The pushback against Trump begins

9:59 am

Articles today in the science journals Science and Nature give us a taste of the upcoming resistance by the science community to any policy changes put forth by the new Trump administration.

Both articles assume that the Paris climate agreement is already the law of the land, despite the basic fact that the Senate has not approved it. In fact, if Trump and Congress decide to cut all American ties with it, they can. Right now it is merely something that Obama has agreed to, and under our Constitution, the legalities binding us to that agreement are weak, at best.

This quote from the Science article outlines how the science community plans to structure its resistance:

With oilmen like Harold Hamm, CEO of Continental Resources, and Forrest Lucas, the founder of Lucas Oil, named as potential candidates to lead the Departments of Energy and the Interior, respectively, in a Trump administration, the mostly likely historical analogue for the next few years could be the start of Ronald Reagan’s presidency, when he appointed senior officials who were often hostile to the policies of their own agencies. For example, Reagan’s Secretary of the Interior, James Watt, wanted to sell off public lands and reduce forest protections, and his EPA head, Anne Gorsuch, moved to soften clear air and water rules. Some agency staff fought back, and there were frequent leaks, resignations, and lawsuits. Both Watt and Gorsuch ultimately resigned amidst political chaos, and were replaced by less polarizing appointments. If Trump follows a similar path, “there could be a whole lot of churn,” Victor predicts.

Indeed, Trump may quickly learn the limits of the presidency, Victor adds. “The Oval Office will be a lonely place,” he says, if the White House attempts to make radical changes that agency professional staff fiercely opposes. [emphasis mine]

And then there is this quote from the Nature article:

“Trump will be the first anti-science president we have ever had,” says Michael Lubell, director of public affairs for the American Physical Society in Washington DC. “The consequences are going to be very, very severe.”

Calling Trump “the first anti-science president” is the kind of name-calling that is typical of the left and the Democratic Party. Not only is it a silly statement, based merely on the partisan hatred of Republicans by scientists, almost all of whom are Democratic Party loyalists, it has nothing to do with reality. Scientists have no more right to a blank check from the government than anyone else. They need to justify their research, and show that it is worthwhile. Since the 1990s they have not had to do this, which has resulted in blooming budgets and a lot of questionable results. And I say this as a science guy. Unlike these partisans, however, I also recognize that there is a gigantic amount of needless spending in the science budgets of numerous government agencies. Their budgets have grown significantly since 2000, with little to show for it. It is time to bring that spending under some control.

This is only the first shot across the bow. I have no doubt that the science community plans to link up with the partisan mainstream press to create a full-court press against any policy changes or budget cuts that either Trump or Congress may propose. These people do not respect the concept of democracy, and will resist the will of the public in every way they can.

Decline in sunspots continues

10:26 pm

Late Sunday NOAA posted its monthly update of the solar cycle, covering sunspot activity for October. As I do every month, I am posting it here with annotations to give it context.

October 2016 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.

The sunspot decline continued in October, dropping the sunspot number for the month to below the 2007 low prediction. Though the decline continues to track that low prediction, the sunspot count for November has been even lower, suggesting that the ramp down to solar minimum will continue to under perform that prediction and will arrive at minimum sooner than expected. As I noted last month, this fast decline will also mean that the ending solar cycle will be a both a weak and a short cycle, two phenomenon that in the past never went together. In the past, a short cycle meant the maximum was strong, while a long cycle would correspond with a weak maximum.

The Sun continues to behave in a manner that is unprecedented, and suggests the possibility that a Grand Minimum might be coming.

Largest Texas meteorite ever found by accident on dude ranch

10:13 am

The largest Texas meteorite ever, weighing 760 pounds, has been found on a Texas dude ranch.

The owner found it entirely by accident. It apparently had been there for a long time, but no one had noticed it, mostly because of its weathered appearance that made it appear much like any other boulder. Tests proved beyond doubt, however, that it was a meteorite, an L4 chrondite. It has now been sold to a meteorite collection at Texas Christian University in Ft. Worth.

Curiosity finds a meteorite

6:37 pm

The Curiosity science team have identified and now analyzed a nickel-iron meteorite that Curiosity spotted on October 27.

