Ispace’s Resilience

Blue Ghost on February 13, 2025 successfully completed a long four-minute engine burn to complete its transfer from Earth to lunar orbit, with a target date for the actual landing on March 2, 2025.

Now that the lander is in lunar trajectory, over the next 16 days, additional maneuvers will take the lander from an elliptical orbit to a circular orbit around the Moon. Blue Ghost Mission 1 is targeted to land Sunday, March 2, at 3:45 a.m. EST.

NASA has also announced the live stream coverage during landing:

Live coverage of the landing, jointly hosted by NASA and Firefly, will air on NASA+ starting at 2:30 a.m. EST, approximately 75 minutes before touchdown on the Moon’s surface. Learn how to watch NASA content through a variety of platforms, including social media. The broadcast will also stream on Firefly’s YouTube channel. Coverage will include live streaming and blog updates as the descent milestones occur.

I will embed the Firefly live stream when it becomes available.

Texas commission rejects anti-SpaceX calls to deny company its Starship deluge water permit

2:27 pm

The Texas Commission on Environmental Quality this week strongly and finally dismissed the repeated demands by various fringe activist groups to shut down SpaceX’s launch operations at Boca Chica and the use of the deluge system designed to protect the launchpad and the Superheavy booster.

The Texas Commission on Environmental Quality on Thursday denied requests from a dozen area residents and several groups to reconsider the commercial space company’s permit to dump as much as 358,000 gallons of water into wetlands during tests and launches of its Starship rocket from its Starbase east of Brownsville.

Commission Chair Brooke Paup introduced the item as “quite a big deal,” then quickly moved to deny additional hearings on the subject and issue the permit. She said concerns raised by individuals and groups including Save RGV, the South Texas Environmental Justice Network and the Carrizo/Comecrudo Nation of Texas failed to identify “new factual information or an error that would alter the executive director’s decision.

“The hearing requesters did not show that their ability to practice their religion or engage in recreational activities will be affected in a manner different than the general public,” Paup said.

The commission admitted in its ruling that there had been numerous technical errors by both the commission and SpaceX when it initially approved the permit, but none of those errors were significant.

It appears this particular effort by a very tiny minority of leftist anti-Musk activists has finally been shut down. We can only hope that these groups will now fade away, not because they want to give up but because their funding could be gone. I suspect their money came from somewhere within the fraudulent grant programs at EPA and other federal agencies that DOGE has now identified and shut down.

Starlink Falcon 9 launch sets new reuse record for first stage

2:05 pm

Last night SpaceX successfully launched 21 new Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 26th flight, a new record for the Falcon 9 boosters. That number also exceeded the number of flights the space shuttle Endeavour completed in nineteen years from 1992 to 2011. This SpaceX booster however needed less than three and a half years to do it. Next shuttle record to beat is Columbia’s, which flew 28 times.

The 2025 launch race:

20 SpaceX
7 China
1 Blue Origin
1 India
1 Japan
1 Russia

A rose in space

A rose in space
Click for original image.

Cool image time! Using the Gemini South telescope in Chile, astronomers have taken a very beautiful picture, cropped, reduced, and sharpened to post here, of a nebula dubbed LH 88 that surrounds a star cluster and is located 160,000 light years away in the Large Magellanic Cloud.

The bright stars seen in the image are widely separated, but their motions through space are similar, indicating that they have a common origin. The layered nebulous structures in LH 88 are the remnants of stars that have already died. The delicate leaves of the rose were formed by both the shockwaves from supernovae and the stellar winds of the O and B stars.

The intense radiation of these super giant O and B stars — that burn fast and explode as supernova after only a few million years of life — not only shapes the nebula, it lights the nebula’s different atoms and molecules in different colors, with red/orange representing hydrogen and blue oxygen. The white areas indicate a mixture of both.

