Terraced mesa inside depression

Cool image time! The photo to the right, cropped and reduced to post here, was taken on July 1, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a very puzzling terraced mesa inside an enclosed depression or sinkhole (the western half of which can be seen in the full image).

What caused that mesa? A first scan of the image and the data suggests we are looking at sinkage related to the melting of an underground ice table. The latitude here is 34 degrees south, just far enough away from the equator for glacial activity to be possible. Moreover, the small circular depression in the upper right of the image strongly suggests an impact crater into slushy material. The implication is that this depression is the result of the melting or sublimation of underground ice, leaving behind a mesa that is made of solider stuff.

Another possibility is that the terraced mesa is actually the remains of glacial material. In the full image features inside other nearby depressions are terraced also, but are also much more reminiscent of glacial features found in many craters in the mid-latitudes. The depression is also close to the headwaters of Reull Valles, a meandering canyon where many images have shown glacial features (see for example here, here, and here).

These features however could also have nothing to do with water ice.

Bezos sells another $3 billion of Amazon shares

8:54 am

Jeff Bezos continues to accelerate his sale of his Amazon stock, selling another $3 billion this week.

In August, Bezos offloaded more than $3.1 billion of Amazon shares, after selling more than $4.1 billion worth of shares in February. The sales this week bring his total cash out in 2020 to more than $10.2 billion so far, which is a notable jump from 2019, when Bezos sold $2.8 billion worth of shares.

While Bezos had originally said these sales were for financing his space company, Blue Origin, it now appears that the bulk of this new money is aimed at funding environmental political organizations such as the Environmental Defense Fund, the Natural Resources Defense Council and the World Wildlife Fund.

Overview of China’s lunar sample return mission

8:29 am

Chang'e-5 landing site on Moon

Link here. The Chinese mission, the first to bring back lunar samples since the 1970s, is now set for launch on November 24, 2020.

Chang’e-5 includes a lander, ascender, orbiter and returner. After the spacecraft enters the Moon’s orbit, the lander-and-ascender pair will split off and descend close to Mons Rümker, a 1,300-metre-high volcanic complex in the northern region of Oceanus Procellarum — the vast, dark lava plains visible from Earth. Once the craft has touched down, it will drill up to 2 metres into the ground and extend a robotic arm to scoop up about 2 kilograms of surface material. The material will be stored in the ascender for lift-off.

The descent and ascent will take place over one lunar day, which is equivalent to around 14 Earth days, to avoid the extreme overnight temperatures that could damage electronics, says Clive Neal, a geoscientist at the University of Notre Dame in Indiana.

…Once the ascender is back in lunar orbit, the samples will be transferred to the returner. This in-flight rendezvous will be complex and “a good rehearsal for future human exploration”, says James Carpenter, a research coordinator for human and robotic exploration at the European Space Agency in Noordwijk, the Netherlands. China plans to send people to the Moon from around 2030.

The Chang’e-5 spacecraft will then journey back to Earth, with the lander parachuting toward Siziwang Banner in Inner Mongolia, northern China, probably sometime in early December.

The location, as shown in the image above, is in the northern mid-latitudes of the Moon’s nearside, and is a place where some relatively recent volcanic activity might have occurred, though still in the far past.

Why Martian mountains are different than on Earth

3:08 pm

A mountain peak on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on August 12, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what to any Earthling’s eye appears to be a somewhat ordinary flat-topped mountain peak with two major flanking ridgelines descending downward to the north and the south, and two minor ridgelines descending to the northwest and southwest.

This peak and its landscape would surely be quite a spectacularly place to visit, should humans ever settle Mars and begin doing sightseeing hikes across its more interesting terrain. I can definitely imagine hiking trails coming up the two minor ridges, with a crest trail traversing the main north-south ridge across the peak.

This is not however a mountain on Earth. It is on Mars, which makes its formation and evolution over time fundamentally different than anything we find on Earth, despite its familiar look.

First, what formed it? Unlike most of Earth’s major mountain chains, the mountains of Mars were not formed by the collision of tectonic plates, squeezing the crust upward. Mars does not have plate tectonics. Most of its mountains formed either from the rise of volcanoes at single hot spots, or from the wearing away of the surrounding terrain to leave behind a peak or mesa.

First fast radio burst detected in Milky Way

10:57 am

Astronomers using both space- and ground-based telescopes have detected for the first time a fast radio burst occurring inside the Milky Way, finding that it came from a magnetar, a pulsar with an extremely powerful magnetic field.

