Our government in action! An American citizen has sued and won almost a half a million dollars from the federal government for subjecting her to a random strip search upon her return to the states from Mexico.
Read the article. Customs agents essentially raped her. Worse, the agents won’t pay the bill, it will be you, the taxpayer.
As I predicted Sunday, the Curiosity science team is aiming the rover directly towards the gap in the mesas, dubbed the Murray Buttes, that also has the balanced rock seen in earlier images.
The image on the right shows the rover’s most recent two traverses, superimposed on a Mars Reconnaissance Orbiter image. I have cropped it to focus in on the area of most interest.
Based on the rover’s general rate of travel, I would expect them to enter the gap after about two or three more traverses. This means they will be there in about a week, since after each traverse they usually stop and do science and reconnaissance before resuming travel.
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.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
"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
ExoMars 2016, the European/Russia orbiter/lander mission on its way to Mars, successfully completed a 52 minute mid-course engine burn today in preparation for its October 19th arrival at Mars.
Officially known as the deep-space maneuver, DSM, it was the longest engine burn for the ExoMars-2016 mission before the Mars orbit insertion on October 19, 2016. As a result of the July 28 orbit correction, the spacecraft will need less propellant during its maneuvers in the vicinity of the planet and the Schiaparelli lander will experience slightly less thermal loads during its planned entry into the Martian atmosphere.
Using the data from Rosetta, scientists have developed a detailed scenario for the birth process that created Comet 67P/C-G.
During its two-year sojourn at Comet 67P/Churyumov–Gerasimenko, Rosetta has revealed a picture of the comet as a low-density, high-porosity, double-lobed body with extensive layering, suggesting that the lobes accumulated material over time before they merged.
The unusually high porosity of the interior of the nucleus provides the first indication that this growth cannot have been via violent collisions, as these would have compacted the fragile material. Structures and features on different size scales observed by Rosetta’s cameras provide further information on how this growth may have taken place.
Earlier work showed that the head and body were originally separate objects, but the collision that merged them must have been at low speed in order not to destroy both of them. The fact that both parts have similar layering also tells us that they must have undergone similar evolutionary histories and that survival rates against catastrophic collision must have been high for a significant period of time.
In other words, the comet’s two lobes formed slowly as separate bodies but always in the same general region, and then moved closer and closer together until they gently merged. Based on this scenario, Comet 67P/C-G had to have formed very early in the solar system, and also was not in the inner solar system — as it is now — when the great early bombardment occurred there about a billion years ago.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

The competition heats up: A ULA Atlas 5 rocket today successfully launched a National Reconnaissance Office (NRO) surveillance satellite, dubbed NROL-61.
The image on the right is courtesy of Orbital ATK. From the link above:
NROL-61, however, launched atop an Atlas V 421 rocket, a configuration that has not previously been used by the NRO. The spacecraft itself was encapsulated within an Extra-Extended Payload Fairing (XEPF) – at 14 metres (46 feet) in length the longest of three available four-metre (13-foot) diameter fairings – which has also never before been used for an NRO mission.
…The most likely explanation is that NROL-61 will be the first in a new generation of Quasar satellite; which would appear to be larger in both size and mass than its predecessors. Quasar, also known as the Satellite Data System, or SDS, is a constellation of communications satellites operated by the NRO to support its other intelligence-gathering activities; relaying data from other satellites to the ground in real-time, without having to wait for the intelligence-gathering satellites to pass over ground stations on friendly territory. If NROL-61 represents a new version of Quasar, it will be the fourth generation of the constellation.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
The Government Accountability Office today issued two reports, both of which said that the SLS and Orion programs are faced with more cost overruns and schedule delays.
The GAO found that cost overruns for Orion could be as high as $707 million and that work is “not being accomplished as scheduled.” It also found challenges with the capsule’s software and heat shield, and said that the space capsule’s cost and schedule “estimates are not reliable.”