Scientists of the Mars Science Laboratory (MSL) project, which operates the rover, first noticed the odd-looking rock in images taken by Curiosity’s Mast Camera (Mastcam) at at a site the rover reached by an Oct. 27 drive. “The dark, smooth and lustrous aspect of this target, and its sort of spherical shape attracted the attention of some MSL scientists when we received the Mastcam images at the new location,” said ChemCam team member Pierre-Yves Meslin, at the Research Institute in Astrophysics and Planetology (IRAP), of France’s National Center for Scientific Research (CNRS) and the University of Toulouse, France.

ChemCam found iron, nickel and phosphorus, plus lesser ingredients, in concentrations still being determined through analysis of the spectrum of light produced from dozens of laser pulses at nine spots on the object. The enrichment in both nickel and phosphorus at some of the same points suggests the presence of an iron-nickel-phosphide mineral that is rare except in iron-nickel meteorites, Meslin said.

The find is not unprecedented but it is interesting nonetheless.

TMT consortium picks Canary Islands as alternative site to Hawaii

6:52 pm

Faced with delays from protesters and an Hawaiian government slow-walking its permit process, the consortium building the Thirty Meter Telescope has announced that it will build the telescope on the Canary Islands if it continues to be blocked in Hawaii.

The article does not say when they will make this decision, but based on previous reports, they have to make their decision soon in order to begin construction no later than April 2018.

I fully expect them to abandon Hawaii, since I see no desire by the Hawaiian government to play fair during the new permit hearings. Instead, it seems to me that they are rigging this process so that it will never end.

Saturn from above

9:53 am

Saturn from above.

Cool image time! The image on the right, reduced in resolution to show here, shows Saturn from above as Cassini began re-positioning itself into a higher inclination orbit for its last year of orbit dives near and inside the planet’s rings.

The view looks toward the sunlit side of the rings from about 41 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on July 16, 2016 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 752 nanometers. The view was acquired at a distance of approximately 1 million miles (2 million kilometers) from Saturn. Image scale is 68 miles (110 kilometers) per pixel.

Resonance experiment

6:01 pm

An evening pause: While I am sure there are engineers out there who can explain how the interaction of the vibrator with the plate causes the patterns, I look at this from my more philosophical side, and note how this experiment reveals very simply how the universe is filled with hidden wonders and patterns that challenge us as humans to uncover.

Hat tip Tom Wilson.

More climate fear-mongering

12:27 pm

This article from the journal Nature yesterday, Climate change could flip Mediterranean lands to desert, about a new Science journal paper, is very typical of too much of the climate research and reporting these days.

First, they outline the coming and certain disaster:

Maintaining the historic ranges of the region’s ecosystems would require limiting warming to just 1.5 ºC, by making substantial cuts to the world’s greenhouse-gas emissions, the analysis concludes. Otherwise, the vegetation and ecosystems of the Mediterranean basin will shift as temperatures rise. Increasing desertification in southern Europe is just one of the changes that would result. “Everything is moving in parallel. Shrubby vegetation will move into the deciduous forests, while the forests move to higher elevation in the mountains,” says Joel Guiot, a palaeoclimatologist at the European Centre for Geoscience Research and Education in Aix-en-Provence, France, and lead author of the study.

Then they point out the necessary political solution, which of course requires us to agree to an odious international agreement that will limit our individual freedoms and give more power to international governments:

“I like that they’re doing this comparison across different warming scenarios in line with the Paris agreement, to start to gauge the sensitivity to them,” says Benjamin Cook, a climate scientist at the NASA Goddard Institute for Space Studies in New York City. The study confirms the vulnerability of many ecosystems, and could guide policymakers’ efforts to help natural systems adapt to climate change, says Patrick Gonzalez, principal climate-change scientist at the US National Park Service based at the University of California, Berkeley. “This study shows how essential it is for nations to meet their Paris commitments.”

Only at the very end of the article, almost as an aside, do they note these inconvenient facts about the limitations of the paper (which also happens to be based entirely on computer models):

New Horizons returns the last data from Pluto fly-by

2:47 pm

The New Horizons science team announced today that they have finally received the last bit of data obtained by the spacecraft during its July 14, 2015 fly-by of Pluto.

Having traveled from the New Horizons spacecraft over 3.1 billion miles (five hours, eight minutes at light speed), the final item – a segment of a Pluto-Charon observation sequence taken by the Ralph/LEISA imager – arrived at mission operations at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, at 5:48 a.m. EDT on Oct. 25. The downlink came via NASA’s Deep Space Network station in Canberra, Australia. It was the last of the 50-plus total gigabits of Pluto system data transmitted to Earth by New Horizons over the past 15 months.

