The space industry as a whole doesn't always make all of its sources publicly available. Furthermore, many of the things that we talk about on this site are hypothetical situations. Sometimes getting the data is almost impossible, or we are looking for a needle in a haystack. For instance, the first few questions I see from your search of me are the ...

Here's my answer but I will certainly support a new canonical Mars question if someone wants to write it. Do we need a canonical Mars Landings Are Real answer? tl;dr: when the behavior rises to the level of trolling rather than good faith question asking, the details no longer need to match, so we can use the same question as a duplicate. Perhaps we can ...

I think it would be on topic because they are employed (at least in this instance) for the purpose of a space launch.

I don't think you're "wasting people's time" with that particular question, although I suppose people who are only interested in real-world space exploration and who consider games and fiction to be "waste of time" might disagree. While I somewhat understand the sentiment that comment likely came from,* I personally don't agree with it ...

I agree, to take that wording literally would wipe out hundreds of interesting questions about space exploration history. (Unless, I guess, the questioner is writing a book about space exploration)

To the question Should old questions by a deleted user not be re-asked just so someone can choose the accepted answer? I think the answer is a resounding: I agree; they should not be re-asked just so someone can choose the accepted answer. I think it was an oft-asked question in the main meta in the past, but it was long-since agreed that we just leave ...

Also see answers to Should I create a new tag? Above all else, do no harm! Before adding a new tag, we should perhaps do a little house cleaning, because if a new tag is simply created out of thin air, then we need to add it to all existing questions to which it applies. Rather than retagging as many as 200 questions, we should narrow the field. We should ...

If it's not about making or storing fuel at home, it would be welcome here. We have had questions about alternative fuels before, for example: How would the Saturn V have differed if the first stage was using liquid methane and LOX?

The current tags follow the names of the relevant Wikipedia articles: tiangong-1 refers to the first station, the single-module Tiangong-1. tiangong-2 refers to the second station, Tiangong-2, similar in construction to Tiangong-1. Wikipedia does have an article for Tiangong-3, which was cancelled in the design phase. tiangong-space-station refers to the ...

You won't name names, so I will. I'm the culprit. In my opinion, you exposed your opinion in your item #5 on your answer to Why aren't there any robotic missions on Europa or Enceladus? NASA gave up on the idea of "absolutely completely 100% certain sterile" (emphasis yours) over 55 years ago. I have tried, multiple times, with comments, to get you ...

I'm not going to say either way just yet, but I'll explore things to consider. Most of the questions that have the tag at the moment should not have it. So if we keep the tag and assume it's for "travel" in the tourism sense or in the sense of Travel SE but don't think that the tourism tag is sufficient, then we'd have to remove it from say three ...

My concern in the OP was directed towards the specific issue of there being a question asked out of context and and then potentially answered out of context - which did indeed happen in the comments. e.g. in the OP there was no clue as to the test environment (town backyard vs. licensed club area in a desert) no context about the size of the rocket or ...

I think fictitious subject matter clearly crosses a line. Our guideline for questions in the past has been that the fictive elements should be supporting information for the main question and not be part of the base question itself. Yes, this line can be fuzzy in certain creative hypothetical scenarios, such as ones I have been guilty of getting a little ...

I think there is some concern as to the scope of this site, and it is a reasonable concern. Because the tone we set for the questions might make a difference in attracting experts. We are very lucky to have quite a couple of either active or former personell in the industry or government agencies which regularly produce incredible answers. Its those kinds of ...

Users with 2,000 or more reputation already have such a report; it's in the moderation tools (near the bottom of the page). Thanks to @uhoh, this is how it looks like right now:

Looking at that one specifically, it is very obvious you didn't like Bob's answer, despite it being accurate (he wrote Yes, along with info as to why it wasn't used), and wrote a bit of an attack on him in your post without providing anything useful in an answer. You basically said "Yes, but I don't like the way Bob wrote it" Oh, and then you also ...

My go-to plotting method is Plotly, which generates amazing, interactive* figures in 3D and 2D. The resulting figures are either hosted on Plotly's web page, or in the form of an HTML file on your computer which you can open in any browser**. When you upload a plot to chart studio, you can easily share a link to that figure. They also provide you with embed ...

Meh. This seems to be a nitpick about how the answer was worded. "There is a lack of evidence, but ..." or "Other spacecraft ..." or some other wording might be better received. No sources supporting an answer? Then don't upvote it. Is the answer outright wrong? Then downvote it. But I don't think that applied in this case. That ...

The practical problems bit was placed for Stack Overflow. It doesn't apply to every site. Very few questions on this site are facing real life problems, and that doesn't apply to this site.

Some might be on topic here. If it is more rooted in the short term then this might be a fine site, but otherwise I would try http://worldbuilding.stackexchange.com .

Be aware that Stack Exchange themselves have specified that comments are not mandatory when voting (up or down) - yes, we all agree they could be helpful, but without any other comment, the downvote means what the tooltip says "This question does not show any research effort, is unclear or not useful" - which is pretty self explanatory. And while ...

I don't think we can have a blanket policy because screenshots of text are useful at times. When screenshots or imagery is necessary, ask the questioner or answerer to add an image description that is better than enter image description here. Since a good picture is worth 1000 words, that replacement for enter image description here had better be wordy. For ...

Tags which are only used once and have no tag wiki are automatically deleted after six months. I have a script which regularly checks untagged questions across the network and this edit was made 6.5 months after the question was posted. The Wayback Machine only has snapshots of your question from 2019 and later, so we can't be 100% sure, but given the ...

I will argue that anyone capable of building an ICBM already has the capability to figure out basic orbital mechanics. Therefore, who will such a question ban actually protect? To compare it to the exiting off-topic ruling of dangerous amateur experiments, that one protects people who can find a way to injure themselves given a litre of hydrazine, which is ...

The Criteria for the gold tag badge is difficult to meet, lesser badges do nothing. The site needs enough questions with the tag so that a user can get 1000 score on answers to the tag; with answers without downvotes they'd be a 10K user minimum, if they provided answers on only one tag. That reduces the number of users eligible. Our highest reputation user ...

Or is this a somewhat "invisible" feature that few discover? Hard to prove that, but my suspicion is yes. It is not mentioned in the tour, and in normal perusal of the site you're not likely to stumble across it unless you go digging into users' badges and happen across one who has a tag badge. It could be discovered by reading over the Help ...

Cesium.js is a Javascript library designed for visualizing dynamic geospatial data in 3D. It was developped by the same team that developped AGI's STK software. The library is free to use and is very rich in content. Sandcastle is Cesium's IDE-in-a-webpage where people can test their code and visualize the results. One of the recommended ways to use the ...

This answer is not intended to compete with @Puffin's answer but rather to supplement it. Issues of whether we as a community think questions about rocket guidance are "safe" aside, this starts getting dangerously close to export control issues, both under ITAR and EAR. It's important to note that ITAR and EAR do not necessarily prohibit building ...

I only use the status-completed tag on a discussion if there is some mod action required, and really only on tag questions pretty much. All it means is that the mod action has been completed. It doesn't necessarily mean more discussion can't happen, though in cases where mod action has already been taken, it's probably better to start a new meta discussion ...

If the community determines the questions are true duplicates, then they can close the older one as a duplicate of yours. There is no rule that prevents this. We just usually close newer ones because the topic has already been dealt with appropriately, but if your question is more likely to attract good answers than the other it makes more sense to close the ...
