Pushback: Nationwide group fights university blacklisting of those who refuse COVID shots

11:49 am

No College Mandates logo

Bring a gun to a knife fight: A new group, dubbed No College Mandates, is now campaigning nationwide against the effort of universities to blacklist anyone who has not gotten any COVID shots.

Formed in December 2021, the organization recently launched a protest letter campaign to colleges that still require the vaccine and boosters and have “forced these young adults into compliance,” according to a news release.

“We decided to target colleges because they were among the first educational institutions mandating vaccines,” Lucia Sinatra, co-founder of the group, told The College Fix via email. “Colleges have known since August 2021 that the virus can transmit equally between unvaccinated and vaccinated individuals yet they mandated boosters and some have begun to mandate the bivalent booster,” she said.

The organization has sent its protest letter to over 300 colleges. The letter to Yale is typical, noting in detail how the CDC has now admitted that the jab does not stop transmission and that the mandates were pointless. Yet the college still insists that teachers, students, and visitors all must get the jab, plus at least one booster. As the letter notes, these senseless rules do nothing to prevent the Wuhan flu, while normalizing blacklisting.

China’s Long March 5B rocket with new space station module is now at launchpad

10:16 am

China’s Long March 5B rocket had now been rolled out to its launchpad, carrying the new Mengtian module for China’s Tiangong-3 space station.

The launch is presently scheduled for October 31, 2022. Assuming China has not upgraded the engines on the rocket’s core stage, that stage will tumble back to Earth, uncontrolled, sometime in the following week. Since it is large enough to survive re-entry, it will hit the ground, thus threatening every habitable location under its orbital path. By allowing this to happen China violates the Outer Space Treaty, to which it is a signatory.

Nor will this likely be the last time China does this. Though this module completes China’s station, as presently designed, this will not be the last Long March 5B launch. China plans to use it put its Hubble-class space telescope into orbit, as well as other things.

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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

Relativity edges closer to first launch

9:59 am

Relativity has begun stacking its Terran-1 rocket with a goal of soon rolling it out to the launchpad for static fire tests.

The launch date itself remains uncertain. Though the company hopes to lift-off before the end of the year, it also has not committed to that goal.

“We are confident in our tech readiness to launch this year, and we’re still marching toward that,” Ellis said. “But there are a few external factors as we’re getting close to the end of the year that could impact the timeline for us. It’s not a guarantee, but it could.”

Those external factors include other spaceport users in Florida, including uncertainty around the mid-November launch of NASA’s Space Launch System rocket, and blackout periods as part of the military’s Holiday Airspace Release Plan. This effectively precludes launches around Thanksgiving, Christmas, and New Year’s Day due to the high volume of airline flights.

Ellis said the company is progressing well toward securing a launch license for “Good Luck Have Fun,” and noted that the Federal Aviation Administration accepted its methodology for debris mitigation as well as its trajectory analysis software.

The article at the link adds some additional details about the company’s plans. This Terran-1 rocket appears to be its equivalent of SpaceX’s Falcon-1. The company plans to quickly replace it with its much larger Terran-R rocket, comparable to the Falcon-9 in power and price. And it already has won $1.2 billion in launch contracts, and hopes to launch within two years.

I wonder if Terran-R will launch before Blue Origin’s much touted but repeatedly delayed New Glenn rocket. The article itself appears to think so, since it focuses entirely on the competition between SpaceX and Relativity, as if Blue Origin and New Glenn do not even exist.

ISS dodges space junk from Russia’s November 2021 anti-satellite test

9:46 am

In order for ISS to avoid one of the approximately 585 pieces of space junk still in orbit that were produced when Russia destroyed its defunct Cosmos 1408 satellite in a November 2021 anti-satellite test, engineers fired the engines of a docked Progress freighter yesterday for just over five minutes.

Without the burn the debris would have flown within three miles of the station, too close for comfort or anyone’s margin of error.

According to a report in September, of these 585 pieces, most will burn up in the atmosphere by ’25, with only 38 pieces left afterward to pose a threat to other operating satellites and manned spacecraft.

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.

Researchers figure out how to make the Starlink constellation a GPS-type constellation

9:37 am

Researchers working independent from SpaceX and without any of the company’s proprietary data, have found a way to turn the Starlink internet constellation — now about 3,000 satellites strong — into a method of pinpointing one’s location, thus making it an alternative to GPS-type satellites.