Astronomers demand more regulations to prevent industry from ruining the Moon’s “environment”

9:33 am

According to two articles yesterday in the British press (here and here), both quoting extensively one astronomer, if strong regulation and control (given to them of course) isn’t imposed immediately, the space tourism of billionaires is going to ruin the Moon’s pristine environment, which on its far side is especially perfect for radio astronomy. From the first link:

“There’s a rush of companies and states who might want to get in on the act on the moon,” said [astronomer Martin Elvis, who added that there were also other concerns. “There’s a desire there from the billionaire class, ‘Oh I would love to spend a week on the moon’. And you don’t need many billionaires to start adding up. If they go without coordination, then it’s a mess. We could well lose these unique opportunities to do science on a scale that we couldn’t possibly imagine.”

One of the most exciting possibilities is the use of the far side of the moon for radio astronomy. As all signals from the Earth are blocked, telescopes would, Elvis said, have the sensitivity to see into the so called “dark age” of the universe, after the big bang but before stars had formed.

Elvis is based at Harvard and also co-chairs a working group at the International Astronomical Union (IAU) that wants astronomers to be given full legal control of the Moon, preventing anyone from building anything without their permission so they can instead build their telescopes there instead.

The problem is that the astronomical community has so far shown little interest in building telescopes in space. It has instead focused on building giant Earth-based telescopes while trying to get governments to restrict the launch of satellite constellations that might interfere with those telescopes. Now it wishes to restrict lunar development as well.

Elvis however admits “It’s a sort of first come, first served situation, which encourages people to rush in and do things without thinking too hard.” Let me translate: Everyone else is beating us to the Moon because we haven’t been interested in going, so now that we might be interested we want governments to shut down our competition.

It is long past time for astronomers and the IAU to stop trying to use government to squelch everyone else and get in the game. Initiate the building of telescopes both in space and the Moon. Not only are these better places to build telescopes than on Earth, it will give astronomers some credibility when they ask others to give them their own space.

Blue Origin’s CEO lays off 10% of Blue Origin’s workforce to reduce “bureaucracy”

8:56 am

Dave Limp, Blue Origin’s CEO since late in 2023, announced yesterday that the company is laying off 10% of its workforce to in order to reduce the company’s overhead and make it more efficiently run.

From his company-wide email:

We grew and hired incredibly fast in the last few years, and with that growth came more bureaucracy and less focus than we needed. It also became clear that the makeup of our organization must change to ensure our roles are best aligned with executing these priorities. Sadly, this resulted in eliminating some positions in engineering, R&D, and program/project management and thinning out our layers of management.

I think Limp has finally gotten a full handle on the company after a year and a half in charge, and has now begun reshaping it from the five years of bloated and failed inactivity that occurred during the reing of the previous CEO, Bob Smith. Smith tried to turn Blue Origin into another old-fashioned big space company like Boeing or Northrop Grumman, big and slow and inefficient. Thus, nothing happened there from 2017 to 2023. Since Limp took over Blue Origin has begun to function more like SpaceX, and thus has begun to move. These layoff are probably Limp’s first main effort to clean house.

The movement to ban smartphones in schools widens

1:39 pm

The smart phone: Bad for kids
The smart phone: Proven very bad for kids

According to a detailed Washington Examiner story earlier this week, the campaign to ban smartphones in schools is expanding rapidly, with widespread bi-partisan support, backed up by studies and school reports that consistently show significant improvements in student behavior and learning when smart phones are banned.

Eight states have banned cellphone use in schools, with Florida being the first to do so when Gov. Ron DeSantis (R-FL) signed a bill into law in 2023. The legislation in the Sunshine State allows teachers to ban cellphone use during classroom instruction and authorizes them to hold a student’s phone if it becomes a distraction.

Florida was followed by Indiana, Louisiana, Virginia, California, Minnesota, South Carolina, and Ohio in passing similar bans that have either been enacted or will be in the coming year. Each of the states that have passed bans has taken different approaches to implementing the policy.

Fifteen other states have proposed a ban, and an additional eight states are either doing test bans in selected regions or have issued recommendations endorsing bans. That makes for a total if 32 states out of 50 that are working to keep smart phones away from kids when they are in school.

