NASA has posted the first ever HD video footage of the NASA recovery ships, Liberty Star and Freedom Star, retrieving the solid rocket boosters from a Space Shuttle launch.  These SRB’s helped lift Space Shuttle Discovery’s to orbit on STS-133.

This video includes underwater footage of the SRB’s as they are brought under control to be towed back to Cape Canaveral.  I never knew they dived to get them hooked up.

In the past they were refurbished for future use but unfortunately the program is ending and I assume these will not be re-worked.
