I could not disagree more

A hit piece on Elon Musk and his plans for Mars:

Mars Is a Hellhole

The money quote:

Sagan did believe in sending humans to Mars to first explore and eventually live there, to ensure humanity’s very long-term survival, but he also said this: “What shall we do with Mars? There are so many examples of human misuse of the Earth that even phrasing the question chills me. If there is life on Mars, I believe we should do nothing with Mars. Mars then belongs to the Martians, even if [they] are only microbes.”

Musk, by contrast, is encouraging a feeling of entitlement to the cosmos—that we can and must colonize space, regardless of who or what might be there, all for a long-shot chance at security.

Huh. There’s a fair amount to disagree with here.

Firstly, Sagan, much as I like a lot of what he did, was wrong about the microbes. If there are Martian microbes… great, wonderful, huzzah. If they do not pose a threat to terrestrial life – and they probably wouldn’t – then the proper place for them in the future is in the Marsopolis Public Zoo And Museum. Life on Mars had its shot. The planet is dying, if not already dead; if Mars is to become a living world, it will be because humans do it. Microbes do not have rights; they certainly do not have the right to Mars that even *rabbits* do.

Now, if the author wants to get into a debate about what right to life alien microbes have, I can put her in touch with some folks who have some things to say about the right to life of human embryos.That, I suspect, would make for some entertaining debating.

Secondly, her dismissal of Musks notions about colonizing Mars: the man is right. We, especially the Western World, more especially America, *should* feel entitled to the cosmos. Whenever I hear some woke MFer tell me to “stay in my lane,” my immediate response is “Lady, I’m an American: the entire accessible universe is my lane. See you on Titan, chump!”

Everywhere we look in the heavens we see resources free for the taking. And everywhere we look – at least so far – we see no sign of those resources being owned. It’s a universe of riches and possibilities, and it is, so far as we can tell, friggen’ empty. It’s not just our right to colonize, commercialize, industrialize and exploit, it’s our responsibility. Everywhere we go for the most mundane or venal reasons, we will take along the ecosystem of Earth, or at least some fraction thereof. We will spread life throughout the cosmos.

Woke nags like this sure as hell won’t, though.

Legitimate reasons exist to feel concerned for long-term human survival, and, yes, having the ability to travel more efficiently throughout the solar system would be good. But I question anyone among the richest people in the world who sells a story of caring so much for human survival that he must send rockets into space. Someone in his position could do so many things on our little blue dot itself to help those in need.

To laugh at Sagan’s words is to miss the point entirely: There really is only one true home for us—and we’re already here.

Uhhhhhhhhhhhhgh. Do I have to trot out Tsiolkovsky?

There was only one true home for us… the Olduvai Gorge. Until it wasn’t.

And note how she seems to think that *she* should be able to tell Musk how to spend his money. How many billionaires are there on Earth who *aren’t* spending their funds on building rockets? How many middle east oil billionaires are blowing far more than Musk is on SpaceX on truly useless self-aggrandizing crap? Why isn’t the author over yonder protesting the building – often with virtual slave labor – of vast and rather silly skyscrapers in the desert, or giant artificial island complexes? Why aren’t these billionaires instead following Israeli leads and making their deserts bloom?

Nah. Easier to whine about rockets because reasons.

I truly hope that Martian colonial craft will have names like “the Cecil Rhodes” and “the Rudyard Kipling.”

SN10: Flown, Landed, Exploded

It launched, flew up, hovered, came down and landed. Woo! But then it bounced slightly when it landed, but still stayed upright. But then, some five or so minutes later, the damn thing popped up in the air and exploded; the lower propellant tank seemed to have cut open.

Neutron

Soon to compete with SpaceX, the Rocket Lab “Neutron.” Building on their relatively dinky Electron, the Neutron will be able to orbit 8 metric tons (including manned payloads) and will feature a reusable first stage much akin to the Falcon 9 first stage.

It looks to be substantially stubbier than Falcon 9 which should make it much more stable on the landing pad which will likely be a ship or platform out at sea.

Rocket Lab is technically an American company, but the founder is a New Zealander and many launches occur from there as well. Much of the Electron manufacturing occurs in New Zealand; the 3D-printed rocket engines are made in California.

Rocket Lab, like SpaceX before it, should cause many, MANY heads to hang in shame. Who? Well, let’s start with the likes of Boeing and Lockheed. Those titans of the aerospace world should have had this sort of capability *decades* ago. But they chose not to. And the best they’ve come up with is the as-yet unflown “Vulcan,” which is *lame* comparatively. Who else? Oh… how about the United Kingdom? They used to have a planet-spanning empire. They used to have a pretty snazzy launch vehicle of their own, the Black Arrow… which they abandoned fifty years ago. And now New Zealand has not only surpassed *all* of the British Empire with their Electron (dinky as it it, its payload still exceeds that of the Black Arrow), if the Neutron comes along – which there’s no reason to suppose it won’t, though the initial launch date of 2024 might prove optimistic – then the UK will look *even* *worse.*

If Neutron works, then there’ll be no excuses whatsoever. Every nation on the planet *should* have their own launch capability… and in a number of cases, such as the US, their should be *dozens* of new launch vehicles competing to prove who can launch the most for the least.

