2016 documents now prove Obama and his top intelligence officials conspired to create the Russian collusion hoax

1:15 pm

Evidence Obama conspired to overthrow Trump
Click for full graphic.

Treason: Documents now released from 2016, just after Trump’s election victory, now prove without doubt that Obama and his top intelligence officials conspired to create Russian collusion hoax, despite having assessments by their intelligence agencies declaring Russian actions did not include Trump and had no impact at all on the 2016 election.

That assessment is nicely summarized by the screen capture to the right.

We assess that Russian and criminal actors did not impact recent US election results by conducting malicious cyber activities against election infrastructure.

After getting that negative assessment, Obama immediately called a meeting to rewrite the conclusions, in order to create a fake political issue aimed directly at destroying Trump’s presidency.

Update on eye research at ISS

10:03 am

Link here. The NASA update provides a nice overview of the research, beginning with this overview:

When astronauts began spending six months and more aboard the International Space Station, they started to notice changes in their vision. For example, many found that, as their mission progressed, they needed stronger reading glasses. Researchers studying this phenomenon identified swelling in the optic disc, which is where the optic nerve enters the retina, and flattening of the eye shape. These symptoms became known as Space-Associated Neuro-Ocular Syndrome (SANS).

The research suspects the changes are due to the fluid shifts in the body that take place due to weightlessness, with blood shifting from the legs to the head. Various projects have studied a number of solutions, including wearing leg cuffs, administering vitamin B, and possibly using centrifuge-created artificial gravity to mitigate the condition. The problem has also generated new work in developing better equipment for to studying the eye, including improved imaging and techniques for measuring the eye’s stiffness.

Founder of Saxavord spaceport diagnosed with terminal cancer

9:51 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

Frank Strange, the founder and CEO of the Saxavord spaceport in the Shetland Islands, yesterday revealed that he has been diagnosed with terminal cancer and is given about six months to two years to live.

He said he was hopeful to be present for what could be the first orbital rocket launch from UK soil now expected to happen in November of this year.

Speaking to Shetland News on Thursday, the 67-year-old said the future of the spaceport was in good hands with a highly capable management team and very supportive investors.

Reflecting on his health, Strang said he had been struggling eating over past months. An endoscopy a few weeks ago discovered a tumour in his oesophagus (gullet) which was found to be cancerous and had also spread to the lungs. “I am going to step back but not down,” he said. “If I step down that would probably kill me before the cancer does.

“The spaceport has been my life; it has come at a high personal cost over the years.”

It would truly be a tragedy if this man dies before the first launch at Saxavord occurs. The German rocket startup Rocket Factory Augsburg had hoped to do a launch there last year, but an explosion during a prelaunch static fire test made that impossible. It hopes to try again in December, assuming the United Kingdom’s odious red tape does not get in the way.

Polish rocket startup signs second spaceport deal this week

9:38 am

Santa Maria spaceport

The Polish rocket startup SpaceForest today announced that it has signed a deal to launch its Perun suborbital rocket with the Atlantic Spaceport Consortium that is developing a spaceport on the island of Santa Maria in the Atlantic.

The launch planned for early 2026 will allow for comprehensive testing of launch procedures and confirmation of the capabilities and compliance of the Polish platform for conducting space experiments and research outside Poland, fully aligned with international standards. The mission will also serve as an opportunity to verify the operation of the PERUN suborbital flight system under nominal mission parameters.

This is the second spaceport launch contract SpaceForest has signed this week, the first being with the Eurospaceport launch platform to be located in the North Sea. According to the press releases, the Santa Maria launch will likely occur first. SpaceForest has also signed an agreement to launch its rocket from Norway’s Andoya spaceport. All three contracts suggest the company is marketing its suborbital rocket to new proposed European spaceports as a way to demonstrate the spaceport’s viability as a launch location.

The Santa Maria spaceport was first proposed by the Atlantic Spaceport Consortium in August 2024, and has already done two suborbital test launches, both using what appeared to be large model rockets. This contract gives it is first customer.

Musk: 10th Starship/Superheavy launch in “about three weeks”

12:31 pm

According to a very short tweet Elon Musk posted on July 15, 2025, SpaceX will attempt the 10th orbital test flight of Starship/Superheavy in “about three weeks.”

