How to build a scaled-down version of Curiosity, all by yourself!

9:50 am

JPL has released open-source plans for building a scaled down version of the rover Curiosity at a total cost of only $2,500.

This project is a successor to an earlier educational rover model called “ROV-E,” which received positive responses in schools and museums, NASA said. The Open Source Rover offers a more affordable, less complicated model, and according to agency officials, people can assemble the new model with off-the-shelf parts for about $2,500.

“While the OSR [Open Source Rover] instructions are quite detailed, they still allow the builder the option of making their own design choices,” JPL officials said. “For example, builders can decide what controllers to use, weigh the trade-offs of adding USB cameras or solar panels and even attach science payloads. The baseline design of OSR … will allow users to choose how they want to customize and add to their rover, touching on multiple hardware and software principles along the way.”

I wonder how heavy a home-built rover would be, and whether it could be launched on a Falcon Heavy to Mars.

Next Rocket Lab launch set for November

9:40 am

Capitalism in space: Rocket Lab has now announced its next launch will take place in November, with plans for a second launch one month later.

Rocket Lab stood down from an earlier launch window for It’s Business Time in June 2018, after unusual behavior was identified in a motor controller during pre-launch operations. Initially, it was thought the recycle would be a matter of days, before the decision was made to rollback the vehicle and change out the controller.

…Now Rocket Lab has noted that, following analysis, the motor controllers have been modified and – as such – required new qualification testing ahead of the next launch which won’t take place until November

In a sense this delay and their response to it speaks well of the company. Rather than proceed with another controller, they dug deeper, located a more fundamental problem, and have moved to fix it. And it appears they have done this relatively quickly.

Genesis cover

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"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

Chandrayaan-2 delayed again, until January 2019

9:13 am

The new colonial movement: ISRO, India’s space agency, has revealed that the launch of its lunar rover/lander Chandrayaan-2 has been delayed from October to Janaury 2019.

Dr M Annadurai, Director of U R Rao Satellite Centre confirmed to NDTV that the launch date for Chandryaan-2 “is slipping to 2019” from the initially planned launch in October this year.

Dr Annadurai said that India’s moon mission now aims to land in February and the rocket launch will take place in January next year.

Moreover, since the weight of the Chandrayaan-2 satellite has increased, Dr Annadurai said that now instead of GSLV MK-II, GSLV MK-III will be used. Geo-synchronous Satellite Launch Vehicle MK-III (GSLV MK-III), also called the ‘The Bahubali’, is India’s heaviest rocket that weighs nearly 640 tons and will be used to hoist the Chandrayaan-2 satellite from India’s rocket port at Sriharikota.

It appears that in building the spacecraft they have not been able to keep its weight low enough, and have been forced to switch launch vehicles, with this switch causing the delay.

The article also provides a tidbit of information about the GLSV MK-III rocket, that they have an real name for it, Bahubali. If so, they should use it. It sells much better than GLSV MK-III.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

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.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“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.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Rogue giant exoplanet or brown dwarf discovered about 20 light years away

5:16 pm

Using the Jansky VLA radio telescope astronomers have detected evidence of rogue giant exoplanet or brown dwarf about 20 light years away

Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our Solar System. The object, about a dozen times more massive than Jupiter, is a surprisingly strong magnetic powerhouse and a “rogue,” traveling through space unaccompanied by any parent star.

“This object is right at the boundary between a planet and a brown dwarf, or ‘failed star,’ and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets,” said Melodie Kao, who led this study while a graduate student at Caltech, and is now a Hubble Postdoctoral Fellow at Arizona State University.

The data is not sufficient yet to determine whether this is an exoplanet or a brown dwarf. It is big, and it is floating independent of any other objects, which makes it interesting in of itself.

More problems for Mueller in Manafort trial

9:55 am

The first trial by Robert Mueller’s special council investigation (supposedly about Russia collusion during Trump’s election) is not going well so far for Robert Mueller.

1. The trial of Paul Manafort has nothing to do with Russian collusion. In fact, after more than a year of investigation Mueller has yet to find any evidence of collusion.
2. Mueller might not be able to call his star witness, without which the judge told him he does not have a case.
3. Mueller’s attempt to demonize Manafort for living the high life went over very badly with the judge.
4. And today, the judge called an early recess, after apparently losing patience with the prosecution for its errors and attempts to slip improper testimony to the jury.

