Pluto on July 11

Pluto on July 11

Another cool image for Monday morning: As the spacecraft zooms towards its Tuesday fly-by, it continues to take images of Pluto, even as the planet rotates. For example, compare today’s image on the right with the one I posted yesterday. You can see some of the same features (the donut-like, crater-like feature is the most obvious), but their positions are different because of the planet’s six-day rotation.

Note also that the row of black spots along the equator show more details. Not unexpectedly, they are not as simple as the early fuzzy images suggested. Unfortunately, we will not get to see even more details, as these features will not be in view during the fly-by.

Update: See this link for a new image of Charon.

More and more to come!

Ceres’ white spots might be salt not water

6:16 pm

The uncertainty of science: The principal investigator of Dawn has indicated that the preliminary data they have gotten of Ceres’ white spots strongly suggests that they are not water but salt.

The mystery is far from completely solved, Russell cautioned. The team failed to get the quality of measurements they wanted in examining the spots, and they’ll have to try again at a closer orbit — like the next planned mapping orbit, which will take them from 2,700 miles over the surface to just 900. The photos taken at that height will also have significantly better resolution, which should further help the team determine what the spots are made of.

But based on the spectral data the team did get, Russell said, the spots “really don’t look like mounds of ice. … The bright spots are probably — like you might find in the desert on Earth — a salt plain where maybe water came out at one time and evaporated,” Russell said.

None of this is confirmed, and won’t be until they lower Dawn’s orbit to get higher resolution images. However, this must wait because they have extended Dawn’s mapping orbit for now as they review the issue that caused the safe mode incident on June 30.

Hawaii officials vote to limit access to Mauna Kea

6:08 pm

Hawaii’s Board of Land and Natural Resources voted 5 to 2 on Friday to restrict access to Mauna Kea.

The rule restricts being within a mile (1.6 kilometres) of the mountain’s access road during certain nighttime hours, unless in a moving vehicle, and prohibits camping gear. It would allow construction to resume on the $1.4 billion Thirty Meter Telescope, the subject of months of protests. Many Native Hawaiians consider the mountain sacred. Camping was already prohibited on the mountain. “We need the tools to keep order on the mountain,” said board member Chris Yuen. “It’s sad that it has come to this point.”

Not surprisingly, the leader of the protesters said they would ignore the rule and continue their overnight protests.

Another new Pluto image

6:02 pm

Pluto geology

Cool image time! The New Horizons science team released another image of Pluto on Friday, this time showing enough details that they can begin to see geological features.

New Horizons’ latest image of Pluto was taken on July 9, 2015 from 3.3 million miles (5.4 million kilometers) away, with a resolution of 17 miles (27 kilometers) per pixel. At this range, Pluto is beginning to reveal the first signs of discrete geologic features. This image views the side of Pluto that always faces its largest moon, Charon, and includes the so-called “tail” of the dark whale-shaped feature along its equator. (The immense, bright feature shaped like a heart had rotated from view when this image was captured.)

“Among the structures tentatively identified in this new image are what appear to be polygonal features; a complex band of terrain stretching east-northeast across the planet, approximately 1,000 miles long; and a complex region where bright terrains meet the dark terrains of the whale,” said New Horizons principal investigator Alan Stern.

Oregon threatens to take home of Christian bakers

11:26 pm

Fascists: Oregon is now threatening to place a lien on the home of the Christian bakers who refused to participate in a same-sex wedding for religious reasons.

The BOLI ruling ordered the mom-and-pop bakers to pay $135,000 to the lesbian couple. They were also slapped with a gag order that prohibits them from speaking publicly about their refusal to participate in or bake wedding cakes for same-sex unions.

And now – they have until July 13 to pay the damages or else face additional fines and a possible lien on their home. “This is intimidation and bullying – that’s exactly what it is,” Klein told me in a telephone interview.“ They are trying to strong-arm me into handing over $135,000 to the two girls and if I win on appeal – they will never pay me back.”