The best aspect of this is the generally bi-partisan nature of the movement. While most of the initial action occurred in red states controlled by conservative politicians, blue states like California and Minnesota have also joined in. A Minnesota middle school for example was an early practitioner of the ban in 2023, finding it not only improved classroom participation, but the entire social atmosphere in the school improved. In California meanwhile Democrat Governor Gavin Newsom signed a law restricting smartphone that takes effect in July 2026. Even Washington, D.C. is debating legislation to institute a school ban.

The sooner the better. Kids don’t need smart phones. All they really need is a dumb phone to call their parents in case of an emergency. And when they are in school this is even less necessary. Spending their time staring at a screen is the worst way to learn to live with other humans, a learning experience that is probably their number one class assignment.

Pits formed from sublimating underground ice on Mars?

12:29 pm

Pits formed from sublimating underground ice
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 31, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “Impact Ejecta with Marginal Pits,” though even on the full image I am not sure what the impact ejecta is. The pits themselves appear to have formed when near-surface ice sublimated away during the summer months. The location is at 59 degrees north latitude, deep within the Martian northern lowland plains. Since orbital data suggests much of those plains at this latitude has an ice table of some thickness near the surface, it is very reasonable to assume these pits formed when summer sunlight heated that ice, turning it to gas which eventually pushed out to form the pits.

But what about the impact ejecta? Where is it? And where is the crater from that impact?

Another Democrat demonstrates her stupidity and ignorance, demanding NASA’s acting administrator revoke Musk’s access to headquarters

9:57 am

Congresswoman Grace Meng (D-New York)
Congresswoman Grace Meng (D-New York), describing
her terror when ordinary Americans walked through the
Capitol on January 6th, almost all of whom simply took
pictures. Click for video.

Proving she knows nothing about the Constitution and the powers it gives to the President, congresswoman Grace Meng (D-New York) earlier this week sent a letter to NASA’s acting administrator Janet Petro demanding that Petro revoke any access to the agency’s headquarters by Elon Musk as part of his work auditing government operations as part of Department of Government Efficiency (DOGE).

Meng’s letter [pdf] is quite entertaining, especially because it repeats the new Democratic Party talking point that somehow because DOGE employees, including Musk, were “unelected” their access is inappropriate. How stupid. Except for the president, everyone who works in the executive branch of government is “unelected.”

That Meng also thinks NASA’s acting administrator has the power to block access to someone hired specifically by the president to do this work shows us how ignorant she is of the Constitution and basic law. Petro can’t cancel Trump’s orders, even if she wants to. Trump is her boss, and if he tasks Musk and DOGE to audit NASA’s books, she must comply.

There is only one part of Meng’s demand that makes some sense, where she demands Petro “set clear and public ground rules” to keep Musk from getting access to proprietary information of other space companies. Musk certainly has a conflict-of-interest issue at NASA, and such rules make sense. I am also quite sure that Musk is well aware of this issue, and will purposely leave the DOGE audit to others.

Rocket Lab delivers its third service module for Varda’s orbiting capsules

9:35 am

Rocket Lab yesterday announced it has completed and delivered its third Pioneer service module used in conjunction with the capsules of the in-space manufacturing company Varda, which flies these capsules in orbit for a variety of customers.

The spacecraft will support Varda’s next orbital processing and hypersonic reentry mission, W-3. Earlier this month, the Company’s second spacecraft for Varda, W-2, successfully launched and is currently operating on orbit. Carrying payloads from the Air Force Research Laboratory and NASA’S Ames Research Center, W-2 will also conduct research to expand the capability and capacity of Varda’s pharmaceutical processing hardware in orbit before it’s hypersonic re-entry and recovery in South Australia.

Like its predecessors, W-3 is based on Rocket Lab’s Pioneer spacecraft, leveraging vertically integrated spacecraft components and subsystems, including spacecraft propulsion, flight software, avionics, reaction wheels, star trackers, separation system, solar panels, radios, composite structures and tanks, and more. The spacecraft will provide power, communications, propulsion, and attitude control for Varda’s 120kg manufacturing capsule, which uses microgravity conditions to develop products that are difficult or impossible to create on Earth.

