B. Text of Launch Announcements.
Molniya 1-87, a Russian communications spacecraft, was launched
from Plesetsk cosmodrome at 23:37 UT by a Molniya carrier.
Initial orbital parameters are period 11 hr, 43 min; apogee
39,206 km; perigee 446 km; and inclination 62.8 deg.
THAICOM-1, a Thailand geostationary, communications spacecraft,
was launched by an Ariane 44-L booster from Kourou, French
Guiana, at 01:27 UT and parked a little eastward of that country.
It carries ten C-band and two KU-band transponders.
DBS-1, a U.S.A. geostationary, communications spacecraft for high
resolution TV broadcast, was launched by an Ariane 44-L booster
from Kourou, French Guiana, at 01:27 UT. It will cover the U.S.A.
and many American countries.
TELSTAR 401, a U.S.A. geostationary, communications spacecraft,
was launched by an Atlas 2AS rocket from Cape Canaveral.
USA 98, a second of the NATO's NATO 4 series of encrypted
communication satellites, was launched from Cape Canaveral by a
Delta 2 rocket. Initial orbital parameters are period 645 min,
apogee 33,913 km, perigee 737 km, and inclination 23.2 deg.
STS 61, a U.S.A. shuttle spacecraft, was launched from Cape
Canaveral. It was a mission to repair or update the instruments
on the Hubble Space Telescope. During several days of EVA, the crew
installed corrective optics (COSTAR) in the light path after
vacating the High Speed Photometer instrument; replaced the
older Wide Field Planetary Camera (WF/PC) with a newer version,
WF/PC 2; and replaced malfunctioning solar arrays. Initial
orbital parameters are period 96.5 min, apogee 594 km,
perigee 588 km, and inclination 28.4 deg.
USA 97, a military communications spacecraft, was launched from
Cape Canaveral by an Atlas-Centaur rocket. Initial orbital
parameters are period 623.3 min, apogee 35,533 km, perigee 160 km,
and inclination 26.5 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 269 2-21 2-12 2-15 2-04
B 329 2-18 2-07 2-02 2-22
C 29 2-23 2-13 2-19 2-20
D 89 2-11 2-09 2-05 ----
E 149 2-01 2-08 2-03 2-10
F 209 2-16 2-14 2-06 2-17
- Actual decays/landings of payload spacecraft and rocket bodies (R/B)
only. Additional information is not available.
