An evening pause: Worth watching, though this underground telescope won’t be operational any earlier than 2032, and considering the present political situation related to government funding, it might never get finished at all.

Echostar has awarded the satellite company MDA Space a $1.3 billion contract to build the first 100 satellites in its proposed direct-to-phone constellation that will compete directly with the constellations of SpaceX’s Starlink and AST SpaceMobile.
The initial contract, valued at approximately US$1.3 billion (approx. C$1.8 billion), includes the design, manufacturing and testing of over 100 software-defined MDA AURORA™ D2D satellites. With contract options, enabling a full initial configuration of a network of over 200 satellites, the value of the contract would increase to an approximate total value of US$2.5 billion (approx. C$3.5 billion). EchoStar envisions future growth to thousands of satellites, as demand requires, to provide global talk, text and broadband services directly to standard 5G handheld devices.
The constellation will be fully compliant with the newly created NTN and 3GPP standards, allowing EchoStar to provide messaging, voice, broadband data, and video services upon launch to all phones configured to this standard, without modifications. Additionally, the constellation will connect to an array of sensor and mobile vehicles.
All three constellations are designed to provide cell service in areas where there are no cell towers. The satellites themselves become the cell towers, in orbit.
Since most people today access the internet via their smartphones, I can see these direct-to-phone constellations eventually becoming the prime method for accessing the web. Why have a separate provider for your web services when these constellations can give you that as well as phone service. It is for this reason I suspect Echostar is jumping on the bandwagon.
This move also suggests the older Starlink and Kuiper constellations, that only provide web service, are going to eventually get superseded. For Starlink this isn’t really a threat, as it is already beginning the transition to this new technology and can likely shift its millions of customers to it easily when the time comes. For Amazon’s Kuiper constellation, however, it appears it might be arriving too late in the game.
More proof that in capitalism speed is essential. Amazon has simply moved too slowly in launching its constellation.

Roscosmos: a paper tiger
A string of short articles in Russia’s state-run press today, describing the meetings between the head of Roscosmos, Dmitry Bakanov, and interim NASA administrator Sean Duffy, suggest strongly that Russia is desperate to link itself with someone in order to continue its generally bankrupt space program.
Bakanov is making his first visit to the U.S. He and Duffy are also conducting the first face-to-face talks by the heads of their respective agencies in eight years. While the U.S. press has been entirely uninterested in these discussions, mostly because it knows little of substance will come of them other than an agreement to maintain the partnership at ISS through its planned retirement in 2030, the reaction by Russia’s press has been remarkably fawning, repeatedly proposing the U.S. and Russia expand their partnership beyond ISS:
Very clearly, Bakanov was trying to convince Duffy to consider a greater partnership, whereby Roscosmos and NASA do other space projects together. He might have even been offering to join NASA’s Artemis program to explore the Moon.
It appears from the other Russian state-run reports, however, that Duffy’s response was diplomatic but unenthused by such a proposal. All he apparently agreed to was to continue the ISS partnership, until the station’s retirement.

SpaceX’s Endeavour Dragon capsule has been successfully placed in orbit carrying four astronauts to ISS, its Falcon 9 rocket lifting off from Kennedy in Florida.
This is Endeavour’s sixth flight. It will dock at ISS in the early hours tomorrow. The first stage completed third flight, landing back in Florida.
The leaders in the 2025 launch race:
96 SpaceX
41 China
10 Rocket Lab
9 Russia
SpaceX now leads the rest of the world in successful launches, 96 to 71.
An evening pause: Hat tip Wayne DeVette, who notes, “The band’s name comes from a photo of W.C. Fields in Kenneth Anger’s book Hollywood Babylon, which bore the caption ‘W.C. Fields with gin blossoms’, referring to the actor’s telangiectasia-spotted face and rhinophymic nose by the slang term for the skin condition known as rosacea.”
Only a few hours after it scrubbed the launch of its Endeavour capsule carrying four astronauts to ISS because of weather at Kennedy in Florida, SpaceX proceeded to successfully launch 19 more Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.
The relatively low number of Starlink satellites on this launch appears related to the higher orbit in which they were placed. The first stage completed its 27th flight, landing on a drone ship in the Pacific. SpaceX now has four boosters that have flown more than 25 times, respectively 29, 27, 26, and 26.
The leaders in the 2025 launch race:
95 SpaceX
41 China
10 Rocket Lab
9 Russia
SpaceX now leads the rest of the world in successful launches, 95 to 71. Meanwhile, the manned Endeavour launch has now been rescheduled for tomorrow morning.