Musk however provided little information. This is the full text of his tweet:

Launching again in ~3 weeks

The lack of information raises more questions than it answers. For example, how is SpaceX replacing the destroyed Starship that blew up during a static fire test in June on its Massey test stand at Boca Chica? I assume it is using another prototype already in the assembly line, but will it be a version 2 prototype that the company has flown on the past three flights that failed each time after stage separation from Superheavy? Or has SpaceX dumped the prototypes of version 2 and shifted directly to version 3 because of those failures?

How is it going to do its Starship prelaunch static fire tests? Has it gotten its Massey test stand repaired that quickly, or has it found other options? Earlier reports suggested fixing the stand would take much longer. Furthermore, there was the question of fixing it for version 2 or version 3, which require different configurations. Fixing it for version 2 suggested this would delay bringing version 3 on line.

This tweet raises more questions than it answers. However, if Musk is even close to correct than many of these questions will be answered in only a week or two, since that is when prelaunch static fire test must begin.

Astronomers detect first evidence of gas condensing to molecular solids in baby solar system

11:39 am

Baby star with jets of new material
Click for original image.

Using a combination of ground- and space-based telescopes, astronomers have detected the first evidence of the gas and dust surrounding a young star condensing to molecular solids, thus beginning the initial stages of planet formation.

This newborn planetary system is emerging around HOPS-315, a ‘proto’ or baby star that sits some 1300 light-years away from us and is an analogue of the nascent Sun. Around such baby stars, astronomers often see discs of gas and dust known as ‘protoplanetary discs’, which are the birthplaces of new planets. … Their results show that SiO [silicon monoxide] is present around the baby star in its gaseous state, as well as within these crystalline minerals, suggesting it is only just beginning to solidify. “This process has never been seen before in a protoplanetary disc — or anywhere outside our Solar System,” says co-author Edwin Bergin, a professor at the University of Michigan, USA.

…With these data, the team determined that the chemical signals were coming from a small region of the disc around the star equivalent to the orbit of the asteroid belt around the Sun.

The false-color picture to the right, cropped, reduced, and sharpened to post here, was taken by the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile. It shows jets blowing out from the central baby star. Orange indicates carbon monoxide, while blue is the silicon monoxide. Initially the astronomers detected these molecules using spectroscopy from the Webb Space Telescope. This ALMA image was then used to identify where these molecules were located in the system.

Proposed North Sea offshore launch platform gets ESA okay

10:38 am

Launch platforms proposed for North Sea
Launch platforms proposed for North Sea

The proposed North Sea offshore launch platform of the startup Eurospaceport has now signed an agreement with the European Space Agency to support a test launch of a suborbital test rocket by Polish rocket startup SpaceForest.

The map to the right shows approximately where Eurospaceport’s launch platform will be located for this launch. The map also shows the locations of the two proposed spaceports in the United Kingdom, as well as a second German-based launch platform, Offshore Spaceport Alliance, based out of Bremen.

The SpaceForest launch is targeting a 2026 launch, with the ESA contract covering some of the expenses. As it will be suborbital, the rocket will likely not cross over any nearby habitable land.

The Offshore Spaceport was first proposed in 2020, and has received financial support from the German government, and announced earlier this year that it would be ready to host launches by September 2025. As of yet no launches have been scheduled.

Both of these launch platforms will need to travel farther to the west in the North Sea to provide any orbital rockets a path north that will not fly over other nations. Even so, launches for both will likely be limited to polar orbits, making their value less appealing to rocket companies.

At the same time, their proximity to Europe and the ability of the launch platforms to dock in Europe gives them other advantages that will be of interest to the German rocket startups.

South Korea to push for a lunar base and Mars missions by 2045

9:58 am

South Korea’s new space agency today announced a long term space exploration road map that hopes to have the nation establish by 2045 a small base on the Moon as well as a Mars orbiter and lander.

The Korea Aerospace Administration (KASA) categorizes the exploration areas into Earth, the Moon, the heliosphere, and deep space, dividing them into five major programs: low orbit and microgravity exploration, lunar exploration, solar and space science exploration, planetary system exploration, and astrophysical exploration. The roadmap presents scientific missions for each program and engineering tasks to realize them.

