Just another nag that the AMSAT election for members of the Board of
Directors is in progress. The end of the summer, and the start of school is
upon us. Still, if you haven't gotten around to it, take a few minutes to
vote. The deadline will be here in a month. Obviously it is important as a
member to vote, but it is also important for Board members to receive your
input in this way.
73s,

ARISSat-1 update
We are now manifested on Progress 41P to get ARISSat to the ISS. The current
timeline has the launch in January 2011. Four ARISSat satellites have been
assembled in Orlando. The two Russian flight units are assembled,
electronics are undergoing operational tests, software is close to being the
final version and we expect to have the satellite complete and ready for
vibration tests next week. We don't have a date for the vibration test yet,
but are working to get one in the next few weeks. NASA has been very
instrumental in getting us an export license, arranging for transportation
to Russia and helping clarify how the satellite will be attached to the
Progress vessel. We plan on shipping the two satellites to Russia in
September, to give them time to install the Kursk experiment, test their
battery with the satellite and do additional tests before shipping to
Baikonur for launch.

Reminder: Symposium Call For Papers Deadline is Coming
It's already August 1 and the September 1 deadline of the call for
papers for the 2010 AMSAT Space Symposium and Annual Meeting is
approaching faster than ever! The abstracts and some completed
papers have arrived - thank you. For everyone else - we need to
get busier ... please!
The abstract for your paper does not require any special format.
Simply send an e-mail to the Proceedings Editor, K9JKM with the
basic information: Author Name, Callsign, and a few sentences that
describe your proposed topic. I'll be looking forward to receiving
your abstracts in my in-box at k9jkm@comcast.net.
The Symposium Committee invites proposals for:
+ Papers for publication in the Proceedings
+ Symposium Presentations
+ Poster Presentations
+ Equipment and Operating Demonstrations
These can be on any topic of interest to the amateur satellite
community. We request a tentative title of your presentation as
soon as possible, with final copy submitted by September 1, 2010
for inclusion in the printed proceedings.
To help you prepare your paper the Symposium Committee has posted
an author's guide on the AMSAT.org web page:

The 2010 AMSAT Space Symposium and Annual Meeting will be held
October 8 - 10 at the Chicago/Elk Grove Holiday Inn which is near
O'Hare Airport.

Eclipses Cause Short Term Changes to AO-51 Schedule
AO-51 Command Team member, Mark N8MH noted this week that AO-51 is
still in eclipses until the last week of August. The satellite will
be back in 100% sun until the end of December after this time. That
means the Command Team should be able keep AO-51 transmitting all
the time. In fact, they will need to do this in order to keep temp-
eratures down!
In recent days the Command Team had to resort to shutting down the
voice repeater in order to grab some telemetry files from the bird.
This was very important as we are nearing the end of the eclipse
period and was a unique opportunity to collect good data for current
use and for future reference for AO-51 Operations.
Recently AO-51 has been automatically turning itself OFF and back
ON because of the power budget. Users see this more often as it
first comes out of eclipse and as it begins to enter eclipse. The
Command Team will continue to fine tune this, but the goal is to
keep AO-51 transmitting when there is enough power--without having
the bird shutdown until manually commanded back ON by one of the
command team members.
Starting January 2011, we won't see much of a break from the eclipse
periods for a long, long time (there is one short window of full sun,
but it's about 2 weeks long in late Feb/early March 2011). The com-
mand team has been using the recent eclipse period to learn how to
become more efficient in the use of the power management code on board.
This allows us to get the most "bang for the buck" out of the available
power. It's pretty complex and versatile. We've learned a tremen-
dous amount this eclipse period, but still have more to learn in
the future.

1. Upcoming School Contact
An Amateur Radio on the International Space Station (ARISS) contact has been
scheduled with the DaVinci Science Center in Allentown, Pennsylvania. The
Center has integrated this activity into its Summer Camp Program for 2010.
Students have learned about space through lessons from the NASA Goddard
Space Flight Center Education Office and Astronaut Terry Hart is expected to
give presentations. The Delaware-Lehigh Amateur Radio Club has provided
instruction on Amateur Radio, how it works, what it is and its uses, how the
ARISS radio systems work, the international ham radio team, satellite
tracking, radio wave propagation and the organizations that sponsor ARISS.
The club will also provide VHF demonstrations and multi-media presentations
to the group which will enhance the center's 200 hands-on exhibits that
promote the understanding of science and technology. Due to ISS Problems,
This has been postponed, however, keep informed as this can change before
this ANS is published.
2. QST Covers ARISS
The American Radio Relay League (ARRL) September issue of QST carried an
item in the "Inside HQ" column about how NASA ISS crew members participated
in one or more ARISS educational activities per week during the first half
of 2010. The ARRL monthly journal has a circulation of 150,000.
3. ISS Ham Debrief Scheduled
An Amateur Radio on the International Space Station (ARISS) debrief session
has been scheduled with Expedition 22/23 astronaut Soichi Noguchi, KD5TVP on
Tuesday, August 17. The feedback provided on the radio system and school
contacts will help the ARISS program update its operations.

SA-AMSAT Reports Plans for Sumbandilasat SO-67 Return to Service
South Africa AMSAT (SA-AMSAT) is slowly adding additional operational
time for Sumbandilasat SO-67. On their web page they report that the
ground control station will start slowly with the amateur payload and
observe if the satellite remains stable and then gradually add more
operating time. The current SO-67 schedule for operations over South
Africa and Europe can be found on their web page at:
http://www.amsatsa.org.za/
The PTT of the transmitter now STAYS ON for the duration of the payload
activation (i.e. 15 min), regardless of a valid "transponder" tone
received. Please leave a 3 second gap between overs.

Japan's Venus Mission Getting Close
The mission that launched UNITEC-1, Amateur Radio's first inter-
planetary probe, the Venus Climate Orbiter also known as Akatsuki
remains healthy and is nearing the planet. The 5.8 GHz amateur radio
beacon from UNITEC-1 was last heard only two days outbound from Earth.
Akatsuki, bristling with cameras, will circle the exotic planet's
equator in an elliptical orbit for at least 2 years, monitoring the
atmosphere at different altitudes using various wavelengths (IR, UV,
and visible). With this data and data from the spacecraft's radio
dish, scientists will reconstruct a 3D model of the atmosphere's
structure and dynamics.
The instruments will also scrutinize the planet's surface for volcanic
activity. In addition, Akatsuki's Lightning and Airglow Camera will
hunt for lightning in order to settle a longstanding debate about how
is Venusian lightning generated in a dry atmosphere?
