JOINT ESA-CNES PRESS RELEASE RE ARIANE 502 TEST FLIGHT

HR AMSAT NEWS SERVICE BULLETIN 306.01 FROM AMSAT HQ
SILVER SPRING, MD, November 2, 1997

BID: $ANS-306.01

Ariane 5, a new success story begins

The European new-generation launcher ARIANE 5 successfully
lifted-off today 30 October 1997 from the Guiana Space Centre,
Europe's Space Port, in Kourou, French Guiana at 10:43 a.m; Kourou
time (01:43 p.m. GMT, 02.43 p.m. CET) seven seconds after ignition of
the Vulcain engine that powers the main stage.

The two solid propellant boosters lifted the ARIANE 5 launcher
during the first part of the flight before separating from the main
stage. The fairing that shrouds the payload during ascent phase was
jettisoned three minutes after lift-off. Final injection was
performed by the storable propellant stage, which ignited ten
minutes after lift-off.

The first flight data from the launcher are under analysis. In-depth
analysis of flight data will be performed in the coming weeks at
CNES, the French space agency to which ESA has delegated management
of its ARIANE 5 programme, and by European contractors working on the
programme.

Twenty seven minutes into the flight MAQSAT H and MAQSAT B,
platforms carrying instruments to analyse launcher flight behaviour,
and the technology satellite TEAMSAT were ejected into orbit.

"Europe is once more in Space! This is another good example of what
European cooperation can do",  said ESA's Director General Antonio
Rodot  from the Launch Control Centre in Kourou "all those who have
consistently believed in Ariane, today have witnessed the start of a
new success story. But it's only the beginning, there is still a lot
of work ahead of us before this launcher can be made available to
users all over the world" added Rodot .

"We owed it to Europe and we have made it", echoed G rard Brachet,
Director General of CNES "the teams of experts, industry and all
involved in this launch in Europe and French Guiana have done a
great job. A further step towards qualification of the ARIANE 5
launcher has thus been taken, Bravo!".

This was the second test flight of ARIANE 5 after the failure of the
maiden flight on 4 June 1996. The third qualification flight, under
ESA and CNES reponsibility, is scheduled for spring 1998. Commercial
ARIANE 5 flights, managed by Arianespace, will then begin with the
fourth launch in the second half of 1998.

ANS thanks ESA for this information.

ARIANE 502 FLIGHT TEST UPDATE

HR AMSAT NEWS SERVICE BULLETIN 306.02 FROM AMSAT HQ
SILVER SPRING, MD, November 2, 1997

BID: $ANS-306.02

Ariane 5 Second Stage Engine Reportedly Shut Down Early

Despite the apparent successful flight of the Ariane 5 October 30, ANS

has learned from several sources that the test may not have been a
complete success.  It has been reported that the second stage shut
down
earlier than planned causing the payloads to go into lower than
expected
orbits.

The Ariane 502 vehicle was launched at 1343 GMT Thursday October from
Europe's launch center in Kourou, French Guiana, South America. The
payloads consisted of a pair of instrumented masses designed
to simulate simulate the masses of large communications and TV
satellites.

Data collected during the flight indicates that the liquid-fueled core

vehicle of the Ariane 5 rocket rolled in flight causing its Vulcain
main engine to shutdown 10 to 20 seconds earlier than planned.

Therefore, the upper stage booster and attached payloads (MAQSAT H and
B
plus TEAMSAT) did not attain the prescribed velocity and hence went
into
a lower orbit than expected.

In addition, ESA said that the liquid-fuel core vehicle fell to
Earth 5,000 miles from its projected impact site in the Pacific
Ocean. As a result, aircraft scheduled to witness the reentry were
unsuccessful in reaching area in time.

ESA officials are reported to have said that, had commercial
satellites been
aboard, their onboard propulsion systems would have enabled them to
attain
geostationary orbits, despite the lower than planned insertion. 
However,
it has been conceded that such a correction might have resulted in a
reduction
in the satellites' overall life, possibly up to 10 percent.

It is unclear what effect, if any, the lower orbit will have on
TEAMSAT; neither had its implications for Phase 3D, had it been
aboard.

A third flight test of Ariane 5 is presently scheduled for sometime
next
spring.

AMSAT CONGRATULATES ESA ON ARIANE-502 TEST FLIGHT

HR AMSAT NEWS SERVICE BULLETIN 306.03 FROM AMSAT HQ
SILVER SPRING, MD, November 2, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-306.03

Speaking for all the AMSAT organizations of the world, Dr. Karl
Meinzer DJ4ZC,
President of AMSAT-DL and Phase 3-D's Project Leader, has communicated
his
congratulations to ESA officials on the flight of Ariane 502.  He
termed the
test a success despite the anomaly associated with the early shutdown
of the
second stage engine and expressed confidence that the cause of this
difficulty
will be located and corrected prior to the Ariane 503 test flight.

ANS thanks Karl Meinzer DJ4ZC for this bulletin information.

TEAMSAT ANNOUNCES SUCCESSFUL LAUNCH

SILVER SPRING, MD, November 2, 1997

PRESS RELEASE  30/10/97 18:45

Teamsat has been successfully launched on the second qualification
flight of Ariane 5. The first data shows that the satellite is
working fine. ESA's operational centre (ESOC), has established
proper communication after a small delay.

The first high quality data from the cameras of the VTS (Visual
Telemetry System) experiment have been received and show clear images
of the Speltra structure with the Earth and its horizon as
background. Also the images of the AVS (Autonomous Vision System)
camera have been received. The communication with the subsatellite
YES, including GPS, has also been established.

About twenty young engineers from many European countries are
staffing the Experiment Control Centre that has been set-up at ESTEC,
the technical centre of ESA, using some twenty PC's with software
mostly developed by the young engineers themselves.

The young engineers are extremely pleased that after many months of
intensive work they are receiving such rewarding results. Not only
the "youngsters", but also the experienced staff and technicians of
ESA/ESTEC participate in the success of Teamsat.

The team will continue missions operation for approximately five
days, depending on the lifetime of the on-board batteries.

The first results will be presented, following validation by ESA, on
the Teamsat web page:

ANS thanks Peter Guelzow DB2OS for relaying this information.
