A crack on Mars more than 600 miles long
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on March 29, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “troughs in Labeatis Fossae.” On Mars, the word “fossae” is used to indicate regions where there are a lot of parallel fissures. Though there are a few examples where such fissures might have been caused by the movement of ice or water, carving out the channel, in almost all cases this is not the cause. Instead, fossae are usually formed when the surface stretches, either because underground upward pressure pulls it apart, or because there is a sideways spread at the surface. The resulting cracks are generally considered what geologists call “grabens,” depressions caused at faultlines when the ground on either side moves apart in some manner.

In this case the break in the trough proves this is a graben, though why it broke at this spot is not clear.

Today’s blacklisted American: Democrats demand Elon Musk be censored and arrested simply for disagreeing with them

12:25 pm

Robert Reich
Robert Reich, labor secretary under Bill Clinton

They’re coming for you next: Based on the behavior of loyal Democrats in the past five years, no on should be surprised by this story. Several big name Democratic Party supporters have now called for the complete censorship and imprisonment of Elon Musk for the horrible crime of disagreeing with them and campaigning for their opposition.

First we have Robert Reich, that petty dictator who was once secretary of labor under President Bill Clinton and teaches public policy at — you guessed it — the University of California in Berkeley. In an op-ed for the leftist British newspaper The Guardian, Reich claims Musk is “out of control” and for this crime he must be squelched. First he calls for a global boycott of Tesla and X but then tops this demand with some decidedly tyrannical desires:

Musk: First unmanned Mars Starship targeting a ’26 launch

9:15 pm

The prime and secondary Martian landing sites for Starship

According to a tweet yesterday by Elon Musk, SpaceX is aiming for a 2026 launch of its first unmanned Starship to Mars.

The first Starships to Mars will launch in 2 years when the next Earth-Mars transfer window opens. These will be uncrewed to test the reliability of landing intact on Mars. If those landings go well, then the first crewed flights to Mars will be in 4 years.

Flight rate will grow exponentially from there, with the goal of building a self-sustaining city in about 20 years.

The graphic to the right indicates the planned landing zone, with the four red dots the four prime locations. Three of the four are very flat, though they also appear to have a lot of very near-surface ice, accessible simply by digging a shovel into the ground. Attempting to land at any will definitely test Statship’s ability to land on Mars intact. A global map of Mars is shown below, showing the location of this landing zone. The map shows where researchers believe the saltiest water on Mars would be. According to this data, in the Starship landing zone some of that near-surface ice will turn to liquid brine a little less than one percent of each year. Otherwise it will be more easily processed for drinking and fuel.

As always with these ambitious predictions, Musk is aiming high, with the likelihood that this first mission will not make that ’26 date. At the same time, he is making it very clear that a first attempt will certainly happen by ’28.

I also think the timing of this announcement is intriguing, coming one day after NASA was forced to cancel the launch in October of two Mars orbiters because it could not be certain Blue Origin would have the New Glenn rocket ready on time. Musk’s response is to say that SpaceX is now about to begin regularly privately funded and privately built missions to Mars, on a schedule, essentially asking: “Which company would you choose to do things in space?”

Starliner lands in New Mexico unmanned without problems

9:47 am

Boeing’s Starliner manned capsule landed last night at White Sands in New Mexico, the undocking, de-orbit, and descent occurring as planned with no hitches.

The mission however was not a full success. Intended as the first manned demo flight of the capsule, it did not complete that demonstration. It took astronauts up to ISS, but did not bring them home. NASA made the decision that the technical problems during launch and docking to ISS were sufficient enough to preclude putting the astronauts back on board for the return flight.

NASA says it “will review all mission-related data” before deciding whether to certify the capsule for operational manned flights. The agency has essentially two choices. First, it could decide that the successful return with no hitches of this manned flight, even with no one on board, fulfilled Boeing’s obligations. It will certify the capsule, allowing Starliner’s next manned mission to fly with NASA paying the bill. Doing so however would likely expose NASA to a lot of bad publicity, since the press right now sees Boeing as the root of all technical evil, and will pile on to the agency for putting safety last.

Second, NASA could avoid that bad press and play hard-nosed and demand another manned demo flight, on Boeing’s dime, as required by contract. If so, however, expect Boeing to refuse to do it, citing the cost and the company’s fiscal responsibility to its shareholders. Even if successful Boeing is unlikely to ever recover those costs through passenger sales.

Based on this negotiating situation, I predict NASA will choose the former. The successful landing suggests this is probably the right decision. It however will not do so immediately, but will release a series of announcements touting the positive results from its review of that “mission-related data”. By dribbling out each positive result bit-by-bit, the goal will be to soften the press so that when the agency finally certifies Boeing for that next manned mission and thus agrees to pay for it, the press will not pile on so hard.

At least, that will be the agency’s hope. The mainstream propaganda press however doesn’t usually read NASA press releases, and even when it does it knows so little about the subject that it almost always comes to the wrong conclusion. Moreover, its present desire to attack Boeing in all conditions will likely help it report these stories badly.

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 founder of the Mars Society.

NASA cancels launch of its two Escapade Mars Orbiters due to Blue Origin delays

2:59 pm

After reviewing the status of launch preparations by Blue Origin of its New Glenn rocket, NASA today decided to cancel the launch because it appeared that Blue Origin would not be able to meet the October 13-21 launch window for sending the agency’s two Escapade orbiters to Mars.

NASA announced Friday it will not fuel the two ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft at this time, foregoing the mission’s upcoming October launch window. While future launch opportunities are under review, the next possible earliest launch date is spring 2025.

The agency’s decision to stand down was based on a review of launch preparations and discussions with Blue Origin, the Federal Aviation Administration, and Space Launch Delta 45 Range Safety Organization, as well as NASA’s Launch Services Program and Science Mission Directorate. The decision was made to avoid significant cost, schedule, and technical challenges associated with potentially removing fuel from the spacecraft in the event of a launch delay, which could be caused by a number of factors.

The press release of course is vague about why the launch has been canceled, but the reasons are obvious if you have been paying attention. Though Blue Origin has clearly been making progress towards the first launch of New Glenn, recent reports suggested strongly that it would be impossible for it to assemble the rocket, integrate the two orbiters, and get everything on the launchpad on time.

Rocket Lab, which built the orbiters, of course fully supported the decision, though that company very much wanted it to fly now to demonstrate its ability to make low cost smallsat planetary probes.

This failure of Blue Origin to meet this deadline speaks poorly of the company. To serve the satellite and especially the planetary research community rocket companies must be able to launch on schedule and on time. Blue Origin has failed to do so in this case. It appears Jeff Bezos needs to ramp up the pressure on his moribund company to finally get it to perform in the manner he desires, as described by Bezos himself recently.

Want to buy an original copy of the U.S. Constitution?

12:49 pm

The final ratified Constitution
The first page of the Constiution as eventually
ratified by the states.

One of only eight signed “ratification copies” of the United States Constitution and the only one known to be in private hands is now up for auction to be sold on September 28, 2024, the 237th anniversary of the day the existing congress (formed under the failing Articles of Confederation) voted to send it to the states for ratification.

The minimum bid is one million, but it will not be surprising if the auction produces a much higher selling price. The public will be able to view the document on September 13, 2024 from 1:00 pm to 4:30 pm (Eastern) at the Federal Hall National Memorial at 26 Wall Street in New York, the location where that congress debated and voted for the new Constitution.

The document’s recent history is intriguing.

This incredibly rare document was discovered in 2022 at Hayes Farm, a 184-acre plantation in Edenton, North Carolina. The property was purchased in 1765 by Samuel Johnston, who in 1787-1789 was governor of North Carolina and presided over the state’s two ratification conventions. In 1865, it was acquired by the Wood family, which has held it for seven generations. The document was found inside an old filing cabinet in 2022 when the property was being cleared out and sold to North Carolina for preservation under the care of the Elizabeth Vann Moore Foundation with assistance from the Edenton Historical Commission and the Town of Edenton.

If you want to register to submit your own bids, you can do so here.