Other than that, everything is peachy keen! These reports, (the Orion report is found here [pdf] and the SLS report here [pdf], especially the Orion one, also suggest that the first manned Orion mission, now scheduled for 2021, stands a good chance of being delayed again, possibly for two more years.
This just confirms what I have written in my soon-to-be published policy paper, Exploring Space in the 21st Century. In fact, I need to add these GAO reports to my sources!
At a meeting of NASA’s Advisory Council yesterday a NASA official estimated that SpaceX will probably spend about $300 million on its Dragon mission to Mars.
Asked by the committee how much SpaceX was spending, Reuter indicated that the company’s investment was 10 times that of NASA. “They did talk to us about a 10-to-1 arrangement in terms of cost: theirs 10, ours 1,” he said. “I think that’s in the ballpark.” Given NASA’s investment, that implies SpaceX is spending around $300 million on Red Dragon.
SpaceX has not disclosed its estimated cost of the mission, or how it will pay for it. “I have no knowledge” of how the company is financing the mission, Reuter said when asked by the committee.
I suspect that the guess is significantly wrong. NASA is providing $32 million. SpaceX plans to charge customers $90 million for a single Falcon Heavy launch, which means its cost for that launch is likely half that, say $45 million. That adds up to $77 million. The cost for a Dragon capsule is not even close to $223 million, which is what remains if NASA’s guess is right, which based on this rough estimate I seriously doubt. I would bet that a single Dragon probably costs far less than $20 million. Remember, they are nothing more than basic manned capsules, and SpaceX is building enough of them to almost have an assembly line going.
So, let’s round up and say that the cost for the mission is really about $100 million (including NASA’s contribution). Other costs, such as the staff to run the mission for at least a year, will increase this cost, but not enough to bring the total to NASA’s guess of $300 million. I suspect that SpaceX will not spend anything close to $100 million of its own money for this Dragon mission to Mars.
All in all, this amount of investment seems reasonable, based on the scale of costs in the launch industry. And SpaceX’s willingness to invest some of its own money for this mission is probably wise. In publicity alone it is priceless.
Jupiter’s Great Red Spot, a giant storm that has been raging for at least three centuries, turns out to be the hottest spot on Jupiter.
They suspect that the spot is heated from below, but really understand much else, or even that.
Juno is specifically designed to study the weather patterns of Jupiter, so we will get some of these answers, plus a lot more questions, in the coming years as the spacecraft gathers its data.
An evening pause: Waterholes Canyon is a side canyon leading down into the Colorado River, north of the Grand Canyon. The people canyoneering here are caving friends of mine. The video was created by Kimberly Franke, whom you pretty much only see in the opening still shot, since she was wearing the camera most of the time. Her husband Kevin Franke is also a fellow caver who is the person with the white helmet and thick whitish beard. The woman in the red helmet doing the very long drop near the end is Belinda Norby, also a fellow caver. The music is “Point of No Return” by Roger Subirana Mata.
The world is filled with amazing things to see. This video does a nice job of highlighting just one of them.
Several weeks ago NASA put out one of its periodic press releases touting the wonders of the engineering the agency is doing to prepare for its future missions to Mars. In this case the press release described a new exercise device, dubbed ROCKY (for Resistive Overload Combined with Kinetic Yo-Yo), for use in the Orion capsule.
“ROCKY is an ultra-compact, lightweight exercise device that meets the exercise and medical requirements that we have for Orion missions,” said Gail Perusek, deputy project manager for NASA’s Human Research Program’s Exploration Exercise Equipment project. “The International Space Station’s exercise devices are effective but are too big for Orion, so we had to find a way to make exercising in Orion feasible.
As is their habit these days in their effort to drum up support for funding for SLS and Orion, the press release was filled with phrases and statements that implied or claimed that Orion was going to be the spacecraft that Americans will use to explore the solar system.
