A rose in space

A rose in space

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.”
