SpaceX successfully launches communications satellite for Eutelsat

8:06 pm

SpaceX tonight successfully launched a geosynchronous communications satellite for Eutelsat. This was the third launch that SpaceX has done for this European company, which previously had traditionally been launched by Arianespace. Because of the delays and higher cost to use Arianespace’s new Ariane 6 rocket, the company chose to go with SpaceX instead.

The first stage, which had flown ten times previously, successfully completed its eleventh flight, but was not recovered because all of its fuel was needed to get the satellite to its proper orbit.

The leaders in the 2022 launch race:

53 SpaceX
52 China
19 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 77 to 52 in the national rankings, but trails the rest of the world combined 80 to 77.

Dick Cavett – Burt Lancaster in the circus

6:01 pm

An evening pause: This interview of Burt Lancaster on the Dick Cavett Show took place on July 21, 1969 (the day after Neil Armstrong took that first step on the Moon).

I could not help noting how humble and gracious Lancaster seemed. He might have been one of the world’s most charismatic actors, but he surely did not appear full of himself. The second part of this interview can be watched here.

Hat tip Cotour.

Pushback: Court rules against college’s attempt to censor students

1:33 pm

One poster that Clovis Community College tried to censor
One of the posters that Clovis Community College officials agreed to
“gladly” remove because it made some students “very uncomfortable.”

Bring a gun to a knife fight: A federal judge has issued a preliminary injunction against Clovis Community College in California, ruling that it violated the free speech rights of its students when college officials removed posters put up by students from the college’s Young Americans for Freedom chapter that condemned communism and socialism.

The lawsuit [pdf] was filed for the students by the Foundation for Individual Rights and Expression (FIRE).

The college insists that it reserves the right to remove flyers over “inappropriate or [offensive] language or themes.” The lack of any definition for those vague terms would weigh heavily with the court in granting the preliminary injunction.

FIRE produced emails showing that a college administrator offered to “gladly take down” the flyers after “several people” said that they were “very uncomfortable” with the flyers, including a person who allegedly threatened a “harassment claim” if the posters were not taken down.

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.

Curiosity’s wheels: Maybe not so bad after all

11:09 am

Comparison of one wheel on Curiosity
To see the original images, go here and here.

Today the science team for the Mars rover Curiosity downloaded more photos of its wheels, a survey taken routinely now after every 500 meters or 1640 feet of travel. Unlike the pictures made available yesterday that showed some of the worst damage to one of Curiosity’s middle wheels, these new images included the wheel I have been tracking since 2017 as a baseline to see if further damage has occurred.

The photos to the right show that wheel, with the top photo from August and the bottom created from two pictures taken on November 20, 2022. The numbers indicate the matching treads. The “+” sign in the top image indicates a location where new damage was spotted in August.

As you can see, this wheel does not appear to have experienced any additional damage in the more than three months since that August update. While the damage to Curiosity’s wheels remains very concerning, it does appear based on this one wheel that — despite the generally very rough terrain the rover has been traversing since it entered the foothills of Mount Sharp — the wheels in general seem to be holding up.

Though I have not done a careful comparison of these new wheel images with earlier ones, none of the new images appear to show any additional significant damage. It appears that the travel criteria the science team adopted years ago — right after discovering the wheel damage — continues to work to protect the wheels. It picks the rover’s path more carefully to avoid sharper rocks, and includes software that stops the rover should it sense it is crossing a rock sharper than desired.

Six of the ten cubesats launched toward the Moon by SLS still working

9:46 am

The Moon as seen by ArgoMoon
Click for full image.

Of the ten cubesats launched toward the Moon by SLS last week, six are still working while four have problems that are likely killing their missions.

The photo to the right, cropped, reduced, and sharpened to post here, was taken by ArgoMoon, an Italian cubesat that is working perfectly. The large impact basin visible is Orientale Basin, located just on the edge of the visible face of the Moon but partly hidden on the far side.

A summary of the status of all ten can be found here. Of the other five still functioning properly, all have been able to maintain proper communications.

Possibly the biggest disappointment however is the failure of Japan’s Omotenashi lander, which was going to attempt a lunar soft landing. Shortly after launch it began tumbling, and engineers were never able to regain full control or communications. The landing attempt has now been abandoned.

