Crab Nebula

Cool image time! The image on the right, reduced and cropped to show here, was created in November 2012 using a number of different telescopes, both on the ground and in space, to image the Crab Nebula in as much of the entire electromagnetic spectrum as possible.

This image combines data from five different telescopes: The VLA (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-Ray Observatory (X-ray) in purple.

Be sure to check out the full image at the Hubble website. It is packed with fascinating details you need to zoom in to to see.

SLS oxygen tank dome dropped and damaged

May 10, 2017 11:46 am Robert Zimmerman

You can’t make this stuff up. The dome for the oxygen tank for NASA’s SLS rocket has been accidently dropped and has been damaged beyond repair.

No details yet. It appears they can build another dome from available parts, but this will likely cause additional delays to the SLS launch schedule.

Update: More information here.

The damage was limited to the one dome section of the tank, which was not yet welded to the rest of the tank. “Assessments are ongoing to determine the extent of the damage,” she said. Henry said that the incident was classified as a “Type B” mishap. Such a mishap, according to NASA documents, covers incidents that cause between $500,000 and $2 million in damage. No one was injured, she said.

The liquid oxygen tank involved in the incident was a qualification model, intended for testing, and not flight hardware. Henry said it wasn’t immediately clear how long the investigation would take.

Palestinian Authority stops shipping medicine to Gaza

May 10, 2017 11:02 am Robert Zimmerman

They’re such nice people! Because of the political battle between Hamas, running Gaza, and the Palestinian Authority, running the West Bank, the Palestinian Authority has stopped its quarterly shipments of medicine to Gaza.

Palestine Today quotes Dr. Munir Bursh, the pharmacy director at the Ministry of Health in Gaza, saying that the Palestinian Authority has stopped supplying medicines and baby formula to Gaza altogether. “90% of the treatment of cancer patients in the Gaza Strip has stopped due to the lack of the supply of drugs,” he said. Bursh added, “This is reprehensible and very strange, threatening a major health disaster up to the collapse of the health situation in Gaza, because the Ramallah government has been responsible for supplying medicine to Gaza, despite the deficit in the previous years.”

“Whoever made this decision is killing the entire people, and punishing the entire people.” He said that the PA supplies the Gaza Strip with medicines every two months, but it did not send any medicines for three months now.

Hospitals in Gaza are also worried about the closure of the Gaza power plant due to the spat between Hamas and Fatah, saying that they cannot desalinate the water needed for every day purposes.

The last line refers to the decision by the Palestinian Authority to stop paying its Gaza electrical bill, forcing Israel to stop supplying Gaza with electricity.

Japan begins testing new rocket engine

May 10, 2017 8:40 am Robert Zimmerman

Capitalism in space: Japan has begun testing the rocket engine it will use in its next generation rocket.

The H-III will succeed the country’s current H-series rockets, H-IIA and H-IIB. The rocket will use commercially available components and a fuselage that can be mass produced, lowering launch costs to about half of the current price tag of approximately 10 billion yen ($88.6 million). The new, more powerful engine will allow the H-III to carry a midsize to large satellite weighing up to 6.5 tons — 60% more than the H-IIA.

If I understand this correctly, a launch with this new rocket will cost about $45 million, which will make it very competitive with SpaceX. At the same time, it is not as powerful, which means it will not serve the exact same customer base. Instead, its capacity makes it a direct competitor to India’s GSLV Mark III rocket.

SpaceX completes first static fire test of Falcon Heavy core stage

May 10, 2017 1:32 am Robert Zimmerman

Capitalism in space: SpaceX this week successfully completed the first static fire engine test of the core stage of its Falcon Heavy rocket.

In a tweet, the company said that it completed the first static fire of the core stage of the rocket at the company’s McGregor, Texas, test site last week. The company did not disclose the precise date of the test or its duration. The company included in the tweet a video showing about 15 seconds of the test.

The Falcon Heavy uses three Falcon 9 first stages, or cores, along with an upper stage, an approach similar to United Launch Alliance’s Delta 4 Heavy. The two side booster cores for the first launch will be previously-flown Falcon 9 first stages, but the center core will be a new stage, modified to accommodate the side boosters.

The first launch is scheduled for sometime in the late summer, early fall.

