An ancient ocean on Ceres?

10:03 am

Two studies released today by the Dawn science team suggest that the spacecraft has found evidence that an ancient ocean once existed on Ceres.

In one study, the Dawn team found Ceres’ crust is a mixture of ice, salts and hydrated materials that were subjected to past and possibly recent geologic activity, and this crust represents most of that ancient ocean. The second study builds off the first and suggests there is a softer, easily deformable layer beneath Ceres’ rigid surface crust, which could be the signature of residual liquid left over from the ocean, too.

Trump Justice Department settles lawsuits over Obama IRS harassment

9:49 am

The Trump administration has come to a settlement with the lawsuits filed by tea party groups over their harassment by the IRS during the Obama administration.

The government apologized Thursday for illegally targeting tea party groups for intrusive scrutiny and agreed to settlements with hundreds of organizations snared in the targeting, bringing to a close one of the more embarrassing episodes of the Obama administration.

Attorney General Jeff Sessions said the IRS owed the groups an apology after years of poor treatment and even longer refusal to concede bad behavior. He placed blame on “the last administration,” saying the targeting that went on under President Obama “was wrong and should never have occurred.”

One of the settlement agreements, filed in federal court in Washington, D.C., officially admits that the IRS singled out groups because of their political beliefs, in defiance of the law. The other settlement, in a class-action lawsuit in Ohio, includes a “generous” payout to more than 400 groups snared, according to a lawyer involved.

The amount of the settlement was not released.

Meanwhile, John Koskinen remains head of the IRS, despite a long documented record of stone-walling and obstruction of justice. If the Trump administration is really sincere about fixing this proglem so that it won’t happen again, why has Trump not fired him?

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 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.

Scientists propose adding smog to atmosphere to fight global warming

9:44 am

What could possibly go wrong? Global warming scientists have proposed injecting sulphate aerosols (another name for pollution) into the upper atmosphere in order to counter their predicted global temperature rise.

Experts are considering ploughing sulphate aerosols into the upper atmosphere which would cause some of the suns rays to be reflected back out into space. This could potentially cool the Earth down and help counter the effects of climate change, scientists say.

The move would also help reduce coral bleaching and help calm powerful storms.

James Crabbe, from the University of Bedfordshire, is leading the study and his initial results suggest the plan could help cool the planet.

This proposal is based on such flimsy science it appalls me that any scientist would even consider it, especially when you think about the unknown consequences.

Rosetta’s capture of a dust jet from Comet 67P/C-G

9:26 am

Dust jet on Comet 67P/C-G

Cool image time! The Rosetta science team has released images and data gathered in July 2016 when the spacecraft successfully observed a dust outburst erupting from Comet 67P/C-G’s surface. The image on the right, slightly reduced in resolution, shows that outburst.

When the Sun rose over the Imhotep region of Rosetta’s comet on July 3, 2016, everything was just right: As the surface warmed and began to emit dust into space, Rosetta’s trajectory led the probe right through the cloud. At the same time, the view of the scientific camera system OSIRIS coincidentally focused precisely on the surface region of the comet from which the fountain originated. A total of five instruments on board the probe were able to document the outburst in the following hours.

As should be expected, the results did not match the models or predictions. The jet, instigated by water-ice just below the surface turning into gas when heated by the Sun, was much dustier than predicted. They have theories as to why, but it appears that no one likes these theories that much.

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 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.


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

More hints that the first SLS launch will be delayed again

9:17 am

Government in action! The head of the Marshall Space Flight Center yesterday once again hinted that the first unmanned launch of SLS/Orion, presently scheduled for late in 2019, could be delayed again.

In September, the agency said in a statement that it would announce a new target date for EM-1 in October, citing the need to account for a range of issues, including progress on the European-built Orion service module and shutdowns at NASA centers from hurricanes in August and September.

However, an update in October is increasingly unlikely. “Within a few weeks, I think [NASA Acting Administrator Robert Lightfoot] intends to codify whatever that date is going to be,” Todd May, director of NASA’s Marshall Space Flight Center, said in remarks at the American Astronautical Society’s Wernher von Braun Memorial Symposium here Oct. 25.