The radio component was discovered by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a radio telescope located at Dominion Radio Astrophysical Observatory in British Columbia and led by McGill University in Montreal, the University of British Columbia, and the University of Toronto.

A NASA-funded project called Survey for Transient Astronomical Radio Emission 2 (STARE2) also detected the radio burst seen by CHIME. Consisting of a trio of detectors in California and Utah and operated by Caltech and NASA’s Jet Propulsion Laboratory in Southern California, STARE 2 is led by Bochenek, Shri Kulkarni at Caltech, and Konstantin Belov at JPL. They determined the burst’s energy was comparable to FRBs.

By the time these bursts occurred, astronomers had already been monitoring their source for more than half a day.

Late on April 27, NASA’s Neil Gehrels Swift Observatory spotted a new round of activity from a magnetar called SGR 1935+2154 (SGR 1935 for short) located in the constellation Vulpecula. It was the object’s most prolific flare-up yet – a storm of rapid-fire X-ray bursts, each lasting less than a second. The storm, which raged for hours, was picked up at various times by Swift, NASA’s Fermi Gamma-ray Space Telescope, and NASA’s Neutron star Interior Composition Explorer (NICER), an X-ray telescope mounted on the International Space Station.

Later observations detected X-rays from the same source. While this does not prove that all fast radio bursts come from magnetars, it does prove that at least some do.

New owners for Vector to revive company

8:30 am

Capitalism in space: The new owners for bankrupt smallsat rocket company Vector have announced that they plan to revive the company.

In their announcement they confirmed that the key problem that killed the original company were engineering issues with its chosen engine design.

One thing they did wrong was the technology the used for their engines. “They had some Achilles’ heels associated with their technical approach. They were trying to use a propellant combination that was untested in the industry,” said Chris Barker, who serves as Vector’s chief rocket scientist. “They were struggling with trying to get performance that they knew they needed for a small launcher to be successful, and ultimately their test program was unsuccessful.”

Vector had been developing engines that used propylene and liquid oxygen propellants. The new Vector plans to instead use engines powered by a more conventional combination of liquid oxygen and refined kerosene, or RP-1, propellants. Barker has been developing such engines since the 1990s for companies such as Space America and Earth to Sky.

The new owners also stated that initially they plan to target the suborbital business field. Their main focus right now is redesigning the Vector-R rocket in conjunction with their engines.

Russians aim for Dec for fixing ISS leak permanently

8:23 am

The Russians announced yesterday that they plan the full and permanent repair of the small inch-long crack leaking air on ISS to occur in December, after required material is shipped to the station.

According to the official, the crack was the width of a hair and located in a hard-to-reach spot of Zvezda’s shell.

Solovyov did not specify the spacecraft that will deliver the sealing materials to the ISS, but the only one scheduled to fly in December is Cargo Dragon, a reusable freight spaceship of US private company SpaceX. The soonest flight of a Russian cargo spacecraft — Progress MS-16 — has been postponed until December 2021.

They also plan a spacewalk in the next two weeks to inspect the exterior of the Zvezda module where the crack is located.

I have yet to see an image of the crack itself. Why none has been made easily available is somewhat puzzling.

And now we wait

The American flag

Trying to predict the outcome of today’s election in today’s world of shallow emotions and partisan bickering is beyond impossible. The pollsters, generally favoring the Democrats, have for months slanted their results to favor Joe Biden. The conservative press, desperate to grasp at any straw, has in turn focused on the early voting numbers, broken down by party, to claim that Trump is leading.

I really don’t know which is right, at this moment. Moreover, there is a lot of evidence that we will not even have a result by the end of tonight.

However, I still would like to make some predictions, because there are some things we know are very likely to happen, regardless of who wins the election.

In Europe, the use of masks leads to more COVID-19 cases

9:28 am

It appears that the three European countries with the strictest mask mandates and the highest percentage of usage are also the three European countries experiencing the highest surge of COVID-19 cases, signaling once again that masks not only do not protect anyone from the virus, they could actually be contributing to its spread.

The Biden campaign and the Democrats are cynically cashing in on these pandemic fears. “We’re in a circumstance where the president thus far and still has no plan, no comprehensive plan,” Biden ranted at the debate. “What I would do is make sure we have everyone encouraged to wear a mask all the time.”

