EXOMARS

• Ground based testing
• Numerical modelling
• Contribution to
• aerothermodynamic data base

13
EADS Astrium

• ARV (Advanced Re-entry Vehicle)
• Phase A until next ministerial conference in 2011
  has been initiated
• capsule type vehicle using mainly existing
  technologies
• the scenario foresees in a first step an unmanned
  mission to ISS
• in a second step also a manned mission is planned
  giving Europe the autonomous capability for crew
  transport
• further evolution for moon mission is envisaged

• Space plane
• Astrium initiative for space tourism
• Pre-development phase was completed for a
  sub-orbital vehicle

14

• Manned LEO Exploration Missions need safe
  comfortable Earth re-entry, up to superorbital
  speeds for nominal and emergency return
• Operational flexibility, safety comfort desires
  High-Lift-over-Drag Vehicles
• Survey of already existing innovative re-entry
  strategies
• Description of potential launch strategies
  landing sites
• Selection of suitable vehicles fulfilling the
  reference re-entry aerodynamic
  aerothermodynamic
• Presentation of Flight mechanics
• Guidance strategies with description of the
  benefits of such high L/D Vehicles
