Life on Trappist 1e?

September 12, 2025

In two separate papers published Monday in the Astrophysical Journal Letters, astronomers zeroed in on the TRAPPIST-1 system, which consists of seven rocky planets that orbit a single star. Both studies outlined initial results from observations by NASA’s James Webb Space Telescope, suggesting that one planet in particular, known as TRAPPIST-1e, may have a nitrogen-rich atmosphere like Earth’s, though follow-up studies are needed to confirm the discovery.

Trappist 1e is in the “Goldilocks zone” in orbit around its star (i.e., not too cold, not too hot, just right). However, the Webb telescope can’t determine whether its atmosphere has any carbon dioxide, hydrogen, or oxygen, only nitrogen. Yet nitrogen is a clear sign that life is possible, because without nitrogen, DNA and other proteins are not possible. Of course, it could be simply a whole lot of microbes. Or even just ammonia.

Closer to home, the Mars rover Perseverance has found evidence of life in the distant past. Maybe. It found evidence that certain rock features may have happened because of microbes.

May.

That’s how science works, folks. A whole lot of maybes.

(I still think we need more catchy names for the Trappists. I mean, come on.

How Star Trek helped NASA make better shuttle names

Gorog summarised in the memo:

This group comprises millions of individuals who are deeply interested in our space programme

The name “Enterprise” is tied in with the system on which the Nation’s economic structure is built.

Use of the name would provide a substantial human interest appeal to the rollout ceremonies scheduled for this month in California, where the aeronautical industry is of vital importance.

It is really too bad that the shuttle looked nothing at all like the Enterprise (Constitution class).

And an odd coincidence that the original name chosen by NASA was…

…Constitution…

New study of moons of Uranus suggests life

Note: this is artwork and not an actual image

The planet Uranus and its five biggest moons may not be the dead sterile worlds that scientists have long thought.

Instead, they may have oceans, and the moons may even be capable of supporting life, scientists say.

https://www.bbc.com/news/articles/cgk1333k0ypo

Cue the jokes in five…four…three…

“So, you mean there really is life in…ah…”

Note that this is not from new data. It’s a re-analysis of what Voyager 2 sent back decades ago. Basically, it just had a bad day, with magnetic storms screwing up the scan.

Still…

There could be moons there that could have the conditions that are necessary for life, they might have oceans that below the surface that could be teeming with fish!

I think this is a bit of an exaggeration…

Gas…stations…in…space…! ⛽️

Jas Tiruvuru, business development manager for Orbit Fab in the UK and Europe, said the company was aiming to successfully demonstrate the technology in space by 2027.

“This will essentially be the first ever satellite to satellite refuelling demonstration funded here in the UK,” she said.

“Once we’ve proven that we can refuel to two spacecrafts we’ll be able to unlock a huge market potential.”

https://www.bbc.com/news/articles/c5y3wzlvnn2o

You know, maybe it’s just me, but I think 2027 may be a little optimistic. Just like the figure given in the article for how much the satellite sector will be worth in the future.

Aren’t there too many satellites already?

I’d like to see how this would help us colonize the solar system.

Actually, I’d like to see how they plan to get fuel up there in the first place.

Maybe my novel’s idea of using certain moons of Jupiter or Saturn as giant space gas pumps might help? 🪐

Interstellar! If only…

According to Thorne, who served as a consultant on the science of Interstellar, quantum mechanics could hypothetically explain a way to time travel via wormhole. So far, it’s a thought experiment that leads to the conclusion that you’d lose information along the way—not very practical.

First off, I’m incredibly annoyed at the way WordPress has screwed up the “quotation” function. It seems they are more focused on encouraging bloggers to use AI to write.

Uh. I don’t need AI. I blog. The end. WTH is the point of using AI to write my thoughts? It’s already being trained to USE my blog in the first place! Idiots.

OK. Second, the Popular Mechanics article I’m linking to is entitled “Interstellar travel is possible if we break into a higher dimension, scientists say.”

Only, that is NOT what scientists say. It’s still a thought experiment!

China just returned rocks from the Far Side of the Moon

June 26, 2024

But China has also offered to share at least some of its new moon samples with American researchers, and NASA is allowing the U.S. scientists to submit proposals.

https://www.npr.org/2024/06/24/nx-s1-5015208/china-return-first-ever-sample-return-moon-far-side

This is a welcome change of heart. International politics need not prevent international space exploration.

On the other hand…

China is not planning a mere short-term, flags-and-footprints presence on the Moon. Their ambition is more like Nasa’s Artemis than it is Apollo. China plans to launch two separate missions to the south pole of the Moon around 2026 and 2028 – including testing using lunar soil to 3D print bricks – as precursors to a lunar base.

A little competition might be just what’s needed to get humanity into space.

But a little competition might also go a bit too far…

“May you live in interesting times…”

Nuclear power on the Moon. Gee, no problem…

May 13, 2024

The South Pole, where power plants are likely to be constructed (without human help…)

“The truth is that nuclear is the only option to power a moonbase,” says Simon Middleburgh from the Nuclear Futures Institute at Bangor University in Wales.

https://www.bbc.com/future/article/20240417-the-nuclear-reactors-that-could-power-moon-bases

So far there are two major consortiums that have plans for moon bases:

The Artemis Accords, with 36 countries (the US, Japan, South Korea, UAE, India, etc.)

The countries that don’t like the US, the UK, and Canada (China, Russia, Belarus, Venezuela, Pakistan, South Africa, Egypt, Ajerbaijan)

OK, maybe a bit of an exaggeration, granted.

But there is no doubting the political ramifications of two competing groups of astronauts (cosmonauts, taikonauts) on the Moon.

And just wait until they get to Mars.

Imagine what might happen. (I did!)

“May you live in interesting times…”

Venus used to have as much water as Earth. What happened?

May 7, 2024
MThomas

Over time, that water has nearly all been lost. Figuring out how, when and why Venus lost its water helps planetary scientists like me understand what makes a planet habitable — or what can make a habitable planet transform into an uninhabitable world.
https://theconversation.com/venus-is-losing-water-faster-than-previously-thought-heres-what-that-could-mean-for-the-early-planets-habitability-229342

The process in which Venus lost most of its water is called “hydrodynamic escape.” When Venus got too hot, the hydrogen in its atmosphere left. (The linked article explains this using a metaphor of having too many blankets on your bed.)

However, Venus is still losing hydrogen, even though there is too little of it for hydrodynamic escape to work. So, logically, there must be another process at work: “HCO⁺ dissociative recombination,” in which individually positively charged atoms of hydrogen, carbon, and oxygen in the atmosphere react with negatively charged electrons. The process was first examined on Mars, and based on a reexamination of results from previous missions (Pioneer Venus 1 and Pioneer Venus 2), the same research group thinks it’s time to try it on Venus…perhaps a first step to seeing whether Venus had life at some point.

Can you say “Catch-22” in space?

Japanese space company Astroscale Holdings Inc has unveiled what it calls the world’s first publicly released close-up image taken of space debris, hailing it as progress toward understanding the challenges posed by trash orbiting Earth.

Hmm.🤔 what will happen to the rocket and the satellite that took this picture?

WASP-76b is a hellish planet – but with “glory”

April 11, 2024
MThomas

There are many words that could be used to describe WASP-76b — hellish, scorching, turbulent, chaotic, and even violent. This is a planet outside the solar system that sits so close to its star it gets hot enough to vaporize lead. So, as you can imagine, until now, “glorious” wasn’t one of those words.

This planet (located in the constellation Pisces) seems to have a rainbow effect of concentric rings…despite being so hot that iron falls from the sky.
