Escape velocity on Phobos changes a lot depending on location

November 16, 2018 9:34 am Robert Zimmerman

A new computer analysis of the shape of the gravitational field of the Martian moon Phobos suggests that the escape velocity varies significantly, depending on where you are on the moon’s surface.

Phobos is an odd duck among our solar system’s moons. It’s tiny (a fraction of a percent the size of our own moon) and is shaped like a potato; that weird shape draws gravity to different places, depending on where you are.

All these features make Phobos a challenge to travel on, researchers report in Advances in Space Research. In some places, moving any faster than 5 kilometers per hour would be enough to free you from the moon’s meager gravitational pull, sending you off into space where you’d likely be captured by Mars’s gravity and end up orbiting the Red Planet. The fastest you could travel anywhere on Phobos would be about 36 kilometers per hour, or a little faster than a golf cart, the team finds.

Obviously, this must be recognized for any mission trying to land and explore the moon.

Rocket Lab raises an additional $140 million

November 16, 2018 9:29 am Robert Zimmerman

Capitalism in space: Rocket Lab has raised an additional $140 million in investment capital following its successful first operational launch last week.

The company announced Nov. 15 that it closed a Series E funding round, led by existing investor Future Fund, an Australian sovereign wealth fund. Several other existing investors also joined the round, including Greenspring Associates, Khosla Ventures, Bessemer Venture Partners, DCVC (Data Collective), Promus Ventures and K1W1. One new investor, Accident Compensation Corporation of New Zealand, joined the round.

The Series E round comes after the company raised $75 million in a Series D round in March 2017. The company has now raised more than $288 million to date. Rocket Lab did not disclose the valuation of the latest round, but said it exceeded the “$1-billion-plus” valuation from its Series D round.

In the race to grab the smallsat market, Rocket Lab is far ahead of its nearest competitors, Virgin Orbit and Vector. If I had to rank them at this moment, I would say that Virgin Orbit is second with Vector third.

Defense offers much lower $5 billion Space Force cost

November 16, 2018 9:23 am Robert Zimmerman

The deputy defense secretary yesterday said that the cost for creating a Space Force should be around $5 billion, not $13 billion as proposed by the Air Force.

The cost to create President Trump’s Space Force could be lower than $5 billion and certainly will be in the single-digit billions, Deputy Defense Secretary Patrick Shanahan said at a briefing Thursday, pushing back against Air Force estimates that put the price tag at $13 billion or more.

Shanahan, the lead Pentagon official working on the Space Force, expressed confidence the project would come to fruition — even though Democrats taking over the House have opposed it and the White House has broadly ordered the Pentagon to cut costs.

It appears that he is proposing that the military avoid the creation of a full-fledged new branch of the military and simply reorganize its space bureaucracy into a single office. This would not require Congressional approval, and is also what the military has been considering for the last few years.

Five billion however for an office still seems an ungodly amount of money to me. But then, this is how corrupt Washington functions.

Astronomers identify first progenitor star for Type 1C supernovae

November 15, 2018 3:27 pm Robert Zimmerman

Astronomers have for the first time identified a progenitor star for a Type 1C supernovae.

[The search for supernovae progenitor stars has found] a few pre-supernova stars. But the doomed stars for one class of supernova have eluded discovery: the hefty stars that explode as Type Ic supernovas. These stars, weighing more than 30 times our Sun’s mass, lose their hydrogen and helium layers before their cataclysmic death. Researchers thought they should be easy to find because they are big and bright. However, they have come up empty. Finally, in 2017, astronomers got lucky. A nearby star ended its life as a Type Ic supernova. Two teams of researchers pored through the archive of Hubble images to uncover the putative precursor star in pre-explosion photos taken in 2007. The supernova, catalogued as SN 2017ein, appeared near the center of the nearby spiral galaxy NGC 3938, located roughly 65 million light-years away.