Once they have checked this data, they will wipe the spacecraft’s onboard hard drives to prepare for the January 1, 2019 fly-by of Kuiper Belt object 2014 MU69.

New details emerge of Schiaparelli crash site

10:36 am

Schiaparelli crash site

A new high resolution image from Mars Reconnaissance Orbiter’s HIRISE camera, reduced in resolution on the right, confirms that Schiaparelli crashed into the ground on October 19.

The scene shown by HiRISE includes three locations where hardware reached the ground. A dark, roughly circular feature is interpreted as where the lander itself struck. A pattern of rays extending from the circle suggests that a shallow crater was excavated by the impact, as expected given the premature engine shutdown. About 0.8 mile (1.4 kilometers) eastward, an object with several bright spots surrounded by darkened ground is likely the heat shield. About 0.8 mile (1.4 kilometers) south of the lander impact site, two features side-by-side are interpreted as the spacecraft’s parachute and the back shell to which the parachute was attached.

The center insert is a close-up of the impact site on the left, which clearly shows that the lander hit the ground hard, producing impact ejecta. That the rays are somewhat asymmetric also suggests that Schiaparellit hit the ground at an oblique angle.

Birds that can fly practically forever

10:01 am

New research using data loggers tagged to thirteen common swifts has revealed that these birds were capable of remaining airborne for months at a time.

The researchers found that some of the birds made a few brief night landings in winter but remained airborne for 99% of the time. Three birds didn’t touch down once in the entire ten months….“Common swifts have evolved to be very efficient flyers, with streamlined body shapes and long and narrow wings, generating lift force at low cost,” says Anders Hedenström, a study co-author and a biologist at Lund University in Sweden. The birds even eat while airborne, snatching flying termites, ballooning spiders and other aerial insects for in-flight meals.

Hedenström says that common swifts have adapted to a low-energy lifestyle, but his team does not yet know whether the birds sleep while aloft. “Most animals suffer dramatically from far less sleep loss,” says Niels Rattenborg, a neurobiologist at Max Planck Institute for Ornithology in Seewiesen, Germany. “But these birds seem to have found a trick through evolution that allows them to get by on far less sleep.”

The effect of weightlessness on the spine

9:04 am

New observations of astronauts before and after four to seven month long missions to ISS has found the back pain many astronauts experience appears to be caused by significant muscle atrophy.

The MRI scans indicated significant atrophy of the paraspinal lean muscle mass —which plays a critical role in spinal support and movement—during the astronauts’ time in space. The lean muscle, or “functional,” cross-sectional area of the lumbar paraspinal muscles decreased by an average of 19 percent from preflight to immediate postflight scans. A month or two later, only about two-thirds of the reduction had recovered. There was an even more dramatic reduction in the functional cross-sectional area of the paraspinal muscles relative to total paraspinal cross-sectional area. The ratio of lean muscle decreased from 86 percent preflight to 72 percent immediately postflight. At follow-up, the ratio recovered to 81 percent, but was still less than the preflight value.

In contrast, there was no consistent change in the height of the spinal intervertebral discs. Dr. Chang and coauthors write, “These measurements run counter to previous hypotheses about the effects of microgravity on disc swelling.” Further studies will be needed to clarify the effects on disc height, and whether they contribute to the increase in body height during space missions, and to the increased risk of herniated disc disease.

These results are very encouraging, because they indicate that the back problems seen are mostly attributable to weakened muscles, not actual spinal damage, and can therefore be more easily mitigated by new exercises while in orbit.

Aggressive SETI observations of Tabby’s star upcoming

8:29 am

Breakthrough Listen, an effort to listen for radio signals from alien civilizations that, plans to devote significant time this year observing Tabby’s star to see if an alien mega-structures are causing that star’s unexplained dimming.

While Siemion and his colleagues are skeptical that the star’s unique behavior is a sign of an advanced civilization, they can’t not take a look. They’ve teamed up with UC Berkeley visiting astronomer Jason Wright and Tabetha Boyajian, the assistant professor of physics and astronomy at Louisiana State University for whom the star is named, to observe the star with state-of-the-art instruments the Breakthrough Listen team recently mounted on the 100-meter telescope. Wright is at the Center for Exoplanets and Habitable Worlds at Pennsylvania State University.

