Galaxies without end

Webb infrared image of galaxies without end
Click for original image.

Cool image time! The mid-infrared picture to the right, cropped, reduced, and sharpened to post here, was taken by the Webb Space Telescope during its commissioning process last year shortly after launch, and was used to calibrate the Near-InfraRed Imager and Slitless Spectrograph (NIRISS) instrument, the very same instrument that for the past two weeks was not in operation because a cosmic ray had scrambled its software, requiring a reboot to fix it. From the caption:

The large spiral galaxy at the base of this image is accompanied by a profusion of smaller, more distant galaxies which range from fully-fledged spirals to mere bright smudges. Named LEDA 2046648, it is situated a little over a billion light-years from Earth, in the constellation Hercules.

While the large spiral is majestic, the tiny galaxy smudges are actually more important. Astronomers are right now scrambling to determine their distance and age in order to better understand what the universe was like, thirteen-plus billion years ago. So far the Webb data of these very early galaxies suggests that in this early universe there were many more fully formed galaxies, similar to ones we see in our time, than any theory of the Big Bang had predicted.

Ingenuity successfully completes 41st flight

9:40 am

Overview map
Click for interactive map.

On January 27, 2023, the Mars helicopter Ingenuity successfully completed its 41st flight, flying about 600 feet total in an out-and-back flight that took 109 seconds, slightly longer in length and time than originally planned.

You can watch a very short animation from a handful of the pictures taken during the flight at the first link above. The green dot on the overview map to the right marks Ingenuity’s position before and after the flight, the blue dot Perseverance’s present location. The green line indicates the flight’s approximate path, designed to scout the route that Perseverance intends to follow, as indicated by the red dotted line. The actual flight path has not yet been published. I will add it to this map when the Ingenuity science team provides it.

Expect the next flight to duplicate this one, except it will likely not return but land somewhere out ahead.

Astronomers discover twelve more Jupiter moons

9:21 am

In reviewing ground-based data from 2021 and 2022, astronomers have discovered another twelve Jupiter moons, bringing that planet’s total moon population to 92.

All of the newly discovered moons are small and far out, taking more than 340 days to orbit Jupiter. Nine of the 12 are among the 71 outermost Jovian moons, whose orbits are more than 550 days. Jupiter probably captured these moons, as evidenced by their retrograde orbits, opposite in direction to the inner moons. Only five of all the retrograde moons are larger than 8 kilometers (5 miles); Sheppard says the smaller moons probably formed when collisions fragmented larger objects.

One newly discovered moon, dubbed Valetudo, is about 3,000 feet across and orbits in a retrograde orbit that crosses the orbits of several other moons that orbit in the opposite direction. As the article notes, “This highly unstable situation is likely to lead to head-on collisions that would shatter one or both objects.”

Webb instrument back in operation

9:13 am

Engineers have returned NIRISS, the near infrared spectrograph instrument on the Webb Space Telescope, to full operation after rebooting its software and determining the cause of the problem.

On Jan. 15, NASA’s James Webb Space Telescope’s Near Infrared Imager and Slitless Spectrograph (NIRISS) experienced a communications delay within the science instrument, causing its flight software to time out. Following a full investigation by NASA and Canadian Space Agency (CSA) teams, the cause was determined to likely be a galactic cosmic ray, a form of high-energy radiation from outside our solar system that can sometimes disrupt electrical systems. Encountering cosmic rays is a normal and expected part of operating any spacecraft. This cosmic ray event affected logic in the solid-state circuitry of NIRISS electronics known as the Field Programmable Gate Array. Webb engineers determined that rebooting the instrument would bring it back to full functionality.

After completing the reboot, NIRISS telemetry data demonstrated normal timing, and to fully confirm, the team scheduled a test observation. On Jan. 28, the Webb team sent commands to the instrument to perform the observation, and the results confirmed on Jan. 30 NIRISS is back to full scientific operations.

Engineers actually have a name for such cosmic ray incidents that effect software. They call it a bitflip.

Developments at the Houston Spaceport industry park

7:44 pm

Link here. The article gives a detailed review of the various space-related businesses (Axiom, Intuitive Machines, Collins Aerospace) that have set up operations at this industry park focused on attracting space companies to the Houston area.

The park in a sense in misnamed, as it isn’t a launch facility. However, it is now building a taxiway that will connect the park directly to Ellington Airport, which for these businesses will help facilitate the transport of large space station modules and lunar landers.

That ain’t snow on Mars

That ain't snow on Mars
Click for original image.