An analysis of the candidate star’s colors shows that it is blue and extremely hot. Based on that assessment, both teams suggest two possibilities for the source’s identity. The progenitor could be a single star between 45 and 55 times more massive than our Sun. Another idea is that it could have been a binary-star system in which one of the stars weighs between 60 and 80 times our Sun’s mass and the other roughly 48 solar masses. In this latter scenario, the stars are orbiting closely and interact with each other. The more massive star is stripped of its hydrogen and helium layers by the close companion, and eventually explodes as a supernova.

As can be seen by the quote above, identifying the star that exploded still leaves much unknown, including whether the star is a single or a binary. Still, they finally have some idea what kind of star erupts in a Type IIC supernovae, which will help constrain the theories for explaining the cause of these explosions.

Note also that this identification will not be confirmed until the supernova itself completely fades in about two years. They might find when that happens that the candidate progenitor is still there, meaning it was not the progenitor of the supernova at all.

SpaceX successfully launches Qatar communications satellite

November 15, 2018 3:19 pm Robert Zimmerman

Capitalism in space: SpaceX today successfully launched a communications satellite for Qatar.

The first stage, previously flown in July, successfully landed on their drone ship. They intend to fly it for an unprecedented third time in the very near future. With this launch SpaceX has tied its record for most launches in a year, 18, which is also the most ever in a single year by a private company.

The leaders in the 2018 launch race:

31 China
18 SpaceX
10 Russia
8 ULA
8 Europe (Arianespace)

China continues to lead the U.S. in the national rankings, 31 to 29.

Sixty documented-as-false anti-Trump news stories

November 15, 2018 9:11 am Robert Zimmerman

Link here. A review of the sources for these stories show them coming mostly from the usual liberal news sources, places like CNN, the New York Times, the Washington Post, MSNBC, etc. I especially like #48:

48. May 28, 2018: The New York Times’ Magazine editor-in-chief Jake Silverstein and CNN’s Hadas Gold shared a story with photos of immigrant children in cages as if they were new photos taken under the Trump administration. The article and photos were actually taken in 2014 under the Obama administration.

Even after it was clearly documented that the fenced facilities were established during the Obama administration and that the Trump administration was simply continuing Obama policy in this area, these news organizations actually ramped up their coverage to make it seem as if Trump was the person who created this policy.

Liberals might wonder why Trump’s support remains strong, and rail against his crude attacks on the liberal press, but the bottom line remains: What he has been saying about the liberal press is largely true. They have stopped doing real reporting and have instead allowed their opposition to a Republican president to turn into blind hatred.

Moreover, Trump’s crude attacks have been a response to the left’s own crudeness and dishonesty, something the left refuses to admit to. And until we see a introspective reassessment by the liberal press, the crude attacks from both sides are only going to get worse.

India to attempt four more launches in 2018

November 15, 2018 8:50 am Robert Zimmerman

The new colonial movement: In outlining the success of yesterday’s GSLV launch, the head of India’s space agency noted that they will attempt to complete four more launches before the end of the year.

Following the missions, Mr Sivan said, in January next, ISRO would launch the Chandrayaan-II mission (lunar lander) which will be the first operational mission of the GSLV-Mk III-vehicle.

Addressing reporters after the successful launch of the second developmental flight GSLV-MkIII-D2 carrying communication satellite GSAT-29, he said, “we have to achieve 10 missions before January.”

“That is six satellite missions as well as four launch vehicle missions. Definitely, the task in front of us is very huge,” he said.

According to him, after Wednesday’s flight, the heaviest launcher of India has completed its development flights and is entering into the operational group of launchers of ISRO, that is along with the PSLV (polar satellite launch vehicle) and GSLV.

Four launches in six weeks would require a launch every week and a half. IF ISRO can do this, they will demonstrate the ability to launch almost weekly, a capability that would place them close to becoming a world power in space.

Scientists admit to many errors in ocean warming paper

November 14, 2018 2:45 pm Robert Zimmerman

The uncertainty of science: The scientists who wrote a much heralded paper a few weeks ago claiming that the oceans are retaining far more heat than previously believed have admitted that their paper has many errors that make its conclusions far more uncertain.

Scientists behind a major study that claimed the Earth’s oceans are warming faster than previously thought now say their work contained inadvertent errors that made their conclusions seem more certain than they actually are.