The observations are scheduled for eight hours per night for three nights over the next two months, starting Wednesday evening, Oct. 26. Siemion, Wright and Boyajian are traveling to the Green Bank Observatory in rural West Virginia to start the observations, and expect to gather around 1 petabyte of data over hundreds of millions of individual radio channels.

Juno successfully completes engine burn with smaller thrusters

7:01 pm

Having successfully left safe mode, engineers had Juno do a 31 minute engine burn on Tuesday to adjust its orbit using its smaller thrusters.

The burn, which lasted just over 31 minutes, changed Juno’s orbital velocity by about 5.8 mph (2.6 meters per second) and consumed about 8 pounds (3.6 kilograms) of propellant. Juno will perform its next science flyby of Jupiter on Dec. 11, with time of closest approach to the gas giant occurring at 9:03 a.m. PDT (12:03 p.m. EDT). The complete suite of Juno’s science instruments, as well as the JunoCam imager, will be collecting data during the upcoming flyby.

That they will definitely collect data during the December 11 flyby means that they are going to delay again the main engine burn that will reduce the spacecraft’s orbit to 14 days, its official science orbit. This also means that they are still uncomfortable firing that main engine. It is also not clear from the press release whether this burn was planned, or was added to compensate for the main engine issues.

The vagueness makes me think that Juno has some serious issues that they haven’t yet told us about.

The storms of Jupiter’s south pole

10:12 am

storms on Jupiter

Cool image time! Even though Juno has been unable to gather any additional data since its first close approach of Jupiter in August because of technical problems, the science team has set up its website to allow the public to download the images produced so far, process those images, and then upload them to the site for the world to see.

The image to the right, reduced in resolution to show here, is one example of the many different processed images produced by interested members of the general public. It highlights the seemingly incoherent storms that are raging at Jupiter’s south pole.

close-up of storms

To the left is a cropped section of the full resolution image. It shows the complex transition zone between the darker polar regions and the brighter band that surrounds it. This chaotic atmospheric behavior is something that no climate scientist has ever seen before. It will take decades of research to untangle and even begin to understand what is happening.

Schiaparelli failure focuses in on altimeter data

9:50 am

The investigation into the landing failure last week of the ExoMars 2016 lander, Schiaparelli, is now focusing on a failure in the spacecraft’s altitude software.

The most likely culprit is a flaw in the craft’s software or a problem in merging the data coming from different sensors, which may have led the craft to believe it was lower in altitude than it really was, says Andrea Accomazzo, ESA’s head of solar and planetary missions. Accomazzo says that this is a hunch; he is reluctant to diagnose the fault before a full post-mortem has been carried out. But if he is right, that is both bad and good news.

European-designed computing, software and sensors are among the elements of the lander that are to be reused on the ExoMars 2020 landing system, which, unlike Schiaparelli, will involve a mixture of European and Russian technology. But software glitches should be easier to fix than a fundamental problem with the landing hardware, which ESA scientists say seems to have passed its test with flying colours. “If we have a serious technological issue, then it’s different, then we have to re-evaluate carefully. But I don’t expect it to be the case,” says Accomazzo.

ISRO begins ground tests of its first lunar lander

9:36 am

The competition heats up: ISRO, India’s space agency, has begun testing the sensors its first lunar lander, Chandrayaan-2, will use to descend safely to the surface.

ISRO Satellite Centre or ISAC, which is the lead centre for the country’s second moon mission, has artificially created eight to ten craters to make the terrain resemble the lunar surface. This terrain is now the test bed for the lunar Lander’s sensors. Between Friday and Monday, a small ISRO-owned aircraft carrying equipment with the sensors flew a few times over these craters to see how well they performed.

Changing seasons on Titan

9:15 am

Since entering Saturn orbit in 2004, Cassini has seen the seasons on Titan shift through half a Saturn year.

As Titan approaches its northern summer solstice, NASA’s Cassini spacecraft has revealed dramatic seasonal changes in the atmospheric temperature and composition of Saturn’s largest moon. Winter is taking a grip on the southern hemisphere and a strong vortex, enriched in trace gases, has developed in the upper atmosphere over the south pole. These observations show a polar reversal in Titan’s atmosphere since Cassini arrived at Saturn in 2004, when similar features were seen in the northern hemisphere.

