Time for another of the many cool images from Mars that suggest the presence of buried glacial ice. The photo to the right, rotated, cropped, and reduced to post here, shows an unnamed crater in the cratered southern highlands of Mars at about 44 degrees south latitude. Taken on October 2, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), the crater sits at the very southernmost point of the Tharsis Bulge where the Red Planet’s four more distinctive giant volcanoes are located.

The crater is also in the middle of the 30 to 60 degree mid-latitude bands where scientists have detected many features that suggest glaciers, including a large number of craters that appear to have ice filling their interior.

Does the material in this crater’s floor suggest eroding and sublimating ice to you? It does to me. The second image below zooms in at full resolution at the north-south trench and the strange patterned terrain to its east.

India’s space agency signs deal with private Indian smallsat company

9:28 am

The new commercial division of India’s space agency ISRO, dubbed the Department of Space (DoS), has signed a development deal with a new private Indian smallsat startup, Agnikul Cosmos, that has plans to build a rocket that will launch from Kodiak, Alaska in ’22.

More information here.

The agreement is designed to provide technical support to the company. Initially the company had only planned to launch from an ISRO launch facility in India. It now appears they are widening their goals to include an U.S. site as well, probably to encourage sales to American satellite companies.

Their rocket, 3D printed, also appears very small, and targets the smallest size smallsat market.

Hubble captures 20-year fading of planetary nebula

The fading of the Stingray Nebula

Astronomers using the Hubble Space Telescope have now tracked the spectacular fading of the Stingray Nebula, which when it was discovered in the mid-1990s was labeled the youngest such object ever found.

Astronomers have caught a rare look at a rapidly fading shroud of gas around an aging star. Archival data from NASA’s Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift rate of change in a planetary nebula is exceeding rare, say researchers.

Images captured by Hubble in 2016, when compared to Hubble images taken in 1996, show a nebula that has drastically dimmed in brightness and changed shape. Bright blue fluorescent tendrils and filaments of gas toward the center of the nebula have all but disappeared, and the wavy edges that earned this nebula its aquatic-themed name are virtually gone. The young nebula no longer pops against the black velvet background of the vast universe.

Astronomers have found that the central star had been heating precipitiously in the late 20th century, from 40K to 108K degrees Fahrenheit. Since then it has begun to cool. They think that flash of heat, caused by what they think was short period of helium fusion, caused the planetary nebula to brighten, and now fade.

Trump administration asks Senate to remove SLS requirement for Europa Clipper

8:55 am

The Trump administration has requested the Senate to change the language in its NASA spending bill to remove its requirement that Europa Clipper be launched on SLS.

NASA wants the option to launch the Europa probe using commercial rockets, such as SpaceX’s Falcon Heavy. It also says that there are technical reasons that make using SLS problematic, and worse, the agency simply does not have enough SLS rockets to fly its planned (but unfunded) manned Artemis missions and also launch Europa Clipper.

The House has already removed that requirement in its version of the bill. The Senate has not, probably because the chairman of the Senate Appropriations Committee, Richard Shelby (R-Alabama), is a big fan of SLS (much of it built in his state), and has acted for years to pump money into that project.

If the requirement is not removed, Europa Clipper’s launch will likely be delayed by several years, and cost $1.5 billion more.

First sunspot image from Inouye Solar Telescope

Sunspot image taken by Inouye Solar Telescope

The science team for the new Inouye Solar Telescope, now in the final phase of construction, has released the telescope’s first high resolution sunspot image.

The image is to the right, reduced to post here, and was taken almost a year ago, on January 28, 2020.

“The sunspot image achieves a spatial resolution about 2.5 times higher than ever previously achieved, showing magnetic structures as small as 20 kilometers on the surface of the sun,” said [Dr. Thomas Rimmele, the associate director at NSF’s National Solar Observatory (NSO)].

The image reveals striking details of the sunspot’s structure as seen at the Sun’s surface. The streaky appearance of hot and cool gas spidering out from the darker center is the result of sculpting by a convergence of intense magnetic fields and hot gasses boiling up from below.

…This sunspot image, measuring about 10,000 miles across, is just a tiny part of the Sun. However, the sunspot is large enough that Earth could comfortably fit inside.

The start of official telescope operations is set to begin in ’21, and had been delayed because of the Wuhan flu panic. Construction had begun in ’13.

World’s largest drone unveiled for launching smallsats

8:41 am

Capitalism in space: Aevum, a new entrant in the race to provide low cost reusable launch services for the emerging smallsat market, has unveiled the world’s largest drone, dubbed RAVN-X, designed to take off and land at airports and then release an upper stage rocket that takes the satellite into orbit.

