Space Exploration Within Our Solar System

[Chris Sawatsky]

Being that once our star begins to run out of Hydrogen the entire solar system will die shortly after, should we not be focusing on finding other, younger systems with planets that can harbour and nurture life as well as faster space travel and most importantly, How to live on a planet without destroying its environment and having a negative effect on all other life forms on it? I realize that we are learning a lot by studying the other planets and moons within our solar system but now that science has proven that the slightest change to one planet or moon will have an effect on everything else, possibly causing changes to our orbit and/or rotation which has been sighted as being the cause of past ice ages and mass extinctions, should we be crashing satellites and probes into them once their fuel runs out? Are we risking our very future by haphazardly dealing with the left overs of our research in the way we always have? Should we be designing our space crafts in such a way that they can return to earth? Is the easiest way the best way ?

Do you have any discussion points pertaining to Astronomy and Cosmology?

This is wrong. Even in billions of years when we move out of the sun's main sequence and into the red giant phase, it won't "kill" "the entire solar system". It will change a great deal, but the system will still exist. Honestly, you need to study more and read popular science articles less.

What on Earth makes you think we aren't looking? Or, in your ignorance, do you imagine the efforts aren't "focused" enough for your understanding?

Trying to learn that now (we've only had one chance in the past), but some people insist on holding their ignorance close, like an old friend, and ignore our current efforts. I guess it's easier to gripe about it than learn about it.

You started out with a title about exploring our own solar system, then immediately went to "focusing on finding other, younger systems with planets that can harbour and nurture life", and ended with conspiracy, conflating crashing a satellite into the moon with mass extinction events. None of this has squat to do with Astronomy and Cosmology, it's a flawed starter right out of the gate with too many misconceptions, and past discussions with you (particularly wrt expansion vs explosion) have shown you're very wedded to your ideas and don't deal well with being corrected. 

Can you give me a focus for this thread (FTL travel in Engineering maybe, or Ecology & the Environment for a conversation about negative effects), so it doesn't end up like all the rest, with you getting your reputation marked down for being sloppy and unrigorous while nothing meaningful gets discussed?
