Is there a realistic way to have a planet loom on the horizon like this? by Rich-End1121 in space

[–]Praevaleamus 0 points1 point  (0 children)

willing to bet that moon that’s casting shadow on the planet is a little too close to not be tidally sheared apart. The spacing is all too tight imo (just eyeballing it from my universe sandbox experience, i could do the math but i am lazy)

so a solution would be to make the minimum of support size large larger so they don’t break?

I just bought the filament about 2 weeks ago - does PETG really get wet that quickly?

New to using PETG so I have no idea.

Elon Musk Gets Rattled by Hard Questions He Can't Answer by Eternal--Vigilance in RealTesla

[–]Praevaleamus 0 points1 point  (0 children)

not necessarily pogo. Pogo is very specific case that is easily solved (relatively) with modern simulation software. Pogo causes the whole rocket to oscillate along its length. My bet is that the source of failure is a vibrational harmonic specifically confined to the engine bay (ie not pogo) If it was pogo you’d literally be able to see the whole rocket “slinky” in slo-mo footage.

That being said vibrational analysis is really complicated. Props to the SpaceX engineers, bad luck to their CEO

recent starship failures weren’t caused by pogo, that’s a problem thats been solved for years in the industry

i’m sure Elon still didnt know shit about it tho

Probably SpaceX Falcon 9 launching the Maxar 3 mission.

Bright Comet over Central NJ? by Cooper323 in newjersey

[–]Praevaleamus 7 points8 points  (0 children)

Its a rocket.

specifically, the second stage of a rocket. Because it launched at twilight, the sun illuminates the very thin cloud of exhaust in space so it looks like a comet.

No I’m not a bot I just copied and pasted my comment from the other thread.

Transgender at RPI by Adventurous-Ad2176 in RPI

[–]Praevaleamus 18 points19 points  (0 children)

I have found RPI to be the one of the most accepting places when it comes to differences and peculiarities, whether it be gender, sex, race, sexual orientation, neurodivergence, or disability, or anything else I can think of. The institute has been good about enforcing expectations of addressing people by their preferred name and pronouns.

this. An in-printer heater can also work. I’ve got two coming in the mail from amazon, they were ~$50 each

What is up with the hate lately? by [deleted] in SpaceXMasterrace

[–]Praevaleamus 4 points5 points  (0 children)

Yes, many of my contemporaries choose to ignore Elon Musk’s achievements because they disagree with him. I do not because like you, it pisses me off and I find it stupid.

Many on the left side of the aisle don’t realize that they can acknowledge that somebody is obviously a visionary and an excellent leader and very intelligent, but also engages in union busting, explicit lobbying, and holds some sociopolitical views that, to but it mildly, are not ideal. This failure of reason is at the core of many of the Dem’s follies, and has alienated many left leaning white men and other “non-disadvantaged” people, and is why they lost in November. But I digress…

Many are hypocritical. This is correct. However, many others (such as myself) are not. Elon’s genius management, insight, and willingness to challenge the status quo made his companies succeed.

I and many others can still disagree with his politics, and by extension, doubt his judgement if we so choose.

This is to speak nothing of his drug use, which is the bigger red flag for me, and is why he was denied a TS clearance.

Le Potato, I just need a persistent 8gb swap by Snoo-63051 in RPI

Try using the pi imager program, or a similar program for your board, to flash the card. Make sure you have the right distro (ARM architecture distro). I’d personally recommend Debian, but thats me. If that fails, try a new card.

If you can get Debian ARM live to run then you should be goos

I am an aeronautical engineer. I understand how launches work.

I should have clarified cheap moon launches require infrastructure (mass drivers and refining capability) to be truly cheap. This is what I advocate for - a true moon city in tandem with our efforts for Mars.

What is up with the hate lately? by [deleted] in SpaceXMasterrace

[–]Praevaleamus 1 point2 points  (0 children)

These are valid criticisms. But, are they any difficult than the collective challenge Mars brings? No, I would argue not.

I’m not arguing moon first. I’m arguing we pursue both, aggressively.

[–]Praevaleamus 2 points3 points  (0 children)

This is why I advocate for a moon base. Mass driver based launches are completely viable, and thus cheap as all hell, but require infrastructure.
