COMEX (Compagnie Maritime d’Expertises)
specialised in engineering solutions for extreme
environments, maritime, and undersea operations,
and Zero 2 Infinity (Z2I), the only private
company in Europe specialised in enabling
access to Space with high altitude balloons, have
partnered to offer cooperative stratospheric
balloon launches.
You can now launch scientific or commercial
payloads to the stratosphere for a reduced cost.
The combination of several payloads into one
single flight offers the possibility to reduce the
price to a level that can be easily accessible by
various organisations and companies.
The payloads are launched by the Z2I team
off-shore Marseilles, in the Mediterranean, from
COMEX’ launch vessel “JANUS II” to an altitude
of between 20 and 40 km. The payload is recovered
in the sea by our teams after its descend
with a parachute.

Mission Profile
and includes pre-tests at dedicated
facilities. Our team will support payload
development in order to be integrated in
the C-Launch flight platform.
One month before the mission,
splash-tests, and immersion tests will be
done to assure that the system can
survive the return to Earth. 6h before the
launch, all mission teams will embark on
JANUS II and last checks will be performed.
The balloon will be launched from
JANUS II flight deck and will fly for
around 2h to the stratosphere. After
mission termination, the payload will
return to the Earth by parachute and
land in the sea. The system will be
recovered by our teams with the help of
a tracking system.

The concept of launching high altitude balloons from the sea has several advantages compared to launches from land:
better cope with weather. A vessel
dynamically adapts to the low altitude
winds so that the balloon can be released
with security (zero relative wind). Launch
windows are therefore increased, which
also decreases mission cost.

oceanographic research vessel that
serves as launch platform for C-Launch.
The ship has enough space to host a crew
of 18 for several days. JANUS II also acts
as the control centre for tracking the
balloon and as the recovery ship. The
vessel includes work areas, a meeting
room, and sleeping cabins.

Zero 2 Infinity has a track record of more
than 30 launches of different payload
sizes, from a few kilos to half a ton. The
payloads have different purposes:
educational, marketing, satellite testing,
component qualification, drop-tests, and
scientific and research activities.
Z2I has nine years of experience
performing ground and sea flight
campaigns. Discover more about Z2I at
