial gun-purchase provision may be similar to a bill sponsored by Sen. John Cornyn (R-Texas) that’s backed by the National Rifle Association. Democrats say the Cornyn bill doesn’t go far enough since it includes a “probable cause” standard that would require law enforcement officials to prove that a gun buyer is an actual terrorist rather than a suspected terrorist. Instead, Democrats want a vote on legislation that would bar firearm sales to anyone on a terrorism watch list or no-fly list.
Without a vote on their own legislation, Rep. John Lewis (D-Ga.) and other Democrats have threatened to take control of the House floor once again after they return from the Fourth of July recess. On Wednesday, Minority Leader Nancy Pelosi (D-Calif.) and dozens of other Democrats held events around the country demanding action to stop gun violence.
It is disgusting how Democrats no longer support the idea of due process, that they are cool with the idea of secret lists that can deny any American his or her constitutional rights. Boy will they squeal when those lists are used to deny them their rights!
However, it is just as disgusting that the Republicans are playing into the Democrats hands here by introducing any gun control legislation. This is not how you fight Islamic terrorism, by denying Americans access to guns. You fight Islamic terrorism by standing up for our rights while aggressively going after the terrorists who commit those acts of violence.
Space reporter banned from space news website
Petty fascism: Doug Messier, who runs the excellent space news website Parabolic Arc, which I link to periodically, has been banned from posting comments on another generally excellent space news website, NASASpaceflight.com
To quote his website:
I just got banned from the NasaSpaceflight forums with this little message from little Andy.
“Sorry parabolicarc, you are banned from using this forum! Please use your own site to post what your “sources” are telling you. Too many people are sick of you using this site to spread rumors. Andy.
This ban is not set to expire.”
Doug is also the reporter with whom I and many other commenters at Behind the Black had a long, passioned but intelligent debate about global warming. As much as I might disagree with him on that subject, I find it baffling that any space website would ban him from commenting, especially since his reporting on space has been impeccably accurate and hard-hitting.
In a sense, this ban is just another example of how too many Americans can no longer deal with debate and opposing points of view. Very sad. Doug of course is always welcome to comment here, even when he strongly disagrees with what I’ve written.
Hubble images Jupiter and its aurora
Cool image time! In anticipation of the arrival of Juno in orbit around Jupiter on July 4, scientists have released a spectacular image of Jupiter and its aurora, taken by the Hubble Space Telescope. The image on the right has been reduced slightly to fit on the webpage.
The main focus of the imaging is the aurora.
To highlight changes in the auroras, Hubble is observing Jupiter almost daily for several months. Using this series of far-ultraviolet images from Hubble’s Space Telescope Imaging Spectrograph, it is possible for scientists to create videos that demonstrate the movement of the vivid auroras, which cover areas bigger than the Earth.
Not only are the auroras huge in size, they are also hundreds of times more energetic than auroras on Earth. And, unlike those on Earth, they never cease. While on Earth the most intense auroras are caused by solar storms — when charged particles rain down on the upper atmosphere, excite gases, and cause them to glow red, green, and purple — Jupiter has an additional source for its auroras.
The strong magnetic field of the gas giant grabs charged particles from its surroundings. This includes not only the charged particles within the solar wind, but also the particles thrown into space by its orbiting moon Io, known for its numerous and large volcanos.
I have embedded below the fold one of the videos of the aurora, taken over time by Hubble. Quite amazing.

Airbus Safran merger completed
The competition heats up: The expected merger of Airbus and Safran to create a rocket company called Airbus Safran Launchers is expected to be finalized today, allowing the new company to move forward in its construction of Ariane 6, designed to compete with SpaceX’s lower cost rockets.
Rosetta’s finale set for September 30
The Rosetta science team has set September 30th as the date when they will complete the spacecraft’s mission with a controlled descent onto Comet 67P/C-G’s surface.
Unlike in 2011, when Rosetta was put into a 31-month hibernation for the most distant part of its journey, this time it is riding alongside the comet. Comet 67P/Churyumov-Gerasimenko’s maximum distance from the Sun (over 850 million km) is more than Rosetta has ever journeyed before. The result is that there is not enough power at its most distant point to guarantee that Rosetta’s heaters would be able to keep it warm enough to survive.
Instead of risking a much longer hibernation that is unlikely to be survivable, and after consultation with Rosetta’s science team in 2014, it was decided that Rosetta would follow its lander Philae down onto the comet. The final hours of descent will enable Rosetta to make many once-in-a-lifetime measurements, including very-high-resolution imaging, boosting Rosetta’s science return with precious close-up data achievable only through such a unique conclusion. Communications will cease, however, once the orbiter reaches the surface, and its operations will then end.
The decision to end the mission this way makes great sense. I only question their decision to purposely end all communications upon impact. Though it is likely that communications will be lost anyway, wouldn’t it be better to try to get data back, like the scientists did with the American NEAR spacecraft when it touched down on the asteroid Eros at the end of its mission?
Our limited understanding of the Martian climate through time
The uncertainty of science: Annual Reviews periodically publishes papers providing a detailed scientific review of the present state of knowledge in a variety of fields. They do this by collecting the papers in volumes focused on general areas of research, such as Astronomy and Astrophysics, Plant Biology, and even Sociology.