Sadly, there will not be any spacecraft at Saturn during the second half of this Saturn year. After Cassini ends its mission in 2017 it will likely be many decades before another spacecraft arrives, since at this moment none has even been proposed.

Science conference accepts fake paper

11:30 pm

I’m so glad it was peer-reviewed! A fake physics paper written entirely in gibberish using autocomplete function has been accepted by a science conference.

Christoph Bartneck, an associate professor at the Human Interface Technology laboratory at the University of Canterbury in New Zealand, received an email inviting him to submit a paper to the International Conference on Atomic and Nuclear Physics in the US in November. “Since I have practically no knowledge of nuclear physics I resorted to iOS autocomplete function to help me writing the paper,” he wrote in a blog post on Thursday. “I started a sentence with ‘atomic’ or ‘nuclear’ and then randomly hit the autocomplete suggestions. The text really does not make any sense.”

It only took the conference three hours to review the work and to accept it. They then asked the author to confirm his oral presentation and register for the conference for a mere $1099.

Saturn’s changing north pole

10:38 pm

A comparison of images taken by Cassini in 2012 and then in 2016 of Saturn’s north polar region shows a significant change in color.

Scientists are investigating potential causes for the change in color of the region inside the north-polar hexagon on Saturn. The color change is thought to be an effect of Saturn’s seasons. In particular, the change from a bluish color to a more golden hue may be due to the increased production of photochemical hazes in the atmosphere as the north pole approaches summer solstice in May 2017.

Moon found orbiting one of the larger known Kuiper belt object

6:22 pm

Astronomers have found a moon circling 2007 Or10, one of the Kuiper Belts eight largest objects and the only one as yet unnamed.

Astronomers Gábor Marton and Csaba Kiss (Konkoly Observatory, Hungary), and Thomas Müller (Max Planck Institute, Germany) have identified a moon orbiting 2007 OR10. They spotted it in Hubble Space Telescope images taken in September 2010 as part of a survey of trans-Neptunian objects. Marton announced the discovery this week at a joint meeting of the AAS’s Division for Planetary Sciences and the European Planetay Science Congress.

Although 2007 OR10 itself has been known for almost a decade, only recently have researchers realized that it’s surface is quite dark and therefore that it must be quite sizable, with an estimated diameter of 1,535 km (955 miles). This makes it the third-largest dwarf planet, after Pluto and Eris. It also ranks third for distance — 13 billion km or 87 astronomical units away — drifting among the stars of central Aquarius at a dim magnitude 21.

Of the eight largest Kuiper Belt objects, only Sedna has not yet been found to have a moon.

Something in the Kremlin is jamming GPS

6:14 pm

It appears that any GPS unit that approaches the Kremlin in Moscow can no longer pinpoint accurately its location.

A programmer for Russian internet firm Yandex, Grigory Bakunov, said Thursday his research showed a system for blocking GPS was located inside the Kremlin, the heavily guarded official residence of Russian President Vladimir Putin. Users of GPS have complained on social media in recent months that when they are near the Kremlin their GPS-powered apps stop working or show them to be in Moscow’s Vnukovo airport, 29 kilometers (18 miles) away.

The problem has frustrated those requesting taxis via services such as Uber or looking to catch Pokemons in the popular game played on mobile devices. Large numbers of people running the Moscow marathon last month complained that their jogging apps lost track of how far they had run when they passed the Kremlin.
“I got 40 kilometers added on to my distance. It happened by the Kremlin,” marathoner Andrey Yegorov wrote on Facebook as part of a discussion by runners.

Not surprisingly, the agency in charge of security at the Kremlin declined to comment.

Expansion rate of the universe might not be accelerating

6:06 pm

The uncertainty of science: A new review of the data suggests that the expansion of the universe might not be accelerating as posited based on research done in the 1990s.

Making use of a vastly increased data set – a catalogue of 740 Type Ia supernovae, more than ten times the original sample size – the researchers have found that the evidence for acceleration may be flimsier than previously thought, with the data being consistent with a constant rate of expansion.

The study is published in the Nature journal Scientific Reports.

