three months after my suggestion on ghostNASA (only a coincidence, of course) NASA appears close to adopt only expendable SRBs for (both) Ares_I and Ares _V
as explained in my ghostNASA's post, this is a very good news for NASA budget since the saving of a refurbished SRB is only (about) 10% of the price of a new motor, while, retrieve the SRBs from ocean has a fixed cost of $500M per year
another good news is that an expendable SRB (without parachutes and retrieval systems) may increase the Ares_I payload of an extra 10-12 mT, and, since the definitive (fueled) Orion+SM mass will be around 10-15% less than planned (then, under 18 mT) that NASA choice may be due to one of these reasons (or both):
a) the new 5-seg.SRB Ares_I has not sufficient power to lift the Orion, as evaluated in my SRB article (and as rumored latest weeks) or...
b) they want more payload to launch an ISS/lunar "CorkScrew" Orion AND a powerful "SwissKnife Orion"...
