Send up an Apollo series type rocket and have a Neil Armstrong type get a sample.
If we could land a man on the moon in the 1960s, surely we can do in again 50 years later.
We could except for two little problems:
.....No boosters (the remaining Saturn V parts are in museums)
.....No budget
Otherwise we'd be there already......GWB restarted the project, and expanded the budget......Obama has cancelled the budget.......it is not as important in his mind as his "social" agenda.....
On edit: It could theoretically be done utilizing one of the more recent series of Russian "heavy lift" boosters, but all of the modifications and redesign of the post-orbital vehicles would be so extensive (and expensive), that it would be cheaper to start from scratch.....
