The Euclid science team today released five early science images in connection of the publication of ten papers.

The picture to the right is one of those images, cropped, reduced, and sharpened to post here. From the caption:

In this image Euclid showcases NGC 6744, an archetype of the kind of galaxy currently forming most of the stars in the local Universe. Euclid’s large field-of-view covers the entire galaxy, capturing not only spiral structure on larger scales but also exquisite detail on small spatial scales. This includes feather-like lanes of dust emerging as ‘spurs’ from the spiral arms, shown here with incredible clarity.

Scientists are using this dataset to understand how dust and gas are linked to star formation; map how different star populations are distributed throughout galaxies and where stars are currently forming; and unravel the physics behind the structure of spiral galaxies, something that is still not fully understood after decades of study.

Euclid is a wide-field space telescope that has instruments that observe in both visible and near-infrared wavelengths. Its primary mirror at 1.2 meters is half the width of Hubble’s. More details about these early images and links to the new science results can be found here.

Unlike Hubble, it appears Euclid will not be used as a general observatory, at least initially. Its primary goal is to do a survey of one third of the sky, focusing on extragalactic sources outside the Milky Way. Once this is complete however it is possible the space telescope will be made available for other observations.

The probe Psyche has successfully completed its six-month checkout since its launch in October 2023 and is now using its ion engines to steadily increase its speed as it heads to a 2029 rendezvous with the metal asteroid Psyche.

The orbiter is now more than 190 million miles (300 million kilometers) away and moving at a clip of 23 miles per second (37 kilometers per second), relative to Earth. That’s about 84,000 mph (135,000 kph). Over time, with no atmospheric drag to slow it down, Psyche will accelerate to speeds of up to 124,000 mph (200,000 kph).

The spacecraft will arrive at the metal-rich asteroid Psyche in 2029 and will make observations from orbit for about two years. The data it collects will help scientists better understand the formation of rocky planets with metallic cores, including Earth. Scientists have evidence that the asteroid, which is about 173 miles (280 kilometers) across at its widest point, may be the partial core of a planetesimal, the building block of an early planet.

The graphic to the right shows the path Psyche will take to get to the asteroid.

Two of Voyager-1’s four instruments resume science operations

9:15 am

Engineers have resumed getting science data from two of Voyager-1’s four instruments for the first time since in November 2023, when corrupted computer memory caused the spacecraft to send only incoherent data.

The plasma wave subsystem and magnetometer instrument are now returning usable science data. As part of the effort to restore Voyager 1 to normal operations, the mission is continuing work on the cosmic ray subsystem and low energy charged particle instrument. (Six additional instruments aboard Voyager 1 are either no longer working or were turned off after the probe’s flyby of Saturn.)

Engineers hope to begin getting good data the other two instruments in the next few weeks.

Glacial tributaries draining south on Mars

Glacial tributaries draining south on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 27, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “valley network”, what appears to be several tributaries flowing downhill from the northeast to come together into a larger single flow to the southwest. The elevation drop from the high to the low points in this picture is about 600 feet.

What formed the valleys? This location is at 35 degrees south latitude, so we are almost certainly looking at what appear to be shallow glaciers within those valleys, protected by a thin veneer of dust and debris. It also appears that the stippled surrounding plains might also contain a lot of near-surface ice, also protected by a thin layer of dust and debris. The stippling indicates some sublimation and erosion.

Solar storms are simply no longer a threat

The sunspot cycle as of May 2024

Today’s Chicken Little Report: When NOAA predicted on May 9, 2024 that a powerful solar flare had erupted from the Sun and was aiming a major solar storm directly at the Earth, the scientists at the federal government’s Space Weather Prediction Center could not help underlining the disaster potential, and were ably aided by the mainstream press. This CNN report was typical:

“Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations,” according to the Space Weather Prediction Center. “(The center) has notified the operators of these systems so they can take protective action.”

The center has notified operators in these areas to take action to mitigate the potential for any impacts, which include the possibility of increased and more frequent voltage control problems. Other aspects operators will monitor include a chance of anomalies or impacts to satellite operations and frequent or longer periods of GPS degradation.