France, Italy, and Spain tried that. It didn’t work.

The European countries most obsessed with masks are doing the worst. Nearly universal mask wearing in those countries has done little to prevent a surge. Democrats have a weakness for wanting to be like the Europeans. But the only thing the Biden mask mandate would do is turn us into France. The French wore masks through the summer heat only to have three times the cases per capita and per day as the Americans who never adopted a mask mandate.

The author outlines the numbers. In France 78% of the population wear masks. In Italy the number is 81%. And in Spain it is as high as 86%. Yet all three have had the biggest recent surges in new cases since the mask mandates were imposed. Meanwhile countries where fewer than a third or less of the population where masks — Sweden, Norway, and the UK — the number of cases is far less, and for Sweden there has been no surge in cases at all..

While the author outlines the failure of these mask mandates to stop the virus’ spread, he does not note one component that might be contributing to the surges in these mask-obsessed countries. Masks if misused and worn when they are not sanitary, as is common when large numbers of people are required to wear them all the time, become pathogen bombs. Instead of blocking the virus (an ability that remains quite unproven), they likely become carriers of the virus, at the very place people breath.

But don’t worry. Though you might be increasing the chances of getting sick, you will “feel-good” about yourself when you put on that mask. It is a talisman that proves your wonderful virtue to everyone else, especially those evil people who have looked at the data and have decided to forego this pathogen spreader.

NASA officially expresses concerns about proposed private communications constellation

8:55 am

For what appears to be an unprecedented action, NASA has officially expressed opposition to a proposed private satellite constellation by the company AST & Science.

NASA’s position was released in a comment to the FCC, where the company has requested a communications license to operate its satellites.

At issue are plans put forth by AST & Science, which intends to build a constellation of more than 240 large satellites, essentially deploying “cell towers” in space to provide 4G and possibly 5G broadband connection directly to cell phones on Earth. The company, based in Midland, Texas, calls its constellation “SpaceMobile” and has raised an estimated $120 million.

The space agency felt compelled to comment on AST’s proposal for several reasons. Most notably, the proposed altitude for the SpaceMobile constellation lies near the “A-Train,” a group of 10 Earth-science monitoring satellites operated by NASA and the US Geological Survey, as well as partners in France and Japan. “Historical experience with the A-Train constellation has shown that this particular region of space tends to produce a large number of conjunctions between space objects,” the NASA letter states.

The satellites are also very large. In order to provide service, AST plans to build spacecraft with large phased array antennae—900 square meters. According to NASA, in planning for potential conjunctions with other satellites and debris in this orbit, this would require proscribing a “hard-body radius” of 30 meters, or as much as 10 times larger than other satellites.

Maneuvering around the proposed SpaceMobile constellation would be extraordinarily taxing, NASA said. “For the completed constellation of 243 satellites, one can expect 1,500 mitigation actions per year and perhaps 15,000 planning activities,” the space agency stated. “This would equate to four maneuvers and 40 active planning activities on any given day.”

The company has said it is willing to work with NASA to ease its concerns. For NASA to take this particular step however is most strange, especially considering the size of this constellation, 240 satellites. This number is tiny compared to the multi-thousands being proposed by SpaceX, Amazon, and OneWeb. Their large size footprint certainly could be a factor, but it does seem puzzling for the space agency to pick out this particular constellation for opposition, and none of the others.

Signal to Voyager-2 confirms upgrade of NASA’s Deep Space Network

8:42 am

After months of downtime in order to install a major and very badly needed upgrade to NASA’s Deep Space Network (DSN) (the worldwide array of radio dishes used to communicate with planetary probes throughout the solar system) a test command to Voyager-2 beyond the orbit of Pluto was sent, received, and executed successfully this week, proving the upgrade is working.

The call to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43, the only dish in the world that can send commands to Voyager 2. Located in Canberra, Australia, it is part of NASA’s Deep Space Network (DSN), a collection of radio antennas around the world used primarily to communicate with spacecraft operating beyond the Moon. Since the dish went offline, mission operators have been able to receive health updates and science data from Voyager 2, but they haven’t been able to send commands to the far-flung probe, which has traveled billions of miles from Earth since its 1977 launch.

Among the upgrades to DSS43, as the dish is known, are two new radio transmitters. One of them, which is used to talk with Voyager 2, hasn’t been replaced in over 47 years. Engineers have also upgraded heating and cooling equipment, power supply equipment, and other electronics needed to run the new transmitters.