To be clear, no one is accessing Starlink user data here. The sync sequences are just strings of timings and other data that the machines use to stay in touch — the payload data is entirely separate.

In the paper, due to the fact that the signal was being targeted at an actual Starlink user terminal, the location had to be for that terminal too, and they were able to get it within 30 meters. Not better than GPS, obviously, but it could be quicker and eventually more accurate if SpaceX were to give the project its blessing.

A software update that slightly adjusts how the satellites send their signals and a bit of data on correcting for variance between their clocks, and Humphreys suggests Starlink transmissions could be used to locate oneself to within a meter.

You can read the paper here [pdf].

It seems a no-brainer that at some point SpaceX management will recognize the money they can make from this extra capability, and will figure out the best way to produce and sell handheld units. It also appears that there will be profit in allowing others to also tag on.

Virgin Orbit gets UK marine license for its Cornwall launch

9:26 am

Virgin Orbit has been issued its marine license from the United Kingdom for its planned October 29, 2022 launch from Cornwall, the first such orbital launch from the British Isles.

Virgin Orbit proposes to conduct a maximum of one launch in 2022 and approximately two launches per year over the next 8 years (January 2023-December 2030).

The licence issued by MMO covers the 2022 launch, the first of its kind in the UK. As there is material to be deposited into the sea that will be loaded in the UK, the activity requires a marine licence from MMO, as required by The Marine and Coastal Access Act 2009.

The ever-growing reach of government bureaucracy is worldwide. Though Virgin Orbit’s airplane, carrying the LauncherOne rocket and its seven smallsats, is taking off from Cornwall, the release of that rocket will not occur until it is over the Atlantic, with the expendable first stage falling into the ocean west of Portugal. Yet somehow the company must get permission of these UK bureaucrats — as well as American ones — to fly.

  • China schedules December 3rd orbital launch of rocket fueled by oxygen-methane

    • The other methane-fueled rocket engines come from SpaceX (on Starship/Superheavy) and Blue Origin. ULA was supposed to have launched with Blue Origin’s BE-4 engine two years ago. The launch won’t happen before 2023. SpaceX’s first Starship orbital attempt could happen any time before the end of the year.

    This Chinese rocket could thus be the first methane-fueled rocket to reach orbit.

Who and What to vote for in Arizona in 2022

12:01 pm

Liberty enlightening the world
The citizen is sovereign, and your vote demonstrates that power

I first posted my election choices in Arizona on October 11, 2022, the day before the start of early mail-in voting in this state. However, I am now posting my choices again because there were two propositions (#128 and #130) then that I was unsure about how I wished to vote. I have now done a bit more research, and made my choices. I think my analysis will be useful to my readers.

I have also included more information about the candidates running.

I want to once again emphasize that though I am not partisan, based on the steady decline of thought in the Democratic Party combined with its increased passion for arresting and violently harassing its opposition, I cannot at present vote for anyone in that party. I wish this was not the case, but I also believe strongly that if American voters throw out as many Democrats as possible in November, it will allow for that party to reform itself. With the defeat of its present leadership, the party will be faced with a stark choice: find new leaders, shift gears, or die (allowing a new party to replace it). With any of these options, the voters would be provided with a new choice in future elections, coming from a different direction.

As a perfect example of the mindless corruption that has now taken over the Democratic Party, witness President Joe Biden’s statement this past weekend throwing his full support behind the castration and mutilation of children in order to change their sex, as advocated by the “trans” movement — which in plain English is a movement of cross-dressers demanding more power over everyone else.

The president denounced Republican states that have passed laws attempting to ban or limit sex change surgeries and transition treatments – like hormone blockers – for children who identify as non binary or transgender. Biden spoke with a panel of six progressive activists for the NowThis News presidential forum on Friday, which aired on Sunday. One of the six panelists was TikTok star Dylan Mulvaney who is documenting their transition from a male to trans woman.

When asked if red states should have the right to pass laws limiting access to gender-affirming treatments, Biden said: ‘I don’t think any state or anybody should have the right to do that.’

‘As a moral question and as a legal question, I just think it’s wrong,’ the president added.

This corruption in the Democratic Party has also made the Republican Party unreliable, which is why the Republican slate in Arizona is so important. All of the state’s major candidates (governor, senate, secretary of state, attorney general) are not from the established party. They are mostly Trump outsiders, who are running on platforms calling for major reform. Giving them all a win will send shockwaves throughout the political landscape, on both sides of the political aisle. The establishment controlling both parties might finally realize they must pay attention to the citizens of the country, not their own wishes.

