It appears that last week”s news of the death of China’s first lunar rover, Yutu, were premature. The rover is actually only in hibernation, and might come back to life next month, with limited capabilities.
The competition heats up: SpaceX this morning successfully put another satellite in orbit while also recovering another Falcon 9 first stage.

The constitution is such an inconvenient thing: A new Obama executive order has redefined the work of gunsmiths to define them as manufacturers so that they can be much more heavily regulated, and likely put out of business.
The president’s executive order, which Obama signed on July 22 — around the beginning of the Democratic National Convention — conveys to the State Department’s Directorate of Defense Trade Controls (DDTC), which is primarily in charge of managing the Arms Export Control Act (AECA) and establishing its rules, the International Traffic in Arms Regulations (ITAR).
DDTC now names commercial gunsmiths as “manufacturers” for relatively simple tasks as threading a barrel or duplicating a small custom part for an older firearm.
The law would require gunsmiths to spend thousands to meet the regulations, and would likely put most out of business, or force them underground into a black market.
The worst part of this, beyond the fact that it is a naked attack on law-abiding citizens because they do work Obama and liberals hate, is that if this executive order stands, it will grant the federal government unlimited power to destroy almost anyone in blue collar work that they don’t like Repair a car, install a carpet, fix a home’s air conditioning system, replace some plumbing, and you suddenly can be declared a manufacturer that no longer can afford to be in business.

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
Two years after the last previous case and only one year from declaring Nigeria polio-free, two children have been diagnosed with the crippling virus.
They are going to immediately begin immunizing 5 million children in the affected region.
Coincidentally, that area has been the epicenter of an insurgency waged by Boko Haram, an Islamist militant group that has killed tens of thousands of people and displaced more than 2 million since their fight began in 2009. During Boko Haram’s time in Borno, the group has been responsible for destroying hundreds of health centers, and has caused so much damage in some areas that it has become hard for vaccinators to do their jobs effectively.
One can’t help wondering if these new cases occurred because of this Islamic insurgency.
Posted on the road from Tucson to the Grand Canyon.
Diane and I are about to leave for our annual trip to the bottom of the Grand Canyon. This trip will be short, down on Saturday and up on Sunday. As usual, the trip will be grand (pun intended). I should be able to post tonight and on Sunday and Monday, but I will be traveling and will have other priorities (like enjoying myself). Even so, I might post something on our trip, especially considering that this will be second trip in a row to Phantom Ranch where the water system is broken and, though there is drinking water, there will be no showers. More details to follow.
There are now only 3 copies left of the now out-of-print hardback of Leaving Earth. The price for an autographed copy of this rare collector's item is now $150 (plus $5 shipping).

In a radio interview today Donald Trump said that he was seriously considering appointing John Bolton as his secretary of state.
This could simply be pandering by Trump to the conservative audience he was speaking to, or it could be a real trail balloon. Either way, it emphasizes again that the policies of a president is largely determined by the people he surrounds himself with, first by indicating the direction the president is leaning, and second by providing counsel to that president. So far, the majority of Trump’s picks have leaned to the right, with some exceptions. Bolton would emphasize that rightward direction, and this is a very good thing.
By the way, I don’t know if my readers have noticed this, but the stories I have posted here about the presidential election campaign have had nothing to do with the stupid stuff that the mainstream and conservative media have been obsessing about. Instead, my focus, as always, is on trying to find out what these candidates will actually do when they become president, based on what they actually do (not say). Thus, I post about Trump’s potential appointments once in office, and real evidence that Hillary Clinton committed illegal acts as secretary of state. Making believe that Donald Trump is a monster because he made a minor miscue at one point in one speech is not a way to learn anything, other than to demonize the man absurdly and wrongly. I won’t participate in that childishness.
Many cool images! The Rosetta team has released a bunch of very nice images taken of Comet 67P/C-G during August when the spacecraft was flying in close. The image on the right, cropped and reduced in resolution to post here, shows the comet’s large lobe, with the narrow neck to the left. Make sure you check out the full resolution image. It was taken on August 10, 2016 from about 8 miles away, and has a resolution of less than four feet per pixel. If a person was standing there you could just see them!