Today’s cool image proves once again that you must never too quickly jump to any conclusions when you first look at a picture from space. The photo to the right, cropped, reduced, and sharpened to post here, was taken on November 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

At first glance it appears that those ridges are topped with patches of snow or frost. Not. What appears white in this black and white photo is immediately revealed to be light-colored dust in the color image.

According the label assigned to this image by the science team, these ridges represent layers, likely tilted steeply so that when exposed they form the layered cliff edges where that light dust has now gathered.

The overview map below provides further evidence that the white patches are dust, not snow.

The next chapter in my own personal blacklisting story

12:01 pm

The ARA: An organization run by bullies
The ARA: An organization run by bullies

This past Saturday, January 28, 2023, another chapter in my own personal blacklisting saga took place. On that day the Arizona Regional Association (ARA), a division of the National Speleological Society, the country’s national organization for cavers, held its annual winter technical meeting at Kartchner Caverns in Arizona.

It is this same organization had blacklisted me and two other individuals in November 2021 because they did not like our opinions about COVID. Its leadership therefore assumed that it also the right to eject us from the public event on Saturday. It was our intention to show them they were wrong.

The goal of the winter technical, which has been occurring annually for about a half century, is to allow southwest cavers to present papers highlighting their research and projects during the past year. While intended mostly for Arizona cavers, it has not been unusual for others from other parts of the country to present, especially if their work has some connection with Arizona. Consider it a very informal kind of scientific conference.

Thus, this event has always been open to the public, and in fact has always been designed as a form of outreach.

The Wuhan panic had unfortunately caused the winter technical to be canceled in 2021 and 2022. Thus, the January 2023 event was to be the first in-person winter technical since 2020.

It was also going to be the first in-person winter technical since this organization had blacklisted myself and two others. » Read more

Today’s blacklisted American found innocent of federal trumped up charges

The Houck Family: Targets of FBI harassment and arrest
The Houck Family: Targets of FBI harassment and arrest.

Back in September 2022 I wrote an essay entitled “The rising federal Gestapo” in which I described the numerous recent stories of the Biden administration using the FBI and the Department of Justice as weapons to harass its political opponents, either by conducting armed raids on their homes and persons, or by trumping up false charges against them.

Mark Houck, the father in the picture the right, was one of those under attack. Not only was his home raided by an FBI SWAT team, terrifying his children, but Houck was arrested on a trumped up charge of physically attacking a worker at an abortion clinic, a charge that had other courts had already dismissed as spurious.

The good news yesterday is that Houck has been found innocent of that trumped up charge.

At first it appeared the jury was deadlocked, but that changed instantly when one juror was replaced with an alternate. Within an hour the not-guilty verdict was in, strongly suggesting that juror had had a political ax to grind and was refusing to follow the facts of the case or the judge’s instructions.

As I wrote in that September essay,

In the past two years the effort by Democrats to portray Republicans criminals and traitors, merely because they disagree with Democratic Party policy, has become normalized. To Democrats today, if you are a Republican you are a fascist, an insurrectionist, a traitor, a criminal, and evil. Your rights are voided and they have the right to arrest you, at any time.

The Biden administration tried to void Mark Houck’s rights. It failed in court. Was this vicious effort however a failure? I say no, because 1) the Biden administration remains free to continue this abuse of power and 2) conservatives have now been put on notice that, at any moment, their lives could be torn apart by these thugs.

In fact, this short post is only posted to give an update on a previous column. It is not today’s daily blacklist column, which will follow shortly and will give perfect example of how the abusive power-hungry in our culture now routinely abuse their power against any who oppose them.

Perseverance completes placement of first ten samples for later pick up

9:36 am

Overview map
Click for interactive map.

On January 29, 2023 the Perseverance science team completed the placement of the first ten core samples on the floor of Jezero Crater.

On the overview map to the right, the green outline indicates the location of this sample depot. The blue dot marks Perseverance’s present location, while the green dot marks Ingenuity. The red dotted line shows the planned route up onto the delta, which is Perseverance’s next goal.

The titanium tubes were deposited on the surface in an intricate zigzag pattern, with each sample about 15 to 50 feet (5 to 15 meters) apart from one another to ensure they could be safely recovered. Adding time to the depot-creation process, the team needed to precisely map the location of each 7-inch-long (18.6-centimeter-long) tube and glove (adapter) combination so that the samples could be found even if covered with dust. The depot is on flat ground near the base of the raised, fan-shaped ancient river delta that formed long ago when a river flowed into a lake there.

This mapping will be used by a future Mars helicopter to precisely land by each sample, grab it, and then take it to the ascent vehicle for return to Earth.