And as always, the news report has to end with this warning of doom:

Court rules COVID jab mandate unconstitutional

11:55 am

One more COVID story to start the week: Earlier this month the 10th Circuit of the U.S. Court of Appeals ruled unequivocally that the mandates requiring the jab and limiting who could be exempted that were imposed by the University of Colorado were unconstitutional.

The University of Colorado Anschutz Medical Campus in 2021 required COVID-19 vaccination of all students and employees. It initially offered religious exemptions to anyone who checked a box, but it later stated that administrators would “only recognize religious exemptions based on religious beliefs whose teachings are opposed to all immunizations.”

Officials, for instance, said Christian Scientists would qualify for an exemption but Buddhists would not. They also said exemptions would be granted only to people who never received any vaccinations.

Medical exemptions, on the other hand, were available if a doctor said the prospective recipient’s health or life would be endangered.

College officials would also reject exemptions solely on their own opinion on whether the applicant’s religion was really against vaccinations or not.

The court’s ruling now allows the lawsuit of seventeen students and employees to go forward.

Former head of NIH admits 6-foot social distancing rule had no scientific basis at all

11:12 am

It was all a lie: In the transcript of a closed-door interview of former NIH director Francis Collins that was released on May 16, 2024, Collins admitted under questioning that there was absolutely no science research or justification behind 6-foot social distancing rule that the government imposed during the Wuhan panic.

“We asked Dr. Fauci where the six feet came from and he said it kind of just appeared, is the quote,” the majority counsel on the committee told Dr. Collins, per the transcript. “Do you recall science or evidence that supported the six-feet distance?”

“I do not,” Collins replied.

Counsel then asked, “Is that I do not recall or I do not see any evidence supporting six feet?”

To which Collins replied “I did not see evidence, but I’m not sure I would have been shown evidence at that point.”

“Since then, it has been an awfully large topic. Have you seen any evidence since then supporting six feet?” Counsel replied.

“No,” said Collins.

None of this is a surprise to those who were paying attention. Back in August 2020 I reported how there was no scientific evidence backing up the six-foot social distancing rule, and that in fact it appears it came from a high school research project that was not based on actual data but on a computer simulation comparable to SIM City.

Even now, the CDC continues to recommend the 6-foot spacing rule, though those rules are based on nothing more than the opinion of some petty dictator in the bureaucracy.

During the entire COVID panic I complained repeatedly about the lack of scientific evidence. Every time the CDC or the government would change its rules, I’d ask, “What new research has appeared to justify this change?” Of course, there never was any new research. These petty goons simply made it up as they went along.

A really really big landslide on Mars

1:22 pm

A really really big landslide on Mars
Click for original image.

Sometimes the cool geological features I find in the Mars Reconnaissance Orbiter (MRO) image archive are so large they are difficult to present on this webpage. Today is an example. The picture to the right, cropped, reduced, and sharpened to post here, was taken on March 13, 2024 by the high resolution camera on MRO. It shows the distinct run-out of debris from a landslide that flowed downhill to the north as a single unit of material. Along the way it carved its track in the ground, almost like a ramp.

The full picture however suggested something much more spectacular. In that full image this landslide is merely a small side avalanche to a landslide many times larger. And that high resolution picture only shows what appears to be a small section of that giant slide. Obviously, this required a look at the global mosaic produced by MRO’s context camera to find out how far that avalanche actually extended.

NASA signs new agreement with ESA to partner on Franklin Mars rover

9:41 am

NASA yesterday signed a new agreement with the European Space Agency (ESA) that confirmed its previous commitment to help land ESA’s Franklin rover on Mars.

With this memorandum of understanding, the NASA Launch Services Program will procure a U.S. commercial launch provider for the Rosalind Franklin rover. The agency will also provide heater units and elements of the propulsion system needed to land on Mars.

Previously NASA had committed $30 million to pay for that launch provider, as yet undetermined. It now wants $49 million for the Franklin mission, with the extra money likely to pay for the new additional equipment outlined in this agreement.