The left moves to indoctrinate elementary school kids

May 9, 2017 9:18 am Robert Zimmerman

Fascists: A new leftist movement has begun inserting racial and leftist indoctrination materials into elementary public school materials, teaching kids the evils of racism that are inherent in American society, before they are even aware that different races even exist.

Marxist theorist Paolo Freire advocated in Pedagogy of the Oppressed, that schools be used to inculcate radical values in students so they become agents of social change. Freire held that the so-called dominant pedagogy “silences” poor and minority children and that there is no such thing as a neutral educational system.

Joining Freire in his desire to use the educational system to level institutions is unrepentant communist terrorist and education theorist Bill Ayers, who has long advocated poisoning the minds of the young so they can agitate to fundamentally transform American society. “If we want change to come, we would do well not to look at the sites of power we have no access to; the White House, the Congress, the Pentagon,” he said in 2012. “We have absolute access to the community, the school, the neighborhood, the street, the classroom, the workplace, the shop, the farm.”

The article then describes at length actual examples of leftist and racist indoctrination in a variety of public elementary schools, going on right now. And make no mistake, the educational materials here are outright bigoted in their hatred of whites and American society. I am appalled that American parents are tolerating this.

The city of the future will watch you all the time

May 9, 2017 9:09 am Robert Zimmerman

New computer software is making it possible for computers to quickly analyze the data provided by surveillance cameras, which in turn will allow businesses and government to track and identify city dwellers all the time.

Through partner businesses, Nvidia’s technology is set to take things even further, enabling autonomous aerial systems streaming video back from the sky, security robots driving themselves around looking for trouble spots, and ultra high resolution, super-wide panoramic cameras that capture a whole scene instead of needing to track and follow objects.

And instead of just recording and storing footage, every camera’s output would be constantly analyzed and crunched into useful data points. We’re talking facial recognition, vehicle recognition, and pattern tracking in road and pedestrian traffic.

Clearly this will be useful in a law enforcement and security sense, and several Nvidia partners are working along these lines. BriefCam, for example, is demonstrating technology that tracks individuals and vehicles through security footage, then produces super-quick review videos in which all events in a given time frame can be made to happen in a condensed format where a bunch of them are on screen at once.

It seems to me that this new technology fits very well with the urban leftist culture that runs most American cities these days. These fascist communities, run almost exclusively by Democrats, will cheer this surveillance as a way to protect themselves from bad things, including people with opinions they don’t like. Consider how useful this would have been to Berkeley, for instance, during its recent struggle to keep conservative speakers out of town.

Europe considers a helicopter drone for future Mars missions

The European Space Agency is considering flying a technology demonstration helicopter drone on a future Mars mission.

Note that they don’t yet have the money to build this, and it appears that they don’t yet have a mission to fly it on. What they have done is just completed a preliminary study, which suggests the idea is feasible. They are now lobbying for more cash to move forward.

Georgia governor signs spaceport bill

May 9, 2017 8:50 am Robert Zimmerman

Capitlism in space: The governor of Georgia yesterday signed into law a spaceport liability law that will make that state competitive with other states.

I’m not sure yet how realistic Georgia’s hopes are for a viable spaceport. Vector’s next test suborbital flight is scheduled to occur there, but will other companies shift their business there? I am not sure. Nonetheless, this raises the level of competition, which can never be bad.

Brittle and weak welds on SLS tanks?

May 9, 2017 8:39 am Robert Zimmerman

Government in action! The hydrogen tanks that will be used for the first SLS rocket flight were welded using a technique that NASA has since found to be untrustworthy.

Although the weld strength issue stopped welding the qualification and flight articles of the LOX tank before it could start, the issue wasn’t caught until after both LH2 tanks were welded with the modified pin tool last summer. The implications of the two tanks possibly having below design strength welds disrupted the original, post-weld plans.

The LH2 qualification tank, which will be used for structural testing at Marshall Space Flight Center in Huntsville, Alabama, was welded first and after setup and configuration was taken to Building 451 in December of last year both for proof testing of the welds and to qualify the test facility and procedures for subsequent flight tanks. Hydrogen tanks are proof tested by pressurizing them with nitrogen gas while a hydraulic test rig applies loads to the structure. “We wanted to wring out…the control system – 451 was another building that was made bigger to fit the hydrogen tank,” Doering said. “The control system is all new, the reaction fittings are all new, along with all the actuators. We didn’t want to put the flight asset in there to try to use it for the first time, so [using] the qual[ification] article [first] was also trying to wring out the pressurization and the actuation of the control system in 451.”