A BOLI spokesman confirmed they sent a standard payment letter to the Kleins’ attorney. “The letter informs them that if we do not hear from them, we may turn the matter over to the Department of Revenue, which can place a lien on real property,” the spokesman told me. BOLI said they would also be willing to accept either a full payment or payment arrangements. “Of course, they can also ask for a stay of enforcement while they pursue their appeal,” the spokesman said.

But there’s a catch. The person who will determine whether or not to stay the order — is BOLI Commissioner Brad Avakian — a vocal supporter of the LGBTQIA movement.

Avakian is the same man who ruled against the bakers and imposed the fines and gag order. Anyone think he will issue a stay of his own order?

I must repeat the obvious: No one is preventing any homosexuals from living their lives as they wish. All these Christians want is the same liberty of conscience.

Persecution of conservatives by the IRS and Wisconsin Democrats linked

5:11 pm

Working for the Democratic Party, nationwide! Newly revealed emails now show that even as Lois Lerner was heading the IRS effort to harass conservatives at the IRS, she had a close email correspondence with the official in Wisconsin who helped prosecutors there run their secret investigation of conservatives that included midnight SWAT raids.

It does appear that Lois Lerner worked to get other Democrats in state governments to use their power, as she was, to squelch the first amendment rights of conservatives.

The incivility and hostility of the Mauna Kea protesters

11:07 am

The management of Mauna Kea has released event logs by both their rangers [pdf] and the visitor center [pdf], outlining the generally hostile and illegal behavior of the TMT protesters during the past four months, including threats of violence against visiters and workers to the mountain.

The news story above does not really give the full flavor of the protesters’ generally rude and hostile behavior. They repeatedly threatened workers and visitors, damaged both existing facilities as well as the natural environment on which they camped illegally, and interfered with others who had come to the mountain to star-gaze or work. The logs also include numerous examples of the protesters exhibiting incredible ignorance about the astronomy on the mountain as well as the Thirty Meter Telescope itself. If you get the chance, read these logs yourself. They clarify for everyone which side stands on the side of civilization and which does not.

Finally there is this important tidbit:

From March 24, 2015 through present, groups of protesters, some up to nearly 200 persons, have sporadically been onsite on the University of Hawaii management lands and DLNR lands on Maunakea. A group of about 10 protesters has maintained a continuous presence day and night. [emphasis mine]

As is usual for protests like this, the actual numbers are miniscule, and are magnified by a press that wants to promote the protesters’ agenda, even though a very large majority does not agree with that agenda.

SpaceX in no hurry to launch 4000 satellite constellation

10:23 am

In the heat of competition: During an interview on July 7, Elon Musk noted that SpaceX’s project to launch a 4,000 satellite communications constellation will be not be hurried.

“A lot of companies have tried it and broken their pick on it,” Musk said in response to an audience question during an appearance at the International Space Station Research and Development Conference here. “We want to be really careful about how we make this thing work, and not overextend ourselves.”… “We’re hopefully going to launch a test satellite next year,” Musk said in Boston, not going into detail about the satellite’s capabilities.

Musk indicated that SpaceX was not in a rush to develop the system. “We’re still in the early stages of a big LEO constellation communications idea,” he said. “I think the long-term potential of it is pretty great, but I don’t want to overplay or overstate things.”

Juno flight plan at Jupiter revised

10:16 am

In preparation for its arrival in orbit around Jupiter in about a year, engineers for the unmanned probe Juno have revised their planned orbital maneuvers.

Following a detailed analysis by the Juno team, NASA recently approved changes to the mission’s flight plan at Jupiter. Instead of taking 11 days to orbit the planet, Juno will now complete one revolution every 14 days. The difference in orbit period will be accomplished by having Juno execute a slightly shorter engine burn than originally planned.

