The stage will land on a drone ship.
- Blue Origin signs deal with Luxembourg Space Agency to develop a project to map the Moon’s water ice and resources
Like all of Blue Origin’s proposed projects, it is long on pretty graphics and high-minded goals, but short on any specific details.
- China releases an image of its Tianwen-2 asteroid probe on its way to near Earth asteroid 469219 Kamoʻoalewa
It has been in space now for 125 days, and is now about 28 million miles from the asteroid.
- A list showing every delay since Sierra Space’s Dream Chaser was first proposed
Quite disgusting. First proposed in 2007 with a launch promised in 2009, there follows almost two dozen announced delays, steadily pushing the launch back to late ’26, if then.

Cool image at the link. It was the first close look in two decades, since the end of the Galileo orbiter.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
Climategate global-warming activist Michael Mann resigns from PennU after celebrating murder of Charlie Kirk
Climate activist Michael Mann
Though he has claimed to be a climate scientist for decades, Michael Mann at the University of Pennsylvania has been proven time and again to merely be a leftwing global-warming activist, faking data to make it appear the increase of carbon dioxide in the atmosphere is causing global warming, falsely claiming he was a Nobel laureate winner, and acting to destroy the careers of anyone who challenged the veracity of his research.
Sadly, when these facts were discovered almost two decades ago, about the time the climategate emails were released, the climate science community ignored the facts (a very bad thing for scientists to do) and acted to defend Mann. Thus he was able to continue to publish while keeping his job as a professor in academia, first at Pennsylvania State University and then at the University of Pennsylvania.
Mann’s ability to survive fraud and abuse of power however has finally come to an end, and it did so because he decided to go on line after Charlie Kirk was assassinated to joke about that murder and to slander Kirk by reposting comments that called Kirk “head of Trump’s Hitler Youth.”
Though Mann subsequently denied that was what he was doing, deleting some of his worst tweets while claiming to condemn such violence, it appears no one believes him. As a result, he announced yesterday that he resigning his position at Pennsylvania University in order to become a full time political activist. From his resignation statement:

The growing mystery of the little red dots in the early universe
The uncertainty of science: A review of the population of what scientists call “Little Red Dots” (LRDs) — discovered in the early universe by the Webb Space Telescope — has found that 30% do not appear to be compact objects when viewed in ultraviolet wavelengths.
The team studied 99 LRDs, and found that about 30% are not simply compact dots when observed in the ultraviolet.Instead, they reveal disturbed or clumpy structures, in stark contrast to their smooth, point-like appearance at optical wavelengths. Because these galaxies are so far away, their optical light is stretched, or “redshifted,” into the long-wavelength channel of JWST, where the resolution is not sharp enough to see structure, so they look like simple dots.
Rinaldi: ‘But their ultraviolet light is shifted into JWST’s short-wavelength channel, where the telescope has much finer resolution, and there we suddenly see clumps, asymmetries, and signs of interaction. On top of this, in the spectra of some of our LRDs we directly detect the fingerprints of active black holes, with gas moving at thousands of kilometres per second.’ This shows that at least part of this population is powered by growing black holes, while others seem to be dominated by star formation, making LRDs a mixed and diverse family of sources. This is a crucial clue, suggesting that mergers and galaxy interactions may be the trigger for the “LRD phase”.
In other words, astronomers don’t really know what these dots are at present. If some are supermassive black holes, this poses a problem for Big Bang cosmology, as there should not have been enough time since the Big Bang for these black holes to have formed.
That 70% still appear to be compact single objects might mean that’s what they are, but it could also mean that our present observations tools don’t yet have the ability to resolve them.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

Analysis of archived Cassini data finds a new slate of carbon-based molecules in the plumes of Enceladus
The tiger strip vents on Enceladus, seen
from 77 miles during 2015 fly-by. Resolution is
50 feet per pixel.
A new analysis of the archived Cassini data taken when the spacecraft flew through the plumes of the Saturn moon Enceladus in 2008 has revealed a number of new organic molecules (not life but carbon-based) that suggest the chemistry of the moon of Saturn is far more complex that expected.
You can read the paper here. From the abstract:
Here we present a comprehensive chemical analysis of organic-bearing ice grains sampled directly from the plume during a Cassini fly-by of Enceladus (E5) at an encounter speed of nearly 18 km [per second]. We again detect aryl and oxygen moieties in these fresh ice grains, as previously identified in older E-ring grains. Furthermore, the unprecedented high encounter speed revealed previously unobserved molecular fragments in Cosmic Dust Analyzer spectra, allowing the identification of aliphatic, (hetero)cyclic ester/alkenes, ethers/ethyl and, tentatively, N- and O-bearing compounds. These freshly ejected species are derived from the Enceladus subsurface, hinting at a hydrothermal origin and involvement in geochemical pathways towards the synthesis and evolution of organics.
In other words, this data further suggests there exists an underground ocean inside Enceladus, and that ocean has a lot of complex organic chemistry energized by the planet’s internal heat and the tidal forces imposed by Saturn’s gravity.
This is not the first time scientists have reviewed archived Cassini data of these plumes and found new molecules. It is simply a closer look at earlier analyses in 2018 and 2019.
This data has not discovered life, but it suggests that life is certainly possible within that proposed underground ocean. At a minimum, the chemistry there will be very complex and alien.
Astronomers snap picture of a baby exoplanet
Click for original image.
Cool image time! The picture to the right, cropped to post here, was taken using Magellan Telescope in Chile and the Large Binocular Telescope in Arizona. The exoplanet is the small purple dot to the right of the star and the accretion ring that surrounds it.
This exoplanet is very young, only about five million years old, and is thus still accumulating material. Even so, its mass is presently estimated to be five times that of Jupiter.
Following [the first] observations of the system, researchers looked at WISPIT 2, and spotted the planet WISPIT 2b for the first time, using the University of Arizona’s MagAO-X extreme adaptive optics system, a high-contrast exoplanet imager at the Magellan 2 (Clay) Telescope at Las Campanas Observatory in Chile. This technology adds another unique layer to this discovery. The MagAO-X instrument captures direct images, so it didn’t just detect WISPIT 2b, it essentially captured a photograph of the protoplanet.
…In addition to discovering WISPIT 2b, this team spotted a second dot in one of the other dark ring gaps even closer to the star WISPIT 2. This second dot has been identified as another candidate planet that will likely be investigated in future studies of the system.
You can read the paper here [pdf]. The other candidate exoplanet is the bright spot below the star, inside the ring.
The technology of astronomy continues to advance.

