New “habitable” Earth? 🌍

January 10, 2020
MThomas

The newly discovered exoplanet, called TOI 700 d, is located about 100 light-years away from us and is roughly 20% larger than Earth.

Okay, not exactly close, but looking good…

A year on TOI 700 d takes 37 days.

Um. Wait. What?

One thing astronomers have discovered though is that TOI 700 d is tidally locked to its star, which means that one half bathes in eternal sunlight, and the other half always exists in darkness.

Oy.

And even better…

One of the burning questions is whether the planet has an atmosphere or not.

Is this really the best way to phrase this? 😂

I vote we pass on this one…

PS I’ve been trying futilely to get WordPress not to screw up the formatting. To no avail.

Khufu, I mean, Cheops is a go!

Ever wonder this about “Super Earths”?

Do they have atmospheres and how thick are they? What kind of clouds? Do they possess oceans on their surface? Do they have rings and moons? Cheops ought to be able to address such questions just from looking for these tiny dips in light during a transit.

ESA finally does something! Wow. Go Europe!

I love how BBC says “The Americans” when referring to NASA, as if a) American is an ethnic group and b) all NASA scientists are American.

But anyway…

Prof Didier Queloz, who won this year’s Physics Nobel for discovering the first planet orbiting a Sun-like star in 1995, was on hand to watch the launch.

You can watch/listen to his interview here.

ESA and NASA? Airbus? Still not ready? 🤦‍♂️

Right now, engineers have got a dummy rover practising the business of retrieving packaged rock samples. And, yes, the stand-ins really are whiteboard markers.

Yay! Whiteboard markers. Um. OK.

But different agencies and companies are finally working together?

Great!

Wait. What’s the catch?

It is, though, going to take more than a decade to achieve.

Sigh.

It’s life, Jim, but not as we know it. Maybe.

The pattern remains a mystery, but researchers are beginning to narrow the possibilities.

While the changes are most likely…geological in nature, planetary scientists can’t completely rule out an explanation involving microbial life.

Just as the Viking landers claimed? Uh-oh.

Or is it just chemicals (perchlorate, bleach-like substances) in the soil, releasing oxygen and methane depending on the amount of sunlight/heat?

How would this affect humans who set up camps in the low-elevations areas, where they could be closer to water?

Hm…

The exciting world of regolith oxygen extraction

October 25, 2019

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.

October 15, 2019
MThomas

“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.
