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.)

Factories…In…Space…

“Once you’ve exploited the solar system, there’s nowhere left to go.”

Frankly, the idea that we puny humans could ever even begin to damage the solar system is laughable.

What would be more worrisome is who – or what – would be doing the work. Why hire people if you could make robots to do the work for you?

One small step for (a) man…

Fifty years ago, human beings first stepped on the Moon.

It’s past time we went back. And stayed for good.

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.

Vulcan does not exist — but 40 Eridani does

As a kid I remember reading about “Vulcan,” which people used to think existed between Mercury and the Sun but always orbited on the opposite side.

Completely fictional, of course.

But…

Vulcan made a comeback as the fictional home of Spock in Star Trek. It was said by Star Trek creator Gene Roddenberry to be orbiting around 40 Eridani (also called HD 26965), a triple star system in the constellation of Eridanus “the river” in the southern hemisphere just 16 light years distant. In September 2018, astronomers at the University of Florida in Gainesville found a “super-Earth” exoplanet orbiting exactly where Vulcan was said to be.

There is only one logical conclusion…

The Moon is a Shining Ball of…uh…Nickel?

“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground…”

Uh. OK. That’s a LOT of metal. Nickel and iron? Ancient asteroid impact? 300 kilometers deep?

Sounds like a “golden” mining opportunity…

…even enough to totally justify “the Moon is a part of Mars“?

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.

No “Planet McPlanetface” option. Sorry.

The three choices fit IAU naming regulations and are associated with mythological creatures and figures that reflect aspects of 2007 OR10’s physical properties, which include rock, water ice, possibly methane ice, and a surface that’s red in color.

Your three choices?

Gonggong (共工, the bringer of floods 洪 and chaos)

Holle (which I always thought was Hulda or Holda)

Vili (which I knew as Wela in English class)

At least these scientists learned an important lesson from our recent past…

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.