The revised cadence will allow Juno to build maps of the planet’s magnetic and gravity fields in a way that will provide a global look at the planet earlier in the mission than the original plan. Over successive orbits, Juno will build a virtual web around Jupiter, making its gravity and magnetic field maps as it passes over different longitudes from north to south. The original plan would have required 15 orbits to map these forces globally, with 15 more orbits filling in gaps to make the map complete. In the revised plan, Juno will get very basic mapping coverage in just eight orbits. A new level of detail will be added with each successive doubling of the number, at 16 and 32 orbits.

The change will extend the official mission from 15 to 20 months, though I expect that even this will be extended if the spacecraft’s fuel holds out.

NASA names its astronauts for the first Dragon and CST-100 flights

10:04 am

The competition heats up: NASA today named the four government astronauts that will fly on the first manned demo flights to ISS of SpaceX’s Dragon and Boeing’s CST-100.

Bob Behnken, Eric Boe, Doug Hurley and Sunita Williams are veteran test pilots who have flown on the shuttle and the International Space Station. ….

NASA said the four astronauts will train with both companies and have not yet been assigned to flights. Two-person crews will fly the first test flights by each capsule, after they have completed an orbital test flight without people on board. Company proposals anticipate an all-NASA crew flying SpaceX’s Dragon test flight, with Boeing’s CST-100 carrying a split NASA-Boeing crew. Boeing has not yet identified its astronaut.

New radio communications from Philae

9:35 am

On July 9 Philae successfully transmitted data to Rosetta for the first time in more than two weeks.

Although the connection failed repeatedly after that, it remained completely stable for those 12 minutes. “This sign of life from Philae proves to us that at least one of the lander’s communication units remains operational and receives our commands,” said Koen Geurts, a member of the lander control team at DLR Cologne.

The mood had been mixed over the last few days; Philae had not communicated with the team in the DLR Lander Control Center (LCC) since 24 June 2015. After an initial test command to turn on the power to CONSERT on 5 July 2015, the lander did not respond. Philae’s team began to wonder if the lander had survived on Comet 67P/Churyumov-Gerasimenko.

The intermittent nature of Philae’s attempts at communication are puzzling. Normally, they either would have communications or they would not. For good communications to break off like this repeatedly is puzzling. It is almost as if there is a loose wire causing communications to go on and off, which seems an unlikely explanation for this problem.

New image of Pluto and Charon

12:02 am

Pluto and Charon

The New Horizons science team today released a new image showing both Pluto and Charon, and not unexpectedly, they are very different from each other.

A high-contrast array of bright and dark features covers Pluto’s surface, while on Charon, only a dark polar region interrupts a generally more uniform light gray terrain. The reddish materials that color Pluto are absent on Charon. Pluto has a significant atmosphere; Charon does not. On Pluto, exotic ices like frozen nitrogen, methane, and carbon monoxide have been found, while Charon’s surface is made of frozen water and ammonia compounds. The interior of Pluto is mostly rock, while Charon contains equal measures of rock and water ice. “These two objects have been together for billions of years, in the same orbit, but they are totally different,” said Principal Investigator Alan Stern of the Southwest Research Institute (SwRI), Boulder, Colorado.

For a half century, since the first probes left Earth to visit other worlds, the one consistent axiom we have learned from every mission is that no two objects are going to be alike, and that every object out there is going to be incredibly unique. Pluto and Charon, in finishing the human race’s first inventory of the solar system, prove this axiom once again.

A bullseye in space

11:18 am

Cool image time! The science team of the Swift space telescope has released a movie compiled from X-ray images taken of the first outburst from black hole V404 Cygni in 26 years. [link fixed!]

Astronomers say the rings result from an “echo” of X-ray light. The black hole’s flares emit X-rays in all directions. Dust layers reflect some of these X-rays back to us, but the light travels a longer distance and reaches us slightly later than light traveling a more direct path. The time delay creates the light echo, forming rings that expand with time.