In general, the Mueller prosecuting team has looked like a clown show, both in the Manafort case as well as in its case against a Russian company that surprised Mueller by actually showing up in court. I don’t know yet if they will get a guilty verdict in the Manafort case, but to my eye it increasingly looks like they won’t. And if Mueller fails here, his entire investigation, which has appeared like a fraud from the start, will be discredited in plain sight.

Another failed drilling attempt by Curiosity

9:38 am

The second attempt by Curiosity to drill into Vera Rubin Ridge was a failure, the rock once again being too hard using the rover’s new improvised drilling technique.

They are now in search of “softer rock.” The scientists very much want to get at least one drill hole in the hematite unit on Vera Rubin Ridge. However, it does appear that the new drill technique, that uses the robot arm to push the drill bit down as its drills, does not provide enough force for some hard geological features.

The failure to drill is in itself not a complete scientific washout. Knowing the hardness of a rock can tell a geologist a great deal about it. Nonetheless, the Curiosity science team seems determined to find something they can drill into on Vera Rubin Ridge.

Mars dust storm blocks Mars Reconnaissance Orbiter images

9:29 am

In my normal routine to check out the periodic posting of new high resolution images from Mars Reconnaissance Orbiter (MRO), the August 1 update brought what at first was a disturbing surprise. If you go to the link you will see that a large majority of the images show nothing by a series of vertical lines, as if the high resolution camera on MRO has failed.

Yet, scattered among the images were perfectly sharp images. I started to look at these images to try to figure out the differences, and quickly found that the sharp images were always of features in high latitudes, while the blurred images were closer to the equator.

The August 1 image release covered the June/July time period, when the on-going Martian dust storm was at its height. The images illustrate also where the storm was most opaque, closer to the equator.

The next few updates, which occur every three weeks or so, should show increasing clarity as the storm subsides. And the storm is subsiding, according to the latest Opportunity update. The scientists have still not re-established contact with the rover, and do not expect to for at least a month or more, but they are finding that the atmospheric opacity at Endeavour Crater seems to be dropping.

More close-up images of Ceres

9:19 am

Dome and fractures in Occator Crater

Strange image time! The Dawn science team today released a set of new images taken by the spacecraft in its new very close orbit of Ceres. The image on the right is a cropped section of one of those images, and shows some fractures and a dome in Occator Crater. The image was taken from 28 miles altitude, and if you click on it you can see the entire photograph.

What immediately stands out in this image is the strange bright flow on top of the dome. At first glance it looks like someone put a seashell there. In reality I think it is showing us a landslide of bright material flowing downward, towards the top of the image. The flow was significant enough that it piled up as it went down, which is why it created a cliff edge and shadow line at its base.

Everything we see here is influenced by Ceres’s tiny gravity. It is not unusual to see fractures in the floor of a crater, the nature of these fractures and domes is different, and will require a lot of work by scientists to interpret, because of the different environment.

No water as yet detected on Ryugu

9:05 am

The Hayabusa-2 science team today said that their first preliminary survey of Ryugu has yet to detect evidence of water.

The Japan Aerospace Exploration Agency (JAXA) said Aug. 2 that data collected from the space probe showed no water on the boulders scattered on the surface of Ryugu.

Ryugu is a C-type asteroid, which is rich in carbon. Many C-type asteroids are known to contain moisture in their surface boulders, and experts hoped that Ryugu would be one of them.

Hayabusa-2’s visit has just begun. I still expect surprises.

NASA announces crews for first commercial manned launches

9:00 am

NASA has announced the crews for the first commercial manned launches.

Boeing’s crew flight test aboard its Starliner spacecraft, which is targeted to launch in mid-2019, will have Eric Boe, Chris Ferguson and Nicole Mann on board. Boeing’s first post-certification mission will have Josh Cassada and Suni Williams aboard.

SpaceX’s demo mission 2 aboard its Crew Dragon spacecraft, which is targeted to launch in April 2019, will have Bob Behnken and Doug Hurley aboard. The first post-certification mission will be crewed by Victor Glover and Mike Hopkins.

These crews cover the first two manned missions for each spacecraft.

Hat tip Kirk Hilliard.

Two men arrested for making threats against Republican congressmen

2:38 pm

Good news: Police in New York and New Jersey have arrested two different individuals for making threats against Republican Congressmen.

