One of China’s big satellite constellations appears in trouble

9:35 am

According to a report in China’s state-run press today, one of the giant satellite constellations China is building to compete with SpaceX’s Starlink constellation is in trouble, and will likely fail to meet its international licensing requirement to place more than six hundred satellites in orbit by the end of 2025.

Only 90 satellites have been launched into low Earth orbit for the Qianfan broadband network – also known as the Thousand Sails Constellation or G60 Starlink – well short of the project’s goal of 648 by the end of this year.

Under international regulations to prevent spectrum hoarding, satellite operators must deploy a certain proportion of their constellation within set times after securing orbits and radio frequencies.

Shanghai Yuanxin Satellite Technology, the company leading the project, plans to deploy more than 15,000 satellites by 2030 to deliver direct-to-phone internet services worldwide.

To meet its license requirement, it require a launch pace for the rest of ’25 of about 30 satellites per month, something that the article says is unlikely due to “a severe shortage of rockets” in China.

This story might also explain why China’s government yesterday ordered all its rocket pseudo-companies to speed up their test schedules, pushing to launch their new rockets for the first time this year instead of in 2026. The Xi government’s order appears to be trying to address this rocket shortage.

Senegal to sign Artemis Accords

9:24 am

According to a NASA announcement today, Senegal will become the 56th nation to sign Artemis Accords tomorrow.

The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

It remains unclear whether the second Trump administration has taken a new interest in using this alliance to renew the accords’ original goals, of encouraging private enterprise and property rights in space. The Biden had shifted the purpose away from those goals towards the more globalist approach represented by the Outer Space Treaty.

Trump administration moving to reduce rocket launch environmental regulations

9:16 am

FAA logo

According to a draft executive order that has not yet been released, the Trump administration is planning a major revision of the FAA’s environmental and launch regulations that has badly impacted rocket companies, with the goal of streamlining licensing.

The order would give Trump even more direct control over the space industry’s chief regulator by turning the civil servant position leading the FAA’s Office of Commercial Space Transportation into a political appointment. The last head of the office and two other top officials recently took voluntary separation offers.

The order would also create a new adviser to the transportation secretary to shepherd in deregulation of the space industry.

…The draft order also seeks to restrict the authority of state coastal officials who have challenged commercial launch companies like SpaceX, documents show. It could lead to federal officials interfering with state efforts to enforce their environmental rules when they conflict with the construction or operation of spaceports.

The order would also have the secretary of transportation ‘reevaluate, amend, or rescind’ sections of Part 450, the FAA licensing regulations that it imposed during the Biden administration that was supposed to streamline licensing but ended up adding considerable new red tape which contributed significantly to squelching the new launch industry that had popped up during the first Trump term.

As is usual for the propaganda press, the article at the link implies that these changes would result in horrible environmental consequences as well as increased safety risks to the public. What it does not note is that these changes appear to simply return the regulatory framework back to what existed prior to the Biden administration, a framework that had existed for more than a half century previously. The environment and public safety did just fine under those more freedom-oriented rules. I am sure both will do just fine again.

This order might also help explain Trump’s decision to withdraw Jared Isaacman as NASA administrator and appoint Transportation Secretary Sean Duffy as interim NASA administrator. The order puts much of this work on his head, and having him in charge of NASA will likely aid that work.

First Hubble images of interstellar comet 3I/Atlas released

5:03 pm

Comet 3I/Atlas, taken by Hubble
Click for original.

An undergraduate student has just released the first pictures taken by the Hubble Space Telescope of the interstellar object 3I/Atlas, confirming that it is a comet as indicated by the earlier image taken by the Gemini North telescope.

One of those images, taken only hours ago, is the inset on the map showing the comet’s route through the solar system to the right. The streaks on the image are either stars or cosmic rays. Though this image is of significantly lower quality than the Gemini North picture, it once again shows both the comet’s nucleus and developing coma.

A preprint [pdf] of a new research paper based on data from both telescopes further confirms this conclusion:

[T]hese results suggest that 3I/ATLAS hosts a coma containing large water ice grains, and that its dust continuum is stable over at least week-long timescales. The spectral characteristics further distinguish 3I from known ultrared trans-Neptunian objects and align it more closely with active Jupiter-family comets.