When South Korea established this space agency in 2024, its chief emphasized the need to encourage private enterprise. I however had doubts, noting:

If KASA maintains this approach, then South Korea’s future as a space power is bright. If instead KASA moves to control all space development, including the design and ownership of its rockets and spacecraft, then that program will be stifled, as America’s was by NASA for forty years after the 1960s space race.

In January 2025 that space agency announced policies that it said would encourage the private sector, but in reviewing the language of those policies I concluded it sounded more like a power-play by that agency to run everything.

KASA’s new road map today unfortunately confirms that analysis. Over the next two decades South Korea will have a government-controlled “space program,” not a competitive space industry.

New Space Force policy will encourage a robust private industry to build the capabilities it needs

9:39 am

Capitalism in space: The U.S. Space Force (USSF) today released what it calls an “annex,” outlining its “Principles for Space Access Resourcing Decisions,” that will act as an over-arching guidance to its general space policy. The nine principles listed are expressly focused on encouraging redundancy in launch and satellite military capabilities by using the robust private and competitive aerospace industry that now exists.

The annex details how the service will consider and prioritize commercial space sector requests for government resources, as well as government investment decisions. The annex features nine principles, rooted in law, that will guide the Assured Access to Space Enterprise’s decision-making on a variety of resourcing decisions including acquisition strategies, investment priorities and property allocation. … “These principles reflect our understanding that a strong commercial space industry is a force multiplier for the U.S. Space Force. We are committed to working alongside our industry and allied partners to ensure safe, reliable and resilient access to space for decades to come,” [said Deputy Chief of Space Operations for Strategy, Plans, Programs and Requirements Lt. Gen. Shawn N. Bratton.]

The annex signals an acknowledgment of the evolution of the space access landscape from the 1950s, in which the government was the primary customer, to today where commercial space activities account for the preponderance of launch manifest activities.

You can read the full “annex” here [pdf]. The principles clearly emphasize the need to use the private sector for the military’s needs. It also underlines the Space Force’s responsibility to serve the needs of this growing private sector by making its launch ranges as available as possible to that industry.

The principles however also recognize that strain caused that increased use, and adds this last principle as a caveat:

Launch rates at Cape Canaveral Space Force Station and Vandenberg Space Force Base have increased to the point where commercial and hybrid launches comprise the vast majority of operations. The demand for operational support and infrastructure sustainment and modernization exceeds USSF resources. Therefore, the USSF transparently engages with stakeholders to arrange equitable cost-sharing of multi-use resources and balanced input on public/private infrastructure investment.

It makes excellent sense for the military to re-negotiate its fees with the launch companies that use its facilities to cover costs. In fact, this is a much better way to cover these costs than the launch taxes proposed by Senator Ted Cruz’s budget bill in June. Cruz’s proposal is a legal tax that allows no room for negotiation. The Space Force’s policy will allow it flexibility to negotiate fees as needed and with much greater efficiency and speed.

Sadly, expect Cruz’s taxes to win out, as this kind of heavy-handed overuse of government power has been the default for decades.

Satellite companies SES and Intelsat complete their merger

9:07 am

The Luxembourg-based satellite company SES has now completed its acquisition of the European-based satellite company Intelsat, giving the combined company 120 active satellites in a variety of low and high Earth orbits.

With a world-class network including approximately 90 geostationary (GEO), nearly 30 medium earth orbit (MEO) satellites, strategic access to low earth orbit (LEO) satellites, and an extensive ground network, SES can now deliver connectivity solutions utilising complementary spectrum bands including C-, Ku-, Ka-, Military Ka-, X-band, and Ultra High Frequency. The expanded capabilities of the combined company will enable it to deliver premium-quality services and tailored solutions to its customers. The company’s assets and networks, once fully integrated, will put SES in a strong competitive position to better serve the evolving needs of its customers including governments, aviation, maritime, and media across the globe.

Both companies are long established, with Intelsat initially founded in the mid-1960s as a consortium of 23 nations aimed at launching the first geosynchronous communications satellites over the Atlantic and Pacific serving most of the Old World and linked to the New.

The merger is an attempt by both companies to compete with the new low-orbit constellations of SpaceX, Amazon, and from China.

Russia: Commercial satellite constellations providing help to the Ukraine are now targets

10:39 pm

Russia this week informed regulators at the International Telecommunications Union (ITU) that it now considers all European and American private satellite constellations “legitimate targets to be destroyed” if they provide any help to the Ukraine.

