Gehrels/Swift space telescope enters safe mode

The Neil Gehrels Swift observatory ceased science observations and entered safe mode on January 18, 2021, when one of its six reaction wheels experienced a failure.

It appears the other five reaction wheels, which function as gyroscopes to point the telescope accurately, are working properly. If engineers can’t recover the lost wheel, the telescope will still be able to operate with no problems.

Swift was launch seventeen years ago in order to solve the mystery of gamma ray bursts, which it did most successful. The man who most made the observatory possible, its principal scientist, Neil Gehrels, passed away in 2017, and to honor his memory the telescope was then named after him.

Freaky badlands on Mars

Freaky badlands on Mars
Click for full image.

Cool image time! The photo to the right, rotated and cropped to post here, was taken on November 18, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as “Danielson Crater Outcrops,” it shows us a perfect example of the strangeness and sometimes very forbidding terrain of Mars.

We are looking at the outcrop tops of many tilted layers, worn into curves semicircles with the convex side all pointing to the southwest. In the hollowed concave-side, dust and sand have accumulated and been trapped, sometimes forming small ripple dunes when there is enough space for the wind to get inside, as seen in the picture’s lower right.

Danielson Crater is 41 miles in diameter. The overview map below provides the context.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

NATO issues new space policy filled with blather

NATO on January 17th published a new space policy document that with a great deal of bureaucratic blather essentially says that space is important, NATO’s enemies threaten those assets, and NATO recognizes these facts.

You can read the full document here.

This is obviously a policy document so we should not expect it to lay out proposed or planned operational projects. At the same time, it is so filled with generalizations it really says very little. In a sense, the blather is designed to hide how little it says, besides the very obvious or the most common sense goals, such as for example making sure the equipment of all of NATO’s partners is compatible with each other. To give you a flavor, here is one quote:

NATO will identify and, if necessary, develop appropriate mechanisms, based on voluntary participation, to fulfil and sustain requirements for space support in NATO operations, missions and other activities in the above functional areas. Allies’ capabilities, and, if necessary, trusted commercial service providers, should be leveraged to meet these requirements in the most secure, efficient, effective and transparent manner.

In plain English, NATO wants the cooperation of both private and government space entities to make sure it can function fully in space. As I said, stating the obvious.

The language actually tells us more about the foggy and inefficient thinking among DC and Pentagon bureaucrats. They can’t write clearly because they really don’t think clearly.

Still, the policy outlined essentially commits NATO to support a thriving infrastructure in space, from both the private and governmental sectors. The policy’s strong apparent support for “voluntary” private space is especially encouraging.

The policy’s position against aggressive actions by others, such as Russia and China, is also somewhat encouraging, though its expression in such mealy-mouth language suggests a fundamental lack of commitment that could be worrisome. Russia’s response to this new policy statement was not so vaguely put:

Russian Foreign Ministry Spokeswoman Maria Zakharova took NATO to task over its space policy paper at a briefing on Thursday, branding it as slanted and incendiary. According to her, the document entitled NATO’s Overarching Space Policy, which was published on January 17, covers the Western-led bloc’s priorities in space. “The document is one-sided and in fact incendiary as it is based on destructive beliefs of the US-led NATO members who have an important role in space,” Zakharova emphasized.

I suspect, based on Zakharova’s comments, that Russia has determined from the new policy statement that NATO’s policy is weak, and that Russia can therefore continue to push the envelope against it and the western powers, just to find out exactly how much it can get away with.

Yutu-2 scientists find soil “cloddy” during its journey

Chinese scientists today published a paper describing results from Yutu-2’s two year journey on the far side of the Moon, with the most interesting discovery being that the soil is “cloddy” there.

They found that the bearing property of the regolith is similar to that of dry sand and sandy loam on Earth, stronger than the typical lunar soil of Apollo missions.

But they estimated, based on the cloddy soil observed in Yutu-2’s wheels, that the soil there is stickier than the landing site of its predecessor Chang’e-3 which soft-landed on the moon’s Bay of Rainbows in Dec. 2013, according to the study.

The researchers attributed the increased soil cohesion to the higher percentage of agglutinates in the regolith, which make the soil particles more likely to hold together when ground by the wheels.

Since the blocky soil has adhered onto the rover’s wheel lugs instead of its meshed surface, they suggested that the lug’s surface could be coated with a special anti-adhesion material in future missions to improve the machine’s ability of traction.

The rover also traveled by the number of small and relatively fresh secondary craters.

Yutu-2 continues to operate. It is at present in hibernation during the lunar night, and will resume operations when the Sun comes up in about a week or so.

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.

Radian raises $27.5 million to develop single-stage-to-orbit spaceplane

Capitalism in space: The startup Radian Aerospace announced yesterday that it has raised $27.5 million in private investment capital to fund the development of a single-stage-to-orbit spaceplane it dubs Radian One.

Radian has disclosed few technical details about the Radian One design. The seed round “essentially helps us transition more robustly into the hardware development phase,” Holder said. The company’s work to date has focused on the conceptual design and a few key technologies, such as test-firing “critical elements” of the vehicle’s main propulsion system.

The company said it has launch service agreements for Radian One with commercial space station developers, in-space manufacturers, satellite, and cargo companies, as well as agreements with the U.S. government and selected foreign governments. It did not identify specific customers, value of any such agreements or schedules for delivering those launch services.