All these factors suggest that this is a truly significant election. or as Doug Ross noted in this excellent essay:

This is our generation’s fork in the road and the stakes of our decision could not be higher. If we are to protect our society from the inevitable decline and despotism that has infected so many societies since the beginning of time, in whom should we trust? If we are to shield our children from the tyranny against which our founders fought and so many Americans shed blood, in whom should we put our faith?

I contend that we must fight the anti-Constitutional counter-revolution using every political tool at our disposal. We must pledge to return our country to the rule of law, as it was originally defined by our founders and codified in the Constitution. For anything less condemns our descendants to the fate that Thucydides described. The choice is clear. The question is simple.

Which road will you choose?

Thus, below are my updated final election choices. Note too that I have not contributed any money to any of these candidates, nor have I received any money from any candidate or party as well. These opinions are solely my own.

A hole in space

A hole in space
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and was released today as its picture of the week. From the caption:

This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion. NGC 1999 is around 1350 light-years from Earth and lies near to the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation — it is composed of detritus left over from the formation of a newborn star.

Just like fog curling around a street lamp, reflection nebulae like NGC 1999 only shine because of the light from an embedded source. In the case of NGC 1999, this source is the aforementioned newborn star V380 Orionis which is visible at the centre of this image. The most notable aspect of NGC 1999’s appearance, however, is the conspicuous hole in its centre, which resembles an inky-black keyhole of cosmic proportions.

Once astronomers thought the black area was caused by dust, blocking the light. Now, based on a lot of new data from multiple ground- and space-based telescopes, they know that it actually is a black empty void. Why it exists however is not yet understood.

Spanish high altitude tourist balloon company prepares for first test flight

9:07 pm

The Spanish high altitude tourist balloon company HALO is preparing to do the first test flight in December from India, with the second test flight planned for the first quarter of 2023 from Spain.

The Madrid-based company will take tourists to the edge of space in a capsule attached to a balloon – with prices from £87,000 to £174,000 (100,000 to 200,000 Euros).

The final capsule design will have capacity for 8 passengers and a pilot and feature panoramic windows which allow 360-degree views of the Earth at an altitude of up to 25 miles.

…The first commercial flights are expected to start in 2025 and the company plans to operate in four continents, making a total of 400 commercial trips with 3,000 passengers per year from 2029.

This market now appears to have three companies vying for customers, the American companies World View and Space Perspectives, and this Spanish company.

OneWeb paid ISRO about $130 million for two GSLV launches

8:56 pm

It appears that OneWeb agreed to pay India’s space agency ISRO about $130 million for two GSLV launches, putting up 36 satellites on each launch.

When asked how much his business would spend to have 72 satellites launched, OneWeb Chairman Sunil Bharti Mittal told reporters in India that it would be more than Rs 1,000 crore.

Rs 1,000 crore translates to about $130 million, which means OneWeb paid about $65 million per launch, which is comparable to SpaceX’s standard Falcon 9 price, before discounts for using previously launched boosters.

It also appears that at present this deal is the only one between ISRO and OneWeb, and that the remaining 576 satellites that OneWeb needs to launch to complete its constellation are still open for others. At present, SpaceX and Relativity have contracts, though it is unclear how many each will launch. I suspect SpaceX will be the majority, since Relativity has not even completed its first test launch. It is also possible that ISRO will get more contracts based on its first launch success.

Russia launches 4 satellites with Soyuz-2 rocket from Vostochny

8:06 am

Russia yesterday successfully launched four satellites from its Vostochny spaceport, using its Soyuz-2 rocket.

Three satellites were part of Russia’s data relay satellite constellation, and one was the first test satellite of Russia’s proposed low Earth orbit broadband constellation, comparable to Starlink.

The leaders in the 2022 launch race:

48 SpaceX
45 China
17 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 68 to 45 in the national rankings, but trails the world combined 71 to 68.

India’s GSLV-Mark3 rocket launches 36 OneWeb satellites

11:58 am

India’s GSLV-Mark3 rocket, its most powerful, has successfully placed 36 OneWeb satellites into orbit. As of this writing, the first 16 of the 36 satellites had successfully deployed.

