B. Text of Launch Announcements.
GOES-J, named as GOES 9 after the launch, is an American
geostationary, meteorological spacecraft that was launched
from Cape Canaveral by an Atlas 1 rocket at 05:52 UT. It
will cover the central United States first but later will be
moved to cover either the east coast or the west coast. (Now
GOES 7 covers the west coast, and GOES 8 the west coast.) The
instruments on board will provide cloud cover images, and monitor
atmospheric temperatures and moistures at many altitudes.
SPEKTR, a Russian module to be docked with MIR station, was
launched from Baykonur cosmodrome by a Proton-K rocket at
05:33 UT. The 23.5 tonne spacecraft will remain with MIR
for at least three years. It carries a Belgian grating spectrometer
MIRAS that will monitor atmospheric gases such as ozone, carbon
dioxide, freon, and sulfur. It also carries some American equipments
to implement MIR-Shuttle rendezvous scheduled for later this year.
Initial orbital parameters were period 89.8 min, apogee 337 km,
perigee 221 km, and inclination 51.7 deg.
INTELSAT 706 is a geostationary communications spacecraft
of the INTELSAT consortium, and was launched from Kourou in
French Guiana by an Ariane rocket at 12:34 UT. The 4-tonne
spacecraft will be parked over the Atlantic ocean, and has the
capability to relay 110,000 telephone calls simultaneously.
USA 110 is an American military spacecraft that was launched by
a Titan-4 rocket from Cape Canaveral AFB at 13:45 UT.
ERS 2 is ESA's Earth resources spacecraft that was launched
by an Ariane rocket from Kourou Space Center in French Guiana
at 01:44 UT. The 2,516 kg spacecraft carries a synthetic aperture
radar for topographic studies, a wide beam radar (both in the
C-band), a radar altimeter for measuring ocean surface and waves,
a radiometer for measuring ocean surface temperatures, and an
optical Global Ozone Monitor (GOME) that will monitor ozone and
ozone-destroying gases and carries reflectors for laser tracking.
It has a 6.5 gigabit tape recorder to record data from a full orbit.
Initial orbital parameters of the Sun-synchronous orbit were
period 100 min , apogee 794 km, perigee 771 km, and inclination
GFZ 1 is a German microsatellite which was released from
the Russian MIR station. It carries reflectors for laser-ranged,
gravitational studies. Its orbital parameters are
presumed to be close to those of MIR. The international ID
is a derivative of the MIR ID, 1986-017A.
C. Spacecraft Particularly Suited for International Participation
- Spacecraft with essentially continuous radio beacons on frequencies
less than 150 MHz, or higher frequencies if especially suited for ionospheric
or geodetic studies. To see a list select here.
- Global Positioning System satellites useful for navigational
purposes and geodetic studies. To see a list select here.
*The GPS 2-NN series orbit in six distinct planes that are about 60 deg apart.
Each plane has four "slots." Following are the 2-NN members in the planes/
slots. The RAAN decreases by about 1.0 deg each month; below are their
24 May, 95 RAAN longitudes.
