The 12th international space station crew
turned its attention this week to experiment work aboard their microgravity
home and laboratory. They captured spectacular images of Hurricane Wilma
(available on the Web and NASA TV) and prepared for a spacewalk.
Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev
began reviewing procedures for the first station-based spacewalk using U.S.
suits since 2003.
During the November 7, five and one half hour spacewalk, they will install
a new video camera on the far end of the station's P1 (port) truss. They
also will remove a probe that measured the electrical potential around the
station from the top of the P6 truss
Yesterday, the station's atmosphere was repressurized with oxygen from storage
tanks on the docked Progress supply ship. Russian specialists are preparing
a troubleshooting plan for the Elektron, the primary oxygen generation system
on the station. It stopped working late last week.
Russian technical specialists are examining what caused the abort of a planned
altitude reboost Tuesday using Progress fuel and thrusters. Mission managers
believe Russian navigation computers properly shut down the thrusters when
they lost information about how they were performing. A planned test firing
of the thrusters Wednesday will gather more data for Russian engineers.
McArthur checked out a system to analyse exhaled gases inside the station.
The Pulmonary Function System took more than eight years of design, development
and testing on Earth by U.S. and European Space Agency scientists. It was
delivered to the station by the shuttle Discovery in July. McArthur and Tokarev
conducted the first of three sessions with the Renal Stone experiment. They
collected urine samples for return to Earth and logged all food and drink
consumed during a 24-hour period.
This ongoing experiment investigates whether potassium citrate can be used
to reduce the risk of kidney stone formation for space travelers. The citrate
minimizes kidney stone development on Earth.
Since urine calcium levels are typically much higher in space, astronauts
are susceptible to an increased risk of developing kidney stones. An understanding
of the crew's diet during the urine collection timeframes will help researchers.
They will determine if the excess calcium in the urine is due to diet or
a response to the microgravity environment. The payload operations team at
NASA's Marshall Space Flight Center, Huntsville, Ala., coordinates U.S. science
activities on the station.
During their six-month mission, McArthur and Tokarev will conduct at least
two spacewalks and oversee the arrival of the next Progress supply vehicle
in December. They also will relocate their Soyuz spacecraft to free the Russian
Pirs docking port for a later spacewalk. Pirs doubles as an airlock and docking
module.

Emily, W0EEC has created a website to allow the users of AO-7 to record
contacts, observations and use of the satellite more effectively at:
http://www.emilyshouse.com/experthams/ao7/main.php
This includes the ability to log contacts.
Mostly in mode B, ! with dx stations heard regularly,with some qrm on the 2m down link. But still plenty of traffic, showing that the old mode b transponder is much liked and rated. Tending to disappear or change modes part way through passes, perhaps due to poor solar lock?
ao7 seems to be changing its trend its spent a lot of time in mode A this month...why not try CW or phone ....100w eirp l/h circular uplink.......2/6db linear antenna on the down link are the requirements! Its poss to work mode A with less....stations worked this month inc:VA2JML UY5UZ K3SZH N8BBQ S57LM HB9DSU N1MIW.

There have been unconfirmed reports on the amsat-bb emailer that So-50 has shifted downlink frequency as much as 5khz up.
To switch the transmitter on, you need to send a CTCSS tone of 74.4 Hz. and then ctcss of 67hz to keep the bird open: its nice to see a bit more traffic on this bird this month.!INC: GU1OCN/P ON5NY
UO-11 OSCAR-11…semi operational
During the period 24 September to 25 October 2005 the VHF beacon on 145.826 MHz. resumed transmissions, as expected, on 30 September, sometime between 06:05 and 06:42 UTC passes. Reasonable signals were also captured on the 17:44 pass, later that day. However by the 16:49 UTC pass on 02 October, the beacon had switched OFF. Transmissions resumed on 21 October, and should continue until around 31 October. The on-board clock continues to show a very large error. Currently it is 19.2394 days slow, having lost six hours while the beacon was last OFF, ie. between 02 October and 21 October. When the beacon is ON, the clock is stable to within a few seconds. All the analogue telemetry channels, 0 to 59 are zero, ie they have failed. The status channels 60 to 67 are still working. The eclipses have now ended, and the satellite should be in continuous sunlight for the remainder of this year, and well into next year. This should help the satellite to continue transmitting, although continuous sunlight can cause problems due to excessive temperatures. The watchdog timer appears to be operating on the 20 day cycle, ie. approximately ten days ON followed by 10 days OFF. It appears to be unaffected by problems of the on-board clock. However, poor solar attitude, and battery problems, may be combining to produce a low line voltage. This causes the beacon to switch OFF prematurely, and resets the watchdog timer cycle. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Listeners to OSCAR-11 may be interested in visiting my website which contains an archive of news & telemetry data. It also contains details about using a soundcard or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry.

