From sometime around 1963, a few photos of wind tunnel models at NASA-Langley. Shown are a range of Dyna Soar models, from pre-Dyna Soar “HYWARDS” concepts to the initial Boeing 844 design to the final Boeing Model 2050E configuration.

A chart from a NASA briefing from May of this year giving a quick look at three planned configurations of the Space Launch System which some/many in NASA hope to get built and flown in the coming years.

When transitioning from the Block 1 to Block 1A configurations, the plan is to replace the Shuttle-derived five segment solid rocket boosters with all-new advanced boosters, either liquid or solid. But history has shown that if what you’ve got *now* more or less works, replacing it with an expensive new rocket is a somewhat politically dubious prospect.
