The exciting world of regolith oxygen extraction

October 25, 2019
MThomas

Future moon settlers might benefit from oxygen extraction from lunar regolith as it can be used to create breathable air as well as a source for fuel. In addition, the newly found extraction method might also be useful for Mars colonization.

Regolith covers the Moon and Mars (and presumably many other potentially habitable rocky bodies).

Of course, the composition of regolith on the Moon differs from that of Mars.

But if the new method can extract sufficient quantities of both oxygen and hydrogen, there should be ample amounts for both human usage and rocket fuel.

(Yawn.) “Dry” science? Sure. But think of the (fictional) possibilities!

Have Gravity Link Spaceship, Will Travel?

October 16, 2019

Youtuber smallstars has proposed a concept that he calls the Gravity Link Starship (GLS), a variation of SpaceX’s Starshipthat will be able to provide its own artificial gravity.

Hm, I guess we’re at the point where YouTubers have better ideas than NASA…

But who pays for this? is the several billion dollar question. Not just the construction of the “hub and truss” system, but the expense of getting it into space in the first place.

Seems like science fiction at this point. But still worth a read/look:

“We already found life on Mars!” Um. Sorry, no, you didn’t.

“What is the evidence against the possibility of life on Mars?” Levin wrote. “The astonishing fact is that there is none.”

Uh, no, sorry. That’s an illogical fallacy called “begging the question.”

Often phrased like this: “Absence of evidence is not evidence of absence.”

Or, as a friend once joked, “Just because you haven’t found any aliens doesn’t mean there aren’t any!”

Well, yeah, but that doesn’t prove anything except that we just don’t know.

See, science doesn’t work like that. It demands skepticism, careful theorizing based on positive evidence.

And replication.

If findings can’t be independently confirmed and reproduced by an outside observer, then the evidence isn’t strong enough.

Sorry. No smoking gun. Yet.

(Believe me, if scientists knew that Mars had life, we’d hear about it ad infinitum. Carl Sagan put it best: Scientists are terrible at keeping secrets.)

Space Hopper Go!

I have a vehicle in my novel called a “Hopper.”

Damn you, Musk! Must you steal ALL my ideas??

No, the “golden asteroid” will NOT make you rich

I wrote about this a couple of days ago (based on an article from two weeks prior), but it’s interesting to see random websites suddenly jumping on the “we’ll all get rich!” asteroid mining band wagon. Hey, everybody, let’s copy-paste stuff and not use our brains!

A new article by rt.com even includes two click-bait links to “how gold was formed” that have nothing whatsoever to do with NASA’s probe to (16) Psyche. Of course, we shouldn’t expect any less from an obvious Russian “news” distributor. But in the interests of calling out the bad reporting in this and similar “news” articles spread online recently, let’s give this a hearty smack-down.

Interstellar Travel Tech — oh, Really?

Interstellar

“It is time to venture beyond the known planets, on toward the stars.”

Yes, I agree, but I don’t see how any of the ideas in this article will help us achieve that goal. I think the problem is the reliance on conventional means of propulsion. Clearly some sort of bending of space/time is needed to leave the solar system faster than, say, a decade, let alone reach other star systems.

Dawn already used an ion engine (way too slow). The solar gravitational lens is neat but it won’t take us there physically. The “space-based laser” idea is funky but impractical.

Getting off Earth should help (Moon Base, Mars, somewhere else like Triton). Escaping our own planet’s gravity well takes way too much effort. But after that, it’s time to forget about rockets and start thinking of truly “wacked out” ideas.

For starters, Discover, how about dumping your absolutely awful page design? Yeesh, this page is hard to read.

Gateway now includes Canada, eh

Now that Trudeau has agreed to help out, if anything goes wrong we can always “Blame Canada!”

No, no, it’s a joke, alright, eh. Sorry, sorry.

On to Triton. With Trident. Finally.

We’ve learned a lot about Neptune’s largest moon, Triton, since it was first discovered in 1846. Some scientists believe it could be an “ocean world” with liquid water — and maybe even harbor life.

And now, pending approval, we might soon get our best glimpse yet. NASA’s Jet Propulsion Laboratory proposed on Tuesday [19 March 2019] at a conference in Texas to send a spacecraft called “Trident” to Triton — with the goal of sussing out whether it’s a habitable world.

A low-cost mission that would give us decent photos and even video of Triton, Io, and even Venus. Let’s do this.

Bennu’s Intergalactical Glitterspray Show!

OK, not actually glitterspray. Lots of tiny moons. Micromoons?

Exploding out of Bennu, which is an asteroid circling way out near Pluto right now, but will intersect Earth’s orbit in September 2060. And in 2135. And in 2175. And maybe soon again after that.

Doomsayers, prepare yourselves!

(Cumulative 1 in 2700 chance it’ll hit Earth by then. Too bad Bruce Willis won’t be around to save us.)

New Earth discovered only 70,000 years away

new-earth-2

Welp, it’s official. NASA announced they have confirmed another “Earth” (really, an “Earth-like planet” simply means it has enough water and is in the right orbit from its star to hypothetically support life).

Too bad it’s 500 light years away, which currently would take us a mere 70,000 years to reach.

But it’s a start…