SSETI EXPRESS NEWS
The SSETI Express satellite launched at
06:52 UTC on Thursday, 27 October 2005 on board a Kosmos 3M launcher. One
hundred and three minutes later, exactly on schedule, the first signals
were heard form the groundstation in Aalborg, and two-way communication
was established. In addition to several successful communication sessions
with SSETI Express, two of the Cubesat passengers, UWE-1 and Xi-V, have
been heard by amateur radio operators around the world as well as by their
ground control stations.
The European Space Agency reported that on Thursday evening, 27 October SSETI
Express went into a safe mode due to an under voltage caused by battery charging
problems. The operations team is working actively to resume nominal operations
of the satellite and is receiving tremendous help in the process from the
amateur radio community. At the time of the anomaly many mission milestones
had already successfully been met."
For the past day no reliable reports of any signals from SSETI have been
received and the teams are reviewing all the telemetry already received to
fully understand what is happening on board. Initial review suggests that
there is a significant chance that the power supply problem may correct itself.
Graham Shirville, G3VZV, a member of the SSETI team, said, "If it does
not recover then it will be a sad end to a wonderful mission." Shirville
said ground controllers were going to attempt a blind command of the satellite
in an effort to revive the satellite, which carries an Amateur Radio package
and three CubeSat picosatellites. The spacecraft had been transmitting AX.25
telemetry at 9k6 bps on 437.250 MHz.
Amateur Radio operators are encouraged to continue monitoring for signals
from SSETI. ESA and the SSETI Association greatly value the input that we
are providing. Amateurs around the world are requested to continue to check
for signals on 437.250 MHz at the appropriate pass times. These signals may
be short bursts of 9k6 data every 18 secs or bursts of pulse telemetry every
30 secs. Signal reports that match the above should be e-mailed to missioncontrol@sseti.org
Ncube-2
The Norwegian student satellite, Ncube-2
is an experimental spacecraft that was developed and built by students
from four Norwegian universities. Data transmissions and digipeater use
1200 and 9600 bps.
Downlink 437.305 @ 1.5 watts. The first transmissions will be 20 minutes
after separation from SSETI Express. The message: "DE LA1CUB NCUBE2
FF LA1CUB" will be sent in morse at 26 words per minute using a 2400Hz
tone.
At the end of the message an unnumbered AX.25 packet is sent containing the
string: DE LA1CUB NCUBE2 NORWEGIAN CUBESAT - WWW.NCUBE.NO . The AX.25 header
will include Callsign: NCUBE, and Destination: EARTH.
UWE-1
The UWE-1 spacecraft is a registered Pico-satellite
of Julius Maximilians Universitaet Wuerzburg, Germany. Its research aim
is to test IP based telecommunications protocols in space.
Downlink 437.505 @ 1.0 watts. The communication protocol is AX25. The satellite
will transmit for about 1 sec every 1 minute.

P3E NEWS:
Peter Guelzow, DB2OS, President AMSAT-DL
and the P3-E Project leader wrote a report to update radio amateurs about
the progress of the satellite:
First of all I have to apologize for the little information about the P3-E
progress over the last few months. Updates were provided during presentations
at the recent AMSAT-UK Colloquium. We also publish news in the AMSAT-DL magazine
which is also then reprinted in the AMSAT-NA Journal. To accommodate the
delays inherent in these publishing media we will provide information via
the AMSAT-DL website and e-mail such as the AMSAT-BB.
To improve communications with our membership and worldwide audience, AMSAT-DL
decided to improve the information flow on our website using a new content
management system (CMS, Mambo). Unfortunately this took much longer than
anticipated, but the new portal should be available to the public by December.