The first amendment allows you to say practically anything, except yelling “Fire!” in a theater and making direct threats of violence against another person. Both of these individuals violated the second restriction. Hopefully they will serve time for the violation.

This story however is important because, while leftist news advocates at CNN whine about being yelled at by Trump supporters, actual threats by the left against the right have been going on now for two to three years, non-stop, without anyone in those leftist news organizations apparently noticing.

New launch dates for commercial crew posted by NASA

2:26 pm

NASA has now released an updated schedule for the first test flights of Boeing’s Starliner and SpaceX’s Dragon manned capsules:

In chronological order:

SpaceX Demo-1 (uncrewed): November 2018
Boeing Orbital Flight Test (uncrewed): late 2018 / early 2019
SpaceX Demo-2 (crewed): April 2019
Boeing Crew Flight Test (crewed): mid-2019

Note once again that this schedule bears no resemblance to the pessimistic schedule put forth by the GAO. That schedule indicated that significant delays could be expected because of NASA’s heavy paperwork requirements.

I fully expect that political needs will force that paperwork to be done much faster than the GAO, or NASA, expects, or even wants. And the increased speed will have little to do with reducing safety.

Landslide on Mars

12:45 pm

Landslide on Mars

Cool image time! The image on the right, cropped and reduced in resolution to post here, was taken by Mars Reconnaissance Orbiter on May 30, 2018. It shows the remains of a landslide where it appears a huge chunk of the cliff face broke off and then flowed downward, pushing ahead of it more material to produce a tongue of debris more than four miles long. (If you click on the image you can see the full photograph.)

The picture invokes a spectacular single event. When the cliff broke off, it hit the ground below it like a rock would in wet beach mud. Like wet sand, the ground was pushed away in a muddy gloppy mess.

Is this terrain wet however? The location of this landslide provides some intriguing geological context. Below are two context images, showing this landslide’s location on Mars.

Federal judge rules New Mexico’s civil forfeiture law unconstitutional

9:59 am

Good news! A federal judge has ruled that New Mexico’s civil forfeiture law is unconstitutional.

Federal judge James O. Browning found that seizing property from those suspected of a crime, even before a legal judgment had been rendered, violated the property owner’s legal right to the presumption of innocence. The law placed the burden on citizens to absolve themselves from crimes of which they’re accused, even if they had not been charged. He also held that the program’s funds collection, which bankrolls its budget, enticed law enforcement officials to work for personal benefit rather than for civilian protection.

“The City of Albuquerque has an unconstitutional institutional incentive to prosecute forfeiture cases, because, in practice, the forfeiture program sets its own budget and can spend, without meaningful oversight, all of the excess funds it raises from previous years,” Browning, who sits on the District Court of New Mexico, wrote in an order Saturday.

Hopefully this is only the beginning. Civil forfeiture, which is really nothing more than theft by government, violates the plain language of the Fifth amendment to the Constitution.That federal and state officials have been able to get away with it for the last few decades in unconscionable.

South Africa’s black government moves to allow it to steal land from whites

9:42 am

Modern leftist philosophy: South Africa’s black government has now begun the process to change its constitution to allow it to take land from property owners without compensation.

The racists aim is to take the land from whites and give it to blacks, much as was done in Zimbabwe.

It’s okay, however, because according to modern leftist thought, blacks cannot be bigoted, and nothing they do is bigoted. They are allowed to commit injustices as reparations for past wrongs.

Expect South Africa to become a hellhole in the coming years.

New York Times hires bigot for its editorial board

9:33 am

The bigoted left: The New York Times yesterday announced the hiring for its editorial board of a woman with a long track record of making bigoted and racist tweets.

A lot more is documented here. The woman very clearly hates whites, is an out-and-out bigot, and if she expressed these same opinions about a minority she would have been fired from whatever job she had previously, in an instant.

But she hates whites, and that’s okay in the warped modern leftist community. I expect the New York Times to rally around her. Update: The New York Times rallies around her.

Private rocket failure in Alaska

9:19 am

Capitalism in space: A suborbital test launch of a private company on July 20 likely failed almost immediately after launch.

On July 20, the California-based company Astra Space carried out a suborbital launch of its “Rocket 1” from the Pacific Spaceport Complex on Kodiak Island in Alaska. The rocket took off in foggy conditions, so there wasn’t much to see, but the launch could still be heard, according to local reporter Gabe Stutman. But other than the fact that Rocket 1 launched, no one seems to know what happened next.