What I find most fascinating is the incredible curvature of the comet’s surface. The smooth area on the left, dubbed Imhotep (images of which have been posted here previously), has several big boulders on its flat surface. If you stood there, the ground would be down and horizontal. Walk only a short distance and you quickly reach the curving horizon and that flat area would look like a steep slope dropping down behind you. Yet, the boulders do not roll down hill! Walk a short distance more and you begin to enter the neck region, with giant walls rising above you, until you start to walk up them and they become the floor!
The Russian space station replacement for ISS, dubbed the Russian Orbital Station (ROS), faces serious budget problems that might delay its launch.
Plans for the post-ISS Russian Orbital Station, ROS, are in limbo, as the nation’s space program has faced budget cuts in 2016. Although the industry has now completed formulating the overall design of the future station, the cash-strapped Roskosmos was yet to approve the formal technical assignment for the development of ROS as of June 2016. The addendum to the Federal Contract, which would fund further development work on the project, has not been issued either.
The ROS project stalled despite being formally approved by three strategy documents governing the current Russian space program: The 10-year Federal Space Program from 2016 to 2025, known as FKP-2025; The Strategy for Russian Piloted Space Flight until 2035 and the Concept of the Russian Piloted Space Flight.
The article also provides a nice overview of how Russia hopes to assembly ROS, partly from new modules and partly from modules they will detach from ISS. The article also made this key point:
According to the current ROS concept, the new Russian station will have a truly unlimited life span, thanks to the possibility to replace any of its modules. (It is practically impossible with the current ISS architecture.) The new Russian station is also designed to operate either as a permanently inhabited outpost or as a periodically visited facility. Russian strategists also hope that the new station will inherit the international nature of the ISS project.
I think Russia is beginning to see the operation of Earth orbital space stations as a profitable niche they can occupy. They know how to do it and already have the technology on hand, and can do it at very affordable prices. Whether they can afford it themselves, however, remains an open question.
An Indian astronomer, in testimony to India’s parliament, has explained that for engineering and technical reasons India will likely not be the new location of the Thirty Meter Telescope (TMT).
Essentially, the skies are clearer in the Canary Islands and in Chile.
This story is important in that it confirms that the consortium building TMT is now very seriously considering abandoning Hawaii, and might already have decided to do so. It also suggests that the Canary Islands is in the lead as the new location, since they want a site that can see the skies of the northern hemisphere, something that won’t be possible in Chile.
The competition heats up: Aerojet Rocketdyne has signed a contract with NASA to develop a small thruster engine for use on cubesats.
The MPS-130 green propulsion system will allow CubeSats and SmallSats to increase their capabilities, such as extending mission life, increasing architecture resiliency, maneuvering to higher and lower orbits, and performing complex proximity operations and formation flying. The use of additive manufacturing also reduces the number of parts and amount of time required to fabricate and assemble the modular propulsion system, lowering the cost of small satellites for private and public operators. Under the contract, Aerojet Rocketdyne will deliver a fully-integrated MPS-130 green modular propulsion system for flight demonstration, as well as conduct development and validation testing.
The press release does not say how much money NASA is providing. Regardless, this is a great opportunity for Aerojet Rocketdyne, because the smallsat industry is I think about to take off, and at the moment these tiny satellites lack any useful technology for maneuvering. Up until now they were mostly designed as temporary short term satellites built mostly to teach students. Soon, however, there will be a lot of privately-built commercial smallsats launched, designed to make money. Being able to sell their builders a thruster that could prolong their life and make them more capable will give Aerojet Rocketdyne a product that will certainly sell like hotcakes.
This ESA press release provides a nice overview of the landing area that the Schiaparelli lander on ExoMars is targeting.