Originally, the plan included a test case to pressurize the qualification tank to slightly above flight pressure to help as a part of that “pathfinding” work; however, the discovery that the welds may be below design strength forced plans to be reconsidered.“We couldn’t say with any real degree of certainty that these welds would make it to [flight pressure],” Doering said. “In a pneumatic test, pressurizing it like that, it’s like a balloon…there’s a good portion of the community that thinks it will survive, there’s another portion of the community that says you don’t know enough to be able to say that, [and] there’s another portion of the community that says…’no way.’ [emphasis mine]

This is merely the qualification tank, built to find out if the tank design, which appears to be overly complicated to begin with, will work. The flight tank?

Lower pressure isn’t an option for the LH2 flight tank, which must perform at flight pressures both in testing and in flight. The SLS Program developed and is working on multiple, parallel options for consideration that include repairs and/or replacement of the already-welded flight tank. “We’re looking at use as-is – can I get to the point where I’m comfortable using that flight tank?” Doering said. “The answer to that is probably not, just because the analysis tools don’t exist yet to do this.” [emphasis mine]

They are faced with the likely possibility that they will have to repair the tank, which will likely cause the now 2019 launch date for the first unmanned test to be delayed further.

The rumors that NASA is considering making that first test flight a manned one makes me think that they are considering that decision as a cover for these additional delays. “We need more time to make this work as a manned flight,” NASA management will claim, using that extra time to fix the tanks as well. They will also claim they need more money, as they always do.

Meanwhile, NASA is having trouble building rocket tanks, an item that aerospace engineers figured out how to build half a century ago. Way to go, NASA!

The status of all of Trump’s executive appointments so far

May 8, 2017 4:51 pm Robert Zimmerman

Link here. The article is a very detailed and thorough look at the number of Trump appointments, nominated, approved, or missing, for almost all the major cabinet positions, noting above all the lack of names submitted for many positions.

At the end of Trump’s first 100 days, only 27 of 556 political appointments had been confirmed, as compared with 69 for former President Barack Obama and 35 for former President George W. Bush.

If blame is appropriate, there’s plenty of it to go around. The administration blames Democrats for slow-rolling nominees. But Democrats and some Republicans counter that the White House isn’t sending names quickly enough. And a handful of nominees have taken themselves out of contention, mostly because of their various business interests. Since the president likes hiring business leaders, that’s proving no small problem.

The lack of confirmed appointees means agencies are severely limited in the scope of their policy action, whether it’s enacting changes made by Congress or following through on dozens of executive orders Trump has signed.

What strikes me is the feeling that probably a lot of these people are simply not needed. They are political appointees, given posh government jobs in exchange for their work helping presidents get elected. Almost across the board, the agencies involved are functioning just fine without these appointees in place. Trump can tell these civil servants what he needs done, and they can do it.

At the same time, the inability to get these appointees named and approved speaks volumes about the increasing failure of the federal government to function. They can’t even get political appointees in place, people who really aren’t needed and are really only there to pay back favors. What does this tell us about their ability to accomplish things that must get done?

Sunspot update for April 2017

May 8, 2017 3:53 pm Robert Zimmerman

Today NOAA posted its monthly update of the solar cycle, covering sunspot activity for April. It is posted below, with annotations, as I have done now every month since 2010.

April 2017 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

April showed an uptick in sunspot activity, enough to move the numbers back up above the 2007 low prediction. Nonetheless, activity as the cycle has been ramping down has consistently and generally remained below expectation, and does seem heading to an early arrival of solar minimum, sometime in late 2019 or early 2020, about a year early.

I don’t want to sound like a broken record, as I have written this practically every month since I started these updates in 2010, but this short and weak solar maximum suggests the possibility that we might be facing a grand minimum, where there are no significant sunspots for decades. Some solar scientists think this is coming. Others are much more doubtful. Regardless, we can only wait and watch, while also recognizing that weak solar maximums and grand minimums have in the past consistently coincided with global cool weather. The reasons why this has happened are not yet known, but it has happened nonetheless.

Speak your mind at Duke Divinity School and get threatened

May 8, 2017 10:52 am Robert Zimmerman

Fascism in academia: A department chairman at Duke Divinity School in North Carolina objected to the nature and content in a racial re-education training program, and found himself brought up on charges and has since resigned.