This was the first international commercial launch for the GSLV rocket, previously used exclusively for Indian launches. It was also the first launch of OneWeb satellites since its deal with Russia was broken off due to the Ukraine war. Though the company had also quickly signed SpaceX to resume launches, I suspect that since half of OneWeb is owned by a major Indian investment company, India was given favored treatment in determining who would launch first.

This was the third successful launch in 2022 for India, the most since that country shut down in 2020 due to its panic over the Wuhan flu.

The leaders in the 2022 launch race remains unchanged:

48 SpaceX
45 China
16 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 68 to 45, though it now trails the world combined 70 to 68.

NASA buys 3 Orion capsules from Lockheed Martin for $2 billion

10:02 am

Nice work if you can get it! Earlier this week NASA awarded Lockheed Martin a new contract worth $1.99 billion to build three more Orion capsules for its Artemis program.

This order marks the second three missions under the agency’s Orion Production and Operations Contract (OPOC), an indefinite-delivery, indefinite-quantity (IDIQ) contract for up to 12 vehicles. A breakout of these orders includes:

  • 2019: NASA initiates OPOC IDIQ and orders three Orion spacecraft for Artemis missions III-V.
  • 2022: NASA orders three additional Orion spacecraft missions for Artemis VI-VIII for $1.99 billion.
  • In the future: NASA can order an additional six Orion missions.

Under OPOC, Lockheed Martin and NASA have reduced the costs on Orion by 50% per vehicle on Artemis III through Artemis V, compared to vehicles built during the design and development phase. The vehicles built for Artemis VI, VII and VIII will see an additional 30% cost reduction.

Lawdy me! They’ve reduced the price! Lockheed Martin is only charging NASA three-quarters of a billion dollars per capsule on this new contract (after NASA spent about $18 billion for the development of the first six capsules– that’s $3 billion each). And Lockheed Martin will only charge about a half billion per capsule for future capsules! My heart be still.

Meanwhile, SpaceX is designing, testing, building, and will likely launch its reusable Starship manned spacecraft, which could launch about 10 Orion capsules on each launch, for about $10 billion total. Once flying the expected cost per launch will likely be much less than $100 million, with SpaceX claiming it could be as low as $2 million. Even if you add the development cost for these launches, Starship will cost less than Orion by many magnitudes, on its first launch.

I wonder, which is the better bargain? NASA clearly can’t figure it out, and NASA has the smartest, most brilliant people in the universe working for it.

ESA asks member nations to build lander for Franklin Mars rover

9:47 am

In its most recent request for funding from the member nations of the European Space Agency (ESA), the agency has asked the member nations to finance the design and construction of a new lander for its long delayed Rosalind Franklin Mars rover, replacing the Russian lander that had became unavailable due to sanctions resulting from Russia’s invasion of the Ukraine.

According to the BBC (opens in new tab), ESA will request 360 million euros to kickstart work on the new landing system, with additional funds likely needed in subsequent years. ESA has already spent some 1.3 billion euro on the ExoMars program, which also includes an orbiter that has been studying Mars’ atmosphere and surface since 2017. ESA will put the plan in front of delegates of its 22 member states at a ministerial conference in November.

“We will have to wait if the [member states] decide to go forward with the project,” Parker said. “This concept is now proposed as part of the director general’s package within [ESA’s] exploration program for decision at the ministerial [conference].”

If ESA’s member nations agree to this plan, expect the launch of Franklyn to be delayed further. Based on the normal pace in which ESA functions, that lander will take a minimum of five years to design and build (likely much longer). Though ESA is now targeting ’28 for the launch of Franklin, which was supposed to launch this past summer after a two year delay, this plan likely means it will not get off the ground this decade.

Meanwhile, there are now at least a half dozen private companies building lunar landers that could more quickly (and for less money) get a Franklin Mars lander built for ESA. None are in Europe however, which means ESA would rather have this mission delayed years so that it can funnel money to its own contractors..

Russia’s Soyuz-2 rocket launches two military satellites

9:37 am

Russia today successfully launched from its Plesetsk spaceport two military satellites using its Soyuz-2 rocket.

Russian sources provided little information but it appears the launch was timed to allow these satellites to come close to an American military satellite.

Today’s launch of Kosmos-2561 and 2562 also seemed to mirror the trajectory of USA-326, with the American satellite passing over the cosmodrome roughly at the time of today’s launch.

If the latest launch is an inspector mission, it is possible that Kosmos-2562 is a subsatellite that was released by 2561 shortly after launch, as previous inspector satellites have done. Kosmos-2542 was believed to have been an inspector satellite, although never confirmed by Russia, and later released Kosmos-2543.