Bill Hill, deputy associate administrator for exploration systems development at NASA, offered a similar assessment. “Probably in the next month, maybe sooner,” he said in an interview.

These hints have been standard operating procedure for announcing SLS’s endless delays for the past decade. First they make hints that a delay might happen, but reassure everyone that it is very unlikely. Then they follow this up later with announcements about how they need more time to accomplish all their goals. By the third announcement they outline a possible new schedule, including some delay but insist that it isn’t likely. Finally, they release the new dates, often as an aside during some other announcement in order to minimize the news.

It should be noted that the new dates have almost never been realistic. NASA has usually known that the new dates are interim, and that further delays will likely require more of this same dance to make them public.

So, here is my prediction: They are preparing us for the fact that the first unmanned flight will likely slip into 2020, which means the first manned flight slips for certain into 2023, as I have been predicting for the past three years.

Saudi Arabia to invest $1 billion in Virgin Galactic and Virgin Orbit

9:05 am

Capitalism in space: Saudi Arabia and Virgin have signed a non-binding agreement for Saudi Arabia to invest $1 billion in Virgin Galactic and Virgin Orbit.

I’m not sure what to make of this press release. The agreement is clearly called “non-binding,” which means Saudi Arabia is not obliged to provide any funds. At the same time, the deal appears to shift power and control of the two Virgin companies to the Arab country, which if successful (a big “if”) would also quickly give Saudi Arabia both a manned and smallsat launching capability.

Why they chose Virgin appears at first baffling, considering that company’s repeated inability to achieve any of its promises. It could be, however, that Richard Branson’s funds are drying up, and that he needed this deal to keep both companies afloat. Saudi Arabia thus saw an opportunity and grabbed it.

Boeing’s Starliner undergoing drop tests

8:53 am

Capitalism in space: Boeing’s Starliner manned capsule yesterday successfully completed the 11th of 14 drop tests in preparation for launch.

The article includes extensive comments by two NASA astronauts who are working with Boeing on these drop tests. I found this quote interesting:

[Sunita] Williams and [Eric] Boe said there are benefits and drawbacks to either type of landing, but they preferred land over water. Williams speaks from experience: She has already made a land landing aboard a Russian Soyuz capsule. “When you land on land, maybe it’s a little bit harder,” Williams said. “But when you’re coming down at high speed, the water’s hard, too.

“Landing on water, if somebody’s right there to rescue you and they know exactly where you’re coming down, that works. And we’ve shown that works with the Apollo program. But, landing on water — I’m a Navy guy, there’s a big ocean out there and it’s a little space capsule and there’s some definite risks to that, too.

“Landing on the Soyuz, you open the hatch, you smell the grass, you’re not in a huge rush to get out or stay in. You know you’re in a solid place and you know you can take your time getting out and the rescue forces will be there eventually, if they’re not there knocking on the door.”

The article also noted that Boeing plans to refurbish each capsule and reuse it up to ten times.

Email proves Obama administration targeted opponents for harassment by the IRS

10:31 pm

Working for the Democratic Party: An email from an IRS agent, recently uncovered by lawyers representing tea party groups in a class action lawsuit, clearly shows that the Obama administration targeted for harassment conservative groups, based solely on their party affiliation.

[T]he April 1, 2011, email from Elizabeth C. Kastenberg, an official in the agency’s exempt organizations division, says it was explicitly the organizations’ politics that landed them on the target list. “These cases are held back primarily because of their political party affiliation rather than specifically any political activities,” Ms. Kastenberg wrote in an alert to other IRS employees, including her supervisor.

Edward Greim, the attorney for NorCal Tea Party Patriots and hundreds of other groups that are part of the class-action lawsuit, said that was a major admission. “What Kastenberg was saying was they have all different activities, and so there’s no ‘political activities’ that cut across this group. Instead, it’s really their political party affiliation they have in common,” he said. [emphasis mine]

In other words, the IRS decided to demand inappropriate information from these Republican organizations, merely because they were Republican, contradicting utterly the claim by the agency that they were only checking to make sure that these groups, based on their activities, should get non-profit status.

FBI informant cleared to testify on Clinton Uranium Russian deal

10:17 pm

The Trump Justice Department has cleared the FBI informant with direct knowledge of the Clinton-Russian uranium bribery scandal.

