Well, answer posts are supposed to actually answer the question. As you say yourself, it couldn't be clearer what the question is: it's "Have light gases like hydrogen or helium been explored for ion propulsion?" I think that your first answer post is inappropriate because it does not answer that question, and I think that's why that post was ...

The question couldn't be clearer The title reads Have light gases like hydrogen or helium been explored for ion propulsion? and in the body the question is repeated: Has the "ion sorcery" for light gases like hydrogen and helium been explored experimentally for future ion propulsion technology? What about neon at least? These are the only ...

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 ...

I think that this question should be closed: Is streamline body shape essential for propagation in the vacuum of space? As it seems to be a duplicate of this: Are there enough stray gasses in space to justify streamlining a probe?

I have gone ahead and appropriately re-tagged all 18 questions. The tag is now empty. Could a mod please delete it and set this meta-post status-completed? Future questions should use radio-communication, radio-astronomy, or radio-telescope as appropriate.

Questioners are expected to do a minimal amount of homework before asking their questions. One aspect of that homework is to find the purpose of the element of the StackExchange network where the question is being asked, and whether the question they want to ask fits in that framework. Another aspect of what is appropriate to ask is that questions should ...

If you think a question is poor or inappropriate or irrelevant enough to take a downvote, can you do your part and explain what you think makes the question weak? This is a very good point! If and when possible we should "-1 because..." even if it's short. Ideally it should be something actionable so that the question author, especially if they ...

On one hand, there seems to be a fair number of new users recently asking questions. Many of them are poor quality for the usual reasons (off-topic, unclear, duplicate, etc.). On the other hand, that's all the more of a reason to be nice and try to be helpful to these users! Help them to write better questions, instead of driving them away. Who knows, ...

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 ...

Here are my question candidates. How was the SK-1 spacesuit tested prior to Gagarin's flight? (the Ivan Ivanovich mannequin is at least one potential answer) What measures did Vostok cosmonauts have to control cabin fires? (question particularly considers the death of Valentin Bondarenko) What led Yuri Gagarin to believe his hatch was not properly sealed? ...

I've gone ahead and adjusted tagging on: Was it a "Soviet military satellite not in any of the catalogs?" Is the recently discovered VLF-induced radiation barrier in any way important or useful? Everything else stated at the moment seems okay to me.

I can agree it with the condition that it does not destroy content. All the removed radio tags should be replaced by a more specific one (radio-astronomy, radio-communication, and so on). So it is not deletion, but improvement (more specific tag -> more information). Or any edit is okay, if the total information content (measured in bits) grows and does ...

a bot that will track new tags created each week and make a post here on meta with the new tags (assuming there is 1 or more) In principle it sounds wonderful! For example, at the bottom of moderation tools for last 30 days I see we have many tags that should not have been created and need to go to the corn field ASAP. Many people will experience a sense 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:

The "voting system" is no panacea. Close voting is not just an expression of an opinion like a comment is. It takes only five (or less) users to shut down a question and prevent anyone from posting an answer. It then takes days to reopen with five more votes, slowing down and discouraging prospective answerers from putting in the time and effort to ...

There are many fields of science and engineering that overlap space exploration. Certainly chemistry is one, as is physics, biology, geology, etc. Chemistry is important to space exploration in more ways than just combustion chamber relations - there are the reactions that take place in fuel cells, in the shocks of reentry vehicles, in life support equipment,...