The Federal Aviation Administration (FAA) said, in a statement to SpaceNews, that the rocket “experienced a mishap.” Many have taken this to mean that, at some point after the rocket launched, it failed in some way. But Craig Campbell, president of Alaska Aerospace, which operates the launch site, told SpaceNews that Astra Space is “very pleased” with how the launched turned out.

I must admit that I completely missed this event, when it happened. However, it appears that the company experienced some form of failure, not unlike what happened to the recent launch of Interstellar’s MOMO rocket. Since this is a test launch, even a failure is of value however, as it can tell them what is wrong with their rocket.

Planetary scientists protest use of term “Planet Nine” for unknown planet

9:13 am

A group of planetary scientists have protested the recent use by some of the term “Planet Nine” for the unknown large planet some believe remains undiscovered in an orbit beyond Pluto.

“We the undersigned wish to remind our colleagues that the IAU planet definition adopted in 2006 has been controversial and is far from universally accepted. Given this, and given the incredible accomplishment of the discovery of Pluto, the harbinger of the solar system’s third zone — the Kuiper Belt — by planetary astronomer Clyde W. Tombaugh in 1930, we the undersigned believe the use of the term ‘Planet 9’ for objects beyond Pluto is insensitive to Professor Tombaugh’s legacy.

“We further believe the use of this term should be discontinued in favor of culturally and taxonomically neutral terms for such planets, such as Planet X, Planet Next or Giant Planet Five.”

The planetary scientist community, the people who really should be the ones to determine the proper definition of a planet, has never accepted the IAU planet definition. This protest letter is just more evidence of this fact.

Russian scientist accused of treason fed data to NATO

9:09 am

According to his lawyer the Roscosmos scientists who was arrested two weeks ago has been accused of providing classified data to one of NATO’s member states.

The lawyer did not reveal the specific nation involved. Other reports have suggested the leaked material involved Russia’s hypersonic engine research.

I still can’t help wondering what prompted the arrest, and if it is linked somehow with leaks coming out of the FBI and the Department of Justice in connection with Robert Mueller’s never-ending Russian collusion investigation.

Boeing adjusts Starliner launch schedule after fuel leak during test

8:56 am

Capitalism in space: Yesterday Boeing pushed back its Starliner launch schedule as a result of the fuel leak problem that had occurred during an engine test of the capsule last week.

They now plan the first unmanned test flight around the end of this year, with the first manned flight in the middle of 2019.

As for the fuel leak,

several abort engine valves failed to close properly, causing a leak of toxic fuels. The test article was not damaged and no one was hurt, but the incident required an investigation with support from NASA.

Other reports say that 4 of 8 valves failed to close. There is no explanation about why this happened, but I find it a very strange technical failure. Building valves for spacecraft is not cutting edge design, or I wouldn’t think so.

Tomorrow NASA administrator Jim Bridenstine is going to make an announcement with some official launch dates for both Boeing and SpaceX. We shall see if SpaceX’s schedule gets pushed back as well.

Close-up of bright spot in Occator Crater

Vinalia Faculae in Occator Crater

Cool image time! The Dawn science team today released some new images taken by the spacecraft in its final tight orbit around the dwarf planet Ceres. The image on the right is a cropped section of the full image. It shows some interesting details of part of one of the two bright spots in Occator Crater, dubbed Vinalia Facula, and was taken from a distance of 36 miles.

Other images show small bright spots in another small crater, fractures and interesting patterns in the floor of Occator crater, a dome in Occator Crater suggestive of underground processes pushing up, and other close-ups of its crater walls.

While all of these features are reminiscent of geology on Earth, none are really the same. Ceres’ light gravity and harsh environment, plus its history in the asteroid belt, requires alien processes that only hint at similarities to what we see on Earth.

New York shuts down 7-year-old’s lemonade stand

9:58 am

Fascist New York: Because of complaints by commercial vendors, New York bureaucrats moved to shut down a 7-year-old’s lemonade stand.

Soon-to-be second-grader Brendan Mulvaney ran afoul of government regulators last Friday when vendors at the Saratoga County Fair in upstate Ballston Spa whined to a state health inspector that he had no permit to sell refreshments from his family’s front deck just outside the fairgrounds.