The link contains the full correspondence and history that led to the chairman’s resignation. In order to understand the fascist nature of the school’s actions, it is necessary for you to take the time to read it all, including the comments. Essentially, he raised cogent arguments about why he thought the racial training course was a waste of time and inappropriate, and was immediately accused of racism and harassment, and has since resigned.

As one commenter noted,

I worked at a Christian liberal arts college in the late 80s, early 90s, and even then had to put up with this stuff. Not as bad, but it was in the air. I imagine the good Dr. had simply had enough. Unless you live it, you have no idea how horribly oppressive such an atmosphere is, as the ex-student wrote about. 1984 is alive an well at America’s college, and obviously some, seminary campuses. No, bravo to Dr. Griffiths for having the guts to stand up to the totalitarian lefties at his campus.

My only criticism of this chairman is that he resigned. He should have fought it out, making these fascists defend their positions. Instead, by resigning he has ceded control of the school to them.

Saturn’s north pole hexagon jet stream

Saturn's north polar hexagon jet stream

Cool image time! The image on the right, reduced and cropped to show here, was taken by Cassini in January as it was preparing to head into its final 22 orbital dives between Saturn and its rings. The image shows the gas giant’s north polar, with all its magnificent features. As the press release notes, the north pole was in shadow for the first part of Cassini’s mission, and only in recent years has finally moved into sunlight so that the spaceship can see and image it.

Although the sunlight falling on the north pole of Saturn is enough to allow us to image and study the region, it does not provide much warmth. In addition to being low in the sky (just like summer at Earth’s poles), the sun is nearly ten times as distant from Saturn as from Earth. This results in the sunlight being only about 1 percent as intense as at our planet.

This view looks toward Saturn from about 31 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on Jan. 22, 2017 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 939 nanometers.

Be sure to look at the full image.

NASA may have decided to fly humans on first SLS test flight

May 8, 2017 8:32 am Robert Zimmerman

Doug Messier at Parabolic Arc has a story today suggesting that there are rumors at NASA that the agency has decided that it will put astronauts in Orion for SLS’s first test flight, now tentatively scheduled for sometime in 2019.

At he notes, this will only be the second time in history humans will have flown on a untested rocket, the first being the space shuttle, where they had no choice as the vehicle needed people to fly it.

NASA’s arguments in favor of this manned test flight will probably rest on noting how much of the rocket is based on previously flown equipment. For example, the upper stage for this flight will be a modified Delta upper stage, a well tested and frequently flown stage. The first stage will be made of side-mounted first stage solid rocket boosters that are essentially upgrades of the shuttle’s solid rocket boosters. And the first stage engines are actual shuttle engines salvaged from the shuttle’s themselves. In addition, NASA will note that Orion will have a launch abort system, though it appears that there will be no test of this system prior to the flight.

These arguments don’t carry much weight. The Delta upper stage will also be modified for this flight, and this will be that version’s first use. Similarly, the solid rocket boosters have been modified as well, and this will be their first flight. And as I noted, the Orion launch abort system will not have been tested in flight.

Finally, and most important, the goal of this test flight is to see if these different parts have been integrated together properly. As a unit, none of them has ever flown together. To put humans on such a flight is very foolish indeed.

Messier sums this up quite well:

The flight might come off just fine. But, I fear that NASA’s concern about keeping the program funded, and Donald Trump’s desire for some space spectacular to boost his re-election chances, could combine to produce something very unfortunate.

I pray that people in the Trump administration put a stop to this silliness, as soon as possible.

Trump administration removes members of EPA science advisory board

May 7, 2017 8:34 am Robert Zimmerman

In a move related to Trump’s effort to change policy at the EPA, the administration yesterday is reported to have forced out as many as a dozen members of EPA’s 18-person Board of Scientific Counselors.

At an April meeting, the Board of Scientific Counselors discussed the importance of climate change research at EPA and “the growing need for information on, and understanding of, climate change and responses to its impacts,” according to an agenda. They also talked about the importance of considering climate change as a stressor in areas of non-climate research.

The Trump administration has already sent signals that it does not value some areas of federal research, in particular climate science and work that could lead to further regulation of the fossil fuel and chemical industries. The board had 18 members, including Richardson, who said he knew of at least one other member fired. Departures could reach a dozen, he said.

