Am I correct that the starship (upper stage) with all 6/7? engines installed doesn't have enough thrust to lift off from the ground fully fueled, and therefore cannot achieve orbit on its own.It would have to do this with the heavy first stage.

TWR >1 =/= SSTO.That being said, Starship is not designed to be SSTO from Earth, but is designed to be SSTO from Mars. It is designed to require Superheavy booster to achieve Earth orbit, required components all reusable.Contrast to SLS, which will not be SSTO from anywhere, has no component designed to lift off from Mars, and solid boosters to achieve Earth orbit, required components all expendable.The expendable camp is experiencing considerably embarrassing setbacks, considering it's heritage. Meanwhile, the reusable camp is experiencing exciting setbacks, considering it's rapidity.I voted for more exciting than embarrassing.
I voted SLS (despite disliking it and being a SpaceX amazing people).I think Starship will fly before SLS but not the full Superheavy/Starship stack.I expect difficulties revealed by Starship (not necessarily LOV) which will require several flights before the full stack can fly.
I last saw a TV commercial that featured a Shuttle Orbiter representation in mid 2019.(8 years after the program was retired after 4 decades of STS/SSP service.(1971-2011 plus T&R services). The Space Shuttle as a program represented American technological dominance. Will Orion "carry the torch"? I don't know how it will end up, but I'll no doubt enjoy the ride.
For this poll, success means either to orbit or deep space.