Being just a kid, he was also undercutting their pricey drinks by nearly 90 percent, selling lemonade for just 75 cents — a significant discount from the $7 cups inside the fair. He also peddled $1 snow cones and bottled waters. The vendors griped to a state health inspector doing a routine inspection of the fair, and his next visit was to the Mulvaneys’ home. He promptly ordered the stand shut down, leaving the family shocked.

Note that the stand is on the family’s porch, on private property. The boy has has also been operating it for three years, with no problems.

Essentially, the local vendors used the government as a hammer to smash the competition, even if it was something as innocuous as a child’s lemonade stand. And New York, being a fascist state run by fascist Democrats, immediately moved to do the bidding of those vendors.

The government, embarrassed by this, is now trying to fix it, but they still claim that a permit is required for the stand. How nice of them! In modern New York, no one is allowed to start a business without government permission!

NASA safety panel reviews commercial crew, tries to justify its paperwork demands

9:35 am

Link here. The article describes the results from the quarterly meeting of NASA’s safety panel, which occurred last week, including its concerns about the recent test problems during a launch abort test of Boeing’s Starliner capsule. It also describes the panel’s general satisfaction at the status of SpaceX’s Dragon capsule.

The article however ends with a long screed by one panel member, explaining that the heavy paperwork requirements they are imposing on the two companies is not really paperwork.

“It needs to be noted by everyone, and we’re especially interested in making sure that all of the external stakeholders realize this, that while the concluding process of certification has sometimes been described as a paper process, that is really just a shorthand clarification and in reality it could not be further from the truth,” noted Dr. McErlean.

In reality, the process is as follows. “In a certified design, the design agent – the contractor or partner in this case – performs the design and in the certification plan, the design agent and the certification agency (NASA) agree on the submittal of certification evidence.

“This could be measurements, it can be test data, it can be analysis, but it almost always involves the submittal of detailed technical data, not simply paper descriptions or forms. Sometimes it involves witness testing and sometimes it involves physical inspection. But it almost always wraps around important technical submittals.

Can I translate? The safety panel requires a lot of testing so that a lot of paperwork can be filled out. And while much of this testing is likely to help make the capsule’s safer, most of it seems to me to be make-work, and designed to justify the existence of NASA and its safety panel.

Russian company that builds Proton rocket faces bankruptcy and reorganization

9:25 am

The Russian company that builds Russia’s Proton rocket now faces bankruptcy and reorganization.

By the middle of 2018, due to the dramatically slowed down rate of Proton launches, its manufacturers fell deeper into the red and needed federal funding to stay afloat. According to the official numbers, GKNPTs Khrunichev lost 23 billion rubles in 2017 and asked for a 30-billion infusion of cash from the government.

At the end of June, the Head of Roskosmos Dmitry Rogozin acknowledged an ongoing effort to fix the financial situation at Khrunichev and announced plans to accelerate the switch of the Russian launch operations from the Proton to the Angara family. Ironically, Roskosmos exacerbated the company’s debt with its penalties for missed production deadlines, even though Russian payloads slated to ride those delayed rockets were themselves years behind schedule and GKNPTs Khrunichev had no room to store large rocket components.

In an effort to raise capital, Khrunichev planned to sell a big part of its campus, located in the hyper-valuable real estate area of Moscow, to private developers. In the process, the company would also dramatically reduce its production capacity and cut its personnel in the Russian capital, shifting key manufacturing operations to Omsk, in Western Siberia. In another cost-saving measure, around 200 people were reported to be marked for layoffs at Proton’s launch facilities in Baikonur beginning in the fall of 2018.

The Russian government, rather than allow for competition, is working to prop the company up. So, rather than having new companies appear with new and better ideas, Russia will be saddled with an old company not good at innovating.

NASA rubberstamps Russian engines in Atlas 5 for manned flights

9:18 am

Surprise surprise! NASA has certified the Russian engines used in the Atlas 5 as safe for manned flights.

NASA had been claiming that, because it cannot observe every detail in how Russia builds the engines, it cannot certify them as safe for manned flight. This is, and has been, crap. The Atlas 5, with this engine, has been one of the most reliable rockets ever built.

In truth, what NASA’s bureaucracy was really doing was using these Russian engines as a wedge to slow down Boeing’s first manned flight, mainly because the commercial crew program is threatening NASA past monopoly on U.S. manned flight. Once privately built rockets and manned spacecraft fly, people are suddenly going to realize we don’t really need NASA.
