Beening born in the year of Apollo 8 and growing up during the moon landings, Skylab and the introduction of the reusable Shuttle, I had great dreams of future space manned missions, which have come to nothing. It is really disappointing that after 54 years we only now staging a mission equivalent mission to Apollo 8, but not even manned.
The tens of billions spent on the SLS does not even given us a core rocket as powerful as the Saturn V, as most of the SLS's thrust is achieved by the use of Space Shuttle era solid boosters with extra segments. When the Shuttle came along we thought that was the end to giant throw away rockets, with just tiny capsules splashing down in the sea at the end of a mission.
Luckily Space X is working on something different and better.
