“What the heck?!” swirls on Mars

1:33 pm


Click for original image.

Time for another “What the heck?!” image on Mars. The picture to the right, cropped to post here, was taken on January 6, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is what the science team calls a “terrain sample,” which means it wasn’t taken as part of any specific scientific investigation and requested by a scientist. Instead, it was taken to fill a gap in MRO’s schedule. In order to maintain the camera’s proper temperature it is necessary for it to take regular pictures, and sometimes if there is a gap between requested images the science team picks something almost at random to fill the gap.

Sometimes the picture results in something relatively uninteresting. More often they try to pick something intriguing but not yet of interest to any particular researcher. With today’s cool image they certainly found something intriguing, so much so that I haven’t the faintest idea what is going on here.

Clearly, the tan swirls lie on the higher topology, and could be dust covered. The darker hollows in between could be darker because they are so, or because they are in shadow.

Stop participating in the delusions of the insane

1:01 pm


“Lily” Mestemacher

In a perfect example of the modern madness of our time, when a bearded heavy-set man using the name “Lily” Mestemacher was arrested in Arkansas for making bomb threats against a location in Mississippi, the local news organization reporting the story in Mississippi used female pronouns to describe him because he claimed he was a woman. To quote that February 13, 2023 news report:

On February 10th, Mestemacher was transported to Oxford where she was booked on the aforementioned warrant. She was taken before a Lafayette County Justice Court judge for her initial bond hearing and issued a $50,000 bond. [emphasis mine]

His arrest mugshot is to the right. This is a man. Just because he is somewhat deranged and wants to make believe he is a woman does not require that local news organization, called The Local Voice, to participate in that derangement.

India’s government plans to sell tourist tickets on its future manned flights

10:40 am

The new colonial movement: It appears that once it completes its first manned mission in space, dubbed Gaganyaan, India’s government space agency ISRO intends to sell tourist tickets on future manned flights.

[Union Minister Jitendra] Singh, who also holds the portfolios of Personnel, Public Grievances and Pensions, informed the House that the objective of India’s maiden human spaceflight programme, ‘Gaganyaan’, is demonstration of human spaceflight capability to low earth orbit (LEO), which is a precursor to the future space tourism programme. “The ISRO has carried out a few feasibility studies for a sub-orbital space tourism mission,” the Union Minister revealed while announcing that after the accomplishment of the ‘Gaganyaan’ mission, activities towards space tourism would be firmed up.

Selling commercial tickets on its spacecraft would be completely in line with ISRO’s decades-long policy of trying to make money from its space capabilities. Whether this action however will help or hinder India’s independent space industry remains unclear. Like NASA a decade ago, there is a turf war in ISRO over whether to cede power to private enterprise, or hold it entirely in ISRO’s grip. If ISRO sells manned spaceflight tickets it will make it harder for private tourism companies to gain investment capital.

Perseverance’s depot of core samples, ready for pickup

10:30 am

Mosaic of Perseverance's core sample depot
Click for original image.


Overview map
Click for interactive map.

The Perseverance science team yesterday released the annotated mosaic above, cropped to post here, showing the scattered depot of core samples the rover deposited on the floor of Jezero Crater for later pickup some time next decade for return to Earth.

The overview map to the right shows the context. The blue dot marks Perseverance’s position when it took the picture, on January 31, 2023. The green dot marks Ingenuity’s location at that time. The yellow lines indicate the approximate area covered by the mosaic. The green outline indicates the area of the depot.

Eight of those tubes are filled with rock and regolith (broken rock and dust), while one is an atmospheric sample and one is a “witness” tube. The rover photographed the depot using the Mastcam-Z camera on the top of its mast, or “head,” on Jan. 31, 2023. The color has been adjusted to show the Martian surface approximately as it would look to the human eye.

The location of each tube was carefully mapped because it is possible wind will cover them with dust in the decade-plus before pickup. This mosaic will also act as a guide for the future Mars helicopters that will arrive to grab the core samples and bring them to an ascent spacecraft that will bring them back to Earth.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Imaging satellite builder Maxar signs contract with Umbra to use its radar satellites

10:02 am

Maxar, which operates a constellation of high resolution optical imaging satellites for commercial and military use, has now signed a contract with Umbra, which operates a constellation of high resolution radar satellites for commercial and military use.

The partnership will allow Maxar to directly task Umbra’s satellites and integrate synthetic aperture radar (SAR) data into its portfolio of Earth intelligence products and services, Tony Frazier, head of Maxar’s public sector Earth intelligence, told SpaceNews.

SAR is a specialized form of remote sensing that has been in growing demand since Russia’s invasion of Ukraine. SAR satellites can capture images at night, through cloud cover, smoke and rain — conditions that impair traditional optical satellites like those operated by Maxar.

The contract will give Maxar “assured access” to the soon-to-be launched six and seven satellites in Umbra’s constellation.

Essentially, this deal enhances Maxar’s value. Its main customer is the U.S. military, and it can now offer that military a more enhanced observation capability. Umbra meanwhile gets a major customer quickly, rather than having to pitch its product to multiple potential buyers. Its radar product is also enhanced, because it will now come automatically partnered with optical imagery.