RAVN-X is not the first air-launched rocket catering to the “smallsat” market. Northrop Grumman’s Pegasus system has flown dozens of times since the 1990s. Virgin Orbit’s LauncherOne failed in its first launch attempt earlier this year, will try again later this month with an attempt to launch 10 NASA-funded “CubeSats”—small satellites that typically weigh less than 10 kilograms each. But both Pegasus and LauncherOne use traditional, piloted jets, whereas Aevum’s driverless drone is unique, says Phil Smith, a senior analyst at Bryce Space and Technology, a consulting firm. Still, Smith says, RAVN-X is flying into a crowded market, with more than 100 small launch vehicles in development. “There’s a plethora of systems out there,” he says. “There isn’t room for more than perhaps three to five or so.”

According to the article, Aevum already has a billion dollars in launch contracts with the Space Force. They are targeting ’21 for their first orbital flight.

Nandi Bushell – Rock and Grohl

6:01 pm

An evening pause: The musical talent and passion are both outstanding. The shallow philosophy, when compared to Aristotle or Plato or Moses (to list only a few), is kind of sad to watch. She really believes that life is that simple. As a child such shallow passion is fine. I fear however that in the arriving dark age no one will ever do anything to make her think more deeply.

Hat tip Mike Nelson.

Strong evidence in Michigan that many ballots were scanned multiple times

5:09 pm

An IT contractor who worked in Detroit at the location where votes were being tabulated has testified by sworn affidavit and in public testimony before Michigan legislatures that she saw an estimated 30,000 ballots scanned multiple times, illegally.

On November 10, Carone said in an affidavit that she witnessed “nothing but fraudulent actions take place.” “I observed numerous employees, city workers, running batches of ballots through the tabulators countless times, without discarding them first,” Carone said during the Wednesday evening hearing. She testified next to Rudy Giuliani, the personal attorney to President Trump, who has been leading most of the litigations efforts pertaining to the election.

Carone testified that on Election Day, the vote tabulating machines would jam up to three times an hour. When the machines would jam, election officials were supposed to reset the count on the machines to ensure that no ballots were scanned more than once, explained the witness. “Instead of discarding, they were just rescanning, rescanning, rescanning. Counting ballots nine to 10 times,” Carone said. She also said there were more than 20 tabulating machines at her ballot counting center.

Once again, this testimony does not prove, on its own, that the election was stolen. It does however demonstrate strong evidence that a full audit, of at least the Detroit voting center, is necessary before any result can be certified.

Strong evidence of election tampering in Arizona in sample audit of 100 ballots

4:40 pm

After the Republican Party was allowed to do an audit of 100 random ballots and found one voted changed from Trump to Biden, and another Trump vote discarded, election officials have agreed to do an expanded audit of 2,500 ballots.

Ward’s lawyers say the inspection of 100 ballots found that one person’s vote for Trump was ultimately recorded as a Biden vote and that another person’s vote for Trump was cancelled when the reproduced ballot contained votes for both the Republican incumbent and a write-in candidate.

The result? An increase in Biden’s margin by 3%, a change easily enough to overturn an election decided by about a 1/2 percent.. For this reason the election board did not wait for a court order but decided to go ahead with a larger audit.

Though this AP story goes out of its way to minimize the findings here, it is quite alarming to find this much error in only 100 ballots. Anyone (whether Republican or Democrat) should be alarmed and demanding a review, if only to protect the sanctity of all future elections. Anyone that objects, at all, is revealing themselves to be someone who does not want fair elections, and is probably eager to have elections stolen.

Strong video evidence of election law violations in Georgia during count

3:46 pm

In testimony today before the Georgia state senate, the Trump legal team showed evidence from CCTV cameras of almost two hours of vote counting occurring during a period when all Republican counters and pollwatchers as well as the media had been told to leave because counting was going to cease.

According to Georgia election laws, no votes can be counted without the presence of representatives from both parties along with the pollwatchers and the press. Moreover, the law requires that the chain of possession of all tabulated votes be properly maintained. During the two hours of illegal tabulation, it appears that all of the counted ballots came from four suitcases with no provenience that were pulled from beneath a table where they had been hidden earlier in the day.

Based on the pace of tabulating, the number of ballots counted during those two hours was more than enough to swing the results one way or the other. That all Republicans had been ushered away suggests the ballots were not for Trump.

Does this prove the election was stolen? No, not on its own. However, it does make the entire election result questionable. And if nothing untoward was going on, it behooves the individuals shown on this video to come forward to explain and justify what was done. Until they do so, the Georgia vote count is not trustworthy.

I have embedded below the fold the testimony, with th video presented during this testimony.
