EDIT: I would appreciate a moderator reply to this question given this comment by TildalWave♦ on a now deleted post. It seems strange to say "help support the policy" without clarity on what the policy is.
Motivation
As a newbie here I have been surprised at the number of questions that from my viewpoint lack basic research. Some examples are listed later in this post.
My own research
I investigated the Space Exploration help, which says (as all the other sites I participate in do):
Search, and research
Have you thoroughly searched for an answer before asking your question? Sharing your research helps everyone. Tell us what you found and why it didn’t meet your needs.
In his answer to When (if ever) should a question include general reference links? James Jenkins says
References in questions, imply that some basic research has been conducted. As a rule some research before asking a question, leads to better questions.
My thoughts exactly.
Discussion
Every site has it's own charter and character.
How the "rules" are interpreted is up to the Space.SE community, especially it's members with 3K rep (and access to close queues) and moderators.
Members with 350 rep can moderate first posts and late answers. In the event that I begin such moderation duties I would like a better understanding of the prevailing views here.
Examples
The merits of individual cases may/can/should be debated; taken together they show what I mean.
Why explore Ceres?
The first hit of this Google search gives Dawn Mission objectives page, and the first of this Google search gives the Dawn Mission page.Techniques for digital superluminal communication
This question is older, which may be a factor. Googling "superluminal communication" gives the Wikipedia page. It did exist at the time, and a bunch of the other links discuss the problem.Could the current dragon v2 heat shield withstand a reentry from the moon? Again, a simple Google search answers the question in the first hit.
What survives the actual launch of a rocket
Is a bare question with no hint of research, or observation. Any viewing of launch images or vids shows the launch facility to be intact in most cases.Could a spacecraft be made out of lunar materials?
This question turns out to be more interesting than it appears. It's an example of a question with no evidence of research, but the answers are more complex, with a "yes" and two "maybe"s.How is Martian water lost to space?
Googling how is water lost to space gives the Wikipedia Atmospheric escape article.Does ISS follow Earth's rotation?
The first hit from Googling "iss orbit" gives http://iss.astroviewer.net/.
Concluding remarks
Good, well researched and well-asked questions can require some solid work, but they and their answers give the site it's value.
I seek the community views on the demonstrated research required in Space.SE questions. Is it different to other SE sites? Is it evolving?