The landing ellipse, measuring 100 x 15 km, is located close to the equator, in the southern highlands of Mars. The region was chosen based on its relatively flat and smooth characteristics, as indicated in the topography map, in order to satisfy landing safety requirements for Schiaparelli. NASA’s Opportunity rover also landed within this ellipse near Endurance crater in Meridiani Planum, in 2004, and has been exploring the 22 km-wide Endeavour crater for the last five years. Endeavour lies just outside the south-eastern extent of Schiaparelli’s landing ellipse.
Since the primary missions of both Schiaparelli and the ExoMars orbiter, dubbed the Trace Gas Orbiter, is test the technology for getting to and landing on Mars (in preparation for the more challenging 2020 ExoMars mission), I suspect that they chose this very well studied and already visited area to make this test landing less risky.
Side note: ExoMars successfully completed its second and last planned mid-course correction yesterday in preparation for its October arrival at Mars.

After several days of drilling, the Curiosity science team is preparing to move forward. As one member of the team notes,
After a short drive we’ll acquire images for context and targeting. Overnight, Curiosity will complete a SAM electrical baseline test to monitor instrument health. Based on some of the recent Mastcam images that we’ve acquired…, the view ahead should be quite scenic as we drive through the Murray Buttes!
The image above is a close-up of those Buttes, showing Balanced Rock on the left, taken from one of three raw left navigation images. The image below is a panorama I have created from those navigation images, with an inset box to show the location of the above picture.

In the heat of competition: Russia is considering reducing its ISS crew from three to two.
“Plans to reduce the crew stem from the fact that less cargo ships are sent to the ISS and from the necessity to boost the efficiency of the program,” the newspaper quotes Krikalev. Apart from that, it will make it possible to lower expenses on the space station’s maintenance.
They haven’t yet made a decision. I suspect that the real reason they are considering this idea is because it will free up a seat on the Soyuz spacecraft that they can then sell to tourists, something they have been unable to do since the station got large enough for the full crew of six and the U.S. became dependent on them for crew ferrying.. By only sending two Russians astronauts up with each Soyuz launch they will then have a free seat for short tourist flights, which had been quite lucrative for them.
An evening pause: I especially like the sound clarity and sharpness of the electric guitar playing.

Cool image time! The image above, cropped and reduced in resolution to show here, was taken on May 30, 2016 by Dawn from 240 miles away. It looks northward at the dwarf planet’s horizon, and has a resolution of about 120 feet per pixel.
My only comment is to note how soft the terrain looks. I realize this is not really an accurate description, but data has shown that Ceres has a somewhat low density and is somewhat malleable. It sure looks that way here.
New emails reveal that Democratic candidate Hillary Clinton used her position as Secretary of State to pass out favors in exchange for donations to her foundation.
The facts are very welled documented here. Hillary Clinton wasn’t interested in acting as Secretary of State. She was interested in garnering cash donations for herself and Bill Clinton, and used her position of power to hand out favors for those donations.
But don’t worry! Our valiant press is on the ball, screaming about petty miscues by Donald Trump that mean nothing, are taken badly out of context, and are largely irrelevant to the kind of President he might be. That the Democrat running against him is a proven liar, law-breaker, and incredibly corrupt is just not important to them. All that matters is that she is a Democrat, and part of their team!
Which by the way should give us all a bit of a pause to consider how dishonest, illegal, and corrupt the entire elite culture of the U.S. has likely become. As I said, Clinton is part of their team.
In the heat of competition: Orbital ATK has once again pushed back the launch of the first upgraded Antares rocket since its launch failure in October 2014, this time until September.
Due to a variety of interrelated factors, including the company’s continuing processing, inspection and testing of the flight vehicle at Wallops Island, and NASA’s scheduling of crew activities on the International Space Station in preparation for upcoming cargo and crew launches, Orbital ATK is currently working with NASA to target a window in the second half of September for the launch of the OA-5 mission. A more specific launch date will be identified in the coming weeks.
This press release suggests that all is well, and that the delay is mostly because of scheduling issues with NASA and ISS. However, it is also very vague, which suggests to me that the company has been also working through the results of the static fire test they did in May and might have needed more time to work out the kinks..