The informant worked undercover to investigate bribery and intrigue in the Russian nuclear industry during the Obama administration and was, until Wednesday, bound by a gag order from speaking about what he knew. According to sources at the Department of Justice, the informant is now cleared to testify about a wide range of issues including, specifically, the Clinton Foundation. The informant worked undercover to investigate bribery and intrigue in the Russian nuclear industry during the Obama administration and was, until Wednesday, bound by a gag order from speaking about what he knew.

According to sources at the Department of Justice, the informant is now cleared to testify about a wide range of issues including, specifically, the Clinton Foundation. In a statement, DOJ spokesman Ian Prior told media outlets: “As of tonight, the Department of Justice has authorized the informant to disclose to the Chairmen and Ranking Members of the Senate Committee on the Judiciary, the House Committee on Oversight and Government Reform, and the House Permanent Select Committee on Intelligence, as well as one member of each of their staffs, any information or documents he has concerning alleged corruption or bribery involving transactions in the uranium market, including but not limited to anything related to Vadim Mikerin, Rosatom, Tenex, Uranium One, or the Clinton Foundation.”

The article says the informant will testify Wednesday night before Congress, but also notes that it is unclear as yet how or where that testimony will be given. More details about the scandal here.

If this person reveals as much as the news stories have suggested, it could very well finally shatter the protection the press and the left have given the Clinton since Bill Clinton’s problems as president in the 1990s. What I am sensing is that the Democratic Party might possibly be considering throwing the Clintons to the wolves in an effort to keep the wolves off of it.

Then again, I tend to be a wide-eyed optimist.

The first large object identified coming from interstellar space

6:38 pm

Astronomers think they have spotted the first large object to come from beyond the solar system.

Based on its apparent brightness, dynamicist Bill Gray calculates that it would have a diameter of about 160 meters (525 feet) if it were a rock with a surface reflectivity of 10%. “It went past the Sun really fast,” Gray notes, “and may not have had time to heat up enough to break apart.”

Now it’s headed out of the solar system, never to return. It passed closest to Earth on October 14th at a distance of about 24,000,000 km (15,000,000 miles), and astronomers worldwide have been tracking it in the hopes of divining its true nature — especially whether it’s displaying any cometary activity.

…According to Gray, Comet PanSTARRS appears to have entered the solar system from the direction of the constellation Lyra, within a couple of degrees of right ascension 18h 50m, declination +35° 13′. That’s tantalizingly close to Vega — and eerily reminiscent of the plot of the movie Contact — but its exact path doesn’t (yet) appear to link any particular star.

This object entered the solar system moving at 26 km (16 miles) per second. At that speed, in 10 million years it would traverse 8,200,000,000,000,000 km — more than 850 light-years.

Reminds me of a really good science fiction novel I read recently. They should keep an eye on it for as long as they can, just in case it suddenly changes course and settles into a more circular orbit around the Sun. In the unlikely case it does that, it might just be the biggest discovery in history.

Freon leak on U.S. part of ISS?

6:28 pm

A news report today says that an accident in the U.S. portion of ISS caused a freon leak.

The report also said there was a leak of ammonia, and that he crew is not in danger from either leak.

The report is also very vague and sparse with information, and appears to come from the Russians, since it also says that the leaks suggest “systemic problems in the operation of the station’s U.S. segment.”

Today in fascist academia

11:26 am

Time for another update on the growing movement on American campuses to squelch freedom of speech. The stories below highlight some of the more egregious examples since my last update.

Note also that I am making a point to identify the university in every headline I link to. If you have children who are about to pick a college, a quick search here at Behind the Black will tell you where a college stands on the first amendment and free speech.

No one should be surprised that three of these stories come out of California, which in recent years has become increasingly hostile to the concept of dissent.

All is not bad news, however. The Board of Regents that runs the University of Wisconsin two weeks ago approved a new policy that would suspend and expel students who disrupt speeches and presentations on campus.

This tidbit from the story reveals once again which political party today believes in free speech, and which political party does not.

