After lying dormant for very nearly 14 years, Kourou's first ever
launch pad is about to be resurrected. On 3 June, a delegation of
companies involved in the Vega launcher programme visited the ELA-1 site
which saw the very first Ariane liftoff in December 1979.
ESA's new
small launcher Vega schedules a first flight from the reconverted ELA-1
pad in July 2006. The vehicle will complement Ariane 5 and Soyouz. Vega,
30 m tall and a lift-off mass of 130 tons, will be able to launch
small-medium sized satellites up to 1500 kg into low-Earth orbit. Work is
shortly to begin adapting the site which was last used by an Ariane 3
vehicle on 12 July 1989.

Although the ELA-1 service tower and gantry were demolished in June
1991, the actual launch pad with its flame pit, exhaust ducts and
onion-shaped water tower near-by had been kept. The historic site had been
abandoned and occasions to visit it in recent years have been
rare.
The completion phase of the Italian-led Vega programme was
launched on 25 February last when ESA signed a contract with the ELV S.p.A
company. ELV S.p.A. with its two shareholders FiatAvio (70%) and the
Italian Space Agency (30%) is the programme prime contractor. A second
contract had been signed between CNES, on behalf of ESA, with FiatAvio for
the development of the launcher's P80 advanced solid-propulsion first
stage.

The decision to use the former ELA-1 pad was taken in November
2001. This solution was prefered to an alternative of jointly using the
ELA-3 launch zone with Ariane 5. However the two launchers will share one
common facility: the Vega launch operations center will be in the CDL-3
center which was built for Ariane 5. The CDL-2 launch centre was closed
after the last Ariane 4 launch last February. The building will however
accomodate the Vega programme teams.

At the invitation of the European Space Agency, which for the first
time is exercising its newly-acquired prerogative of direct control of
launcher programmes, some 30 companies took part in the 3 June visit, 17
of them from Europe. Alongside representatives from lead-country Italy,
were engineers and management from companies in France, Belgium, the
Netherlands, Spain, Switzerland and Sweden. Many of the participants were
civil engineering and ground infrastructure companies (air-conditionning,
electricty, water supplies..) who expect to be bidding for contracts when
ESA calls for submissions later this year. Work is expected to start next
September.

They were able to see at close-quarters the different aspects of the
old pad, and examine practical aspects of the rehabilitation programme
that has been conceived. Much of the existing infrastructure, such as the
launch clamps which held the first Ariane vehicles to the ground before
liftoff, will be dismantled and replaced by more modern Vega-specific
mechanisms.
The assembly of Vega's four stages will take place on
the renovated launch zone itself in a new mobile assembly building, which
like the former ELA-2 gantry, will roll back to allow
launches.

The Vega programme represents some 335 Million euro, of which 45 Meuro
will be for the new ground installations including the ELA-1 renovation.
After first tests at the start of 2005, a first qualification flight,
which could take place in July 2006, accounts for 30 Meuro. The parallel
P80 stage development totals 123 Meuro with FiatAvio paying
half.
The Vega visit on June 3 was covered by the local press and
media. The event was more significant than just the resurrection of the
historic pad. It symbolised the start of new activities for the space
port. Kourou staff has been hard hit by the drop in the number of Ariane
launches scheduled for future years. For French Guiana, the prospect of
Vega, together with the advent of Soyouz and its purpose-built launch zone
along the coast, are the silver lining of the past months' dark clouds.