Will NASA give up on Starliner after its present contracts are completed?

11:17 am

According to an article today at Ars Technica, there are indications that NASA will not buy any further flights of Boeing’s Starliner capsule after it finally completes its present three-launch contract.

NASA hasn’t decided if it will require Boeing to launch another test flight before formally certifying Starliner for operational missions. If Starliner performs flawlessly after undocking and successfully lands this weekend, perhaps NASA engineers can convince themselves Starliner is good to go for crew rotation flights once Boeing resolves the thruster problems and helium leaks.

In any event, the schedule for launching an operational Starliner crew flight in less than a year seems improbable. Aside from the decision on another test flight, the agency also must decide whether it will order any more operational Starliner missions from Boeing. These “post-certification missions” will transport crews of four astronauts between Earth and the ISS, orbiting roughly 260 miles (420 kilometers) above the planet.

NASA has only given Boeing the “Authority To Proceed” for three of its six potential operational Starliner missions.

Apparently NASA has not decided whether to commit to any more Starliner operational manned flights behind those first three.

There are obvious good reasons for NASA’s hesitancy, most of which center on Boeing and its inability to get Starliner flying without technical problems. One that isn’t as obvious however is ISS itself. Boeing has taken so long in getting Starliner flying that the end of ISS in 2030 is now looming. There are only so many manned flights that NASA needs to buy before the station is decommissioned. Afterward the agency will still need to hire ferrying services to the new privately owned stations, but it is too far in the future to consider either SpaceX or Boeing for those decisions.

Local Texas authorities fine SpaceX for dumping potable water in Boca Chica

10:33 am

In what is simply another case of apparent harassment fueled by a tiny minority of anti-Musk activists, local Texas authorities have fined SpaceX a whopping $3,750 for dumping potable water at Boca Chica during the last test launch of its Starship/Superheavy rocket.

Late last month, the Texas Commission on Environmental Quality shared that SpaceX failed to get authorization to discharge industrial wastewater into or adjacent to surrounding wetlands, resulting in a $3,750 penalty. The wastewater SpaceX is charged with releasing comes from a water deluge system for its massive Starship rocket. The deluge system is used to absorb heat and vibration from the rocket engines firing.

This article is typical of most of our leftist mainstream press. It pushes the false claims of those activists — such as their insistence they represent everyone in the south Rio Grande Valley and that the water was “industrial wastewater.” First, they represent almost no one in south Texas, as almost everyone there is very happy with SpaceX and the billions of dollars and tens of thousands of jobs it is bringing to the area. For example, these groups recently held an event on the beaches near SpaceX facilities “to fight for its preservation, which they view as being in jeopardy since the arrival of Elon Musk’s SpaceX.”

Only about a dozen people showed up.

Second, the water is not “industrial wastewater.” As Elon Musk noted in a tweet, “Just to be clear, this silly fine was for spilling potable drinking water! Literally, you could drink it.”

Nonetheless, this manufactured environmental issue has clearly been used to stall SpaceX’s efforts. The company had said it was ready to do the next test launch of Starship/Superheavy on August 8, 2024. It is now a month later, and the FAA has still not issued the launch license. It is possible that part of the reason for the delay is because SpaceX has decided it will attempt to bring Superheavy back to the launch tower at Boca Chica, where the tower’s chopstick arms will try to capture it on landing. If so, the FAA might be demanding more assurances of safety than SpaceX can reasonably provide.

The delay however is also almost certainly caused by this fake environmental water issue. The FAA apparently has been forced to deal with it, and that action has stalled all of its new regulatory harassment of SpaceX, including the process to approve a new environmental assessment of Boca Chica that would allow the company to launch as many as 22 times per year.

Dust storm in Jezero Crater

An update today from the science team for the Mars rover Perseverance included the picture to the right, cropped, reduced, and sharpened to post here and taken by the rover on August 20, 2024. As the update noted,

It is dust-storm season on Mars! Over the past couple of weeks, as we have been ascending the Jezero Crater rim, our science team has been monitoring rising amounts of dust in the atmosphere. This is expected: Dust activity is typically highest around this time of the Martian year (early Spring in the northern hemisphere). The increased dust has made our views back toward the crater hazier than usual, and provided our atmospheric scientists with a great opportunity to study the way that dust storms form, develop, and spread around the planet.

