I would rather see the money spent on sending people to the moon or mars.At least that could actually lead to something productive,like an off
world base.
Aiming for an asteroid is all well and good,and may help iron out hardware issues I suppose,but I think by now we should be aiming higher.
I'd have to disagree here.
It would take us many decades to establish an off world base and develop the technologies to make it successful and sustainable, and in the mean time
we are potentially vulnerable to large NEO impacts.
Also, we might successfully establish a colony, only to find out there is an impact imminent, and without having developed the technology we need to
mitigate the impact threat. We'd be up # creek without a paddle...
I'd argue that we need to find out how to deflect asteroids as soon as we can, and it should be made a priority. The first step would be a mission
like the one proposed here, and it could give us invaluable information regarding the problem we are up against.
There is no reason why we could not invest some resources into establishing off-world colonies at the same time, but I think it would be a mistake to
take our eyes off what is potentially our greatest threat, wherever we are. Let's not forget that big hit is long overdue, although it may not happen
tomorrow or even in the next decade, but why take the risk?
A mission to an asteroid could actually be a good stepping-stone to establishing an off world colony too, and would be sure to teach us much along
those lines, so I think it's more than worth the effort and cost.
