After six months and a short pause in work while engineers analyzed a short circuit, Curiosity has finally left the Pahrump Hills are on the slopes of Mount Sharp.
The rover has begun driving away from the Pahrump Hills outcrop where it had spent the last six months. On Thursday, March 12, it drove about 33 feet (about 10 meters) southwestward. The rover team plans on taking Curiosity through a valley called “Artist’s Drive” to reach higher geological layers of Mount Sharp. Curiosity is currently heading towards a rock outcrop known as “Garden City.”

Theft by government: The Arkansas SWAT team kidnapping of seven children from their parents continues, with the hearing that was supposed to settle the issue and get the children home postponed for six weeks for no reason.
It will be at least “6 more weeks of kidnapping” for the 7 homeschooled, homebirthed Stanley children, according to their father. Hal and Michelle Stanley were given no warning that their court hearing scheduled for February 12 would be abruptly postponed until March 23. They say they were not given any explanation as to why the hearing was postponed.
They had been under the impression that their children would be coming home after the hearing, and had held onto the hope that the crazy situation would be resolved, and their family would be reunited. The pain in their voices was palpable as they expressed their disappointment and grief over the postponement.
The father explains to Health Impact News that they are only allowed to visit with their children a few hours a week, under strict supervision. There has to be two observers, and if they talk about things they are not supposed to discuss with their children, the visit is cut short. As a condition to these supervised visits, Hal and Michelle must attend “parenting classes,” even though they have homeschooled their children for many years. Hal Stanley is also a 73 year old ordained Southern Baptist Minister.
As said back in January when I first reported this horrifying story, read it all, it will terrify you. The parents have been charged with no crime and there is no evidence at all of them abusing their children. The whole issue was supposedly prompted because the Stanleys used a legal water purifier for their garden that the has not been approved by the FDA.
Yet, the state now claims the power to steal this family’s children, with no legal justification.

An evening pause: Good music, but this video reveals a great deal about the future in how it portrays an adolescent view of the present. Even more important, the view is very typical of modern culture.
The rage builds: “So I’d like to ask the Fed, is it that you just hate the working class here in America and thus like to torment them or are you truly that stuck up your own asses that you just cannot see the light?”
Read it all. I don’t agree with his perspective entirely, but I do agree that the elite of this country are increasingly ignoring the wishes of the general public, for their own gain and to the detriment of everyone else. If they don’t stop this behavior soon, they are going to find this rage coming back to bite them, and that bite is going to hurt everyone very badly.

And the best images are yet to come, this July, when New Horizons makes its fly-by.
The competition heats up: Russia has decided to abandon an expensive attempt to build an SLS-like super-rocket and will instead focus on incremental development of its smaller but less costly Angara rocket.
Facing significant budgetary pressures, the Russian space agency, Roscosmos, has indefinitely postponed its ambitious effort to develop a super-heavy rocket to rival NASA’s next-generation Space Launch System, SLS. Instead, Russia will focus on radical upgrades of its brand-new but smaller Angara-5 rocket which had its inaugural flight in Dec. 2014, the agency’s Scientific and Technical Council, NTS, decided on Thursday, Mar. 12.
For Russia’s space industry, it appears that these budgetary pressures have been a blessing in disguise. Rather than waste billions on an inefficient rocket for which there is no commercial demand — as NASA is doing with SLS (under orders from a wasteful Congress) — they will instead work on further upgrades of Angara, much like SpaceX has done with its Falcon family of rockets. This will cost far less, is very efficient, and provides them a better chance to compete for commercial launches that can help pay for it all. And best of all, it offers them the least costly path to future interplanetary missions, which means they might actually be able to make those missions happen. To quote the article again:
By switching upper stages of the existing Angara from kerosene to the more potent hydrogen fuel, engineers might be able to boost the rocket’s payload from current 25 tons to 35 tons for missions to the low Earth orbit. According to Roscosmos, Angara-A5V could be used for piloted missions to the vicinity of the Moon and to its surface.
In a sense, the race is now on between Angara-A5V and Falcon Heavy. It shall be quite exciting to watch this competition unfold between big government and private enterprise over the next few decades.
An Atlas 5 rocket successfully launched four NASA research satellites Thursday night designed to study the behavior of the Earth and Sun’s magnetic fields at high resolution.
The quartet of observatories is being placed into an oblong orbit stretching tens of thousands of miles into the magnetosphere — nearly halfway to the moon at one point. They will fly in pyramid formation, between 6 miles and 250 miles apart, to provide 3-D views of magnetic reconnection on the smallest of scales.
Magnetic reconnection is what happens when magnetic fields like those around Earth and the sun come together, break apart, then come together again, releasing vast energy. This repeated process drives the aurora, as well as solar storms that can disrupt communications and power on Earth. Data from this two-year mission should help scientists better understand so-called space weather.
Rosetta’s high resolution camera has taken a color image of Comet 67P/C-G’s narrow neck, the area where the most plume activity has taken place.
When seen with the human eye, comet 67P/Churyumov-Gerasimenko is grey – all over. With its color filters Rosetta’s scientific imaging system OSIRIS, however, can discern tiny differences in reflectivity. To this effect, scientists from the OSIRIS team image the same region on the comet’s surface using different color filters. If, for example, the region appears especially bright in one of these images, it reflects light of this wavelength especially well.
“Even though the color variations on 67P’s surface are minute, they can give us important clues”, says OSIRIS Principal Investigator Holger Sierks from the Max Planck Institute for Solar System Research (MPS) in Germany. In a recent analysis performed by the OSIRIS team, the Hapi region clearly stands out from the rest of the comet: while most parts of 67P display a slightly reddish reflectivity spectrum as is common for cometary nuclei and other primitive bodies, the reflection of red light is somewhat lower in this region.
They as yet do not know exactly why the smooth area at the neck has a very slight blueish tinge, though they suspect it is because of the presence of a higher percentage of frozen water.
The uncertainty of science: The Chinese lunar rover Yutu has uncovered a much more complicated geology history than previously predicted at its landing site on the moon.
Those data paint a detailed portrait of the Chang’e 3 landing site, which sits just 165 feet (50 m) away from a 1,475-foot-wide (450 m) crater known as C1. C1 was gouged out by a cosmic impact that occurred sometime between 80 million and 27 million years ago, the study authors said.
Yutu studied the ground it rolled over, characterized the craters it cruised past and investigated an oddly coarse-textured rock dubbed Loong, which measures about 13 feet long by 5 feet high (4 by 1.5 m). Overall, the rover’s observations suggest that the composition of its landing site is quite different from that of the places visited by NASA’s Apollo missions and the Soviet Union’s Luna program.
The rover found 9 distinct layers, suggesting numerous and different past events that layered the surface.
The competition heats up: Bigelow Aerospace today unveiled the inflatable habitable module it is building for ISS that will launch in September.
The total cost for this module was $17 million, compared to the billion that NASA routinely spent to build its own modules.