Two weeks after the high-profile study was published in the journal Nature, its authors have submitted corrections to the publication. The Scripps Institution of Oceanography, home to several of the researchers involved, also noted the problems in the scientists’ work and corrected a news release on its website, which previously had asserted that the study detailed how the Earth’s oceans “have absorbed 60 percent more heat than previously thought.”

“Unfortunately, we made mistakes here,” said Ralph Keeling, a climate scientist at Scripps, who was a co-author of the study. “I think the main lesson is that you work as fast as you can to fix mistakes when you find them.”

The central problem, according to Keeling, came in how the researchers dealt with the uncertainty in their measurements. As a result, the findings suffer from too much doubt to definitively support the paper’s conclusion about how much heat the oceans have absorbed over time. [emphasis mine]

To put it more bluntly, their conclusions are worthless, the data being too uncertain.

When this paper came out two weeks ago I looked at it, and found myself questioning its results. They seemed too certain. Moreover, their work was too perfect for confirming the theory that the oceans are retaining more heat and thus causing the pause in global warming that no global warming model predicted. It fit the model of most climate research these days, unreliable and unconvincing, which is why I did not post it on Behind the Black.

Now, only two weeks later, we find the researchers backing off from their certain conclusions. If anything is a perfect demonstration of confirmation bias, this story is it. These global warming scientists want desperately to prove their theories, and since their models haven’t been working they are desperately searching everywhere they can for explanations. In this case that search led them astray.

The truth is that maybe the climate field should take a step back and reconsider its entire assumptions about carbon dioxide and global warming. They might actually end up doing better science, and thus do a better job at getting us closer to the truth.

A side note: That this paper passed peer review, and was strongly touted by the media and the science community, illustrates once again how much that media and science community has allowed its biases to cloud its vision. This paper should never have been published with these errors. Period.

Scientists discover giant impact crater buried under Greenland ice

November 14, 2018 2:34 pm Robert Zimmerman

Scientists have discovered the existence of a giant impact crater buried under the Greenland ice.

An international team of researchers, including a NASA glaciologist, has discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in northwest Greenland. The crater — the first of any size found under the Greenland ice sheet — is one of the 25 largest impact craters on Earth, measuring roughly 1,000 feet deep and more than 19 miles in diameter, an area slightly larger than that inside Washington’s Capital Beltway.

They think, based on the data, that this crater is very young, one of the youngest known on Earth. At the most is is no more than 3 million years old.

Null result from Spitzer suggests Oumuamua was small

November 14, 2018 1:43 pm Robert Zimmerman

The uncertainty of science: The inability of the infrared Spitzer Space Telescope to detect the interstellar object Oumuamua as it exited the solar system suggests the object is small.

The fact that ‘Oumuamua was too faint for Spitzer to detect sets a limit on the object’s total surface area. However, since the non-detection can’t be used to infer shape, the size limits are presented as what ‘Oumuamua’s diameter would be if it were spherical. Using three separate models that make slightly different assumptions about the object’s composition, Spitzer’s non-detection limited ‘Oumuamua’s “spherical diameter” to 1,440 feet (440 meters), 460 feet (140 meters) or perhaps as little as 320 feet (100 meters). The wide range of results stems from the assumptions about ‘Oumuamua’s composition, which influences how visible (or faint) it would appear to Spitzer were it a particular size.

The new study also suggests that ‘Oumuamua may be up to 10 times more reflective than the comets that reside in our solar system – a surprising result, according to the paper’s authors.

These results fit the models that explain Oumuamua’s fluctuations in speed as caused by the out gassing of material, like a comet. They also do not contradict the recent hypothesis that the object might have been an alien-built light sail.

The simple fact is that we do not have enough data to confirm any of these theories.

Volcanic rivers on Mars

November 14, 2018 12:53 pm Robert Zimmerman

Cool image time! The photo on the right, cropped and reduced to post here, was part of the November image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO). If you click on the image you can see the full resolution picture.