That hypersonic test for the military is presently scheduled for March 2025. Meanwhile Rocket Lab is building the fourth service module for Varda, as part of a four-spacecraft deal.

If Varda begins generating revenues from these first four capsules, it will then likely sign another deal with Rocket Lab.

Chinese pseudo-company GalaxySpace successfully tests its cell-to-satellite system

9:25 am

The Chinese pseudo-company GalaxySpace yesterday successfully proved its its cell-to-satellite technology works, using a smartphone to connect with one of its recently launched satellites.

At 10:28 a.m., a satellite from the constellation passed over the conference venue in the Beijing Economic-Technological Development Area. On-site staff used their mobile phones to connect to the satellite via a terminal device installed on the rooftop. Through a gateway station in Beijing, they established a connection with personnel in Beijing and Thailand.

Calling Thailand was significant because it signaled the signing of a deal with a major Thailand telecommunications operator to provide this service to that country.

French rocket startup signs Spanish rocket engine startup to provide attitude thrusters

9:15 am

The French rocket startup MaiaSpace, a subsidiary of Airbus, has awarded the Spanish rocket engine startup Arkadia Space a contract to provide the small attitude thrusters used to maintain the rocket’s course.

MaiaSpace hopes to do its first test orbital launch of its smallsat rocket in 2026, launching from a new commercial launchpad at French Guiana.

Arkadia’s thrusters are somewhat radical.

Arkadia Space, founded in 2020 in Castellón, Spain, develops hydrogen peroxide-based propellant systems for satellites and platforms with a mass of more than 50 kilograms. “The hydrogen peroxide-based propellant offers exceptional performance while significantly reducing cost and environmental impact compared to traditional hydrazine-based Reaction Control Systems,” according to the news release.

Hydrazine thrusters, while practical and lightweight, have the problem that the fuel is very toxic, and requires safety precautions to prevent injury to employees or the public. Using hydrogen peroxide instead likely reduces this issue significantly.

Judge okays vote on whether SpaceX’s Boca Chica facility can incorporate as city

9:03 am

After reviewing the local petition submitted by SpaceX requesting permission, a local judge as signed an order allowing the citizens of Boca Chica to vote on whether they can incorporate as city in Texas.

The incorporation petition, [Cameron County Judge Eddie] Treviño explained, was duly signed by at least ten percent of the qualified voters of Starbase. Additionally, the petition satisfied the statutorily required elements and set forth satisfactory proof that Starbase contains the requisite number of inhabitants as required by law and the area to be incorporated is not part of another incorporated city or town.

Since the submitted petition met all statutory requirements, Treviño said he is required under Section 8.009 of the Texas Local Government Code to order that an incorporation election be held on a specific date and at a designate place in the community.

The election is set to occur during the general election on Saturday, May 3rd, 2025.

SpaceX itself had organized the petition and submitted it to the county in mid-December, noting that it already “…currently performs several civil functions around Starbase due to its remote location, including management of the roads, utilities, and the provision of schooling and medical care for the residents. Incorporation would move the management of some of these functions to a more appropriate public body.”

Expect the petition to be approved, making Starbase at Boca Chica one of the most spectacular company towns ever to exist.

European underwater neutrino telescope detects most powerful neutrino ever

8:53 am

A European underwater neutrino telescope that is still under construction recorded evidence in February 2023 of most powerful neutrino particle ever detected.

KM3NeT’s two neutrino detectors — one off the coast of Sicily, the other near southern France — are still under construction but already collecting data. Both contain cables hundreds of meters tall, which are strung with bundles of light sensors anchored to the seafloor.

When cosmic neutrinos interact with matter in or near a KM3NeT detector, they spawn charged particles such as muons. As those muons careen through water, they give off feeble flashes of bluish light that KM3NeT’s sensors can pick up. Clocking when different sensors spot this light can reveal a particle’s path; the brightness of the blue hue reflects the particle’s energy.