Company officials seem confident they can do this. Their chief technology officer worked on the failed 1990s single-stage-to-orbit X-33 project, and is convinced the advances in technology since now make such a spaceplane possible.

We shall see. Radian faces stiff competition, as it is one of more than a hundred new orbital rocket companies. Its advantage, if successful, is its completely reusable airplane-like design.

SpaceX now blocked from Pakistan; OneWeb signs deal to operate in India

Capitalism in space: Two stories this morning suggest that the competition between the internet satellite constellations Starlink and OneWeb is being partly influenced by local politics, with the influence favoring OneWeb and hindering SpaceX.

First, Pakistan ordered SpaceX to stop taking preorders from its citizens for its Starlink system.

The Pakistan Telecommunication Authority (PTA) said in a Jan. 19 news release that “Starlink has neither applied for nor obtained any license from PTA to operate and provide internet services” in the country. The telecoms regulator advised the general public to refrain from pre-booking the service in Pakistan through Starlink or associated websites.

This order follows a similar decree in India. Like India, SpaceX had apparently not been granted a license or permit to take preorders. SpaceX has now been blocked entirely from the subcontinent by the governments of both countries.

Second, OneWeb and Hughes announced a partnership agreement to distribute its internet service in India.

In the statement, OneWeb’s CEO Neil Masterson said the company would partner with Hughes to “offer high-speed, low-latency satellite broadband solutions and contribute to the Digital India vision”. OneWeb’s constellation, he said, would cover the length and breadth of India, from Ladakh to Kanyakumari and from Gujarat to the Northeast and bring secure solutions to enterprises, governments, telcos, airline companies and maritime customers. “OneWeb will invest in setting up enabling infrastructure such as Gateways and PoPs in India to light up the services,” he added.

According to the announcement, OneWeb intends to start offering its service this year.

OneWeb is half-owned by the Indian-based Bharti group. It seems that this connection with India has greased the bureaucratic wheels in that country for OneWeb, allowing it begin offering its services there. It also appears that this same connection with India is likely one reason both India and Pakistan have put a break on SpaceX’s operations.

Flight dates for SpaceX’s next two manned flights to ISS revised

Capitalism in space: A NASA official yesterday announced that the flight dates for SpaceX’s next two manned flights have been firmed up, with the private commercial Axiom AX-1 flight delayed from February 21st to March 31st, followed two weeks later by NASA’s own manned mission on April 15th.

Axiom has also noted that this commercial flight, piloted by a former NASA astronaut and carrying three passengers, will be its only commercial manned flight in ’22.

…Commanded by former NASA astronaut Michael López-Alegría, Ax-1 will only carry private citizens. Each paying $55 million for the privilege, the mission’s three customers are Larry Connor, Mark Pathy, and Eytan Stibbe – all businessmen who’ve respectively amassed multmillion-dollar fortunes in real estate; entertainment and shipping; and military equipment and venture capitalism.

Their Dragon spacecraft will be Resilience, making its third flight.

Axiom’s next private commercial flight has now been delayed until ’23.

Upper stage of ABL rocket explodes during ground test

Capitalism in space: During a ground test of the upper stage of ABL Space Systems RS1 rocket an “anomaly” occurred that caused an explosion, apparently destroying the stage.

No one was hurt, but the company has released few details about what happened. We do not know if the explosion occurred during an engine static fire test, or during a pressure test of the stage’s tanks.

The company’s first launch was in October supposed to happen in December, then was shifted to January. This incident will certainly delay it further.

Ingenuity’s 19th flight delayed due to Martian weather

Because of the early arrival of the fall dust storm season, the Ingenuity engineering team decided to delay the helicopter’s 19th flight on January 5th, rescheduling it to no earlier than January 23rd.

In the days following the flight delay, the dust storm moved over Jezero crater, and we were able to clearly see its effects in both MEDA data and from orbit (Figure 1). Most notable was a sharp drop in air density – about a 7% deviation below what was observed pre-dust storm. This observed decrease would have put density below the lower threshold of safe flight and would have imparted undue risk to the spacecraft. We also observed the effect of dust in the amount of sunlight absorbed by Ingenuity’s solar array, which fell well below normal “clear sky” levels, a drop of about 18%.

Apparently the storm has now dissipated, allowing the new flight date.

Though this flight postponement occurred two weeks ago, today’s update appears to be the first public announcement, which has been typical of the Ingenuity team. They generally announce planned flights just before take-off, but then provide no detailed update on what happened, sometimes for weeks.

Freedom is under siege, and the besiegers have now told us they have no mercy

Liberty under siege
Liberty under siege.

For many years I deeply and sincerely believed that many rank-and-file Democrat voters honestly did not know how corrupt and power-hungry the political leaders of their party had become. I thought that if I could simply get them to see the clear evidence of misbehavior and abuse of power that has been going on in the Democratic Party without check since Bill Clinton was president, they would reconsider their voting habits and abandon their support of that party.

I thought that the vast majority of Democrats were decent people who opposed oppression and intolerance and simply were unaware that they were voting for it when they supported the Democratic Party.

I now know unequivocally that I was wrong. Two stories in the past week illustrate bluntly that a large number of ordinary Democrats, maybe even a majority, are eager supporters of oppression and intolerance and dictatorship. They like the corruption and abuse-of-power coming from Democratic Party politicians. They even want more of it.