The new Wisconsin policy mirrors Republican legislation the state Assembly passed in June, though the Senate has yet to act on the bill. Regents President John Robert Behling told the board before Friday’s vote that adopting the policy ahead of the legislation shows “a responsiveness to what’s going on in the Capitol, which helps build relationships.”

Republican Gov. Scott Walker appointed all but two of the board’s 18 members. State public schools Superintendent Tony Evers and Wisconsin Technical College System Board President Mark Tyler are automatically regents by virtue of their offices.

Evers, a Democrat running against Walker in next year’s gubernatorial election, cast the only dissenting vote. He accused the regents of sacrificing free speech to curry favor with Republican lawmakers.

Wisconsin students protest Lincoln because “he owned slaves”

9:34 am

The coming dark age: The American Indian student group at the University of Wisconsin-Madison is protesting a statue of Abraham Lincoln because “he owned slaves” and because there were Indian wars during his administration.

The activist group is now demanding a disclaimer be put up saying Lincoln was complicit in the murder of Native Americans.

Why would they be so angry about Lincoln?

“Everyone thinks of Lincoln as the great, you know, freer of slaves, but let’s be real: He owned slaves, and as natives, we want people to know that he ordered the execution of native men,” said one of the protesters.

For a college student to believe that Lincoln owned slaves is to illustrate an appalling level of ignorance. Moreover, the claim that Lincoln “executed” Indians is to also demonstrate an almost incomprehensible ignorance of the history of the American west. The author at the link gives an accurate though simplified history lesson:

During the war, Minnesota was in a state of chaos due to soldiers abandoning their posts and armies moving east to join the main war effort. On top of that, the Office of Indian Affairs was mired in corruption that was exacerbated by wartime negligence. As a result, money promised to the Sioux tribe in Minnesota in exchange for its land wasn’t coming through, and many of its people starved.

This led to a bloody uprising called the “Dakota War,” which the U.S. government eventually put down.

Over 300 Sioux were sentenced to death for connection to the rebellion. Lincoln saw this as extreme, however, and pardoned all but 38 of the alleged perpetrators, whom he believed were guilty of the worst crimes such as rape and murder.

It was the largest mass hanging in American history, but it could have been much worse if not for Lincoln’s compassion. He believed that the Sioux were getting a raw deal, but needed to ensure peace on America’s borders in a time when the future of the United States was seriously in question.

Squiggles on Mars

9:17 am

Squiggles on Mars

Cool image time! The image on the right, reduced and cropped to post here, shows a sand dune slope with numerous squiggly troughs that end either in a small pit or slowly fade away. At first glance one things the troughs were caused by a boulder rolling downhill, but there are no boulders at the base of the slope, and a rolling boulder wouldn’t create so many similar squiggles like this.

The explanation is that the boulders are made of carbon dioxide ice.

Just like on Earth, high-latitude regions on Mars are covered with frost in the winter. However, the winter frost on Mars is made of carbon dioxide ice (dry ice) instead of water ice. We believe linear gullies are the result of this dry ice breaking apart into blocks, which then slide or roll down warmer sandy slopes, sublimating and carving as they go.

The linear gullies exhibit exceptional sinuosity (the squiggle pattern) and we believe this to be the result of repeated movement of dry ice blocks in the same path, possibly in combination with different hardness or flow resistance of the sand within the dune slopes.

For a really entertaining explanation of this process, take a look at the embedded video below the fold.

Lockheed Martin earnings down due to its commercial space divisions

9:00 am

Capitalism in space: Lockheed Martin’s third quarter earnings were down by one percent, partly due to reduced earnings in its commercial space divisions.

While other factors contributed to the drop in earnings, this quote highlights an important detail about the competition in the launch industry:

Reduced profits from Centennial-based rocketmaker United Launch Alliance caused some of LMSS’ decline, the company said. ULA is a joint venture of Lockheed Martin and Boeing Co. LMSS’ share of ULA’s launch-business profits dropped by $20 million to $45 million in the third quarter, the company said.

ULA’s profits dropped by one-third, which suggests that they are continuing to lose business to SpaceX because of its lower launch prices.

Russia to up ISS crew back to three

8:55 am

In order to integrate the new Nauka module, expected to launch in 2019, the Russians plan to increase their crew size on ISS back to three in late 2018.

