B. Text of Launch Announcements.

WSF 2, also known as Wake Shield Facility 2, is an American spacecraft that was released from STS 69. The wake region behind the disk-shaped, 1935 kg spacecraft would have been even more vacuous than the ambient region and could have enabled growth of slimmer thin-film semiconductors through molecular beam epitaxy technique during a planned two-day mission. The experiment had to be terminated and the spacecraft retrieved sooner than was planned due to overheating problems; the result of the experiment is unavailable at this time. Initial orbital parameters were close to those of STS 69.
SPARTAN 201, an Amereican spacecraft, was released from STS 69 at 15:42 UT. It carried X-ray, and far-UV, and visible light instruments to study the solar Corona and galactic clusters during its two-day mission. At the time of its retrieval, it was unexpectedly found to be spinning; it remains to be determined whether any usable data were collected during its free flight. Initial orbital parameters were close to those of STS 69.
STS 69 is an American shuttle spacecraft that was launched from Cape Canaveral at 15:09 UT. Its main mission was to release and recapture SPARTAN 201 and WSF 2. Initial orbital parameters were period 91.9 min, altitude 370 km, and inclination 28.4 deg.
Soyuz TM-22 is a Russian transport spacecraft that transported cosmonauts to Mir station for a 135 days stay. It was launched from Baykonur cosmodrome at 15:58 UT and docked at 17:30 UT on 5 September, 95 with Mir's KVANT-2 module, at the port that was vacated by Progress M-28 a day before. Initial orbital parameters were period 99.5 min, apogee 740 km, perigee 738 km, and inclination 69.9 deg.
SICH 1 is a Ukrainian remote sensing satellite that was launched from Plesetsk cosmodrome by a Tsiklon-3 rocket at 13:50 UT. The spacecraft and instruments on board are similar to those of the Soviet Okean series. Its main mission is to monitor objects of several hundred meters in size, such as Arctic ice. A second payload, FASAT-ALPHA, which is a Chilean spacecraft of 50 kg mass, could not be separated from SICH 1, and so had to be muted. Initial orbital parameters were period 98.7 min, apogee 682 km, perigee 651 km, and inclination 82.53 km.
Cosmos 2319 is a Russian geostationary, military communications spacecraft that was launched by a Proton-K rocket from Baykonur cosmodrome at 02:30 UT.
N-STAR-A is a Japanese geostationary communications spacecraft that was launched by an Ariane 4-P rocket from Kourou in French Guiana at 06:41 UT. The 3.4-ton spacecraft will enter the parking longitude of 132 deg, east.
JCSAT 3 is a Japanese communications spacecraft that was launched by a Delta rocket from Cape Canaveral at 00:53 UT. It carries eight transponders to provide 50 channels of digital television from its highly eccentric orbit. Initial orbital parameters were period 1,681.6 min, apogee 80,684 km, perigee 248 km, and inclination 23.1 deg.
