B. Text of Launch Announcements.
IRS-P2, an Indian Remote Sensing spacecraft, was launched by
a four-stage PSLV-D2 rocket from Sriharikota launch center
in southeastern India at 05:08 UT. The 870 kg spacecraft is
in a Sun-synchronous orbit, is stabilized triaxially, and carries
a linear imaging self-scanner camera in a Sun-synchronous orbit.
The images will be marketed through a private company in the U.S.A.
Initial orbital parameters were period 98.7 min, apogee 881 km,
perigee 804 km, and inclination 98.7 deg.
Express 1 is a Russian geostationary communications spacecraft
that was launched by a Proton-K booster from Baykonur cosmodrome.
The Express series will replace the currently orbiting Gorizont
series of geostationaries and has a 12-channel capability instead
of the eight channels in Gorizont.
Okean 01 is a Russian/Ukrainian oceanic/meteorological spacecraft
that was launched from Plesetsk cosmodrome by a Tsiklon rocket at
13:30 UT. This may be one of the last of the Tsiklon launches since
it uses highly toxic fuel. Initial orbital parameters were period
82.5 min, apogee 663 km, perigee 628 km, and inclination 97.6
THAICOM 2 is a Thailand geostationary communications spacecraft that
was launched by an Ariane 4 rocket at 01:07 UT from Kourou in French
Guiana. The 600 kg spacecraft carries ten transponders in
C-band and two in Ku-band. It is expected to serve Thailand and
Solidaridad 2 is a Mexican geostationary communications spacecraft
that was launched by an Ariane 4 rocket from Kourou in French Guiana
at 01:07 UT. The 1600 kg, 2,500 Watt spacecraft carries 18
transponders in C-band with a total 35-channel capability in the
C-, L-, and Ku-bands.
INTELSAT 703 is a geostationary communications spacecraft that was
launched from Cape Canaveral by an Atlas 2As rocket at 06:35 UT.
The 4,000 kg spacecraft carries 26 C-band and ten Ku-band
transponders that can sustain more than 18,000 simultaneous two-way
telephone calls and three TV channels for countries in the northern
Soyuz TM-20, a Russian spacecraft, was launched from Baykonur
cosmodrome to transport a crew of Russian/European cosmonauts and
experimental apparatus to the Mir station. Automatic docking proved
troublesome for several minutes, and the module had to be coaxed
manually by the crew commander to dock. Initial orbital parameters
were period 89.8 min, apogee 305 km, perigee 228 km, and inclination
STS 68 is a U.S.A. shuttle that was launched from Cape Canaveral. It
carried the Space Radar Laboratory (SRL) containing SIR-C, a dual
polarization radar at C- and L-bands, X-SAR, an X-band vertical
polarization radar, and MAPS, an infrared sensor for measurement of
air pollution. Initial orbital parameters were period 88.9 min,
apogee 226 km, perigee 213 km, and inclination 57.0 deg.
Cosmos 2292 is a Russian military spacecraft that was launched from
Plesetsk cosmodrome by a Cosmos-3M rocket at 13:00 UT. Initial
orbital parameters were period 108.6 min, apogee 1,973 km, perigee
408 km, and inclination 82.6 deg.
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 60 deg apart.
Each plane has four "slots." Following are the members of the planes/slots:
PLANE RAAN OF PLANE SLOT-1 SLOT-2 SLOT-3 SLOT-4
A 256 2-21 2-12 2-15 2-04
B 316 2-18 2-07 2-02 2-22

E 136 2-01 2-08 2-03 2-10
F 196 2-16 2-14 2-06 2-17
- Russian Global Navigational (Positioning) Spacecraft, GLONASS
constellation. To see a list select here.
- Actual decays/landings of payload spacecraft and rocket bodies (R/B)
only. Additional information is not available.