…engineers across NASA and industry are working to build the Orion spacecraft and Space Launch System rocket that will venture to deep space for the first time together…
…Over the next several years, NASA’s Human Research Program will be refining the device to optimize it not only for near-term Orion missions with crew, but for potential uses on future long-duration missions in Orion…
These are only two examples. I have clipped them because both were very carefully phrased to allow NASA deniablity should anyone question these claims. For example, in the first quote they qualify “deep space” as specifically the 2018 unmanned lunar test flight. And the second quote is qualified as referring to missions to lunar space. Nonetheless, the implied intent of this wording is to sell Orion as America’s interplanetary spaceship, destined to take us to the stars!
Don’t believe me? Then take a look at NASA’s own Orion webpages, starting with the very first words on their Orion Overivew page.

This link takes you to a post on The Landslide Blog, showing videos of three landslides in China. The first is especially fascinating to watch.
The video I have posted below the fold, posted at this link, was taken outside the convention after Bernie Sanders endorsed Hillary Clinton.
[O]nce Bernie Sanders endorsed Secretary Clinton via a rules change request throwing all delegate votes to Hillary, the vast majority of movement democrats left the arena. Immediately following the roll call vote, the DNC quickly moved to bar any pro-Sanders signage from the venue. Anyone holding Sanders signs was warned they were subject to forced removal and loss of convention credentials. Outside the arena the Bernie Sanders supporters gathered to voice their protest to the strong arm tactics. [emphasis in original]
The video shows a pro-Clinton (and former Sanders) delegate talking to the press about how wrong the Sanders protesters are. As he talks he is challenged by one of those protesters, who loudly disagrees with him.
What the video shows clearly is that the mainstream press is only interested in recording and interviewing the pro-Clinton guy. In fact, when the guy taking this video begins to note loudly this obvious bias to everyone (beginning at around 1:50), the press suddenly realizes how biased they look and some make a half-hearted effort to make believe they are interested in talking to the Sanders protester.
What I find most significant about this video, and quite entertaining, is how it demonstrates how completely useless today’s mainstream press is, and how that press is increasingly losing all influence because the general public has access to many other lone guys with a camera, videotaping events and showing us what is really happening.
In other words, don’t depend on just television news for your information. You will not only be uninformed, you will be misinformed.
The uncertainty of science: Astrobiologists are meeting this week in Seattle to discuss and refine their methods for detecting astrobiology on exoplanets.
The Seattle meeting aims to compile a working list of biosignature gases and their chemical properties. The information will feed into how astronomers analyse data from NASA’s James Webb Space Telescope, slated for launch in 2018. The telescope will be able to look at only a handful of habitable planets, but it will provide the first detailed glimpse of what gases surround which world, says Nikole Lewis, an astronomer at the Space Telescope Science Institute in Baltimore, Maryland.
No single gas is likely to be a slam-dunk indicator of alien life. But Domagal-Goldman hopes that the workshop will produce a framework for understanding where scientists could trip themselves up. “We don’t want to have a great press release,” he says, “and then a week later have egg on everybody’s faces.”
A few years ago I was told by one astronomer that the field’s biggest and most exciting area of research in the coming decades will be the effort to study the thousands exoplanets they only just discovered. I agree. The Webb telescope might have been built to study cosmology, but the data it will produce about exoplanets will be much more real and less uncertain, thus making it more compelling and convincing.
China has built the world’s largest amphibious plane, designed initially for rescue and fire-fighting duties.
Made by the state’s aircraft maker, the AG600 is around the size of a Boeing 737 and will be used to douse forest fires and rescue people in danger offshore. Measuring 37 m (121 ft) long with a wingspan of 38.8 m (127 ft), the gargantuan amphibious aircraft is capable of taking off and landing both on terra firma and stretches of water, provided they are more than 1,500 m long, 200 m wide and 2.5 m deep (0.93 mi, 656 ft and 8.2 ft). It has a maximum take-off weight of 53.5 tonnes (59 tons), a top cruising speed of 500 km/h (310.7 mph) and a range of 4,500 km (2,800 mi), and can fly for 12 hours at a time, according to its builder, the Aviation Industry Corporation of China (AVIC).
