a wide range of topics from the simplest operations with an HT to some of t=
he
latest ideas on digital communications. Every orbit; LEO, MEO, Geo and bey=
ond
will be covered. There will also be an extended general membership meeting =
as
well as the ever popular Field Ops Breakfast.
Martha reminds everyone that room block with the =
special $125 per night rate for
the 2008 AMSAT Space Symposium will be gone on October 8th. PLEASE make yo=

Michael Chen, BD5RV/4, reports that he recently received an update from Ala=
n,
BA1DU, on the progress of the first Chinese amateur satellite. Things are =
now
going smoothly. This satellite was formerly named CAS-1 and is now XW-1. It
carries a beacon and three cross band transponders: FM, linear, and digital.
The satellite is planned to be launched into a Sun synchronous orbit in June
2009 by a CZ-2C rocket in Taiyuan Satellite Launch Center in North China.

Version 0.4.0 of the General Astrodynamics Library has been released.
It can be downloaded from the project website here:
http://homepage.mac.com/pclwillmott/GAL/index.html
Updates in this release:
Higher precision ephemerides for the Sun, Planets, and Pluto.
Implemented using VSOP87. Heliocentric and barycentric routines for
position and velocity provided.
Support added for classical Keplerian models, circular, elliptical,
parabolic, and hyperbolic orbits and trajectories supported. Keplerian
propagation implemented using the Universal formulation.
Release includes some additional support files, and minor updates.
Work continues with the atmosphere, and remaining force models.
The General Astrodynamics Library (GAL) is a numerical library for C
and C++ programmers. It is free software under the GNU General Public
License.
The library provides a wide range of astrodynamical routines such as
ephemerides, earth orientation, and orbit propagation. There are over
250 functions in total with an extensive test suite.

Space Exploration Technologies Corp. (SpaceX) announces that Flight 4 of the
Falcon 1 launch vehicle has successfully launched =
and achieved Earth orbit. With
this key milestone, Falcon 1 becomes the first privately developed liquid f=
uel
rocket to orbit the Earth.
"This is a great day for SpaceX and the culmination of an enormous amount of
work by a great team," said Elon Musk, CEO and =
CTO of SpaceX. "The data shows we
achieved a super precise orbit insertion=97middle of the bull's-eye =97 and=
then
went on to coast and restart the second stage, which was icing on the cake."
The Falcon 1 lifted off at 4:15 p.m. (PDT) / 23:15 (UTC) from the Reagan Te=
st
Site (RTS) on Omelek Island at the U.S. Army Kwajalein Atoll (USAKA) in the
Central Pacific, about 2,500 miles southwest of Hawaii.
Preliminary data indicates that Falcon 1 achieved an elliptical orbit of 50=
0 km
by 700 km, 9.2 degrees inclination=97exactly as targeted.
Falcon 1 carried into orbit a payload mass simulator of approximately 165 kg
(364 lbs), designed and built by SpaceX, specifically for this mission.
Consisting of a hexagonal aluminum alloy chamber 1.5 meters (5 feet) tall, =
the
payload remains attached to the second stage as it orbits Earth.