Professor Sarkar, who also holds a position at the Niels Bohr Institute in Copenhagen, said: ‘The discovery of the accelerating expansion of the universe won the Nobel Prize, the Gruber Cosmology Prize, and the Breakthrough Prize in Fundamental Physics. It led to the widespread acceptance of the idea that the universe is dominated by “dark energy” that behaves like a cosmological constant – this is now the “standard model” of cosmology.

‘However, there now exists a much bigger database of supernovae on which to perform rigorous and detailed statistical analyses. We analysed the latest catalogue of 740 Type Ia supernovae – over ten times bigger than the original samples on which the discovery claim was based – and found that the evidence for accelerated expansion is, at most, what physicists call “3 sigma”. This is far short of the 5 sigma standard required to claim a discovery of fundamental significance.

I am not surprised. In fact, I remain continually skeptical about almost all cosmological theories. They might be the best we have, based on the facts available, but they are also based upon incredibly flimsy facts.

MRO images Schiaparelli on Mars

12:06 pm

before and after Schiaparelli

A comparison of images taken by Mars Reconnaissance Orbiter before and after Schiaparelli’s failed attempt to land on Mars have revealed changes that are likely the lander on the surface. The image on the right is a composite that I’ve made showing the two images. The black spot near the top and the white spot near the bottom are not in the first image.

It is thought that the white spot is likely Schiaparelli’s parachute, while the dark spot is thought to be the lander’s impact point.

The larger dark spot near the upper edge of the enlargement was likely formed by the Schiaparelli lander. The spot is elliptical, about 50 by 130 feet (15 by 40 meters) in size, and is probably too large to have been made by the impact of the heat shield.

The large size of the dark spot suggests that the lander hit the ground hard enough to create this large scar.

Did Viking discover life on Mars?

11:30 am

Link here. The article provides a very detailed review of the conflicting results from the various 1970s Viking lander experiments, one of which strongly suggested the presence of microorganisms.

Overall, these life-detection experiments produced surprising and contradictory results. One experiment, the Labeled Release (LR) experiment, showed that the Martian soil tested positive for metabolism—a sign that, on Earth, would almost certainly suggest the presence of life. However, a related experiment found no trace of organic material, suggesting the absence of life. With no organic substances, what could be, or seem to be, metabolizing?

In the forty years since these experiments, scientists have been unable to reconcile the conflicting results, and the general consensus is that the Viking landers found no conclusive evidence of life on Mars. However, a small minority of scientists argues that the Viking results were positive for life on Mars.

The contradictory Viking results have never been fully explained. Many theories have been proposed, ranging from the chemical to the biological, but none have satisfied anyone.

TMT hearing a fiasco

8:00 pm

The initial hearing in Hawaii for the second permit application of the Thirty Meter Telescope today appears to have been a complete fiasco, designed to extend the proceedings as long as possible, ad infinitum.

Confusion reigned as Thursday’s hearing got underway in a Hilo hotel banquet room. Various telescope opponents complained about the scheduling and location of the hearing. One lawyer wanted to know the process for making objections. More than an hour went by before the first witness, environmental planner Perry White, was called to testify.

All witnesses will be allowed to provide a 10-minute summary of written testimony already submitted. But before White could provide his summary, there were various objections about qualifying him as an expert. Nearly two dozen people— many who are individual telescope opponents who don’t have lawyers representing them — will have a chance to cross-examine each witness.

Cross-examination of White will resume Monday.

It is very clear to me that Hawaii is stalling, designing the hearings so that they will last forever. TMT will never get built in Hawaii. It is time to say bye-bye and go somewhere where knowledge and technology is treasured.

Did Opportunity see Schiaparelli?

9:43 am

Opportunity image of Schiaparelli?

Because Schiaparelli was aimed at a landing site somewhat close to the Mars rover Opportunity, the science team aimed the rover’s panoramic camera at the sky yesterday, taking fourteen pictures in the hope of capturing the lander as it came down. Of those fourteen images, the image on the right, reduced in resolution, is the only one that shows that bright streak in the upper right.

close-up of streak

Though this streak might be an artifact, I do not think so. To the left is a close-up from the full resolution image, showing the streak in detail. That doesn’t look like an artifact. It still could be a meteorite, but I also think that doubtful. The coincidence of a meteorite flashing across the sky at the same exact moment Opportunity is looking to photograph Schiaparelli’s landing is too unlikely.

If this is Schiaparelli, expect a press release from NASA in the next few days.