Side note: Orion itself also captured some images as it zipped past the Moon yesterday, but they do not appear as high quality as ArgoMoon’s pictures.

Astronomers spot asteroid mere hours before it burned up in Earth’s atmosphere

9:29 am

For only the sixth time, astronomers this past weekend were able to image an asteroid just before it hit the Earth’s atmosphere and burned up over Canada.

The mini-asteroid, less than 3 feet (1 meter) wide, was spotted by astronomer David Rankin at Mount Lemmon Observatory in Arizona, according to SpaceWeather.com. Subsequent observations by other astronomers confirmed that the rock, coming from the direction of the main asteroid belt between the orbits of Mars and Jupiter, was on a collision course with Earth.

Only three hours after the first detection, the object, since dubbed C8FF042, sliced through the sky above Canada and landed in Lake Ontario, according to NASA.

While it is believed that most of the meteorite’s pieces that reached the ground fell into Lake Ontario, there is a chance some pieces might still be found along the south coast of the lake between Hamiliton and Niagara Falls.

CAPSTONE enters its planned lunar orbit

9:21 am

After experiencing serious tumbling shortly after launch, engineers have successfully put the technology test smallsat CAPSTONE into its planned lunar orbit (the same to be used by NASA’s Lunar Gateway space station), where it will spend at least six months gathering data.

In addition to studying this unique orbit, CAPSTONE’s mission also includes two technology demonstrations that could be used by future spacecraft. The Cislunar Autonomous Positioning System, or CAPS, is a navigational software developed by Advanced Space that would allow spacecraft operating near the Moon to determine their position in space without relying exclusively on tracking from Earth. CAPSTONE will demonstrate this technology by communicating directly with NASA’s Lunar Reconnaissance Orbiter, which has been in orbit around the Moon since 2009. CAPSTONE will also demonstrate one-way ranging using a chip-scale atomic clock, which could allow spacecraft to determine their position in space without the need for a dedicated downlink to ground stations.

CAPSTONE is also demonstrating a third technology as well as the use of capitalism in space. The third technology is demonstrating the viability of using a tiny inexpensive smallsat for these kinds of interplanetary missions. The capitalism is that CAPSTONE was built by a private company, Terran Orbital, not NASA, and is being operated by another private company, Advanced Space, not NASA. It was also launched by a private company, Rocket Lab, not NASA. All three have proved or are proving that it is faster and cheaper for the government to merely act as the customer to private enterprise, rather than being the builder/operator and boss.

ABL’s RS1 rocket has another abort at launch

9:10 am

In making its third attempt to launch its first RS1 rocket, ABL engineers experienced their second abort at T-0, with the rocket shutting down just as its engines ignited.

The first attempt on Monday, Nov. 14, was scrubbed due to off-nominal data on the first stage during propellant loading. A second attempt on Thursday, Nov. 17, was aborted due to turbopump oxygen inlet conditions at engine ignition. The most recent attempt on Monday, Nov. 21, was aborted during engine ignition at T-1.75 seconds.

The company is now targeting December 7th for their fourth launch attempt. The rocket carries two customer cubesats, but its main mission is to demonstrate its ability to reach orbit.

InSight still alive

3:27 pm

InSight's power levels

The InSight science team today posted another update on the power status of the Mars lander, as shown in the graph to the right.

As of Nov. 21, 2022, InSight is generating an average between 300 and 310 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at 1.33 (typical tau levels outside of dust season range from 0.6-0.7).

Power levels, while critically low, remained level and sufficient to run the seismometer, though nothing else. At the beginning of the month the science team said these levels would only allow operations for a few more weeks, but here we are, a few weeks later, and InSight is still alive, though barely.

At this moment the situation is essentially day-to-day. If the lander misses two scheduled communications sessions, they will declare it dead. So far, that has not happened.

New serious damage to Curiosity’s wheels?

11:07 am

New damage to Curiosity's wheels?
Click for original image.

I must start this post with a strong caveat. The serious damage, as posted to the right, of the zig-zag growser treads on one of Curiosity’s wheels that was photographed by one of the rover’s cameras yesterday and downloaded today, could very well not be new damage. As noted in a report in June:

The team discovered that the left middle wheel had damaged one of its grousers, the zig-zagging treads along Curiosity’s wheels. This particular wheel already had four broken grousers, so now five of its 19 grousers are broken.

