Deatchable nose cone
Computer control cockpit for Martian Excursion Vehicle
Living accomodation and science laboratories on each side of the cockpit
Retractable rocket launcher
Abort mission emergency capsule
Rocket (each side) for jettisoning nose cone
Port twin antenna retracted
Lock-on mechanism securing the M.E.V to the main body
Retracted caterpillar tracks descend for planetary exploration
Command centre, for use when the M.E.V. has left the body in orbit
Retracted stub wing used to 'skip' main body clear of atmosphere if in grazing orbit
Undercarriage shown in retracted position
Radio remote control units and autopilots to control the lift-body when detached
Bank of five jets to control the manoeuverability of the lift-body on glide-path return
De-icing and refrigeration units on all leading surfaces
Fuselage removed to show the turboram-jet
Wing fuel tanks
Hydraulically operated elevators
Hinge enabling the wing tip to be in dropped position for take-off, so that the undercarriage, retracted against the booster jet, is at ground level
Booster jet
Main body – behind the passenger deck – a complex of fuel tanks and auxiliaries
Air intake and compressors; if it is necessary to use the main motors in the atmosphere, these allow air to be used as an oxidant, leaving the liquid oxygen in the fuel tanks for spacepropulsion
Firing chambers
Retracting tail fin
Bank of three main propulsion units
Bank of five secondary propulsion units
Firing chambers of the secondary bank of propulsion units
Retracted stub wing used to 'skip' main body clear of atmosphere if in grazing orbit
Air intake and compressors for the secondary bank of propulsion units
Second wing with lower bank of jets; in case of damage to the forward half of Zero X, the back half can detach itself just behind the forward wing at the main passenger deck, and continue independently