There is going to be a lot of pigs squealing about this. The big question will be whether the Trump administration will have the courage to stand up to those squeals.

The UAE plan to tow an iceberg from Antarctica for drinking water

May 6, 2017 3:14 pm Robert Zimmerman

The United Arab Emirates (UAE) has a project to tow an iceberg more than 5,500 miles from Antarctica in order to provide that arid nation drinking water for about five years.

The National Advisor Bureau, headquartered in Masdar City, Abu-Dhabi, plans to source the massive blocks of ice from Heard Island, around 600 miles (1000 kilometres) off the coast of mainland Antarctica. It will then transport them around 5,500 miles (8,800 km) to Fujairah, one of the seven emirates which make up the UAE. One iceberg could provide enough for one million people over five years, according to the company.

And the scheme could begin as early as the start of 2018.

SpaceX to launch Bulgarian satellite in June with used first stage

May 5, 2017 8:30 pm Robert Zimmerman

Capitalism in space: SpaceX will fly its second used first stage in June when it launches a Bulgarian communications satellite.

In a statement, BulgariaSat said its BulgariaSat-1 spacecraft is scheduled to launch in mid-June on a Falcon 9 from Cape Canaveral, Florida. The first stage of that Falcon 9 will be the same one that launched 10 Iridium Next satellites from Vandenberg Air Force Base in California in January. Maxim Zayakov, chief executive of BulgariaSat, said the use of a reused first stage lowers the launch price and “makes it possible for smaller countries and companies to launch their own satellites.”

The company did not disclose the price it is paying for the launch, including what discount it is receiving for using a “flight-proven” first stage.

Previously SpaceX had said it would charge about $40 million for a launch using a previously flown first stage, so I would suspect the discount is somewhere around that.

China’s space managers now dominate China’s government

May 5, 2017 2:33 pm Robert Zimmerman

Link here. The story describes how a number of prominent managers from that country’s space program have all been promoted into important political positions throughout the government.

Giving new meaning to the term high-flier, four aerospace engineers have become provincial governors in the past four years. … Until five years ago the quartet worked at either CASTC, a state-owned group that has spearheaded the technological development behind China’s ambitious space exploration programme – producing the country’s rockets, satellites and missiles – or the China National Space Administration, which is in charge of that programme.

In the past, provincial governors were predominantly selected from the ranks of those working in local government or the heads of prominent ministries. The political rise of a group with similar backgrounds has usually been linked to the power of a major faction or influential figure, such as party general secretary Xi.

People who have worked with the former aerospace engineers say the technocrats developed a cocktail of traits that appeared tailor-made to appeal to the current leadership. They did not cook the books, were willing to make necessary but unpopular decisions and were largely untainted by factional allegiances.

Their success also helps explain the increased growth of China’s space program in the past few years. These individuals are all likely to be strong supporters of that space program, and all of them are now very well placed to influence the government in favor of that program.

Trump signs $1 trillion spending bill

May 5, 2017 11:26 am Robert Zimmerman

Trump today signed the $1 trillion continuing resolution, keeping the government well funded, with no significant cuts, through September.

The article included a detail I had not noticed previously. When the bill passed in the House, the only ones who voted against it were 103 Republicans, while the entire Democratic caucus voted for it. In other words, the Republican leadership screwed their own party and allied themselves with the Democrats to pass this big spending bill that cuts nothing and breaks almost every promise the Republicans and Trump made about spending during the election campaign.

The article also has this very revealing quote from Office of Management and Budget Director Mick Mulvaney:

“I think it’s great that the Democrats like the bill. That’s fantastic.”

As I have said repeatedly, the election in November was nothing more than the Democratic primary, with a choice between a radical socialist (Clinton) and an old fashioned liberal Democrat (Trump). We get the government we deserve.

Bezos sells about $1 billion of his Amazon shares

May 5, 2017 8:39 am Robert Zimmerman

Capitalism in space: This past week Amazon CEO Jeff Bezos raised about $1 billion in cash by selling 1 million shares of his stock in Amazon.

Amazon.com Inc. Chief Executive Officer Jeff Bezos sold about $1 billion in company stock as part of a planned divestiture, a month after the world’s third-richest man said he spends about that amount annually on his space exploration company Blue Origin LLC.