Russia tells ITU that GPS/Galileo/GNSS nav & commercial broadcast sats helping Ukraine militarily should expect interference. Same for EutelsatGroup, OneWeb, Starlink constellations, which Russia has said are ‘legitimate targets to be destroyed.

There is more at the full article, but that is behind a subscription paywall.

Russia’s announcement here is probably in response to Trump’s more bellicose statements recently about Putin and Russia.

It is hard to predict what will happen, especially when you have a dictator like Putin in power where rational thinking can never be relied on and no laws apply. For example, destroying any orbiting satellites in low Earth orbit will create space junk that will threaten ISS, and a situation NOT beneficial to Russia.

I suspect Russia will begin by trying to jam these constellations. Let us hope it does not go farther than that.

  • Sierra Space wins contract from Mitsubishi to deliver hardware to ISS
    Though the press release does not say, we must assume delivery will be via Sierra’s Tenacity mini-shuttle, which still has not flown and is years behind schedule. That the release does not mention Tenacity however is not a good thing, suggesting Sierra is not sure it will be available for use and will need to find other alternatives.

Poll: A near majority of Americans are now disgusted with the Ivy league

2:16 pm

What many now label the
A better name might be the “Poison Ivy League”

Good news: A new poll taken of 2,000 registered voters in June 2025 has found that the reputation of the Ivy League universities continues to decline, and has now dropped so much that almost half of those polled had no trust at all in these institutions.

A new poll by the Manhattan Institute found that only 15 percent of voters have a great deal of trust in the elite universities, while 46 percent have little to no trust at all.

Most of those polled said they want to see reforms such as the elimination of diversity, equity, and inclusion and race-based admissions and programs. Additionally, 64 percent “support requiring universities to advance truth over ideology by enforcing rigorous academic standards, controlling for academic fraud, requiring preregistration of scientific studies, and basing decisions on merit,” the poll found.

You can read the poll itself here. Though it covers many other major institutions, such as Congress, big business, the Presidency, public colleges and universities, it is this line item shown in the figure below that I think that stands out most starkly.

Mars meteorite sells at auction for $5.3 million

12:46 pm

The largest Mars meteorite found so far on Earth sold yesterday at auction for $5.3 million, a million dollars more than expected.

The 54-pound (25-kilogram) rock named NWA 16788 was discovered in the Sahara Desert in Niger by a meteorite hunter in November 2023, after having been blown off the surface of Mars by a massive asteroid strike and traveling 140 million miles (225 million kilometers) to Earth, according to Sotheby’s. The estimated sale price before the auction was $2 million to $4 million.

The identity of the buyer was not immediately disclosed. The final bid was $4.3 million. Adding various fees and costs, the official bid price was about $5.3 million.

Most Mars’ meteorites found on Earth are scooped up in Antarctica as part of government funded research. Thus, they are not available for sale. This rock was found by a private meteorite hunter, who then owned the rock free and clear and could do with it as he or she liked. It appears the hunting paid off handsomely.

Axiom’s ticket price for India’s astronaut on Ax-4 mission: $59 million

10:38 am

According to reports today in the India press, the price Axiom charged India’s space agency ISRO for training and then flying its astronaut on the just completed Ax-4 two-week mission to ISS was $59 million.

The expenditure by ISRO includes cost of [Shubhanshu] Shukla’s training for the mission as well as that of a seat on SpaceX’s Dragon spacecraft for the 20-day trip that launched Shukla, and three others — Peggy Whitson from the US, Slawosz Uznanski-Wisniewski of Poland and Tibor Kapu of Hungary — to space.

Earlier reports had suggested Axiom was charging $70 million per ticket. If the $59 million is accurate and applies to the charges Poland and Hungary paid, then Axiom’s revenue for the flight was $177 million. From that it would have to pay SpaceX (for the launch and the use of its Grace capsule) and NASA (for the use of ISS). Based on past history, SpaceX likely charged around $70 million for the launch. The cost for using Grace is unknown. NASA’s fees for a two-week visit to ISS were probably around $10 million plus.

My guess, based on this very limited information, is that Axiom made some profit from the flight, ranging from $20 to $50 million.