International Astronautical Congress meeting in Australia produces several international agreements
During the International Astronautical Congress meeting that is going on in Sydney, Australia this week, a number of countries have signed agreements calling for a variety of partnerships.
- NASA signs US-Australia Agreement on Aeronautics, Space Cooperation
- Australian and Japanese organizations join forces on optical communications
- European Space Agency and Korea AeroSpace Administration embark on new cooperation
- Australia and UK extend Space Bridge partnership
None of the agreements appear to include any significant new projects. All suggest a desire to work together to foster development in their commercial space industries. The number of agreements with Australia is a reflection of the conference’s location in Sidney.
The most amusing agreement is the last, between the UK and Australia. The governments of both of these Commonwealth nations have had serious problems with red tape that have hindered commercial development, especially in the UK. The agreement expands a UK government grant program worth about $9 million so that Australian startups can win grants. It apparently does nothing to ease the red tape in either nation.
Varda signs deal for more capsule landings in Australia
Australian spaceports: operating (red dot) and proposed (red “X”)
Click for original image.
The recoverable capsule company Varda has now signed a new deal that will allow it to land up to 20 more capsules at the commercial spaceport/range Southern Launch in Australia through 2028.
It has already landed capsules there twice. This new contract suggests that Varda has enough expected customers and products to place in its capsules to pay for about six or seven capsules launched per year. If so, this manufacturing model in space is going to bloom very quickly, and will likely become a major profit center for the commercial space stations now under development.
The deal also illustrates the utter failure of the U.S. government’s red tape, especially during the Biden administration.
The company landed its first mission, W-1, at the Utah Test and Training Range in February 2024. But difficulties securing licenses and other approvals for that mission prompted Varda to look elsewhere. “Through that experience, it became pretty clear that the U.S. was not going to be the location for high-cadence reentry operations in the near term,” Eric Lasker, Varda’s chief revenue officer, said at an IAC event announcing the new agreement.
Hopefully the anti-regulatory policies of Trump will change this, but for the moment our government has driven this American company away from the U.S.
Belgium company joins Starlab space station consortium

The Starlab consortium, proposing to build its single-module large Starlab space station that will be launched on Starship, has now added the Belgium company Space Applications Services (SpaceApps) as both a partner and investor.
SpaceApps contributes deep experience in space systems, mission operations and payload integration with capabilities that include avionics, payload development, the end-to-end International Commercial Experiment Cubes (ICECubes) service, as well as mission integration and operations control software. The company also works closely with the European Space Agency and international partners, broadening Starlab’s access to global markets and research communities.
The Starlab consortium already includes the American companies Voyager Space and Northrop Grumman and the European company Airbus. It also has a partnership agreement with the European Space Agency. This new Belgium partnership further cements its place as Europe’s potential future space station after ISS is retired.
This deal is only one of several news stories in the past week signaling progress by this consortium. It has signed the American company Vivace to build the station’s main structure and its partner Northrop Grumman has successfully tested the rendezvous and docking technology its Cygnus cargo capsule will use to dock with Starlab. All in all this station appears to be assembling the pieces its needs.
Below is my updated rankings of the four commercial stations under development:

Axiom successfully tests two of its lunar spacesuits underwater
Axiom’s two spacesuits being tested underwater.
Click for original.
The space station startup Axiom this week successfully completed underwater testing of two of its lunar spacesuits, making them ready for astronaut training.
Axiom won the contract to build these suits for NASA in 2022. It speaks well of the company that only three years later the suits are now ready for use. It also shows NASA’s own incompetence, because before it awarded this contract to Axiom the agency tried to build its own suits, spending more than a billion dollars and fourteen years to produce nothing.
Furthermore, this success underlines yesterday’s NASA inspector general report that lambasted Collins Aerospace’s incompetence in maintaining the spacesuits on ISS. Collins in 2022 had won a similar spacesuit contract to build new space station suits, but two years later backed out of the deal, unable to get the job done.
For Axiom, this spacesuit success adds an essential component to its own space station plans. Though these suits are intended for the Moon, the company now has the basics down for its own space station suit. It owns this suit design, and will not only sell suits to NASA, it can market the suits to any one else.