The damaged wheel to the right appears to be that left middle wheel. This photo thus might simply be documenting the damage noted in June, and not new damage. Since Curiosity has six wheels (three on each side), the middle wheels like this one are likely slightly less critical and can be worked around should it no longer function well.

Nonetheless, the damage to these growsers is of concern. Previously, the wheel damage has consistently involved breakage in the metal plates between the growsers. Though the science team noted in that June report that it has “proven through ground testing that we can safely drive on the wheel rims if necessary”, the team also said that it did not think that was going to happen soon.

Based on this image, however, it is happening, at least on one wheel. Fortunately, a review of all the images downloaded yesterday does not show any other broken growsers on any other wheel, though the image survey is not thorough and does not cover the entire surface of every wheel. For example, I could not identify any images of the damaged sections of the wheel that I have been tracking since 2017. It could be that the photo’s orientation this time was significantly different, making it difficult to find a match. It could also be that the damage had increased so much that no match with an earlier photo was easily possible. Or it could simply be that the same section on the wheel was not photographed this time.

Either way, the damage on this middle wheel foreshadows the rover’s eventual future, a future that is likely getting closer because of the roughness of the mountain and rocky terrain that Curiosity is presently traveling, and appears to have no end as it now climbs Mount Sharp.

Smeared colliding galaxies

9:29 am

Smeared colliding galaxies
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 as part of its continuing program to collect images of unusual galaxies that had previously not been observed at high resolution.

The Arp-Madore catalogue is a collection of particularly peculiar galaxies spread throughout the southern sky, and includes a collection of subtly interacting galaxies as well as more spectacular colliding galaxies. Arp-Madore 417-391, which lies around 670 million light-years away in the constellation Eridanus in the southern celestial hemisphere, is one such galactic collision. The two galaxies have been distorted by gravity and twisted into a colossal ring, leaving the cores of the two galaxies nestled side by side.

It is likely that this collision has been going on for many millions of years, and will not be over for many millions of years to come. In the end the two galaxies will likely merge into one whose final shape cannot be predicted.

Orion successfully enters its preliminary lunar orbit

8:54 am

NASA’s Orion capsule today successfully completed a 2.5 minute engine burn this morning to put it in its preliminary lunar orbit around the Moon.

At the time of the burn, Orion was 328 miles above the Moon, travelling at 5,023 mph. Shortly after the burn, Orion passed 81 miles above the Moon, travelling at 5,102 mph. At the time of the lunar flyby, Orion was more than 230,000 miles from Earth.

The outbound powered flyby burn is the first of two maneuvers required to enter the distant retrograde orbit around the Moon. The spacecraft will perform the distant retrograde orbit insertion burn Friday, Nov. 25, using the European Service Module. Orion will remain in this orbit for about a week to test spacecraft systems.

NASA has been bragging that when this orbit sends Orion 40,000 miles past the Moon, it will be the farthest a man-rated spacecraft has flown from Earth since Apollo. Though true, this fact is somewhat trivial. First, SpaceX could have easily put a Dragon capsule on its first Falcon Heavy launch, instead of a Tesla, and sent that capsule into interplanetary space beyond Mars. Second, Orion is not capable of taking any astronauts farther than lunar orbit. Thus, NASA’s achievement here is somewhat overblown. Orion is not an interplanetary spaceship. It remains nothing more than an overpriced, overweight, and over-designed ascent-descent manned capsule.

Chinese seize space debris being towed by Filippino sailors

8:44 am

According to Filippino Navy officials, after their sailors had captured and was towing a piece of space floating rocket debris back to shore, the Chinese Coast Guard arrived and forcibly seized it, cutting the tow line.

As they were traveling back to the island, “they noticed that a China coast guard vessel with bow number 5203 was approaching their location and subsequently blocked their pre-plotted course twice,” Carlos said in a statement.

The Chinese coast guard vessel then deployed an inflatable boat with personnel who “forcefully retrieved said floating object by cutting the towing line” attached to the Filipino sailors’ rubber boat. The sailors decided to return to their island, Carlos said, without detailing what happened.

