B. Text of Launch Announcements.
Cosmos 2327 is a Russian military spacecraft that was launched
from Plesetsk cosmodrome by a Cosmos-3M rocket at 15:34 UT. Initial
orbital parameters were period 104.9 min, apogee 1,034 km, perigee
974 km, and inclination 83 deg.
KOREASAT 2, also known as MUGUNGHWA 2, is a South Korean
geostationary communications spacecraft that was launched from Cape
Canaveral by a Delta 2 rocket at 11:10 UT. It will be parked at
116-E longitude over Borneo island to provide broadcasting and
telecommunications to South Korea, beginning July 96.
MEASAT 1 is a Malaysian geostationary communications spacecraft
that was launched by an Ariane 44L rocket from Kourou in French
Guiana at 23:10 UT. After parking at 91.5-E longitude, the
1,450 kg spacecraft will provide communications and direct-to-home
television services to Malaysia and neighboring countries through
its four Ku-bands and 12 C-band transponders.
PAS 3R, also known as PANAMSAT 3R, is an American geostationary
communications spacecraft that was launched by an Ariane 44L rocket
from Kourou in French Guiana at 23:10 UT. After parking at 43.0-W
longitude, the 2,900 kg spacecraft will provide TV and communication
services to the north- and south American countries through its 16
OAST FLYER ( NASA's Office of Aeronautical and Space Technology
flier) is an American minispacecraft that was released from
the shuttle STS 72. It carried four experimental packages: to measure
spacecraft contamination levels at low-Earth orbits, to test GPS
equipments, to test amateur radio gears, and finally to determine the
effect of solar radiation on the explosives aboard satellite systems.
Initial orbital parameters were period 90.6 min, apogee 310 km,
perigee 302 km, and inclination 28.4 deg.
STS 72 is an American shuttle spacecraft that was launched from
Cape Canaveral at 09:41 UT. It carried, released, and retrieved
the OAST FLYER. It also retrieved a long orbiting Japanese reusable
spacecraft, SFU that had amassed astronomical data and material
science products since March 1995. Initial orbital parameters were
period 91.1 min, apogee 470 km, perigee 185 km, and inclination
XTE (X-ray Timing Explorer) is an American astronomy spacecraft that
was launched by a Delta-2 rocket from Cape Canaveral AFS at 13:48
UT. The 3,000 kg spacecraft carries three major instruments with
large collecting areas, wide bandwidths, and high resolution. The PCA
(Proportional Counter Array, of NASA/Goddard) consists of five
xenon counters of area 7,000 sq-cm, field-of-view 1.0 deg, bandwidth
2-60 keV, resolution 1.0 microsecond, and sensitivity 0.1 milliCrab;
the HEXTE (High Energy X-ray Timing Experiment of UC-San Diego)
contains eight sodium/cesium iodide crystals of area 1,600 sq-cm,
field-of-view 1.0 deg, bandwidth 20-200 keV, resolution 10
microsecond, and sensitivity 1.0 milliCrab; the ASM (All Sky
Monitor of MIT) is an array of three xenon proportional counters of
area 90 sq-cm, field-of-view 6 deg x 90 deg, bandwidth 2-10 keV,
resolution 1.5 hr, and sensitivity 20 milliCrab. One Crab is the
intensity of x-ray emission from the Crab nebula. Unlike the
telescopes PCA and HEXTE, the ASM scans most of the sky every 1.5
hr in order to monitor about 75 bright sources; the positional
resolution of ASM is about 0.05 deg x 0.25 deg. (Problems with the
scanning mechanism are now being addressed.) Initial orbital
parameters were period 96.1 min, apogee 583 km, perigee 565 km, and
inclination 22.9 deg. Status of the experiments and some data may be
accessed through the URL:
ECHOSTAR 1 is an American geostationary communications spacecraft
that was launched by a Long March 2E rocket from Xichang Center in
Sichuan province, PRC at 11:51 UT. The 3,288 kg spacecraft carries
16 Ku-band transponders to enable direct broadcast communications
and television channels through 0.5 meter dishes on the ground in
the American continents.
SKIPPER is a small American science spacecraft that was launched
by a Molniya-M launcher from Baykonur cosmodrome at 06:45 UT. It
has been reported to be a "sub-satellite" (of IRS 1-C), but no
details are currently available on the Utah State University
instrumentation package. Initial orbital parameters were period
101.0 min, apogee 813 km, perigee 803 km, and inclination 98.6 deg.
IRS 1-C (Indian Remote Sensing satellite) is the third of the Indian
natural resource imaging satellites and was launched by a Molniya-M
launcher from Baykonur cosmodrome at 06:45 UT. The 1,250 kg
spacecraft carries three instruments: PAN (PANchromatic camera of
6-meter resolution), multispectral LISS-3 (Linear Imaging
Self-Scanner), and WIFS (WIde Field Sensor). Images from regions
other than India will be downlinked and distributed through a
commercial entity in USA. Initial parameters of the Sun-synchronous
orbit were period 101.2 min, apogee 818 km, perigee 816 km, and
inclination 98.6 deg.