[L]ong before the Nauka’s arrival, the Russian crew members aboard the ISS will have their hands full with various chores preceding the docking of the 20-ton spacecraft, which will increase the size and mass of the Russian Segment by almost a third. Moreover, once the module is in place, Russian cosmonauts are expected to labor into the 2020 to fully plug all the systems of the new room into their home in orbit. The total time required to integrate Nauka is expected to reach 2,000 work hours, including 11 spacewalks!

The preparations for the addition of the long-awaited module were scheduled to begin less than a year from now on Sept. 8, 2018, with the launch of the three members of Expedition 57 crew aboard the Soyuz MS-10 spacecraft. The launch will mark the first time since October 2016 that a Soyuz will lift more than one Russian cosmonaut.

Nauka is more than a decade behind schedule, which puts it in the same league as SLS and Orion. But then, Nauka, like SLS and Orion, is a government-built project, so no one should be surprised that it has taken so long. The goal isn’t the exploration of space. The goal is to create jobs, even if they don’t accomplish anything for decades.

NanoRacks successfully deploys its largest commercial smallsat from ISS

9:24 pm

Capitalism in space: NanoRacks today successfully deployed its largest commercial smallsat yet from ISS.

NanoRacks Kaber Deployment Program allows for a larger EXPRESS class of satellites to be deployed from the International Space Station, up to 100 kilograms. NanoRacks deploys these Kaber-class satellites currently through the Japanese Experiment Module Airlock, and will shift deployments to the NanoRacks Airlock Module when the Company’s commercial Airlock becomes operational (planned for 2019).

The key here is that NanoRacks is making money providing launch services to smallsats in partnership with ISS and others. They act as the go-between between the smallsat companies and the NASA bureaucracy, thus earning money by simplifying NASA’s generally Byzantine approval and launch process for private satellite companies.

Since 2016 almost a 1000 published papers have challenged the theory of human-caused climate change

9:02 am

Link here. What the author does is quote from numerous scientific papers where they either note the lack of evidence that human activity has caused the recent warming of the climate since the 1600s, or note other natural phenomenon where the evidence of influence is far stronger. Here’s one example:

Rosenblum and Eisenman, 2017

Observations indicate that the Arctic sea ice cover is rapidly retreating while the Antarctic sea ice cover is steadily expanding. State-of-the-art climate models, by contrast, typically simulate a moderate decrease in both the Arctic and Antarctic sea ice covers.

Here’s another, with a link to the actual peer-reviewed published paper:

Blaauw, 2017 [pdf]

This paper demonstrates that global warming can be explained without recourse to the greenhouse theory

He quotes many more, and has found 900 papers since 2016 that challenge the accepted-wisdoms pushed by global-warming theories.

The point here is not to say the climate doesn’t change, or that increased CO2 is not a concern, but to point out that the science is not settled, and anyone who makes that claim is either ignorant, or lying.

Vector’s third suborbital test flight set for January 2018

8:27 am

Capitalism in space: The third suborbital test flight of Vector’s Vector-R rocket has been scheduled for January 2018 in Mohave.

Vector has, to date, performed two test flights of the Vector, both only to very low altitudes. The first took place in May in California’s Mojave Desert and the second in August at the future site of Spaceport Camden on Georgia’s Atlantic coast. A third test, [company head Jim] Cantrell said, is planned for January, back in the Mojave Desert.

He raised a note of caution about that test. “We have a high chance of planting that one in the desert, because it’s using thrust vector control. We’re taking the training wheels off,” he said.

The article is mostly about Vector’s deal to launch from Wallops Island, which I noted last week. Much of that however is public relations that is far from reality. The important thing now is for Vector to finish its test program and prove its rocket can reach orbit.

Timeline of Russian uranium deal and Clinton donations

2:48 pm

Link here. The timeline not only puts the quid pro quo nature of the Russian uranium deal in context, it helps clarify the players and the different parts they played. It appears this deal not only involved giving Russia control of 20 percent of American uranium, that control included the corrupt Kazakhstan government.

All told, the Clintons and the Clinton Foundation appears to have received in the range of $55 million for their help in making the deal happen, all from players who benefited financially from the deal.