Chinese officials denied this, saying they took possession after a “friendly consultation.”

Whether or not the Chinese took this debris by force or not, the fact remains that it existed, indicating once again that China is dropping rocket parts indiscriminately on other nations. In this case the debris probably came from either a first stage or a strap-on booster, released shortly after the launch from a low enough altitude that it doesn’t burn up in the atmosphere.

Lucy engineers again attempt to complete deployment of solar array

12:01 am

Lucy solar panel graphic
Artist’s impression of solar panel

On November 7, 2022, the Lucy science team made another attempt to complete the deployment of one of the spacecraft’s two solar arrays, as shown in the graphic to the right. After launch that array failed to deploy properly, and though later attempts have gotten it mostly open, it has not latched tight.

On Monday, Nov. 7, the spacecraft was instructed to point toward the Sun and operate the array deployment motors for a short period of time. As expected, the latest attempt deployed the wing incrementally forward, but it did not latch. The operation did succeed in providing the team with data to evaluate the array’s status and ascertain any changes since the last deployment attempt on June 16.

During this analysis, the team identified that a small vibration occurred as the unlatched array interacted with the spacecraft’s attitude controller while the array was pointed toward Earth and at a cold temperature. The vibration did not occur as a result of the deployment activity itself. While this vibration is too small to pose a risk to the spacecraft in its current state, further array deployment attempts have been paused while the attitude controller is updated to resolve this issue. In the meantime, the spacecraft was reoriented so that the array is warmer, and the team found that the vibration is not present. The team will re-evaluate further redeployment activities once the updates to the controller are checked out on the spacecraft.

In other words, engineers have decided to halt further deployment attempts until they understand fully the cause of this vibration.

At present, the spacecraft is in good health, and the array, only a few degrees short of full deployment, is producing more than 90% of its expected power, more than enough to run the full mission.

  • NASA declares inflatable heat shield test flown on Atlas-5 launch a success

    • And as the agency does so often, it now shuts things down, having no plans to fly it again. It could be scaled up for future Mars missions, but no such mission is presently planned. ULA, which partnered with NASA on the test, is likely to take this technology and use it to recover the 1st stage engines on Vulcan.

Pushback: Court orders school board to stop censoring and banning parents

1:26 pm

The Forsyth County School Board

Bring a gun to a knife fight: In a victory for free speech, a federal judge has ruled that the censorship and banning of some parents by the Forsyth County Board of Education in Georgia was unconstitutional, and must cease immediately.

This is a follow-up of a previous blacklist story from back in August, when those parents sued the board because it would not permit them to speak at board meetings during public comment about the pornography the board was allowing in schools.

Multiple district residents, including Mama Bears members and plaintiffs in the lawsuit Alison Hair and Cindy Martin, have used their time to read aloud from school library books they consider pornographic. Yet while these materials are available to kids in school, the Chair has cut off and banned speakers who read from them at Board meetings when he deems the language inappropriate or profane.

Colliding glaciers

12:19 pm

Overview map

Colliding glaciers

For today’s cool image we return once again to glacier country in the northern mid-latitudes of Mars. The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on August 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a spot where I think glacial flows coming from the north and south have collided at a low point. The white dot in the box on the overview map above marks its location, with the inset showing the mesas to the north and south that suggest this flow pattern.

What makes these colliding flows especially cool is the source of the northern flow. It appears that came out of the impact heat from that crater, which caused the ice on the downhill side to flow. You can also see the same phenomenon a short distance to the east, with a much smaller crater, likely a secondary impact from the first.

Note also the glacial fill inside the larger crater. This impact happened on top of older glaciers, but later climate cycles caused more ice to be deposited within the crater afterward. That this glacial fill appears terraced and thus layered also suggests that there were several if not many such later climate cycles.

LightSail-2 completes three-plus year mission, burning up in atmosphere

9:44 am

LightSail-2 sail deployed
LightSail-2, shortly after deployment in 2019.

LightSail-2, an experimental solar sail built by the Planetary Society, finally ended its mission this week, with the test sail burning up in the atmosphere upon re-entry.

