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…

Long time, no…

Hi, everyone. I haven’t written a blog post in a very long time.

For various reasons.

I’ll see if I can start posting a few entries on recent science events in a few days (for starters, four astronauts finally arrived at the ISS, the first replacements following the Boeing Starliner fiasco).

But for right now, I want to follow up this short post with some analysis I got from our friend ChatGPT…

…about Adam’s Stepsons and Bringer of Light. Stay tuned!

Fifteen years and counting…

Hi, everyone. I know I haven’t posted in a while now (about three months).

Things happened. I’ll see if I can deal with that in a post this weekend before returning to regularly blogging about astronomy and etc.

Winter is still here! (In the northern hemisphere.) Going on walks and hiking in 3C windy weather only makes hot chocolate taste that much better…

New study of moons of Uranus suggests life

November 14, 2024

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? 🪐

Japan launches world’s first wooden satellite

Researchers at Kyoto University who developed it hope it may be possible in the future to replace some metals used in space exploration with wood.

https://www.bbc.com/news/articles/c5y3qzd5ql9o

The researchers argue that “if” trees could be planted on Mars…

OK, just stop right there. I’m pretty sure Mars will struggle to support even grass, let alone trees.

And the argument that, due to a lack of oxygen, flammable wooden structures in space would not be in danger strikes me as a bit ludicrous…surely there would be oxygen inside the wooden structures?

And, you know, I do think I’ve seen this before some where…nah…

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!

Chinese scientists “create” water from lunar soil

September 4, 2024

Using the new method, one metric tonne of lunar soil will be able to produce about 51 to 76 kilograms of water, equivalent to more than a hundred 500-millileter bottles of water, or the daily drinking water consumption of 50 people, the state broadcaster said.

https://www.nbcnews.com/science/space/chinese-scientists-use-lunar-soil-produce-water-rcna167951

The soil was from the 2020 expedition, which was the first in 44 years to bring back soil from the Moon.

Considering all of NASA’s problems, it looks like China will have a moon base years before the US does…and probably in prime resource locations as well.

And don’t forget that the hydrogen in the soil can also be used for rocket fuel. It would be a lot easier to launch ships to Mars and beyond without having to deal with Earth’s gravity…

China just returned rocks from the Far Side of the Moon

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…”
