B. Text of Launch Announcements.

2009-034A
Sirius FM5 is an American communications spacecraft that was
launched by a Proton-M rocket with a BreezeM upper stage from Baikonur
at 19:10UT on 30June 2009. It will enable S-band digital radio
broadcasts (music, news, and entertainment) to motorists in North
America. SiriusFM5 will be placed in geostationary orbit at a longitude
of 96°W. The satellite has a design lifetime of 15years.

2009-033A
GOES 14, also known as GOES-O, is an American geostationary weather
satellite that was launched by a Delta4 rocket from Cape Canaveral at
22:51UT on 27June 2009. The mass of the spacecraft at launch was
3,200kg. It is the latest in the series of Geostationary Operational
Environmental Satellites which carry an imager, sounder, a Space
Environment Monitor package, a solar X-ray imager, and SARSAT Search and
Rescue ground-data relaying equipment. The SEM consists of an energetic
particle sensor, two magnetometers, and solar X-ray and extreme
ultraviolet sensors. GOES14 was placed in orbit originally as a spare.

2009-032A
MEASAT 3a, is a Malaysian geostationary communications satellite
launched on a Zenit-3SLB rocket from Baikonur on 21June 2009 at 21:50UT.
MEASAT3a will be placed into an orbital longitude of 91.5°E. The
satellite includes 12C-band and 12Ku-band transponders and will provide
telecommunications and video service to customers in the Asia-Pacific
region, the Middle East, and Africa. MEASAT3a will provide
direct-to-home programming to customers in Malaysia and Indonesia. The
satellite has a design life of 15years.

2009-031B
LCROSS, the Lunar Crater Observation and Sensing Satellite, was
launched as a secondary payload on an Atlas5 rocket from Cape Canaveral
on 18June 2009 at 21:32UT. LCROSS consists of a shepherding satellite
and the attached spent Centaur upper stage. The mission objective is to
send the Centaur upper stage into a lunar crater near the south pole of
the Moon and observe the impact. In particular, LCROSS will be looking
for signs of water in the debris plume. LCROSS carries two near-infrared
spectrometers, a visible light spectrometer, two mid-infrared, two
near-infrared and one visible light camera and a visible light
radiometer. Approximately four minutes after the Centaur impact the
shepherding satellite will also impact the Lunar surface. Several other
ground-based and space-based observatories are expected to observe these
events.

2009-031A
LRO, the Lunar Reconnaissance Orbiter, was launched on an Atlas5
rocket from Cape Canaveral on 18June 2009 at 21:32UT. LRO is a NASA
lunar orbiter mission intended to provide, from a polar orbit of 50km
altitude, high resolution maps of the lunar surface at several
wavelengths, altimetry data, and study permanently shadowed lunar
craters near the poles to search for signs of water ice. The primary
mission duration is one year with two or three more years in an extended
mission phase. LRO carries seven scientific instruments.

CRaTER (Cosmic Ray Telescope for the Effects of Radiation): A radiation
sensor that continuously measures the energetic particles from the Sun
and cosmic rays that reach the spacecraft to characterize the radiation
environment around the Moon.

DLRE (Diviner Lunar Radiometer Experiment): Remotely senses the lunar
surface to generate temperature maps of the Moon.

LAMP (Lyman Alpha Mapping Project): An instrument that uses Lyman alpha
ultraviolet starlight to search for ice in permanently shadowed craters.

LEND (Lunar Exploration Neutron Detector): A Russian detector to gauge
the hydrogen distribution of the Moon’s surface and the neutron
component of the radiation environment. The hydrogen could be an
indication of water ice.

LOLA (Lunar Orbiter Laser Altimeter): This laser altimeter will probe
the Moon’s topography and create precise 3-D maps of potential landing
sites.

LROC (Lunar Reconnaissance Orbiter Camera): Three-camera package for
detailed narrow- and wide-angle imaging. Two narrow-angle cameras will
make high-resolution, monochromatic images of the surface, with a
resolution down to 1m. Approximately 10% of the surface will be imaged
at this resolution. The wide-angle camera will take color and
ultraviolet images over the complete lunar surface at 100-m resolution.

Mini-RF (Miniature Radio Frequency Technology Demonstration): Synthetic
aperture radar technology demonstrator to image the polar regions for
evidence of water ice.

C. Spacecraft Particularly Suited for International Participation

Global Positioning System satellites useful for navigational purposes and geodetic studies.

High precision (<20 cm) GPS constellation tracking data obtained from
the network of about 400 dedicated global stations that are of interest
to geodetic study may be obtained through the following services
provided by the International GNSS Service . The IGS is a service of the
International Association of Geodesy .

The standard format of the GPS situation appeared in SPACEWARN Bulletin
No.518. It will not be repeated since an excellent source of trajectory-
and science-related GPS information is at:

It provides many links to GPS related databases.

The latest addition to the fleet is GPS 2R-20 (2009-014A).

Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation.

SPACEWARN requests updates/additions from readers to this list.

All GLONASS spacecraft are in the general Cosmos series. The Cosmos
numbers invoked by USSPACECOM have often differed from the numbers
associated in Russia; when different, the USSPACECOM Cosmos numbers are
shown in parentheses. The corresponding GLONASS numbers are Russian
numbers, followed by the numbers in parentheses that are sometimes
attributed to them outside Russia.

The operating frequencies in MHz are computed from the channel number K.
Frequencies = 1602.0 + 0.5625K and L2 = 1246.0 + 0.4375K.

The standard format of the GLONASS situation last appeared in SPACEWARN
Bulletin No.545. It will not be repeated in view of the excellent
updated source at: maintained by the
Information-Analytical Center , Russian Space Agency.

According to IAC the latest additions to the fleet are 2008-067A,
2008-067B, and 2008-067C.
