Well chemical is very very very very very very much NOT fuel efficient of going into space and going in space cost so much most contries do not want to cough it up but the US,China and Russia.
Is there other option?
Has of now anti-matter is hard to make and cost is very very expensive and cannot be stored has a fuel .And laser propulsion or pulsed lasers will burn the hole through the earth and is very very expensive not to say Gigawatt power 20 times the capacity of the world's larges nuclear power plant.
And Ion and plasma propulsion does not have the thrust to take of from earth.And microwave propulsion is very bad on the health.