The launch was from the interior of Russia. The Soyuz-2 version launched was one with no side boosters, so that only the expendable core stage crashed in Russia.

The leaders in the 2022 launch race:

48 SpaceX
45 China
16 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 68 to 45, though it now trails the world combined 69 to 68.

The launch of 36 OneWeb satellites by the biggest version of India’s GSLV rocket is right now counting down for a launch shortly. You can watch it here.

Bedrock layers in Terby Crater on Mars

Bedrock layers in Terby Crater on Mars
Click for full image.

Cool image to end the week! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken by on July 18, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the bedrock layers on one of two very large mesas that jut out into the floor of 108-mile-wide Terby Crater.

I want to focus your eye on the spoon-shaped mesa near the top right of the photo. Note how the layers can be seen on both sides, even though the top of the mesa seems to be concave. This is strange and complex geology, made even more fascinating in that the two mesas almost reach the center of the crater floor. Why are they here? Why were they not flattened during impact, like the rest of the crater floor? Or maybe the original crater floor is the mesa top, but if so, why did the rest of the crater interior get eroded away.

The overview map below provides some context, and helps fill in some details, even if it fails to answer any of these questions.

Teachers fired and blacklisted for opposing the queer agenda in childcare and elementary schools

1:01 pm

As I did yesterday, today’s blacklisting column will cover a number of individual stories, this time focusing on the blacklisting of teachers who oppose indoctrinating very young children to the queer agenda. I am reporting more than one story in order to make sure these stories do not fall by the wayside. The harm done to the individuals does not go away, even if the news cycle considers their story stale.

Bright Horizons commitment to Critical Race Theory and the queer agenda, for toddlers
Screen capture from Bright Horizons’ own webpage.
Very clearly, Bright Horizons is determined to teach
Critical Race Theory and the queer agenda to toddlers.

First we have California teacher Nelli Parisenkova, who was fired from her job with the nationwide childcare company Bright Horizons because she for religious reasons refused to read books promoting the queer agenda to 1 to 5-year-old toddlers.

What makes this story especially egregious is the vindictive manner in which Parisenkova was treated. From the lawsuit [pdf]:

The childcare room at Bright Horizons where Ms. Parisenkova works has children’s books on the shelf that promote and celebrate same-sex relationships and marriage. When Ms. Parisenkova first started working for Bright Horizons, her supervisor at the time provided her with an informal accommodation that she would not be required to read books to the children promoting same-sex marriage. However, on or around April 7, 2022, Katy Callas, the director of the location where Ms. Parisenkova worked, discovered Ms. Parisenkova’s religious beliefs in this regard. Ms. Callas, who is lesbian, apparently took personal offense at Ms. Parisenkova’s religious beliefs.

Ukraine officials in direct negotiations with Musk about Starlink

10:22 am

According to the Ukraine’s defense minister, they are now conducting direct negotiations with Elon Musk concerning the cost of using SpaceX’s Starlink constellation as part of its war against Russia.

In an interview, Defense Minister Oleksii Reznikov said “I know that we will not have a problem” keeping the service active, citing the “personal communication” between Ukraine’s Minister of Digital Transformation Mykhailo Fedorov and Musk.

Fedorov “is responsible for the digitalization and he has a direct connection with Elon Musk. They have a personal communication, and Mykhailo was really positive” about the situation in their last discussion of the issue, Reznikov said.

I suspect that at some point, the Ukraine will start paying SpaceX some money out of the $20 million per month Musk says it costs. And it will likely draw the cash for those payments from the approximately $50 billion the U.S. has sent it in aid.

Astronomers discover an exoplanet with the density of a marshmallow

10:18 am

Using ground-based telescopes to gather more data about an exoplanet discovered by the orbiting TESS telescope, astronomers have found that it has the density of a marshmallow.

The planet orbits a red dwarf star, the most common star in the universe, and is the “fluffiest” yet seen around this type of star.

Red dwarf stars are the smallest and dimmest members of so-called main-sequence stars — stars that convert hydrogen into helium in their cores at a steady rate. Though “cool” compared to stars like our Sun, red dwarf stars can be extremely active and erupt with powerful flares capable of stripping a planet of its atmosphere, making this star system a seemingly inhospitable location to form such a gossamer planet.

Astronomers remain puzzled how such a large fluffy planet could have formed around such a dim small star.

