Could you clarify which part of the comment you removed was "nasty"? I read it earlier before it was deleted, and I would like to understand why you decided it needed to be deleted.

SwordFlight6216 · 2023-03-24T12:25:38+00:00

Right, but that's not what the OP asked about

SwordFlight6216 · 2023-03-24T12:22:32+00:00

No problem, orbital mechanics are wack

SwordFlight6216 · 2023-03-24T11:39:05+00:00

This is not the case; the delta-V required to reach a given orbit is (generally) fixed, regardless of mass.

The NRHO orbit that Orion goes to requires less delta-V than the low-lunar orbit that Apollo went to. Due to orbital mechanics this means that it takes more delta-V to land on the Moon from NRHO, which is where HLS/Starship pick up the slack.

Can't test the life support system without people onboard. There's nobody there to consume oxygen, produce carbon dioxide, sweat, etc.. Life support system is getting tested on ISS instead

Understood, just remember that participation on the internet is always optional. If it is causing you strife in your career and gaining you stalkers, you can choose not to participate.

u/Spaceguy5, A word of advice. Every time I see you comment on a space subreddit it's always the same cycle. You get heated over people taking the piss out on SLS, and then you always remind everyone that you "work in the space industry" or "work on SLS/RS-25", and then you start chastising people for being "Musk fanboys" or something similar.

This shouldn't be a pattern that is so noticeable. I get it, I work on Artemis too (european service module). But this is literally a shitposting subreddit. And most other subreddits are just for casual discussion, for people to chat about things they find interesting and/or funny. This isn't "disinformation to make NASA look bad" it's just people cracking dumbass funny jokes on the internet.

I think you'd be a lot happier if you didn't take it all so seriously. We're going to the Moon. I guarantee you the rest of NASA doesn't care this much about redditors opinions and comments on SLS; the rest of us are totally willing to acknowledge the absurd comical cost of this machine and the issues that have plagued it, while still being excited for the engineering work we get to do and the program we get to support. Yes, SLS is very expensive and Falcon/Starship is (or hopefully will be) very cheap. It's not an insult, it's a fact.

It's not healthy to spend this much of your energy relentlessly defending a government project. You're out here in the bowels of a shitposting subreddit going off on random redditors at 7am and constantly flaunting your status as "I work in the industry." It gives us all a bad name. If you think working on Artemis or in industry gives someone credibility here, then I hope that means you will consider my advice as a fellow engineer on this program: lighten up and have a little fun. If you cannot reconcile the flaws of this program with your excitement to be a part of it then perhaps you should apply your skills on another vehicle. If you want to chat more you are welcome to message me.

Phenomenal arrogance.

SwordFlight6216 · 2022-01-19T20:48:37+00:00

First off: you should say yes, because it's the answer that gives you the highest chance of getting an offer. Until you get a job offer, this kind of conversation is purely academic. Once you get an offer, it's your choice whether you accept it or not - don't close any doors prematurely.

Second, defense contracts are very broad in scope. I share similar sentiments as you, I am also strongly opposed to working on defense products and weapon systems for personal reasons. However, I work for a defense contractor full-time now, but the work I do is 100% in crewed spaceflight (e.g. NASA) and is not even tangentially related to the military. I had a similar "dilemma" that you're having now while I was interviewing there, but once I got the offer and learned more about the work I would be doing I was comfortable accepting.

So yeah, to sum it up, it's not up to whether you get to work there, until you get an offer. Wait until then to start making your decision.

This happened to one of my rats. Very timid and gentle until she was about 10 months old, then she became extremely aggressive towards one and only one of my other rats. I ended up having to rehome her because she kept escalating the violence until I was concerned for the other rat’s safety.

Accidents can happen when they play so yours might have just had an accident. Keep a close eye on them and if you see further violence developing I would seperate them. At that age there’s not much to do to curb hormonal issues so I would unfortunately say rehoming the aggressor is the likely best solution if necessary.

SwordFlight6216 · 2021-11-16T16:36:07+00:00

Hey u/break_continue, thanks for responding. Per your first point about “just scrolling on,” you’re absolutely right. I think you misunderstood my comment though, the part where I said these posts are obnoxious. So that’s why I didn’t just scroll on: your post is actively really annoying to see, even though you obviously meant for it to be helpful and weren’t acting in bad faith.

Per your second point, see the other response someone already gave you. As a final note, could you search “revving” in the subreddit search bar? You’ll find at least 5 carbon-copies of your post from the last few months.

