The ESA studied several concepts for a CRV: |

*Apollo-type capsule: This would have been a scaled-up version of the 1960s Apollo capsule, capable of carrying eight astronauts. A tower that sat on top of the capsule would contain a docking tunnel as well as the capsule's rocket engines, again similar to the Apollo configuration. The tower would be jettisoned just before re-entry. Landing would be via decelleration parachutes and air bags.<ref name="esa1"/> |
|||
*Also during Phase 1 studies the ESA looked at a conical capsule known as the "Viking". Like the Apollo-style, it would have reentered base first, but it had a more aerodynamic shape. The rocket engines for the "Viking" module were derivatives of the Ariane Transfer Vehicle. The design work continued until the end of Phase 1 in March, 1995.<ref name="esa1"/> |
|||
*A Blunt Biconic concept was studied in 1993 - 1994. This design was expected to be more maneuverable, but would have been heavier and more expensive.<ref name="esa1"/> |

CRV
ESA concepts
As a part of their wide ranging studies of potential manned spaceflight programs, the ESA began a 6-month first phase ACRV study in October, 1992. Prime contractors for the study were Aerospatiale, Alenia Spazio and Deutsche Aerospace.[1]
The ESA studied several concepts for a CRV:
- Apollo-type capsule: This would have been a scaled-up version of the 1960s Apollo capsule, capable of carrying eight astronauts. A tower that sat on top of the capsule would contain a docking tunnel as well as the capsule's rocket engines, again similar to the Apollo configuration. The tower would be jettisoned just before re-entry. Landing would be via decelleration parachutes and air bags.[1]
- Also during Phase 1 studies the ESA looked at a conical capsule known as the "Viking". Like the Apollo-style, it would have reentered base first, but it had a more aerodynamic shape. The rocket engines for the "Viking" module were derivatives of the Ariane Transfer Vehicle. The design work continued until the end of Phase 1 in March, 1995.[1]
- A Blunt Biconic concept was studied in 1993 - 1994. This design was expected to be more maneuverable, but would have been heavier and more expensive.[1]
