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
1 Rocket Lab

Watching a Falcon 9 liftoff from an airplane passenger seat

6:01 pm

An evening pause: I think this launch was in December 2022, from Cape Canaveral. Makes a great start for the weekend.

Hat tip Greg the Geologist.

A rose in space

10:02 am

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.

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.

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?

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.”

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.