The last conclusion is very significant. Though the path and speed of this interstellar object says it must come from beyond the solar system, its cometary make-up more resembles comets that reside in the inner solar system. These facts strongly imply that there is at least one other solar systems not very different from our own.

SpaceX launches two SES communications satellites

2:41 pm

Despite a launch abort yesterday at T-11 seconds for unstated reasons, SpaceX followed up by successfully completing the launch today, sending two SES communications satellites into orbit with its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

This was SpaceX’s fifth launch for this SES constellation, during which it has placed a total of ten satellites into orbit. The first stage completed its sixth flight, landing on a drone ship in the Atlantic. The fairings completed their ninth and twenty-first flights respectively.

A few hours earlier a different SpaceX rocket had another launch abort at about T-43 seconds, this time because of a local power outage. That launch has been rescheduled for later this evening.

The leaders in the 2025 launch race:

90 SpaceX
37 China
10 Rocket Lab
8 Russia

SpaceX now leads the rest of the world in successful launches, 90 to 64.

Astronomers detect exoplanet shaping the protoplanetary disk surrounding a baby star

9:41 am

Star with disk
Click for original image.

Astronomers using two different instruments on the Very Large Telescope (VLT) in Chile have now directly detected what they think is an exoplanet as it shapes the spiral arms of a baby star’s protoplanetary disk.

In the case of HD 135344B’s disc, swirling spiral arms had previously been detected by another team of astronomers using SPHERE (Spectro-Polarimetric High-contrast Exoplanet REsearch), an instrument on ESO’s VLT. However, none of the previous observations of this system found proof of a planet forming within the disc.

Now, with observations from the new VLT’s Enhanced Resolution Imager and Spectrograph (ERIS) instrument, the researchers say they may have found their prime suspect. The team spotted the planet candidate right at the base of one of the disc’s spiral arms, exactly where theory had predicted they might find the planet responsible for carving such a pattern.

The newly detected object however might be a brown dwarf and not an exoplanet. More observations are required to reduce the uncertainty.

Have astronomers observed a black hole twice gobble from the same star?

9:23 am

Astronomers have now observed identical flares 700 days apart and coming from the same supermassive black hole, suggesting that a star was partially disrupted both times as it orbited the black hole.

Both flares produced less energy than predicted, based on calculations that assumed the complete destruction of a star. From the paper’s [pdf] abstract:

Here we present the optical-ultraviolet tidal disruption event AT 2022dbl, which showed a nearly identical repetition 700 days after the first flare. Ruling out gravitational lensing and two chance unrelated disruptions, we conclude that at least the first flare represents the partial disruption of a star.

…Since both flares are typical of the optical-ultraviolet class of tidal disruptions in terms of their radiated energy, temperature, luminosity, and spectral features, it follows that either the entire class are partial rather than full stellar disruptions, contrary to the prevalent assumption, or some members of the class are partial disruptions, having nearly the same observational characteristics as full disruptions. Whichever option is true, these findings could require revised models for the emission mechanisms of optical-ultraviolet tidal disruption flares and a reassessment of their expected rates.

Assuming the star wasn’t completely destroyed during the second flare, a third flare should occur about two years from now, as the star swings around and makes its next close approach. If so it will confirm this theory. If not, we will be left with the simple uncertainty of science.

Local county abruptly stops delivering water to Boca Chica

9:04 am

Without any warning Cameron county early this month abruptly stopped its decades-long delivery of water to residents of Boca Chica and the newly formed town of Starbase.

[T]he county suddenly stopped the $15 monthly service — with no notice — earlier this month, said Keith Reynolds, a Starbase resident unaffiliated with SpaceX.

“Abruptly cutting off water service without notice poses safety and public health risks,” Kent Myers, Starbase’s city administrator, wrote in a letter to County Commissioner Sofia Benavides, whose precinct includes that stretch of Texas 4. Starbase, he pointed out, “has neither the legal authority nor operational capacity to deliver water to these residents.”

Neither the county nor Commissioner Benavides has responded to multiple requests for comment about the decision. Reynolds said the county and Benavides “decided to leave everybody high and dry without water — didn’t say a word.”

…Reynolds, who’s had his troubles with his SpaceX neighbors over the years — including power surges, traffic, drones and behavior he’s described as bullying, said the county’s recent move bothers him more than anything SpaceX has done. “That’s just a willful denying of basic services to your residents,” he said. “You can’t just stop being a provider of water for a whole community.”