Bezos sold 1 million shares from Tuesday to Thursday ranging in price from about $935 to $950 per share, according to a regulatory filing on Thursday. He still owns 79.9 million shares, or about 17 percent of the company, down from 83 million shares at the end of 2015.

What this means for Blue Origin is that Bezos has very deep pockets, and will likely be able to finance the development of its very big New Glenn rocket without outside help. That the company will likely also win contracts along the way for the company’s BE-4 rocket engine will also not hurt Bezos’ financial position.

India’s GSLV rocket successfully launches communications satellite

May 5, 2017 8:28 am Robert Zimmerman

India’s successfully launched a communications satellite early today using its Mark II GSLV rocket.

Friday’s launch, designated GSLV F09, was the fifth flight of the Mark II GSLV which debuted in April 2010. This replaced the Mark I, which first flew in 2001 and made its final flight at the end of 2010, introducing an Indian-developed third stage engine instead of a Russian-built engine flown on the Mark I. With this new cryogenic propulsion system, the GSLV Mk.II is a fully indigenous vehicle.

The GSLV’s service has been marred by concerns over its reliability – to date only half of its flights have been successful – however last September’s launch of INSAT-3DR saw it achieve three consecutive successes for the first time.

This launch success significantly strengthens ISRO’s ability to sell its launch services worldwide. They now have three different rocket configurations, all entirely home built, and all with a string of launch successes.

Senate to ignore House Obamacare replacement, write its own bill

May 4, 2017 10:40 pm Robert Zimmerman

Failure theater: Senate Republicans today said in interviews that they plan to ignore the House Obamacare replacement bill, passed earlier today, and write their own bill from scratch.

A Senate proposal is now being developed by a 12-member working group. It will attempt to incorporate elements of the House bill, senators said, but will not take up the House bill as a starting point and change it through the amendment process. “The safest thing to say is there will be a Senate bill, but it will look at what the House has done and see how much of that we can incorporate in a product that works for us in reconciliation,” said Sen. Roy Blunt, R-Mo.

“We are going to draft a Senate bill,” added Sen. Chuck Grassley, R-Iowa. “That is what I’ve been told.”

I have no faith in what we will get in the end, mainly because it is apparent these guys are not starting from the premise of eliminated the law and its unworkable regulations. Instead, they are proposing, as the House did, to install their own unworkable regulations.

Curiosity’s last dune investigation

May 4, 2017 5:12 pm Robert Zimmerman

As Curiosity moves closer to the very base of Mount Sharp, it is presently making its last investigation of the various types of dunes found at the foot of the mountain.

From early February to early April, the rover examined four sites near a linear dune for comparison with what it found in late 2015 and early 2016 during its investigation of crescent-shaped dunes. This two-phase campaign is the first close-up study of active dunes anywhere other than Earth.

Among the questions this Martian dune campaign is addressing is how winds shape dunes that are relatively close together, on the same side of the same mountain, into different patterns. Others include whether Martian winds sort grains of sand in ways that affect the distribution of mineral compositions, which would have implications for studies of Martian sandstones. “At these linear dunes, the wind regime is more complicated than at the crescent dunes we studied earlier,” said Mathieu Lapotre of Caltech, in Pasadena, California, who helped lead the Curiosity science team’s planning for the dune campaign. “There seems to be more contribution from the wind coming down the slope of the mountain here compared with the crescent dunes farther north.”

The article also included a vague update on the status of Curiosity’s drill, out of commission since its drill feed mechanism had problems moving the drill up and down back in the fall of 2016.

Engineers are assessing how the use of vibration to deliver samples may affect the drill feed mechanism, which is used to move the drill bit forward and backwards. In addition, high winds at the linear-dunes location were complicating the process of pouring sample material into the entry ports for the laboratory instruments.

“A balky brake appears to be affecting drill feed mechanism performance,” said Curiosity Deputy Project Manager Steven Lee, of NASA’s Jet Propulsion Laboratory, Pasadena, California. “In some cases, vibration has been observed to change feed effectiveness, so we’re proceeding cautiously until we better understand the behavior. In the meantime, the engineering team is developing several methods to improve feed reliability.”

What this release does not say is whether they are any closer to solving the problem, or whether the drill is essentially out of business for the reminder of Curiosity’s life. To me, the silence on this question is deafening, and strongly suggests that they have decided the drill cannot be used, for the foreseeable future.
