The Aurora company has unveiled the new Interplanetary Airliner (usually simplified to space shuttle) offering both affordable and comfortable space travel to the middle and upper classes of the Hegemony. The Aurora shuttles would be capable of taking passengers from earth all the way to space and beyond.
What fuel could be used for a space shuttle to be able to go from a runway on earth into space? The fuel would have to be affordable as well as rather powerful.
Maximum distance for a flight would be from Earth to Luna or Earth to Eros.
In most cases flights dock with a space station and passengers board a ship more suited for long distance travel
Fuel that is plausible in the near future is alright
