B. Text of Launch Announcements.
STS 76 is an American shuttle spacecraft that was launched
from Cape Canaveral for docking with the Russian Mir station.
In addition to six astronauts, it carried also 2,400 kg of water
and 400 kg of scientific/engineering instruments for delivery to Mir.
One of the astronauts is expected to stay in Mir for 143 days
among the Russian cosmonauts. It docked with Mir on 24 March
and undocked on the 29th. The goals were endurance experience and
training experiences for building the hoped-for international
Alpha space station. Initial orbital parameters were period 92.5
min, apogee 411 km, perigee 389 km, and inclination 51.6 deg.
IRS-P3 is an Indian Remote Sensing spacecraft that was launched
by a 4-stage PSLV-D3 developmental rocket at 04:53 UT from
Sriharikota launch station at the southeast coast of India. The
930 kg spacecraft carried two remote sensing equipments and an
astronomical X-ray detector: WIFS (WIde Field Sensor) is a scanner
with visible light and infrared photometers to study crop conditions,
geology, and snow cover. The German Space Agencies (DLR's) modular
opto-electronic scanner will monitor oceanic chlorophyll, sediment
transport, and ocean dynamics. Data will be downlinked at three Indian
stations, and stations in Russia, Germany, and Mauritius. Initial
orbital parameters of the Sun-synchronous orbit were period 101.4
min, apogee 848 km, perigee 802 km, and inclination 98.7 km.
Cosmos 2331 is a Russian military spacecraft that was launched from
Plesetsk cosmodrome at 23:40 UT by a Soyuz-U rocket. Initial orbital
parameters were period 89.8 min, apogee 350 km, perigee 184 km, and
inclination 67.1 km.
INTELSAT 7-F7 is a geosynchronous communications spacecraft of
the INTELSAT consortium that was launched by an Ariane 44LP rocket
at 07:11 UT from Kourou in French Guiana. The 4,175 kg spacecraft
carries 26 C-band, and 14 K-band transponders to provide Europe and
the Americas three television channels and 22,500 telephone circuits
after parking over the eastern coast of Brazil.
REX 2 (Radiation EXperiment 2) is an American military mini-spacecraft
that was launched from Vandenberg AFB vicinity by a
Pegasus XL rocket at 01:33 UT; the rocket was carried aloft in the
belly of a L-1011 aircraft to 12 km altitude before release and
ignition. Initial orbital parameters of the 110 kg spacecraft were
period 101.2 min, apogee 832 km, perigee 801 km, and inclination
Polar is an American space physics spacecraft that was launched by
a Delta 2 rocket from Vandenberg AFB at 11:24 UT. The 1,300 kg pole-to-pole
orbiter carries 11 instruments to measure magnetospheric
hot plasma, electric/magnetic fields, plasma waves, X-rays and
energetic particles as well as visible light and UV cameras to map
auroral displays. The mission is a member of the international
ISTP/GGS fleet of spacecraft. Initial orbital parameters were period
938.1 min, apogee 50,551 km (over the Arctic), perigee 185 km, and
inclination 85.9 deg. A few days later the perigee was raised to
5,100 km through several gas burns.
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 orbits 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
approximate RAAN longitudes in November 95.