Scientists: The Sun’s bright corona acts to impede coronal mass ejections

10:23 am

Using data gathered by the Solar and Heliospheric Observatory (SOHO) since its launch in 1995, scientists have determined that when the Sun’s corona (its atmosphere) is bright, it acts to slow and even block the ejection of coronal mass ejections (CMEs), which if they impact the Earth’s magnetic field can have a harmful effect on our modern technology.

Using data from NRL’s Large Angle and Spectrometric Coronagraph Experiment (LASCO) on board the joint European Space Agency (ESA)-NASA Solar and Heliospheric Observatory (SOHO), the NRL team [National Research Laboratory] compiled nearly three decades of observations of the solar corona. They studied the extensive dataset to investigate trends in the brightness of the Sun’s corona and compare them to CME velocities over the same period. Their study found a strong correlation between the two datasets, with bright regions of the solar corona appearing to relate to substantially slower CME velocities and, in some cases, perhaps entirely precluding CMEs.

This data will help solar weather observers better predict the arrival of CMEs, should they erupt from the Sun aimed at Earth. It will also allow them to gauge the risk of CMEs even occurring.

SpaceX planning to use Starship for manufacturing in space

10:00 am

It appears the enthusiastic investment response last week to the potential of using Varda’s re-turnable capsule for manufacturing in space (especially of pharmceuticals) has caught SpaceX’s interest. According to a news report yesterday, SpaceX has now begun developing a program to use Starship for the same purpose, delivering the raw materials in orbit for short or long periods while these products are produced automatically and then returning them for sale on Earth.

Under the plan, internally called Starfall, SpaceX’s Starship rocket would bring products such as pharmaceutical components to space in small, uncrewed capsules, said one of the people, who spoke on condition of anonymity because the matter is confidential.

Starship would then deploy the capsules, which would spend time in orbit before reentering the atmosphere, where they could be recovered back on Earth, the person added.

This description by this anonymous source seems inaccurate however. Why even consider using these small separate capsules when the entire operation can be put inside Starship, which can then bring everything home when ready? Moreover, Starship’s ability to put a lot of mass in a large space up into orbit gives it an great advantage over the smaller capsules being developed by companies like Varda.

Either way, the advantages of weightlessness for producing products for profit are finally being realized, after decades of blockage by government intransigence. Since the Challenger accident in 1986 and Reagan’s order that the shuttle would no longer not be used for commercial purposes, NASA has forbidden production on its spacecraft and ISS of any products for sale afterward.

Now that the cost of launch has dropped significantly (Thank you Elon Musk!), many investors and companies are seeing great potential for manufacturing in space. And those profits will help feed a private space industry, making the government agency of NASA even more irrelevant.

SpaceX completes its first launch for Amazon

11:39 pm

SpaceX tonight successfully launched 24 Kuiper satellites for Amazon’s internet constellation, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its first launch, landing on a drone ship in the Atlantic. This was the third new stage launched in 2025, and follows the company’s recent pattern of launching between one to three new stages per year. The two fairings completed their 27th and 28th flights respectively. As of posting the satellites had not yet been deployed.

This was SpaceX’s first launch for Amazon, out of an initial contract of three launches. The launch was also Amazon’s third Kuiper satellite launch, the previous two by ULA on its Atlas-5 rocket, launching 27 satellites each. While ULA seems poised to begin regular launches for Amazon, having a contract for 46 launches (with completed two), the contracts for Blue Origin’s New Glenn (27 launches, and ArianeGroup’s Ariane-6 (18 launches) are more uncertain. Neither company has achieved any launches on their contracts, and it is not clear when either company, especially Blue Origin, will ever begin regular launches.

This slow launch pace from these companies is a serious problem for Amazon, which is required by its FCC licence to get 1,600 satellites in orbit by July 2026. For this reason, there are rumors that Amazon might switching more launches to SpaceX, as it has the capability of to launch frequently.

We will have to wait and see.

First good image released of interstellar object 3I/Atlas as it plunges through the solar system

3:25 pm

First good image of instellator object 3I/Atlas
Click for original image of 3I/Atlas.

Astronomers using the Gemini North Telescope in Hawaii have obtained the first good image of the interstellar object 3I/Atlas, as it plunges within the orbit of Jupiter on its way through the solar system.

