who cares.. how about feeding all of the starving people and taking care of homeless first then if there is leftover crash things into space...
When I first started reading this I thought you were being sarcastic; spaceflight is a tiny fraction of a percent of the national budget here in the
US for another thing (and it's probably even a smaller percentage in Europe). Of all the things to spend money on, this is one of the most worthy.
I would rate it higher than government welfare.
we have been here for quite some time without smashing things into things in space
If the dinosaurs could have talked some 65 million years ago they probably would have said the same thing... right before an impact wiped them out.
That's a very short sighted perspective. It may be an unlikely event in any given year or even generation, but there is no higher consequence than
this and it is simply a matter of time. One day it will be on our doorstep and we will have either squandered our time that we could have spent
developing spaceflight capabilities, or we will be prepared and deflect the object.
Right now the list of potential impact threats is considerably long (neo.jpl.nasa.gov...
) and those are just the ones we know about. The
one's we don't know about are potentially even more dangerous. Right now there is a rock out there somewhere that will hit earth eventually, it's
simply a matter of when. If we don't find and identify it with enough warning (right now it would require years of warning) we will not be able to
do anything about it. If we don't test and improve our ability to deflect, then we will not be able to mount a defense if we don't get enough
warning. If we don't spend money on space, we're not going to get hardly any warning at all, and then all we can do is sit around and look like
fools as we "feed the homeless" right before they're all annihilated along with the rest of us.
I would thing that you would have a better chance messing things up then just leaving things alone and letting things work the way they do.
No. Setting objects on collision courses is hard work in orbital mechanics, even when we do it with deliberately controlled spacecraft it requires
careful planning and mid-course corrections. By selecting a safe velocity vector for impact you can eliminate the possibility of accidentally
inducing any future collision regardless of how much or how little delta-V you end up imparting. Finding out just how much delta-V you imparted is
important to improving and refining our ability to deflect future objects that actually do present an impact threat.
Why do we deserve to keep on living anyway if we cannot even help our fellow humans live even the simplest of lives and be happy, what is the
I'm all for charity and I do whatever I can to help those around me who have less than I do (and I don't have much), but I will not waver in my
support for spaceflight development so that we may one day deflect any rock headed our way just because not everyone is happy in life. We will NEVER
reach the point that everyone is well taken care of, but that is not an excuse to just sit idly by and allow any future impact to happen.