The yellow lines on the overview map above indicate the approximate direction of the photo. The blue dot marks Perseverance’s present position, with the red dotted line its planned route and the white dotted line its actual travels.

At the moment this dust storm is localized to the region around Jezero Crater, and based on past seasonal dust storms, is not expected to expand to a global storm.

China lands its X-37B copycat reusable mini-shuttle

9:41 am

China’s state-run press today announced in a short statement that its X-37B copycat reusable mini-shuttle has landed after a 268 day mission.

This was the spacecraft’s third mission since 2020, with the second lasting 276 days and the first two days. All three missions have involved the release of secondary objects, with the last two flights including additional rendezvous maneuvers with one object. It is not clear if that object on this third flight was ever redocked or grabbed by the mini-shuttle for return to Earth. Such a recapture is thought to have occurred on the second flight.

Very little information about these flights has been released by China.

ESA releases images taken by BepiColombo during Mercury fly-by

9:29 am

Mercury as seen by BepiColombo September 4, 2024
Click for original image.

The European Space Agency (ESA) yesterday released images taken by the BepiColombo probe as it completed its fourth fly-by of Mercury on its long journey to enter orbit around that planet.

The picture to the right, cropped, reduced, and sharpened to post here, was taken four minutes after the closest approach of about 103 miles.

Four minutes after closest approach, a large ‘peak ring basin’ came into BepiColombo’s view. These mysterious craters – created by powerful asteroid or comet impacts and measuring about 130–330 km across – are called peak rings basins after the inner ring of peaks on an otherwise flattish floor.

This large crater is Vivaldi, after the famous Italian composer Antonio Vivaldi (1678–1741). It measures 210 km across, and because BepiColombo saw it so close to the sunrise line, its landscape is beautifully emphasised by shadow. There is a visible gap in the ring of peaks, where more recent lava flows have entered and flooded the crater.

BepiColombo still has two more fly-bys of Mercury to do before entering orbit in November 2026. At that time the spacecraft’s two orbiters, one from Europe and the other from Japan, will separate and take up complementary orbits.

NASA requests industry proposals for its canceled satellite refueling demo mission

9:14 am

NASA today issued a request-for-information, asking the commercial aerospace industry for “alternate use” ideas for using the “flight hardware, test facilities, and experienced personnel” of its canceled satellite refueling demo mission, dubbed OSAM.

The request suggests NASA is hoping a private company will pick up the mission at its own cost, thus getting it off NASA’s hands. The agency canceled it because it is almost a decade behind schedule, hundreds of millions of dollars over-budget, and has an absurd workforce of 450 people. The agency is also under pressure from the Senate not to cancel the project, because our idiotic elected officials like to make-believe that funding these make-work projects accomplishes something.

Even if a private company takes on the project, if it does so at its own expense that workforce is certain to be reduced, possibly as much as 90%. No commercial satellite company is going to get saddled with that cost. It will want NASA to pay the bill.

NASA confirms its giant solar sail is tumbling but doing so as planned

9:04 am

NASA today outlined the testing that its engineers are doing with the deployed 860 square foot Advanced Composite Solar Sail System (AC3), including the planned tumbling that an amateur astronomer detected based on the fluctuating brightness of the sail.

Currently orbiting Earth, the spacecraft can be seen with its reflective sails deployed from the ground. As part of the planned deployment sequence, the spacecraft began flying without attitude control just before the deployment of the booms. As a result, it is slowly tumbling as expected. Once the mission team finishes characterizing the booms and sail, they will re-engage the spacecraft’s attitude control system, which will stabilize the spacecraft and stop the tumbling. Engineers will then analyze flight dynamics before initiating maneuvers that will raise and lower the spacecraft’s orbit.

The release adds that NASA has added a feature to its mobile app that will help anyone spot the sail in the night sky.