The county’s action including cutting off service to residents both inside Starbase and those nearby.

SpaceX has been topping off residents tanks for the time being at no charge. It is in the process of establishing its own water system, but for these locals to access it will require them to sign agreements that require them to evacuate during launches if ordered to by SpaceX.

The lack of explanation or warning strongly suggests the county’s actions were a political retaliation against the recent creation of the town of Starbase. County Commissioner Benavides had previously opposed the recently passed state law that gave Starbase the power to close Boca Chica’s beaches.

A galaxy surrounded by galaxies

11:12 am

A galaxy surrounded by galaxies
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a survey of galaxies where Type 1a supernovae have occurred, in order to better refine the precise brightness of these explosions.

What makes this galaxy most interesting are the hundreds of other galaxies that appear to surround it. And that ain’t an illusion.

NGC 3285B is a member of the Hydra I cluster, one of the largest galaxy clusters in the nearby Universe. Galaxy clusters are collections of hundreds to thousands of galaxies that are bound to one another by gravity. The Hydra I cluster is anchored by two giant elliptical galaxies at its centre. Each of these galaxies is about 150,000 light-years across, making them about 50% larger than our home galaxy, the Milky Way. NGC 3285B sits on the outskirts of its home cluster, far from the massive galaxies at the centre.

As for the survey program, Type 1a supernovae are the measure cosmologists have used to discover the unexpected acceleration of the universe’s expansion rate at the largest scales, something they dub “dark energy” because they really don’t understand what they have discovered. That discovery however hinges entirely on the assumed intrinsic brightness of Type 1a supernovae. Astronomers have assumed these supernovae all have the same approximate brightness, and extrapolate their distance by that brightness.

The problem are the assumptions. We really don’t know if all Type 1a supernovae are approximately the same brightness. And even if they are equally bright, we also do not have a firm grasp of what that brightness should be.

This survey is an attempt to narrow or eliminate these uncertainties.

Government employees: The most spoiled and privileged individuals on Earth

9:50 am

NASA: home to the privileged and perfect
NASA: home to the privileged and perfect

Timed to coincide with the anniversary of the Apollo 11 lunar landing, NASA employees and many of their supporters gathered yesterday for protests, demanding that their jobs be saved and that Congress not only cancel Trump’s proposed budget cuts to NASA, that Congress even consider increasing the budget because the work they do is so so SO vital.

The protests appeared to be organized by several groups, all claiming to be “grassroots” but all seeming to be well funded and comparable to other recent government protest groups at other agencies, issuing sanctimonious “declarations” that claim the cuts “to waste public resources, compromise human safety, weaken national security.”

Yet, the Trump cuts would only reduce NASA’s staffing of 17,000 by about 2,600 employees. How horrible!

This quote from the first link above is typical of the attitude of these government workers:

Is SpaceX doing ocean salvage operations near Boca Chica?

11:25 pm

Superheavy aft section being salvaged
Click for original source.

SpaceX appears to be recovering the Superheavy booster that soft landed off shore from Boca Chica during the sixth test flight in November.

On Saturday, footage, albeit from a vantage point of someone who should not have been that close to the recovery operations, showed the aft end of a Booster with most of its Raptor engines still attached, being lifted out of the water.

During that November flight mission controllers decided against attempting a chopstick recovery, and sent the booster to do a soft vertical spashdown just off the coast. The booster than fell over and was seen drifting south. It appears SpaceX has now mounted operations to recovery it, possibly in response to the complaints by Mexican officials about its rocket pieces showing up on the beaches. Company engineers likely also wish to take a look at the equipment for their own reasons.

2016 documents now prove Obama and his top intelligence officials conspired to create the Russian collusion hoax

1:15 pm

Evidence Obama conspired to overthrow Trump
Click for full graphic.

Treason: Documents now released from 2016, just after Trump’s election victory, prove without doubt that Obama and his top intelligence officials conspired to create Russian collusion hoax, despite having assessments by their intelligence agencies declaring Russian actions did not include Trump and had no impact at all on the 2016 election.

That assessment is nicely summarized by the screen capture to the right.

We assess that Russian and criminal actors did not impact recent US election results by conducting malicious cyber activities against election infrastructure.

After getting that negative assessment, Obama immediately called a meeting to rewrite the conclusions, in order to create a fake political issue aimed directly at destroying Trump’s presidency.
