B. Text of Launch Announcements.
GALS 2 is a Russian television relaying geostationary
spacecraft that was launched by a Proton-K rocket from Baykonur
cosmodrome at 14:25 UT. The 2.5 ton spacecraft carries three
multichannel high power transponders so that ground stations
in the far-eastern Siberia and the pacific coast countries can
capture signals with small dishes.
ISO (Infrared Space Observatory), an ESA spacecraft, was
launched by an Ariane rocket from Kourou base in French Guiana at
01:20 UT. The 2.5 tonne spacecraft of height 5.3 m and diameter
2.3 m carries a telescope with a primary mirror of 60 cm diameter.
The mirror feeds (a) a visual photopolarimeter at 2-245 microns,
providing images at 100-200 micron wavelengths through two cameras,
and spectra at 3-16 microns; (b) a camera to provide sky maps at
2.5-17 microns; and (c) a spectrometer at 2.5-45 microns. The 2,150
liters of liquid helium supply will enable about 20 months of
operation of all instruments. A few days after launch, the
orbital parameters were period 24 hr, apogee 70,500 km, perigee
1,000 km, and inclination 5.25 deg.
STS 74 is an American shuttle spacecraft that was launched
from Cape Canaveral to dock with the Russian space station, MIR. The
main mission was the docking exercise to transport to/from MIR about
500 kg of supplies. The docking module that was carried by STS 74
was successfully installed on MIR and remained after the end
of the mission whose purpose was to develop know-how's for building
a proposed international space station, Alpha. Initial orbital
parameters of the STS were period 92.4 min, apogee 396 km, perigee
391 km, and inclination 51.6 deg.
USA 115, also known as MILSTAR 2, is an American military
spacecraft that was launched from Cape Canaveral Air Station by a
Titan 4 rocket. The geostationary 4,500 kg spacecraft will be
parked at 4 deg, east longitude. Developed during the days of
nuclear war threats, the jam-proof and virtually disruption-proof
spacecraft has capability to transpond securely an extensive volume
of information with simultaneous access to a thousand users. Its
companion, MILSTAR 1, remains parked at 120 deg, west; four more
will join the constellation during 1999-2002.
SURFSAT (Summer Under-graduate Research Fellowship SATellite) is an
American microsatellite that was designed to assist tests on the
upgraded soft-/hardware at the Deep Space Network stations that
are primarily dedicated to capture the weak signals from
Heliospheric probes. The 55 kg spacecraft remained attached to the
second stage of the Delta 2 rocket (that had launched RADARSAT 1).
Initial orbital parameters were period 109.6 min, apogee 1,495 km,
perigee 935 km, and inclination 100.6 deg.
RADARSAT 1 is a Canadian remote sensing spacecraft that was
launched from Vandenberg AFB by a Delta 2 rocket at 14:22 UT. It
carries a synthetic aperture radar for mapping natural resources.
Initial orbital parameters were period 100.6 min, apogee 790 km,
perigee 785 km, and inclination 98.6 deg.
Cosmos 2322, a Russian military spacecraft, was launched by a
Zenit-2 rocket from Baykonur cosmodrome at 19:19 UT. Initial orbital
parameters were period 101.97 min, apogee 877.9 km, perigee 851.9 km,
and inclination 71 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 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.
