Ariane 5
Successfully Launches Mtg-I1 Satellite For
Eumetsat And Two Galaxy Satellitesfor
Intelsat
On Tuesday, December 13th, 2022
at 05:30 pm local time, an Ariane 5 launcher,
operated by Arianespace, successfully lifted off
from Europe’s Spaceport in Kourou, French Guiana
(South America), carrying the MTG-I1 meteorological
satellite and the Galaxy 35 and Galaxy 36
telecommunication satellites.
The Meteosat Third Generation
(MTG) system will help meteorologists meet one of
their main challenges – the rapid detection and
forecasting of severe weather events – so that
timely warnings can be given to citizens, civil
authorities and first responders. The data from
MTG-I1 (the “I” stands for “Imager”) will have a
wide range of uses, from enabling aircraft to avoid
storms and earlier alerts of flooding, to more
precise monitoring of fires and fog. It will help to
protect lives, property and infrastructure and bring
economic benefits to Europe and Africa. The MTG
satellites are developed and procured in cooperation
with the European Space Agency by an industrial
consortium led by Thales Alenia Space and OHB. The
satellites are developed according to the
requirements defined by EUMETSAT after consultation
with the users of its meteorological data.
Galaxy 35 and Galaxy 36 are the
next satellites in Intelsat’s comprehensive Galaxy
fleet refresh plan, a new generation of spacecraft
that will provide Intelsat media customers in North
America with high-performance media distribution
capabilities and unmatched penetration of cable
headends.
These two satellites will bring
C-band contribution capacity to support high-profile
events, such as collegiate and professional
football, auto racing, baseball, golf, boxing and
professional wrestling.
The satellites also offer
in-orbit protection for select customers in the
broadcast arc serving North America.
“With the successful launch of
VA259, Arianespace is proud to serve the interests
of EUMETSAT and Intelsat, two operators with whom we
have been working since 1981 and 1983,
respectively”, said Stéphane Israël, CEO of
Arianespace. “This mission serves both Europe and
North America and is a perfect illustration of the
versatility of our heavy-lift launcher, which is
capable of meeting the needs of both institutional
and commercial operators. Its passengers also
reflect our own values, which are to make Space work
for a better life on Earth, by improving our
meteorological knowledge and connectivity.”
“For its last flight of the
year, Ariane 5 once again demonstrated its power and
competitiveness, achieving a new performance of
almost 11 tons to geostationary orbit. It also
proved its responsiveness to the needs of
Arianespace’s customers, by launching three
satellites at once. Only two more Ariane 5 remain to
be launched. The teams at ArianeGroup and
Arianespace, with the support of ESA and the French
space agency CNES, are preparing together for Ariane
6’s entry into service in autumn 2023”, said
André-Hubert Roussel, CEO of ArianeGroup.
By delivering 10.972 tons to
geostationary orbit, Ariane 5 achieved its second
highest performance after the launch of Syracuse A4
and SES-17 in October 2021. The Ariane 5 was adapted
for this mission so that it could accommodate three
satellites under its fairing. This triple
configuration is made possible by a raising cylinder
and a long fairing, increasing the space allocated
to the satellites by 20m3. This is the third time in
its history that Ariane 5 has done a triple launch.
After this mission, just two
Ariane 5 launches are left, including the JUICE
mission, before Ariane 6 takes up the baton,
supporting Europe’s institutional missions and
meeting the growing needs of the commercial market.
The Ariane 5 heavy-lift
launcher is an ESA program carried out in
cooperation between public institutions and industry
across 12 European partner states. The launches are
operated by Arianespace.
ArianeGroup is the lead
contractor for the development and production of
Ariane 5, as well as being responsible for launcher
preparation operations up to lift-off. As prime
contractor for Ariane 5 and Ariane 6, in charge of
development and production, ArianeGroup is at the
head of a vast industrial network of more than 600
companies, including 350 small and medium-size
enterprises (SME).
ArianeGroup delivers a
flightworthy launcher on the launch pad to its
subsidiary Arianespace, which sells and operates
Ariane 5 from the Guiana Space Center (CSG) in
French Guiana. During launch campaigns, Arianespace
works closely with the French space agency (CNES),
which is the design authority for Ariane 5 and is
responsible for the satellite preparation facilities
and the launch base.
