B. Text of Launch Announcements.
Progress M-23, a Russian automatic cargo spacecraft, was launched
from Baykonur cosmodrome at 04:30 UT. The spacecraft delivered
2,207 kg of various supplies to the MIR station after docking on
May 24. Initial orbital parameters were period 88.6 min, apogee
247 km, perigee 192 km, and inclination 51.6 deg.
Gorizont 30, a Russian geostationary communications spacecraft, was
launched from Baykonur cosmodrome at 02:01 UT by a three-stage
Proton-K/DM-2 booster. It will be parked over the Asian Pacific.
It is the first of the fleet of seven spacecraft to be leased to the
U.S.-Malaysian RIMSAT company.
STEP 2 (Space Test Experiment Platform 2), a U.S.A. defense
spacecraft, was launched by a four-stage Pegasus rocket. It could
not attain exactly the planned orbital parameters. Initial orbital
parameters were period 99 min, apogee 834 km, perigee 606 km, and
inclination 81.9 deg.
MSTI 2 (Miniature Sensor Technology Integration 2), a U.S.A.
defense spacecraft, was launched from Vandenberg AFB by a Scout
rocket. It was the last of the now discontinued Scout series.
During an orbit it successfully spotted and locked onto a test
rocket launched from Edwards AFB. Initial orbital parameters were
period 92.8 min, apogee 469 km, perigee 367 km, and inclination
SROSS C2, a 113 kg Indian spacecraft, was launched by a ASLV-D4
test booster from Sriharikota station at 00:00 UT. It carried
a Retarding Potential Analyzer (RPA) for measuring ionospheric
plasma, and a Gamma ray detector. Initial orbital parameters were
period 98.1 min, apogee 917 km, perigee 433 km, and inclination
USA 103, a U.S.A. defense spacecraft, was launched.
Cosmos 2280, a Russian defense spacecraft, was launched from
Baykonur cosmodrome by a three-stage Soyuz-5 booster. Initial
orbital parameters were period 89 min, apogee 290 km, perigee
198 km, and inclination 70 deg.
Cosmos 2279, a Russian defense spacecraft, was launched from
Plesetsk cosmodrome by a Cosmos booster at 02:14 UT. Initial
orbital parameters were period 105 min, apogee 1,019 km, perigee
973 km, and inclination 83 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.

- Miscellaneous Items. (This section contains information/data that
are entered on occasion and may not be repeated in each issue of the
Erratum: In SPACEWARN Bulletin No. 486, it was erroneously
reported that STS 59 (1994-020A) radars were to map 46 square kilometers
of terrain They were to map 46 million square kilometers.