Engineers develop new technique to resume drill use on Curiosity

12:27 pm

Engineers have successfully tested a new drill procedure on a duplicate rover on Earth that bypasses the problem in Curiosity’s drill.

The problem with the drill has been its feed mechanism, which pushes the drill bit downward as it drills its hole. The tests with the duplicate rover on Earth have instead had the drill bit fully extended and used the robot arm itself to push downward. It worked, but the problem on Mars is holding the drill bit perfectly straight and not slipping sideways. They are now doing a test with Curiosity to address this.

Curiosity touched its drill to the ground Oct. 17 for the first time in 10 months. It pressed the drill bit downward, and then applied smaller sideways forces while taking measurements with a force sensor. “This is the first time we’ve ever placed the drill bit directly on a Martian rock without stabilizers,” said JPL’s Douglas Klein, chief engineer for the mission’s return-to-drilling development. “The test is to gain better understanding of how the force/torque sensor on the arm provides information about side forces.”

This sensor gives the arm a sense of touch about how hard it is pressing down or sideways. Avoiding too much side force in drilling into a rock and extracting the bit from the rock is crucial to avoid having the bit get stuck in the rock.

Stay tuned for a Mars rover update, coming shortly!

WHO fakes data to claim weedkiller causes cancer

8:43 am

Par for the course: IARC, the agency of the World Health Organization (WHO) that focuses on cancer research, has apparently faked data so that it could make the claim — in opposition to every other published paper in the world — that a commonly used weedkiller causes cancer.

This detail about the man in charge might explain what happened:

The chairman of the IARC sub-group tasked with reviewing evidence of glyphosate’s effect on laboratory animals was Charles Jameson, an American toxicologist. In testimony as part of personal-injury lawsuits against Monsanto in the United States, Jameson told lawyers for Monsanto he did not know when, why or by whom the edits had been made.

Monsanto is facing multiple legal claims in the U.S. from plaintiffs who allege glyphosate gave them or their loved ones cancer. Jameson is an expert witness for the plaintiffs. He did not respond to questions for this article. [emphasis mine]

If you want to read the whole ugly story, go to the second link above. This report cites numerous examples where IARC clearly fudged their reports to hide the fact that their conclusions were consistently debunked by other research.

The glory of Cassini’s Saturn

8:31 am

The glory of Saturn

Cool image time! The image on the right, reduced in resolution to post here, was taken by Cassini on August 17, 2017, one month before the spacecraft dived into Saturn to end its mission.

This view looks toward the sunlit side of the rings from about 19 degrees above the ringplane. The image was taken in green light with the Cassini spacecraft wide-angle camera on Aug. 12, 2017. Pandora was brightened by a factor of 2 to increase its visibility.

The view was obtained at a distance to Saturn of approximately 581,000 miles (935,000 kilometers) from Saturn. Image scale is 35 miles (56 kilometers) per pixel. The distance to Pandora was 691,000 miles (1.1 million kilometers) for a scale of 41 miles (66 kilometers) per pixel.

The moon Pandora can be seen in the full resolution image just beyond the outermost ring near the top of the screen.

SpaceX barge damaged from fire after 1st stage landing

8:22 am

The drone barge used by SpaceX to successfully land a 1st stage during its October 11 launch was subsequently damaged by a fire on board during the return to port.

The exact series of events is unclear, but it is understood the booster leaked some of its residue RP-1 fuel, which flowed along the deck of the ASDS and pooled near the containers at the aft of the drone ship.

The booster then continued post-landing operations, designed to safe the booster ahead of crews boarding the ship to complete the safing process ahead of the trip back to port. At some point shortly after landing there was an ignition of the pooled RP-1, likely via the purging of the Triethylaluminum-Triethylborane (TEA-TEB) that is used as the first stage ignitor. This has to be purged as part of the safing procedures for allowing crew near the rocket. Fire hoses – staged on the deck of the ship – quickly doused the fire. However, the garage containing the robot – nicknamed “Roomba” or “OctaGrabber” (among other names) – was caught in the fire and damaged.

This was confirmed by the lack of the robot in view under the rocket during the ASDS’ return to Port.

It appears they are repairing the damages and that future barge landings will not be affected.
