A beautiful artwork of Hermes on the launchpad taken from a October 1979 magazine .
The variant of the spaceplane depicted here is the
original version presented by CNES at the Paris Airshow the previous spring.
Interestingly, the launch vehicle envisioned is an
Ariane 1. The maiden flight of that rocket was just 2 months after the
issue of the magazine and this may have influenced the artist.
However,
in no way an Ariane 1 would have been able to throw Hermes in orbit.
The first operational rocket of ESA was designed to deliver payloads in
GTO (1 800kgs) not to LEO. But even with a reduced 3rd stage, the
booster capability would have never fit with the 10 tons mass of Hermes.
Instead, CNES planned to use an uprated version of
Ariane 4, dubbed "Ariane 5" with an enlarged 2nd stage. That rocket
would have been very different from the Ariane 5 that will eventually be
built and fly 15 years later.