The successful call to Voyager 2 is just one indication that the dish will be back online in February 2021.

The upgrade has been overdue for years, and is essential to provide sufficient communications capability for the future interplanetary mission presently planned.

Layered mesa on Mars

Layered mesa on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on June 24, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a distinctive mesa in a mountainous region in the cratered highlands of Mars, just north of Hellas Basin, the deepest basin on the red planet.

The mesa’s most distinctive feature are its terraced layers, a feature that MRO has found in numerous other places surrounding and inside Hellas Basin (see for example the cool images here, here, here, here, here, and here.)

On Earth the assumption would be that these terraced layers imply different sedimentary layers that erode at different rates, as best illustrated by the Grand Canyon in Arizona. On Mars that assumption is not unreasonable, but unlike Earth, those layers could not have been formed in connection with large ocean bodies creating seafloor layers from the deposit of sealife over centuries. Some other geological process over time formed them, with volcanism, either from volcanoes or impact, being the most likely.

Sunspot update: An active October heralds the likely end of solar minimum

12:32 pm

With the start of a new month it is once again time to publish another sunspot update. NOAA yesterday updated its monthly graph for tracking the Sun’s monthly sunspot activity. As I have done now every month since this website started in 2011, it is posted below, with additional annotations by me to show the past solar cycle predictions.

Unlike September, which saw almost no sunspots, October was a very active month, with the amount of sunspots far exceeding prediction. Furthermore, every sunspot during the month had a polarity assigning it to the new solar cycle, not the last.

Vote for Trump, but even more, vote Republican across the board

11:39 am

Trump

I’ve said it before but I will say it again. Donald Trump is the right candidate for president, and everyone who hasn’t yet voted should vote for him tomorrow, both because he kept his promises and has actually done a decent job as president.

However, it is even more important to vote for Republicans across the board. If Trump is re-elected but the voters do not give him strong majorities in both houses of Congress, his ability to do what the voters want will be seriously circumscribed. And if the Democrats win control of both houses of Congress, expect that their first order of business will be to impeach Trump and then try to remove him from office. The goal will be to quickly nullify your vote for Trump, by the party of segregation, slavery, riots, looting, and stolen elections.

And on the local city and state level things are quite simple. » Read more

SpaceX to live stream 50,000 foot hop of Starship

9:20 am

Capitalism in space: Elon Musk yesterday announced that SpaceX will publicly live stream the 50,000-foot hop of Starship prototype #8, expected sometime in the next two weeks. His tweet:

Sure, although it might be quite a short livestream! Lot can go wrong, but we’ll provide video, warts & all. You will see every frame that we do.

Up until now the public has had to depend on the independent live streams being put out by local residents still living in Boca Chica, Texas, which did not know SpaceX’s exact schedule. When SpaceX does it they will likely provide more specific launch times. They will also probably provide detailed accurate commentary.

Also, this update on the status of Starship development notes that the primary goal of that hop is testing the ability of the ship’s fins and systems to control the ship’s initial descent on its return to Earth, flying on its side like the Space Shuttle. If they have problems getting the ship upright for a vertical landing and it ends up in the ocean that will not surprise them. A successful vertical landing would be icing on the cake.

Another movie of OSIRIS-REx’s sample-grab-and-go at Bennu

10:08 am

The OSIRIS-REx science team has released another movie showing the sample-grab-and-go at Bennu, this time from a different camera.

The movie, made up of 189 images taken over three hours by the spacecraft’s navigation camera NavCam-2, can be seen at the link.

In the middle of the sequence, the spacecraft slews, or rotates, so that NavCam 2 looks away from Bennu, toward space. OSIRIS-REx then performs a final slew to point the camera (and the sampling arm) toward the surface again.

As the spacecraft nears site Nightingale, the sampling arm’s shadow comes into view in the lower part of the frame. Shortly after, the sampling head impacts site Nightingale (just outside the camera’s field of view to the upper right) and fires a nitrogen gas bottle, which mobilizes a substantial amount of the sample site’s material. Several seconds later, the spacecraft performs a back-away burn and the sampling arm’s shadow is visible against the disturbed surface material.