Detailed analysis of the expanding rings shows that they all originate from a large flare that occurred on June 26 at 1:40 p.m. EDT. There are multiple rings because there are multiple reflecting dust layers between 4,000 and 7,000 light-years away from us. Regular monitoring of the rings and how they change as the eruption continues will allow astronomers to better understand their nature.

V404 Cygni is located about 8,000 light-years away. Every couple of decades the black hole fires up in an outburst of high-energy light. Its previous eruption ended in 1989.

The animation below the fold is a smaller resolution version of the movie, showing the rings as they expand outward.

Some results from SpaceX’s Dragon launchpad abort test

10:17 am

SpaceX has revealed some of the results from their Dragon launchpad abort test in May, which may explain why they have delayed the launch abort test until next year.

SpaceX engineers are evaluating the results of the May 6 pad abort test, in which the prototype Crew Dragon rocketed away from Cape Canaveral’s Complex 40 launch pad, reached an altitude of nearly one mile, and splashed down under parachutes just offshore in the Atlantic Ocean. Officials said data from the test showed a slight underperformance of the SuperDraco jetpack, and capsule did not reach the top speed and altitude targeted by engineers. But the test was successful by NASA’s standards, and the space agency awarded SpaceX a $30 million milestone payment after data reviews. [emphasis mine]

The article says that the delay is to make sure they are doing a launch abort test with the capsule design they intend to use, rather than an earlier design. I wonder if they also have decided they need more time to tweak their designs after this first test, and thus don’t want to use the capsule they had original planned to use since it has an older design.

Instead, the plan is to use the actual capsule after it has flown to ISS in their unmanned demo test flight of the manned capsule. They will not only be using their in-flight design for the test, this will give them extra time to study the results from the first test and revise the SuperDraco engines.

Watch Opportunity’s full journey on Mars, in 8 minutes

9:54 am

The science team for the Mars rover Opportunity have released an 8-minute movie compiled from the rover’s hazard-avoidance cameras. Enjoy!

One comment: There is a long stretch of territory south of Albuquerque, New Mexico called Jornada de Muerto, which means “Journey of Death” in English. It gets its name from its lack of water or life. This video makes that stretch of land look like a water park, strongly highlighting the utter barrenness of the Martian surface.

Best image yet of Pluto

9:29 am

Pluto

Very cool image time! The New Horizons science team today released [link fixed] their best image yet of Pluto, taken on July 7 immediately following the spacecraft’s recovery from safe mode.

This view is centered roughly on the area that will be seen close-up during New Horizons’ July 14 closest approach. This side of Pluto is dominated by three broad regions of varying brightness. Most prominent are an elongated dark feature at the equator, informally known as “the whale,” and a large heart-shaped bright area measuring some 1,200 miles (2,000 kilometers) across on the right. Above those features is a polar region that is intermediate in brightness.

For the first time these features look like actual surface areas on a planet, not fuzzy blobs. We are still seeing Pluto like we saw all planets prior to the space age, but at least now we know what we are looking at.

A Democratic senator admits she doesn’t believe in free speech

9:52 am

In a television interview Senator Tammy Baldwin (D-Wisconsin) insisted that the first amendment does not apply to individuals, and that the government thus has the right to limit both their speech and religious freedoms.

Her position is that the first amendment only protects institutions. This despite the clear wording of the amendment itself, which simply says

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

I don’t see any distinction made between institutions or individuals. Moreover, the courts have repeatedly ruled that these freedoms apply to everyone, individuals, institutions, everyone. Someone with even the slightest knowledge of history, both American, British, and that of all of western civilization, should also know that the battle for liberty of conscience was a battle to expressly give individuals that freedom, not institutions.

Interestingly, the article notes that in another context Baldwin has also said that she doesn’t believe it right that the first amendment protects institutions. She was part of the Democratic Party effort in the Senate in 2013 to repeal the first amendment to allow Congress the right to limit the speech of corporations.

