The summary has gone like this from the 60's to now that is 50 years we are like ants just hardly making it past earth orbit in are rafts that is extremely costly and at most we gone to the moon.
Space cost does not seem to be coming done and it does not look like we will get any where in space other than the moon and mars with today's technology !!Well space mining and space colony is a pipe dream with today's technology.
Are there other options ( Has of now no !!! ) Please read.
- Anti-matter ( very very very costly (way more than chemical propulsion) , very hard to make and cannot be stored has fuele has we do not know how to store it yet.
-Ion or plasma does not have the thrust to lift any thing to space ( must be used for deep space not solution to get into space )
--Laser propulsion , pulse Laser very very costly and need gigawatt power.
--nuklear or fussion ( have not read up on this but the core and shielding would make it very big) not going help with payload problem.The cost to have a core and shielding may make more costly than chemical propulsion .
--nuklear Pulse very very costly to protect it from vibration to rocket.
--microwave propulsion very bad on the person health.
-- space elevator beyond todays technology !!
In the end it seems chemical propulsion is the only option to get into space
