Dear Dr. Bolden:

Although I am not an enthusiastic fan of the Space Launch System, preferring instead  an advancement to fully reusables, I wanted you to be aware of the origin of the SLS concept that features liquid fueled boosters.

In my 1992 book, THE FUTURE OF US ROCKETRY, on page 143, I present a configuration for a heavy lifter that  is very much the same as that being planned for the evolved version of the SLS.

I thought this bit of information would save some embarrassment, should someone else be credited with creating the conceptual design. 

Sincerely,


Edward Hujsak
