”The Smithsonian estimates that transporting Discovery from Virginia to Houston could cost more than $50 million, with another $325 million needed for planning, exhibit reconstruction, and new facilities. These costs far exceed the $85 million appropriated in the One Big Beautiful Bill Act, P.L. 119-21. Dedicating hundreds of millions of taxpayer dollars to move an artifact that is already housed, displayed, and preserved in a world-class facility is both inefficient and unjustifiable.”
-Statement in an October 23, 2025 bipartisan letter from the US Senate Committee on Appropriations. In addition to the cost, the letter also highlights potential damage to the shuttle, stating:
Moving the shuttle would inevitably and irreparably compromise the artifact and render it unusable as a museum-quality collection item, permanently diminishing its historical and cultural value for future generations.
Applying a principle of “radical mundanity”, this paper examines explanations for the lack of strong evidence for the presence of technology-using extraterrestrial civilizations (ETCs) in the Galaxy – the Fermi paradox. With this principle, the prospect that the Galaxy contains a modest number of civilizations is preferred, where none have achieved technology levels sufficient to accomplish large-scale astro-engineering or lack the desire to do so. This consideration also leads to the expectation that no ETC will colonize a large fraction of the Galaxy, even using robotic probes, and that there are no long-duration high-power beacons. However, there is a reasonable chance that we may make contact on a short, by historical standards, timescale. This event would be momentous, but could still leave us slightly disappointed. Such a Universe would be less terrifying than either of the two possibilities in the quote generally attributed to Arthur C. Clarke on whether we are alone or not. Also, if there is a modest number of ETCs in the Galaxy, that would suggest that there is a large number of planets with some form of life.

This week’s image highlights a NASA poster that you can download (in a variety of versions). It shows the Cat’s Paw Nebula (NGC 6334) as captured by the James Webb Space Telescope (JWST).
Here is a short summary of what you are seeing from NASA:
Located approximately 4,000 light-years away in the constellation Scorpius, the Cat’s Paw Nebula offers scientists the opportunity to study the turbulent cloud-to-star process in great detail. Webb’s observation of the nebula in near-infrared light builds upon previous studies by NASA’s Hubble and retired Spitzer Space Telescope in visible- and infrared-light, respectively.
With its sharp resolution, Webb shows never-before-seen structural details and features: Massive young stars are carving away at nearby gas and dust, while their bright starlight is producing a bright nebulous glow represented in blue. It’s a temporary scene where the disruptive young stars, with their relatively short lives and luminosity, have a brief but important role in the region’s larger story. As a consequence of these massive stars’ lively behavior, the local star formation process will eventually come to a stop.

The U.S. has plenty of issues regarding the pace of its space programs in the face of Chinese achievements, as noted multiple times in posts on this site. We should not see this as anything new. U.S. politicians and citizens had plenty of similar complaints during the space race with the USSR, and we also have evidence of similar complaints within the USSR.
For instance, on this day in 1965, Yuri Gagarin, the first man in space, wrote a letter with other cosmonauts to the USSR’s General Secretary Brezhnev with a list of concerns. The letter stated, in part:
The USA have not only caught up with us, but even surpassed us in certain areas. The flights of space vehicles Ranger-7, Ranger-8, Mariner-4, Gemini-5, and others are serious achievements of American scientists. This lagging behind of our homeland in space exploration is especially objectionable to us, cosmonauts, but it also damages the prestige of the Soviet Union and has a negative effect on the defense efforts of the countries from the socialist camp…Why is the Soviet Union losing its leading position in space research? A common answer to this question answer is as follows: the USA have developed a very wide front of research in space; they allocate enormous funds for space research. In the past 5 years they spent more than 20 billion dollars, and in 1965 alone 7 billion dollars. This answer is basically correct. It is well known that the USA spend on space exploration much more than does the USSR.
The letter covers other issues, including battles between the various organizations involved in space affairs as well as a stated preference by some for robotic flights rather than manned-flights.
It is an interesting reminder that the same issues constantly crop up to potentially cripple space initiatives, and today’s leader in space can quickly fall behind.
Earth has received a new cosmic partner, a small asteroid designated as 2025 PN7. NASA confirmed this week that the object, initially found by the University of Hawaii, qualifies as a “quasi-moon” , an uncommon type of celestial body that moves almost similarly in sync with Earth. While not a real moon, it has a similar orbit surrounding the Sun, seeming to shadow our planet as it travels through space. Researchers estimate the asteroid measures 18 to 36 meters wide, approximately the height of a small building, making it small by cosmic standards but noteworthy for Earth’s extended neighborhood.
Twenty years after the Cassini spacecraft discovered an ocean under the icy surface of Saturn’s moon Enceladus, a new study of previously collected data hints at a much better chance for habitability. The change comes from recording how a plume of ice grains hit Cassini just minutes after it erupted from the moon. The close encounter exposed organic compounds not previously seen on Enceladus.
Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious Martian dune gullies. Earth scientist Dr Lonneke Roelofs from Utrecht University has investigated how these gullies were formed. In a test setup, she observed that blocks of CO2 ice ‘dug’ these gullies in a unique way. “It felt like I was watching the sandworms in the film Dune.”