Today I received the announcement of the publication of the 44th volume of the Annual Review of Earth and Planetary Sciences, listing the volume’s table of contents. While there were many interesting papers on a variety of planetary subjects that interested me (“The climate of Titan,” “Impacts of Climate Change on the Collapse of Lowland Maya Civilization,” and “The Lakes and Seas of Titan”), one paper in particular, entitled “The climate of early Mars”, intrigued me enough after reading the abstract to download it and read it in its entirely. (As a science journalist I have free access to the full text of these papers. While the abstract is free to all, if you wish to read the full text you need to either buy it, or visit a university library that subscribes to each particular series.)
As a review I found the paper quite fascinating. It provided an excellent overview of our present understanding of Mars’s climate history, information that is especially useful to me in reporting on the results from the various Martian orbiters and rovers, as it gives me a wider context and allows me to better understand and analyze each press announcement. This in turn allows me to distinguish between a real discovery of some importance and a garbage press release that is really nothing more than a sales pitch for more funding.
The bottom line of this paper however is this: We know without doubt, based on a lot of geological evidence, that approximately 3 to 4 billion years ago liquid water existed on the Martian surface, leaving behind complex valley drainage networks similar to those created by flowing water on Earth. In addition, the data from the rovers has also found evidence, clays and other minerals, that could only have formed if water once flowed on the surface. What we don’t know is how that liquid water could have existed. The data so far does not provide any clear mechanism for warming the climate enough as well as producing a thick enough atmosphere to allow liquid water to flow. To quote the paper:
In summary, no single mechanism is currently accepted as the cause of anomalous warming events on early Mars.
The data also suggests that an ocean on Mars was unlikely, though not impossible. Instead, it appears that if any warming events occurred to produce liquid water, they were temporary and short-lived. What caused those warming events, however, remains a scientific mystery.
The paper also made clear once again the complexity of climate science, and how difficult it is to develop climate models that explain the geological evidence, not just on Mars, but on Earth as well. As the paper also noted, “Just like the climate of Earth today, the ancient climate of Mars was probably complex, with multiple factors contributing to the mean surface temperature.” And like the climate of Earth, many of those multiple factors remain uncertain and poorly understood. It will be many years before we really understand how Mars got to be the way it is.
Likely, to figure it out we will have to go there ourselves and poke around with our own hands.

New evidence that Lois Lerner released confidential taxpayer information illegally
Working for the Democratic Party: In her effort at the IRS to harass conservatives and anyone opposing the Democratic Party, newly released documents now suggest that Lois Lerner broke the law when she provided more than a million pages of confidential taxpayer information in 2010 to the Obama Justice Department.
Hmm. The Democratic Party calls for the nullification of the first, second, and fifth amendments of the Bill of Rights. Its allies in the IRS and Justice Department team up to illegally access confidential tax records of their opponents, for the purpose of possibly prosecuting those opponents. Furthermore, this same party is advocating the prosecution of companies who disagree with them on the subject of global warming.
Seems there might be a pattern here. Seems this political party is hell bent on oppressing those who oppose it. Seems this behavior is kind of like the behavior of the fascists in Europe in the 1930s. Maybe that suggests they might have a lot in common?
Nah, can’t be true. They care about us, and that’s all that matters!
Oakland city council micromanages the shipping industry
Fascist California: The Oakland city council has voted to block coal shipments through its brand new marine terminal.
The Oakland city council voted unanimously to bar shipments of coal through a proposed marine terminal on Monday, setting the stage for a legal battle.
The prospect of train cars carrying millions of tons of coal mined in Utah through Oakland before heading to Asian markets has inflamed passions in the city. Opponents argue it will harm health and exacerbate climate change. Proponents say it will provide good jobs in an impoverished area.
And I say it is none of the damn business of these petty dictators to decide what and where stuff gets shipped, especially if it is legal product.
Dawn data suggests recent hydrothermal activity on Ceres
New data from Dawn now suggests that the bright spot in Occator Crater on Ceres contains the highest concentration of carbonate materials found so far outside of Earth, and was caused by recent hydrothermal activity.
De Sanctis’ study finds that the dominant mineral of this bright area is sodium carbonate, a kind of salt found on Earth in hydrothermal environments. This material appears to have come from inside Ceres, because an impacting asteroid could not have delivered it. The upwelling of this material suggests that temperatures inside Ceres are warmer than previously believed. Impact of an asteroid on Ceres may have helped bring this material up from below, but researchers think an internal process played a role as well.
More intriguingly, the results suggest that liquid water may have existed beneath the surface of Ceres in recent geological time. The salts could be remnants of an ocean, or localized bodies of water, that reached the surface and then froze millions of years ago.
Blue Cross Blue Shield is losing money nationwide because of Obamacare
Finding out what’s in it: Because of Obamacare, Blue Cross Blue Shield is losing money in states across the nation, forcing them to request rate increases of more than 50 to 65 percent.
If the federal government does approve these rate increases, expect most oif their customer base to vanish. If they don’t get these rate increases, expect them to abandon the market in those states.
So much for Obama’s promise that Obamacare would bend the cost curve downward, cutting rates by $2500 per family. Too bad no one told him his numbers were completely bogus and that Obamacare would increase everyone’s cost, and possibly destroy the health insurance industry. Oh wait… that was what those evil tea partiers and conservatives were saying.