Much like the Russians, the Chinese aerospace industry is controlled and supervised by the government. Unlike the Russians, however, the Chinese for the moment seem much more capable under this top-down system to develop new designs. They say for example that this new amphibious plane already has 17 domestic orders.
I must admit to a bit of skepticism however. Was this plane built because there was a demand, or because the powers-that-be decided they wanted it built? I am not sure. The video at the link suggests to me the latter, with its hard core sales pitch similar to a lot of other government projects I have seen, where the project is built because some politician or bureaucrat conceived and pushed it, but it doesn’t really have a viable purpose.
The uncertainty of science: Astronomers have now detected and measured a new class of large but very dim galaxy that previously was not expected to exist.
‘Ultradiffuse’ galaxies came to attention only last year, after Pieter van Dokkum of Yale University in New Haven, Connecticut, and Roberto Abraham of the University of Toronto in Canada built an array of sensitive telephoto lenses named Dragonfly. The astronomers and their colleagues observed the Coma galaxy cluster 101 megaparsecs (330 million light years) away and detected 47 faint smudges.
“They can’t be real,” van Dokkum recalls thinking when he first saw the galaxies on his laptop computer. But their distribution in space matched that of the cluster’s other galaxies, indicating that they were true members. Since then, hundreds more of these galaxies have turned up in the Coma cluster and elsewhere.
Ultradiffuse galaxies are large like the Milky Way — which is much bigger than most — but they glow as dimly as mere dwarf galaxies. It’s as though a city as big as London emitted as little light as Kalamazoo, Michigan.
More significantly, they have now found that these dim galaxies can be as big and as massive as the biggest bright galaxies, suggesting that, surprise!, there are a lot more stars and mass hidden out there and unseen than anyone had previously predicted.
The competition heats up: A new smallsat satellite company, Sky and Space Global, is planning to launch a 200 nanosat communications constellation for less than $160 million.
More important, they have funded and built the first three, which they will launch in 2017:
The company, located in the U.K., Israel and Australia, has fully funded the first three satellites to precede an initial constellation of 200 nanosatellites. Coined the “Three Diamonds,” the nanosatellites are scheduled to launch as a rideshare aboard a Polar Satellite Launch Vehicle (PSLV) from the Indian Space Research Organization (ISRO) in the second quarter of 2017.
The pilot satellites are to determine the final characteristics of Sky and Space Global’s operational satellites, which are scheduled to begin launching in 2018 via Virgin Galactic’s LauncherOne. Sky and Space Global’s goal is to field a constellation that will eventually become global for low cost telecommunications services such as voice, instant messaging and data forwarding.
What this story illustrates is that the smallsat market is about to become a reality, and in doing so it will shake up the entire geosynchronous communications satellite industry, much as SpaceX has shook up the launch industry. As I’ve noted earlier, these new smallsats suggest that the space industry is splitting, with unmanned Earth-orbit satellites going small and manned capabilities staying large.

The competition heats up: A team of ULA interns, working in their spare time, have successfully launched the largest model rocket every built.
On Sunday (July 24), ULA launched the 50-foot-tall (15.24 meters) Future Heavy rocket out of Fort Carson Army Post, breaking the record for “the largest sport rocket launched anywhere in the world,” according to a statement from ULA. The Future Heavy is also notable because it was built entirely by company interns and their mentors. “We like [our interns] to have a very realistic experience,” ULA President and CEO Tory Bruno told Space.com at the Space Symposium meeting in Colorado Springs, Colorado, last April.
Calling it a “model rocket” really isn’t fair. The thing is big, and really ranks up there with many of the suborbital rockets NASA used to routinely fly out of Wallops Island. That ULA has provided support for this effort again suggests that the leadership of Bruno is reshaping the company into a much more innovative and competitive company.