The uncaptioned release webpage is dubbed “Faults in Granicus Valles.” The image itself only shows a small part of Granicus Valles, named after a river in Turkey, that flows down from the estern slopes of the giant volcano Elysium Mons. While far smaller than the four big Martian volcanoes in the Tharsis region to the east and near Marines Valles (which I highlight often), Elysium Mons still outshines anything on Earth at a height of almost 30,000 feet and a width of 150 miles. It sits at about the same northern latitude of Olympus Mons, but all by itself, rising up at the very northern edge of the transition zone between the southern highlands and the northern plains, with the vast Utopia Basin, the second deepest basin on Mars, to the west.

Overview of Elysium Mons and Granicus Valles

Granicus Valles itself is almost five hundred miles long. At its beginning it flows in a single straight fault, but once it enters the northern plains of Utopia Basin it begins to meander and break up into multiple tributaries. The MRO image above shows only a tiny portion in the northern plains, as illustrated by the white box in the overview map to the left.

SuperEarth orbiting Barnard’s Star?

November 14, 2018 11:18 am Robert Zimmerman

The uncertainty of science: Astronomers have discovered a candidate exoplanet orbiting Barnard’s Star, the closest single star to our solar system and the second closest stellar system after Alpha Centauri.

The planet candidate, named Barnard’s star b (or GJ 699 b), is a super-Earth with a minimum of 3.2 Earth masses. It orbits its cool red parent star every 233 days near the snow-line, a distance where water would be frozen. In the absence of an atmosphere, its temperature is likely to be about -150 ºC, which makes it unlikely that the planet can sustain liquid water on its surface. However, its characteristics make it an excellent target for direct imaging using the next generation of instruments such as NASA’s Wide Field InfraRed Survey Telescope (WFIRST, [3]), and maybe with observations from the ESA mission Gaia [4].

The reason I put a question mark in the headline is that this is not the first time a candidate exoplanet has been proposed to orbit Barnard’s Star. In the 1960s astronomer Peter van de Kemp claimed the star had at least one gas giant orbiting it every 24 years. It was later found that the periodic motion variations he measured were due to “to an artifact of maintenance and upgrade work” at the telescope he was using.

The result above has not been confirmed by other means, so they must list this superEarth as a candidate exoplanet. More observations are necessary to confirm it.

Neutron star merger caused gravitational wave?

November 14, 2018 10:17 am Robert Zimmerman

The uncertainty of science: Astronomers now believe that one of the half dozen or so gravitational waves detected by LIGO was likely caused by the merger of two neutron stars.

One of these, GW170817, resulted from the merger of two stellar remnants known as neutron stars. These objects form after stars much more massive than the Sun explode as supernovae, leaving behind a core of material packed to extraordinary densities.

At the same time as the burst of gravitational waves from the merger, observatories detected emission in gamma rays, X-rays, ultraviolet, visible light, infrared and radio waves – an unprecedented observing campaign that confirmed the location and nature of the source.

The initial observations of GW170817 suggested that the two neutron stars merged into a black hole, an object with a gravitational field so powerful that not even light can travel quickly enough to escape its grasp.

While intriguing, this result is uncertain, and based on many assumptions.

Powerful 1972 solar storm detonated ocean mines in Vietnam

November 14, 2018 10:12 am Robert Zimmerman

Scientists studying a powerful 1972 storm have also uncovered a recently released Navy report that showed the storm was powerful enough that it detonated ocean mines off the coast of Vietnam.

On the same day [the storm arrived on Earth], while observing the coastal waters of North Vietnam from aircraft, US Navy personnel witnessed dozens of destructor sea mines exploding with no obvious cause. These mines were airdropped by the US Navy into Vietnamese waters as part of Operation Pocket Money, a mission aimed at blocking supplies from reaching North Vietnamese ports.

The Navy promptly investigated the peculiar explosions, working with the National Academy of Sciences and the National Oceanic and Atmospheric Administration, to conclude that more than 4,000 mine detonations were most likely triggered by the solar storm, Knipp said.