On February 13, 2023, the detector near Sicily was run through by an extremely energetic muon traveling nearly parallel to the horizon. At the time, only 21 of the planned 230 sensor cables were in place. Based on the muon’s energy and trajectory, KM3NeT scientists determined it must have been spawned by a neutrino from space rather than a particle from the atmosphere.

Simulations suggest the neutrino’s energy was around 220 petaelectron volts. The previous record holder boasted around 10 petaelectron volts.

Tracking that trajectory backwards, astronomers say the particle came from a region of space where there are a lot of active galaxies, any one of which could be the source of the neutrino. It is also possible the neutrino came instead from an interaction of high energy cosmic rays and the photons from the faint microwave background left over from the Big Bang.

As noted very correctly by one scientist, “At this point, it’s very difficult to make conclusions about the origins,” says Kohta Murase, a theoretical physicist at Penn State not involved in the research. “It’s dangerous to rely on one event.”

Hal Holbrook – Lincoln’s second inaugural address, in honor of his birthday

An evening pause: I last posted a recreation in April 2017. Today, on Lincoln’s birthday, I present a recreation by Hal Holbrook, performed live on the Ed Sullivan Show on February 13, 1966.

As I wrote in 2017, “Listen to the words, however. This is no pandering speech, as we routinely see today. It is hard, muscled, and honest, bluntly recognizing that all, from both sides of the Civil War, must pay for the scourge of slavery.”

Modern academia: “We aren’t going to hire another white guy, are we?”

1:52 pm

Whites need not apply
Whites need not apply.

The quote in the headline above comes from a lawsuit [pdf] filed by a former professor at the University of Illinois-Chicago, Stephen Kleinschmit, who was eventually terminated because he had raised concerns within his department about its hiring practices, which beginning in 2019 became entirely focused on choosing its new faculty employees solely on whether they were born to the correct race, not on their talents or qualifications.

Kleinschmit raised his concerns because he was required to participate in the hiring process, and feared if he did not do so it “would make him a participant in illegal activities for which he would be held liable.” Instead of recognizing the clearly discriminatory and illegal nature of its racial hiring practices, however, the department decided to terminate Kleinshcmit’s contract instead.

He was ultimately terminated in August 2023 spring semester, ostensibly as a result of the need for “budget cuts.” Kleinschmit said the decision to fire him at that time appeared to be intentional, to not only cut him loose from his job at UIC, but also deny him the opportunity to seek employment at another university for more than a year.

However, Kleinschmit said he – the department’s only white male faculty member – was the only faculty member terminated at that time, despite claims of lack of finances, even as UIC moved forward with plans to hire more “diverse” faculty.

The complaint noted that Kleinschmit’s old job was later posted as eligible for hiring. But now the job ad was written in a way to encourage non-white male applicants, “as UIC shifted resources to a new job focused on fulfilling its racially discriminatory goals.” [emphasis mine]

In other words, the department fired its only white professor in order to replace him with a minority.

NASA announces March 12, 2025 as new launch date for next crew to ISS

9:47 am

NASA yesterday announced that it is now targeting March 12, 2025 as new launch date for sending the next crew to ISS, thus moving that date up about one week.

The earlier launch opportunity is available following a decision by mission management to adjust the agency’s original plan to fly a new Dragon spacecraft for the Crew-10 mission that requires additional processing time. The flight now will use a previously flown Dragon, called Endurance, and joint teams are working to complete assessments of the spacecraft’s previously flown hardware to ensure it meets the agency’s Commercial Crew Program safety and certification requirements. Teams will work to complete Dragon’s refurbishment and ready the spacecraft for flight, which includes trunk stack, propellant load, and transportation to SpaceX’s hangar at 39A at NASA’s Kennedy Space Center in Florida to be mated with the mission’s Falcon 9 rocket. This will be the fourth mission to the station for this Dragon, which previously supported the agency’s Crew-3, Crew-5, and Crew-7 flights.

Both NASA and SpaceX are touting this as a great decision because it will allow the present ISS crew (which includes the two astronauts initially launched on Starliner last year) to get home quicker.