Whether NASA gets this money from Congress however remains unknown. It has not yet been appropriated.

This overall European project has been fraught with problems. It was first designed as a partnership with NASA. Then Obama pulled NASA out in 2012, and ESA switched to a partnership with Russia, which was to provide the rocket and lander. Then in 2022 Russia invaded the Ukraine and Europe broke off all its partnerships with Russia.

Since then ESA has signed a deal with the company Thales Alenia to build the lander.

As these political foibles were going on, the rover also had parachute issues that forced ESA to cancel its original launch date in 2022, using the Russian rocket.

It is likely Congress will approve this additional funding, though it seems to me that Europe should be able to afford paying for its own launch, especially if it is buying that service from the much cheaper U.S. market.

Another “rightwing COVID conspiracy theory” proves to be true

12:59 pm

Today's modern witch hunt
Burning witches: The debate technique used by
those in charge during the Wuhan panic

Since the very beginning of the COVID panic in 2020 many perfectly reasonable people, both inside and outside the medical community, suggested that COVID was artifically created and that the evidence strongly suggested its source was from a lab leak at the Wuhan Institute of Virology.

Worse, the evidence suggested that this work was partly funded by the United States itself — approved by federal bureaucrats like Anthony Fauci — that funnelled government contracts to China to do dangerous infectious disease research which that hostile nation could then use against us.

Unfortunately, those individuals found themselves routinely mocked as pushing a “rightwing COVID conspiracy theory,” with many finding their careers destroyed by blacklisting. During those dark times it was forbidden to ask any questions that went against the leftist government narrative that pushed the myths that COVID was a deadly perfectly natural disease, that lockdowns, masks, and social distancing were the only ways to stop it, and that in the end only the COVID jab could cure it.

We now know without question that those accepted wisdoms, enforced by brutal intolerance, were all wrong, and that the blackballed individuals who advocated otherwise were 100% correct.

Or to put it more bluntly, the only difference between a “rightwing conspiracy theory” and the truth is a few months.

This week we got another proof of this apt saying.

Earth-sized exoplanet discovered orbiting dwarf star 55 light years away

10:49 am

Using a number of ground-based telescopes worldwide, astronomers have discovered an Earth-sized exoplanet orbiting what the scientists label an “ultra-cool” dwarf star only about 55 light years away.

You can read the paper here.

Though Earth-sized, this exoplanet is not habitable. It orbits the star every 17 hours and is believed to be tidally locked, with one side always facing the star. More important, though this red dwarf star has likely existed for many tens of billions of years and will continue for many tens of billions of years into the future, the star is too dim and lacking in the kind of resources needed for life. It also drenches the planet with bursts of radiation, which is also believed to have stripped the planet of an atmosphere.

Potentially serious problem on BepiColombo Mercury mission

10:14 am

According to the European Space Agency (ESA), engineers have discovered what could be a potentially serious problem on BepiColombo mission that is presently on its way to Mercury.

The solar arrays and electric propulsion system on the Mercury Transfer Module are used to generate thrust during the spacecraft’s complex journey from Earth to Mercury.

However, on 26 April, as BepiColombo was scheduled to begin its next manoeuvre, the Transfer Module failed to deliver enough electrical power to the spacecraft’s thrusters.

A combined team from ESA and the mission’s industrial partners set to work the moment the issue was identified. By 7 May, they had restored BepiColombo’s thrust to approximately 90% of its previous level. However, the Transfer Module’s available power is still lower than it should be, and so full thrust cannot yet be restored.

The press release implies that this issue won’t prevent the spacecraft from entering orbit around Mercury as scheduled in December 2025, but one wonders how that could be if it doesn’t have sufficient power to do the proper course correction during its last major flyby of Mercury in September 2024. If it misses its precise route in ’24 it could miss Mercury entirely in ’25.

Engineers are analyzing the situation to see what can be done to get it to Mercury, while also trying to figure out what caused this power problem in the first place in order to fix it.
