Why reinvent the wheel?

To save both time and money. IIRC, the Ares I is just a shuttle SRM
stacked on top of an Atlas, both of which are off the shelf
components. To reconstruct the Saturn V would actually require
effort, but they had the Ares I designed about two months after Bush
announced the new plan.

So it looks like solid rockets are now fully trusted at NASA. During
the Moon missions, NASA management (i.e. Wernher von Braun) distrusted
solid rockets for good reason, and so solid rockets were off-limits.
That's why Saturn V was so big, it was liquid rocket that needed to
leave Earth orbit. You need a lot of liquid to do that.

As it turned out solid rockets were the reason for the first of the
two Space Shuttle disasters, Challenger. So NASA's initial objections
to solid rockets was verified. I suppose those redesigned O-rings have
now made these solid rockets "rock solid" for NASA.

AFAIK, this is the first time NASA has ever used an SRM for an upper
stage booster.