The truth is that this decision really hides the fact that both the agency and company made a wrong decision to use a new capsule for this mission. SpaceX needed more time than expected to prepare it, and those delays pushed back both the launch of a new crew and the return of the old. So, while everyone is spinning this as SpaceX and NASA brilliantly improvising to get those Starliner astronauts home sooner, the real story is that their return had been significantly delayed by almost two months by SpaceX’s inability to get the capsule ready as promised.

Firefly wins $8.2 million grant from Texas Space Commission

9:36 am

The new Texas Space Commission, established in 2023 by the state legislature and appropriated $350 million to encourage the development of a Texas aerospace industry, has awarded the rocket and lunar lander company Firefly $8.2 million grant.

Firefly said the funding will result in an additional 5,600 square feet of cleanroom space at its 50,000-square-foot spacecraft facility in Cedar Park, as well as added ground and test equipment, a spacecraft pressure proof test facility at the 200-acre campus in Briggs that has 200,000-square-feet of facilities, and upgraded infrastructure for mission operations and labs. The company’s Cedar Park headquarters is 28,000 square feet. The improvements are expected to be completed by the end of this year.

The 50 jobs will be added in engineering, quality assurance, manufacturing and spacecraft operations, according to the announcement. The grant also will enable the company to expand STEM outreach and internship programs, including working with the schools in the University of Texas System to provide hands-on experience in spacecraft development.

Though the commission was given $350 million to help industry, in truth the legislature allocated $200 million of that money to build a new “research and training facility” at Texas A&M. While this might help encourage engineering students to come to Texas and thus settle there within the industry, to me it looks like the commission was mostly created to distribute a very large chunk of cash to this one university.

Orbex scouts Saxaford in advance of first launch

Spaceports surrounding the Norwegian Sea

Though no details have been released, a team from the British rocket startup Orbex has arrived at the Saxaford spaceport in the Shetland Islands to begin preparations for the company’s first launch there, now planned to occur before the end of this year.

Originally Orbex was going to do its launches from the United Kingdom’s other proposed spaceport in Sutherland on the northern coast of Scotland. It had obtained a 50-year-lease to build its own dedicated launch facility, had built its rocket manufacturing facility nearby, and had originally hoped to do the first test orbital launch of its Prime rocket in 2022.

Three years later the UK’s Civil Aviation Authority (CAA) had still not issued Orbex or Sutherland the necessary launch licenses. Faced with bankruptcy if it didn’t launch soon, in December the company announced it was switching its first launch to Saxaford, where the CAA had completed spaceport licensing. It hoped the CAA would thus be able to give it a launch license quickly. We shall see.

Note that the news is slow today. As much as I want to post lots of stuff, I can’t if nothing of significance appears to be happening.

NC State: Maybe rotten to the core
NC State: Maybe it’s rotten to the core

Back in 2021, when I was reporting new blacklist stories every single day during the intolerant madness after the COVID panic and the death of George Floyd, I posted the blacklisting and attempted destruction of a tenured professor at North Carolina State University, merely because Stephen Porter had publicly questioned the wisdom and soundness of its Diversity, Equity, and Inclusion policies.

Though administrators tried hard to push Porter out, he managed to survive, and is still teaching at NC State. Sadly however his attempt for justice failed, his lawsuit against this harassment and slander campaign eventually being dismissed by the courts.

Porter however decided he couldn’t simply close the book on the matter. For example, the leftist effort at NC State to silence all debate during this same time resulted in one university employee committing suicide. He couldn’t take the constant harassment, the doxxing of his home address, the vandalism at his home, and the slanders accusing him of being a racist and “white supremacist” wherever he went on campus, all based on no evidence at all.

Moreover, even though the board of governors of the North Carolina university system in 2023 established an “institutional neutrality” policy that forbid its colleges from requiring new students or faculty to endorse DEI or compel them to obey the pronoun demands of others, Porter kept finding NC State violating that policy, in word and deed.

He decided that he needed to fight back.

China and SpaceX complete launches

12:02 pm

Both China and SpaceX successfully completed launches today.