Czech government signs deal with Axiom to fly astronaut

8:58 am

The Czech government and the American space station company Axiom have now signed an agreement to fly Czech’s ESA astronaut Aleš Svoboda on a future spaceflight.

No date for the mission has been set, nor is it clear whether it will be an orbital mission or will dock with either ISS or Axiom’s own station once launched. The release also said nothing about a launch vehicle or spacecraft for transporting Svoboda into space, though that vehicle will almost certainly be a Falcon 9 and a Dragon capsule.

Curiosity takes another look south into Gediz Vallis

Looking south inside Gediz Vallis

Overview map
Click for interactive map.

Cool image time! As it has been more than a month since I lasted posted a cool landscape image from the Mars rover Curiosity, it seemed time to upload the panorama above, changed not at all to post here and taken by the rover’s right navigation camera on September 4, 2024.

The blue dot on the overview map to the right marks Curiosity’s present position. The yellow lines indicate the approximate direction of the panorama’s view. The red dotted line indicates Curiosity’s planned route, with the white dotted line marking its actual path. After spending most of the last month on a drilling campaign at the southernmost point of its travels, the science team had Curiosity retreat northward, where it will eventually head uphill to the west to swing around that mountain to head south in a parallel canyon.

The panorama looks into the slot canyon Gediz Vallis that Curiosity has been exploring for a little more than a year. The light colored mountains are what the scientists call the sulfate-bearing unit, a region on the higher slopes of Mount Sharp that is likely to have a very alien geology and chemistry, when compared to what is seen on Earth. Mount Sharp itself is beyond these peaks, not visible because it is about 26 miles away and blocked by these lower mountains.

Since landing on Mars a dozen years ago, the rover has traveled 20 miles and climbed about 2,500 feet. Getting to the top of Mount Sharp will therefore probably take more than one or two decades more of travel.

A former Democratic Party majority leader in California sees the light

1:33 pm

The Democratic Party today
The Democratic Party today

If she of all people can do this, why can’t so many other ordinary Democrats? Gloria Romero, former Democratic Party majority leader in the California state senate from 2005 to 2008, announced publicly yesterday that she has dumped her lifelong allegiance to that party, switched her registration to the Republican Party, and furthermore enthusiastically endorsed Donald Trump for president. From her statement:

“Today I say ‘goodbye, adios,’ I’ve had enough. I am now another near-lifelong Democrat who is joining the growing number of people, including key groups like Latinos, who are leaving the Democratic Party. This is not the Democratic Party that I once championed. I do not recognize it anymore, and I cannot continue. I changed my voting registration today as the sun was rising to Republican, which has, under Donald Trump, become the champion of working people, the big tent. And indeed, I will vote for Donald Trump this fall.”

She proceeded to list the many tyrannical actions taken by the Democratic Party recently that led her to this decision, including its backroom deals that blocked any others from running against Joe Biden during the presidential primaries and then dumped him for Kamala Harris. She also cited that party’s support for the queer agenda, for “locking people up for free speech,” for supporting “endless war” everywhere, and for allowing an invasion of illegal immigrants, including violent felons.

Above all she cited the Democratic Party’s failed school policies, from favoring the school unions that do not educate kids but funnel money into the party’s campaign coffers to encouraging anti-Semitism at universities. “The Democratic party thrives off of this failure shamefully … even as our children fall farther and farther behind in reading, writing and the ability to compete internationally.”

None of her criticisms of the Democratic Party are wrong. » Read more

(credit: Christine Hillman Photography).

Rebekah Massie, the woman who was arrested two weeks ago while attempting to speak during the open comment period at the city council meeting in Surprise, Arizona, has now sued the town’s mayor Skip Hall, the policeman who arrested her, and the city council for violating her 1st amendment rights.

The lawsuit, filed by her attorneys at the Foundation for Individual Rights and Expression (FIRE), can be read here. From FIRE’s press release:

FIRE’s lawsuit aims to permanently stop enforcement of the city policy used to silence Rebekah and obtain damages. In the meantime, FIRE moved for a court order to stop the city’s use of the policy while the lawsuit is pending. The lawsuit names the City of Surprise, Mayor Hall, and Steven Shernicoff, the officer who arrested Rebekah, as defendants. Quintus Schulzke, a Surprise resident who frequently makes public comments at city council meetings, also signed on as a plaintiff. Without legal intervention, Schulzke — or any other member of the public — risks arrest simply for speaking his mind to his elected representatives.