LightSail 2 was launched aboard a SpaceX Falcon Heavy rocket in June 2019, settling into an initial orbit at an altitude of around 720 km (450 miles). At that height, the Earth’s atmosphere is still thick enough to create drag, which would threaten to eventually pull the spacecraft down.

But that’s where the plucky little satellite’s special ability came in. Although it’s only the size of a shoebox, LightSail 2 unfurled a big reflective sheet, called a solar sail, about the size of a boxing ring. The idea is that photons from sunlight strike this sail and generate tiny amounts of thrust, allowing the craft to change its orbit.

And LightSail 2 demonstrated this concept beautifully. In three and a half years, the spacecraft completed around 18,000 orbits and traveled 8 million km (5 million miles), adjusting its orbit continuously to keep itself aloft. But all good things must come to an end, and sometime on November 17, drag finally won the tug-of-war and pulled the spacecraft back to Earth.

LightSail-2 was the third time a light sail had been flown in space, with the first, Ikaros, deployed by the Japanese in 2010 and flown in solar orbit through 2012. That mission was successful in using sunlight to accelerate the sail. This was followed by LightSail-1 in 2015. That mission has some communications problems, but eventually succeeded in its main engineering mission by testing the sail deployment system.

Boeing announces major reorganization

9:33 am

Boeing yesterday announced that it is doing a major reorganization of its defense, space, and security divisions.

The action will replace numerous executives while reducing eight different divisions into four.

Such action was long overdue, considering Boeing’s many recent engineering failures, from space (Starliner) to aviation (737-Max), all of which demanded such a reorganization and consolidation, simply to pay the bills if not to fix serious management shortcomings. The bad economy has only made this more urgent.

Japan to stay on ISS to 2030 in exchange for an astronaut flight to Gateway

9:26 am

NASA yesterday announced that Japan has agreed to remain on ISS through 2030, the first international partner to do so, and in exchange will get a Japanese astronaut flight to the Lunar Gateway station.

Under the Gateway Implementing Arrangement, NASA will provide an opportunity for a Japan Aerospace Exploration Agency (JAXA) astronaut to serve as a Gateway crew member on a future Artemis mission. This formally represents the first commitment by the U.S. to fly a Japanese astronaut beyond low-Earth orbit aboard NASA’s Space Launch System (SLS) rocket and Orion spacecraft.

I remain very doubtful in the long run these flights will occur on SLS, which simply cannot launch frequently enough to make the entire program viable. More likely with time the rocket will be replaced by other commercial carriers.

SpaceX cancels launch after reviewing static fire test data

9:06 am

After a review of the test data produced during its standard dress rehearsal countdown and static fire prior to launch, SpaceX decided to cancel a Falcon 9 launch yesterday, carrying 52 Starlink satellites.

The first stage booster had previously launched 10 times, though it is not clear if this is the cause of the delay.

It’s not the first time SpaceX has delayed a launch indefinitely after a static fire test, but it is the first time in years. SpaceX semi-regularly stands down from launch attempts to conduct inspections or complete minor repairs or component replacements when data is amiss or contradictory, but those plans tend to mention the next launch target. This time, even SpaceX’s website has been scrubbed to say that “a new target launch date [will be announced] once confirmed.”

The last time a prelaunch static fire was explicitly blamed for a launch delay was in August 2019, when SpaceX fired up a Falcon 9 rocket ahead of its Amos-17 launch, didn’t like what it saw, decided to replace a valve on the booster, and then conducted a second static fire test to clear the rocket to launch. It’s possible that Starlink 2-4’s sequence of events will end up being similar.

Today’s blacklisted American: Anti-Semitic attacks skyrocket on college campuses

2:44 pm

The coming genocide
What American universities are aggressively working towards

They’re coming for you next: According to a recent study, anti-Semitic attacks against Jews have increased drastically on American college campuses in 2021 and 2022, rising in lock-step with the introduction of critical race theory and its anti-white, anti-American, and pro-Marxist agenda.

There were 254 attacks on 63 different college campuses with large Jewish populations, with Harvard University, the University of Chicago, Tufts University, UCLA, and Rutgers University having the highest number of incidents, according to a report by the AMCHA Initiative, a Jewish advocacy group that says its findings expose an “insidious,” never-before-revealed campus trend.