The team continues to investigate what caused the extremely dark areas visible in the upper and middle parts of the frame. The upper area could be the edge of the depression created by the sampling arm, a strong shadow cast by material lofted from the surface, or some combination of the two. Similarly, the middle dark region that first appears in the lower left of the image could be a depression caused by one of the spacecraft thrusters as it fired, a shadow caused by lofted material, or a combination of both.

It strikes me that getting post impact images of Nightingale is essential, if at all possible.

Climate scientists are science’s biggest frequent flyers

9:49 am

From the people who want to shut down all fossil fuel technology: A newly published survey of 1,400 scientists from 59 countries has found that climate scientists fly more than researchers in any other field.

Climate experts — who accounted for about 17% of respondents — take five flights per year on average, the study found, whereas researchers who specialize in other fields took four. Climate scientists also fly more often for work than their peers, but take fewer international flights for personal reasons. Air travel becomes more frequent with job seniority across all disciplines, with climate-change professors flying on average nine times per year, and those in non-climate disciplines flying eight times.

Although the difference isn’t enormous, it adds up to a “colossal amount of flying”, says Lorraine Whitmarsh, an environmental psychologist at the University of Bath, UK, who led the study. “These figures are really quite stark, I think, and should be a wake-up call for all of science.”

The survey took place prior to the Wuhan panic, and thus does not tell us about the new fear-driven flying patterns of scientists.

That this story comes from the journal Nature,. which in recent years has become increasing controlled by the leftist propaganda machine, suggests the data is quite convincing. Nature wouldn’t allow any publication of any paper that throws a bad light on global warming or its researchers, unless the data was overwhelming and impossible to ignore.

It also tells us that climate scientists themselves don’t really believe their own doomsday predictions about global warming. Before the Wuhan panic they would routinely run numerous international conferences, often in wonderful warm-weather vacation spots in the midst of winter, and would flock there in the thousands to enjoy that warm weather even as they repeatedly called for government restrictions on everyone else. The article quotes one scientist, who tries to justify this travel:

International conferences might also have an influence, says Kim Cobb, a climate scientist at the Georgia Institute of Technology in Atlanta. Meetings to coordinate global mitigation efforts — such as of the Intergovernmental Panel on Climate Change — involve hundreds of researchers from different countries. “You need to have a frequent series of meetings to keep up with the data, to advance our findings, to make sure that they are disseminated across the community,” says Cobb. [emphasis mine]

I highlight her quote because her reasons for attending such conferences are unadulterated garbage. While it is important to personally get together periodically with other scientists in the field to exchange results (something that is unfortunately no longer happening because of fear of COVID-19), you don’t need to do this “frequently” in today’s intenet society. Nor do you need to do it to “keep up with the data” or to distribute it to everyone else. If anything, such conferences are very inefficient for achieving these goals. The internet does it far better.

No, the purpose of many of these very big climate conferences had nothing to do with science. I’ve attended a few, and noticed how little real science was discussed. Instead, these conferences were political gatherings, aimed at organizing political action and regulation, as determined by these high-flying climate politicos. And they were always in nice warm weather locations, in winter.

To sum up: Until the climate field acts like it believes its own pontifications about the evils of fossil fuels, no one else should.

New data: young red dwarf stars are not nice stars for life

12:50 pm

New data from both the Chandra X-ray Observatory and the Hubble Space Telescope has reinforced earlier data that suggested the strong flares emitted by young red dwarf stars make them inhospitable to the development of life on any planet in the habitable zone.

A new study using NASA’s Chandra X-ray Observatory and Hubble Space Telescope examined the red dwarf called Barnard’s Star, which is about 10 billion years old, more than twice the current age of the Sun. Red dwarf stars are much cooler and less massive than the Sun, and are expected to live much longer lives because they do not burn through their fuel as fast. Barnard’s Star is one of the closest stars to Earth at a distance of only 6 light-years.

Young red dwarfs, with ages less than a few billion years, are known as strong sources of high-energy radiation, including blasts of ultraviolet light and X-rays. However, scientists know less about how much damaging radiation red dwarfs give off later in their lifetimes.

The new observations concluded that about 25% of the time, Barnard’s Star unleashes scorching flares, which may damage the atmospheres of planets closely orbiting it. While its only known planet does not have habitable temperatures, this study adds to evidence that red dwarfs may present serious challenges for life on their planets.

It is very important to remember that this data makes difficult the formation of life, as we know it. Since we know so little about such processes, as well as the formation processes of solar systems, it is too early to say whether no life can ever form around such stars.