First, China completed the first launch of its Long March 8A rocket, an upgraded and more powerful version of its Long March 8 rocket. The rocket lifted off from China’s coastal Wencheng spaceport, and put the second batch (number unrevealed) of one of China’s new mega internet constellations.

Along with the basic Long March-8 model and the booster-free tandem configuration, it forms the Long March 8 series of rockets, providing a payload capacity range of 3 tons, 5 tons, and 7 tons to SSO. This significantly enhances China’s satellite networking capabilities for low and medium Earth orbits.

These rockets and the coastal spaceport will also allow China to steadily reduce its reliance on its older family of rockets that use toxic hypergolic fuels and launch from within China.

Next SpaceX launched another 21 Starliink satellites, including 13 with direct-to-cell capabilities, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 18th flight, landing on a drone ship in the Atlantic.

The 2025 launch race:

19 SpaceX
7 China
1 Blue Origin
1 India
1 Japan
1 Russia

Astronomers catalog large ring systems surrounding 74 stars

11:32 am

74 rings surrounding stars
Click for original image.

Using a variety of ground-based telescopes in many wavelengths, astronomers have now produced a detailed catalog of 74 stars with large dust rings similar to the Oort cloud that is believed to exist at the very outer fringes of our own solar system.

The image to the right, reduced to post here, shows all 74 stars.

The new gallery shows a remarkable diversity of structure in the belts. Some are narrow rings, while others are wider and could be categorized more as “disks” than “belts”. Moreover, some of the 74 exocomet systems have multiple rings or disks and some of those are “eccentric,” meaning not a circular orbit but more like an oval. This provides evidence that yet undetectable planets or perhaps moons are present and their gravity affects the distribution of pebbles in these systems.

You can read the paper here [pdf].

The press release implies the discovery of “exocomets” but that is not true. The belts and rings mapped are likely to have comets in them, but no such comets have been found.

The scientists say that this database can be used to better understand the formation of solar systems, though they also admit that the “limited (although much improved) size of our sample” makes any conclusions based on it very uncertain. They hope however that over time that sample size will grow.

A Pakistani rover will fly on China’s Chang’e-8 mission to the Moon

9:18 am

Pakistan and China have finalized plans to place a Pakistani rover on China’s Chang’e-8 lunar lander mission.

This rover partnership was first announced in November 2024. This new release appears to provide a bit more information about the rover itself.

The rover will have a mass of around 35 kilograms and carry science payloads for studying lunar soil composition, radiation levels, plasma properties and testing new technologies for sustainable human presence on the Moon. It will also feature a collaborative scientific payload developed by Chinese and European researchers.

The Chang’e-8 mission is targeting a 2030 launch and will land in the Moon’s south pole region. China also claims it will initiate construction of China’s International Lunar Research Station (ILRS), but that’s a bit of hyperbole. All it shall be is another unmanned lander with two rovers and other instruments, hardly a manned base. What will matter will be what follows, and how quickly.

Blue Ghost leaves Earth orbit

Artist rending of Blue Ghost on the Moon
Artist rending of Blue Ghost on the Moon

Firefly’s Blue Ghost lunar lander has successfully completed the mid-course correction engine burn that has taken it out of Earth orbit and into a transfer orbit to the Moon.

After a successful Trans Lunar Injection burn on Saturday, Feb. 8, Firefly’s spacecraft carrying NASA science and tech to the Moon has departed Earth’s orbit and begun its four-day transit to the Moon’s orbit. Blue Ghost will then spend approximately 16 days in lunar orbit before beginning its descent operations. Since launching more than three weeks ago, Blue Ghost has performed dozens of health tests generating 13 gigabytes of data. All 10 NASA payloads onboard are currently healthy and ready for surface operations on the Moon.

I post the artist’s rendering of Blue Ghost to the right to contrast its design with Intuitive Machines’ Odysseus lunar lander that fell over when it landed last year. Note how much lower to the ground Blue Ghost is. This will certainly reduce the chances it will have the same problem as Odysseus, even if one leg breaks upon landing.