So, to sum up, she thinks individuals aren’t given first amendment rights by the first amendment, and that the institutions that do should be denied those first amendment right as well. Sadly, her position appears to becoming more popular both with Democratic elected officials as well as the public that votes for them.

Oregon bakers raise $200K from supporters

9:24 am

The bakers that the state of Oregon is attempting to bankrupt and gag for opposing same-sex marriage have raised $200K from supporters.

The State of Oregon has failed in its attempt to bankrupt Aaron and Melissa Klein for the crime of declining to bake a cake – as the preposterous $135,000 fine it levied was no match for the willingness of good people to help out the Kleins and their now exclusively online business, Sweet Cakes by Melissa. Through a campaign via Continue to Give, people who still respect both faith and freedom have responded to the following appeal by contributing more than $200,000.

There are two aspects of this story that are important. First, the bakers are defying the state’s order. Though their physical business has closed, they now have an online business. Second, though Go Fund Me decided recently to ban fund-raising drives that try to help Christians under attack by the homosexual fascist community, another on-line funding-raising site has appeared to replace it.

Both suggest that the rule of the leftwing state religion is going to be challenged.

Dance of the stars

8:51 am

Astronomers have found a stellar system made up of five stars, two binary systems orbiting each other, with a fifth star orbiting one of the stars in one of the binaries.

Co-author Dr Markus Lohr, from the Open University, told BBC News that these contact binaries were stars that orbit so closely they share an outer atmosphere. The other star pair – a detached binary – has a separation distance of some three million km. The two binaries orbit in the same plane at a distance of 21 billion km.

Follow-up observations of different wavelengths of light coming from the star system uncovered a fifth star, which is linked to the detached binary star. “This is a truly exotic star system. In principle there’s no reason why it couldn’t have planets in orbit around each of the pairs of stars. Any inhabitants would have a sky that would put the makers of Star Wars to shame,” Dr. Lohr said. “There could sometimes be no fewer than five Suns of different brightnesses lighting up the landscape.”

Dr. Lohr is being a bit extravagant. Though planets are a possibility here, I suspect it very unlikely that they are habitable.

A New Horizons map of Pluto

11:54 pm

New Horizons map of Pluto

Cool image time! The New Horizons science team today released their best global map of Pluto, as seen so far.

The center of the map shows the area that New Horizons will see close-up during the fly-by.

The elongated dark area informally known as “the whale,” along the equator on the left side of the map, is one of the darkest regions visible to New Horizons. It measures some 1,860 miles (3,000 kilometers) in length. Directly to the right of the whale’s “snout” is the brightest region visible on the planet, which is roughly 990 miles (1,600 kilometers) across. This may be a region where relatively fresh deposits of frost—perhaps including frozen methane, nitrogen and/or carbon monoxide—form a bright coating.

Continuing to the right, along the equator, we see the four mysterious dark spots that have so intrigued the world, each of which is hundreds of miles across. Meanwhile, the whale’s “tail,” at the left end of the dark feature, cradles a bright donut-shaped feature about 200 miles (350 kilometers) across. At first glance it resembles circular features seen elsewhere in the solar system, from impact craters to volcanoes. But scientists are holding off on making any interpretation of this and other features on Pluto until more detailed images are in hand.

Some of these features will not be resolved much clearer than this, as Pluto’s day is six Earth days long, and will thus not be visible any longer to the spacecraft during its last week approach. In addition, much of the southern hemisphere will also not be imaged at all, as the planet’s inclination puts much of that hemisphere out of view entirely.

Nonetheless, we will see a great deal that has never been seen before. Stay tuned!

Musk makes first extended public comments since Falcon 9 failure

11:43 pm

In the heat of competition: Elon Musk on Tuesday made his first detailed public comments about the Falcon 9 accident, the on-going investigation, and the aftermath.

Musk hopes to release more details on the failure by the end of this week after further data analysis and engineering reviews. “At this point, the only thing that’s really clear was there was some kind of over-pressure event in the upper stage liquid oxygen tank, but the exact cause and sequence of events, there’s still no clear theory that fits with all the data,” Musk said. “So we have to determine if some of the data is a measurement error of some kind, or if there’s actually a theory that matches what appear to be conflicting data points.”