Scientists confirm another 44 black hole mergers detected by gravitational waves

12:16 pm

Scientists have now confirmed that since the first detection of a gravitational wave five years ago they have detected another 44 black hole mergers in the same manner.

A global network of scientists has completed the first major analysis of gravitational wave data, providing exciting insights into some of the most exotic objects in the Universe. “We are announcing the discovery of 44 confirmed black hole mergers, which is a more than a four-fold increase in the number of previously known gravitational-wave signals,” says Shanika Galaudage from Australia’s Monash University, who was part of the research team.

…Their results are described in a trio of papers on the pre-print server arXiv. The first paper describes 39 new detections from the first half of the observing run, primarily of binary black hole systems. This brings the total number of gravitational wave events detected to 47, of which 44 are confidently double black holes, two are confidently double neutron stars, and one is still uncertain.

They think they are detecting more black hole mergers because they are heavier and thus emit bigger and more easily detected waves. They are also finding that the black hole mergers fall into two classes, two holes spinning in the same direction and two holes spinning in opposite or randomly different directions. The former formed together as a binary star system. The latter formed independently and somehow ended up linked up and merging.

U.S. court orders India’s s space agency ISRO to pay $1.2 billion

11:21 am

A U.S. court has ordered Antrix, the commercial arm of India’s space agency ISRO, to pay $1.2 billion to Devas, a private company with operations in both India and the United States, for a contract they canceled arbitrarily in 2011.

This is a very complicated story going back many years. ISRO’s Antrix and Devas had agreements beginning in 2005 to work together to develop commercial satellites, with Antrix building the satellites and Devas commercializing bandwidth. In 2011 the India government cancelled the contracts unilaterally.

On February 25, 2011, Antrix issued a termination notice to Devas, which among other things stated that the policy decision was of the central government, acting in its sovereign capacity is the event of force majeure, which was an occurrence on February 23, 2011, PTI report said. “The scope and duration of the said decision cannot be anticipated. It is likely to be indefinite. It is not possible for Antrix to take any effective step to resume the obligations under the agreement,” Antrix was quoted as saying.

One of the reasons for the cancellation were accusations that payoffs were occurring between officials at both Antrix and Devas to make the deal happen.

Devas has been fighting in numerous courts for years to get compensation for that cancellation.

ISRO can probably ignore this U.S. court decision, except that if it does it will make it very difficult, if not impossible, for ISRO to do any work in partnership with the U.S., such as in the Artemis program. As soon as they try to do so, Devas will slap a lien on that operation, demanding payment.

Russian astronaut: Crack on ISS could be from “external impact”

10:48 am

Russian astronaut, Sergei Ryzhikov, today noted that to him the 1-inch crack causing the leak on ISS appeared to have been caused by an “external impact.”

Speaking with Flight Director of the Russian segment of the ISS Vladimir Solovyov, Russian cosmonaut Sergei Ryzhikov said: “If you take a closer look at the picture, there are changes of color in the middle of the crack.”

“We suspect an external impact,” Ryzhikov said adding that the place of the suspected impact should be examined during the crew’s next spacewalk, which is scheduled for November 18.

This conclusion is different than that expressed yesterday by another Russian astronaut, who suggested the crack was from age and wear and tear of the twenty-year-old Zvezda module.

Either way, an inspection of the exterior point of the crack is essential in order to permanently seal it, and that inspection will tell us one way or the other the cause of the crack.

War between two Spanish space balloon companies

10:35 am

Capitalism in space: A legal battle is developing between two different Spanish high altitude space balloon companies, one that came first, and a second that is being backed by a venture capitalist who had previously worked at the first.

Jose Mariano Lopez Urdiales, an MIT-trained aeronautics engineer who founded Zero 2 Infinity 11 years ago, says Kemel Kharbachi, the now CEO of EOS X Space, worked closely with the company to raise a €1m investment for Zero 2 Infinity. But the funding deal never happened.

Instead, Kharbachi, whose previous experience has focused on tourism and catering, has emerged to build his own rival space balloon business.

It does appear, from the details outlined in the article, that Kharbachi essentially stole the concept and designs from Zero 2 Infinity in order to form his own company.

As these Spanish companies fight it out, a third company in America, Space Perspectives, hopes to begin flying tourists on its stratospheric balloon, dubbed Neptune, by ’24.