A now declassified report about the mining of North Vietnam from the Chief of Naval Operations at the Mine Warfare Project Office noted, “this was the first example of what happens to a major mining campaign in the face of the vagaries of nature.”

Many of the destructor mines were designed to trigger if they sensed changes in magnetic fields associated with moving ships. Solar activity is known to perturb Earth’s magnetic field, and in early August 1972, the perturbations were likely strong enough to meet the magnetic requirements for detonation, Knipp said.

This proves once again that one must not dismiss any possibility in trying to understand what happens in the universe. Don’t be credulous, but don’t be close-minded either. The universe can surprise you.

Virgin Orbit completes fastest taxi test of LaunchOne

November 14, 2018 9:44 am Robert Zimmerman

Capitalism in space: Virgin Orbit this past weekend completed the fastest taxi test of its LaunchOne smallsat rocket airplane, with LaunchOne attached.

In a tweet posted today, Virgin Orbit said the Nov. 11 ground test revved up the plane, nicknamed Cosmic Girl, to a speed beyond 110 knots (125 mph) on a runway in Victorville, Calif. That’s fast enough to simulate an aborted takeoff. “We also used the day as an opportunity to load real flight software onto LauncherOne for the first time,” the company said.

My 2016 prediction, that Virgin Orbit’s LauncherOne will reach space before Virgin Galactic’s SpaceShipTwo, looks increasingly likely. They had said they wanted to do their first launch by the end of the 2018 summer. Though this did not happen, their launch license [pdf] is effective through December 2019, and it appears they are moving towards that first launch within a few months.

Vector applies for license for launch in Kodiak, Alaska

November 14, 2018 9:35 am Robert Zimmerman

Capitalism in space: Vector has applied for an FAA license for a suborbital test launch in Kodiak, Alaska of its Vector-R smallsat rocket.

The launch is planned to occur no later than April 2019.

Their original suborbital test schedule was supposed to have occurred already, but those were mere verbal announcements. This is more concrete.

Vector does need to get off the ground however. Two years ago it was considered in a close race with Rocket Lab. Now Rocket Lab has pulled far ahead, and Vector might be losing ground to other smallsat launch companies.

India’s GSLV-Mark 3 rocket successfully launches communications satellite

November 14, 2018 9:15 am Robert Zimmerman

The new colonial movement: India today successfully launched a new Indian communications satellite on the third launch of its larger GSLV-Mark 3 rocket.

The Geosynchronous Satellite Launch Vehicle Mk.III, or GSLV Mk.III, is India’s newest and most powerful rocket. After making a suborbital demonstration launch in late 2014, the rocket made its first orbital mission last June when it deployed the GSAT-19 spacecraft.

Wednesday’s launch was designated D2, indicating that it was the rocket’s second developmental launch, however like last year’s flight its payload – GSAT-29 – is a fully operational satellite.

I have embedded a video of the launch below the fold. The launch occurs at about 25 minutes in.

With this success, the fifth launch this year by India, that country will be able to move forward on the January launch by the GSLV of its Chandrayaan-2 lunar mission.

The leaders in the 2018 launch race remains unchanged:

31 China
17 SpaceX
10 Russia
8 ULA
8 Europe (Arianespace)

China continues to lead the U.S. in the national rankings, 31 to 28.

Another private lunar rover unveiled

November 13, 2018 3:19 pm Robert Zimmerman

Capitalism in space: The private start-up company Lunar Outpost today unveiled its tiny 10 kilogram (22 pound) rover, designed to map lunar resources.

The first Prospector was demonstrated driving and drilling in Lunar regolith simulant at the Colorado School of Mines’ new Lunar testbed facility in the Earth Mechanics Institute overseen by the Center for Space Resources. This event marks the first commercial Lunar Prospector publicly tested in the United States.

Evidence of valuable resources on the Lunar surface, such as water, precious metals, and helium-3 have been established by remote sensing on flyby missions around the Moon. This scientific data has been used to create general resource models of the Lunar surface, which now require ground-truthing to establish optimal landing sites and plan future resource extraction operations. Groups of Lunar Outpost Prospectors will map the surface and subsurface resources of the Moon, while autonomously navigating along waypoints and avoiding hazards such as large rocks and craters. These Prospectors can also be teleoperated if needed and can utilize NASA’s Lunar Orbital Platform-Gateway concept as a center of operations.