The CMS itself is almost fully functional, but we have to transfer and re-edit
all the information from our old website. As you can probably imagine, this
is still a lot of work. However, once it is running, we hope to put more
information on-line and also have a news section with more regular updates.
Indeed, because of this, we almost stopped updating the old website.
So far, AMSAT P3-E is making good progress, but slowly. Some modules have
already arrived in Marburg for integration, but other module builders are
making use of the additional time due to the yet unknown launch date.
The wiring harness is defined and will be built and integrated into the spacecraft
soon. Thanks to the CAN-bus and our CAN-DO module controllers, it will be
not such a big beast as on previous P3 satellites.
Additional radiation testing has been performed on the CAN-DO. The CAN DO
module and other selected electronic components for P3-E and P5-A were exposed
to protons with an energy of 60 MeV. The CAN-DO module stopped operating
at 61 krad, which is good for a projected mission duration of more than 10
years. Since the CAN-DO module is one of the most critical parts on P3-E
and P5-A, this gives us a better feeling that it should not suffer from radiation
induced failure. A radiation test is also planned for the IHU-3 within the
next couple of weeks.
Very good progress was also reported from the development teams of the new
IHU-3, both in terms of hardware and software. While a big step forward was
made, the full integration and testing of the operational IPS software and
all it's functionality (including the turbo codes and software defined modems)
is the next step.
In addition to the analog transponders flying on P3-E, we will also look
into the possibility to have an SDT (software defined transponder) flying
on P3-E for the first time. The recent developments on Software Defined Radio
technologies and STELLA, may give us completely new ideas. While this is
quite late and various details must still be discussed, the necessary RF
interfaces are already available in the module space. Expect to hear more
about this in the future updates.
An extremely critical step was taken a few days ago when Ariane 5 scored
a double success for Arianespace with the successful launch of Syracuse 3A
and Galaxy 15 on-board flight V168.
While we do not yet have an official launch manifest, we are in full contact
with our partners at Arianespace. Everyone is working hard to find a suitable
slot for P3-E to the benefit of both sides. While the year 2005 is almost
over, our target to get P3-E into orbit is still 2006 and will remain so.
Clearly, the continuing success of the new Ariane 5 will help us too. Initial
arrangements for environmental testing, including vibration and thermal vacuum
testing are already made.
Indeed, we still need a lot of support for P3-E and donations. But with all
the contributions we are receiving, P3-E will be truly another international
satellite. I'm in particular delighted, that AMSAT-NA joined and supports
the P3-E project. We have excellent personal relationship between our organisations
and apart from the fun, things are developing really good to the benefit
of EAGLE, P3-E and all the projects on the horizon.
SuitSat Readies for Operation
on 145.990 MHz
Now is the time to begin preparing your
amateur radio station to receive signals from SuitSat, the most unusual
Amateur Radio satellite ever orbited. SuitSat amateur radio equipment will
be installed inside a surplus Russian Orlan spacesuit. It will become an
independently orbiting satellite once it is deployed by the crew of the
International Space Station during an extravehicular activity, tentatively
planned around December 8, 2005.
Running only on internal batteries within the spacesuit, SuitSat will have
a limited, but interesting lifetime beaming down special messages and an
SSTV image as it floats in space. Having no external thrust to adjust its
orbit after it is hand-deployed during the EVA, SuitSat will be in a free-floating,
but decaying orbit around Earth. It is expected to remain in orbit up to
6 weeks after being deploy
The image on the left shows SuitSat in it's
flight configuration. You can see the electronics control panel on the
top of the helmet along with the SuitSat antenna. A new handle has been
added around the midsection of the suit (black stripes). The handle is
an important addition that will allow the astro/cosmonaut launching the
suit to move it safely. [Photo credit to Steve Bible N7HPR - Thanks Steve!]
SuitSat's transmissions will include special international voice messages,
spacesuit telemetry, and a pre-programmed SSTV picture on its 145.990 MHz
FM downlink. If you have already received the packet station or heard the
ISS crew on 2-meter voice, then you already have most of what you need. Amateur
radio signals from the ISS can be received with a 2 meter vertical antenna
so an elaborate tracking system is not necessary. The SSTV signal can be
decoded with personal computer SSTV software after you connect your computer
to the speaker output of your radio.