The uncertainty of science: Using new data from the Webb Space Telescope, scientists now conclude that the identification on an exoplanet in April 2025 of the molecules dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS) — both of which on Earth are only associated with the presence of life — is now uncertain and that these molecules likely aren’t there.
The new work uses [Webb] data to better qualify what is going on. The work confirms the presence of an ocean on this peculiar exoplanet, although it can’t confirm if there is a thick or thin atmosphere. They couldn’t find water vapor in the atmosphere, suggesting that there is an efficient cold trap, keeping evaporation to a minimum on this temperate sub-Neptune world.
Those potential biosignatures were all below the threshold for an undeniable detection, and their model suggests that a possible presence of DMS could be explained by sources unrelated to life. They advise considering more and different molecules to use as biosignatures. Astronomers are studying worlds that are very different from our own, and the chemical signatures that seem obvious here on Earth might not fit well with those exoplanets.
In other words, they simply don’t have enough data to know, one way or the other. No surprise, The science of studying exoplanets is in its infancy, and right now can only tease out the smallest of details based on our limited technology and the distances involved.
You can read the new paper here [pdf]. It notes further that using these molecules as a sign of life is also a mistake, as they can be created in other ways having nothing to do with biology.
Artemis, a program based on fantasy
Increasingly it appears everyone in Congress, the White House, and NASA, as well as our bankrupt mainstream press, has become utterly divorced from reality in talking about NASA’s Artemis lunar program. The claims are always absurd and never deal with the hard facts on the ground. Instead, it is always “Americans are piorneers! We are great at building things! We are going to beat China to the Moon!”
An interview of interim NASA administration (and Transportation secretary) Sean Duffy yesterday on the Sean Hannity Show made all these delusions very clear. First Hannity introduced Duffy by stating with bald-faced ignorance that “NASA has a brand-new program. It is called Artemis that aims to get astronauts back on the Moon in the next couple of years.”
I emphasize “brand-new” because anyone who has done even two seconds of research on the web will know that Artemis has existed now for more than a decade. Hannity illustrates his incompetence right off the bat.
Duffy then proceeds to insist that the next Artemis mission, dubbed Artemis-2, will fly in April 2026 and send four astronauts around the Moon, followed by the Artemis-3 manned landing one year later.
Being an incompetent member of the propaganda press, Hannity of course accepts these claims without question. He fails to question Duffy about the serious issues with the Orion heat shield, which experienced extensive unexpected damage that is still not understood during its return on the first Artemis mission in 2022.
Nor does either Duffy or Hannity mention the fact that for Artemis to land humans on the Moon SpaceX’s Starship not only has to become operational for human passengers, it needs an in-orbit refueling capability that does not yet exist. I have full confidence that SpaceX will eventually succeed in achieving these benchmarks, but I also doubt it will be able to do it by mid-2027, as claimed by Duffy.
Duffy and Hannity however are not alone in living in this dream world. » Read more
The California Coastal Commission has now scheduled a meeting on August 14, 2025 to reconsider SpaceX’s request to double its launch rate at Vandenberg Space Force Base from 50 to 100 launches per year.
Though it has no real authority over the base, and though the Space Force has indicated it has no objections to SpaceX’s proposal, the commission rejected that increase in a 6-4 vote in October 2024, but did so not because the commissioners thought it would harm California’s beaches, but because they did not like Elon Musk’s endorsement and campaigning for Donald Trump during the election campaign.
SpaceX has subsequently sued, with a judge ruling two weeks ago that the suit can go forward. Based on the statements made by commissioners in October, SpaceX has an excellent case, and will likely win in court.
It appears the commission is now acting to possibly stave off that suit. The article at the link also notes that the make-up of the commission has changed since that October meeting, with at least one of the commissioners who expressed the most hate against Elon Musk, Gretchen Newsom, is no longer a member.
At the same time, the hostility to Musk and SpaceX for environmental reasons appears to still exist within the commission. Either way, in the end SpaceX’s launch rate at Vandenberg is going to increase, since the military is agreeable to the change.
According to a report in Russia’s state-run press today, the repairs to the air leak in the Russian Zvezda module on ISS have reduced the rate of air lose significantly, but have failed to eliminate it.
Long-term observations have shown that the leak in the interstitial chamber of the Zvezda module of the International Space Station, which was reported to have been fixed in June, is still ongoing, though its rate has slowed significantly, Roscosmos Executive Director of Manned Space Programs, special presidential envoy for international space cooperation Sergey Krikalyov said.
“The leak is ongoing. We continue our efforts to find and fix it, with the recent repairs having seriously reduced the rate of air leakage. For some time we even thought that we had found the last crack and sealed it, though long-term observations have shown that it (air loss – TASS) continues,” he told a press conference ahead of the launch of the Crew Dragon Endeavour spacecraft carrying the Crew-11 mission crew.
Even if Russia succeeds eventually in sealing the leak entirely, this does not solve a more fundamental problem, the existence of stress fractures in the hull of Zvezda that have caused the leaks. That module, built in the 1990s and the second oldest module on ISS, remains at serious risk of catastrophic failure due to these fractures. That the leak has not yet been sealed suggests that new cracks are steadily forming even as Russian astronauts patch older cracks.
Though they do not say so, officials at both Roscosmos, NASA, and their partners in Europe and Japan are all praying that the station can last until 2030, when they plan to retire and de-orbit it. They all know however that there is a great risk that Zvezda will not cooperate, and cause an unplanned shut down much earlier.
