From a posting about 6/21 at Mojave's Scaled Composites Space Ship One
launch event:

There will be a press conference 2 hours after the flight, at which
time the FAA will award the first ever Commercial Pilot's License
with Astronaut rating.

Forget the instrument rating I was thinking of, I want an astronaut
rating! I wonder what FBO will rent me a space ship and who I can get
to instruct me? Actually, since it's above FL180, I'll need the
instrument rating too, and a high altitude endorsement, and a jet
endorsement (or is that last a type?) And, since there's no mention
of a Private Pilot's Astronaut rating, I'll need the Commercial
Pilot's license too.

Sounds like a busy training plan for me...