He also had no word on when launches would resume.

New Horizons team proposes cool names for Charon and Pluto features

11:39 pm

In anticipation of their discovering many previously unseen features on both Pluto and Charon, the New Horizons science team released today a proposed list of names, including “Kirk”, “Spock”, and many other fictional science fiction characters.

Many of these suggestions were proposed by the public. Personally, I prefer the part of their proposal where they suggest naming features after real people, like Lewis Carroll and Arthur Clarke.

IRS defies judge’s court order in Lerner email scandal

4:42 pm

Contempt for the law: The IRS and the Obama administration today directly defied the ruling of a federal judge, who — faced with their stonewalling — had ordered them to release 1800 Lois Lerner emails to the court each Monday.

It appears to me that the IRS and the Obama administration are doing whatever they can to obstruct this investigation and to prevent these emails from ever being seen by the public. This also strongly suggests that there are some real bombshells in those emails, including evidence that there was a blatent effort by the White House, the IRS, and Democratic members of Congress to use the IRS to harass and destroy their political opponents.

I am waiting for this judge to finally show some real backbone and declare several Obama and IRS officials in direct contempt of the court and then have them arrested and imprisoned. Until he does, the Obama administration is going to continue to thumb its nose at him, and the law.

The IRS and Obama administration planned to criminally prosecute its opponents

11:16 am

Working for the Democratic Party: New Justice Department documents released today show that in 2010 the Obama administration and the IRS were conspiring to criminally prosecute opponents of the Obama administration.

Judicial Watch today released new Department of Justice (DOJ) and Internal Revenue Service (IRS) documents that include an official “DOJ Recap” report detailing an October 2010 meeting between Lois Lerner, DOJ officials and the FBI to plan for the possible criminal prosecution of targeted nonprofit organizations for alleged illegal political activity.

The newly obtained records also reveal that the Obama DOJ wanted IRS employees who were going to testify to Congress to turn over documents to the DOJ before giving them to Congress. Records also detail how the Obama IRS gave the FBI 21 computer disks, containing 1.25 million pages of confidential IRS returns from 113,000 nonprofit social 501(c)(4) welfare groups – or nearly every 501(c)(4) in the United States – as part of its prosecution effort. According to a letter from then-House Oversight Committee Chairman Darrell Issa (R-CA) to IRS Commissioner John Koskinen, “This revelation likely means that the IRS – including possibly Lois Lerner – violated federal tax law by transmitting this information to the Justice Department.”

This bears repeating: It is illegal for the IRS to give the confidential tax returns of citizens to anyone, including the Justice Department. Worse, having done so the IRS has given the very partisan Obama administration a giant treasure-trove of data it can use to smear and destroy its opponents.

Study finds electric cars more environmentally damaging than gas guzzlers

10:57 am

Surprise, surprise! A new study has found that in many cases electric cars actually do more damage to the environment that gasoline-run vehicles.

The study has a lot of uncertainties, and is based largely on statistical analysis, which I always find suspect. In addition:

The study’s biggest caveat, acknowledged by the researchers, is that they don’t consider a full “lifecycle” analysis of emissions—so things like making the car, drilling for oil, or transporting coal aren’t included in the environmental costs. Some previous work has found that EVs are cleaner than gas cars when you consider the totality of impacts; others have found that’s only true if the power grids that charge EVs are also clean.

Notice how they also don’t mention any of the environmental costs for making the batteries and components of an electric car. I wonder why.

Nonetheless, this study illustrates again why we should never rely on the opinions of politicians in these matters. They know less than nothing, and always base their policy on raw, simplistic emotions rather than complex knowledge. Better to let freedom, and the market decide. It always looks for the most efficient way of doing things, which in the end is always going to be better for the environment.