I have embedded the video of Massie’s arrest below. When I first reported this story I suggested Massie find a good lawyer and sue. It is great she wasted no time doing so. Even better, she is personally suing the mayor and the police officer who arrested her, and demanding punitive damages.

Mars loses hydrogen at very different rates, depending on the planet’s distance from the Sun

11:37 am

Hubble uv images of Mars atmosphere
Click for original image.

Scientists using data from both the MAVEN Mars Orbiter and the Hubble Space Telescope have determined that the rate in which Mars loses hydrogen and deuterium varies considerably during the Martian year, with the rate going up rapidly when the red planet reaches its closest point to the Sun. The picture to the right, reduced to post here, shows the data from Hubble.

These are far-ultraviolet Hubble images of Mars near its farthest point from the Sun, called aphelion, on December 31, 2017 (top), and near its closest approach to the Sun, called perihelion, on December 19, 2016 (bottom). The atmosphere is clearly brighter and more extended when Mars is close to the Sun.

Reflected sunlight from Mars at these wavelengths shows scattering by atmospheric molecules and haze, while the polar ice caps and some surface features are also visible. Hubble and NASA’s MAVEN showed that Martian atmospheric conditions change very quickly. When Mars is close to the Sun, water molecules rise very rapidly through the atmosphere, breaking apart and releasing atoms at high altitudes.

From this data scientists will be better able to map out the overall loss rate of water on Mars over many billions of years.

China significantly expands its international partners for its planetary program

10:34 am

According to China’s state-run press, it has recently signed cooperative agreements with a significant number of new nations for either its International Lunar Research Station project (ILRS) or other deep space planetary missions.

During the opening ceremony of a two-day space conference held in Tunxi, east China’s Anhui Province on Thursday, the China National Space Administration (CNSA) and its counterpart in Senegal signed an agreement on International Lunar Research Station (ILRS) cooperation.

At the conference, China’s Deep Space Exploration Lab (DSEL) inked memoranda of understanding with 10 institutions from countries including Serbia, Switzerland, the United Arab Emirates, Indonesia, Pakistan, Panama and South Africa. Also among the institutions are the Belt and Road Alliance for Science & Technology, the Foundation for Space Development Africa, and Africa Business Alliance.

Senegal is now the thirteenth nation to join China’s lunar base project, following Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. That partnership also includes about eleven academic or governmental bureaucracies.

The agreements involving China’s deep space exploration involve other missions to other planets, with those nations either providing science instruments or some other contribution. That Switzerland and the United Arab Emirates have signed deals suggests there is a rising desire in the west to team up with China because of its general success in space, compared to the problems other nations often experience when dealing with NASA and the U.S. If so, the competition will certainly heat up in the coming years. I hope in this competition that American private enterprise can make up for the failures of our government.

Amateur astronomer detects changes in the reflective light coming off of NASA’s orbiting solar sail

10:20 am

Observations by amateur astronomer Marco Langbroek of Delft Technical University in the Netherlands has detected significant changes in the reflective light coming off of the giant orbiting solar sail that NASA engineers recently deployed in orbit.

I observed the Solar Sail again in the evening of September 1, 2024, and this time the brightness of the Solar Sail was quite different. As it rose in the south, it became very bright, reaching magnitude 0 (as bright as the brightest stars in the sky). It then faded again, and next displayed a slow brightness variation with multiple bright maxima and very faint minima.

…The brightness seems to indicate a slow cycle of around half a minute. … The brightness variation could be suggestive of a slow tumble or wobble (a gyration around an axis) that must have been initiated after August 29, when it appeared more steady (apart from a brief bright flare, probably due to a favourable sun-sail-observer geometry).