That picture is to the right, cropped to post here and overlaid on top of a map showing the interstellar object’s calculated path through the solar system.

The picture clearly shows this is a comet, with central nucleus surrounded by a cloud of dust and gas. The data also suggests its nucleus has a diameter of about twelve miles. That it resembles a comet also suggests it is a dirty snowball, made up of ice and rocky material mixed together.

Because it will never get closer to the Sun then just inside the orbit of Mars, it is not likely it will ever get bright enough for naked eye observations. At the same time, it is large enough and will be close enough to make possible some excellent observations as it zips by and leaves the solar system sometime in the fall. The previous two identified interstellar objects, Oumuamua and Comet 21/Borisov, were either too small or too far away as they flew past to get this kind of good data.

Another win for a blacklisted professor

2:59 pm

Professor Timothy Jackson
Music historian Timothy Jackson

Fight! Fight! Fight! After the public University of North Texas (UNT) blacklisted and dismissed professor Timothy Jackson in 2020 from his job as editor of the music history journal he founded for daring to express some academic conclusions the faculty and students didn’t like, he sued.

After a five year battle, Jackson and the university have now settled out of court, with the terms of the settlement [pdf] largely a big win for Jackson.

First the background: In 2019 woke music theorist Philip Ewell of Hunter College in New York gave a presentation to the Society of Music Theory where he claimed 20th century music theorist Heinrich Schenker was a “virulent racist” whose “racist views infected his music theoretical arguments.”

Jackson, who had devoted his career studying Schenker and had co-founded at the university the Journal of Schenkerian Studies focused expressly on Schenker’s works, knew this was patently untrue. For example, Schenker was also a Jew who was a victim of German anti-Semitism and lost many relatives in the Holocaust, facts that Ewell somehow did not think important to mention. To counter Ewell’s historical slanders, Jackson decided to dedicate the next issue of the journal to this issue, presenting essays from both sides. He even asked Ewell to write an essay.

Ewell did not respond. In Jackson’s own essay he outlined in detail the historical facts — as he knew them as an expert on this subject — that put the lie to Ewell’s claims. As Jackson noted, “Ewell peddled a ‘conspiracy theory’ that is ‘part and parcel of the much broader current of Black anti-semitism.'”

Instead of celebrating this perfect example of free speech, the university immediately moved to punish Jackson.

The failed MethaneSat climate satellite apparently had problems from launch

10:24 am

According to a detailed New Zealand news report today, the failed MethaneSat climate satellite — funded and operated by the Environmental Defense Fund — apparently had significant problems during its short fifteen month life-span, going into safe mode many times, before failing completely last month.

An earlier report from this same news outlet described more fully the issues — which began in September 2024 only about six months after launch.

The mission’s chief scientist has now said more intense solar activity because of a peak in the sun’s magnetic cycle has been causing MethaneSAT to go into safe mode. The satellite has to be carefully restarted every time.

There has also been a problem with one of the satellite’s three thrusters, which maintain its altitude and steer the spacecraft. MethaneSAT says it can operate fully on two thrusters.

It appears there is a lot of unhappiness in New Zealand for spending $32 million on this project that was designed, built, and operated by an environmental activist organization with little space experience.

What is clear now is that the spacecraft likely got relatively little data during its fifteen month life span.

Webb spots aftermath of collision of two galaxies

10:06 am

colliding galaxies
Click for source.

Using the Webb Space Telescope, astronomers have discovered the collision of two spiral galaxies that appears to have caused a supermassive black hole to collapse in its wake.

The Webb false-color infrared image to the right shows the two galaxies as the red dots, both surrounded by a ring, with the supermassive black hole the bluish spot in between but offset somewhat to the left. Follow-up radio observations suggested that this bluish spot was a supermassive black hole, having a mass of a million suns and sucking up matter from the giant gas cloud that surrounds it.

The team proposes that the black hole formed there via the direct collapse of a gas cloud – a process that may explain some of the incredibly massive black holes Webb has found in the early universe.

This hypothesis however has enormous uncertainties, and requires a lot more observations to confirm. The black hole could simply exist unrelated to the galaxy collision, having come there from elsewhere. Or it could be from a third galaxy in this group that these initial observations have not yet detected.

The image however is quite cool.