Dislodged fuel filter identified as cause of Virgin Orbit launch failure

9:42 am

Virgin Orbit yesterday revealed that a dislodged fuel filter in LauncherOne’s upper stage caused the failure of the rocket to reach orbit during its January 9, 2023 launch from Cornwall, UK.

The data is indicating that from the beginning of the second stage first burn, a fuel filter within the fuel feedline had been dislodged from its normal position. Additional data shows that the fuel pump that is downstream of the filter operated at a degraded efficiency level, resulting in the Newton 4 engine being starved for fuel. Performing in this anomalous manner resulted in the engine operating at a significantly higher than rated engine temperature.

Components downstream and in the vicinity of the abnormally hot engine eventually malfunctioned, causing the second stage thrust to terminate prematurely.

The rocket thus did not have enough velocity to reach orbit, and fell in the ocean.

No word yet on when the company will next launch, though it has said that launch will be from Mojave, California.

  • Russia resumes prepping next Soyuz for launch

    • An inspection of the outside of the spacecraft’s cooling system found no damage or drilled holes. Expect the launch to occur before the end of February, relative close to its previous launch date of February 19th. As this is the lifeboat for three occupants of ISS, delaying its launch increases other risks.

SpaceX abandons plan to convert floating oil platforms into Starship/Superheavy landing spots

4:18 pm

SpaceX has decided not to convert the two floating oil rigs it had purchased in 2020 into Starship/Superheavy landing platforms, and has sold both.

According to SpaceX CEO Gwynne Shotwell,

Shotwell said the company needed to first start launching Starship and better understand that vehicle before building offshore launch platforms. “We really need to fly this vehicle to understand it, to get to know this machine, and then we’ll figure out how we’re going to launch it.”

She said she expected offshore platforms to eventually play a role to support an extraordinarily high launch cadence. “We have designed Starship to be as much like aircraft operations as we possibly can get it,” she said in the conference presentation. “We want to talk about dozens of launches a day, if not hundreds of launches a day.”

This is a perfect example of this company’s intelligent ability to focus on the most important problems now, instead of getting distracted by future issues and challenges it knows exists but are not the priority at this time.

A glacial river on Mars

2:01 pm

A glacial river on Mars
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a wonderful example of a glacier-filled canyon on Mars, the ice apparently flowing both along and around mesas as it carves its way downhill.

I think the downhill grade here is to the north, but this could be wrong for the two side canyons on the main canyon’s north side.

Not only is the material in the canyon likely ice, covered with a protective layer of trapped dust and ash that makes the glacier surface look so smooth, the mesa tops are likely impregnated with ice as well. The mesas however have little dust, so the plateaus have a mottled stippled look likely caused by sublimation of that underground ice.

The location of these canyons explains the presence of ice.

Today’s blacklisted Americans: Religious pro-lifers prevented from viewing Bill of Rights because National Archives forbids free speech

12:35 pm

The evil hat that Air & Space banned
An example of the evil pro-life clothing
banned by the National Archives

They’re coming for you next: Students and parents and others who had just attended the January 20, 2023 March for Life event in Washington were told by numerous National Archives security officials that day that they must remove or cover any pro-life shirts, jackets, hats, or buttons or they would be ejected from the museum.

From the lawsuit [pdf] filed by three of those pro-life individuals:

Plaintiff L.R., her mother, and her fellow classmates [about 35 people] were ushered through security and into the first group of visitors to enter the Rotunda where the Constitution and Bill of Rights are on exhibit.

…Approximately five minutes later, Plaintiff L.R. and her fellow classmates were suddenly approached by Defendant John Doe 1 who instructed Plaintiff L.R. and her classmates to remove all pro-life attire. John Doe 1 specifically instructed Plaintiff L.R. that she could not be wearing anything pro-life and that she must cover her shirt and not unzip it until she had left the National Archives. John Doe 1 also instructed Plaintiff L.R. and her other classmates to remove their pro-life buttons. John Doe 1 made other classmates standing near Plaintiff L.R. remove their pro-life hats. One such hat contained the inscription, “LIFE always WINS.” Another hat contained the inscription, “ProLife.” Plaintiff L.R. witnessed another guard participate in these instructions to her classmates and at no time did any of the other guards in the Rotunda intercede and provide contrary instruction.

Winter finally ends for Ingenuity

9:47 am

According to a detailed update today by Travis Brown, Chief Engineer of the Mars helicopter Ingenuity, the helicopter has now finally exited its difficult winter conditions that began in May 2022 and only ended at the end of January 2023.

One month to the day after the Dec. 24 flight attempt, Ingenuity did something it hadn’t done during the previous 260 sols – it slept “warmly” through the entire night. Data leading up to this event had suggested that such a survival was possible, but 8 long months of winter had tempered the team’s optimism. When Ingenuity’s team reviewed the downlinked data, they found that not only had it started living through the night, but had actually begun to bank power in its batteries. We’ve now seen end-of-sol states of charge in our batteries of more than 90% — an unbelievable number just days earlier. All the above means our sleepy friend has finally awoken from its long winter malaise, just in time to race up the Jezero Crater Delta and provide valuable advanced imaging for Perseverance.

Brown describes in detail their struggle for the past eight months to keep Ingenuity alive. That information is going to be crucial in designing future Mars helicopters, including the ones that will return to Jezero Crater sometime in the next decade to grab the core samples Perseverance has deposited for pick up and return to Earth.