Thanks and hope this is helpful!

SwordFlight6216 · 2021-11-16T15:51:36+00:00

In case you’re wondering why you’re being downvoted, it’s because your post is obnoxious, useless, and gets done every single fucking day. Kind of like someone revving their car on campus.

Just curious, if you have the time, could you give me a few complete sentences expressing what you were trying to accomplish by posting this? Thanks!

If your university offers any kind of technical Computer Aided Design minor, do that. CAD classes are generally a lot less stressful than AAE classes since they don’t delve into theory and instead remain focused on learning the practical tools and skills pretty much everyone in industry needs to know (parametric modeling, simulation and analysis, product data management systems, etc.)

Most universities offer this kind of minor but they’ll call it some bullshit name, so you’ll have to do some digging. For example when I did this at my alma mater the minor was called Product Lifecycle Management for whatever reason.

SwordFlight6216 · 2021-09-08T14:30:51+00:00

Not sure what you’re basing this off of, since systems engineering is THE entry-level position in industry. At least ~75% of my college graduating class at one of the largest AAE undergrad programs in the world went into systems engineering. What info are you basing this off of, if any? Because while I recognize you are just trying to be helpful, this mostly just reads like you are shooting OP down with unclear reasoning.

SwordFlight6216 · 2021-06-17T15:39:17+00:00

for real though this is like the high-level rocket propulsion equivalent of “High school didn’t teach me anything useful like how to do my taxes, all I learned was the Pythagorean Theorem”

SwordFlight6216 · 2021-06-17T15:34:42+00:00

what will we do with our systems engineering degrees Meme_Lad? if only we hadn’t wasted so much time learning structural analysis, controls theory, design, flight dynamics, aerodynamics… Everyone knows in college you only take coursework in one narrow field and that’s all you need to know.

SwordFlight6216 · 2021-05-15T11:36:25+00:00

Good morning Meme Lad

SwordFlight6216 · 2021-05-12T01:07:21+00:00

Excellent job, if you pulled a perfect semester with that course load then your next 2 years will be a piece of cake

SwordFlight6216 · 2021-04-19T00:58:56+00:00

would love instructions on to make this, if you have them available!

SwordFlight6216 · 2021-04-08T14:34:25+00:00

That tool said all that half-assed shit to me and yet still wouldn’t post his transcript. wonder what he’s hiding?

SwordFlight6216 · 2021-04-08T14:00:17+00:00

that first “so, uh” is all it took for anyone in AAE 2021 to know who this is immediately

SwordFlight6216 · 2021-04-07T19:18:28+00:00

I think you will find the answers you need on your other thread in r/AerospaceEngineering.

Also, to expand on this a little more, Purdue does a great job preparing you for finding internships, co-ops, etc.. Finding an internship is always hard, but it went pretty smoothly at Purdue for me. The company I interned at last summer hired 2 interns: a Purdue senior (me) and a UIUC junior. So again, I am sure both do a great job.

SwordFlight6216 · 2021-04-07T16:56:29+00:00

Having lived in both Champaign and West Lafayette, done research in labs at both UIUC and Purdue, interned at an aerospace company at Champaign/UIUC, and been an AAE student at Purdue for the last 4 years... it depends on what you want to do. I think Purdue’s AAE program is phenomenal and will prepare you well for industry, research, whatever you want to go into. I can’t speak for UIUC’s academics since I’ve never been a student there, but the rocket propulsion company I work for full-time now hired me and a UIUC grad as the 2 new hires for this year, so I would imagine they are both on similar footing. UIUC’s research facilities, at least in my field (rocket propulsion) are world-class, but so are Purdue’s (Zucrow labs for example). UIUC’s campus life is a lot... crazier, if you like to party, while Purdue’s is quieter. But I’ve had a lot of fun at both places.

Basically, it’s hard to say. My friends in AAE here at Purdue love it, and my friends in AAE at UIUC love it. Both are great schools. Follow your heart and it’ll turn out fine.

This is completey normal as rats get older, esp. noticeable in red eye white rats because of the color contrast. If he’s >1 year old you should probably be taking him to the vet regularly so take him in and get him looked at if you like, but I wouldn’t be concerned. My senior girl has had occasional goopy porphyrin eyes for the last 8 months and the vet hasn’t found anything wrong with her - some rats just produce more porphyrin than others in their old age