The sail, dubbed the Advanced Composite Solar Sail System, was launched on April 23rd, and after some initial technical issues it was deployed from its small cubesat on August 30th, expanding to 860 square feet.

The changes Langbroek detected have all occurred after that deployment, and suggest one of two things. Either the NASA engineers are testing the sail’s maneuverability, as planned, and thus the sunlight reflecting off it changes, or there is a problem controlling it that NASA has not yet revealed. We will have to wait to find out.

New questions raised about the rocket startup Relativity

10:06 am

Link here. Apparently Relativity has had a number of problems developing its proposed large Terran-R rocket using the 3D printing technology the company has specialized in.

According to internal documents reviewed by Ars, Relativity had difficulty printing pressure domes for the Terran R rocket. One of the documents references a “large buckling event” with a printed dome. As a result, Relativity seems likely to purchase these pressure domes from a European aerospace company.

The details provided for the status of Terran-R are somewhat vague. There are claims its size has been revised, and that the company is now outsourcing construction of some parts to European vendors, but none of this is described with any specificity. All in all however it does appear the rocket’s first launch is facing a delay from its 2026 targeted launch date. Earlier reports had suggested this, and this new report reinforces that sense.

I still wonder if Relativity might find much greater and more immediate success marketing its sophisticated 3D printing technology to other industries.

China targets 2028 for its own Mars sample return mission

9:56 am

According to a report today in China’s state-run press, it now hopes to launch its own Mars sample return mission in 2028, dubbed Tianwen-3.

The report is very vague about the missions design. It notes that it will involve two launches, including “key technologies such as collecting samples on the Martian surface, taking off from the Red Planet, [and] rendezvous on the orbit around Mars.”

Based on China’s overall track record for its planetary program, it is likely that the launch will likely take place somewhat close to this schedule, though a delay of one or two years would not be unreasonable. If so, we are looking at either two or three different projects to bring Mars samples back to Earth at almost the same time.

The first is the NASA/ESA joint Mars sample return mission, which is presently far behind schedule with large cost overruns, all because the mission design has been haphazard and confusing. At the moment it involves an American lander, a European orbiter and return capsule, a Mars launch rocket to be built by Lockheed Martin, and at least one Mars helicopter. None of this however is certain, as NASA is right now asking industry for suggestions for redesigning the mission. It is presently hoping to bring its samples back sometime in the 2030s.

The second is this China mission, which appears to have some of the same planned components, which is not surprising considering China’s habit of copying or stealing other people’s ideas.

A third sample return mission might also be flown, by SpaceX using its Starship spaceship and Superheavy rocket. Both are built with Mars missions specifically in mind. SpaceX has also ready done work locating a preliminary landing zone. If so, it could possible attempt this mission at about the same time, independent of both China or NASA.

Or it might simply offer Starship as part of the redesigned NASA sample return mission. There is also the chance SpaceX would do both.

If I had to bet, I would say SpaceX (on its own) is the most likely to do this first, with China second. If SpaceX teams up with NASA then it will be a close race between NASA and China.

New Glenn’s 1st stage ocean-landing platform arrives in Florida

Blue Origin yesterday released images of the arrival at Port Canaveral in Florida of the landing platform, dubbed Jacklyn, to be used by the first stage of its New Glenn rocket when it returns to Earth.

Jacklyn is 380 feet long and 150 feet wide (116 by 46 meters), according to Space Offshore. It’s named after the mother of Jeff Bezos, the billionaire founder of Blue Origin. (“Jacklyn” is a nickname, however; the ship’s legal moniker is “Landing Platform Vessel #1.)

Jacklyn is a new ship that was specially designed to be a New Glenn landing platform, Space Offshore reports. Construction on the ship began in Romania last year and wrapped up in Brest, France in the last month or so. Jacklyn departed Brest for Florida on Aug. 8.

The first launch of New Glenn is presently scheduled for October 13, 2024, and will carry two Rocket Lab-built Mars Orbiters for NASA. The launch window for these orbiters is only eight days, so there is not much margin in getting ready for that launch. The arrival of the platform in Florida in time for that launch suggests Blue Origin will attempt to land the first stage right from the start.
