NOTE: I offer a bit of a riff about the rarity of science - not just on Earth but possibly across the cosmos - at the end.
We are gadually trying to resume 'normal' life after our family suffered a 'disruption' in our living arrangements that has left us frazzled, with little time for blog updates. But things are a bit better now, so here is... a roundup of recent* space news and updates.
*(Well, 'recent' as of when these postings were actually drafted, in January, before we realized how crazy things were gonna get!)
== Heading for the moon ==
Sending landers to the lunar surface: In mid-January, a SpaceX Falcon 9 rocket launched two commercial landers - Firefly Aerospace's Blue Ghost lander and Japan's ispace's Resilence lander - to the moon.
The landers contain scientific instruments to analyze the lunar regolith and magnetosphere, and set up a moon-based global navigation system, laying the groundwork for future lunar missions.
*As of March 30... well... any space junkies know how it went.
== Rogue planets all over! ==
One of the imperfectly insufficient (by itself) but substantially plausible theories for the Great Silence or “Fermi Paradox” (terrible name) is that interstellar travel… even at just 10% of light speed… is made very difficult by a minefield of hidden obstacles. No, I am not talking about my short story “Crystal Spheres.” But rather, these would be rogue planets that are untethered from stars. Every year we find they are more common in the galaxy.
For example, the infrared-sensitive Webb Telescope has found hundreds… down to Saturn size, just in the Orion Nebula, alone! Forty-two of them are in binary pairs. Wow. Implicit: billions of free-floating planets in the darkness between the stars.
One more incredible accomplishment by this fantastic instrument that this fantastic, scientific civilization created, in our steady and accelerating progress as apprentices in the Laboratory of Creation!
And yet some ignore the almost (or actual) theological significance of these incredible accomplishments (Robots roaming Mars! New human-made life forms! The new skills to save this beautiful world from … ourselves!) Okay, grad students in Creation’s Lab should respect those who clutch the Kindergarten text given to illiterate shepherds. Fine.
But those who wage all-out war vs science are clearly the real heretics, here.

== Monitoring Methane Emissions ==
Among the worst criminals alive today are those who are deliberately venting methane into the atmosphere. After GOP Congresses deliberately canceled or slashed the satellites to track down vents and Trump delayed them, we now, at last, have the policing tools. A satellite that measures methane leaks from oil and gas companies is set to start circulating the Earth 15 times a day next month. Google plans to have the data mapped by the end of the year for the whole world to see. (Thanks Sergey.)
Methane is a potent greenhouse gas estimated to be responsible for nearly a third of human-caused global warming. Scientists say slashing methane emissions is one of the fastest ways to slow the climate crisis because methane has 80 times the warming power of carbon dioxide over a decade. Though farming is the largest source of methane emissions from human activities, the energy sector is a close second. Oil, gas, and coal operations are thought to account for 40% of global methane emissions from human activities. The IEA says focusing on the energy sector should be a priority, in part because reducing methane leaks is cost-effective. Leaking gas can be captured and sold, and the technology to do that is relatively cheap.
Two new methane-detecting satellites - Carbon Mapper and MethaneSAT/EDF are now surveying the planet's climate. Because the Biden admin pushed through the quality methane satellites, the information will be so widely seen that members of the public will be able to act on their own - even despite a suborned EPA and Justice dept. A case where the right may be bitten by the 'market/consumer alternative to government' that they have long raved about.
== Dark comets, Dwarf galaxies - and Dark Matter ==
If I had followed my original scientific path – not lured away by the likes of you telling me to write more scifi – I’d likely have been in the mix of these studies of “dark comets,” whose orbits get significantly altered by gassy or dusty emissions, the way it happens with regular, icy comets, but without any visible signs of watery volatiles. “dark comets are different from another intermediary category between asteroids and comets, known as active asteroids, although there may be some overlap. Active asteroids are objects without ice that produce a cloud of dust around them, for a variety of reasons…”
Only the Dark Comets – and some include the odd cigar-shaped interstellar visitor ‘Oumuamua' – still have no firm explanation. Though some theories suggest emission of some volatile substance that doesn’t leave an ionized spectral trace.
The Milky Way’s central (huge) black hole is spinning surprisingly fast and out of orientation with the rest of the galaxy; the reasons remain unknown. Now, data from the Event Horizon Telescope - that first captured the black hole's image in 2022 has revealed a clue: The Sagittarius A* we see today was born from a cataclysmic merger with another giant black hole billions of years ago.
Dark matter might not just be the silent partner of the universe—it could be the secret to understanding how supermassive black holes unite in their deadly dance.
Attempts to figure out dark matter have pinned hopes on the possibility that the dark… bits… whatever they might be… interact with regular matter in some way – even very slightly – beyond just gravity. At least that’s been the hope of particle physicists with their big machines. So far, the indicators suggest ‘only gravity.’ But this study of nearby anomalous dwarf galaxies hints there might be just a little something more.
== A couple of final notes about you-know-what ==
Science is - above all - about chasing down what's true about objective reality, even when the results conflict with your wishes or preconceptions.
This human-invented process has led to all of the benefits of enlightenment: unprecedented wealth, comfort, knowledge, safety and - yes - comparative peace... along withg our recent ambitions to overcome a myriad errors through cheerful exchange of criticism. Errors like prejudicial assumptions about whole classes of people. Errors like mismanaging a fragile planet.
Alas, science is a rare phenomenon. Rare across human history and -- given the way that evolution works -- probably rare across the universe. (My own top explanation for the Fermi Paradox, by the way.)
Across human history, science - and its ancillary arts like equality before law - almost never happened. Instead, people in most societies preferred stories. Incantations about the world, told by their parents and then by priests and by kings. I know about this, having had successful careers in both science and storytelling. I know the differences and the overlaps very well.
While romance and stories are essential to being human, they also can lead directly to horrors and Auschwitz, if they allow evil incantation-spewers to rile up whole populations toward hatred and cauterized hope.
Anyone who does not recognize what I just described as THE essential thing now happening across the globe is already lost to reason.
Moreover, if the recent trend - reverting human civilization back to 10,000 years of nescient rule by inheritance brats and chanting incantation spinners - does succeed at suppressing the rare era of science, then we'll truly have our answer for why no voices can be heard ac ross the cosmos.