This is a tiny inexpensive rover, essentially an upgraded drone. Very smart, and efficent. Below the fold is the company’s video of this demo test. The drilling capability is especially impressive.

Their website does not say how much they will charge for this rover, but they also note that it has 5 kilograms of cargo capacity, meaning that they can also offer this to customers.

LSST’s giant coating chamber arrives in Chile

November 13, 2018 2:54 pm Robert Zimmerman

The giant coating chamber that will be used to coat the mirrors for the Large Synoptic Survey Telescope has arrived in Chile.

The Coating Chamber and its associated equipment will share this level with the camera maintenance rooms, the vertical platform lift, and the shipping and receiving area. The Coating Chamber will be used to coat LSST’s mirrors when they arrive on Cerro Pachón, and to re-coat the mirrors periodically during Operations.

LSST will conduct a 10-year survey, and during this period its mirrors will be exposed to the elements each night as the telescope surveys the sky through the open side of the observatory dome. Over time the mirrors will get dusty, and the mirror coatings may develop small blemishes that eventually affect the telescope’s performance. To ensure that LSST continues to collect the sharpest possible images of the night sky, its mirrors will undergo periodic washing and recoating. It’s anticipated that the Primary/Tertiary Mirror (M1M3) will need to be recoated every two years, and the Secondary Mirror (M2) every five years, during the 10-year survey. Both the washing and recoating will be done inside the observatory; special equipment will be used to remove and transport the mirrors from the telescope to the washing station and coating chamber.

LSST will essentially be imaging the entire visible sky nightly, making it possible over time to track sudden events, such as supernovae, as they happen.

Evidence of nitrogen ice glaciers on Pluto

November 13, 2018 2:49 pm Robert Zimmerman

Using data sent back by New Horizons during its fly-by of Pluto scientists now think they have identified land forms created by past nitrogen ice glaciers.

The washboard and fluted terrain … occur at the location on Sputnik Planitia’s perimeter where elevations and slopes leading into the surrounding uplands are lowest, and also where a major tectonic system coincides with the edge of Sputnik Planitia. The low elevation of the area makes it a natural setting for past coverage by nitrogen ice glaciers, as indicated by modeling of volatile behavior on Pluto performed by Dr. Bertrand at Ames.

Through comparison of the washboard and fluted texture with parallel chains of elongated sublimation pits (depressions in the surface formed where ice turns directly into a gas) seen in southern Sputnik Planitia, the ridges are interpreted to represent water ice debris liberated by tectonism of underlying crust. This water ice debris was buoyant in the denser, pitted glacial nitrogen ice that is interpreted to have formerly covered this area, and collected on the floors of the elongated pits. After the nitrogen ice receded via sublimation, the debris was left as the aligned ridges, mimicking the sublimation texture – washboard ridges where deposited on flat terrain, and fluted ridges where deposited on steeper slopes.

This is strange stuff. The solid bedrock here, water ice, will float on the nitrogen ice sitting on top of it. Thus, the material that wants to sublimate away, nitrogen, sometimes has to fight its way past the water ice that has risen to the top of the pile.

To put it mildly, we hardly understand these alien processes. This research is merely a first stab, the first hand-waving.

Fox reporter threatened, chased from bar

November 13, 2018 9:19 am Robert Zimmerman

They’re coming for you next: A Fox news reporter was threatened and then chased from a Brooklyn bar this week, merely because one patron discovered where she works.

Timpf was confronted by a woman, who, after hearing she worked at Fox News, became enraged and began shouting at her in a threatening manner.

“This girl started going nuts on me, screaming at me to get out of the bar. I found her very threatening,” Timpf said of the woman, whom she had never met before. She said she tried to move to another section of the large bar but the young woman followed her while continuing to scream.