Rate of micrometeorite impacts on Webb holding as expected

10:10 am

According to this Space.com article, the rate and size of micrometeorite impacts on the main mirror of the Webb Space Telescope has held steady at the rate and size expected, since the first surprisingly large micrometeorite impact in May that slightly dinged one mirror segment.

At this point, JWST has experienced a total of 33 micrometeoroid events, according to Smith’s slides. But the most damaging one came before JWST began science observations; in late May, a particularly large micrometeoroid struck the observatory’s mirror, leaving its mark on one golden hexagon. The team estimates that a strike of that size should occur about once a year, Smith said.

“So we got that at month five,” he said. “We haven’t seen another one yet, so it’s still consistent with the statistics that we expected.”

Smith noted that, at the current impact rate, Webb will still be meeting its five-year performance requirement 10 years into the mission. Scientists estimate that the observatory has enough fuel to operate for 20 years.

Meanwhile, one of Webb’s infrared cameras is not doing spectroscopy as engineers analyze the high levels of friction in a “grating wheel.” At this point it appears they still do not understand the cause of the friction, and thus have not come up with a plan for mitigating it.

Chandrayaan-3 now scheduled for summer 2023

10:01 am

India’s second attempt to put a rover on the surface of the Moon, Chandrayaan-3, has now been tentatively scheduled for launch in the summer of 2023.

The launch had originally been scheduled for launch in the fall of 2020, but was delayed when India shut down due to the Wuhan panic. Official at ISRO, India’s space agency, had hoped to launch by the summer of 2022, but that proved impossible. They have now delayed the mission a full year.

In fact, all earlier reports had indicated the rover was almost ready. This new delay of a full year suggests that some new issues might have been identified.

The news article at the link also notes that ISRO is now planning two unmanned orbital missions plus four launch abort tests before launching its first manned mission, dubbed Gaganyaan, not two abort tests as previously planned. They are still targeting ’24 for the manned mission.

InSight status: Barely hanging on

9:50 am

InSight's power status as of October 19, 2022

The science team for the InSight lander on Mars today posted an update on the power the spacecraft’s dust covered solar panels are producing. I have added that data to my on-going graph of these power levels, to the right. From the update:

On October 19, 2022, InSight was generating an average between 275 and 285 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at 1.5 (typical tau levels outside of dust season range from 0.6-0.7).

The jump in tau level is due to a large dust storm that developed in September more than two thousand miles away in the southern hemisphere. Though it is so far away, that storm put a lot more dust in the atmosphere above InSight, and forced engineers to shut down all but its most essential functions.

That storm is apparently continuing, and might even be growing. If so, the future of InSight is dim indeed. Any further drop in the amount of power it generates daily will likely make it unable to operate at all, and the mission will end.

Frozen lava flows around Martian hills

Martian lava flowing around hills
Click for full image.

Cool image time! The photo to the right, rotated, cropped, reduced, and enhanced to post here, was taken on August 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the westernmost edge of the Athabasca flood lava plain, thought to be the youngest lava flow on Mars, having covered the area of Great Britain in a matter of weeks 600 million years ago.

This image was a captioned feature yesterday by the MRO science team. As they note:

Although you can’t sail a boat on a sea of lava, hills and craters that stick up higher than the lava flow act like barriers. When a boat is driven through the water, there is a bow wave at the front of the boat, and a wake that trails off behind that indicates which way the boat is moving. In a lava flow, when a hill sticks up, the lava piles up on the upstream side (just like a bow wave) and can leave a wake on the downstream side, so we can tell which way the lava was moving against the stationary hill.

As you can see, every hill has a pile of lava on its northeast slopes, and a wake to its southeast. As the main vent of the Athabasca eruption is to the northeast, about 500 miles away (as shown on the overview map below), the flow direction suggested by the wakes fit the general geography.

  • Chinese scientists produce a tectonic map of the Moon

    • Their paper is here. From the abstract:

    The map provides a state-of-the-art illustration of structures and tectonic units of different periods, the distributions of 9 types of linear structures, including 18976 elements (358 inferred deep faults, 1335 shallow faults, 11046 wrinkle ridges, 474 rillles, 816 grabens, 2583 crater-floor fractures, 227 lobate scarps, 1882 impact fractures and 255 impact crater chains), and 5 types of circular structures, including 2501 elements (271 volcanic vents, 47 domes, 46 mascons, 3460 impact craters and 81 impact basins).