The competition heats up: SpaceX’s first Raptor rocket engine has now been built and has been shipped to the company’s test facility in Texas to begin testing.
The Raptor is SpaceX’s next generation of rocket engine. It may be as much as three times more powerful than the Merlin engines that power its Falcon 9 rocket and will also be used in the Falcon Heavy rocket that may fly in late 2016 or early 2017. The Raptor will power SpaceX’s next generation of rocket after the Falcon Heavy, the so-called Mars Colonial Transporter.
Although official details regarding the Raptor engine remain scarce, SpaceX founder Elon Musk has suggested the engine will have a thrust of about 500,000 pounds, roughly the same power as a space shuttle’s main engines. Whereas the shuttle was powered by three main engines and two booster rockets, however, it is believed the large rocket SpaceX uses to colonize Mars would likely be powered by a cluster of nine Raptor engines.
Like I said in my previous post, the rest of this decade should be very exciting in space, and that excitement will have be because of private enterprise and freedom, not NASA’s fake mission to Mars, with Orion.
The competition heats up: A private company, Deep Space Industries (DSI), has announced plans to send the first privately-built probe to an asteroid before the end of the decade.
Recently, Deep Space Industries and its partner, the government of Luxembourg, announced plans to build and fly Prospector-X™, an experimental mission to low-Earth orbit that will test key technologies needed for low-cost exploration spacecraft. This precursor mission is scheduled to launch in 2017. Then, before the end of this decade, Prospector-1 will travel beyond Earth’s orbit to begin the first space mining exploration mission.
Note that this funding is another example of the Luxembourg government’s effort to invest in commercial space, for profit.
If all goes as planned, the rest of this decade should be very exciting. We will have a private mission to the Moon, a private mission to an asteroid, and a private mission to Mars. All will cost pennies compared to what the government spends. All will be built and launched quickly, compared to how long the government takes. And all will be for profit, which is certainly not what the government is interested in.
Cool image time! New data from Cassini has now both confirmed that there is liquid inside some of the river-like formations on Titan, and that this liquid has carved these formations into very deep gorges.
The Cassini observations reveal that the channels — in particular, a network of them named Vid Flumina — are narrow canyons, generally less than half a mile (a bit less than a kilometer) wide, with slopes steeper than 40 degrees. The canyons also are quite deep — those measured are 790 to 1,870 feet (240 to 570 meters) from top to bottom.
The branching channels appear dark in radar images, much like Titan’s methane-rich seas. This suggested to scientists that the channels might also be filled with liquid, but a direct detection had not been made until now. Previously it wasn’t clear if the dark material was liquid or merely saturated sediment — which at Titan’s frigid temperatures would be made of ice, not rock.
The diagram on the above right is from the paper itself, and shows some of the radar data obtained by Cassini. It also illustrates the deep and narrow nature of Via Flumina. This is almost the equivalent of what we call slot canyons on Earth, formed by periodic flash floods that cut their way down as the surface is slowly uplifted by other processes.
The new radar data showed that the surface at the base of the gorge was smooth and flat, just as you’d find if that base was filled with liquid.The altimeter data showed that gorge’s elevation matched that of Titan’s lakes at its insurgence, but as you traveled upstream the elevation rose, just as it does on any river on Earth. Moreover, this data was reasonably trustworthy as they had already used Cassini to successfully do exactly the same thing — identify a known river — when it flew past Earth on its way to Saturn.
Be prepared for one piece of misinformation when the press reports on this story, almost certainly caused by the American Geological Union’s press release about this paper. That press release incorrectly claims that the paper confirmed that these are methane rivers. It does no such thing. It only shows that the gorges have a liquid in them, and that the liquid almost certainly formed the gorges. Though methane is a very likely candidate for this liquid based on what we know of Titan, the actual make-up of the river remains uncertain.
I therefore predict our incompetent modern mainstream press will only read this press release and not the paper itself, and thus they will tout these incorrectly as methane rivers.
