the SOLUTION for the Ares-1 and 5-segments SRB dangerous "vibrations" ALREADY EXISTS
I've suggested the solution of all Ares-1 problems TEN MONTHS AGO in my "Ares-F" article:
http://www.gaetanomarano.it/articles/024aresF.html
the SRB-5 vibrations problems (that's unexisting in the 4-segments SRB) comes from it's lenght and the fact that it's a SINGLE motor
well, my Ares-1 design uses three (shorter, smaller and cheaper) Ariane-5 EAPs, then, it could have LESS "vibrations" problems of the 4-segments SRBs!!!
also, this solution adds many advantages, since the three EAPs...
1. they have the SAME burning time of the SRBs
2. thay give MORE thrust of the (theoric) 5-segments SRB
3. they are READY AVAILABLE NOW while, the 5-segments SRB (IF works) will be available in 2011
4. the three EAP are cheap like an expendable 4-segments SRB ($45M) since each EAP costs only $15M while the 5-segments SRBs will be VERY HIGH PRICED:

a further suggestion in my article is to use the (J-2X similar) Vulcain 2 tha's READY AVAILABLE NOW and only need to be man-rated and air-started (while the J-2X will be ready to fly after 2012)
about the "political" problem of the Ares-F hardware... just buy the EAP and Vulcain 2 license and do make them in USA by ATK and Pratt & Whitney Rocketdyne
this is the only viable solution to save time and money and have the Ares-F ready to fly within 3-4 years (then, just in time to launch the Orion, that will be ready to fly in 2012)
and, don't forget, that my Ares-F will replace a rocket (the current design Ares-1) that ("vibrations or not vibrations") can't fly:

During his speech yesterday about the Constellation architecture, Mike Griffin talked in detail about the possible thrust oscillation problem and then discussed the different ways it could be solved.

my proposal has several other advantages rather than just solve the "vibrations" problem (if any)