Fleet Ballistic Missiles

From Polaris through Poseidon to Trident D-5:

Every one of those was proposed for alternate roles, from truck-towed and truck-launched land based strike missiles to air-launched and ground-launched satellite boosting systems. And they very likely *could* have done that. But they are just not really well suited for any role but sea launched ballistic missile due to the somewhat tricky propellants they use… high energy propellants so they can function adequately while still being able to fit in a small submarine. But for above-ground systems, they’d be somewhat dubious. The environment within a submarine is pretty consistent. For a missile stored in a warehouse and then hauled aloft by an airplane? The thermal and vibration environments will be highly variable.

Zenith Star Booster

This photo has popped up online before, but usually in pretty crummy resolution. It’s taken from “Aerojet – The Creative Company” and shows a mockup for a Titan-derived first stage booster rocket. It has double the engines of the standard Titan core stage, either two or four engines depending on how you want to count the LR-87 engines (one set of turbopumps, two combustion chambers) married to a 15-foot diameter core. This is described as a booster designed to loft the Zenith Star space-based laser weapon test system (the ZS was described and illustrated in US Spacecraft Projects #1). Documentation on this specific booster has always been somewhat lacking, though there have been quite a number of Large Diameter Core Titans designed by Aerojet and Martin over the years.

The goofiest things you’ll read all day

First up: a writer for Gizmodo flips her lid over the terrifying prospect of the Defense Department generating ten whole watts of electrical power in space with a solar panel:

The Pentagon Sent a Pizza Box-Sized Solar Panel Into Space, But I’m Sure Everything Is Fine

This solar panel is officially called the Photovoltaic Radiofrequency Antenna Module (PRAM), and it’s designed to capture the powerful blue light in space that doesn’t pass through the atmosphere. Navy scientists launched it last May using a mysterious drone called the X-37B, and it’s currently circling the Earth every 90 minutes. So right now, as I’m typing, there is a little solar panel looping the planet because the Department of Defense wanted to put it there. Somehow, this is not an episode of the X-Files, it is real life. …

The scientists want to send dozens of these panels to orbit the Earth, and they say if they scale up the project, it could produce enough electricity to fuel a whole city. But as far as I can tell, no one has been clamoring for space power. Myself and the other 99.9% of humanity would be perfectly happy with solar, wind, and other clean energy generated right here on Earth.

If these Defense Department scientists successfully get more of these panels into orbit, there’s no telling what horrors the nation will use them for.

Nobody wants space-based solar power according to this genetic defective.

Huh.

Bonus round, from the color-value reversed version of “Stormfront,” The Root:

‘Be Less White’: Coca-Cola Faces Backlash for Giving Wypipo Wonderful Advice in Diversity Training Program

“Be less white.”

If it were up to me, this would be America’s motto. Instead of the Pledge of Allegiance, children in school should stand up before class, put their hands over their hearts and shout “BE LESS WHITE” at the flag for five minutes before beginning the day’s lessons. (I’m old AF and I have no idea if students even have to say the pledge before school anymore, but still.) “Be less white” should be printed on t-shirts, bumper stickers, white people’s birth certificates, white people’s tombstones and it should replace “In God We Trust” on the back of U.S. currency.

Uh-huh. Read the comments for an extra dose of “my god humans are stupid.”

Perseverance vids and images

A NASA press conference livestream with some interesting vids. At 11:58 to about 15:00  you can see multiple camera angles of the actual landing… on the skycrane looking down at the suspended rover, on the rover looking up at the skycrane, on the rover looking down at the surface. Various still images start at about 28:44. The Mars Reconnaissance Orbiter was able to image the rover, the skycrane, the heat shield and the parachute scattered on the surface at 37:25… but more interestingly, a still image of the actual landing in process at 38:07, where you can see the parachutes fluttering away and the rocket exhaust scattering dust on the surface. The first audio recording from Mars is at 41:21, with a cleaned-up audio at 42:26 giving the sounds of winds on Mars. It’s not spectacular audio, but it’s better than anything produced by astrologers, gender studies majors or critical race theorists. Engineering rigor for the win. AGAIN.

Nuclear powered cars, baby!

Space colony art: slightly different

One of the things about art is… what’s the “right” version? These days most concept art is probably produced digitally so the colors are mathematically defined, at least in the original. They are of course easily tweaked… but the original can in theory be infinitely reproduced without alteration. But with old-school art, reproduction methods varied in accuracy. Photos would make paintings look different based on lighting and film stock and a myriad of other variables. And then simple *time* causes colors to change and fade in prints. So… what’s “right?” Whatever looks best, I suppose.

So here is a slightly differently  version of a piece of art I posted about late last month. The colors are distinctly different: last months post was brighter and more vibrant; this one is more subdued. Click here for the full rez version.

 

As comparison, here’s the one from a month ago:

It will hit the Martian atmosphere at 3:55 PM eastern coastal elite/12:55 left coast time (2:55 central/1:55 mountain flyover country time). With any luck, about seven minutes later it will hit the Martian surface at a speed that doesn’t turn the rover and it’s helicopter payload into scrap.

Here’s a chatty NASA live stream:
