I'm studying space exploration MSc at the TUDelft (netherlands), so this site naturally attracts me. However I see alot of questions on this site I would deem as "way too broad to answer".
Sure many of those questions I could answer and give some insight, but I'll end up writing books before I even get to the real question. As both because the question itself is broad (Even for a PHd), and more importantly: I wonder how many steps I could skip.
I could go into detail about any such development over the last 50 years. And to correctly describe the changes and the effects of those researches would require me to explain post graduate research...
Or take: What is the largest hurdle of the mission to Mars? This is actually impossible to answer before doing it, and one could keep guessing for infinite time focussing on anything.
Or Does a mission to Venus orbit require less propellant than a similar mission to Mars?
The question itself might be easy to answer, but an actual good answer requires understand of delta-v budgets, gravity losses and specific impulse. All terms not even mentioned by the poster.
So what is the correct action I should take?