Below is a cropped Cassini radar image of Via Flumina, showing its river-like appearance. Scientists always suspected these were formed by flowing liquid. Now they have strong evidence from within the gorge to justify that suspicion.
An evening pause: This video release from NASA made the rounds a few weeks ago. It isn’t news, but it is cool. One important fact noted during this video is that the Earth’s cloud cover both warms and cools the planet. What wasn’t noted was that there is gigantic uncertainty about how much the clouds warm and cool, which is one of the main reasons no climate models have been even close to successfully predicting the climate.

The court suit story is here, while the endorsement of Clinton by the father of the Orlando terrorist is here.
Makes sense to me. Based on her track record I would expect Clinton to be endorsed by a man with ties to the Taliban and who posts anti-American videos on the web.
Academic bigots: An Illinois college is proud to offer “blacks-only” courses.
“[College 101] provides an opportunity to assess your purpose for college, assess your study strategies, set college and career goals, examine your values and decision-making skills, and develop an appreciation for diversity,” the course catalog states. [emphasis mine]
Next thing I expect academia to suggest is that blacks really shouldn’t have to use the same water fountains, buses, or schools as whites, and should be given separate but equal facilities. Otherwise, how else can they learn to appreciate diversity!
Cool image time! The image on the right, cropped to show here, was taken by Mars Odyssey. While the features shown appear at first glance to have been formed by water, they have instead in etched by wind.
The narrow ridge/valley system seen in this image are a feature called yardangs. Yardangs form when unidirectional winds blow across poorly cemented materials. Multiple yardang directions can indicate changes in regional wind regimes.
The release does not say what direction the wind was blowing, but if I had to guess, I’d say from south to north.
The uncertainty of science: A year’s collection of data using IceCube, a gigantic neutrino telescope built in the icecap of Antarctica, has found no evidence of a theorized fourth type of neutrino.
To search for sterile neutrinos, Halzen’s team looked for the arrival of muon neutrinos that started life on the other side of Earth. These were originally produced by the collision of cosmic rays with air molecules in the atmosphere, and passed through the planet to reach the detector. The IceCube team hoped to find a dearth of muon neutrinos at particular energies. That would have suggested that some muon neutrinos had temporarily mutated into sterile neutrinos during their voyage.
But, after analysing the results of a year’s worth of data, the researchers found no feature suggesting the existence of sterile neutrinos around 1 eV. This is line with results from the European Space Agency’s Planck observatory, which concluded from cosmological evidence that there should only be three families of neutrinos in that mass range. “I hope that with our result and with the Planck result we are slowly walking our way back from this story,” says Halzen. The IceCube team are still taking data in their sterile neutrino hunt, but don’t expect their results to change, he adds.
Despite this null result, there is still a possibility that sterile neutrinos exist, but not at the mass predicted.
The competition heats up: Doug Messier has posted a nice summary of the most important presentations so far at Smallsat 2016 in Utah.
These are the rockets designed to launch cubesats or smaller. It appears that at least two companies, Firefly and Vector Space Systems, are getting close to their first flights. Both already have customers. The progress of a third company, Virgin Galactic, sounds as good, but they have talked big too many times in the past to trust them at this point. In fact, regardless of what any of these companies say, it will be actual flights that puts them on the map.
What is interesting is the number of these companies. There are a lot of them, which suggests strongly that some are going to succeed.
In taking his family on a tour of the Johnson Space Center, Senator Ted Cruz (R-Texas) also met with some local industry businessmen where he expressed support for NASA as well as a desire to get ISS extended to 2028.
Cruz did not take questions from the media, though they were present during the meeting with businessmen. In reviewing the local press reports of that meeting (of which the above link is the most detailed), it appears that Cruz was mostly there to firm up his local constituent support by mouthing vague but strong support for NASA. It also appears that he as yet does not have a clear understanding of NASA’s full circumstances, or if he does he is leaning down the pork road to gain votes.
When my policy paper appears I intend to make sure his office gets it. By his actions after that we shall then see how sincere Ted Cruz really is about fiscal responsibility and private enterprise.