The woman, who was visibly intoxicated at the time, was surrounded by a large group of men and women who all stood by and laughed as she harassed Timpf and followed her around the bar. After realizing no one in the group would defend her in what might become a violent situation, Timpf was forced to flee the bar.
“It was super uncomfortable and I didn’t want things to get physical,” she said. [emphasis mine]

It is the audience that counts. One person was bullying this reporter, and everyone else “stood by and laughed.”

Bad times are coming. You will not be defended should you be attacked physically because of your conservative political beliefs. Be prepared.

Earth’s atmosphere cooling as solar minimum arrives

November 13, 2018 8:59 am Robert Zimmerman

The uncertainty of science: With the early arrival of the solar minimum, the Earth’s atmosphere has quickly shown signs of cooling.

New research shows that Earth’s upper atmosphere is responding. “We see a cooling trend,” says Martin Mlynczak of NASA’s Langley Research Center. “High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy. If current trends continue, it could soon set a Space Age record for cold.”

These results come from the SABER instrument onboard NASA’s TIMED satellite. SABER monitors infrared emissions from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air 100 to 300 kilometers above our planet’s surface. By measuring the infrared glow of these molecules, SABER can assess the thermal state of gas at the very top of the atmosphere–a layer researchers call “the thermosphere.”

“The thermosphere always cools off during Solar Minimum. It’s one of the most important ways the solar cycle affects our planet,” explains Mlynczak, who is the associate principal investigator for SABER.

What effect this upper atmosphere cooling will have on the surface climate is somewhat uncertain, though there is a great deal of evidence suggesting the surface climate will cool also.

Is Rocket Lab an American or New Zealand company?

November 13, 2018 8:53 am Robert Zimmerman

Link here. According to Rocket Lab’s own president, his company is American, even though much of its history is based in New Zealand.

When I asked Peter Beck whether his company was Kiwi or American, he didn’t shirk from waving the Stars and Stripes. “Look, we’ve been an American company and proud of it for many years,” he said.

“The New Zealand element is very important and very special to us but we never tried to hide the fact we’re a US company and this is where New Zealand companies go wrong in the fact that if you want to be a large, successful global company, it’s very difficult to be that out of New Zealand.”

ArianeGroup to cut 2300 jobs

November 13, 2018 8:48 am Robert Zimmerman

Capitalism in space: Faced with a significant loss of market share, taken by SpaceX, the European rocket manufacturer ArianeGroup has announced it will reduce its staffing by 2,300 jobs by 2022.

A joint venture by European aerospace company Airbus and the French group Safran, it currently employs 9,000 people in France and Germany. Constructor of the Ariane rockets, the European Space Agency workhorse, ArianeGroup also produces ballistic missiles.

Ariane 5 rockets are soon to be replaced by the Ariane 6 which will be an estimated 40 percent cheaper to make, under pressure in particular from Elon Musk’s SpaceX.

But European buyers have so far ordered only three Ariane 6 rockets ahead of the first scheduled launch in 2020.

The article at the link, produced by a French news service, is somewhat amusing. It repeatedly blames the lack of demand for the Ariane 6 on the U.S. government, which provides business to SpaceX. It doesn’t mention that ArianeGroup’s Ariane 6 rocket meanwhile is being built with government funds from the European Space Agency, and once completed in the 2020s will have a launch price that exceeds that of the Falcon 9 today. No wonder it hasn’t garnered many customers.

In the November image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO) were three images, dubbed by me in the collage above as number one, number two, and number three, showing pits south of Arsia Mons, the southernmost volcano in the chain of three giant volcanoes to the east of Mars’s largest volcano, Olympus Mons, and to the west of the Marineris Valles valley.

The image on the right provides the geographical context of the three pits. They are all south of the volcano on the vast lava flow plains that surround it. The location of pits #1 and #2 is especially intriguing, on the east and west edges of what appears to be a large lava flow that had burst out from the volcano, leaving a large lava field covering a vast area several hundred miles across just to the south. You can also see a similar large lava field to the north of the volcano. Both fields appear to have been formed when lava poured through the breaks created by the fault that cuts through the volcano from the northeast to the southwest.
